Gu Chang share with you in foundry cast iron covers installation considerations when: 1, in order to enhance Manhole compressive strength, increase Manhole located in the bottom of the area, the installation Manhole, Manhole well inner diameter no larger than the inside diameter. 2, the structure of the body sets wells must be brick structure, the balance must be strong, after the formation of the structure of the force, and the grate before installation Manhole seat. 3. When installing grate seat, seat underside grate not vacant. 4. Place the grate Manhole and seat, should be placed at the bottom of the concrete Manhole and grate seat is not solidified in place, and forced vibration compaction or percussion Manhole, Manhole so closely integrated with the concrete to increase Manhole and grate base station and well body contact area. 5, load after product installation shall not exceed the carrying capacity of the product prescribed. Gu Chang-year foundry Address: Taigu County, State Road 108 towns Hu Dong village crossing. Gu Chang-year construction process foundry ductile iron manhole cover: First check the wells, leading to the underground facilities, such as water supply, drainage, telecommunications, electricity, gas, heat, fire hydrants, valves, sanitation and other entrances. Manhole covers, inspection covers part of the closure, the bearings and covers components. Bearings, inspection covers the fixed part of the examination of the wellhead. Magnesite covers for placement. Covers, inspection covers are not fixed part. Its function is to check the wellhead closed, when the need to be able to open. Then, the embedded depth Which Jinzhong ductile covers, bearing bearing surface to the top surface of the seat height. Jinzhong ductile fracture width covers the gap between the seat and covers. Seat covers bearing surface Jinzhong ductile manufacturers, bearing covers the seat plane. Contact surface covers, seat covers bearing surface in contact with the plane. Finally Jinzhong ductile covers quote Jingkuan inspection covers, bearing the orifice diameter of the largest inscribed circle. Test load when checking composite covers testing requirements applied load carrying capacity. Gu Chang-year foundry mainly produces ductile iron manhole covers, welcome to order!
