[0034] like Figure 1-6 As shown, a prefabricated concrete pipe-cushion integrated device of the present invention comprises a plurality of standard blocks, two adjacent standard blocks are connected in a straight line, and each of the standard blocks comprises:

[0035] The base 100 is in the shape of an elongated strip, and a receiving groove 110 is provided on the base 100. The receiving groove 110 is in the shape of an elongated strip and penetrates along the length direction of the base 100.

[0036] A concrete pipe segment 200 is transversely disposed in the receiving groove 110, and the concrete pipe segment 200 and the base 100 are integrally formed;

[0037] Wherein, the base 100 is provided with a hoisting reserved hole 300 to facilitate hoisting by a lifting device.

[0038] In the above embodiment, the base 100 and the concrete pipe section 200 are cast in one piece, which saves the concrete curing time of the separately made pipe stabilizing device and improves the construction efficiency;

[0039] The base 100 is in the shape of a long strip, and four corners thereof are provided with hoisting reserved holes 300, which facilitates hoisting by lifting equipment and improves safety;

[0040] According to a preferred embodiment of the present invention, between two adjacent standard blocks, the two ends of the two concrete pipe segments 200 that are close to each other are respectively recessed inwardly to form an annular groove and protrude outwardly to form an annular clamping ring, and the annular clamping ring is inserted into the annular groove to achieve the connection between the two adjacent standard blocks.

[0041] During actual installation, it is relatively convenient, and only the concrete pipe sections 200 in two adjacent standard blocks need to be snap-fitted and installed.

[0042] According to a preferred embodiment of the present invention, between two adjacent standard blocks, the gap connecting the two bases 100 and the gap connecting the two concrete pipe sections 200 belong to the same plane, and the connecting ends of the two adjacent bases 100 are recessed downward to form a grouting reserved hole 400, and both ends of the grouting reserved hole 400 extend to the upper surface of the base 100.

[0043] After two adjacent standard sections are clamped together, concrete is poured into the interior through the grouting reserved holes 400 to enhance the sealing of the joints and ensure the construction quality.

[0044] According to a preferred embodiment of the present invention, a sewage pipe is passed through and placed inside the concrete pipe segment 200, and a plurality of groups of running wheels 700 are arranged on the inner wall of the concrete pipe segment 200 along its length direction, and each group of running wheels 700 includes two running wheels 700, both of which are close to the inner bottom of the concrete pipe segment 200, and the two are symmetrically arranged along the axis of the concrete pipe segment 200.

[0045] Considering that it is inconvenient to drag the sewage pipe in the concrete pipe section 200 and it may cause damage to the sewage pipe, targeted improvements are made in the above implementation scheme, and walking wheels 700 are provided in the concrete pipe section 200. In this way, when dragging the sewage pipe, the rolling of the walking wheels 700 can be utilized, saving time and effort.

[0046] According to a preferred embodiment of the present invention, the positions of the concrete pipe sections 200 corresponding to the walking wheels 700 are all sunken to form grooves 210, which are filled with sponges 500. The sponges 500 are soaked in lubricating oil before use. A cover plate 600 is provided on the surface of the sponge 500, and one end of the spring 800 is connected to one side of the cover plate 600, and the other end of the spring 800 is connected to the bottom of the groove 210, and a plurality of lubricating oil nozzles 610 are provided on the surface of the cover plate 600. The walking wheels 700 are installed on the cover plate 600, and the lubricating oil nozzles 610 are distributed in a ring along the walking wheels 700.

[0047] In this way, when the sewage pipe is being dragged, the travel wheel 700 will further press down the cover plate 600 under the pressure of the sewage pipe, and then the spring 800 will be compressed. During this process, the sponge 500 will be squeezed, and the lubricating oil therein will be squeezed out and sprayed to the steel part of the travel wheel 700 through the lubricating oil nozzle 610 to lubricate it and avoid rusting due to long-term use, which will cause poor walking.

[0048] According to a preferred embodiment of the present invention, when the spring 800 is in a naturally extended state, the highest end of the walking wheel 700 installed on the cover plate 600 is slightly higher than the inner wall of the concrete pipe section 200 .

[0049] According to a preferred embodiment of the present invention, the lubricating oil nozzles 610 are through holes that penetrate along the thickness direction of the concrete pipe section 200, and are all inclined. All of the lubricating oil nozzles 610 are inclined inward, and the nozzles are directed toward the steel part of the walking wheel 700 installed on the cover plate 600. At this angle, the steel part of the walking wheel 700 can be precisely sprayed and lubricated.

[0050] According to a preferred embodiment of the present invention, a connecting piece 900 is further provided between two adjacent concrete pipe sections 200, and its length can be adjusted by external pulling. The connecting piece 900 includes:

[0051] A sleeve 910 having a through hole extending through the sleeve along its height direction;

[0052] a baffle 920, which is fixedly built into the sleeve 910, and the baffle 920 is perpendicular to the height direction of the sleeve 910, dividing the internal space of the sleeve 910 into two sections;

[0053] Two connecting rods 930, one end of which extends into the sleeve 910 from both ends of the sleeve 910, and then passes through the baffles 920 respectively, and the connecting rods 930 can move relative to the baffles 920 without falling off, and the other end of the connecting rods 930 is pre-buried in the concrete pipe section 200.

[0054] In the above implementation scheme, as the concrete expands and contracts internally and deforms, when a small internal deformation is about to occur, the tie rod between the two will be dislocated under the action of stress tension to offset the stress caused by the thermal expansion and contraction of the concrete and avoid concrete cracking caused by deformation stress.

[0055] According to a preferred embodiment of the present invention, during the pouring process of the concrete pipe segment 200, a plurality of steel mesh sheets are annularly buried in the concrete, and two adjacent steel mesh sheets partially overlap.

[0056] A steel mesh is embedded in the concrete, and the tensile force of the steel mesh is used to improve the concrete's resistance to cracking. Considering that a single steel mesh has limited tensile force, in order to further improve the tensile force, multiple steel meshes are provided, and two adjacent steel meshes partially overlap, so that the concrete's resistance to cracking can be improved without dead angles.

[0057] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
