  • Detail

Plastic drainage inspection well is a kind of inspection well. The scientific name of plastic drainage inspection well is "plastic inspection well". Commonly known as "plastic inspection well". It is a kind of inspection well. Because it is made of polymer resin by one-time injection molding, it is called plastic drainage inspection well. The well seat part of the plastic inspection well is mostly one-time injection molding, and the connection of changing pipe diameter and angle is achieved by reducing joint, angle changing joint, rubber sealing ring and other accessories. The well cover, shaft and related accessories are developed for the plastic inspection well. The road load acts on the surroundings of the inspection well through the well cover and well seat, avoiding the damage of the road load to the inspection well. Xiaobian has collected relevant information. Now let's take a look at what the plastic drainage manhole is and what functional advantages it has

The road load acts on the surroundings of the inspection well through the well cover and well seat, avoiding the damage of the road load to the inspection well. Xiaobian has collected relevant information. Now let's take a look at what the plastic drainage manhole is and what functional advantages it has

what is a plastic drainage manhole?

plastic manholes are used in building communities (residential areas, public building areas, factory areas, etc.) where the outer diameter of buried plastic drainage pipes is not more than 800mm and the buried depth is not more than 6m. They are generally located at the intersection of drainage pipes, turns, changes in pipe diameter or slope, water drops, etc. in order to facilitate regular inspection A well shaped structure formed by plastic injection molding for cleaning and dredging or inspection of downhole operation

plastic inspection well refers to the one-time injection molding of the main well seat part of the inspection well made of polymer resin materials. According to the number and angle of nozzles, there are starting well seat, straight well seat, 45 degree elbow well seat, three-way well seat, four-way well seat, etc. In order to adapt to various drainage conditions, the plastic inspection well is equipped with reducing joints, confluence joints, shaft multi joints and other plastic integrated injection molding accessories. To ensure the smoothness and tightness of the whole drainage system

the plastic inspection well is made of polymer resin and adopts a combined structure. It is generally composed of inspection well seat, shaft, well cover, etc., which is divided into sewage (waste) water inspection well and rainwater inspection well. The sewage well is generally equipped with a chute to facilitate the smooth discharge of sewage, and the rainwater well (generally equipped with a sedimentation chamber for sediment) is convenient for the later cleaning and maintenance

the connection between the well seat and the buried pipeline should adopt the flexible connection of the rubber sealing ring to adapt to the deformation of the ground seat, etc. the adhesive can only be applied to the socket connection between the well seat made of PVC-U and the diameter of the shaft 315mm and below

selection of plastic manhole components:

1) manhole seats with flow grooves should be used on sewage pipelines

2) the manhole seat on the rainwater pipeline should meet the following requirements:

a. the well seat with a sludge chamber should be used at the road rainwater inlet

b. When it is necessary to set the inspection well of the sludge chamber seat on the rainwater pipeline, it should be set at the inspection well with the outer diameter of the shaft greater than or equal to 500mm

c. Other rainwater inspection wells can adopt well seats with flow grooves

functional advantages

the functional advantages of plastic inspection wells mainly include five points: land saving, energy saving, water saving, material saving and environmental protection

(1) acid and alkali corrosion resistance, aging resistance and long service life

(2) safety and environmental protection, sealing and anti leakage. The material of plastic inspection well is high-density polyethylene plastic, non-toxic and tasteless, which can be recycled after use; Good sealing can prevent rainwater and sewage leakage and leakage, so as to prevent groundwater pollution. It is a chemical environmental protection building material, which conforms to the national policy of environmental protection

(3), uniform settlement, compression resistance. The pipeline is flexibly connected with the well seat, and the clay of the pipeline and the well seat moves together, which solves the problem of uneven settlement caused by the connection between the traditional inspection well and the plastic pipeline, and effectively prevents the ground from collapsing

(4) convenient and fast construction. The split assembly structure is adopted, and the shaft can be cut and adjusted on site to meet the requirements of various installation depths, effectively reduce costs, greatly improve the construction progress, and shorten the construction period, which is more than 10-20 times that of the traditional inspection well; And it can be constructed all day, which is incomparable with brick inspection wells and other cement brick wells

(5) efficient drainage. The inner wall is smooth and smooth, and there is a diversion groove, so the dirt is not easy to stay, reducing the possibility of blockage, and has excellent drainage performance. The rain and sewage discharge rate is 1 ~ 3 times that of the traditional inspection well

(6) light weight, easy to transport and install, reliable performance and strong bearing capacity; With strong adaptability and complete varieties, it can adjust the shaft height, punch holes on the cylinder and adjust the direction to meet all the needs of engineering installation

(7) low comprehensive cost and less maintenance cost, which has more advantages than traditional inspection wells; It can be recycled, which has great social benefits

(8). Good sealing performance and anti leakage. Because of the flexible connection method: flexible and convenient, it can overcome the harsh construction environment of wind dust and sand dust. It can also overcome the difficulty of repeated insertion due to the increase of the road surface

(9) save materials. The plastic inspection well is made of polymer resin instead of red brick cement, which saves topsoil resources; The specifications of the building community are reduced, which greatly saves the land space occupied by the buried inspection well

production process

1. The plastic inspection well produced by injection molding process is formed at one time, with high production efficiency and good quality. The disadvantage is that the mold price is high, and it is limited by the processing performance of raw materials and the power of injection molding machine. It is suitable for the production of plastic inspection wells with a pipe diameter of less than 800mm

2. The advantages of plastic inspection wells produced by winding and secondary molding process are local materials, fast installation, and can produce inspection wells of different specifications. The disadvantage is that the speed is slow, the efficiency is low, and the quality (especially the welding quality) is easy to fluctuate due to human factors

3. The advantage of the inspection well formed by the layer coating process is that it can produce plastic inspection wells of different specifications with local materials. The disadvantage is that the speed is slow, and it is difficult to produce in batch. In addition, it is difficult to guarantee the size and performance of products made by hand. Environmental pollution in production and the inability to recycle raw materials limit its production and use

4. The plastic inspection well produced by rotational molding process has high hardness
