Problems solved by technology

Although the rotomolded inspection well has many advantages, it has been proved to be unsatisfactory. For example, due to its consistent structural size specifications, it cannot be adjusted on site, it is difficult to meet the installation requirements, and it cannot be adjusted arbitrarily according to the difference in terrain, resulting in Affect its use function, followed by the integral structure brings inconvenience in packaging, transportation, construction and installation

Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below in conjunction with the above-mentioned drawings.

[0021] Such as Figure 1~6 As shown in the figure: 1, manhole cover, 11, observation hole, 12, reinforcing rib, 2, well body, 21, inverted "U" type opening, 3, well seat, 31, reinforcing rib, 32, shoulder, 4. Well arm, 5. Sealing ring.

[0022] An inspection well, such as Figure 1~2 As shown, it is composed of split manhole cover 1, well body 2, well seat 3 and well arm 4, all of which are made of plastic, and are formed at one time by injection molding or rotational molding, and are welded or press-fitted or welded and press-fitted with each other. Fit and seal to form a thin-walled hollow cylinder in the shape of "⊥".

[0023] manhole cover 1 such as image 3 As shown, it is a two-way type, the top surface is provided with an off-center observation hole 11, and the surface is provided with criss-cross reinforcement ribs 12, and the well c...

Abstract

The invention discloses an inspection shaft, which relates to an underground pipeline member for rainwater and sewage drainage and consists of a cover, a body, a base and an arm which are in sealing connection with each other in a manner of fusing or press-fit or the combination of fusing and press-fit. The splitting-type member is simple and convenient in manufacturing and is formed by assembled connection on the spot, adjustable installation connection can be realized based on the difference of onsite landform, the adjustment flexibility ensures the implementation of using functions, the splitting-type member is convenient for packaging, transportation, construction and installation, the standardized construction efficiency is high, and similarly, the inspection shaft can reach excellent anti-seepage performance, long service life and good safety since sealing connection is adopted totally.

Description

technical field [0001] The invention relates to a component in an underground pipeline facility for discharging rainwater and sewage, in particular to an inspection well. Background technique [0002] As we all know, the inspection well is a component of drainage and sewage pipelines. It is a necessary facility for regular inspection and dredging of pipelines and to prevent pipeline blockage. The pipelines buried under the ground in cities are intricate. In the entire pipeline, a certain distance must be required. Set up many manholes. Traditional inspection wells are built with bricks on site, there is no uniform standard, the construction efficiency is very low, the connection with the pipeline is poor, and it is easy to leak. The patent No. 200920122773.1 of the applicant's previous application is "rotational molding inspection well". The technical solution disclosed is an inspection well formed by the rotational molding process as a whole, which realizes standardized pr...
