Auxiliary precipitation treatment construction method for deep foundation local sump foundation trench caisson
A deep foundation local sump foundation trench caisson auxiliary precipitation treatment construction method comprises the following steps that firstly, pit bottom treatment is conducted, specifically, the pit bottom elevation is controlled, meanwhile, the pit bottom is excavated, and manual trench cleaning, leveling and slope repairing are conducted; a plurality of steel plates are welded into a trapezoidal structure with an opening in the top, two layers of steel bars are arranged in the caisson, anti-skid steel bars are welded to the outer side of the caisson, and horizontal ribs are welded to the outer side of the caisson; compared with the prior art, on the premise of ensuring uniform and stable stress, the construction operation difficulty is reduced, the construction efficiency is improved, the construction period is shortened, in addition, slurry is poured on the outer side of the caisson, meanwhile, concrete is poured in the caisson, the caisson is in complete contact with the side wall of the sump, the caisson fixing effect is achieved, and the service life of the caisson is prolonged. And meanwhile, the three-way water diversion device is adopted for treating leakage points, and the problems that underground water in the sump foundation trench upwells and accumulates water are thoroughly solved.
一种深基础局部集水坑基槽沉箱辅助降水处理施工工法，包括以下步骤：步骤一、坑底处理：对坑底标高进行控制，同时对坑底进行开挖，并进行人工清槽、平整及修坡；步骤二、沉箱制作：将若干钢板焊接成顶部开口的梯形结构，并在沉箱内设置两层钢筋，在沉箱的外侧焊接防滑钢筋，并且在沉箱外侧焊接水平肋；与现有技术相比，可在确保受力均匀稳定的前提下，降低了施工操作难度，提高了施工效率，缩短了施工周期，另外在沉箱外侧灌注浆料，同时在沉箱内浇筑混凝土，使沉箱与集水坑侧壁完全接触，起到了沉箱的固定作用，有效地减少了地下水从基槽侧壁涌入基槽内，同时采用三向引水装置对渗漏点进行处理，彻底解决集水坑基槽地下水上涌以及积水问题。
