Piling protection method for static pressure piles around shallow foundation building
The invention relates to the field of engineering construction, and particularly discloses a piling protection method for static pressure piles around a shallow foundation building. The piling protection method comprises the following steps of (1) digging a groove between a static pressure pile area and the shallow foundation building, wherein the depth of the groove is 8 to 12 m; (2) laying protective nets on both side walls of the groove, wherein the protective nets are made of heat conduction materials and completely cover the side walls of the groove; (3) backfilling the groove with stonestill the stones are flush with the top of the groove; (4) heating the protective nets to the temperature higher than the melting temperature of an asphalt composition, and injecting the hot-melt asphalt composition into the groove so as to fill gaps between the stones; (5) compacting the top of the groove after the groove is filled with the asphalt composition; and (6) stopping heating the protective nets, standing and cooling for 72 hours or above, and then performing static pile driving operation. The piling protection method has the advantages that the soil structure of the area in which the protective structure is located during static pile construction can be restored, and the limitation on later-period application of the area is reduced.
本申请涉及工程施工领域，具体公开了一种浅基础建筑周边静压桩打桩防护方法。包括以下步骤：步骤1），在静压桩区域与浅基础建筑之间开挖沟槽，所述沟槽深度为8‑12米；步骤2），沟槽两侧壁上铺设防护网，所述防护网由导热材料制成并完全覆盖沟槽侧壁；步骤3），沟槽内回填石块至与沟槽顶部平齐；步骤4），加热防护网至沥青组合物熔融温度以上，向沟槽内注入热熔的沥青组合物以填充石块间隙；步骤5），待沥青组合物填满沟槽后，压实沟槽顶部；步骤6），停止防护网加热，静置冷却72小时或以上，即可进行静压桩打桩作业。其具有可恢复静压桩施工时防护结构所在区域的土壤结构，减少对该区域的后期用途的限制的优点。
