Embodiment 1

[0040] see Figure 1-6 , the present invention provides a technical solution: a foundation pit support system, including a support frame 1, a support frame 2 is fixedly connected to the bottom of the outer walls of both sides of the support frame 1, and the support frame 2 is away from the side of the support frame 1 The tapered part 3 is fixedly connected, and the support frame 2 is provided with an extension frame 4 on the top of the side close to the support frame 1, and the bottom of the inner wall on both sides of the extension frame 4 is fixedly connected with a cover plate 5, and the middle position of the bottom of the support frame 1 is A reinforcement device 6 is provided, and the middle position of the top of the reinforcement device 6 penetrates the support frame 1 and extends to the inside of the support frame 1 .

[0041] Wherein, the reinforcement device 6 includes a stable base 61, a mounting mechanism 64 is provided at the middle of the inner cavity bottom of ...

Embodiment 2

[0047] see Figure 1-6 , on the basis of Embodiment 1, the present invention provides a technical solution: a method for using the foundation pit support system, step 1: install the device on the bottom of the foundation pit, and insert the cone 3 into the inner wall of the foundation pit, The reinforcing device 6 is connected with the support frame 1, so that the bottom of the support frame 1 and the bottom of the foundation pit have a small amount of space;

[0048] Step 2: Insert the positioning frame 62 into the inside of the stable base 61, so that the grooves of the stable base 61 can fit the bottom of the foundation pit more closely, and use the installation mechanism 64 and the protection mechanism 65 for fixed connection to facilitate mutual cooperation;

[0049] Step 3: insert the reinforcing pile 641 into the foundation pit by using the driving part, and connect the adjusting housing 644 with the locking member 645, so that the device is fixed inside the adjusting h...

Abstract

The invention discloses a foundation pit supporting system which comprises a supporting frame, wherein supporting racks are fixedly connected to the bottoms of the outer walls of two sides of the supporting frame; conical parts are fixedly connected to the sides, far away from the supporting frame, of the supporting racks, and extension racks are arranged at the tops of the sides, close to the supporting frame, of the supporting racks; and covering plates are fixedly connected to the bottoms of the inner walls of the two sides of the extension racks, and a reinforcing device is arranged in the middle of the bottom of the supporting frame. The foundation pit supporting system provided by the invention belongs to the technical field of building engineering. The bottom of a foundation pit is fixed through a stable base, meanwhile, soil at the bottom can be extruded through formed grooves, so that the inner walls of the two sides of the foundation pit can make full contact, the inner supporting space can be increased through the positioning frame, convenient blocking and limiting at the inside are effectively guaranteed, the supporting area of the device is increased while the dismounting speed of the foundation pit support is accelerated, the stability of the internal support is further improved, and collapse of the foundation pit caused by water flow is prevented.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a foundation pit support system. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the method of setting the side slope can be used to stabilize the soil slope. The construction regulations are determined. If the excavation is deep and there are buildings nearby, the method of foundation pit wall support, shotcrete retaining method, etc. can be used. [0003] According to a foundation pit support system disclosed in Chinese Patent No. CN109914447B, through the connected support piles and reinforcement...
