The present invention relates to a damper cover of a civil engineering tunnel cavity, such as a road, and more particularly, to a damper cover of a civil engineering tunnel cavity, such as a road, to fix the cover for the tunnel cavity through a hinge method.

In general, one side or both sides of the tunnel is provided with a common pit for the purpose of jointly receiving the buried goods, such as electricity or communication cables, gas pipes, water pipes and sewer pipes, and the buried material in the cavities can be checked in a certain section of the hollow ward. The cover is provided to be raised to a step formed at the top of the cavity.

In this way, the cover that is covered on the upper part of the cavity is covered to have a sealing property so that foreign matters, etc., from the outside are not prevented from being damaged or broken in the cavity, and the inspector or the like can sufficiently withstand the load even when the passenger passes. It is common for most of them to be made of concrete.

In addition, the handle is installed so that the inspector can easily open for inspection, etc. during the production of the concrete, when the handle is formed as a groove formed integrally on both sides of the cover, the top of the cavity sphere where the cover is raised Had to increase the width of the step formed in the.

This is because the cover can be sealed when covered with the upper part of the cavity.

In addition, when the handle is formed to have a sealability without forming an integral groove on both sides of the cover as described above, the cover is not only cumbersome but also has a complicated structure.

And, above all, the cover installed on the upper part of the conventional cavity is mainly made of concrete as described above, when the inspector wants to open the cover to check the buried material, etc. As a separate worker is required, a problem arises in that a large number of personnel must be mobilized.

Utility model registration 0418812 (tunnel joint cover) was developed to solve the above problems.

As shown in Figure 1 and 2, the cover 200 for the tunnel cavity is formed a plurality of support portions (12a) by the known forming in the longitudinal direction for the bearing force and the slip on the upper surface plate 12 And, before and after between the intermediate support portion to form a gripping hole (12b) so that the inspector can easily grip and open and close, the side plate 14, which is mounted on the stepped jaw is supported on the upper surface plate 12 The main body 10 of the metal material is formed integrally bent in the bottom surface formed with the gripping hole (12b) of the upper plate 12, the inflow preventing member 20 is fixed to the foreign matter through the gripping hole to be hermetically fixed And, the front and rear ends of the main body 10 is composed of the respective closing plate 30 is fixed through the normal welding or the like to correspond to the upper surface plate and the side plate.

However, since the conventional tunnel cavity cover has a structure to be seated on the cavity, there is a problem that the work time and a lot of manpower is required because the inspector has to stand on the side of the tunnel to lift the cover to check the buried material.

In addition, there is another problem that can not be prepared for fire because it is simply formed of a metal cover.

The present invention is to solve the above problems, by fixing the cover for the tunnel cavity ball through the hinge method when the operator lifts only one side during operation by being automatically lifted by the damper to open the work time can be relatively shortened. It is also an object of the present invention to provide a damper cover of a tunnel tunnel for civil engineering, such as a road, which enables inspection to be carried out with a small manpower.

In addition, the present invention is to provide a damper type cover of civil engineering tunnel joints, such as a road to attach the insulation to the bottom of the cover, to form a reflector on the upper surface to protect the interior buried in the event of a fire, and to induce the eyes of the inspector. There is a purpose.

It is another object of the present invention to provide a damper type cover of a civil engineering tunnel cavity such as a road to form a locking member on the cover to prevent theft of the cover.

Here, the locking groove 125 may be formed in the central portion of the side instead of the lock ring 123 as shown in FIG.

In addition, the cover 130 is seated between the first frame 110 and the second frame 120 to be seated on the upper end of the cavity (1) to the bottom plate is open with a zinc hot-dip galvanized metal material for corrosion protection It is formed in a rectangular tubular shape, the anti-slip projection 131 is formed to protrude in the form of a line or dot on the upper surface, the handle 132 of the Diagonal shape is welded to the central portion on one side of the upper surface, the side of the handle 132 The lock 133 is formed, the reflective tape 134 is attached to one side of the upper surface to guide the eyes of the inspector, the deformation preventing rib 135 is formed in a lattice form to prevent deformation on the bottom surface and withstand load, The first hinge jaw 136 is formed on both sides, and a heat insulating material 137 that blocks heat on the bottom is attached by an adhesive or the like.

