Background

At present, a supporting structure form of a soft soil foundation pit generally adopts a cement soil gravity type enclosure wall, a cast-in-situ bored pile and an in-pit inner support or a vertical steel pipe front support supporting structure, but the three have respective advantages and disadvantages, but the stability of the supporting structure is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the stability of the current supporting structure is relatively poor and providing a higher hydraulic structure excavation supporting precipitation device of stability.

In order to achieve the above purpose, the utility model adopts the following technical scheme: this hydraulic structure excavation supporting dewatering device, prop up the backplate including the foundation ditch, backplate and bottom plate fixed connection are propped up to the foundation ditch, prop up on the backplate with first fixed plate fixed connection, be equipped with the screw rod between two first fixed plates, first fixed plate is articulated with screw rod one end, the cover has adjusting nut on the screw rod, adjusting nut installs on the sleeve and can be on the sleeve free rotation, the sleeve other end is articulated with the second fixed plate, second fixed plate and slider fixed connection, slider and spout sliding connection, the spout is located the bottom plate, the spout both ends are equipped with the fixed slot, can insert the dog in the fixed slot and fix the slider, dog and handle fixed connection.

Furthermore, two water collecting tanks are arranged on the bottom plate, the water collecting tanks are fixedly connected with one end of the downcomer, and the other end of the downcomer extends through the foundation pit supporting and protecting plate.

Furthermore, a plurality of anchor rods are arranged on the back surface of the foundation pit supporting plate.

Furthermore, the foundation pit supporting and protecting plate and the bottom plate form an angle of 90 degrees.

The technical effects are as follows: the utility model discloses an adjusting nut comes accommodate the lead screw and telescopic total length, and remove the distance that comes the regulating block to a foundation ditch backplate through the slider in the spout, make the device support the triangle when supporting a foundation ditch backplate be one-class waist straight angle triangle-shaped, the support intensity of device has been improved greatly, this excavation supporting simultaneously, design through the downcomer, domatic infiltration can directly be derived with the downcomer, domatic downcomer adopts ordinary plastic tubing, generally set up in seepage layer bottom, the angle is upwards slightly, and downcomer front end parcel has the nylon wire, can carry out simple filtration, prevent a large amount of silt from flowing out, and the cost is lower.

Detailed Description

Referring to fig. 1-3, a hydraulic structure foundation pit supporting and dewatering device comprises a foundation pit supporting and protecting plate 1, the foundation pit supporting and protecting plate 1 is fixedly connected with a bottom plate 3, the foundation pit supporting and protecting plate 1 is fixedly connected with a first fixing plate 6, a screw rod 7 is arranged between the two first fixing plates 6, the first fixing plate 6 is hinged to one end of the screw rod 7, an adjusting nut 9 is sleeved on the screw rod 7, the adjusting nut 9 is installed on a sleeve 8 and can freely rotate on the sleeve 8, the other end of the sleeve 8 is hinged to a second fixing plate 10, the second fixing plate 10 is fixedly connected with a sliding block 11, the sliding block 11 is in sliding connection with a sliding groove 12, the sliding groove 12 is located on the bottom plate 3, fixing grooves 13 are formed in two ends of the sliding groove 12, a stop block 14 can be inserted into the fixing.

The base plate 3 is provided with two water collecting tanks 5, the water collecting tanks 5 are fixedly connected with one ends of the downcomer pipes 4, and the other ends of the downcomer pipes 4 extend through the foundation pit supporting and protecting plate 1.

And a plurality of anchor rods 2 are arranged on the back surface of the foundation pit supporting and protecting plate 1.

The foundation pit supporting and protecting plate 1 and the bottom plate 3 form an angle of 90 degrees.

The working principle is as follows: when in use, the foundation pit supporting and protecting plate 1 is tightly attached to the slope wall of the foundation pit and fixed through the anchor rod 2, one end of the screw rod 7 is installed on the first fixing plate 6 on the foundation pit supporting and protecting plate 1, the total length of the screw rod and the sleeve 8 is adjusted through the screw rod 7 through the adjusting nut 9, the loop bar can be installed on the second fixing plate 10, the sliding block 11 moves in the sliding groove 12, the bottom plate 3, the foundation pit supporting and protecting plate 1, the screw rod 7 and the sleeve 8 form an isosceles right triangle to stop adjustment, the stop block 14 is inserted into the fixing grooves 13 at the two ends of the sliding block 11, the stop block 14 fixes the sliding block 11 and cannot slide in the sliding groove 12, thus the foundation pit supporting and protecting plate 1 is supported through the isosceles right triangle, the downcomer 4 is inserted into the foundation pit supporting and protecting plate 1, the front end of the downcomer 4 is provided with a nylon net, the slope wall forms suspension water flowing into the outer side, after being filtered by the nylon net, water flows into the water collecting tank 5 from the downcomer 4, and the normal operation of construction is not influenced.
