Sunken elevator shaft of reconstructed community under sandbar geology and construction method of sunken elevator shaft
The invention discloses a sunken elevator shaft for a reconstructed community under the sandbar geology and a construction method of the sunken elevator shaft. The sunken elevator shaft comprises cement mixing piles, cast-in-place piles, a top beam, a base structure, an intercepting ditch, an elevator shaft body, an embedded part and a water pump. The cement mixing piles are divided into bottom sealing piles, inner piles, separation piles and outer piles according to different positions; the cast-in-place piles are arranged around the foundation pit; the top beams connect the top ends of all the cast-in-place piles; the base structure comprises bottom sealing concrete, a water collecting pit, a reinforcing mesh, a leveling layer and a waterproof layer. The intercepting ditch is arranged around the outer side of the outer pile; the elevator shaft is of an integrated ear cap structure and comprises a pool body and a ring beam plate, and the ring beam plate is of an inner buckling top structure. The embedded part is embedded in the top beam and is used for mounting a steel framework of a ground elevator passage; the water pump is mounted in the water collecting pit and connected to the intercepting ditch. The influence of foundation pit excavation and supporting structure construction on surrounding structures is reduced, dry construction is achieved, foundation bearing capacity can be provided for elevator installation, and the anti-floating and water stopping effects can be guaranteed.
本发明公开一种沙洲地质下改建小区下沉式电梯井及其施工方法，该下沉式电梯井包括水泥搅拌桩、灌注桩、冠梁、基底结构、截水沟、电梯井、预埋件和水泵；水泥搅拌桩按不同位置分为封底桩、内桩、分隔桩和外桩；灌注桩排布在基坑四周；冠梁将所有灌注桩顶端连接；基底结构包括封底混凝土、集水坑、钢筋网、找平层、防水层；截水沟设在外桩外侧四周；电梯井采用一体式耳帽结构，包括池体和圈梁板，圈梁板采用内扣压顶结构；预埋件埋设在冠梁内，用于安装地面电梯通道的钢骨架；水泵安装在集水坑内且连接至截水沟。本发明降低了基坑开挖和支护结构的施工对周边构筑物的影响，实现了干法施工，能为安装电梯提供地基承载力，能保证抗浮和止水效果。
