Description

Technical Field

[0001] The utility model relates to a municipal pipeline basic module. Background Art

[0002] At present, in the construction of municipal pipelines, concrete pipes and inspection wells are generally produced by prefabricated component factories and transported to the site for assembly and use. Concrete pipes generally adopt socket-type concrete pipes. The structure can be seen in Chinese patent CN200410056874.5. It is composed of multiple pipe units plugged into an integral pipe. Each pipe unit includes a cylindrical pipe body and a trumpet-shaped pipe joint located at one end of the pipe body in the length direction.

[0003] However, the foundations and pipe seats of existing municipal concrete pipes still use the on-site cast-concrete construction method. This construction method requires first pouring the pipe foundation, then hanging the concrete pipe when the foundation has a certain bearing capacity, and then supporting the formwork to cast the concrete pipe seat after the concrete pipe is assembled. Then, the pipe joints are processed and the pipes are backfilled. The construction period is long, a large amount of manpower and formwork are used on site, the cost is high, and the efficiency is low. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a municipal pipeline foundation module, which solves the problems of long construction period, high consumption and high cost of on-site pouring of municipal pipeline foundation and pipe seat by modular prefabrication.

[0005] In order to solve the above technical problems, the utility model provides a municipal pipeline foundation module, including a pipeline receiving portion, wherein the pipeline receiving portion includes a horizontally arranged rectangular block with a length direction running in a front-to-back direction, a long strip groove with a length direction running in a front-to-back direction, a semicircular cross-sectional shape and an upwardly arranged opening provided on the upper side of the rectangular block, both sides of the long strip groove in the length direction pass through to the front and rear ends of the rectangular block, a horizontal plate extending horizontally forward is provided on the lower front side of the rectangular block, the lower side of the horizontal plate is flush with the lower side of the rectangular block, and the upper side of the horizontal plate is lower than the bottom of the long strip groove Height, both sides of the horizontal plate in the width direction are flush with the corresponding sides of the rectangular block in the width direction, and a vertical plate extending forward is provided on the front side of the rectangular block near both ends in the width direction. The front sides of the two vertical plates are flush with the front sides of the horizontal plates, and the side of the two vertical plates that are close to each other in the left and right directions is defined as the inner side and the side that is separated from each other is defined as the outer side. The outer side surfaces of the two vertical plates are flush with the outer side surfaces of the corresponding side of the rectangular block, and the spacing between the inner sides of the two vertical plates in the left and right directions is greater than the width of the upper opening of the long strip groove. The two vertical plates and the horizontal plate together form a flat-bottomed U-shaped groove with an open upper side for accommodating the pipe interface.

[0006] Preferably, at least two hanging rings are arranged at intervals in front and back on the upper side of the rectangular block at the left and right sides corresponding to the long strip groove.

[0007] For the purpose of simple explanation, the municipal pipeline basic module described in the present invention is referred to as this module below.

[0008] The construction method of this module includes the following steps:

[0009] (1) The prefabricated component factory prefabricates the municipal pipeline foundation module according to the size of the municipal concrete pipeline, and the municipal pipeline foundation module uses C30 concrete;

[0010] (2) Lay out the target area for excavation of pipelines according to the pipeline construction drawings and spread white lime. Excavate the pipeline trench with the excavator according to the white lime line. Excavate to the pipe bottom elevation and then do manual excavation for the remaining 20-30cm. After the excavation is completed, the bottom elevation, width and foundation bearing capacity of the trench are inspected and accepted;

[0011] (3) For areas with insufficient foundation bearing capacity, first replace the ground with gravel according to the specifications, and then lay a 5cm thick medium-coarse sand cushion to ensure the flatness of the module foundation;

[0012] (4) Transport the municipal pipeline foundation modules that have passed the acceptance inspection of the prefabricated component factory to the construction site. Use a flatbed truck for transportation. When loading the prefabricated modules, secure them firmly with wooden boards. Use a road with good road conditions to reduce bumps.

[0013] (5) The municipal pipeline foundation modules transported to the site shall be jointly inspected and accepted by the construction unit, supervision unit and testing unit to check whether there are any damages or corners, and whether the concrete strength meets the requirements. After passing the inspection, the municipal pipeline foundation modules shall be hoisted by a crane. The municipal pipeline foundation modules shall be fixed along the front and back ends in the pipeline groove. When installing the municipal pipeline foundation modules, the project technicians shall lay out the lines in advance to ensure the accurate installation position of the modules, and supervise the entire installation process and make timely corrections;

[0014] (6) Hanging and placing the pipe monomers of the municipal concrete pipe on the assembled municipal pipe foundation module. The pipe body of the pipe monomer is matched with the long strip groove on the rectangular block. The trumpet-shaped pipe joint of the pipe monomer is placed in the flat-bottomed U-shaped groove. The pipe monomer adopts a rubber ring socket-type concrete pipe. After the pipe monomer is hung and assembled, fine stone concrete is poured into the gap between the trumpet-shaped pipe joint of the pipe monomer and the flat-bottomed U-shaped groove, so that each pipe monomer is combined with the corresponding municipal pipe foundation module into a whole;

[0015] (7) Inspect and accept the completed municipal concrete pipes and municipal pipe foundation installation, check whether the slope, height and straightness of the municipal concrete pipes and municipal pipe foundation installation are qualified, and conduct a functional water-tightness test on the entire pipe after passing the test, and check whether there is water seepage at the joints.

[0016] Advantages of this module: This module adopts modular prefabrication. The module and pipe units can be transported to the site for direct assembly. The prefabrication method reduces the time for on-site formwork installation and concrete curing, eliminates the construction intervals between each process, speeds up construction, and greatly shortens the construction period. It is particularly suitable for tight construction periods and poor construction environments, such as construction during the rainy season, and can be completed quickly during the rainy season. From an environmental perspective, since this module and pipe units are produced by prefabricated component factories, the construction site does not generate environmental pollution caused by pouring a large amount of concrete and constructing formwork, which not only saves resources but also greatly reduces the burden on the environment, in line with the green and environmentally friendly construction advocated by the country. In terms of molding quality, all prefabricated components (this module and pipe units) are prefabricated in the factory. After the prefabricated assembled pipeline construction is completed, its linear shape and concrete strength can be guaranteed.

[0017] Moreover, the construction method and steps are simple and rigorous, the construction speed is fast, and the seamless connection between each process forms a flow operation, thereby improving work efficiency, saving labor costs during the construction process, speeding up the construction speed, and greatly shortening the construction period.
