Working well with supporting system and construction method thereof
The invention relates to a working well with a supporting system. The working well comprises cast-in-place piles arranged in an annular mode and a well body, wherein the well body comprises a plurality of enclosing purlins and well walls, and the enclosing purlins and the well walls are sequentially and alternately connected in an overlapped mode; a lower waterproof structure is arranged between the lower end of each enclosing purlin and the corresponding well wall below the enclosing purlin, and an upper waterproof structure is arranged between the upper end of each enclosing purlin and the corresponding well wall above the enclosing purlin; first diagonal tension steel bars are arranged between the enclosing purlins and the cast-in-place piles on the outer side; second diagonal tension steel bars are arranged between the well walls and the cast-in-place piles on the outer side; and a plurality of longitudinal steel bars are arranged between the enclosing purlins and the well walls, and the two ends of each longitudinal steel bar are connected with the corresponding enclosing purlin and the corresponding well wall which are vertically adjacent. A construction method of the working well with the supporting system comprises the following steps that supporting piles and the cast-in-place piles are driven on the ground, and then a foundation pit is excavated; and the well pit is excavated in a segmented mode, the enclosing purlins are poured segment by segment, the well walls are poured, and a top plate is poured. The enclosing purlins do not need to be dismounted, the construction period is shortened, the manufacturing cost is reduced, and construction waste is also reduced.
本发明涉及一种带支撑系统工作井，包括环形布置的灌注桩；以及井体，所述井体包括多个围檩和井壁，各个围檩和井壁依次交替叠加连接；所述围檩下端与下方的井壁之间设置有下防水结构，所述围檩上端与上方的井壁之间设置上防水结构；所述围檩与外侧灌注桩之间设置第一斜拉钢筋；所述井壁与外侧灌注桩之间设置第二斜拉钢筋；各个围檩与井壁之间设置多根纵向钢筋，每根纵向钢筋两端均连接上下相邻的围檩和井壁。带支撑系统工作井的施工方法，包括以下步骤：在地面打支护桩、灌注桩，然后开挖基坑；分段下挖井坑、并逐段浇筑围檩、井壁浇筑、顶板浇筑。不用拆除围檩，节约了工期和造价，也减少了建造垃圾。
