Problems solved by technology

On the side of the road, the problem of deformation and damage of plastic valve wells is also more prominent due to external forces such as vehicle rolling.
Therefore, the application of plastic valve wells still has relatively large technical obstacles

Abstract

The invention relates to a high-strength plastic valve well, and aims at providing a high-strength plastic valve well which is convenient to use. The valve well comprises a well body and a well cover component, wherein the well cover component comprises an inner cover and an outer cover; the inner cover is directly connected with the well body; a stepped recess is arranged on the outer surface of the inner cover; and a card is arranged on a step table of the stepped recess, so as to form a handle which is convenient to uncover. The high-strength plastic valve well disclosed by the invention is durable in use, corrosion-resistant, low in cost, simple and reasonable in structure design, high in strength, and convenient to use due to a specially designed handle structure; materials are saved; damages in transportation and installation can be avoided; water leakage is prevented; and the modified sheet mold plastic material is high in strength, simple in formula and convenient to process.

Description

technical field [0001] The invention relates to water supply and drainage facilities, in particular to a valve well made of plastic and used in tap water supply and other similar occasions. Background technique [0002] The valve well is a valve for underground pipelines and underground pipelines (such as tap water, oil, natural gas pipelines, etc.) In order to facilitate the opening and closing of some pipeline network operations or maintenance operations, a pit (or well) similar to a small room is set. Arrange valves and other installations in this pit, which is convenient for regular inspection, cleaning and dredging of pipelines, and prevents the hub of pipeline blockage. This pit is called the valve well. [0003] The traditional valve well is a brick structure, the construction speed is slow, the strength is low, and it is easy to be damaged; it is gradually being replaced by the plastic valve well. The plastic valve well is made of polymer synthetic resin, usually u...
