Description

A kind of siphon storm drain energy dissipating manhole

Technical field

The utility model relates to building plumbing system technical field, particularly a kind of siphon storm drain energy dissipating manhole.

Background technology

Large public building is quite large because of rain water on roof catchment area, therefore needs to adopt siphon storm-water system to discharge rain water on roof.The discharge pipe of siphon storm-water system often flow velocity is very large, and sometimes there is a more than storm drain and access in same manhole.Because discharge pipe access direction flows to often vertical with downstream drainage, high speed water flow not and import and just directly impinge upon on the pool wall of opposite, does not import current to other and causes strong disturbance, cause impeded drainage, occur time serious that the manhole cover back of the body is thrown, what current were gushed out rapidly turns over well phenomenon.

Summary of the invention

The purpose of this utility model is to provide a kind of siphon storm drain energy dissipating manhole, with solve be common in siphon storm drain turn over well phenomenon, situation is washed away to the borehole wall.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model discloses a kind of siphon storm drain energy dissipating manhole, include siphon storm drain, energy dissipating concrete well room, deceleration rectification energy dissipating module, deceleration hole, to conflux concrete well room, rain pipe outside the outer rain pipe of upstream chamber and downstream chamber, siphon storm drain is connected with energy dissipating concrete well room, energy dissipating concrete well room is provided with deceleration rectification energy dissipating module, concrete well room of confluxing is connected with energy dissipating concrete well room by deceleration hole, concrete well room of confluxing is incorporated to rainwater main pipe by rain pipe outside the outer rain pipe of upstream chamber and downstream chamber.

Wherein, deceleration rectification energy dissipating module is the latticed porous member of removable pp plastic material.

Wherein, deceleration hole has the deceleration hole pool wall of surface irregularity.

Wherein, concrete well room of confluxing is provided with riffler and weir flow wall.

Wherein, energy dissipating concrete well room, concrete well room of confluxing, deceleration hole, riffler and weir flow wall are reinforced concrete cast-in-situ masonry.

The utility model has following beneficial effect:

1. the utility model is by rationally arranging energy dissipating concrete well room and backflow concrete well room, add deceleration rectification energy dissipating module, deceleration hole pool wall and weir flow wall, effective energy dissipating and rectification can be carried out to the rainwater imported, avoid rainwater and form turbulent flow in access, well room, even occur turning over well phenomenon.

2. wherein have employed deceleration rectification energy dissipating module is latticed loose structure, and adopts pp plastic material, can replace when module deceleration effect of energy dissipation weakens, and reasonable in design is simple, solves traditional energy dissipating well design technology complicated situation.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.

As shown in Figure 1, 2, the utility model discloses a kind of siphon storm drain energy dissipating manhole, include rain pipe 9 outside siphon storm drain 1, energy dissipating concrete well room 2, deceleration rectification energy dissipating module 3, deceleration hole 4, concrete well room 5 of confluxing, riffler 6, weir flow wall 7, the outer rain pipe 8 of upstream chamber and downstream chamber.

Installation process is as follows:

Siphon storm drain 1 is connected with energy dissipating concrete well room 2, and concrete well room 5 of confluxing is connected with energy dissipating concrete well room 2 by deceleration hole 4; Wherein be provided with deceleration rectification energy dissipating module 3 in energy dissipating concrete well room 2, concrete well 5 indoor of confluxing are provided with riffler 6, weir flow wall 7, and deceleration hole 4 has the deceleration hole pool wall of surface irregularity; The concrete well 5 that confluxes is incorporated to rainwater main pipe by rain pipe 9 outside the outer rain pipe 8 of upstream chamber and downstream chamber.

Operating principle is as follows:

During use, rainwater goes out stream rapidly via siphon storm drain 1, imports in energy dissipating concrete well room 2, forms the kinetic energy that a large amount of little eddy current clears up current, reach the effect of deceleration rectification when the deceleration rectification energy dissipating module 3 of latticed loose structure.Current to be confluxed concrete well room 5 through secondary speed-reducing by deceleration hole 4 after energy-dissipating and rectifying flow is slowed down in energy dissipating concrete well room 2.Slow current flow into riffler 6, because current are precipitated at this by the of short duration obstruct silt of weir flow wall 7, after smoothly pass outdoor rain water pipe through weir flow wall 7 and import rainwater main pipe.Process high speed current carry out steadily importing in main main drain after energy-dissipating and rectifying flow, avoid overflow that common siphon rainwater causes and to throw the situation of well lid, avoid washing away the borehole wall simultaneously, ensure that the normal operation of energy dissipating manhole.

The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
