Rocket burrowing anchor

Abstract

The invention discloses a rocket burrowing anchor. The rocket burrowing anchor comprises a bullet, a secondary triggering expansion anchor mechanism part, a rocket engine part and an anti-twist gyrostat, wherein the tail of the bullet is fixedly connected to the head of the secondary triggering expansion anchor mechanism part, the tail of the secondary triggering expansion anchor mechanism part isfixedly connected to the head of the rocket engine part, the tail of the rocket engine part is fixedly connected to the head of the anti-twist gyrostat, and the tail of the anti-twist gyrostat is connected to an underground anchor cable; the outer surfaces of housings of the bullet, the expansion anchor and the rocket engine are provided with double-spiral cutting wings. In the rocket burrowing anchor, the technical advantage of strong rocket thrust is utilized, an anchor body can burrow deeply, form a rooting strongpoint quickly in the soil body, and then be combined with the anchor cable atthe tail connected to a fixing pile, a cast stuff is hung on the anchor cable to be subjected to slide cast, and thus the cast stuff can take root at the entrance quickly, and not be washed away by astream.

Description

technical field [0001] The invention belongs to the technical fields of river and lake blocking technology, large river closure construction and the like, and in particular relates to a rocket-drilled ground anchor. Background technique [0002] my country is a country prone to floods, and dam breaches caused by floods during flood seasons seriously threaten local agriculture, transportation, ecological environment, and the safety of residents' lives and property. After a river embankment breach occurs, the flow rate at the breach gate is usually relatively high. Due to time constraints, the thrown objects are generally obtained locally. These thrown objects are small in size and light in weight, and are easily destroyed after being thrown into the breach. When the water flows away, it is difficult to quickly and stably take root at the breach to complete the task of breach blocking and rehabilitation. Similarly, during the closure construction of large-scale water conserva...

AI Technical Summary

Problems solved by technology

The anchor of this utility model is a fixed type, and the anchor of this structure will greatly disturb the soil around the anchor body after entering the soil, increasing the diameter of the cavity around the anchor body, thereby reducing the anchoring force of the anchor body; In this utility model, the anchor cable is hung on the lifting lug arranged on the anchor body, and the problem that the anchor cable is twisted and knotted due to the rotation of the missile body during the operation of the rocket is not considered.
