After the measured value and the measured coordinates are recorded, a series of operation swinging the hull by an approximate diameter of the tremide pipe 6 is repeated. After the completion of work within a required width, a series of operation moving the hull forward and backward by the diameter of the tremie pipe is repeated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a rubble stone that can be used to measure the level of rubble stone, earth and sand, etc. in real time when the gravel stone, earth and sand, etc. are thrown into the water bottom using a tremie pipe.
It relates to the method of inputting earth and sand.

[0002]

2. Description of the Related Art For the construction of breakwaters and seawalls, when a caisson is installed on the bottom of the water, rubble stones are thrown into the water bottom of the installation area, and the level of the rubble is leveled to form a rubble mound. In addition, sand is put in to lay a sand mat before placing sand piles for drains on the bottom of the water.

Therefore, in order to throw rubble stones, earth and sand, etc. to the bottom of the water by using a tremie pipe arranged on the bow of a work boat,
Conventionally, the level of the rubble and earth and sand input area is measured in advance with an acoustic sounder, and every time the gravel and earth and sand are put into the tremie pipe, the worker lowers the red, that is, the rope with a weight to adjust the water depth. It was measured to roughly confirm whether or not it was thrown into a predetermined level, and after the loading was finished, the level of the throwing area was measured with an acoustic sounder to check the height.

Therefore, when throwing in rubble stones, earth and sand, etc., it is not possible to accurately know the throwing height. Therefore, after finishing the throwing work, it is necessary to rework a portion higher or lower than a predetermined height, thus improving work efficiency. There was a problem that was bad.
In addition, there is a problem that the thickness of the thrown rubble, earth and sand, etc. is not known at the time of throwing.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems, and when gravel stones, earth and sand, etc. are thrown in using a tremie pipe, they are thrown in almost in real time. The problem to be solved is to provide a method for charging rubble stones, earth and sand, etc., which can measure the height and improve the efficiency of the charging operation.

[0006]

[Means for Solving the Problems] As means for solving the above problems, the method of throwing rubble stones, earth and sand, etc. of the present invention is as follows.
While checking the hull position with a positioning device, such as an automatic tracking type positioning device, put the rubble, earth and sand, etc. through the tremie pipe placed on the work boat moored so that it can swing at a predetermined position, Four sets of depth sounders arranged in front, back, left and right, for example, each depth in front, back, left and right are measured by Auto Red, and after recording each measured value and measured coordinates, the above series of swinging the hull by about the diameter of the tremie pipe After the work is repeated and the work within the swing of the required width is completed, the hull is moved in the width direction by about the diameter of the tremie pipe, and the series of work is repeated. .

By the above work, the depth of water before and after the throwing of rubble, earth and sand, etc. can be measured almost in real time by the sounding machines at the left, right, front and back of the tremie pipe, and the diameter of the tremie pipe in the swinging direction and the front-back direction of the hull is almost the same. The input thickness of rubble stones, earth and sand, etc. in the moving water area can be measured immediately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for throwing rubble stones, earth and sand, etc. according to the present invention will be described below with reference to the drawings. This embodiment is a case of throwing rubble stones, and FIG. 1 shows a rubble stone throwing system by the throwing method. 2 is a front view showing a CRT screen display example of the construction management and monitoring room of FIG. 1, and FIGS. 3 and 4 are FIG.
It is an explanatory plan view of a construction example of the tremie pipe.

First, as shown in FIG. 1, a positioning device, for example, an automatic tracking type positioning device 1 known as a trade name or a geodimer is installed at a known fixed point on land or on water, and is attached to this. A data wireless transmission device, for example, a telemetry transmitter 2, and a battery 3 and a solar cell 4 as power sources are arranged. Next, the work boat 7 having the telescope type tremie pipe 6 that can be raised and lowered by the winch 5 arranged on the bow or the like is moored at a predetermined position so as to be swingable by a Christmas tree anchor, a spud or the like (not shown).

Around the above-mentioned tremie pipe 6, a total of four sets of sounding machines, for example, an auto red 8 are arranged in the longitudinal direction and the lateral direction of the hull of the work boat 7. Further, a reflection prism 9 for reflecting the light L from the automatic tracking type positioning device 1 is arranged at a predetermined position of the work boat 7, and a gyro compass 10 for measuring the direction of the hull in the marine vessel and a data wireless transmission device, for example, telemetry. The receiver 11 and the construction management monitoring board 12 having the CRT screen 12A shown in FIG. 2 are arranged.

