Foundation pit enclosing structure adopting fill reinforced concrete steel pipes
The invention provides a foundation pit enclosing structure adopting fill reinforced concrete steel pipes, and belongs to the field of building foundation pit enclosing. According to the technical scheme, the multiple fill reinforced concrete steel pipes are connected into a row through lock catches, in the fill reinforced concrete steel pipes, reinforcement cages are inserted into the steel pipes, and the spaces between the reinforcement cages and the inner walls of the steel pipes are filled with non-contract concrete. The reinforcement cages and the steel pipes have the same circle centers.The heights of the lock catches are equal to the pipe lengths of the fill reinforced concrete steel pipes, each lock catch is composed of two portions with the cross section shapes mutually lapped and buckled left and right and front and back, and the two portions are welded to the outer walls of the adjacent fill reinforced concrete steel pipes correspondingly. By means of the foundation pit enclosing structure, the problem that the steel strength of open steel pipe piles is hardly exerted fully is solved, and the problem that the construction quality of conventional bored row piles is hardly controlled can be avoided.
本发明属于建筑基坑支护领域的一种采用内填钢筋混凝土钢管的基坑围护结构，技术方案为：数个内填钢筋混凝土钢管之间通过锁扣连接成排，内填钢筋混凝土钢管为钢管中插入钢筋笼，无收缩混凝土填充钢筋笼和钢管内壁之间的空间；钢筋笼与钢管同圆心；锁扣的高度与内填钢筋混凝土钢管的管长相同，锁扣为横截面形状为左右和前后互相搭接相扣的两部分组成，两部分分别焊接在相邻内填钢筋混凝土钢管的外壁上。其解决了开口钢管桩的钢材强度难以得到充分发挥的问题并可避免常规钻孔灌注排桩施工质量难以控制的问题。
