Steel flower tube pile enclosure structure suitable for upper-soft lower-hard stratum and construction method
The invention provides a steel flower tube pile enclosure structure suitable for an upper-soft lower-hard stratum. The steel flower tube pile enclosure structure comprises a top beam. high-pressure jet grouting piles are arranged along the top beam in an overlapping mode, and steel flower tubes are arranged in the high-pressure jet grouting piles; a steel reinforcement cage is inserted into each steel flower tube and comprises steel flower tube inner insertion main reinforcements which are vertically arranged along the steel flower tube and steel flower tube inner insertion stirrups which are arranged perpendicular to the steel flower tube; the tops of the steel flower tubes extend into the top beam, and the steel flower tubes, the top beam stirrups and tie bars are arranged on a plane in a staggered manner; the steel flower tube inner insertion main reinforcements extend out of the steel flower tubes and are bent towards the horizontal direction at the tops of the steel flower tubes; the steel flower tube inner insertion main reinforcements which are horizontally bent on the adjacent steel flower tubes are mutually welded and connected and are mutually vertically staggered on horizontal bending planes; and the horizontal bending planes of the steel flower tube inner insertion main reinforcements are positioned in the top beam. On the basis of ensuring the strength and rigidity of the enclosure structure, the structure has the advantages of low comprehensive manufacturing cost, small occupied space and the like.
本发明提供一种适用于上软下硬地层的钢花管桩围护结构，包括冠梁；沿冠梁交叠设置有高压旋喷桩，所述高压旋喷桩内设有钢花管；所述钢花管内插有钢筋笼，所述钢筋笼包括沿钢花管竖向设置的钢花管内插主筋和与钢花管垂直设置的钢花管内插箍筋；钢花管顶部伸入冠梁内，且钢花管与冠梁箍筋及拉筋在平面上交错布置；钢花管内插主筋伸出钢花管并在钢花管顶部向水平方向弯折，相邻钢花管上水平弯折的钢花管内插主筋相互焊接连接，并在水平弯折的平面上相互垂直交错布置，钢花管内插主筋的水平弯折的平面位于冠梁内。本发明在保证围护结构强度及刚度基础上，具有综合造价低，占用空间小等优势。
