Environmental protection construction method applied to underwater bored piles

Abstract

The invention discloses an environment-friendly construction method applied to an underwater borehole cast-in-place pile. The environment-friendly construction method comprises the following steps of (a) pollution source analysis; (b) retaining wall construction preparation; (c) retaining wall establishment; (d) waste slag site selection; (e) waste slag site protection and greening; (f) underwater borehole environmental protection measures; (g) borehole cleaning; (h) borehole sediment treatment. According to the environment-friendly construction method disclosed by the invention, vegetation on a retaining wall protection side slope can be established through analyzing pollution sources which are easily generated during a construction process of the underwater borehole cast-in-place pile; a waste slag site is designed for treating the sediment in a concentrated way, and the sediment is prevented from polluting water quality and soil; meanwhile, construction procedures which are easily cause environment pollution are optimized, and thus the underwater borehole cast-in-place pile can be constructed under a green and environment-friendly condition.

Description

technical field [0001] The invention relates to an environment-friendly construction method, in particular to an environment-friendly construction method applied to underwater bored piles. Background technique [0002] The cast-in-situ pile system refers to the pile holes formed in the foundation soil by means of mechanical drilling, steel pipe extrusion or manual excavation on the project site, and piles made by placing steel cages and pouring concrete in them, depending on the method of hole formation. , Cast-in-situ piles can be divided into several categories such as immersed tube piles, bored piles and hole-dug piles. Bored pile is a pile type defined according to the classification of pile forming methods. The underwater bored pile is a type of bored pile constructed underwater. [0003] The construction process of underwater bored piles cannot be directly observed, and the sediment produced during construction will have a negative impact on water quality, causing wa...

AI Technical Summary

Problems solved by technology

[0003] The construction process of underwater bored piles cannot be directly observed, and the sediment produced during construction will have a negative impact on water quality, causing water pollution and seriously affecting the farmland on both sides of the river.

At the same time, when the existing construction method of underwater bored piles reaches the slope, over-excavation, over-occupation, and soil erosion are prone to occur, which poses a huge threat to the vegetation on the bank

In severe cases, it will destroy the ecological environment on the shore and cause a large number of vegetation to die
