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, must be strong balance Jinzhong ductile covers manufacturers, 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. Ductile cast iron covers are products of one of Jinzhong ductile manhole cover price, then the construction environment ask for? Gu Chang-year foundry to tell you: 1. The covers should have raised the height of not less than 3mm 2. covers, rain grate and bearing surfaces should produce smooth, without cracks and the impact of inspection covers the use of performance. The cold shut, shrinkage and other defects, not welding. 3. Size of seat covers and assembly shall conform to the requirements of Jinzhong ductile covers offer, and to ensure compatibility with the bearing covers. The covers of the contact surface with the bearing support surface is machined to ensure a smooth contact with the bearing covers. 5. covers the carrying capacity of not less than 360KN, allow the residual deformation is 1/300 * carrying capacity D, rain grate is not less than 140KN. Between 6 and seat covers should be made of galvanized chain-linked or other forms of locking device. Grate and Manhole by pin (or other forms) tied, flip angle of not less than its grate 120 °.
