Construction method of inter-pile slope protection for building foundation pit protection
The invention discloses a construction method of an inter-pile slope protection for building foundation pit protection, which comprises a grouting device, the grouting device comprises a grouting pipe, a wedge-shaped expansion head, a tail expansion device and a reinforcing connecting piece, and a plurality of grout overflow holes are formed in the grouting pipe; a connecting groove is formed in the slope protection pile, the reinforcing connecting piece is installed in the connecting groove through the switching fixing piece, the switching fixing piece comprises a Z-shaped supporting rod and a clamping piece, the clamping piece is connected with the reinforcing connecting piece, and one end of the Z-shaped supporting rod is installed on the slope protection pile; the construction method comprises the following steps that firstly, materials are prepared; step 2, jacking operation; step 3, structure connection; fourthly, a concrete surface layer is sprayed; and fifthly, high-pressure grouting is conducted. The grouting device is simple and compact in structure, the stability of a slope protection soil body is enhanced, the construction speed is increased, meanwhile, the anti-pressure ability of the whole structure is improved, connection is stable and reliable, the method is simple and efficient, the problem of collapse of soil between piles is solved, and the generalizability is high.
本发明公开了一种建筑基坑防护用桩间护坡的施工方法，包括注浆装置，该注浆装置包括注浆管、楔形扩充头、尾部扩大装置和加强连接件，在注浆管上设置有多个溢浆孔；在护坡桩上设有连接槽，加强连接件通过转接固定件安装在连接槽内，转接固定件包括Z形支撑杆和卡接件，卡接件与加强连接件相连，Z形支撑杆一端安装在护坡桩上；该施工方法包括以下步骤：步骤一，材料准备；步骤二，顶进作业；步骤三，结构连接；步骤四，喷射混凝土面层；步骤五，高压注浆。该注浆装置结构简单紧凑，增强了护坡土体的稳定性，提高了施工速度，同时也增加了整体结构的抗压能力，连接稳定可靠，该方法简单高效，解决了桩间土坍塌的问题，可推广性强。
