Problems solved by technology

[0002] Existing underground inspection wells of various types and specifications need to be built manually with cement mortar and clay bricks regardless of the depth. The delay of the project is not conducive to urban traffic and the protection of groundwater resources, and a large number of clay bricks are used, which causes waste of clay resources and does not comply with environmental protection policies

Embodiment Construction

[0022] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings:

[0023] see figure 1 , figure 2 :

[0024] The shape of the inspection well is circular, and the inspection well includes bottom plate 1, well chamber 2, cover plate 3, well shaft 4, well ring 5, and well cover connected in sequence from bottom to top (for the sake of succinct explanation, the accompanying drawings Manhole covers are not shown).

[0025] The well chamber 2 is formed by connecting the upper well chamber 21 and the lower well chamber 22 up and down, and the joints in the vertical direction of the two are tongue-and-groove connections (comprising the lower tongue-and-groove, the upper tongue-and-groove, the lower tongue-and-groove, tongue-and-groove are not shown in the accompanying drawings). The part number of the upper tongue and groove), the upper end surface of the upper well chamber 21 is a plane, and the lower end of the lowe...

Abstract

An assembly type manhole comprises a bottom plate, a manhole chamber, a cover plate, a shaft, a manhole ring and a manhole cover which are sequentially connected from bottom to top and are reinforced concrete prefabricated parts, and at least two inverted U-shaped reserved holes are arranged at the lower end of the manhole chamber. A downwards extending first boss which is concentric with the cover plate and matches with an inner cavity of the manhole chamber is disposed on the lower surface of the cover plate, a step through hole is arranged at a position, which is close to the outer edge, of the cover plate, a first hole and a second hole are vertically communicated with each other to form the step through hole, the size of an opening of the first hole is larger than that of an opening of the second hole, and the central line of the step through hole is parallel to that of the cover plate; the upper end surface of the manhole chamber is a plane; a downwards extending second boss which matches with the first hole is arranged at the lower end of the manhole chamber; the cover plate is placed on the upper end surface of the manhole chamber, and the first boss is inserted into the inner cavity of the manhole chamber; and the second boss is inserted into the first hole. An upwards extending second boss which is concentric with the bottom plate and matches with the inner cavity of the manhole chamber is disposed on the upper surface of the bottom plate and is inserted into the inner cavity of the manhole chamber. By the aid of the assembly type manhole, construction efficiency is high, and clay resources are saved.

Description

technical field [0001] The invention relates to an assembled inspection well used on various underground pipelines. Background technique [0002] Existing underground inspection wells of various types and specifications need to be built manually with cement mortar and clay bricks regardless of the depth. The delay of the project is not conducive to urban traffic and the protection of groundwater resources, and a large number of clay bricks are used, which causes waste of clay resources and does not comply with environmental protection policies. [0003] At present, many local governments stipulate that, except for farmers building low-rise houses on homesteads, it is forbidden to use clay solid bricks as masonry materials in all construction projects and municipal engineering construction. Therefore, in this case, it is imperative to eliminate the traditional clay brick inspection well. Contents of the invention [0004] The technical problem to be solved by the present ...
