Description

Concealed decorative access hole

Technical Field

The utility model relates to the technical field of access ports, in particular to a concealed decorative access port.

Background

In the current urban planning, along with the promotion of the urban process, the urban land is tense, and the pipelines of electric power, communication, fuel gas and water supply and drainage are usually arranged underground with the city so as to save ground space; generally through building utility tunnel in the city underground, collect various engineering pipelines such as electric power, communication, gas and water supply and drainage in an organic whole and set up in the utility tunnel, in order to conveniently overhaul the rescue, also can be equipped with special access opening and make things convenient for the staff to get into inside maintenance and detection to this guarantee city safety and orderly operation, make ground city view more succinct simultaneously.

However, the existing access opening has the following remarkable defects:

1. The structure of current access hole is mainly circular, need cut out circular with mounting material during actual construction, and the crushed aggregates of being cut hardly bonds firmly, has increased the degree of difficulty for site operation, and its surface is not pleasing to the eye after the access hole construction.

2. The existing access hole is structurally characterized in that the upper cover of the access hole is inlaid on the outer edge and the inner side of the base, sundries such as silt and dust can block the joint seam between the upper cover and the base in daily use, gaps are easy to be greasy and dead by silt, so that the access hole is difficult to open, when the access hole is overhauled, a large hammer is required to be used for tamping the cover plate to crack the silt, an iron hook is used for hooking the access hole cover plate, surrounding decoration materials can be shocked and damaged in the tamping and smashing process, an maintainer cannot maintain the access hole, a window breaking effect of the decoration materials is caused, and the access hole is long in time, so that pedestrians can be tripped easily.

3. Traditional access hole adopts cast iron to make in the material, adopts the straight wall often, and the intensity of thicker access hole of wall thickness just can reach national standard requirement, and whole heavier and can cause the material waste. The diameter of a common outdoor cast iron overhaul hole is generally 700-900, and the cast iron manhole cover is very heavy and is difficult to open; some stainless steel decorative access holes are arranged above the cast iron access holes for urban attractiveness, the square access holes are made of water permeable bricks or stones bonded in the stainless steel frames, the size of the square access holes is larger than that of cast iron manhole covers, the weight of the square access holes is multiplied, the stainless steel frames are usually provided by stainless steel suppliers, the sizes of enterprises are different, the manufacturing level is good, the stainless steel manufacturers do not have structural checking capability, the rigidity of products is insufficient, and after the pavement is driven, decoration materials on the manhole covers are crushed. These decorative access openings also require tamping and dragging when opened, which can also cause a window breaking effect of the decorative material.

4. When in use, after the upper cover of the access hole is opened, no special person manages, and the hidden trouble is easy to generate when the device is placed at will.

5. Most of the existing access ports are not locked by locks, so that the upper cover part is easy to lose, and accidents are caused.

In summary, the present inventors have found that at least the following technical problems exist in the prior art:

the existing structure of the access opening has the problems of inconvenient construction and installation and daily maintenance and use.
