Large soft soil deep foundation pit reinforced concrete trestle construction method
The invention relates to a large soft soil deep foundation pit reinforced concrete trestle construction method. Hollow bags are arranged on the lower portions of latticed columns. A beam bottom cushion layer and a beam bottom isolation layer are arranged at the lower part of the upper-layer frame beam; a plate bottom cushion layer and a plate bottom isolation layer are arranged at the lower part of the trestle floor slab; a soil squeezing air bag is arranged at the front end of the material taking plate, and when the soil squeezing air bag squeezes a soil body, an inclined downward soil discharging acting force can be provided for the soil material through an inclined position adjusting body; a crushing hole and an expansion crushing body are arranged in the laitance section of the pile body, and a closed hoop plate belt is arranged on the periphery of the laitance section of the pile body; a protective air bag is arranged on the periphery of the lower-layer frame beam, and a lower supporting body and an upper supporting body are arranged between the lower-layer frame beam and the upper-layer frame beam; sliding beam rails are arranged on the outer sides of the lower-layer frame beams, and tarpaulin supporting beams and rainproof tarpaulin are arranged between the sliding beam rails which are opposite in a mirror image mode. The workload of chiseling away concrete in the latticed column can be effectively reduced, the efficiency of digging away soil in a pit is improved, and damage to the latticed column caused by breaking of concrete in a laitance section of a pile body is reduced.
本发明涉及一种大型软土深基坑钢筋混凝土栈桥施工方法，在格构柱的下部设置中空囊袋；在上层框梁下部设置梁底垫层和梁底隔离层；在栈桥楼板的下部设置板底垫层和板底隔离层；在取料板的前端设置挤土气囊，并可在挤土气囊挤压土体的同时，通过倾斜调位体对土料提供斜向下的排土作用力；在桩体浮浆段内设置破碎孔洞及膨胀破碎体，并在桩体浮浆段的外周设置封闭箍板带；在下层框梁的外周设置防护气囊，并在下层框梁与上层框梁之间设置下部支撑体和上部支撑体；在下层框梁外侧设置滑移梁轨，并在镜像相对的滑移梁轨之间设置篷布撑梁及防雨篷布。可有效减少格构柱内混凝土凿除工作量、提升坑内土体挖除效率、降低桩体浮浆段混凝土破碎对格构柱的损伤。
