Problems solved by technology

The problem is that it will leave a permanent support structure in the foundation pit, and consume a lot of materials (reinforced concrete consumption), which is uneconomical and has a long construction period for underground foundation structures that do not require permanent support.
However, welding is required for connection, and it is difficult to disassemble and reuse

Embodiment 1

[0031] The steel sheet pile support construction under the deep soft foundation in this embodiment goes through the following steps (mainly refer to Figure 4 ):

[0032] The first step, construction preparation - build drainage ditches 1 around the foundation pit, and arrange drainage wells at the four corners of the pit to pump out the groundwater; evenly coat the locks of the steel sheet piles with mixed oil, and the volume ratio of the mixed oil is butter: dry bentonite: Dry saw foam = 5:4-6:2-4, this kind of mixed oil has low cost and good waterproof and sealing effect; if necessary, the surface of the steel sheet pile is painted with anti-corrosion paint, and the lock of the steel sheet pile is coated with a water-stop sealant to ensure anti-corrosion , Sealing effect.

[0033] The second step is to build the guide purlin——weld the rectangular guide purlin 3 of the frame structure according to the inner profile of the foundation pit, and after forming a circle, fix the ...

Abstract

The invention relates to supporting and construction method of a steel sheet pile under soft foundation of a high flow plastic deep layer, and belongs to the technical field of building construction.The supporting and construction method of the steel sheet pile under the soft foundation of the high flow plastic deep layer comprises the steps of construction preparation, construction of guiding purlins, injection of a steel sheet pile, excavation and water drainage, foundation trench interior construction and removing of the steel sheet pile. The supporting and construction method of the steelsheet pile under the soft foundation of the high flow plastic deep layer is simple and easy to implement during the construction process, is easy to popularize, and can effectively stop water and prevent piping, and almost all supporting and protecting facilities can be reused after being disassembled.

Description

technical field [0001] The invention relates to a foundation pit support construction method, in particular to a steel sheet pile support construction method under a high-flow plastic deep soft foundation, and belongs to the technical field of building construction. Background technique [0002] With the increasingly complex built environment, it is often encountered that infrastructure construction is carried out in unfavorable areas such as seashores. In these "bad" areas, the amount of silty land is huge and the silt is deep, which brings challenges to engineering construction - the construction of docks, road network engineering, bridge and tunnel engineering foundations, and high-rise building foundations in soft base areas all have to wear For the deep soft foundation, what kind of excavation method should be adopted and how to make the safety guarantee measures of the excavation process both economical and fast have become major issues in the construction industry. ...
