Description

plastic manhole

technical field

The utility model belongs to the field of municipal facilities, in particular to a novel plastic inspection well for rainwater and sewage.

Background technique

The inspection wells used for rainwater and sewage in traditional residential areas and municipal facilities are mainly brick wells (built from clay bricks and cement), which are composed of manhole covers, manhole cover seats, well shafts, well chambers and other parts. The wellbore and the well chamber wall are provided with steps for maintenance personnel to go up and down, and the well chamber body is provided with inlet and outlet branch pipe interfaces. Although it has the advantages of simple structure and low cost, it has the following problems. Brick-built wells are mainly built from clay-fired bricks, and the mortar in the gaps is prone to not being compacted; generally, subsidence and subsidence are prone to occur within 1 to 2 years after the well body is built. For sewage inspection wells, brick-built wells Seepage can also pollute groundwater resources. In addition, the construction of brick wells has a large amount of excavation, slow progress, poor drainage capacity, short service life, and poor quality stability. Especially in the joints between plastic pipes for rain and sewage and inspection wells, it is easy to leak, resulting in advanced pipes and backward ones. Inspection wells do not match the contradiction, resulting in more problems.

Traditional brick wells are not recyclable, polluting the environment and wasting resources.

Contents of the invention

The utility model provides a sewage inspection well made of plastic material with long service life.

A plastic inspection well, including a well cover and a well shaft, the bottom of the well shaft is connected with a sedimentation seat or a connecting head; the sedimentation seat is composed of a sedimentation chamber and a joint, the sedimentation chamber is coaxial with the well shaft, and the joint is perpendicular to the well shaft;

The wellbore is composed of an inner liner and an outer shell, and the inner liner and the outer shell are connected by spiral reinforcing ribs.

The side wall of the shaft is connected with the inlet pipe through a saddle joint.

The saddle joint is formed by connecting an inner wall arc plate, an outer wall arc plate and a connecting short pipe. The inner wall arc plate is connected with the connecting short pipe as a whole. Connecting the internal thread of the external thread of the short pipe, the inner wall arc plate is arranged on the inner wall of the wellbore, and the outer wall arc plate is arranged on the outer wall of the wellbore and connected with the connecting short pipe through threads. .

The utility model is environmentally friendly, energy-saving, land-saving, water-saving, recyclable and long in service life. The construction is flexible, fast and efficient, and the construction process is simple, so it has broad prospects for popularization and application.

It can be applied to inspection wells and municipal engineering (mostly large inspection wells with a normal diameter) in building communities (mostly small rainwater and sewage wells, the diameter of which is generally less than 700mm, the buried depth is not greater than 6m, and no operation in wells) 700mm or more) and sewage projects of high-pollution enterprises such as chemical and pharmaceutical industries. In addition, for areas with poor water sources, plastic inspection wells can be used as water collectors to realize the collection and utilization of rainwater resources.
