Proper installation of plastic manhole With the accelerating process of urban construction, and constantly improve the infrastructure, we are also increasing the requirements for facilities. Today, everyone's improved living standards of safety awareness is constantly improving. Therefore, the correct emphasis on construction safety is everyone's problem, and today we come to talk about plastic manholes how construction is safe and correct? Construction inspection wells are generally divided into: Wells and foundation, to take over the installation, borehole installation, backfilling, covers installation, closed water test these six steps. 1, Wells and foundation pit and trench excavation simultaneously, the two should be on the same axis. 2, to take over the installation of the seat and the pipeline should be divided into wells, wells seat fittings and pipes, wells seat and imported pipe, exhaust pipe for the connection is completed in three directions. 3, wellbore installation In this section we should first calculate the length of the wellbore (bottom bearing wells seat height designed to connect the wellbore to the wellbore minus ground clearance for the top to the ground), inserted into the well borehole second seat should remain vertical. 4, backfill this stage should be a drain line (including pipes and manholes) conducted after acceptance, and at the same time with the pipe trench backfill. 5, the front covers installation is measured accurately wellbore length, cut more than part of the wellbore; shall determine the nature of the transmission medium installation, sewage and water wells, etc. can not be confused; in a protective cover and stand sewage manhole should be catchy wellbore install the inner cover. 6, six closed water test should be carried out in accordance with the existing plastic drainage pipes buried Technical specification. Although the manholes of different materials, the installation method and form slightly different, but the overall structure is the same step. Zhengzhou City-source Plastic Co., Ltd.
