Abstract

A cement pipe connection structure is that a glass fiber reinforced plastic sleeve is sleeved at the periphery of the connection position of adjacent cement pipes, the glass fiber reinforced plastic sleeve is made of drinking water level resin, and a sealing rubber ring is sleeved at the periphery of the glass fiber reinforced plastic sleeve. The cement pipe connection structure uses the glass fiber reinforced plastic sleeve to substitute an existing steel sleeve. When necessary, the sealing rubber ring is sleeved outside the glass fiber reinforced plastic sleeve. The cement pipe connection structure has the following advantages that the glass fiber reinforced plastic sleeve is high in strength so as to be capable of bearing certain pressure and well protect cement pipes; the glass fiber reinforced plastic sleeve is good in corrosion resistance and can effectively reduce maintenance cost; due to the fact that the glass fiber reinforced plastic sleeve is made of drinking water level resin, secondary pollution on water in the cement pipes is prevented from being generated; compared with the traditional steel sleeve, the manufacture cost is reduced by more than 15%; and the sealing rubber ring has good buffer function and can prevent the glass fiber reinforced plastic sleeve from being damaged when being pressed.

Description

The cement pipe linkage structure

Technical field

The utility model belongs to urban operating mechanism construction technique field, particularly relates to a kind of cement pipe linkage structure.

Background technique

Water supply aqueduct in town and country adopts cement pipe more at present, and it is a kind of prefabricated pipeline that utilizes cement and reinforcing bar to make.If but this piping laying is in the environment of some pressurizeds, for example during the below of highway, building, it is easy to be damaged, although can carry out repairing treatment in the later stage, takes time and effort; On the other hand, one of significant points of leaking occurs because the slit of pipeline and pipeline connection is pipeline, in case leak, other material in the soil, just might enter into water such as heavy metal ion, thereby water generates is polluted, therefore, airtight particularly important between pipeline and the pipeline.At present commonly used the method for steel casing pipe sleeve in adjacent concrete duct joint solved the pipe leakage problem, but that shortcoming is the cost of steel sleeve pipe is high, mounting process is complicated, and does not have buffer function, so can not effectively protect cement pipe.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of cement pipe linkage structure that can strengthen local strength and seal, water proofing property.

In order to achieve the above object, the cement pipe linkage structure that the utility model provides is that at the outer peripheral surface of adjacent cement pipe joint cover a glass reinforced plastic sleeve, glass reinforced plastic sleeve to be arranged be to adopt other resin of potable water level to become.

Also overlap on the outer peripheral surface of described glass reinforced plastic sleeve a sealing rubber ring is arranged.

The cement pipe linkage structure that the utility model provides is to replace existing steel sleeve pipe with glass reinforced plastic sleeve, and puts a sealing rubber ring in the outside of glass reinforced plastic sleeve in case of necessity again, and it has the following advantages:

(1) intensity of glass reinforced plastic sleeve is higher, therefore can bear certain pressure, so can protect preferably cement pipe;

(2) good corrosion resistance of glass reinforced plastic sleeve can effectively reduce later maintenance cost;

(3) because glass reinforced plastic sleeve itself is to adopt other resin of potable water level to become, therefore can be to the water generates secondary pollution in the cement pipe;

(4) fabricating cost is low, compares with traditional steel sleeve pipe, and fabricating cost is low more than 15%;

(5) sealing rubber ring that is enclosed within the glass reinforced plastic sleeve outside has preferably buffer function, occurs in the time of can preventing the glass reinforced plastic sleeve pressurized damaging.

Description of drawings

The cement pipe linkage structure schematic diagram that Fig. 1 provides for the utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments the cement pipe linkage structure that the utility model provides is elaborated.

As shown in Figure 1, the cement pipe linkage structure that the utility model provides is that at the outer peripheral surface of adjacent cement pipe 1 joint cover a glass reinforced plastic sleeve 2, glass reinforced plastic sleeve 2 to be arranged be to adopt other resin of potable water level to become.

Also overlap on the outer peripheral surface of described glass reinforced plastic sleeve 2 sealing rubber ring 3 is arranged.

The cement pipe linkage structure installation method that now the utility model is provided is described below: when cement pipe to be installed 1 is positioned at the larger zone of pressurized, when being positioned at the below of highway, building, at first the outer peripheral surface at glass reinforced plastic sleeve 2 puts a sealing rubber ring 3, then will be enclosed within glass reinforced plastic sleeve 2 one ends of sealing rubber ring 3 front end surface of a rear cement pipe 1, afterwards the rear end of last cement pipe 1 will be inserted in inner the getting final product of the other end of glass reinforced plastic sleeve 2.If cement pipe to be installed 1 is positioned at the less zone of pressurized, can only use glass reinforced plastic sleeve 2, and need not at its outer installment sealing rubber ring 3, the connecting means between glass reinforced plastic sleeve 2 and the cement pipe 1 is the same, therefore repeats no more here.

Claims

1. cement pipe linkage structure, it is characterized in that: described cement pipe linkage structure is that at the outer peripheral surface of adjacent cement pipe (1) joint cover a glass reinforced plastic sleeve (2), glass reinforced plastic sleeve (2) to be arranged be to adopt other resin of potable water level to become.

2. cement pipe linkage structure according to claim 1 is characterized in that: on the outer peripheral surface of described glass reinforced plastic sleeve (2) also cover a sealing rubber ring (3) is arranged.
