I . Introduction, Structure and Features of Plastic Inspection Chamber
1. Introduction to Plastic Inspection Chamber
(1) Plastic inspection chamber for drainage: Featured by a modular structure, the plastic inspection chamber for drainage is usually composed of a chamber body, a riser, accessories and a chamber cover. It is used for connection, dredging and maintenance of buried drain pipes.
(2) Chamber body: It refers to the part at the bottom of the inspection chamber with an interface connected with the drain pipe.
(3) Riser: The ascending passage part that connects to the chamber body at the bottom.
(4) Pipe connection socket: It refers to the component of the inspection chamber that is used for collecting and discharging rainwater and sewage, and for connecting with the drain pipe.
(5) Silt settling pit: It refers to the hopper-shaped chamber that is set up at the bottom of the inspection chamber for collecting impurities from the pipe.
(6) Launder: It is the semicircular sink connected to the upstream and downstream pipes at the bottom of the inspection chamber.It serves to guide the water flow and avoid eddy currents caused by cross-sectional changes in water flow, which could maintain a steady flow state and preventsludgeretention.
(7) Inspection ladder: It is the component that is used in the inspection chamber to allow installation and inspection personnel to climb up and down.
(8) Protective cover frame (bearing ring): The cover frame is installed on the concrete foundation around the riser to prevent the vehicle load from directly acting on the riser of the inspection chamber.
2. Structure and Features of Plastic Inspection Chamber
(1) The plastic inspection chamber is mainly composed of a chamber cover, riser, chamber body and accessories.
(2) The plastic inspection chamber is light in weight, and easy to install and transport.
(3)Processed by one-step injection molding,the plastic inspection chamber offers strong bearing capacity,excellent impact resistance, and smooth inner walls that prevent the retention of dirt and reduce the possibility of blockage, significantly improving the drainage efficiency.
(4) It is characterized by good corrosion resistance,excellent aging resistance and a long service life (the service life of the buried plastic inspection chamber is more than 5 times that of the brick inspection chamber).
(5) It canbeeasily connected with thepipe through theflexible connectionof thepipe and the chamber bodyto ensure uniform settlement, which effectively solves the uneven settlement caused by the connectionbetween the traditional brick inspection chamber and the pipe.With excellent airtightness, plastic inspection chambers effectively prevent sewage leakage,achieving safe and environmentally friendly effect.
(6) The riser can be cut, opened and adjusted on site to meet various installation depth requirements.
(7) Construction can be carried out 24h a day, which improves the construction progress and efectively reduces costs.The construction speed is over 10 to 20 times faster than that of traditional inspection chambers.
