Embodiment 1

[0045] Embodiment one: if figure 1 As shown, a municipal inspection well includes a well cover 1 and a well body 2 formed by bricks. The bottom of the well body 2 is provided with a vertical passage section 3 and a sewage pipe inspection section 4 and a rainwater pipe inspection section 5 respectively located at the bottom and middle of the vertical passage section 3. The diameters of the sewage pipe inspection section 4 and the rainwater pipe inspection section 5 are larger than the vertical The diameter of the straight channel section 3. People's ladder 6 is installed on the inwall of vertical passage section 3 to facilitate people to climb up and down from vertical passage section 3. Since the sewage pipe inspection section 4 and the rainwater pipe inspection section 5 are respectively located at the bottom and middle of the vertical channel section 3, and the two are not connected, there is no need to set an additional cover plate to separate the sewage pipe inspection se...

Embodiment 2

[0051] Embodiment 2: A construction method of a municipal inspection well, comprising:

[0052] Step a, foundation pit excavation;

[0053] Excavate the foundation pit with a slope of 68 degrees, and the diameter of the bottom surface of the foundation pit is larger than the diameter of the inspection section 4 of the sewage pipe; after that, the bottom surface of the foundation pit is compacted.

[0054] Step b, placing the sewage section module;

[0055] The bottom of the foundation pit is placed into the sewage section module.

[0056] Step c, bricking to form the vertical channel section 3 on the lower floor;

[0057] The upper opening of the sewage section module is brick-built to form the lower vertical channel section 3, and the masonry is laid horizontally in separate skins, and the upper and lower joints are staggered, and the inside and outside are built. The daily height of the masonry shall not exceed 1.2m. When the masonry process is temporarily interrupted for...

Abstract

The invention discloses a municipal inspection well and a construction method thereof. The municipal inspection well comprises a well cover and a well body. The well body comprises a vertical channelsection, a sewage pipe inspection section and a rainwater pipe inspection section, wherein the sewage pipe inspection section and the rainwater pipe inspection section are located at the bottom of thevertical channel section and located in the middle of the vertical channel section respectively; a ladder is arranged on the inner wall of the vertical channel section. The sewage pipe inspection section and the rainwater pipe inspection section are arranged at the bottom of the vertical channel section and arranged in the middle of the vertical channel section respectively, the certain distanceexists between the sewage pipe inspection section and the rainwater pipe inspection section, and the sewage pipe inspection section and the rainwater pipe inspection section are not in the direct connection state; as the certain distance exists between the sewage pipe inspection section and the rainwater pipe inspection section, a movable interlayer is not required to be arranged, and is not required to be opened in the rainwater pipe inspection section.

Description

technical field [0001] The invention relates to the field of municipal pipeline construction, in particular to a municipal inspection well and a construction method thereof. Background technique [0002] Separate management of rainwater and sewage will not cause rainwater and sewage to mix, and rainwater can be used or discharged into rivers after preliminary purification. However, the sewage must be treated by a sewage purification plant before it can be discharged. [0003] The invention patent with authorized notification number CN101629430B discloses a rainwater and sewage composite double-layer inspection well for drainage system. The invention divides the rainwater and sewage pipes into upper and lower layers by setting hinged movable interlayers. But there is following problem in this invention, when overhauling the sewage pipe channel of lower floor, the movable interlayer must be opened in the narrow space of rainwater pipe inspection section before entering the l...
