Abstract

The invention discloses a combined pressure-resistant pipeline inspecting well barrel. The combined pressure-resistant pipeline inspecting well barrel comprises N combined pieces and connecting pieces, wherein the outer-circle arc surface of the combined pieces are provided with horizontal reinforcing ribs and longitudinal reinforcing ribs which are intersected mutually; the left sides and the right sides of the combined piece are provided with connecting edges; the longitudinal section of each combined piece consists of a wellhead section, a well cone section and a well seat section; and all the combined pieces are fixedly connected into a barrel-shaped body. The combined pressure-resistant pipeline inspecting well barrel disclosed by the invention has the advantages that due to the combined structure, the processibility for mold-pressing forming of a product is optimized, the requirements for mold-pressing equipment and the structure and volume of a mold are reduced, and the forming efficiency and qualification rate of the product are improved; since a new high-temperature mold-pressing composite forming process of resin glass reinforced plastic is adopted, the ageing resistance, water resistance and corrosion resistance of the product are guaranteed; and since the longitudinal reinforcing ribs, the horizontal reinforcing ribs and two side surface connecting edges are arranged, the compression capability of the product can be improved, the production, carrying and installation of the product are simplified, the comprehensive cost is reduced, and the service life is prolonged.

Description

Technical field:

[0001] The invention relates to a pipeline inspection well bucket, in particular to a pipeline inspection well bucket used for drainage, sewage discharge, and underground wiring pipelines. Background technique:

[0002] There are various underground pipelines used for drainage, sewage, and underground wiring pipelines in the municipal, road administration, and residential quarters. Inspection wells must be installed during the design and construction of underground pipelines for pipeline unobstructed inspections. As well as daily maintenance and repair, it is an indispensable and important building component in underground pipelines. Existing inspection well barrels are all integral cement products or integral injection-molded plastic products. This type of inspection well barrel is large in size, not only difficult to manufacture, low yield, but also very difficult to transport and install, and the compressive strength is also low. High, especially the ins...
