Description
Technical Field
The utility model belongs to the technical field of municipal facilities, and particularly relates to a concrete invisible well lid device for a permeable concrete pavement.
Background
The pipeline is a blood vessel of a city, is an important component of municipal roads and municipal facilities, and a large number of pipelines are required to be buried along with the roads no matter water, fuel gas, power, information, heat, illumination, traffic monitoring and the like, and various pipelines are required to be provided with a large number of pipeline inspection wells for pipeline maintenance or wiring and the like, and the inspection wells are required to be arranged below the pavement if arranged, so that the pavement is required to be provided with inspection well covers, the travelling comfort is influenced, and certain safety risks exist during pipeline maintenance, so that the general inspection wells are preferentially arranged in the range of slow-moving systems such as the pavement, the non-motor vehicle lanes and the like.
The permeable concrete has the advantages of good integrity, good flatness, excellent water permeability, bright color and the like, and is increasingly applied to chronic systems such as urban road sidewalks and the like. However, arranging a large number of manhole covers on the permeable concrete pavement can definitely greatly influence the integrity and the beauty of the permeable concrete pavement. Therefore, the common well cover is generally replaced by the invisible well cover in the range of the permeable concrete pavement, but the invisible well cover in the current stage is mostly formed by refilling permeable concrete made of the same material by adopting a stainless steel base plate and a frame, because the stainless steel material is low in rigidity, the well cover is easy to deform, the filled permeable concrete is broken, the landscape effect and pipeline overhaul are affected, and a large potential safety hazard exists; meanwhile, as the stainless steel invisible well lid is filled with the permeable concrete and needs a thicker thickness, the stainless steel invisible well lid is generally heavier in weight, is unfavorable for the well lid to be opened and overhauled, and is resisted by a plurality of pipeline maintenance units.
The concrete well cover, especially steel fiber concrete well cover, is popular among vast owners and pipeline maintenance units because of the characteristics of high strength, low cost, good durability and safety, etc., and the common concrete well cover is quite different from the surrounding environment if being used on the permeable concrete pavement, so that the integrity and consistency of the permeable concrete pavement are affected. There is thus an urgent need for a concrete invisible well cover device that combines the excellent characteristics and invisible properties of a concrete well cover and that can be applied to permeable concrete pavement.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provide the concrete invisible well cover device for the permeable concrete pavement, which has good invisible effect and can reduce the manufacturing cost.
According to the technical scheme provided by the utility model, the concrete invisible well lid device for the permeable concrete pavement comprises a well ring and a well lid arranged in the well ring, wherein an opening mechanism is arranged on the well lid, and a metal protection ring is arranged on the outer side surface of the well lid; the well lid comprises a steel fiber concrete layer and a permeable concrete facing layer positioned on the steel fiber concrete layer, wherein a reinforcing mesh sheet is arranged in the steel fiber concrete layer.
Preferably, the opening mechanism on the well lid is an opening hole or a pull ring.
Preferably, the thickness of the steel fiber concrete layer is 5-9 cm.
Preferably, the thickness of the permeable concrete facing layer is 0.5-1.5 cm.
Preferably, the well ring and the well cover are both round or rectangular.
The utility model has the following advantages:
1. according to the utility model, the permeable concrete facing layer is additionally arranged on the steel fiber concrete, so that the appearance of the well lid device is completely consistent with that of the peripheral permeable concrete, and the invisible effect is good;
2. compared with the common stainless steel invisible well lid at the present stage, the utility model can greatly reduce the use of stainless steel, thereby saving the manufacturing cost.

Detailed Description
The utility model will be further illustrated with reference to specific examples.
The utility model relates to a concrete invisible well lid device for a permeable concrete pavement, which comprises a well ring 1 and a well lid 2 arranged in the well ring 1, wherein the well ring 1 mainly plays a role in connecting the well lid 2 with an inspection well, and the well lid device is made of stainless steel, ball-milling cast iron or concrete and other materials, and the stainless steel is taken as an example; the well ring 1 and the well cover 2 can be round, square or other shapes, the shape and the specification can be selected according to the specification shape of the inspection well, the example is 70cm x 70cm rectangle, an opening mechanism is arranged on the well cover 2, and a metal protection ring 3 is arranged on the outer side surface of the well cover 2; the well cover 2 comprises a steel fiber concrete layer 2.1 and a permeable concrete facing layer 2.2 positioned on the steel fiber concrete layer 2.1, wherein a reinforcing mesh 2.11 is arranged in the steel fiber concrete layer 2.1.
In the utility model, the thickness of the steel fiber concrete layer 2.1 is 5-9 cm, and 7cm is taken as an example in this time. The thickness of the permeable concrete facing layer 2.2 is 0.5-1.5 cm, and this time is taken as an example of 1 cm. The steel fiber concrete layer 2.1 is internally provided with a steel bar net sheet 2.11 so as to improve the stress performance of the well cover. The thickness of the upper part of the well cover is about 1cm, the permeable concrete facing layer 2.2 is paved uniformly with the slow running system, and meanwhile, the metal protection ring 3 is arranged on the outer side surface of the well cover 2 so as to prevent the periphery of the well cover from being damaged due to collision. When the metal protection ring 3 is prefabricated in a factory, the metal protection ring 3 is used as a template for pouring a well cover, the reinforcing steel mesh 2.11 is firstly placed, then steel fiber concrete is poured to the position 1cm below the upper edge of the metal protection ring 3 and is vibrated to be compact, then before the steel fiber concrete is completely solidified, the permeable concrete facing layer 2.2 which is paved uniformly with a slow running system for 1cm is continuously poured, and is vibrated to be compact, so that the steel fiber concrete layer 2.1 and the permeable concrete facing layer 2.2 are combined into a whole and stressed together. In order to facilitate the opening of the well lid, an opening hole 2.3 or an opening pull ring is required to be reserved on the well lid, and this opening hole 2.3 is taken as an example.
When the well lid device is installed on site, after the well lid device is installed and the permeable concrete around the well lid is paved, the well lid device is sprayed with a color coating along with the permeable concrete, and the color of the color permeable concrete is sprayed, so that the color coating is sprayed on the invisible well lid along with the permeable concrete, and the color and the appearance are integrated.
It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present utility model, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the utility model, and are also considered to be within the scope of the utility model.
