Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the accumulated water in the outlet tank is pumped out through the drainage pump to complete the drainage of the foundation pit. Generally, this method can only drain the bottom of the foundation pit, and there is also a certain accumulation on the side wall of the foundation pit. However, the accumulated water on the side wall of the foundation pit cannot be discharged. When the groundwater level is higher than the bottom of the foundation pit, the side wall of the foundation pit also bears a large lateral pressure, which may easily lead to the collapse of the side wall of the foundation pit.

Embodiment Construction

[0043] The following is attached Figure 1-8 The application is described in further detail.

[0044] The embodiment of the application discloses a foundation pit supporting structure and a construction method thereof. refer to figure 1 , a support structure for a foundation pit 1, including a foundation pit 1 and a plurality of protective plates 2 spliced ​​with each other. A first splicing block 3 and a second splicing block 4 are respectively integrally formed at opposite ends of two adjacent protective plates 2 , and both the first splicing block 3 and the second splicing block 4 are arranged along the length direction of the protective plate 2 . The first splicing block 3 is spliced ​​and matched with the second splicing block 4, so as to facilitate the positioning and installation of the protective plate 2.

[0045] refer to figure 2 The side surface of the protective plate 2 attached to the side wall of the foundation pit 1 is provided with a through-groove 6 arran...

Abstract

This application relates to the field of foundation pit support, in particular to a foundation pit support structure and its construction method. The side wall of the protective plate is provided with a channel for the support tube to be accommodated. The support tube is detachably connected in the channel, and the end of the support tube protruding to the channel is provided with a plurality of seepage holes. There is an adjustment component for adjusting the water seepage of the seepage hole inside the pipe. Both ends of the support pipe are closed ends. There is a drainage cavity inside the protective plate, and the drainage cavity is located under the channel. The channel is connected to the drainage cavity. One side of the support pipe is provided with a drainage hole, and the drainage hole is connected with the communication hole. A drainage pipe is communicated, and a suction pipe is communicated between the water pump and the drainage chamber.

Description

technical field [0001] The present application relates to the field of foundation pit support, in particular to a foundation pit support structure and a construction method thereof. Background technique [0002] With the rapid development of the modern construction industry, there are more and more high-rise and super high-rise buildings. Due to the load on the upper part of high-rise and super high-rise buildings, most of them adopt compensatory foundations. The buried depth is large, and the excavation of the foundation pit is deep, especially when the deep foundation pit is excavated in the area with a high groundwater level, the soil aquifer will be cut off, and the groundwater will continue to seep into the foundation pit, causing quicksand, slope instability or foundation bearing power drop. [0003] An existing deep foundation pit drainage structure includes the outer wall of the deep foundation pit, the inner wall of the deep foundation pit outer wall is provided wi...
