Abstract

The utility model discloses a municipal drain pipe, including outer pillar and interior pillar, the inside of interior pillar setting pillar outside, it still includes buffer layer, armor no. 1 and armor no. 2, the outer terminal surface of armor no. 1 and the laminating of the interior terminal surface of outer pillar, the interior terminal surface of armor no. 2 and the laminating of the outer terminal surface of interior pillar, the buffer layer sets up at armor no. 1 and armor between two, and its terminal surface with armor no. 1 and armor no. 2 correspond is laminated, the equipartition has a plurality of buffering cavity in the buffer layer. The advantage is: the utility model has the advantages of simple structure and have than strong compressive capacity.

Description

Municipal drain

Technical field

This utility model belongs to municipal drainage facility technology field, especially relates to a kind of municipal drain.

Background technology

At present, in the municipal drainage system of avenue, drain pipe is indispensable important component part, and it is the basic component units in drainage network system and connects hinge.Existing drain pipe is the most buried in underground, and in use, the current meeting extrusion pipe inwall in pipeline, inwall be caused compression by this meeting, and it easily causes drain pipe explosion, and owing to drain pipe is the most buried in underground, it repairs the most inconvenient；It is therefore desirable to improved.

Summary of the invention

The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that a kind of municipal drain, it has simple in construction and has the feature of stronger anti-pressure ability.

To achieve these goals, this utility model be the technical scheme is that a kind of municipal drain, and including outer pillar and inner protective tube, described inner protective tube is arranged on the inside of outer pillar；It also includes the inner face laminating of cushion, armor one and armor two, the outer face of described armor one and outer pillar, the outer face laminating of the inner face of described armor two and inner protective tube；Described cushion is arranged between armor one and armor two, and its end face laminating corresponding with armor one and armor two；Several buffer cavity it are evenly equipped with in described cushion.

The outer face of described outer pillar is coated with corrosion-resistant coating, and the inner face of described inner protective tube is coated with corrosion-resistant coating.

The number of described buffer cavity is 3～20.

Described cushion is molded with by quality of rubber materials, and described armor one and armor two are molded with by aluminum alloy material.

After using said structure, this utility model is the most advantageously: simple in construction of the present utility model, the buffer cavity of cushion and inside thereof is under coordinating with the use of armor one and armor two, drain pipe can be allowed to have preferably anti-pressure ability, extend its service life；Outer pillar can allow outer pillar and inner protective tube have preferably anticorrosive property with the corrosion-resistant coating on inner protective tube, is effectively improved its ruggedness.

Accompanying drawing explanation

Fig. 1 is planar structure schematic diagram of the present utility model.

Detailed description of the invention

The following stated is only preferred embodiment of the present utility model, the most therefore limits protection domain of the present utility model, further illustrates this utility model with embodiment below in conjunction with the accompanying drawings.

Embodiment, as shown in Figure 1: a kind of municipal drain, including outer pillar 10, inner protective tube 20, cushion 11, armor 1 and armor 2 13, outer pillar 10 and inner protective tube 20 all use plastic material to make, and inner protective tube 20 is arranged on the inside of outer pillar 10.Cushion 11 uses quality of rubber materials to be molded with, and it is arranged between armor 1 and armor 2 13, i.e. fit with the inner face of armor 1 in the outer face of cushion 11, the outer face laminating of the inner face of cushion 11 and armor 2 13；Being evenly equipped with several buffer cavity 14 in cushion 11, the number of buffer cavity 14 is 3～20, selects 15 in the ordinary course of things and is preferred；Cushion 11 and buffer cavity thereon 14 can buffer outer pillar 10 and the pressure of inner protective tube 20, prevent it from bursting.Armor 1 and armor 2 13 are molded with by aluminum alloy material, the inner face laminating of the outer face of armor 1 and outer pillar 10, the outer face laminating of the inner face of armor 2 13 and inner protective tube 20；Armor 1 and armor 2 13 can improve preferably comprcssive strength, and it can extend the service life of drain pipe.The outer face of pillar 10 is coated with corrosion-resistant coating outside, and the inner face at inner protective tube 20 is coated with corrosion-resistant coating, and corrosion-resistant coating can allow outer pillar 10 and inner protective tube 20 have preferably anticorrosive property, is effectively improved its ruggedness.
