Sand layer foundation pit dewatering and water guiding structure
The invention relates to a sand layer foundation pit dewatering and water guiding structure. The dewatering and water guiding structure comprises a plurality of main pipelines, a plurality of transverse branch pipes, a plurality of longitudinal branch pipes and gauze elements wrapping the branch pipes. Through holes are distributed on the pipe wall of each branch pipe. A part of the main pipeline surrounds the inner side of the foundation pit sideline by a circle to form an outer frame, and at least one main pipeline extending in the longitudinal direction is arranged in the outer frame. Transverse branch pipes and longitudinal branch pipes are distributed in a unit frame defined by the main pipeline in a crossed mode. The cross nodes between the main pipelines and the cross nodes between the main pipelines and the branch pipes are communicated. Cross nodes between the transverse branch pipes and the longitudinal branch pipes are of non-communicated matching structures. One main pipeline in the outer frame is connected to the water collecting tank through a pipeline. On the premise that the foundation is not disturbed basically and the stability and the safety of the foundation pit are ensured, the foundation pit and the foundation are subjected to dewatering in cooperation with the stable depth of the tube well, the problem that the foundation pit and the foundation are prone to instability and damage in geological environment construction which is unfavorable for dewatering is solved, and foundation construction conditions are established.
本发明涉及一种砂层地基基坑降水导水结构，包括多条主管道、多条横向支管、多条纵向支管及包裹在各支管外的纱网。各支管的管壁上分布设有通孔。部分主管道相距基坑边线内侧环绕一圈形成外框且在外框内至少设有一条沿纵向延伸的主管道。在由主管道围成的单元框内交叉地分布设有横向支管和纵向支管。主管道之间的交叉节点以及主管道与支管之间的交叉节点均相连通。横向支管与纵向支管之间的交叉节点为非连通的匹配结构。外框中的一条主管道通过管路连接至集水池。本专利能在地基基本不被扰动、确保基坑稳固安全的前提下，配合管井稳降深来进行降水，克服了不利降水的地质环境施工中，容易对基坑及地基造成失稳破坏的问题，建立了基础施工条件。
