Buffering pressure-resistant flow-stabilizing grouting device
The invention provides a buffering pressure-resistant flow-stabilizing grouting device which comprises a grouting pipe, an impeller fixing cavity is formed in the middle of the grouting pipe, a first small impeller, a large impeller and a second small impeller are sequentially fixed in the impeller fixing cavity in the direction from a grout inlet to a grout outlet of the grouting pipe, and the diameter of the first small impeller and the diameter of the second small impeller are the same as the radius of the large impeller. The first small impeller and the second small impeller rotate towards the slurry inlet of the grouting pipe, and the large impeller rotates towards the slurry outlet of the grouting pipe. The device can buffer, resist high pressure and continuously stabilize the grouting flow, balance of the interior of the grouting pressure and the interior of the grouting body is achieved, the structure principle is simple, practicability is high, cost is low, and the problems occurring in the grouting process of various permeable stratums can be effectively solved.
本发明提供一种缓冲耐压稳流注浆装置，包括注浆管，注浆管中部设置有一叶轮固定腔体，从注浆管进浆口到出浆口方向上，叶轮固定腔体中依次固定有第一小叶轮、大叶轮和第二小叶轮，第一小叶轮和第二小叶轮的直径与大叶轮半径相同，第一小叶轮和第二小叶轮均朝向注浆管进浆口方向转动，大叶轮朝向注浆管出浆口方向转动。本发明装置实现可缓冲、耐高压、持续稳定注浆流量，实现注浆压力内部与注浆体内部平衡，构造原理简单、实用性强、成本低，能有效解决各种透水地层注浆过程中出现的问题。
