Construction method of permanent and temporary combined integral basement ramp
The invention relates to a construction method of a permanent and temporary combined integral basement ramp. The construction method comprises the following steps: measuring on the ground and drawing a positioning line according to the positioning of a permanent ramp of a negative first layer in engineering design before excavation of a foundation pit; driving cast-in-place piles, tubular piles and row piles on the outer side of the permanent ramp along the positioning line every 2 meters to complete positioning and supporting structures of the permanent ramp; in the foundation pit excavation period, earthwork reservation is conducted according to the permanent ramp gradient; paving and pouring concrete on the slope surface of the permanent ramp, pulling anchor cables on the side surface, arranging a reinforcing mesh and spraying fine aggregate concrete; the lower temporary ramp is connected with the permanent ramp; earthwork is reserved in the process of excavating the negative second layer, reinforcing meshes are laid on the side face of the reserved temporary ramp earthwork, fine aggregate concrete is sprayed, graded broken stones are laid on the slope face, and steel plates are fully laid on the slope face; and after the whole foundation pit is excavated, the temporary ramp is dismantled, and permanent ramp formal pouring construction is conducted through the permanent ramp supporting structure constructed in the first step.
本发明涉及一种永临结合的整体地下室坡道的施工方法，在基坑开挖前根据工程设计中负一层永久坡道的定位在地面进行测量并画出定位线；沿定位线在永久坡道外侧每隔2米打灌注桩、管桩以及排桩，完成永久坡道定位和支撑结构；在基坑挖掘期，进行按永久坡道坡度进行土方预留；永久坡道坡面上铺浇筑混凝土侧面拉锚索、布置钢筋网片并喷射细石混凝土；下层临时坡道与永久坡道相接；在开挖负二层过程中进行土方预留，预留的临时坡道土方侧面铺设钢筋网片并喷射细石混凝土，坡面铺设级配碎石并满铺钢板；在基坑整体挖掘完毕后，拆除临时坡道，依托第一步施工的永久坡道支撑结构进行永久坡道正式浇筑施工。
