A diaphragm wall pit structure beneficial to soil body dewatering

Abstract

The present application relates to a kind of earth wall slag soil pit structures facilitating soil body dewatering, using pit top beam, pit bottom beam and retaining plate instead of traditional reinforced concrete bottom plate, pit bottom beam is filled with broken stone.This application optimizes and discards the traditional reinforced concrete bottom plate, and sets beam instead of bottom plate, and the broken stone between the beams can be filled with broken stone.There is a gap between the broken stones, so the hollow design is used instead of the closed reinforced concrete bottom plate, and the slag soil flows to the bottom under the action of its own gravity, and is reinforced and supported by the beam set at the bottom, which not only improves the strength and stability of the earth wall, but also effectively avoids the problem of material waste caused by the lack of workers' saving consciousness during the construction of the traditional reinforced concrete bottom plate.

Description

TECHNICAL FIELD

[0001] The present application relates to a slag pit pouring, in particular to a wall slag pit structure beneficial to soil drying. BACKGROUND

[0002] At present, when the slag pit is poured, the amount of concrete and steel bars used is large. Therefore, the traditional reinforced concrete bottom plate is abandoned, and the pit top beam, pit bottom beam and retaining plate are arranged to replace the reinforced concrete bottom plate, and the pit bottom beam is filled with gravel. There are gaps between the gravels, so the hollow design is used to replace the traditional reinforced concrete bottom plate with poor water permeability, and the slag soil flows to the bottom of the pit under the action of its own gravity, and the water is dried through the gravel filling at the bottom of the slag pit. SUMMARY

[0003] The present application is to propose a wall slag pit structure beneficial to soil drying, which is simple and effective, low in cost, and can improve the construction efficiency.

[0004] In order to achieve the purpose of the present application, the technical scheme adopted by the present application is as follows:

[0005] A wall slag pit structure beneficial to soil drying, which uses pit top beam, pit bottom beam and retaining plate to replace the traditional reinforced concrete bottom plate, and the pit bottom beam is filled with gravel.

[0006] Further, the retaining plate is made of 300mm × 2500mm reinforced concrete plate and A12@200mm steel bar, the retaining plate is buried 2m deep and 0.5m higher than the outdoor ground level, and the pit top beam and the pit bottom beam support the balance of earth pressure.

[0007] Further, the pit top beam and the pit bottom beam are made of 700mm × 800mm reinforced concrete beam, and the steel bars are made of 14A16 longitudinal reinforcement and 2 limbs A12@200mm stirrup connected with the retaining plate.

[0008] Further, the gravel is made of 24 particle size gravel, and the filling height is 1 / 2 of the pit bottom beam.

[0009] The beneficial effects of the present application are:

[0010] The present application balances the earth pressure by arranging the pit bottom beam to reinforce and support the slag pit, which not only saves the amount of concrete and steel bars used when the slag pit is poured, saves the construction cost, but also can use the pit bottom gravel layer to dry the slag soil. The method is simple and effective, low in cost, and can improve the construction efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0013] The application will be further described below in connection with specific embodiments. It should be understood that these embodiments are only used to illustrate the application and not used to limit the scope of the application. Furthermore, it should be understood that those skilled in the art can make various modifications or changes to the application after reading the content taught by the application, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0014] As Figure 1 shown in Figure 2, a soil drying-friendly diaphragm slag pit structure of the application discards the traditional reinforced concrete bottom plate and sets a pit top beam, a pit bottom beam and a retaining plate instead, and the pit bottom beams are filled with gravel.

[0015] There are gaps between the gravels, so the hollow design is used to replace the traditional reinforced concrete bottom plate with poor water permeability. The slag flows to the bottom of the pit under the action of its own gravity, and the water is drained through the gravel filling at the bottom of the slag pit. By setting the pit bottom beam to balance the earth pressure, the slag pit is reinforced and supported, which not only saves the amount of concrete and steel during the pouring of the slag pit, saves construction cost, but also can use the gravel layer at the bottom of the pit to drain the slag. This method is simple and effective, low in cost, and can improve construction efficiency.
