Abstract

The utility model relates to a novel blasting embedded pipe which is structurally composed of a pipe body and a head portion. The tail end of the head portion is inserted to the pipe body, the taper of the front part of the head portion is 60 degrees, the pipe body is formed by rolling textile spool paper, and the head portion is formed in a die-casting mode through plastics. The novel blasting embedded pipe solves the problems that in the prior art, a PVC pipe is high in cost, difficult to block and low in efficiency, a paper tube is usually pinched to be flat by fingers, labor intensity is large, and when the PVC pipe needs to be inserted into concrete, the PVC pipe can not be inserted into the concrete due to blocking of transverse reinforcement in the concrete and needs to be pulled out and then inserted into other positions, and labor efficiency is low. The novel blasting embedded pipe is low in cost and convenient to use, and can be easily inserted into concrete, the position of the embedded pipe can be automatically adjusted when the embedded pipe encounters reinforcement, labor intensity of workers is lowered, and work efficiency is improved.

Description

A kind of Novel explosion built-in pipe

Technical field

The utility model relates to blasting technique field, particularly a kind of Novel explosion built-in pipe.

Background technology

For the explosion of armored concrete that needs demolition blasting, conventionally adopt hole firing method, the blasthole diameter of this blasting procedure is no more than 50mm, and the degree of depth is no more than 5m.The formation in big gun hole, a kind of method is to use hand-held or pusher leg drill and drill jumbo boring, and this method mechanization degree is low, and labor strength is large, and labor productivity is low.Another kind method is in cast concrete, the built-in pipe that is used to form big gun hole of burying underground, and this method labor strength is low, and labor productivity is high, is generally adopted.

Before the present utility model, there is not the built-in pipe of the explosion of being specifically designed to now, in construction, conventionally select pvc pipe or the paper tube of same outer diameter.Burying built-in pipe underground, is in 1～2 hour, built-in pipe to be inserted in unhardened armored concrete after pouring concrete, and this just need to block one end of built-in pipe in advance, prevents that concrete from entering in pipe.Pvc pipe adopts heating means conventionally, after pvc pipe deliquescing, flattens; Paper tube is firmly pinched flat with finger conventionally.But these two kinds of built-in pipes have obvious shortcoming: 1, pvc pipe cost is high, when shutoff pvc pipe, bothers, and efficiency is low.2, paper tube is pinched flatly with finger conventionally, and labour intensity is large.3, no matter be pvc pipe or paper tube, inserting when concrete, easily run into the transverse steel of inside concrete and insert not enter, need to again pull out and change position, efficiency is declined.

Summary of the invention

The purpose of this utility model is just to overcome above-mentioned defect, develops a kind of Novel explosion built-in pipe.

The technical solution of the utility model is:

A kind of Novel explosion built-in pipe, its technical characteristics is to be made up of pipe shaft, head, and head tail end inserts in pipe shaft.

The anterior tapering of described head is 60 °.

Described pipe shaft adopts cop tube paper to roll and forms.

Described head plastics die cast.

Advantage of the present utility model and effect are to provide a kind of cheap, easy to use explosion built-in pipe, built-in pipe is inserted in concrete process and easily insert, and automatic adjusting position in the time running into reinforcing bar, reduces labor strength, raises labour efficiency.

Accompanying drawing explanation

Fig. 1---the utility model pipe shaft generalized section.

Fig. 2---the utility model head generalized section.

The generalized section of Fig. 3---the utility model pipe shaft and head combination.

In figure, each label represents that corresponding component names is as follows:

1-pipe shaft, 2-head.

The specific embodiment

As shown in Figure 1:

Built-in pipe is divided into pipe shaft 1 and head 2 two parts, and the tail end of head 2 inserts in pipe shaft 1, and with glue, the two is bonding.Described pipe shaft 1 adopts cop tube paper to roll and forms; Said head 2, generally uses plastics die cast.

The anterior tapering of head 2 is 60 °, hollow, and wall thickness is that 2mm is good, and pipe shaft 1 wall thickness is that 2mm is good, and length and external diameter are according to needing making, and the tail end external diameter of head 2 and the internal diameter of pipe shaft 1 are take interference fits as good.

The explanation of the utility model application process:

Head 2 is inserted in pipe shaft 1 one end, bonding with glue; In the time that built-in pipe is used in the pre-buried explosion of need, in concreting after 1～2 hour, manually explosion built-in pipe is inserted in concrete, head 2 is introduced into, this is just very easy to insert, in the time of the reinforcing bar running in concrete, head 2 also can automatic adjusting position, and whole pipe shaft 1 is also entered in concrete smoothly.

Explosion built-in pipe of the present utility model, application result shows, the explosion built-in pipe that the present invention makes, at beforehand burying phase, can be raised the efficiency 3～4 times, has obtained good effect.
