Bottom-communicated pile foundation sounding pipe structure and construction method for preventing sounding pipe from being blocked
The invention provides a bottom-communicated pile foundation sounding pipe structure and a construction method for preventing a sounding pipe from being blocked. The sounding pipe structure is composed of sounding pipes and a communicating pipe, wherein the communicating pipe is circular and is positioned at the bottom of a pile foundation, and the bottom end of each sounding pipe is communicatedwith the communicating pipe. By adopting the bottom-communicated pile foundation sounding pipe structure in pile foundation ultrasonic detection, water can be simultaneously injected into all the sounding pipes at a time, water injection in the sounding pipe lowering process is facilitated, whether water leakage occurs at the connecting positions of the sounding pipes or not can be detected, timely treatment can be performed, water pressure inside and outside the sounding pipes can be also balanced, mud permeation can be prevented, mud impurities entering the sounding pipes can be discharged through continuous water injection after the sounding pipes are lowered, and pipe blockage can be avoided. Furthermore, in the concrete pouring process, water in the sounding pipes is kept circulatingtill concrete is finally set, cement paste possibly permeating into the sounding pipes can be diluted and discharged, and pipe blockage can be prevented. The bottom-communicated pile foundation sounding pipe structure is simple and convenient to construct and has good technical and economic benefits.
底部连通式桩基声测管构造及防止声测管堵管的施工方法，该声测管构造由声测管和连通管组成，连通管为圆环形，位于桩基底部，各声测管底端与连通管相连通。在桩基超声检测中采用本发明，可以实现一次性向所有声测管内同时注水，方便在声测管下放过程中注水，可以检测声测管连接处是否漏水，以及时进行处理，还可以平衡声测管内外的水压力，防止泥浆渗入，并且通过在声测管下放完成后持续注水可以将声测管内进入的泥浆杂物排出，避免造成堵管。进一步，在混凝土浇筑过程中，保持声测管内的水循环至混凝土终凝，可以稀释和排出可能渗入声测管内的水泥浆，防止发生堵管。本发明构造简单，施工方便，具有良好的技术经济效益。
