Detailed Description
The present invention will be described in detail with reference to the drawings and specific embodiments, which are illustrative of the present invention and are not to be construed as limiting the present invention.
As shown in fig. 1 to 4, a foundation pit support system comprises an adjustable baffle 1, a sleeve 2 connected with the adjustable baffle 1, a pile 3 for fixing the sleeve 2, and a fixing member 4 fixed on the adjustable baffle 1, wherein the sleeve 2 is sleeved on the pile 3 to enable the adjustable baffle 1 connected with the sleeve to move up and down in the height range of the pile 3; the fixing part 4 is provided with a fixing part 41 and a detachable staple 42, the detachable staple 42 penetrates through the adjustable baffle plate 1 to be connected with the fixing part 41, a grouting channel 411 is arranged on the fixing part 41, and the grouting channel 411 hardens the space around the fixing part 41 through concrete.
In use the adjustable baffle 1 is integrally formed with the sleeve 2 and the adjustable baffle 1 is divided into 5 gauges of 500 x 800mm, 800 x 800mm, 1000 x 800mm, 1200 x 800mm and 1500 x 800mm (where 800 is the height in each gauge).
In use the half diameter of the sleeve 2 is much larger than the half diameter of the pile 3 or there must be clearance between the sleeve 2 and the pile 3.
In use the adjustable blind 1 is a precast concrete slab.
The construction steps and the working principle are described in detail: during construction, firstly, the pile 3 is vertically dug according to the specification distance of the adjustable baffle 1, a foundation pit is dug downwards, and when the height reaches the specification height of the adjustable baffle 1, the crane sleeves the adjustable baffle 1 on the pile 3. After the adjustable baffle plate 1 is fixed, the fixing part 41 is inserted into the position of the adjustable baffle plate 1, then high-pressure pouring (a pouring head is different from the detachable clamping nail 42, as shown in fig. 4) concrete is poured for hardening, finally, the detachable clamping nail 42 is used for locking the adjustable baffle plate 1, and the adjustable baffle plate 1 is mutually locked and fixed. When the foundation pit is dug continuously, the detachable clamping nails 42 are loosened to lower the adjustable baffle 1, and then the adjustable baffle 1 is added; the steps of constructing the fixing portion 41 and detaching the staples 42 are repeated.
When the adjustable baffle plate is reused, the adjustable baffle plate 1 can be detached for secondary use only by loosening the detachable clamping nails 42 (the fixing parts 41 can not be detached) and hoisting the adjustable baffle plate 1.
Furthermore, the fixing portion 41 is further provided with a fastening position 412, the fastening position 412 is located inside the fixing portion 41 and is communicated with the grouting channel 411, and the detachable staple 42 is fastened with the fastening position 412. During grouting, the detachable staple 42 is replaced with a grouting head, the grouting head is locked at the locking position 412, and high-pressure concrete enters the grouting channel 411 from the grouting head and is sprayed to the periphery of the fixing portion 41 from the grouting channel 411 to be hardened.
Specifically, sleeve 2 is equipped with the fixed ear 21 of symmetry, and a fixed ear 21 is as an organic whole with 1 steel bar connection of adjustable fender, is equipped with the connecting hole on another fixed ear 21, and the connecting hole is connected fixedly with the connecting block 11 of 1 opposite side of adjustable fender. The fixing lug 21 increases the contact area for convenient installation.
The foundation pit support system is characterized in that a plurality of adjustable baffles 1 are sleeved on a pile 3 through sleeves 2, and then the adjustable baffles 1 are reinforced and locked by fixing pieces 4.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
