Abstract
The utility model relates to a sewer pipeline, and in particular relates to an underground boost pipe polyester resin concrete pipe. In order to solve the technical problem, the utility model provides a composite glass fiber reinforced plastic push pipe which can act as ground surface excavation underground boost construction under a severe environment. According to the glass fiber reinforced plastic push pipe provided by the utility model, fiber layers are coated on the inner wall and the outer wall of a polyester resin fiber concrete pipe so as to form an intermediate pipe; and outer fiber reinforced layers are compounded again on the inner wall and the outer wall of the intermediate pipe. The glass fiber reinforced plastic push pipe provided by the utility model has the advantages that the glass fiber reinforced plastic push pipe has much high corrosion resistance, besides, the intensity is much higher than that of the traditional cement concrete pipe, and the glass fiber reinforced plastic push pipe is an excellent and chemical-and-physical-resistant novel pipe material.
Description
Technical field
The utility model relates to the utility model and relates to sewer pipe, espespecially underground propulsion tube mylar concrete pipe.
Background technology
Along with promoting the use of of novel tube, traditional cement concrete is not had acid, an alkaline corrosion in anti-soil, the waste water, the requirement of inadaptable dirty, waste water pipe-line system.Mylar concrete pipe in the past, can adapt to city, town and country subsurface disposal sewage and waste water with managing, can be used for ground and dig and underground propelling construction, but these push pipes only are used for general pollution index, those tubing can not satisfy its requirement in the past in the serious situation of industrial pollution.
Summary of the invention
For solving the problems of the technologies described above, we provide a kind of compound glass fiber reinforced plastics push pipe, can dig underground propelling construction as ground under rugged environment and use.
In order to achieve the above object, glass fiber reinforced plastics push pipe of the present utility model, it is that inner and outer wall at the mylar fiber concrete pipe is covered with fibrage, forms intervalve, at the inner and outer wall of intervalve compound outer fiber enhancement layer again.Described fibrage adopts plastics material system to consist of, and is knitted on the mylar fiber concrete pipe with winding method.Described outer fiber enhancement layer is to be made of glass fiber reinforced plastics.Described mylar fiber concrete pipe and fibrage and fibrage are one-body molded by mould.
The utility model has the advantages that: except very high corrosion resistance was arranged, simultaneously intensity was also high a lot of than traditional cement concrete pipe, was the novel tube of a kind of good, chemical resistance and physical property.
Description of drawings
Fig. 1 is pipe face sectional view of the present utility model.
The specific embodiment
As shown in the figure, a kind of glass fiber reinforced plastics push pipe, it surrounds former pipe fitting by some layers of embracing layer and consists of, tool is that structure is as follows: the inner and outer wall at mylar fiber concrete pipe 1 is covered with fibrage 2, form an intervalve, again at the inner and outer wall of intervalve compound coating outer fiber enhancement layer 3 again.Here the mylar fiber concrete pipe 1 of speaking of can be general concrete pipe, also can be the concrete pipe after the polymerization; This patent has adopted by mylar, quartz, quartz sand, fibrous mylar concrete inner tube.Fibrage 2 adopts plastics material system to consist of, and is knitted on the mylar fiber concrete pipe with winding method, and such intervalve is conducive to the compound of outer fiber enhancement layer 3 more.Outer fiber enhancement layer 3 is to be made of glass fiber reinforced plastics, and finished product is more perfect like this.Specific practice is: use respectively injection, lamination, winding, the mode such as centrifugal to make fiber-reinforced layer at internal mold outer wall and external mold inwall, behind the assembling die, in die cavity, add resin, stone, sand, curing agent mixture, Integratively formed, the effect that the pipe inside and outside wall that reaches plays simultaneously anticorrosion and increases pipe intensity is dirty, the inaccessiable characteristic of waste water pipe in the past, is conducive to the construction of dirt, waste way system.
Claims (4)
1. glass fiber reinforced plastics push pipe is characterized in that: it is that inner and outer wall at the mylar fiber concrete pipe is covered with fibrage, forms intervalve, at the inner and outer wall of intervalve compound outer fiber enhancement layer again.
