Foundation pit support equipment for bridge foundation construction
The invention relates to the technical field of foundation pit support equipment, and discloses foundation pit support equipment for bridge foundation construction, which comprises a soil nail and a soil nail kit sleeving the outer side of the soil nail, the soil nail kit comprises a main sleeve and a positioning cylinder, the positioning cylinder is located at one end of the main sleeve, and the positioning cylinder is located at the other end of the main sleeve. The positioning cylinder is arranged in the main sleeve, the positioning cylinder and the main sleeve are in threaded connection through threads, a plurality of movable blocking pieces are arranged in the positioning cylinder, fixing grooves are formed in the positioning cylinder, the positions and the number of the fixing grooves correspond to those of the movable blocking pieces in a one-to-one mode, and a connecting convex rib is arranged at the end, away from the main sleeve, of the positioning cylinder. According to the method, drilling in advance is not needed, the construction speed is effectively increased, after concrete filling, concrete can wrap the soil nail, the anti-corrosion effect is good, and the service life of the soil nail is effectively prolonged.
本发明涉及基坑围护设备技术领域，且公开了一种用于桥梁基础施工的基坑围护设备，包括土钉和套设在土钉外侧的土钉套件，所述土钉套件包括主套筒和定位筒，所述定位筒位于所述主套筒的一端，且所述定位筒与所述主套筒之间通过螺纹螺接，所述定位筒内设有若干个活动挡片，且所述定位筒上设有位置和数量与所述活动挡片一一对应的固定槽，所述定位筒远离所述主套筒的一端设有连接凸筋。本发明无需提前打洞，有效的提高了施工速度，而且在灌装混凝土后，混凝土可将土钉包裹起来，抗腐蚀效果好，有效的延长了土钉的使用寿命。
