Treatment process of buried drill slope protection pile supporting structure
The invention relates to a treatment process of a buried drill slope protection pile supporting structure. The treatment process comprises the following steps that S1, pile supplementing is conducted,specifically, a position supplementing pile is additionally driven behind a drill clamping slope protection pile; S2, crown beam construction is conducted, specifically, crown beam construction is conducted on the top of the slope protection pile, a supplementary crown beam is additionally arranged between a crown beam and the position supplementing pile, and the crown beam and the supplementarycrown beam form an inverted-T-shaped structure; S3, foundation pit excavation is conducted layer by layer, and a drill rod is dismantled, wherein the foundation pit is excavated in a layered mode, andprestressed anchor rod construction is conducted after excavation of each layer is completed; meanwhile, when the foundation pit is excavated, earthwork at the position of the drill clamping slope protection pile is excavated synchronously, and the drill rod is exposed and taken out; and S4, tensioning is conducted, specifically, a supporting beam is connected between a waist beam corresponding to the position supplementing pile and the position supplementing pile, and then anchor rod tensioning is conducted. The position supplementing pile is additionally driven behind the drill clamping slope protection pile to replace the slope protection pile, along with excavation of the foundation pit, the drill clamping slope protection pile can be hollowed out and the drill rod can be taken out, meanwhile, the waist beam is connected with the position supplementing pile through the supporting beam, so that the stability of the prestress anchor rod at the position supplementing pile is guaranteed.
本申请涉及一种埋钻护坡桩支护结构的处理工艺，包括以下步骤：S1、补桩：在卡钻护坡桩背后补打一根补位桩；S2、冠梁：进行护坡桩桩顶冠梁施工，并在冠梁和补位桩之间增设补充冠梁，冠梁与补充冠梁形成“凸”型结构；S3、基坑分层开挖并拆除钻杆：分层对基坑进行开挖，每层开挖完成后进行预应力锚杆施工；同时在开挖基坑时，同步将卡钻护坡桩处土方挖除，露出钻杆，将钻杆取出；S4、张拉：对应补位桩处的腰梁和补位桩之间连接支撑梁，然后进行锚杆张拉。在卡钻护坡桩后方补打补位桩，替代护坡桩，随着基坑的开挖，能够将卡钻护坡桩处挖空并取出钻杆，同时将腰梁通过支撑梁与补位桩连接，保证预应力锚杆在补位桩处的稳定性。
