Construction method for achieving fast traffic beveling and dismantling temporary stand column through temporary buttress
The invention discloses a construction method for realizing rapid traffic beveling and dismantling a temporary stand column by adopting a temporary buttress, which comprises the following steps of: constructing an underground diaphragm wall, forming retaining walls on two sides in a subway station, and dividing the space between the retaining walls on the two sides into two stages in the width direction; temporary stand column piles are built at intervals in the length direction of the retaining wall in the position between the two periods; early-stage roads are laid at the top positions of the two stages, and a soil outlet is reserved corresponding to the position of one stage; a structural top plate is laid between the retaining walls on the two sides and close to the top; constructing the subway station layer by layer from top to bottom; wall sealing treatment is conducted on the position, corresponding to the soil outlet hole, of the structural top plate, backfilling is conducted on the first-stage position corresponding to the soil outlet hole, and a later-stage road is laid; and the early-stage road and the temporary stand column piles are dismantled, wall sealing treatment is conducted on the corresponding hole positions of the structural top plate, first-stage positions corresponding to the holes are backfilled, and a later-stage road is laid. In the construction process of the subway station without the stand columns, the traffic obstruction degree of the position where the subway station is located can be reduced.
本发明公开了一种采用临时支墩实现快速交通倒边及拆除临时立柱施工方法,其包括：地下连续墙施工，形成地铁站内两侧的挡墙，将两侧的挡墙之间的宽度方向上分为两期；在两期之间位置朝挡墙的长度方向间隔建筑临时立柱桩；两期的顶部位置均铺设前期道路，对应其中一期位置预留出土口；在两侧的挡墙之间靠近顶部位置铺设结构顶板；自上而下逐层对地铁站进行施工；结构顶板对应出土孔位置进行封墙处理，出土孔对应的一期位置进行回填且铺设后期道路；拆除前期道路和临时立柱桩，结构顶板对应孔洞位置进行封墙处理，孔洞对应的一期位置进行回填且铺设后期道路。本申请具有在建设无立柱地铁站的过程中，可降低地铁站所处位置的交通阻碍程度。
