Description

TECHNICAL FIELD

[0001] The present application relates to a method for eliminating the abnormal sound of a sinking-prevention well lid. BACKGROUND

[0002] The sinking-prevention well lid is widely used in urban roads, and includes a cover plate and a well seat. A groove is arranged on the well seat, and a rubber pad is placed in the groove. When the cover plate covers the well seat, the rubber pad separates the cover plate and the bottom surface of the well seat groove. Thus, when the vehicle tire presses the cover plate, the cover plate presses the rubber pad, and the rubber pad is compressed to press the bottom surface of the well seat groove. Thus, the rigid cover plate directly collides with the rigid bottom surface of the well seat groove to avoid the situation that the rigid cover plate directly collides with the rigid bottom surface of the well seat groove to produce a loud abnormal sound.

[0003] However, in a road section with heavy traffic, the rubber pad is easily damaged after being pressed many times. When the vehicle tire presses the cover plate, the damaged rubber pad loses the function of separating the cover plate and the bottom surface of the well seat groove. The rigid cover plate directly collides with the rigid bottom surface of the well seat groove to produce a loud abnormal sound. The loud abnormal sound seriously affects the mood of the driver in the vehicle, is not conducive to safe driving, and also makes the surrounding people frightened, which seriously affects the mood and is not conducive to health. Therefore, the more busy the road section is, the more frequently the damaged rubber pad needs to be replaced by the management unit, and even the rubber pad needs to be replaced every week, which brings a great burden to the management unit.

[0004] Patent document (CN2012204922601) discloses a multifunctional well lid. The well lid includes a well lid body and a support. A rubber slot is arranged on the inner side of the support, and a rubber pad is arranged in the rubber slot. Two or more C-shaped spring locks are arranged on the inner side of the well lid body. One end of the C-shaped spring lock is fixed on the spoke support rib on the inner side of the well lid, and the other end of the C-shaped spring lock is provided with a wedge-shaped block. A slot is arranged on the edge of the support corresponding to the wedge-shaped block. The multifunctional well lid claims that the C-shaped spring lock tightly adheres to the support to avoid the vibration and noise caused by the collision between the well lid and the support. However, the C-shaped spring lock is located in the well, and when the cover plate is covered, the C-shaped spring lock cannot be accurately installed and tightly buckled through the visual observation of the eyes. Therefore, the abnormal sound still exists when the vehicle passes through the well lid, and the rubber pad also needs to be frequently replaced due to frequent damage. Therefore, it is urgent to develop a method for eliminating the abnormal sound of the well lid for a long time through one-time installation. SUMMARY

[0005] In order to solve the problems that the rubber pad in the well seat groove is easily damaged by the vehicle pressing the cover plate to cause the rigid cover plate to directly collide with the rigid bottom surface of the well seat groove to produce a loud abnormal sound, and the rubber pad needs to be frequently replaced, the present application provides a method for eliminating the abnormal sound of a sinking-prevention well lid.

[0006] This invention relates to a method for eliminating abnormal noise from anti-settlement manhole covers. The anti-settlement manhole cover includes a cover plate and a base with a groove. The method includes the following steps:

[0007] 1) Place construction barriers around the anti-settlement manhole covers that make abnormal noises when vehicles drive over them;

[0008] 2) Open the cover plate of the anti-settlement manhole cover and remove the damaged rubber pad placed in the groove of the manhole seat;

[0009] 3) Remove rust from the well seat groove and clean the groove;

[0010] 4) Apply industrial repair agent thoroughly to the cleaned groove;

[0011] 5) Embed a steel wire rope with a diameter less than or equal to the depth of the groove into the groove and ensure it is in full contact with the industrial repair agent, pressing it firmly.

[0012] 6) After installing an isolation layer to prevent the cover from contacting the industrial repair agent, replace the cover.

[0013] 7) Remove the construction enclosure;

[0014] 8) Conduct on-site vehicle rolling tests to confirm that the anti-settlement manhole cover makes no abnormal noise.

[0015] A steel wire rope is a helical bundle of steel wires twisted together according to certain rules, meeting specific mechanical properties and geometric dimensions. This invention replaces rubber pads by placing the steel wire rope within a groove and fixing it with an industrial repair agent. This prevents the steel wire rope from being damaged when a vehicle runs over it and the cover plate then runs over the rope, allowing it to be used for at least three years without replacement. Furthermore, although the individual steel wires in the rope are rigid, the rope as a whole is not rigid but elastic; that is, the wires are not fixed in place. Thus, when a vehicle runs over the cover plate and the cover plate then runs over the steel wire rope, a small displacement occurs between the wires, allowing each wire to cushion the impact of the cover plate. This prevents noise from the cover plate pressing against the steel wire rope, from the steel wire rope pressing against the bottom of the groove, and from the cover plate directly colliding with the bottom of the manhole cover groove. Therefore, the steel wire rope possesses both the cushioning properties of a rubber pad and the durability that a rubber pad lacks.

[0016] Since the groove depth of the well seat is usually 0.8cm, 1cm, or 1.2cm, the diameter of the wire rope can be selected from the corresponding 0.8cm, 1cm, or 1.2cm. The diameter of the wire rope should not exceed the groove depth, and it is preferable that the diameter of the wire rope is consistent with the groove depth.

[0017] In step 3), the rust is removed by grinding with an angle grinder.

[0018] In steps 4) - 6), the industrial repair agent is a mixed agent of the mixed A agent and B agent.

[0019] In step 5), the difference between the length of the groove and the length of the steel wire rope in the groove is less than 5 cm. In this way, the cover plate can be further ensured not to collide with the bottom surface of the well seat groove when the cover plate is rolled by the vehicle. If the above difference is greater than 5 cm, it means that the steel wire rope is too short, and a large part of the groove is not filled with the steel wire rope, and after the cover plate is rolled by the vehicle, the cover plate is easy to collide with the part of the groove not filled with the steel wire rope, and the noise is generated. Preferably, the length of the steel wire rope in the groove is consistent with the length of the groove where it is located.

[0020] In step 6), the isolation layer is a plastic bag, the cover plate is covered with the plastic bag to isolate the cover plate from the industrial repair agent, and the part of the plastic bag above the cover plate is removed after the cover plate is covered. In this way, the isolation layer is simple and convenient to set up.

[0021] Beneficial effects: The present application is suitable for the anti-settling well cover with a circle of grooves in the well seat. Unexpectedly, the cover plate is isolated from the bottom surface of the well seat groove by placing the steel wire rope instead of the rubber pad in the well seat groove. When the cover plate is rolled by the vehicle, the steel wire rope can play a buffering role, which can avoid the collision between the well cover and the steel wire rope, avoid the collision between the steel wire rope and the bottom surface of the groove, avoid the direct collision between the cover plate and the bottom surface of the groove, and generate noise, and will not be crushed, with a very long service life. Through one-time installation, the noise can be eliminated for several years, which not only avoids the trouble of drivers, surrounding people and management units, but also greatly saves various costs caused by frequent replacement of rubber pads, and produces unexpected effects.
