Mass concrete construction process for effectively preventing concrete temperature shrinkage cracks
The invention discloses a mass concrete construction process capable of effectively preventing concrete temperature shrinkage cracks, which comprises the following steps: before pouring platform body concrete, arranging cooling pipes in the platform body, welding the cooling pipes at the corners by elbows, arranging two layers of vertical cooling pipes on the platform body, locally arranging three layers of vertical cooling pipes on the platform body, arranging one row of vertical cooling pipes every 5 meters in the transverse direction, and arranging a water inlet and a water outlet on each layer of cooling pipes, all the components are arranged on the platform body; interlayer water inlets and interlayer water outlets are respectively independent, valves are arranged at the water inlets to control the flow of cooling water so as to correspondingly adjust the water circulation speed and the water inlet temperature of each layer according to temperature measurement data, the cooling pipes are erected in the platform body by adopting reinforcing steel bars and firmly bound by iron wires, a bleeding test is carried out on the cooling pipes after installation is completed, and no blockage and no water leakage are ensured. The problem of cracks can be effectively solved.
本发明公开了一种有效防制混凝土温缩裂缝的大体积混凝土施工工艺，包括：台身混凝土浇筑前，在其内部布设冷却管，对于拐弯处冷却管以弯头焊接，台身竖向冷却管共设2层、局部为3层，横向每5米设置一排，每层冷却管设进水口、出水口各一处，均设在台身上面；层间进水口、出水口各自独立，在进水口设阀门以控制冷却水流量，以便根据测温数据，相应调整各层水循环速度和进水温度，冷却管在台身中采用钢筋架立并以铁丝帮扎牢固，安装完毕后要对其进行泌水试验，确保不堵塞、不漏水。本发明能有效解决裂缝问题的出现。
