Description

Impervious reinforced concrete drain pipe and production process thereof

Technical Field

The invention relates to the technical field of reinforced concrete pipelines, in particular to an anti-permeability reinforced concrete drain pipe and a production process thereof.

Background

With the rapid advance of urbanization, China builds or plans to build a plurality of sewage treatment plants in large and medium cities, a large amount of industrial wastewater and domestic sewage enter the sewage treatment plants for centralized treatment through drain pipes, the drain pipes mostly use reinforced concrete drain pipes which generally comprise concrete, reinforced concrete or High Density Polyethylene (HDPE) materials, and the compressive strength of the reinforced concrete water pipes is higher than that of other types, so that the reinforced concrete water pipes are suitable for the field requiring larger pipe diameters. The connector types of the existing reinforced concrete water pipe generally comprise a tongue-and-groove type, a flat type and a socket type, and the specific application scenes are different according to different structures;

in the foreseeable future, cement concrete will remain the most dominant building material with no alternatives. From this perspective, the sustainable development of the construction industry is closely related to the performance and durability of concrete. That is, concrete must meet the socio-economic development requirements with minimal material consumption and environmental impact. In this regard, the development of ultra-high performance concrete is undoubtedly the most promising solution;

the reactive powder concrete is a novel cement-based composite material with ultrahigh compressive strength, high durability and high toughness. The reactive powder concrete as a novel ultra-high performance concrete has two compression strength grades of 200MPa or 800MPa, and the bending strength is 30-60 MPa, so that the high brittleness of the high performance concrete is effectively overcome, and the performance is excellent. The process of the active powder concrete with the strength grade of 200MPa is similar to that of common concrete, and the application prospect is wide;

the reactive powder concrete has ultrahigh strength, excellent durability and good ductility and energy consumption capability. These excellent properties lead to reactive powder concrete structures and structures having very high strength to weight ratios, outstanding durability and good seismic performance. As a high-tech concrete, at present, there are two main factors that hinder the mass application of reactive powder concrete: the first is the higher cost of the unilateral material. The cement consumption of the active powder concrete is large, and a high-efficiency water reducing agent, steel fibers and the like are required to be added, so that the material cost is increased; the other is that the member needs to be thermally cured, the high activity of the active powder concrete material can be quickly and fully exerted at a certain curing temperature, and researches show that the compressive strength of the active powder concrete is improved by more than 30 percent compared with that of the active powder concrete which is cured in hot water at 90 ℃ for 48 hours. Therefore, under the existing conditions, the active powder concrete should be combined with other materials in the civil engineering field in a prefabricated member mode, so that the ultrahigh compression resistance and good ductility of the active powder concrete are fully exerted, and the active powder concrete can be considered to replace steel at a reasonable position, thereby showing the strength/cost ratio advantage of the active powder concrete;

the confined concrete structure represented by the steel pipe concrete column has been intensively studied and widely used in the past fifty years. The steel tube concrete column is formed by filling concrete in a steel tube to form a steel-concrete combined column. The basic principle of the combined column is that the steel pipe is utilized to provide lateral restraint for the concrete in the core area, so that the concrete is in a three-dimensional stressed stress state, and the compressive strength and the compressive deformation capacity of the combined column are improved. In addition, the concrete filled inside provides a supporting effect for the steel pipe, the geometric stability of the wall of the steel pipe is enhanced, the instability mode of the steel pipe is changed, the bearing capacity of the steel pipe is improved, and meanwhile, the fire resistance limit of the steel pipe can be improved due to the existence of the concrete inside. In addition, in the construction process, the steel pipe is used as a template for pouring concrete in the core area, so that the construction is facilitated.

The existing reinforced concrete pipelines mostly directly adopt at least six bolts in a circle to implement jacking splicing combination, the six bolts in the jacking need to be sequentially screwed at least during splicing combination, the operation is troublesome and labor-consuming, and the operation is difficult due to space local shortage when the bolts contacting with filled pit soil at the bottommost are screwed, in addition, most of the pipelines lack auxiliary glue filling mechanisms, so that the sealant can not be uniformly filled in the butt joint gap between the two pipelines, and the sealing and anti-leakage performance of the pipelines is influenced.