Here, the cover 130 is a handle hole 132-1 is formed in place of the handle 132, as shown in Figure 6 and 7, the handle ring 132-3 may be inserted and fixed, T A handle ring formed in a shape may be formed.

Here, the cover 130 is formed with a locking member 133-3 having a key hole 133-1 at the center of one end of the upper surface instead of the lock 133 as shown in FIGS. 8 and 9. The locker 133-5 may be inserted into the locking groove 125 of the second frame 120, and the locker hole 133-7 is formed at the side of the locker 133-5.

Here, the cover 130 may be formed in the form of steel grating used for rainwater catchment of the general road rather than the closed type according to the selection.

On the other hand, the hinge 140 is coupled by a bolt or welding between the cover 130 and the first frame 110 to rotate the cover 130.

Then, the damper 150 is hinged by one side of the first hinge jaw 136 and the hinge shaft 153 of the cover 130 to rotate the cover 130, the other side of the second hole of the cavity (1) It is hinged by the hinge jaw 151 and the hinge shaft 153.

Hereinafter, with reference to Figures 3 to 10 attached to the installation process and action of the damper cover of the tunnel tunnel for civil engineering, such as road according to the present invention.

First, block-out is performed at a corresponding position so that the first anchor 111 of the first frame 110 and the second anchor 121 of the second frame 120 are inserted into the step 3, and then the first frame. After inserting the first anchor 111 of the 110 and the second anchor 121 of the second frame 120, respectively, at the blocked-out position, the mortar is filled to fill the step with the first frame 110 and the second frame. Fix 120. At this time, it is preferable that the lock ring 123 or the locking groove 125 is formed in advance in the second frame 120 at a predetermined interval, and the locker 133-5 is inserted when the locking groove 125 is formed. Preferably, the stepped side of the corresponding position is blocked out to a certain depth.

When the fixing of the first frame 110 and the second frame 120 is completed, the prefabricated cover 130 is fixed to the first frame 110 by a bolt or a welding method through a hinge 140 to be rotatable. Let's do it. At this time, the fixing position of the cover 130 is preferably fixed to a height capable of rotating in the first frame (110).

The upper end of the damper 150, that is, the piston, is coupled to the first hinge jaw 136 and the hinge shaft 153 of the cover 130, and the lower end of the damper 150 is coupled to the second hinge of the cavity 1. The jaw 151 and the hinge shaft 153 are coupled to each other.

When the inspector enters the tunnel for checking in the state in which the cover 130 is installed in the cavity 1 in the same manner as described above, the line of sight is guided by the reflective tape 134 formed on the cover 130, and the cover 130 ) Can be pinpointed.

Then, the inspector releases the lock 133, grabs the handle 132 and lifts the cover 130 to rotate in the first frame 110 with the hinge 140 as the axis.

At the same time, while the piston of the damper 150 is raised by pneumatic or hydraulic pressure, the cover 130 is raised as shown in FIG. 10 to open the cover 130 in the cavity 1.

When the inspection is completed and the inspector presses the cover 130 to close the cover 130, the piston of the damper 150 descends and at the same time the damper 150 is connected to the first hinge jaw 136 and the second hinge jaw ( At 151, while rotating around the hinge axis 153, it is lowered to maintain horizontality.

In this state, the inspector combines the lock 133 with the lock ring 123 of the second frame 120 to prevent theft.

Therefore, the cover is fixed to the frame in a hinged manner by using a hinge so that the cover can be rotated on the step, and by using a damper to automatically lift the cover, the inspector only needs to flip the cover without lifting the cover. It can save time.

In addition, since the reflective tape is attached to the cover and the insulation is formed on the bottom, the inspector can be attracted to the inspector in a dark tunnel, and the correct position of the cover can be identified.

In addition, since the lock or the locking member is provided on the cover, the cover cannot be arbitrarily opened except for the inspector, so that theft can be prevented and the buried material can be safely protected.

According to the damper type cover of the tunnel tunnel for civil engineering, such as the present invention is configured as described above, by fixing the cover for the tunnel cavity through the hinge method to reduce the work time by allowing the worker to easily open when lifting only one side when working. It is possible to carry out the inspection with a small amount of manpower, and to attach insulation to the bottom of the cover, to form a reflector on the upper surface, to protect the internal buried material in case of fire, and to induce the eyes of the inspector. The locking member may be formed on the cover to prevent theft of the cover.
