Description

Auxiliary medicine roll pusher and method

Technical Field

The invention relates to the field of long anchor cable construction, in particular to an auxiliary explosive cartridge pusher and a method.

Background

At present in long anchor rope (being greater than 6m) work progress, can use a plurality of resin anchoring agent (cartridge) to combine together, stir to drilling terminal with the steel strand wires propelling movement, but at the in-process of steel strand wires propelling movement resin cartridge, receive the drilling depth, propelling movement process time is long and drilling hole contact surface is not smooth and causes the cartridge impaired, unable complete propelling movement to final hole position, cause the not enough resin clay that the anchoring agent dose is not enough or the not enough resin cartridge curing agent is not solidified, the steel strand wires is fixed insecure, the pretightning force does not reach the designing requirement, the anchor rope construction fails.

In the construction, the anchor cable is not successful in one-time construction, the anchor cable needs to be pulled out, secondary drilling and hole sweeping are carried out, the anchor cable is injected secondarily, and great waste of materials and manpower is caused. Particularly, the anchor cable is injected into rock with unstable lithology and more layers or loose rock, so that the success rate of injecting the anchor cable is low, the construction efficiency is greatly limited, the great economic loss is caused, and the construction period is delayed.

When the anchor cable is constructed, in the process of pushing a plurality of resin anchoring agents (explosive cartridges) to a final hole by using the steel strand, the damage of the explosive cartridges is caused by the following reasons: 1. the explosive cartridge forms certain straightness, and is bent when being pushed, so that the construction quality is influenced; 2. the diameter of the explosive cartridge is much smaller than that of the drill hole, and the explosive cartridge is extruded from the head to the tail in a crossed manner and cannot form a straight line, so that the explosive cartridge is extruded by the steel stranded wire in the pushing process.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments and drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the scope of protection of this patent.

The invention provides a cartridge auxiliary pusher, as shown in fig. 1 and 2, comprising: the main rod 1 is provided with a plurality of guide rods 2, and the guide rods 2 are connected with the guide rods 2 through connecting sleeves 3; the medicated roll 4 is fixed on the guide rod 2; one end of the main rod 1 is provided with a steel strand 5 used for pushing the guide rod 2 and the explosive cartridge 4 to a preset position.

The guide rod 2 is provided with cones 7 at both ends. That is, the cones 7 of the guide rods 2 provided at both ends of the main rod 1 may serve the purpose of facilitating the pushing.

The medicated roll 4 is resin anchoring agent.

The connecting sleeve 3 is made of polyethylene adhesive tape; the adjacent guide rods 2 are connected through connecting sleeves 3, and the cartridges 4 on the adjacent guide rods 2 are connected through the connecting sleeves 3. Therefore, the connecting sleeve 3 forms a whole between the explosive sticks 4 and between the guide rods 2, and the operation is convenient.

The guide rod 2 is a flexible rod; the guide rod 2 is made of rubber. The guide rod 2 has toughness, and can play a role in buffering and avoiding breaking when encountering obstacles.

The length of the main rod 1 is set according to the required total length of the explosive stick 4. The guide rod and the explosive cartridge 4 can be fixed in a plurality of matching modes.

For example, the inside of the guide rod 2 is a hollow structure, and the cartridge 4 is placed inside the hollow structure of the guide rod 2. This may serve to secure the cartridge 4.

In another way, the medicated roll 4 is bound on the guide rod 2 by a binding belt, and can be fixed by other ways.

Compared with the prior art, as shown in fig. 3, in the pushing process of the long anchor cable pesticide application coil, due to the fact that the drill hole is deep, the inner wall of the drill hole is not smooth or the pesticide application coil is not consistent with the diameter of the drill hole, the pesticide application is affected by mutual staggering and extrusion of the pesticide application coils, and the application is also affected by the influence on construction quality.

As shown in fig. 4, the explosive cartridge is damaged in the pushing process by using the steel strand, and the explosive cartridge cannot be sent to a designated position, so that the injection of the anchor cable fails, the use is affected, and the construction quality is also affected.

As shown in figure 5, after the pusher and the cartridge are fixed together, the steel stranded wire is used for pushing the cartridge, so that the cartridge can be completely pushed to a specified position, and the construction quality is improved.

The auxiliary explosive roll pusher can improve the construction success rate of the anchor cable and improve the construction efficiency. In the test process of using 3 explosive cartridges in the construction of steel strand with the diameter of 21.6mm and the length of 8m, the construction efficiency can be integrally improved to 25 percent, and particularly, the efficiency of workers with low proficiency is improved most obviously.

The invention also provides a method for pushing the cartridges, which comprises the following steps:

setting the length of a main rod according to the length of a cartridge required by anchor cable construction, and acquiring the diameter of a drilled hole;

the number of the guide rods is set according to the length of the main rod, and the diameter of each guide rod is set according to the diameter of the drilled hole;

fixing the medicated roll with the guide rod;

leading the guide rod for fixing the explosive roll to be in tail connection through a connecting sleeve;

with steel strand wires one end and the mutual top of the one end of connecting the mobile jib that forms and hold, in propelling movement to hole, under the drive of mobile jib, construct in propelling movement to hole with the cartridge.
