Construction method for semi-circular pile of covered and excavated station
The invention discloses a construction method for a semi-circular pile of a covered and excavated station. The construction method for covering and digging the semicircular piles of the station comprises the following steps that pile position lofting is conducted on fender posts, and positioning holes are formed in the ground according to the structures of the fender posts; a reinforcement cage is prepared, and in the reinforcement cage, part of reinforcing steel bars protrude in the radial direction to form a semicircular reinforcement cage with an arc-shaped outline; bamboo plywood is arranged, and the bamboo plywood is connected to the semicircular rib cage; a reinforcement cage is put down to be inserted into the pile hole; concrete is poured into the reinforcement cage and solidified; arranging a top beam and a retaining wall, and excavating earth; and the bamboo plywood is dismantled to obtain the semicircular pile. In the whole construction process, only materials such as bamboo plywood and steel bars which are easy to purchase and low in price need to be input, so that the cost input is reduced, and the economical efficiency of the whole project is improved. Meanwhile, the bamboo plywood is easy to detach, noise is greatly reduced, the requirement for green construction is met, and the problems that semicircular pile construction is troublesome and engineering quality is difficult to guarantee are solved.
本发明公开了一种盖挖车站半圆桩的施工方法。该盖挖车站半圆桩的施工方法包括以下步骤：对围护桩进行桩位放样，根据围护桩的结构在地面上开设定位孔；制备钢筋笼，在钢筋笼中，部分钢筋沿径向凸出，以形成为具有圆弧形轮廓的半圆筋笼；设置竹胶板，竹胶板连接于半圆筋笼；下放钢筋笼，使其插设于桩孔中；将混凝土灌注至钢筋笼中，凝固；冠梁，设置挡土墙，土方开挖；拆除竹胶板，得到半圆桩。在整个施工过程中，仅需投入竹胶板、钢筋等易购、价低的材料，从而降低了成本投入，提高了整个项目的经济性。同时，因为竹胶板的拆除较为容易，同时极大程度减少了噪音，符合绿色施工要求，解决半圆桩施工麻烦且难以保证工程质量的问题。
