Abstract

一种将排水板送入地下并可拔出排水板前圆钢 的钢管装置,现技术处理软土地基时,需将几万根圆 钢随排水板留在地下、浪费了大量钢材。本实用新型 包括前端有尖口的钢管和能遮住钢管前端开口的圆 钢,钢管前端设有壁眼,圆钢一端也设有壁眼,钢管壁 眼与圆钢壁眼之间用软绳连接。软绳是钢丝绳。由 于采取了本装置,在拔钢管时,将圆钢一起拉出,排水 板留在地下,这样就节约了大量圆钢,降低了施工成 本。
The utility model relates to a steel tube unit with pullable steel bar in front of drainage board. When the prior art is used to treat the soft foundation, ten thousands of steel bars are left under the ground with the draining board, and a plurality of steel is wasted. The front end of the steel tube is provided with a wall eye, one end of the steel bar is also provided with a wall eye, and the wall eye of the steel tube is connected with the wall eye of the steel bar by a soft rope. The soft rope is wire rope. Because the utility model is adopted, the steel bar is pulled out together with the steel tube when the steel tube is pulled out, the draining board is left under the ground, a plurality of steel bars are saved, and construction cost is reduced.
