Construction method for underground deep foundation pit of circulating water pump house and pit wall formwork supporting structure
The invention provides a construction method for an underground deep foundation pit of a circulating water pump house and a pit wall formwork supporting structure. The construction method comprises the following steps of a, digging a guide wall groove; b, binding a guide wall reinforcing mesh; c, erecting a guide wall formwork; d, pouring guide wall concrete; e, dismantling the formwork; f, slurry backfilling; g, digging underground diaphragm walls grooves; h, hoisting reinforcement cages into the underground diaphragm wall grooves; i, placing a concrete guide pipe; j, pouring the concrete into the underground diaphragm wall grooves; k, completing pouring of all the underground diaphragm walls; l, excavating a foundation pit slot; m, arranging horizontal H-shaped steel on the wall faces of the underground diaphragm walls in the pit slot, and a transverse supporting beam is arranged between vertical plates on the outer sides of the two pieces of H-shaped steel in a supporting mode; n, pouring the groove bottom face of the foundation pit; o, installing a foundation pit reinforcement cage; p, erecting an inner side formwork; q, pouring the wall of the foundation pit; and r, installing a reinforcement cage located on the foundation pit wall of the adjacent section above the poured section, and pouring the concrete. The construction method for the underground deep foundation pit of the circulating water pump house and the pit wall formwork supporting structure are simple in process and high in efficiency.
本发明提供了一种循环水泵房地下深基坑施工方法以及坑壁模板支护结构。施工方法包括：a、挖设导墙沟槽；b、绑扎导墙钢筋网片；c、支设导墙模板；d、浇筑导墙混凝土；e、拆除模板；f、回填泥浆；g、挖设地连墙沟槽；h、将钢筋笼吊入地连墙沟槽内；i、置入混凝土导管；j、向地连墙沟槽内浇筑混凝土；k、将地连墙全部浇筑完成；l、开挖基坑坑槽；m、在坑槽内地连墙的墙面上设置水平的H型钢，在两个H型钢的外侧的立板之间撑设横撑梁；n、浇筑基坑的槽底面；o、安装基坑钢筋笼；p、支设内侧模板；q、浇筑基坑坑壁；r、安装位于浇筑完成段的上方相邻一段的基坑坑壁的钢筋笼，浇筑混凝土。本发明工序简单，效率高。