Therefore, while confirming the position of the hull of the work boat 7 by the automatic tracking type positioning device 1, the hull is confirmed at a predetermined position, and rubble stones are supplied from the upper part of the tremie pipe 6 via the inside thereof. After throwing the rubble stones G into the water bottom, the water depth is measured by four sets of auto reds 8 arranged in the front, rear, left and right around the tremie pipe 6, and the measured value and the measured coordinates are recorded.

The automatic tracking type positioning device 1 has a function of predicting the movement of the reflecting prism 9 and automatically tracking it. However, once the reflecting prism 9 is missed, the position of the reflecting prism 9 is searched for. There is a possibility that it may take time before the reflection prism 9 is caught again by rotating in the horizontal direction and the vertical direction. Therefore, a small video camera is attached to the collimation window of the automatic tracking positioning device 1, and a remote control knob is arranged on the automatic tracking positioning device 1 via the CPU, so that the work boat 7
A monitor TV that captures images from a small video camera and a remote control knob that controls the sighting direction of the automatic tracking positioning device 1 are provided in the ship's cabin to be connected to the CPU, and the video camera data is transmitted to the monitor TV. Then, a transmission device such as a parabolic antenna for transmitting the data of the remote control knob in the marine vessel to the CPU on the side of the automatic tracking positioning device 1 is installed on the work boat 7
And the automatic tracking positioning device 1 are arranged in the vicinity, respectively, so that the image of the collimation window of the automatic positioning device 1 displayed on the monitor TV when the automatic positioning device 1 misses the reflection prism 9 is viewed. While operating the remote control knob, the reflection prism 9 can be searched for.
The time to catch can be shortened.

Further, in FIG. 1, 8A is a weight of each auto red 8, 8B is an auto red control panel, and 6B is two sets of tremie tube payout meters. next,
When the above-described work is repeated and the swing of the hull with a predetermined width is completed, the hull is moved in the front-rear direction by about the diameter of the tremie pipe 6, and the above-described series of work is repeated.

After repeating the work of swinging by the diameter of the tremie pipe 6 and introducing the rubble G to measure the depth, the hull is moved forward and backward by the diameter of the tremie pipe 6 and the same operation is performed. The work will be repeated over the entire input water area. According to the charging method described above, the automatic tracking type positioning device 1 and the gyro compass 10 determine the position of the water depth measured by the auto red 8.

That is, the state in which the rubble is being thrown while swinging as shown by the initial arrow S of the work boat 7 in which the tremie pipe 6 is installed is illustrated in FIG. Move from the construction site X by about the diameter of the tremie pipe 6 and repeat the swing to rubble stones,
In the case of a right swing in Fig. 4 which explains the state where the earth and sand are being thrown in, in the case of a right swing, the water depth after throwing in the swing S direction is measured (post-measurement) with the auto red shown in A, and the auto shown in C is shown. Measure the water depth before throwing in the swing S direction with red (preliminary measurement), measure the water depth after advancing in direction F with B auto-red (post-measurement), and advance with arrow F with auto red shown D. The water depth will be measured (preliminary measurement) before the direction is input.

In FIG. 3, the above explanation is for the case where the swing of the arrow S is a right swing, and in the case of a left swing, the pre-measurement and the post-measurement of the auto red shown by C and A are interchanged, and in FIG. The value measured by the auto red shown in Fig. 3 can be used to judge the amount of forward movement of the hull whether or not the input position of the tremie pipe 6 is a predetermined distance away from the place where it was constructed last time. Table 1 summarizes the functions of Auto Red 8 indicated by C, D. Table 1
Is a table explaining the function of each auto red in FIGS. 3 and 4.

[0017] Further, in this embodiment, the pitching meter and the rolling meter are used as the work boat 7 although the influence of the motion of the hull is not taken into consideration.
If it is placed at, it will be possible to take into consideration the influence of the shaking of the hull. Although the present embodiment has been described for the case of rubble, it is also applicable to the case of earth and sand.
