Cast-in-place pile end core-pulling sediment detection device
The invention discloses a cast-in-place pile end core-pulling sediment detection device which comprises a cast-in-place pile reinforcement cage, a first grouting pipe, a second grouting pipe and a third grouting pipe. The first grouting pipe, the second grouting pipe and the third grouting pipe are bound and fixed on the inner wall of the cast-in-place pile reinforcement cage through stirrups, theend of the first grouting pipe, the end of the second grouting pipe and the end of the third grouting pipe are connected with a wooden plug check valve, a metal check valve and a rubber check valve through screw threads correspondingly, the wooden plug check valve is composed of a steel pipe and a wooden plug inserted into the steel pipe, one end of the metal check valve is provided with a connecting thread, the other end of the metal check valve is provided with a duckbill-shaped steel pipe, the rubber check valve comprises a steel pipe with the end provided with the connecting thread and arubber wrapping layer, the steel pipe is wrapped by the rubber wrapping layer, and rust-proof steel wires are wound at the two ends of the rubber wrapping layer. According to the cast-in-place pile end core-pulling sediment detection device, the two procedures of pile bottom sediment detection and pile bottom soil reinforcement are fused together, a series of steps such as drilling and coring of traditional pile bottom sediment detection are omitted, the construction period is shortened, and the construction cost is reduced.
本发明公开了一种灌注桩桩端抽芯沉渣检测装置，包括灌注桩钢筋笼、第一注浆管、第二注浆管和第三注浆管，第一注浆管、第二注浆管和第三注浆管通过箍筋绑扎固定于灌注桩钢筋笼的内壁上，第一注浆管、第二注浆管和第三注浆管的端部分别通过丝扣连接有木塞止回阀、金属止回阀和橡胶止回阀，木塞止回阀由钢管和插入钢管的木塞组成，金属止回阀为一端设有连接螺纹且另一端呈鸭嘴状的钢管，橡胶止回阀包括端部设有连接螺纹的钢管和橡胶包裹层，橡胶包裹层包覆于钢管上，橡胶包裹层的两端缠绕有防锈钢丝。本装置将桩底沉渣检测与桩底土体加固两道工序融合在一起，减少传统的桩底沉渣检测的钻孔取芯等一系列步骤，降低了施工工期以及工程造价。
