Preferably, the water inlet and the water outlet are coaxially arranged.
Preferably, the central axes of the water inlet and the water outlet are parallel to the horizontal plane.
Preferably, the drain opening is spaced from the horizontal ground by a distance greater than the distance of the lowest point of the water inlet and the water outlet from the horizontal ground.
Preferably, the access opening and the drain opening are coaxially arranged.
Preferably, a detachable flange cover is arranged in cooperation with the access opening.
Preferably, the overhaul hole under the flange cover is provided with an anti-falling net in a matched mode.
Preferably, a flange plug is arranged in cooperation with the water outlet.
Preferably, the inner side wall and the outer side wall of the four-way piece are both provided with anti-corrosion coatings.
The utility model provides a multifunctional vertical shaft overhaul structure which comprises a four-way piece, wherein the four-way piece is respectively matched with a horizontal ground, a water diversion pipeline and a drainage pit.
The utility model integrates the functions of the manhole, the inspection well, the ventilation shaft and the water collecting well, and has the beneficial effects that:
(1) The problems of large excavation depth, large occupied area and large construction difficulty of the construction reinforced concrete well are avoided, the installation is simple, the construction is convenient, the occupied area is small, and the construction period is greatly shortened;
(2) The four-way piece overcomes the defects that the conventional manhole equipment is difficult to place and the drainage is difficult because no water collecting well exists during the pipeline drainage, and the pipeline drainage effect is good;
(3) The four-way part is made of the same material as the pipeline, is simple in material taking, and can be used as a ventilation shaft besides a daily overhaul function;
(4) Simple structure saves the cost, makes things convenient for maintainer to operate, and factor of safety is high, long service life tramples the theory of going low carbon environmental protection.
