Abstract
The utility model discloses a drainage manhole having the advantages of high strength, rapid installation, good impermeability, easy check and maintenance by man. The drainage manhole consists of a round walling cover(1), a walling cover seat(2), a regulating ring(5), a walling bucket(3) and a walling room(4). The utility model is characterized in that: the regulating ring(5), the walling bucket(3) and the walling room(4) adopt a reinforced steel bar concrete one-time forming structure; the upper part of the walling bucket(5) takes the shape of tapering mouth and the inside wall is provided with a U-shaped climbing ladder(6), the walling bucket(3) and the walling room(4) are connected though a gliding rubber sealing ring(8), the connectors of the walling room(2) and a drainage pipe(7) adopt an inserting rubber sealing ring(9) to seal. The utility model has the advantages of long service life, fast installation, effective preventing of leakage and improving the capacity of anti-base-sinking.
Description
Technical field
The utility model relates to a kind of urban construction drainage pipeline project drainage inspection well.
Background technology
Existing urban road, highway, biotope still generally adopt common brick, cement mortar to be built into drainage inspection well, and the interface slit of well chamber and gutter also is a filled with mortar, its shortcoming is that construction technology falls behind, labour intensity is big, speed of application is slow, well body fastness is poor, in piping erection finishes the backfilling of earthwork compacting process, and the phenomenon that the breakage of well body often occurs, tilts even collapse; In addition, because the differential settlement of concrete pipe base, usually cause interface or well body slit and percolating water phenomenon takes place.
Summary of the invention
The purpose of this utility model is to propose fast, impervious good, the drainage inspection well of being convenient to hand inspection and maintenance of a kind of intensity height, installation rate at deficiency of the prior art.
The manhole that the utility model proposes is made up of round manhole cover, manhole cover base, adjustment circle, pit shaft and well chamber, and round manhole cover and manhole cover base adopt the ductile iron casting to form, and it is characterized in that adjusting circle, pit shaft and well chamber and adopts steel bar concrete one-shot forming structure; Upper wellbore closing in flare, inner wall belt U-shaped cat ladder; Pit shaft can be according to the required arbitrary height that is made in building site, and adjusts the well head height by adjusting circle; Pit shaft is connected by slip rubber seal tongue and groove with the well chamber; The interface of well chamber and sewer pipe adopts the sealing of fitting type rubber sealing ring.
Because the utility model adopts the pit shaft and the well chamber of steel bar concrete one-shot forming structure, thereby makes the well body sturdy and durable, but and Fast Installation; Employing slip rubber seal and fitting type rubber sealing ring can prevent the generation of seepage phenomenon, and anti-uneven settlement of foundation ability improves; Shaft in wall U-shaped cat ladder is the important component that is provided with when the pit shaft moulding, and it is different from the rear installed cat ladder of prefabricated well, and is stable and do not come off, more safety and being suitable for.
