Description

A protect cover for buried pipe}

The present invention relates to a buried pipe protective device for protecting the joints of buried pipes buried underground, more specifically, to prevent the leakage and leakage of buried pipes buried underground, such as water, sewage pipes or gas pipes while the joints from earth pressure or external pressure A buried tube protector is provided for dispersing and protecting the stress concentration of a metal.

In general, buried pipes such as water, sewage pipes, gas pipes, etc., which are branched underground, are branched by welding, fusion, and bonding, which are branched around the main pipe, but these buried pipes are used underground for a long time. The cracks and crevices were generated by stress concentration due to earth pressure or external pressure at the joints that are structurally weak at.

In other words, due to the external pressure or the internal pressure of the contents themselves, the connection state of the buried pipe easily becomes poor, and leakage and leakage of the contents occurs through the gaps between these joints, so that the clean water of the water source is not supplied properly before being used. In addition to the economic loss of water leaked out of the underground water supply pipe as it is, the dirty soil and wastewater from the sewage source contaminated the soil and water quality of the sewer pipe, which is a buried pipe. The explosion accidents were frequently caused by the leakage of high pressure gas.

However, since the buried pipes are underground buried chains, it is difficult to check the joints between these main pipes and the branch pipes themselves, and it is impossible to prevent the joints of the buried pipes from being damaged due to stress concentration by earth pressure or external pressure. However, there was a problem that there was no special countermeasure against environmental pollution and large safety accidents caused by leakage and leakage of buried pipe.

Therefore, the present invention was devised to solve the structural problems of the conventional buried pipes. The joints of buried pipes buried underground such as water, sewage pipes or gas pipes are stress-damaged by earth pressure or external pressure and internal pressure. The purpose is to provide buried pipe protective equipment to reduce environmental pollution and large safety accidents caused by leakage and leakage of joints.

In order to achieve the above object, the present invention, the upper cover and the lower cover of the metal material is formed in a semi-circular shape so that the branch pipe is fastened to each other and bolted to the outer surface of the main pipe to be joined joint, these upper cover and lower Each of the connecting ribs protruding from both ends of the cover is formed with a bolt hole through which bolts and nuts can be fastened and fixed at regular intervals, and penetrated so that the branch pipe can be inserted into the center of the upper cover. The cylindrical branch cover is characterized in that the protrusion is formed by welding.

Hereinafter, described in detail preferred embodiments of the present invention by the accompanying drawings as follows.

1 is a view illustrating a state of use of the buried pipe protective device of the present invention is fixed to the joint portion of the main pipe 30 and the branch pipe 32 is a buried pipe, Figure 2 is a state diagram of the buried pipe protective equipment according to the present invention It is shown.

As shown in FIG. 2, the buried pipe protector of the present invention, which is fastened to the joints of the buried pipe buried underground, is bolted to the upper cover 10 so that the bolts can be fastened to each other on the outer surface of the main pipe 30. ) And the lower cover 20 is formed in the center of the upper cover 10, the cylindrical branch cover 32 penetrated so as to be assembled to the outer surface of the branch pipe 32 is formed.

That is, the upper cover 10 and the lower cover 20 including the branch cover 15 are formed of stainless steel having excellent corrosion resistance so as not to be corroded while being buried in the buried pipe and buried underground with the buried pipe. The upper cover 10 and the upper cover 10 are formed integrally by welding, while the upper cover 10 and the lower cover 20 are symmetrically fastened to each other on the outer surface of the main pipe 30 in a semicircular shape. The connecting ribs 12 and 22 are protruded from each other so as to be integrally structured by bolting to each other, and the plurality of bolts 24 are fastened to the connecting ribs 12 and 22. The bolt holes 11 and 21 are penetrated at regular intervals so as to be fixed to the nut 23.

On the other hand, these semi-circular upper cover 10 and the lower cover 20 is formed slightly larger than the outer diameter of the main pipe 30, the cylindrical branch cover 15 is also formed slightly larger than the outer diameter of the branch pipe 32, At this time, the outer diameter of these buried tube protective equipment is not so large compared to the outer diameter of the buried pipe can be assembled and fixed to be in close contact with each other after shaking assembling.

The buried pipe protector of the present invention configured as described above is fastened and bolted to a joint portion of the main pipe 30 and the branch pipe 32 made of a polyester material fused or bonded as shown in FIG. 1.

First, the branch cover 32 of the upper cover 10 is inserted into the outer surface of the branch pipe 32 prior to the joint joint of the branch pipe 32 to the main pipe 30. ) And primary joint caulking of the main pipe 30 is treated with primary caulking (silicon) to maintain the watertightness and airtightness, while the secondary forming (urerhane) 25 with excellent rebound elasticity Finish through

Then, accessing the branch cover (15) pre-fastened to the joint portion of the buried pipe for the temporary assembly of the upper cover (10) of the branch cover (15) to the upper surface portion of the main pipe (30), the main pipe ( The lower cover 20 is temporarily assembled to the lower surface portion of the lower surface 30 to connect the connecting ribs 12 of the upper cover 10 and the connecting ribs 22 of the lower cover 20 to the corresponding bolts 24. By bolting through the fastening of the nut and the nut 23, the joint portion of the buried pipe stress concentrated by earth pressure or external pressure and its internal pressure can be safely protected by the buried pipe protective device.

As described above, according to the buried pipe protective device of the present invention, the joints of buried pipes buried underground such as water, sewage pipes, and gas pipes can be prevented from being stressed and broken due to stress concentration due to earth pressure, external pressure, and internal pressure. It can reduce the economic loss of wasteful water resources as it leaks through the cracks and crevices of the joints and the clean water of the water supply and the dirty water and sewage. In particular, large safety accidents due to leakage of high pressure gas can be structurally reduced.

In addition, the joint portion of the buried pipe can be protected against stress concentration as well as external impact, and consequently, the effect of extending the service life of the buried pipe is provided.
