Layered annular dense hole post-grouting construction structure for uplift-resistant and compression-resistant cast-in-place pile
The invention relates to the technical field of cast-in-place piles, and discloses an anti-pulling and anti-pressure cast-in-place pile layered annular dense hole post-grouting construction structure which comprises a pile body formed in a pile hole, a pile side soil body is arranged on the outer side of the pile body, a reinforcement cage is arranged in the pile body, and a pile bottom grouting pipe and a pile side grouting pipe are arranged on the reinforcement cage. The bottom of the pile bottom grouting pipe is higher than the bottom of the reinforcement cage, and a plurality of bottom grouting openings are formed in the pile bottom grouting pipe; the bottoms of the multiple pile side grouting pipes are sequentially arranged at intervals up and down in the axial direction of the reinforcement cage, the bottoms of the pile side grouting pipes are connected with annular grouting pipes correspondingly, the annular grouting pipes are arranged in the circumferential direction of the reinforcement cage in a surrounding mode, and multiple layered grouting openings are formed in the annular grouting pipes; a plurality of layered slurry layers formed by grouting of pile side grouting pipes are arranged on the periphery of the pile body, the layered slurry layers surround the periphery of the pile body and permeate into a pile side soil body, a pile bottom slurry layer formed by grouting of a pile bottom grouting pipe is arranged at the bottom of the pile body, and the pile bottom slurry layer permeates into a bearing layer.
本发明涉及灌注桩的技术领域，公开了抗拔抗压灌注桩分层环形密集孔后注浆施工结构，包括形成在桩孔中的桩体，桩体的外侧具有桩侧土体，桩体中具有钢筋笼，钢筋笼上设有桩底注浆管以及桩侧注浆管，桩底注浆管的底部高于钢筋笼的底部，桩底注浆管上设有多个底部注浆口；多个桩侧注浆管的底部沿着钢筋笼的轴向依序上下间隔布置，桩侧注浆管的底部分别连接有环形注浆管，环形注浆管沿着钢筋笼的周向环绕布置，环形注浆管上设有多个分层注浆口；桩体的外周具有多个由桩侧注浆管注浆形成的分层浆层，分层浆层环绕在桩体的外周，且渗入至桩侧土体中，桩体的底部具有有桩底注浆管注浆形成的桩底浆层，桩底浆层渗入至持力层中。
