Description

Cleaning protective cover for grouting pipeline

Technical Field

The utility model belongs to the technical field of the pipeline is maintained, especially, relate to a slip casting pipeline's washing protection casing.

Background

The grouting pipe is a necessary pipeline in underground construction, and is used for injecting grout into an area to be excavated of a mine so as to reinforce the area to be excavated and form a reinforcing strip in the area to be excavated, so that the integrity of a rock mass is improved, and the safety of a subsequent excavation process is improved.

The grouting pipe needs to be cleaned after the primary grouting is finished, so that sundries in the grout can not block the grouting pipe. The common cleaning mode is to wash the grouting pipe with high-pressure water, but materials, impurities and the like at the water outlet of the grouting pipe are discharged along with the high-pressure water, and the materials, the impurities and the like are likely to be sprayed out along with the high-pressure water to hurt people due to the very high pressure of the high-pressure water.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a slip casting pipeline's washing protection casing to when preventing to wash the slip casting pipe, material, debris in it are along with the water under high pressure blowout.

The utility model adopts the following technical scheme: a cleaning protective cover of a grouting pipe comprises a plurality of isolating strips extending along the outlet direction of a grouting pipe, wherein one ends of the isolating strips are annularly arranged and are arranged on a first flange plate at the outlet of the grouting pipe at intervals, the second ends of the isolating strips are mutually connected at the same point, and an isolating cavity is formed inside each isolating strip to prevent residual materials and impurities in the grouting pipe from being sprayed out along with high-pressure water for cleaning the grouting pipe;

gaps are formed between every two adjacent isolating strips and used for discharging high-pressure water for cleaning the grouting pipes;

the isolating strips are strip-shaped plate bodies, one end of each plate body is bent towards the outer side to form a first bent part, and the other end of each plate body is bent towards the inner side to form a second bent part; the through holes are formed in the first bending part and the second bending part.

Furthermore, the first ends of the plurality of isolating strips are connected with the first flange plate through the second flange plate.

Furthermore, the first bending part, the second bending part and the vertical plate body are arranged on the plate body.

Further, the length of the second bending part is larger than the radius of the grouting pipe.

The utility model has the advantages that: the utility model discloses a plurality of parting bead seals the slip casting pipe export, forms to keep apart and holds the chamber, can prevent that remaining material of slip casting pipe and debris from following the blowout of high pressure water, stays material and debris in keeping apart and holding the chamber to the high pressure water discharge that will wash the slip casting pipe through the clearance between the adjacent parting bead can prevent that material and debris in the slip casting pipe from spouting when washing and hindering the people.

Drawings

Fig. 1 is a schematic structural view of a cleaning protective cover of a grouting pipeline according to an embodiment of the present invention.

Wherein: 1. a spacer bar; 2. a second flange plate; 11. a first bent portion; 12. a second bending part.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The embodiment of the utility model discloses a washing protection casing of slip casting pipeline, as shown in figure 1, include a plurality of parting bead 1 that extends to set up along slip casting pipe outlet direction, the one end of a plurality of parting bead 1 is arranged annularly, and the interval sets up on the first ring flange of slip casting pipe outlet, the other end of a plurality of parting bead 1 interconnects on the same point, form inside a plurality of parting bead 1 and keep apart the appearance chamber to prevent interior residual material of slip casting pipe and debris from being sprayed along with the high pressure water that is used for wasing the slip casting pipe; gaps are formed between every two adjacent isolating strips 1 and used for discharging high-pressure water for cleaning the grouting pipes.

The utility model discloses a plurality of parting bead seals the slip casting pipe export, forms to keep apart and holds the chamber, can prevent that remaining material of slip casting pipe and debris from following the blowout of high pressure water, stays material and debris in keeping apart and holding the chamber to the high pressure water discharge that will wash the slip casting pipe through the clearance between the adjacent parting bead can prevent that material and debris in the slip casting pipe from spouting when washing and hindering the people.

Specifically, the size of the gap is specifically designed according to the size of the residual materials and impurities in the grouting pipe, so that the gap is prevented from being too small, high-pressure water is not discharged timely, and small materials or impurities are prevented from being sprayed out of the gap when the gap is too large.

Specifically, one end of each isolating bar 1 is connected with the first flange plate through the second flange plate 2. Through second ring flange 2, can be with a plurality of division bar 1 equal integrated an organic whole, convenient dismantlement, connection, accomodate etc..

As a concrete implementation form, the isolating strips 1 are strip-shaped plate bodies, the plate bodies have certain width, the isolating cavities can be formed by using less quantity, and the plate bodies are more convenient to connect and operate.

The plate body has two ends, one end is bent towards the first side surface (namely the outer side) to form a first bent part 11, the first bent part 11 is used for being connected with a second flange 12, the other end is bent towards the second side surface (namely the inner side) to form a second bent part 12, and the length of the second bent part 12 is larger than the radius of the grouting pipe. The second bending parts 12 are bent towards the same side of the plate body and are intersected, and finally are intersected on a grouting pipe axial line, and the grouting pipe axial line is connected through bolts to complete fixation.

In this embodiment, in order to facilitate the connection, the through holes are formed in the first bending portion 11 and the second bending portion 12, and the bolts are inserted into the through holes to fix the plate body. In addition, the disassembly and cleaning of the plate body can be realized.

In order to make the size of the separation cavity appropriate, the first bending part 11, the second bending part 12 and the vertical plate body form a cylindrical cavity with the same diameter as the grouting pipe.

The utility model discloses a chamber is kept apart in 1 formation of a plurality of parting strip, can prevent that material, debris blowout from hindering the people to, the simple manufacture of this protection casing, convenient to draw materials can be processed on the current material in building site and form, no longer need extra purchase, the maintenance of being convenient for.
