Embodiment Construction

[0008] as attached figure 1 As shown, a device for reducing the volume of the hole and the volume occupied by the chemical slurry, including a rubber plug 3 and a slurry inlet pipe 9, a flower tube 4 at the bottom of the rubber plug 3, and a plurality of outer casings 5 ​​are arranged under the flower tube 4, The inside of the jacket 5 is connected by a grouting pipe 7 , and a grouting pipe 2 is arranged on the top of the rubber plug 3 , the hose 1 is connected with the grouting pipe 2 , and the hose 1 is connected with a liquid container 8 . The overcoat 5 of the present invention is a cylindrical structure made of wooden materials, and each section of the overcoat 5 is fixed by a pipe collar 6 .

[0009] Working process of the present invention is as follows:

[0010] When working, the chemical slurry enters through the slurry inlet pipe 9, and is injected into the hole section through the slurry injection tube 7. Due to the existence of the wooden jacket 5, the volume occu...

Abstract

The invention discloses a device for reducing in-hole volume and in-pipe volume occupied by chemical grout. The device comprises a rubber stopper and a grout inlet pipe; the lower part of the rubber stopper is provided with a floral pipe; a plurality of jackets are arranged below the floral pipe; the insides of the jackets are connected through a grout injection pipe; the upper part of the rubber stopper is provided with a grout return pipe; a hose is connected with the grout return pipe; the jackets have cylindrical structures, and each section of jacket is fixed by a pipe hoop; the jackets are made of wooden materials; the hose is connected with a grout container. The device is processed conveniently and mounted flexibly, can be matched with the grouting rubber stopper on site, can reduce the in-hole grout occupied volume and the grout return volume in a grouting hole section, and is economical and environment-friendly.

Description

technical field [0001] The invention relates to an engineering construction device, in particular to a device for reducing the internal volume of holes and tubes occupied by chemical grout in chemical grouting engineering. Background technique [0002] At present, in the irrigation construction of the foundation treatment project, the lower hole section of the rubber plug occupies a large amount of grouting slurry; the return slurry flows out from the gap between the inner and outer pipes through the slurry outlet pipe, which also takes up a lot of grouting slurry. For chemical grouting, not only is the grout wasted, it is not economical, but it is also not environmentally friendly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for reducing the volume of the hole and pipe occupied by the chemical grout. The device is easy to process and flexible to install. It can be used together with the grouting rub...
