Abstract

A combined type inspection pit component, solves the problems that a brick inspection pit and a concrete placement inspection pit have sewage exosmosis, pollute the environment and the ground water. The combined type inspection pit component comprises a tubular pit wall, a reinforcing and pressurizing ring used as a pit ring is precast at the upper end of the pit wall, and a tube mounting hole matched with a flow channel on a flow channel bottom plate is precast at the lower end of the pit wall. A lengthened pit wall can be precast on the upper part of the pit wall, and the flow channel bottom plate can be precast at the bottom of the pit wall. The inspection pit component can be a reinforced concrete precast component, a glass reinforced plastic precast component or a plastic precast component. The inspection pit changes the traditional brick and concrete placement structure, and precasts the inspection pit to be an integral component. The inspection pit has the advantages of convenient transportation and burial, long service life, and convenient plant production, and in particular, the inspection pit made of glass reinforced plastics has the advantages of anti-corrosion, good water tightness, and light weight. After experiment tests, the performance indexes of the inspection pit built with the component can completely meet operation requirements on drainage works in residential districts. The inspection pit component can also be used as a water meter pit, a valve pit, a fuel gas pit, and a telecommunication pit.

Description

The combined inspection shaft member

Technical field: the utility model relates to the manhole member in the drainage works.

Background technology: at present, according to the needs of national economic development planning and national industrial policies and environmental protection, water resource recycling, housing industrialization, drainage works has in recent years begun to promote edible plastic tubing.But as very important manhole in the drainage system, still adopt brick and concrete pouring, because its physicochemical property instability, in use seepage and damage are more serious, cause sewage to exosmose, contaminated environment and underground water, for this reason, cooperate promoting the use of of plastic pipe, exploitation can just seem extremely important by matching used with it manhole member.

Summary of the invention: the utility model purpose is to solve brick and concrete pouring manhole sewage exosmoses contaminated environment and phreatic problem.

The combined inspection shaft member that the utility model provides, comprise tubular sidewall, this tubular sidewall is integral prefabricated member, in the upper end of this borehole wall or up and down to be shaped in advance with the borehole wall be the reinforcement supercharging ring of one in the end at two ends, the double simultaneously walling crib of doing of supercharging ring is strengthened in the upper end, the lower end of tubular sidewall be shaped in advance with the chute base plate on 2～6 piping erection holes matching of chute, can a prefabricated bell socket that is used for pipe laying of outwards routing up around the installing hole.

Can prefabricated 1～8 lengthening borehole wall above tubular sidewall, strengthen the supercharging ring at the upper end and prefabricated 1～4 of the middle part of this lengthening borehole wall, at the prefabricated one group of shaft orientation reinforcing rib of periphery of the lengthening borehole wall.Can a prefabricated chute base plate in the bottom of tubular sidewall, can prefabricated 2～6 corresponding pipeline chutes in the piping erection hole site with the tubular sidewall lower end on the chute base plate.

Tubular sidewall, the lengthening borehole wall and chute base plate can be precast member for reinforcing bar concrete, also can be the glass fiber reinforced plastic prefabricated units, or the plastics prefabricated units.

The utility model advantage: this manhole has changed the structure of traditional brick and concrete pouring, manhole is prefabricated into integrated member, have transportation and bury convenience, long service life underground, be convenient to the characteristics of plant produced, particularly adopt the manhole of glass fiber reinforced plastic manufacturing also have the intensity height, corrosion-resistant, watertightness good, lightweight characteristics.Through experiment test, the performance indications of the manhole that this member is built can satisfy the instructions for use of residential quarters internal drainage engineering fully.This manhole member can also use as water meter chamber, pipe valve well, combustion gas well, telecommunications well.

The specific embodiment:

Embodiment 1

As shown in Figure 1, this combined inspection shaft member, comprise tubular sidewall 1, this tubular sidewall is integral prefabricated member, in the upper end of this borehole wall or up and down the end at two ends be shaped in advance with the borehole wall be that (this supercharging ring can be gained in strength on the one hand for the reinforcement supercharging ring 2 of one, can prevent borehole wall play displacement up and down on the other hand), the double simultaneously walling crib of doing of supercharging ring is strengthened in the upper end, the lower end of tubular sidewall be shaped in advance with the chute base plate on 2～6 piping erection holes 3 matching of chute, can a prefabricated bell socket that is used for pipe laying 45 of outwards routing up around the piping erection hole.

Degree of depth difference according to manhole, the top of tubular sidewall can prefabricated 1～8 lengthening borehole wall 6 (this example lengthening borehole wall that only draws, roughly the same surplus), supercharging ring 2 is strengthened at upper end and prefabricated 1～4 of middle part at this lengthening borehole wall, the double simultaneously walling crib of doing of supercharging ring is strengthened in the upper end, place (concrete) well lid 7 in the walling crib, the lower end cooperates with the tubular sidewall or the lengthening borehole wall of below.Bottom at tubular sidewall can also be shaped on a chute base plate 8 in advance.These chute base plate prefabricated units also can save, and directly build out a chute base plate with brick and concrete at the bottom of manhole.

Tubular sidewall in the utility model, the lengthening borehole wall and chute base plate can be precast member for reinforcing bar concrete, also can be the glass fiber reinforced plastic prefabricated units, or the plastics prefabricated units.This example is selected the glass fiber reinforced plastic prefabricated units especially for use.Accompanying drawing 2～6 has provided several multi-form installing holes and chute base plate runner schematic diagram, and Fig. 2 is the straight line well, and Fig. 3 is the bend well, and Fig. 4,5 is that a top-cross is converged well, and Fig. 6 is the both sides well that crosses.

Embodiment 2

This example is shaped on a chute base plate 8 in advance in the bottom of tubular sidewall, can prefabricated 2～6 corresponding pipeline chutes in the piping erection hole site with the tubular sidewall lower end on the chute base plate.This chute can be not prefabricated yet, and when construction, according to the position of installing hole, build out chute with brick and concrete on the chute base plate.

When selecting the glass fiber reinforced plastic prefabricated units for use, can be shaped on one group of shaft orientation reinforcing rib in advance in the periphery of the lengthening borehole wall, to improve its intensity, all the other structures are with example one.
