The invention discloses a method for preparing an injection-molded inspection well that is easy to enter, and relates to the technical field of plastic products, comprising the following steps: injection molding, mixing raw materials and pouring them into an injection molding machine, using a mold to inject and mold the main body of the inspection well, and cooling to room temperature After use; engrave thread, engrave thread groove on the inner wall of the main body of the inspection well, the pitch of the thread groove is 5-10cm; install the lifting device, weld the spring to the bottom of the lifting platform, and then put the spring base into the bottom of the injection molding inspection well Fixing, the lifting table is installed into the thread groove; adding a shock-absorbing layer; plating, spraying waterproof paint on the outside of the shock-absorbing foam board, and putting it in the warehouse for storage after curing. The preparation method of the easily accessible injection molding inspection well is convenient for operators to enter the interior of the inspection well for construction, can avoid the problem that the injection molding inspection well is easily damaged by external vibrations and impacts of crushed stones, and can increase the waterproofness of the injection molding inspection well.
Description
technical field [0001] The invention relates to the technical field of plastic products, in particular to a method for preparing a conveniently accessible injection molding inspection well. Background technique [0002] The inspection well is used in the construction area (residential area, public building area, factory area, etc.) to buried plastic drainage pipes with an outer diameter of no more than 800mm and a buried depth of no more than 6m. Or the place where the slope changes, the place where the water falls, etc., in order to facilitate regular inspection, cleaning and dredging, or the well-shaped structure made of plastic injection molding or bricks for downhole operation inspection, the plastic integral injection inspection well refers to the main part of the inspection well. The well base part adopts one-time injection molding, the well shaft socket adopts a 360-degree ring-shaped bearing platform, the well body and the bottom of the well base adopt mesh reinforce...
