Problems solved by technology

In the field of prefabricated power pipe galleries, most of the prefabricated concrete rectangular pipe galleries are currently used. Although the problem of using prefabricated components for assembly and construction has been solved, the pipe gallery of this structural form has the problems of excessive self-weight and poor interface sealing. The cost of hoisting and transportation is high, and there are defects in the sealing performance of the interface that affect the use. In addition, because the impermeability of concrete is limited by the inhomogeneity of the material itself, there may be leakage of the gallery body, and there are also quality risks
There is also an application in the project that uses prestressed concrete circular pipes as a power pipe gallery, but the prestressed components are more sensitive in terms of corrosion resistance, and the application of prestressing technology in the power pipe gallery has the risk of electric field corrosion and some problems

specific Embodiment

[0033]Specific examples: trench excavation: excavate the trenches of the pipe gallery to be laid according to the relevant national specifications, the key is to ensure the accuracy of the axis and orientation of the trench, as well as the safety of the slope; base treatment: for the soil pipe foundation, Slight compaction and leveling; for concrete pipe foundations, the top surface elevation and flatness should be ensured during pouring; preparations before installation of the pipe gallery: A. Clean the bearing and socket working surfaces of the joints of the pipe gallery to be installed to ensure There are no sundries and sharp burrs on it; B. Apply lubricating oil evenly on the working surface of the bearing and socket; C. Put the sealing rubber ring (2 pieces in total) into the groove of the socket, and hook it up with a wire and clockwise and slide counterclockwise around the circumference 2 times each to ensure that all parts of the sealing rubber ring are stretched evenl...

Abstract

The invention discloses a precast steel cylinder concrete circular power pipe corridor with a pipe base. The precast steel cylinder concrete circular power pipe corridor comprises a reinforced concrete pipe body, the pipe base, a structural steel bar, a pipe base structural steel bar, a seepage-proof steel cylinder, a socket, a spigot, buried slots, a buried load bearing suspension rail, a buriedlifting port and grounding flat steel. The seepage-proof steel cylinder is welded integrally with the socket and the spigot. The seepage-proof steel cylinder is loaded into a special mold, and the reinforced concrete pipe body is poured to form an integral reinforced concrete structure. The pipe base and the reinforced concrete pipe body are poured at the same time and integrally formed. The buried slots, the buried load bearing suspension rail, the buried lifting port, a sealing inspection hole and grounding flat steel are all embedded in the design position before concrete pouring and then poured in the pipe body. The precast steel cylinder concrete circular power pipe corridor has the advantages that the pipe wall is thin, the installation is convenient and quick, the seepage-proof performance is good, the buried slots convenient for installing various cable supports are arranged on the inner wall of the pipe corridor, the installation of equipment and pipelines in the corridor is facilitated, the extraction device of metal grounding facilities is arranged and the problems of electric field corrosion and the like are solved.

Description

technical field [0001] The invention relates to the field of urban underground road engineering and the technical field of municipal facilities, in particular to a prefabricated steel cylinder concrete circular power pipe gallery with pipe sockets. Background technique [0002] With the continuous improvement of the level of social and economic development and the country's promotion of environmental protection, energy saving, and green economy, more and more prefabricated components are used in the field of basic construction, especially in the field of concrete products. The application of prefabricated concrete components is increasing. widely. In the field of prefabricated power pipe galleries, most of the prefabricated concrete rectangular pipe galleries are currently used. Although the problem of using prefabricated components for assembly and construction has been solved, the pipe gallery of this structural form has the problems of excessive self-weight and poor inter...
