Description

[Detailed description of the invention] This invention relates to a connection device between a three-passage hose and a single-passage pipe for injecting cement milk or mortar into the ground.

Generally, inside a borehole drilled at a predetermined angle to the retaining wall,
A plurality of steel wires with their tips exposed and the rest covered with pipes are inserted, and cement milk or mortar (
In a device for fixing a group of steel wires in an excavated hole by injecting mortar (hereinafter referred to as mortar), a hose that communicates with a mortar supply source on the ground is disposed within the group of steel wires, and the inside of the hose is connected to three parts by a partition wall. It is divided into main passages, two passages open in the middle of the steel wire, and one passage opens at the tip of the steel wire, allowing mortar to be spewed out.

This invention relates to a device that connects one passage of the hose to a single passage pipe such as a vinyl pipe, and shortens the length of the three passage hose and makes the hole to be drilled underground narrower. The purpose is to reduce costs.

The invention will be explained by way of example in the accompanying drawings, in which the hose 1 is divided by partition walls 2.2', 2'' and forms three passages 3.3', 3''.

An inner tube 4 is glued to the tip of the hose 1.

The inner cylinder 4 is formed with an inclined opening 5 whose rear end opens into one of the passages 3 and whose tip opens approximately at the center.

A screw 6 is provided on the outer periphery of the hose 1 and the inner tube 4, the female screw of the outer tube 7 is fitted onto the male screw 6, and the base 10 of the nozzle 9 is screwed into the center hole of the end plate 8 of the outer tube 7. .

A pipe 11 is connected to the tip of the nozzle 9.

This pipe 10 has a length of about 10 m.

In the drawings, 12 indicates a gasket, and 13 indicates a hexagonal nut.

When mortar is fed into the passage 3 using the above-ground part of the hose 1, the mortar passes through the inclined hole 5 of the inner cylinder 4, passes through the nozzle 9, flows through the pipe, is discharged into the ground from the tip of the pipe, and is discharged into the ground from the tip of the pipe. This is to fix the

The present invention has the above-mentioned configuration, and one passage of the hose can be connected to the pipe by using the inner tube 4, the outer tube 7, and the nozzle 9, thus shortening the length of the three-passage hose 1. This can save costs.

Furthermore, since the pipe 11 is thinner than the three-channel hose 1, the hole to be drilled into the ground can also be narrower, which has the effect of reducing construction costs accordingly.
