Support member for repairing underground pipeline

Technical Field

The utility model relates to a pipeline maintenance apparatus field especially relates to an underground pipeline maintenance support piece.

Background

Underground pipelines are laid in a plurality of cities at present, and a semicircular supporting plate with a nut is disclosed in patent publication CN111779887A, and can well support soil above the pipelines, but the supporting plate rotates relative to the underground soil due to the fact that the outer wall of the semicircular supporting plate is a smooth circular arc, so that the supporting plate with the structure deflects easily on the supporting soil, and the difficulty of embedding the supporting plate into the soil is increased.

SUMMERY OF THE UTILITY MODEL

To the above problems, the utility model provides an underground pipeline maintenance support piece.

The utility model adopts the following technical scheme:

the utility model provides an underground pipe repair support piece, includes the plate body, the plate body is the semicircle arcuation, the internal face of plate body is the internal face of level and smooth form, be provided with a plurality of indents on the outer wall of plate body, the indent is the indent of U word form, and the degree of depth of indent is no longer than 1/3 of plate body thickness.

Among this kind of support piece, set up the indent on the outer wall of semicircle arc-shaped plate body, and the degree of depth of indent is no longer than 1/3 of plate body thickness, so it is less relatively to plate body intensity influence to set up the indent on the plate body, set up the indent on the outer wall of plate body, the existence of indent can be so that in the partial earth embedding indent, can increase the resistance that the plate body received when rotating for earth under the prerequisite that does not increase plate body embedding earth frictional force like this, make between plate body and the earth become difficult rotation relatively, so the support piece of this kind of structure can increase the resistance of earth under the prerequisite that does not increase earth resistance

Optionally, the two ends of the plate body are respectively provided with positioning columns and positioning holes, the number of the positioning holes is equal to that of the positioning columns, and the length of the positioning columns is smaller than the depth of the positioning holes.

The two ends of the plate body are respectively provided with the positioning hole and the positioning column, so that two adjacent plate bodies (contacting and not in the same circle) can be matched with each other through the positioning column and the positioning hole in a locking manner, and the two adjacent plate bodies (contacting and not in the same circle) can play a positioning role, so that the two adjacent supporting plate bodies are ensured to be stable.

Optionally, the positioning hole is a circular positioning hole, and the positioning column is a bullet-shaped positioning column.

The circular positioning hole and the bullet-shaped positioning column are adopted, and the matching is to ensure that the positioning column can be smoothly inserted into the positioning hole in the alignment process of the two plate bodies.

Optionally, the plate body is a steel plate body, and the positioning column is made of an aluminum alloy material.

The aluminum alloy positioning column and the steel plate body are adopted, so that the positioning column is prevented from being corroded in the positioning hole of the plate body. Because the plate body needs to be laid below the road, in order to avoid ensuring that the plate body has good supporting performance on the road surface, the plate body is made of steel, and the plate body is ensured to have good supporting performance on the road surface.

Optionally, an acrylic resin film is provided at the end edges of the plate body.

The acrylic resin film is adopted to play a role of a sealing gasket, so that good waterproof performance between two adjacent plate bodies (including those positioned in the same circle and those not positioned in the same circle) is ensured, and meanwhile, as the acrylic resin film has good flexibility, when the positioning column is matched with the positioning hole, the positioning column can smoothly puncture the acrylic resin film.

Optionally, a sink groove is formed in the inner wall surface of the plate body.

Set up heavy groove on the internal face of body, can fill in the reinforcing bar in heavy inslot for the both ends of reinforcing bar respectively with two adjacent plate body contacts, then with reinforcing bar and plate body welded fastening together, can be with the joint strength of two adjacent plate bodies like this, make the pipe that the plate body encloses have stronger shock resistance, when the oversize vehicle of road surface top drives and arouses the road surface vibrations, the pipe that the plate body encloses is difficult for scattering more.

Optionally, the sinking groove is a square sinking groove.

The square sinking groove is convenient for placing channel steel in the sinking groove, and the channel steel is used for connecting the two plate bodies. Because the channel steel has stronger tensile and torsional properties relative to the reinforcing steel bars, the channel steel is adopted to connect the two plate bodies.

Optionally, the depth of the sinking groove is smaller than the depth of the concave recess.

The utility model has the advantages that: the resistance that receives when can increase the plate body and rotate for earth under the prerequisite that does not increase plate body embedding earth frictional force for become relative difficult the rotation between plate body and the earth.

Description of the drawings:

figure 1 is a schematic diagram of an underground pipe repair support,

fig. 2 is a schematic sectional view taken along the line a-a in fig. 1.

The various reference numbers in the figures are: 1. a plate body; 101. recessing; 102. positioning holes; 103. sinking a groove; 2. and a positioning column.

The specific implementation mode is as follows:

the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the support member for maintaining underground pipelines comprises a plate body 1, wherein the plate body 1 is in a semicircular arc shape, the inner wall surface of the plate body 1 is a smooth inner wall surface, a plurality of concave recesses 101 are arranged on the outer wall surface of the plate body 1, the concave recesses 101 are U-shaped concave recesses 101, and the depth of the concave recesses 101 is not more than 1/3 of the thickness of the plate body 1.

Among this kind of support piece, set up indent 101 on the outer wall of semicircle arc-shaped plate body 1, and the degree of depth of indent 101 is no longer than 1/3 of plate body 1 thickness, so it is relatively less to plate body 1 intensity influence to set up indent 101 on plate body 1, set up indent 101 on plate body 1's the outer wall, the existence of indent 101 can make in partial earth embedding indent 101, can increase the resistance that plate body 1 received when rotating for earth under the prerequisite that does not increase plate body 1 embedding earth frictional force like this, make between plate body 1 and the earth become difficult the rotation relatively, so the support piece of this kind of structure can increase the resistance of earth under the prerequisite that does not increase earth resistance

As shown in fig. 1 and fig. 2, two ends of the plate body 1 are respectively provided with positioning columns 2 and positioning holes 102, the number of the positioning holes 102 is equal to the number of the positioning columns 2, and the length of the positioning columns 2 is smaller than the depth of the positioning holes 102.

The two ends of the plate body 1 are respectively provided with the positioning hole 102 and the positioning column 2, so that two adjacent plate bodies 1 (which are in contact and not in the same circle) can be mutually locked and matched together through the positioning column 2 and the positioning hole 102, and thus the two adjacent plate bodies 1 (which are in contact and not in the same circle) can play a positioning role, so that the two adjacent supporting plate bodies 1 are ensured to be kept stable.
