specific Embodiment

[0029] see figure 1 and figure 2 , the application provides a specific embodiment of a quicksand soil foundation pit excavation and support technology, which includes the following steps:

[0030] Carry out excavation in a preset area until the excavation reaches the groundwater level; in this embodiment, the steel bars required for preparing the foundation beam 1 and the wall bricks or concrete for building the wall body 2 need to be prepared before construction. The materials used in this example are all commonly used materials on the existing construction site, which are very convenient to obtain, and do not need to be purchased or transported separately.

[0031] The preset area is the area that needs to be excavated for the foundation pit 6 pre-selected during construction. This embodiment is suitable for quicksand geology close to rivers and coasts, because the groundwater level is high and is quicksand geology. The outflow will cause scouring, causing quicksand to fl...

Abstract

The invention is suitable for the technical field of foundation construction, and particularly provides a quicksand soil foundation pit excavation supporting technology and a supporting structure, and the technology comprises the following steps: carrying out excavation in a preset area until the excavation reaches an underground water level; excavation is paused, a circle of foundation beam is poured around the periphery of the excavated foundation pit, and a wall body is arranged on the upper portion of the foundation beam; the excavation is continued, the foundation beam uniformly sinks along with the increase of the excavation depth, and the foundation beam is used for supporting and water stopping and preventing the side wall from collapsing; the foundation pit is excavated to the target depth, a concrete cushion layer is poured in the foundation pit, a drainage ditch and a water collecting well are reserved and used for draining and collecting accumulated water in the foundation pit, and the supporting structure comprises a foundation beam and a wall in the technology. The invention discloses a quicksand soil foundation pit excavation supporting process, and aims to solve the technical problems of long construction period and high cost of an existing excavation measure when the size and depth of a foundation pit are not large in the prior art.

Description

technical field [0001] The present application relates to the technical field of foundation construction, and more particularly, to a support technology and a support structure for excavation and support of quicksand soil foundation pits. Background technique [0002] The excavation of quicksand geology has always been a complex problem in engineering construction. In many cases, quicksand will cause the collapse of the foundation pit excavation, and even sometimes cause casualties and mechanical damage. In order to avoid the quicksand phenomenon during the excavation process, it is often necessary to It costs a lot of money, and the current measures are as follows: 1. The method of digging and throwing large stones is to dig the earth in sections, so that the speed of digging soil exceeds the speed of sand production. After digging to the elevation, immediately spread bamboo and reed mats, and throw large stones. , to balance the dynamic water pressure and suppress the quic...
