Abstract

The prefabricated reinforced concrete combined inspection well is used for water supply, sewage and rainwater discharge, heat supply network, power supply, telecommunication, gas and other pipe networks in urban construction; the prefabricated reinforced concrete combined inspection well consists of a well cover, a closing section, a well shaft and a well seat; the lower port of the closing-up section is made into a step structure with a concave outer diameter, the upper port of the shaft is made into a step structure matched with the step structure with the concave outer diameter of the lower port of the closing-up section, the lower port of the shaft is made into a step structure with a concave outer diameter, the upper port of the well seat is made into a step structure with a concave inner diameter matched with the step structure with the concave outer diameter of the lower port of the shaft, the lower end of the well seat is provided with a bottom plate, and the lower wall is provided with two; installing a shaft on a shaft seat, installing a closing section on the shaft, and installing a well cover on the closing section; the advantages are that: the inspection well is made of segmented reinforced concrete prefabricated parts, so that the field working efficiency of the inspection well is improved, and the construction period is shortened; the bearing capacity is large, and the bearing is easy to damage; not easy to leak and does not pollute the underground water.

Description

The prefabricated reinforced concrete combined inspection shaft

Technical field:

The invention is the manhole of pipe networks such as the feedwater that is used for urban construction, effluent discharge, storm-water drainage, fire-fighting, heat supply network, power supply, telecommunications, coal gas.

Background technology:

At present, the manhole of pipe networks such as the feedwater in the urban construction, effluent discharge, storm-water drainage, fire-fighting, heat supply network, power supply, telecommunications generally adopts brick, and bearing capacity is not enough, destructive loss often appears in work progress, because brick, seepage and polluted underground water often appear in long construction period.

Summary of the invention:

The purpose of the invention provides a kind of prefabricated reinforced concrete combined inspection shaft that shortens the construction period of manhole; The purpose of the invention is achieved through the following technical solutions: the prefabricated reinforced concrete combined inspection shaft is characterized in that being made up of close up section, pit shaft and well seat; The section that closes up lower port is made the recessed ledge structure of external diameter, the ledge structure that the recessed ledge structure of the pit shaft upper port section made and close up lower port external diameter matches, the pit shaft lower port is made the recessed ledge structure of external diameter, well seat upper port is made the recessed ledge structure of internal diameter, the ledge structure recessed with pit shaft lower port external diameter matches, and well seat lower end is shaped on base plate, is shaped on through hole on well seat sidewall, it is big that through hole is made the internal orifice diameter, the through hole that the collar extension diameter is little; Pit shaft is contained on the well seat, and the section that closes up is contained on the pit shaft.

The advantage of the invention: because manhole is adopted segmental structure, and these segmental structures can be prefabricated into reinforced concrete member in advance, can constitute a complete manhole in the manhole job site as long as segmental structure installed in order, improve the site work efficient of manhole, shortened the construction period of manhole; Because adopt precast reinforced concrete structure, bearing capacity is big, and is not fragile; Owing to adopt precast reinforced concrete structure, not easy to leak, not polluted underground water.

Description of drawings:

Fig. 1 is a prefabricated reinforced concrete combined inspection shaft structural representation.

Among the figure: 1, well lid 2, closing in section 3, pit shaft 4, well seat 5, through hole

The specific embodiment:

The prefabricated reinforced concrete combined inspection shaft is characterized in that being made up of close up section, pit shaft and well seat; The section that closes up lower port is made the recessed ledge structure of external diameter, the ledge structure that the recessed ledge structure of the pit shaft upper port section made and close up lower port external diameter matches, the pit shaft lower port is made the recessed ledge structure of external diameter, well seat upper port is made the recessed ledge structure of internal diameter, the ledge structure recessed with pit shaft lower port external diameter matches, and well seat lower end is shaped on base plate, is shaped on through hole on well seat sidewall, it is big that through hole is made the internal orifice diameter, the through hole that the collar extension diameter is little; Pit shaft is contained on the well seat, and the section that closes up is contained on the pit shaft.

Well lid is contained on the section that closes up.

Well lid, close up section, pit shaft and well seat are made circle, can make tetrahedron, can make six shapes, can make octahedral shape, also can make 16 shapes and ellipse.

The through hole of making on well seat sidewall can be shaped on two through holes or three through holes or four through holes and more as required, and it is big that through hole is made the internal orifice diameter, and the through hole that the collar extension diameter is little is convenient to plaster after tube connector is installed.

Advantage: because inspection shaft is adopted segmental structure, and these segmental structures can be in advance pre-Make reinforced concrete member, need only in the inspection shaft job site segmental structure is installed in order Can consist of a complete inspection shaft, improve the work on the spot efficient of inspection shaft, shorten The construction period of inspection shaft; Because adopt precast reinforced concrete structure, bearing capacity is big, show easily Damage; Owing to adopt precast reinforced concrete structure, not easy to leak, not polluted underground water.

Claims

1, prefabricated reinforced concrete combined inspection shaft is characterized in that being made up of close up section, pit shaft and well seat; The section that closes up lower port is made the recessed ledge structure of external diameter, the ledge structure that the recessed ledge structure of the pit shaft upper port section made and close up lower port external diameter matches, the pit shaft lower port is made the recessed ledge structure of external diameter, well seat upper port is made the recessed ledge structure of internal diameter, the ledge structure recessed with pit shaft lower port external diameter matches, and well seat lower end is shaped on base plate, is shaped on through hole on well seat sidewall, it is big that through hole is made the internal orifice diameter, the through hole that the collar extension diameter is little; Pit shaft is contained on the well seat, and the section that closes up is contained on the pit shaft.
