Foundation pit support and foundation pit support method
The invention relates to a foundation pit support. The foundation pit support comprises a foundation pit enclosing purlin; an inner support; the counter-pull supporting structure is arranged on a part of or all the sections, not supported by the inner supports, of the foundation pit enclosing purlin, and the counter-pull supporting structure comprises an anchoring bearing platform, a plurality of protection plates, a plurality of anchorage devices and a plurality of steel ropes; the anchoring bearing platform is arranged in an earthwork structure on the outer side of a foundation pit in a piling mode. The protection plates correspond to the steel ropes one to one, the protection plates are arranged on the side, facing the interior of the foundation pit, of the foundation pit surrounding purlin at intervals, one ends of the steel ropes penetrate through the foundation pit surrounding purlin and are connected with the protection plates through anchorage devices, and the other ends of the steel ropes are connected with the anchoring bearing platform through anchorage devices. And the steel rope is tightened between the protective plate and the anchoring bearing platform. The counter-pull supporting structure can control deformation of parts such as external corners of the foundation pit where inner supports cannot be arranged, can be installed during foundation pit enclosing purlin construction, can play a supporting role before excavation of the foundation pit, and basically does not damage an earthwork structure on the outer side of the foundation pit.
本发明涉及一种基坑支护，其包括：基坑围檩；内支撑；反拉支护结构，设置在部分或全部所述基坑围檩未被内支撑支护的节段，所述反拉支护结构包括锚固承台、若干护板、若干锚具以及若干钢绳；所述锚固承台打桩设置在基坑外侧的土方结构中；所述护板与钢绳一一对应，所述护板间隔设置在基坑围檩朝向基坑内部的一侧，所述钢绳的一端穿过基坑围檩并通过锚具连接护板，所述钢绳的另一端则通过锚具连接锚固承台；所述钢绳绷紧于护板和锚固承台之间。本发明反拉支护结构可以控制基坑阳角等无法设置内支撑的部位的变形，其在基坑围檩施工时即可安装，可以在基坑开挖前就起到支护作用，而且基本不会破坏基坑外侧的土方结构。
