Construction method of super-large-span giant transfer beam
The invention discloses a construction method for a super-large-span giant transfer beam. The construction method comprises the steps that 1, earth excavation is conducted, and a cushion layer (2) below the transfer beam (1) is poured; 2, bottom brick blank films (31) are built on the two sides of the transfer beam; 3, a waterproof coiled material (4) is constructed on the cushion layer and is constructed to the top of the bottom brick blank film; 4, a transfer beam supporting frame (5) is placed on the cushion layer, and transfer beam steel bars (6) are bound; 5, the waterproof coiled materials are constructed to the transfer beam steel bars; 6, the brick blank film (3) is built; 7, backfilling earthwork (8); 8, a raft area cushion layer (9) is poured on the brick blank film and the earthwork, and the waterproof coiled material is constructed on the raft area cushion layer; and 9, raft reinforcing steel bars (10) are bound on the cushion layer in the raft area, concrete is poured, and the raft (11) and the transfer beam are synchronously poured into an integrated structure. The problems that in the prior art, during earthwork backfilling, a brick blank film is prone to collapse, and transfer beam steel bars in a narrow space are difficult to bind can be solved.
本发明公开了一种超大跨度的巨型转换梁施工方法，包括步骤：1：土方开挖并浇筑转换梁(1)下方的垫层(2)；2：在转换梁的两侧砌筑底部砖胎膜(31)；步骤3：再垫层上施工防水卷材(4)并施工至底部砖胎膜顶部；4：垫层上放置转换梁支撑架(5)，绑扎转换梁钢筋(6)；5：防水卷材施工至转换梁钢筋上；6：砌筑完成砖胎膜(3)；7：回填土方(8)；8：在砖胎膜和土方上浇筑筏板区域垫层(9)，防水卷材施工至筏板区域垫层上；9：在筏板区域垫层上绑扎筏板钢筋(10)并浇筑混凝土，筏板(11)和转换梁同步浇筑成一体结构。本发明能够解决现有技术中土方回填时砖胎膜易坍塌和狭窄空间内转换梁钢筋绑扎难度大的问题。
