Problems solved by technology

Although these pipes can achieve the purpose of water delivery to a certain extent, there are some technical defects: 1. Poor impermeability; 2. Poor corrosion resistance; 3. High repair and maintenance costs; 4. Weight of the pipe body Heavy, high transportation and construction costs
[0003] After retrieval, a PCCP pipe was found. On the basis of the existing concrete pipe, a thin steel cylinder was coaxially embedded in the pipe core, and the two ends of the thin steel cylinder were welded on the socket and the socket. Although it can It meets the requirements of good impermeability, but in today's rising steel, it not only increases the cost of raw materials, but also makes the manufacturing process very complicated; and as the pipeline is laid underground for a long time, its steel cylinder will also Corrosion occurs, the maintenance cost is high, and the pipe body is heavy, and the transportation and construction costs are high

Embodiment Construction

[0019] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0020] The steel socket prestressed FRP concrete pipe is composed of a socket 8, a socket 1, a concrete core 3, a prestressed steel wire 6 and a protective layer 7. The socket and the socket are respectively fixed at both ends of the concrete core. 30 longitudinal steel bars 4 are coaxially and uniformly embedded in the concrete tube core, and the two ends of the longitudinal steel bars are respectively fixed on the socket and the socket. The outer wall of the socket can be formed with 1-3 grooves 2 in the radial direction (this Embodiment Figure shows 2 grooves), wherein the outer wall of the concrete tube core is coaxially equipped with a glass fiber reinforced plastic sheath 5, the outer wall of the glass fiber reinforced plastic sheath is...

Abstract

The invention relates to a steel mouthing socket prestressing force glass steel concrete pipe which is composed of a mouthing, a socket, a concrete pipe core, a prestressing force steel wire and a protection layer; the mouthing and the socket are fixedly arranged at two ends of the concrete pipe core respectively, wherein, the outer wall of the concrete pipe core is coaxially and fixedly provided with a fiberglass sheath, the outer wall of which is wrapped with the prestressing force steel wire and fixedly provided with the protection layer. The concrete pipe has the advantages of simple structure, scientific and reasonable design, good durability, corrosion resistance, impermeability, uneven sedimentation resistance, low raw material cost and low construction cost, simple construction process and easy maintenance, and is a steel mouthing socket prestressing force glass steel concrete pipe with higher innovation.

Description

technical field [0001] The invention relates to concrete pipes, in particular to a steel socket prestressed glass reinforced concrete pipe. Background technique [0002] Among the various concrete water pipes currently used in my country, there are mainly self-stressed concrete pipes, prestressed concrete pipes and other concrete drainage pipes with various interface forms according to categories, which are mainly used in municipal, water conservancy, road and bridge, urban water supply and drainage systems, Industrial water pipelines, farmland irrigation, factory pipe networks and deep-covered soil culvert pipes, etc. Although these pipes can achieve the purpose of water delivery to a certain extent, there are some technical defects: 1. Poor impermeability; 2. Poor corrosion resistance; 3. High repair and maintenance costs; 4. The weight of the pipe body Heavy, high transportation and construction costs. [0003] After searching, a PCCP pipe was found. On the basis of the ...
