Problems solved by technology

This construction method will cause defects such as poor sealing and low strength at the joints of rainwater pipe joints. The use of rectangular supports will easily cause deviations in the position of rainwater pipes. At the same time, pouring concrete at the bottom of rainwater pipes will increase construction costs and slow construction speed.
[0004] In view of this, in order to solve the problems of slow construction progress, high cost, and poor sealability of rainwater pipes in traditional construction methods, it is urgent to invent a new rainwater pipe structure with fast construction progress, low cost, and easy construction quality.

Abstract

The invention relates to the technical field of municipal pipeline engineering, and particularly discloses a rainwater pipeline structure and a construction method thereof. The rainwater pipeline structure comprises prefabricated rainwater pipe sections. The rainwater pipeline structure is characterized in that the adjacent prefabricated rainwater pipe sections are connected end to end through polysulfide sealant, and the outer sides of the joints are coated with cement mortar and wound with steel wire meshes; the bottom of each prefabricated rainwater pipe section is provided with prefabricated supports which are provided with an arc-shaped contact surfaces, and the contact surfaces of the prefabricated supports and the prefabricated rainwater pipe sections are provided with the cement mortar. According to the rainwater pipeline structure and the construction method thereof, a reasonable combination mode between the prefabricated rainwater pipe sections and the prefabricated supports is utilized, the construction cost is low, construction is convenient, the construction speed is high, the construction quality is easy to guarantee, and then the effect of reducing the cost is achieved.

Description

(1) Technical field [0001] The invention relates to the technical field of municipal pipeline engineering, in particular to a rainwater pipeline structure and a construction method thereof. (2) Background technology [0002] With the rapid development of urbanization, as an important urban infrastructure, the construction of rainwater pipe network has made great progress. However, because the rainwater pipe network has the characteristics of large short-term flow, the investment cost of the corresponding pipe network system accounts for a considerable proportion of municipal investment. Therefore, the maximum optimization design of the rainwater pipe network will reduce a lot of investment costs and achieve the best economic benefits. [0003] Prefabricated reinforced concrete rainwater pipes have the characteristics of high strength and convenient construction, and are widely used in municipal engineering. The traditional construction process is to prefabricate the rectan...
