Construction method of h-shaped pile
The invention discloses an h-shaped pile construction method, which relates to the field of civil engineering or geotechnical engineering, and comprises the following steps: normally constructing front-row short piles, reserving a plurality of first cross beam connecting steel bars at the tops of the piles, and enabling the end parts of the plurality of first cross beam connecting steel bars to extend out of the front-row short piles; rear-row pile holes are constructed, a steel retaining wall with holes is arranged on a cross beam section, and a plurality of preformed holes are formed in one side of the steel retaining wall with the holes; a plurality of second cross beam connecting steel bars are arranged in the perforated steel retaining wall and extend out of the preformed holes; placing a reinforcement cage in the rear-row pile holes, connecting a plurality of second cross beams with reinforcements and pile main reinforcements, and pouring pile body concrete; a cross beam foundation pit is excavated, cross beam main reinforcements and cross beam connecting reinforcements are lapped and bound, and then cross beam concrete is poured; and finally backfilling the foundation pit. A single-face perforated steel retaining wall is arranged in a rear pile hole, an embedded steel bar is connected with a rear pile main bar, a cross beam foundation pit is excavated to expose the embedded steel bar and then is effectively connected with a cross beam main bar, concrete is cast in place, and rigid effective connection of a cross beam and a rear pile is achieved.
本发明公开了一种h型桩施工方法，涉及土木工程或岩土工程领域，包括以下步骤：前排短桩按正常施工，并在桩顶预留若干第一横梁连接钢筋，若干第一横梁连接钢筋端部均伸出前排短桩；施工后排桩孔，横梁段设置带孔钢护壁，带孔钢护壁一侧带有若干预留孔；在带孔钢护壁内设置若干第二横梁连接钢筋，并伸出预留孔；在后排桩孔处下钢筋笼，将若干第二横梁连接钢筋和桩主筋，并浇筑桩身混凝土；开挖横梁基坑，并将横梁主筋和横梁连接钢筋搭接绑扎，随后浇筑横梁混凝土；最后回填基坑。采用后桩桩孔内设置单面带孔钢护壁，预埋钢筋与后桩主筋连接，横梁基坑开挖暴露预埋钢筋后与横梁主筋有效连接并现浇混凝土，实现横梁与后桩的刚性有效连接。
