The invention provides a construction method for supporting structure of deep foundation pit, which includes adding temporary steel support near the upper part of the reinforced concrete support before the construction of the reinforced concrete support. The construction steps of the reinforced concrete support include steel bar binding, formwork erection, concrete pouring, maintenance and demolition of formwork. The steel support is composed of steel pipe joint, movable end and fixed end. The steel support is connected by embedded steel plate or steel bar in the enclosure structure; the construction of concrete support is carried out in corresponding places; and the steel support is dismantled after the strength of concrete support reaches the design requirements. The method of the invention can make up for the condition that the enclosure structure has no effective support during the construction of reinforced concrete support, and reduce the deformation of the enclosure structure during the construction of reinforced concrete support. When the reinforced concrete support reaches the design requirements, the temporary steel support should be removed. So as to ensure the stability and effectiveness of the deep foundation pit retaining system, and provide a strong guarantee for the construction of deep foundation pit.
【技术实现步骤摘要】
深基坑的支撑结构的施工方法
本专利技术涉及一种深基坑的施工方法,特别涉及一种深基坑的支撑结构的施工方法。
技术介绍
众所周知,在现有技术中,钢支撑是深基坑最常用的支撑形式。钢支撑的自重小,可以随挖随撑,施工方便,可回收再利用,具有经济性、环保性等特征,但钢支撑的刚度小、整体变形大,在基坑深度越深、周边建构筑物越复杂的情况下,仅采用钢支撑体系将不能满足深基坑开挖对支撑体系的要求。因此,需要一种能够满足深基坑开挖对支撑体系要求高的深基坑的支撑结构的施工方法。
技术实现思路
有鉴于此,本专利技术提供一种深基坑的支撑结构的施工方法,以解决现有技术中深基坑施工过程中围护结构无支撑或支撑不足导致围护结构变形的问题。为了实现上述目的,本专利技术提供一种深基坑的支撑结构的施工方法,所述方法包括:S1:架设钢支撑,用以对深基坑的围护结构进行临时支撑;S2:在所述钢支撑附近设置钢筋混凝土支撑,对所述深基坑的围护结构进行支撑。可选的,所述S1具体包括:S11:在所述围护结构上设置围檩;S12:将所述钢支撑架设在所述围檩上。可选的,所述设置围檩具体包括:S111:在所述围护结构上测量放线定位 ...
