Product Features: Friends of the special rotational molding, interpolating inspection wells, piping inspection wells, municipal pipeline inspection wells, manholes starting Description: Straight inspection wells, three inspection wells, manholes initial inspection wells are used in the construction district (residential areas, public buildings area, plant, etc.) range of plastic drainage pipes buried outside diameter of not more than 800mm, burial depth of not more than 6m, generally located in the drainage Road Interchange, bend, diameter or slope change at the drop Water Department, etc., in order to facilitate periodic inspection Details: straight manholes, three inspection wells, manholes initial inspection wells are used within the construction area (residential areas, public buildings, areas, factories, etc.) range of plastic drainage pipes buried outside diameter of not more than 800mm, burial depth of not more than 6m, generally located at the junction of drains, bend, diameter or slope change at the drop of the water, etc., in order to facilitate regular inspection, cleaning and inspection operations dredge or go down with the plastic one injection molded or brick-like structures wells. One plastic injection wells manholes refers mainly composed Manhole seat one-time injection molding parts. Depending on the number and angles have taken over the initial wells seat, through wells seat, seat 45 degree elbow wells, three wells seat, four blocks and other wells. In order to adapt to a variety of drainage conditions, plastic manholes while supporting a complete set of plastic adjustable joints, the bus connectors, connectors and other integrated multi-wellbore injection molding accessories. To safeguard the smooth and seal the entire drainage system. Plastic Manhole components: patio plastic seat inspection wells from wells, bore, seat covers, and covers, etc., in order to clear through, well-shaped structures inspection, the wells seat check bore wells made of plastic, called plastic manholes. Friends of the special plastic manholes easy to install, light weight, easy to transport and construction, reliable performance, strong bearing capacity, impact resistance, corrosion resistance, aging resistance, easy connection to the plastic pipe, sealing, and effectively prevent water leakage, safety and environmental protection; smooth wall smooth, easy dirt retention, reducing the possibility of clogging, greatly enhanced emission rate; wellbore can be cut on site, adjust, adapt to a variety of mounting depth requirements, reduce into all-weather construction. Greatly improve the construction schedule, construction efficiency is 10 - 20 times more than traditional checking wells. Manhole general design life of 50 years, able to withstand more than 20 tons of vehicle load on the city's main thoroughfares. Friends of the special plastic manholes using advanced production technology, is committed to providing quality products and services to China's booming building materials market, together with the relevant research institutes form the Industrial Technology Innovation Alliance, Institute for building enterprise with an excellent and famous universities a combination of common technology platform for innovation. In product design, materials technology improvements, intelligent detection and other advanced technology to build plastic manholes, leading China into a new era of plastic manholes ease of use, reliability, economy, environmental protection and the! Structural design analysis ① plastic inspection wells in the bottom of the well seat body had stiffened distribution design, structural design principles using beam with vertical ribs, greatly enhancing the well seat ring stiffness and overall force, to achieve uniform bearers. ② seat bottom of the well using the transparent design, the bottom of the well back to fill more seats filled, no gaps, no virtual earth, to reality backfill to ensure uniform settlement. ③ no shear force design - Manhole load transfer directly to the manholes base to prevent the well bore at the base socket fracture under load. ④ multi-model design - to achieve a common variety of sizes to meet the different needs of the construction site. In order to meet the development needs of the company, is now facing the provinces, municipalities and autonomous regions Recruitment quality or municipal distributors, resellers, willing to work together with you to develop this,
