Description
Technical Field
The invention belongs to the technical field of underground pipe galleries, and particularly relates to a male and female groove lap joint type resin concrete cable pipe gallery.
Background
The cable pipe gallery is a structure and accessory facilities built under the city to accommodate two or more city engineering pipelines. The pipeline is laid in a centralized mode, occupied space of the road is greatly reduced, the pipeline is maintained, replaced in the inner space of the pipe gallery, congestion of urban traffic cannot be caused, and the pipeline is an important gripper for solving the problem of repeated excavation construction of the road. The comprehensive pipe gallery is built, underground space can be fully, reasonably and comprehensively developed, the contradiction between urban development and land resource shortage is relieved, the comprehensive utilization efficiency of land is improved, and the sustainable development of the economy and the society is realized.
At present, conventional cable piping lane all adopts traditional concrete cable piping lane, and this just leads to the easy local fracture of finished product and infiltration, and corrosion resistance is relatively poor, is corroded easily and not with the compatible environmental protection building material of ordinary mineral, and the construction process flow is loaded down with trivial details complicated, and monomer weight is heavier, the delivery difficulty, the installation difficulty, need use more manpower and financial resources. And a flexible socket joint sealing type is adopted, so that the process is complicated.
Aiming at the problems, a section is developed particularly, the construction can be convenient and fast, the weight of a single body is light according to the specification of the existing drawing, construction can be carried out by two persons, and mechanical assistance is not needed. But also can ensure that the breaking strength is more than 22N/mm, the strength of the finished product is 6 times of that of common concrete, the product has no penetration, is particularly suitable for quick drainage, has strong chemical resistance and uses the product of environment-friendly building materials compatible with common minerals to solve the problems caused by the traditional concrete cable pipe gallery.
Disclosure of Invention
The invention aims to provide a cable pipe gallery which is light in weight, high in strength, free of permeation, simple and convenient to lap and high in production speed.
In order to achieve the purpose, the invention adopts the technical scheme that:
a resin concrete cable pipe gallery comprises a plurality of U-shaped prefabricated members, wherein one end of each U-shaped prefabricated member is provided with a male head, the other end of each U-shaped prefabricated member is provided with a female groove matched with the male head, two adjacent U-shaped prefabricated members are connected with the female grooves in a lap joint mode through the male heads, a sealing glue applying groove is arranged in each female groove, and a rubber water stop strip is embedded in each sealing glue applying groove;
the outer wall rib of the U-shaped prefabricated member is provided with a plurality of reinforcing ribs.
Further, the U-shaped prefabricated member is made of resin concrete, and the manufacturing method of the U-shaped prefabricated member comprises the steps of mixing 20-25% of unsaturated resin and 65-70% of quartz sand in parts by weight, then adding 10% of curing agent and accelerator, then filling into a grinding tool, vibrating or pressing for 10 minutes, and then demoulding to obtain the resin concrete prefabricated member.
Further, the curing agent is a polyesteramine curing agent.
Further, the curing agent is a type 7 II accelerator.
Compared with the prior art, the invention has the following beneficial effects:
the U-shaped prefabricated members are connected in a lap joint mode through the male heads and the female grooves, and the joints of the male heads and the female grooves are fixed through the rubber-embedded water stop strips, so that the lap joint sealing performance between pipe galleries is enhanced, the strength is improved, the manual installation and lap joint are simple and convenient, and the construction period can be shortened.
The traditional common concrete used for the pipe gallery is changed into resin concrete, so that the strength of the U-shaped prefabricated member is improved, the weight of the U-shaped prefabricated member is lighter, and the transportation is convenient. In addition, the surface of the resin concrete member is smooth, the corrosion resistance is strong, and the resin concrete member is impermeable to water. The resin concrete is a polymer concrete which is made by taking special unsaturated resin as a cementing material, matching with a specially-adjusted curing agent and taking high-strength quartz sand as an aggregate, has the technical performance greatly superior to that of common concrete, and has the properties of high speed, high strength, and remarkable improvement on impermeability, corrosion resistance, wear resistance, freeze-thaw resistance, bonding and the like. Under the condition of meeting the D400 load-bearing requirement, the common concrete needs 200mm in thickness, while the resin concrete only needs 20mm in thickness, so that the weight of the resin concrete is reduced by 85 percent.
