Multi-functional casing pipe part and anchor rod construction method using same

Abstract

The invention relates to a multi-functional casing pipe part and aims at providing a multi-functional casing pipe part which is simple in structure, easy to manufacture and low in cost to simplify construction processes, to improve construction precision and to reduce construction cost. The multi-functional casing pipe part is characterized in that the casing pipe part is formed by splicing a plurality of cylinder units, and every cylinder unit is axially provided with three channels of a central anchor rod channel, a grouting channel and an exhaust channel, wherein the grouting channel and the exhaust channel are arranged on both sides of the anchor rod channel. The multi-functional casing pipe part is applicable to the fields such as water resource and hydropower engineering, municipal traffic engineering and construction foundation engineering.

[0003] At present, bolt construction methods and procedures are relatively cumbersome, and each procedure consumes a variety of equipment costs, time costs and labor costs

In the construction of soil bolts, for rock and soil with poor engineering geology, such as drilling holes in loose sandy soil and soft soil layers, it is easy to collapse. The collapse is caused by the limited self-stabilization ability of the rock and soil with poor engineering geology, especially During the time when the drilling is completed but the anchor rod is not put in and the grouting is not completed, the anchor rod cannot be inserted smoothly after the drill hole collapses. Generally, the collapsed hole is dealt with by backfilling first, followed by grouting and hardening treatment, and then forming the hole , time-consuming and labor-intensive, resulting in economic waste, the quality of the final hole cannot be guaranteed, and the mechanical properties of the soil in the collapsed hole are also reduced.

The construction accuracy cannot be accurately grasped during construction, the length of the free section of the anchor bolt and the anchor section cannot be accurately positioned according to the design value, and problems such as deviation and insufficient protective layer often occur after the anchor bolt is inserted
