Frame plate type side slope foundation pit connecting structure and adjacent foundation pit side slope supporting method
The invention relates to the technical field of slope construction, and discloses a method for supporting a slope near a foundation pit, which comprises the following steps: S1, surveying and setting out; s2, a side slope is excavated, anchor rods are constructed in the side slope, concrete is sprayed to the excavated face, a steel wire mesh is hung after maintenance is conducted to the designed strength, and concrete is sprayed again to cover the steel wire mesh; s3, the step S2 is repeated until the top elevation of the foundation pit is excavated; s4, supporting piles, top beams and anchor cables are constructed, tensioning and locking are conducted after maintenance is conducted to the designed strength, and foundation pit excavation is started; s5, the step S4 is repeated until the pit bottom is excavated; s6, a basement structure is constructed in the foundation pit, and the foundation pit is backfilled; and S7, the rear baffle, the bottom plate, the front baffle, the middle shelf and the top plate are subjected to formwork construction, and a frame plate type supporting structure is formed. According to the embodiment of the invention, the temporary foundation pit and the permanent side slope can be mutually combined through the frame plate type supporting and retaining structure of the side slope near the top of the foundation pit, and the construction quality of the side slope and the foundation pit is effectively guaranteed.
本发明涉及边坡施工技术领域，公开了一种临基坑边坡支护方法,包括以下步骤：S1、测量放线；S2、开挖边坡，向边坡内施作锚杆并对开挖面喷射混凝土，养护至设计强度后挂设钢丝网，再次喷射混凝土覆盖钢丝网；S3、重复步骤S2直至开挖至基坑顶部标高；S4、施工支护桩、冠梁和锚索，养护至设计强度后张拉锁定，开始开挖基坑；S5、重复步骤S4直至开挖至坑底；S6、在基坑内施工地下室结构，回填基坑；S7、支模施工后挡板、底板、前挡板、中部搁板和顶板，形成框板式支挡结构。本发明实施例通过临基坑顶部边坡的框板式支挡结构，能够使得临时基坑和永久边坡的相互结合，有效保证边坡和基坑的施工质量。
