Underground diaphragm wall construction process and construction equipment
The invention discloses an underground diaphragm wall construction process and construction equipment. The underground diaphragm wall construction process comprises the following steps: a grooving step: machining an underground groove to a preset depth at a preset construction position through grooving equipment of a composite pile machine; the prefabricated pile walls which are continuously spliced in the transverse direction and/or the longitudinal direction are inserted into the underground groove through pile sinking equipment of the composite pile machine, and the insertion depth of the prefabricated pile walls is 1.01-1.5 times of the depth of the underground groove. The underground diaphragm wall is formed by inserting the precast pile walls in the underground groove, the precast pile walls are inserted, so that the parts, located at the lower end of the underground groove, of the precast pile walls are clamped, the precast pile walls are not prone to toppling towards one side of the thickness direction, the adjacent precast pile walls can be approximately on the same horizontal line in the transverse direction, and butt joint between the adjacent precast pile walls is facilitated; and the integrity and the sealing performance of the underground diaphragm wall are further guaranteed, so that the water seepage phenomenon of the underground diaphragm wall is avoided. And after insertion is completed, the perpendicularity of the prefabricated pile wall does not need to be adjusted, and the construction time and cost of the underground diaphragm wall are saved.
本发明公开了地下连续墙施工工艺及施工设备，包括：成槽步骤：在预定施工位置通过复合桩机的成槽设备加工地下槽至预定深度；插桩步骤：通过复合桩机的沉桩设备在地下槽内插设横向和/或纵向连续拼接的预制桩墙，并使得预制桩墙的插设深度为地下槽深度的1.01～1.5倍。通过在地下槽内插设预制桩墙以形成地下连续墙，插设预制桩墙，使得预制桩墙位于地下槽下端的部分被夹持，预制桩墙不易往厚度方向一侧倾倒，相邻预制桩墙在横向上能大致同一水平线上，便于相邻预制桩墙之间的对接，进一步保证了地下连续墙的整体性和密封性，以避免地下连续墙出现渗水现象。并且插设完成后，无需对预制桩墙垂直度进行调整，节约地下连续墙的施工时间与成本。
