Cast-in-situ bored pile deep foundation pit supporting structure and using method
The invention discloses a cast-in-situ bored pile deep foundation pit supporting structure which comprises an ejector rod and two supporting frames, the supporting frames are arranged on the two sides of the ejector rod, limiting grooves used in cooperation with the supporting frames are formed in the side, close to the supporting frames, of the ejector rod, movable grooves are formed in the two sides of the ejector rod, and fixing mechanisms are arranged in inner cavities of the movable grooves. A control mechanism used in cooperation with the fixing mechanism is arranged on the front side of an inner cavity of the movable groove. Through cooperative use of a fixing mechanism, a control mechanism and a first through hole, a pull rod is rotated, the pull rod drives a rotating rod to rotate, meanwhile, the rotating rod drives a fixing column to enter an inner cavity of a movable groove through a rotating plate and extrudes a spring, a user puts an ejector rod on the supporting frame, and the problems that an existing supporting frame is inconvenient to fix the ejector rod, and the supporting frame is inconvenient to use are solved. And the problem that the use of the supporting plate is influenced by the change of the supporting position due to the fact that the jacking rod is very easy to jack up and displace in use is solved.
本发明公开了一种钻孔灌注桩深基坑支护结构，包括顶杆和两个支护架，所述支护架设置于顶杆的两侧，所述顶杆靠近支护架的一侧开设有与支护架配合使用的限位槽，所述顶杆的两侧均开设有活动槽，所述活动槽的内腔设置有固定机构，所述活动槽内腔的前侧设置有与固定机构配合使用的控制机构。通过设置固定机构、控制机构和第一通孔的配合使用，转动拉杆，拉杆带动转动杆转动的同时，转动杆通过转动板带动固定柱进入活动槽的内腔并挤压弹簧，使用者将顶杆放在支护架上，解决了现有支护架不便于对顶杆进行固定，顶杆在使用中十分容易被顶起和位移，导致顶撑位置发生改变，影响对支护板进行使用的问题。
