Dry dock wall construction process
The invention provides a dry dock wall construction process. The dry dock wall construction process comprises the following steps that 1, a foundation pit is excavated, and one surface of the finallyexcavated foundation pit is step-shaped; 2, a plurality of parallel cast-in-place piles are constructed at the bottommost end of the step-shaped face of the foundation pit; 3, buttress concrete is poured on the plurality of cast-in-place piles in two times; and 4, the foundation pit in the first step is backfilled in a layered mode, one face of a structure formed through backfilling is also in a step shape finally, and the number of the step-shaped steps in the fourth step is smaller than that of the step-shaped steps in the first step. According to the dry dock wall construction process, thefoundation pit is excavated in a step shape, the gradient of the slope of the foundation pit can be reduced, and construction is facilitated. Cast-in-place pile construction is conducted at the bottomend of the step-shaped foundation pit, the bearing capacity of the pit bottom of the foundation pit can be protected, and the step-shaped face of the foundation pit can be prevented from collapsing.
本发明提供了一种干船坞坞墙施工工艺，包括以下步骤：步骤一、开挖基坑，最终开挖的基坑一个面呈台阶状；步骤二、在基坑呈台阶状面的最底端施工多根平行的灌注桩；步骤三、在多根灌注桩的上方分两次浇筑扶壁混凝土；步骤四、分层回填步骤一的基坑，最终回填形成结构的一个面也呈台阶状，步骤四的台阶状台阶数少于步骤一台阶状的台阶数。本发明呈台阶状开挖基坑，既有利于降低基坑斜面的坡度还便于施工。本发明在台阶状基坑的底端进行灌注桩施工，既能保护基坑坑底的承载能力又能防止基坑呈台阶状的面坍塌。
