Casing pipe construction equipment for all casing pipe secant pile and method using same
The invention discloses casing pipe construction equipment for an all casing pipe secant pile and a method using the same. The equipment comprises an inner sleeve, an outer sleeve, a connecting bearing, excavator buckets, a slag hole valve, a limiting strip and cutting teeth, wherein the cutting teeth are welded to the lowermost end of the inner sleeve, the outer sleeve is connected with the innersleeve through the connecting bearing, the connecting bearing is composed of an upper bottom ring, a lower bottom ring and a shaft ring, the upper bottom ring and the lower bottom ring are welded tothe outer wall of the inner sleeve, the shaft ring is welded to the inner wall of the outer sleeve, the four excavator buckets are symmetrically welded to the outer side of the outer sleeve, slag holes are correspondingly formed in the positions, at the top height of the buckets, of the outer sleeve and the inner sleeve, the slag hole valve is arranged on the inner side of the slag hole of the outer sleeve, and the limiting strips are welded to the upper edge and the lower edge of the slag hole of the inner sleeve. According to the casing pipe construction equipment of the all casing pipe secant pile and the method using the same, when the sleeves are used for cutting a plain concrete pile during secant pile construction, two secant grooves are cut in a traditional arc-shaped secant surface through the excavator buckets, the contact area between the reinforced concrete pile and the plain concrete pile is increased, the leakproofness of the secant position is improved, and therefore theimpermeability of the secant surface position of the secant pile is improved.
本发明公开了一种全套管咬合桩的套管施工设备及其方法。该设备包括内套管、外套管、连接轴承、挖斗、出渣口活门、限位条、削切齿；在内套管最下端焊接有削切齿，外套管通过连接轴承与内套管相连接，连接轴承由上底圈、下底圈和轴圈构成，上底圈和下底圈焊接在内套管的外壁，轴圈焊接在外套管的内壁，外套管外侧对称焊接有4个挖斗，外套管和内套管在挖斗顶部高度分别开设有出渣口，外套管出渣口内侧布置有出渣口活门，限位条焊接在内套管出渣口上下边缘。本发明在咬合桩施工使用套管切割素混凝土桩时，通过挖斗在传统圆弧形的咬合面切割出两处咬合槽，增大钢筋混凝土桩和素混凝土桩间的接触面积，提高咬合处的密闭性，从而提高咬合桩咬合面处的抗渗性。
