Construction method for tower crane foundation in deep and thick mucky layer
The invention provides a deep mucky layer tower crane foundation construction method, and relates to the technical field of slope engineering, the deep mucky layer tower crane foundation construction method comprises the steps of surveying and setting out, prestressed pipe pile construction, reinforced concrete bearing platform construction, steel sheet pile construction, arrangement of a steel enclosing purlin, filling of a gap between the steel sheet pile and the reinforced concrete bearing platform with stone powder, filling of cement paste after filling, and construction of a foundation. The load of the tower crane is evenly distributed to the prestressed pipe piles below by arranging the reinforced concrete bearing platform, vertical force is evenly transmitted to the lower granite layer through the prestressed pipe piles, meanwhile, a circle of 18m long steel plate piles are constructed around the reinforced concrete bearing platform in a closed mode, and I-shaped steel surrounding purlins are arranged; and cement paste stone powder is filled between the steel sheet piles and the pipe piles, so that an integral vertical foundation is formed below the bearing platform, the vertical bearing capacity is improved, the bending resistance, torsion resistance and shearing resistance of the foundation are improved, and the stability of the tower crane foundation is effectively improved.
本申请提供了一种深厚淤泥质层塔吊基础施工方法，涉及边坡工程技术领域，测量放线、预应力管桩施工、钢筋混凝土承台施工、钢板桩施工、设置钢围檩，钢板桩与钢筋混凝土承台之间的缝隙采用石粉填筑，填筑完成后加注水泥浆，本申请通过设置钢筋混凝土承台将塔吊的荷载均匀分配给下方预应力管桩，通过预应力管桩将竖向力均匀传递至下层花岗岩层上，同时，围绕钢筋混凝土承台周围封闭施打一圈18m长钢板桩并设置工字钢围檩，并在钢板桩与管桩间填充水泥浆石粉，使承台以下形成一个整体的竖向基础，不仅提高了竖向承载力，同时提高了基础抗弯折、抗扭力、抗剪力，有效提高塔吊基础的稳定性。
