Grouting guide pipe and construction method thereof
The invention provides a grouting guide pipe and a construction method thereof, and the grouting guide pipe comprises a first guide pipe, wherein the first end is a pointed end; a second guide pipe, the first end of the second guide pipe is in threaded connection with the second end of the first guide pipe; hollow sliding blocks, the two hollow sliding blocks are arranged on the first guide pipe and the second guide pipe in a sliding and sleeving mode respectively, the two ends of the hollow sliding block on the first guide pipe are limited, and the end, away from the first guide pipe, of the hollow sliding block on the second guide pipe is limited; expansion devices which are hinged to the hollow sliding blocks on the first guide pipe and the second guide pipe respectively, and the second guide pipe is screwed into the second guide pipe relative to the first guide pipe in a threaded mode, so that the expansion devices expand in the circumferential direction of all the guide pipes; grouting holes are formed in the circumferential walls of the first guide pipe and the second guide pipe, and grouting is conducted through the second end of the second guide pipe. According to the grouting guide pipe and the construction method thereof, the grout enters the broken rock stratum through pouring, a consolidation body high in strength and good in waterproof performance is formed, and the stability of the rock stratum is greatly improved.
本申请提供种注浆导管及其施工方法，注浆导管包括：第一导管，其第一端为尖头端；第二导管，其第一端螺纹连接于第一导管的第二端上；空心滑块，两个空心滑块分别滑动套设在第一导管和第二导管上，第一导管上的空心滑块两端限位，第二导管上的空心滑块背离第一导管的方向一端限位；扩张装置，其分别铰接在第一导管和第二导管上的空心滑块上，通过第二导管相对第一导管螺纹旋进第二导管，使得扩张装置在各导管的周向扩张；其中，第一导管和第二导管的周壁上均开设有注浆孔，通过第二导管的第二端注浆。本申请提供的注浆导管及其施工方法，通过浇筑，浆液进入到破碎的岩层中，形成强度高、防水性能好的固结体，大幅度的提高了岩层的稳定性。
