Background technique
In the development process in city, often need to be laid with cable under pavement.However, for the road of part, when
It, can only be under car lane or greenbelt using deep embeded type electricity when being occupied below original pavement by gutter or other cables
Cable ditch is laid with cable, since deep embeded type cable duct is stuffy, has gas or toxic gas, therefore often needs to arrange ventilation knot
Structure.But according to the aeration structure of tunnel type, then need to arrange power supply, ventilation equipment etc., there are construction and maintenance cost are higher
The problem of.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of deep embeded type cable duct aeration structure, have structure simple, leads to
The advantages that wind is practical, low in cost, with overcome the deficiencies in the prior art.
The technical scheme is that a kind of deep embeded type cable duct aeration structure, including deep embeded type cable duct, along deep embeded type
The length direction of cable duct is equipped at intervals at least more than one pair of ventilation duct, and the lower end of ventilation duct is arranged in deep embeded type cable duct
Interior, ground is extended in upper end, and each pair of ventilation duct includes the first ventilation duct and the second ventilation duct, wherein the first ventilation duct bottom nozzle exists
Position in deep embeded type cable duct is low compared with the position of the second ventilation duct bottom nozzle, and the position of the first ventilation duct top ports is logical compared with second
The position of air hose top ports is low.When ventilation duct cannot directly elevate above the soil, can reveal from greenbelt again after subsurface bending
Ground out.
First ventilation duct top has the first bending section, and the second ventilation duct top has the second bending section, and first is curved
Pars convoluta and the second bending section open end are towards different directions.
The opening of first bending section and the open end of the second bending section are respectively facing deep embeded type cable duct length direction
Both ends.
The open end of first bending section and the second bending section is provided with protective net.
First ventilation duct and the second ventilation duct are arranged respectively close to the two sides of deep embeded type cable duct.
The ventilation duct is threaded through on the upper wall surface of deep embeded type cable duct by water string.
The beneficial effects of the present invention are: each pair of ventilation duct utilizes draught head in the present invention, make gas from the first ventilation duct
End enters, and drives the upper end outflow through the second ventilation duct after deep embeded type cable duct inner air flow, efficiently solves deep embeded type electricity
Cable ditch internal cause gas does not circulate gas, the toxic gas of generation, improves the safety of deep embeded type cable duct.With prior art phase
Have structure simple than, this aeration structure, divulge information practical, it is low in cost the features such as.
Detailed description of the invention
Fig. 1 is that deep embeded type cable duct snorkel arranges profilograph；
Fig. 2 is deep embeded type cable duct snorkel floor plan；
Description of symbols: 1 deep embeded type cable duct, 2 first ventilation ducts, 3 second ventilation ducts, 4 first bending sections, 5 second bendings
Portion, 6 water strings, 7 ground.
Specific embodiment
With reference to the accompanying drawing and invention is described further in specific embodiment:
With reference to Fig. 1 and Fig. 2, a kind of deep embeded type cable duct aeration structure of the present embodiment, including deep embeded type cable duct 1 and ventilation duct,
At least more than one pair of ventilation duct is installed along the length direction interval of deep embeded type cable duct 1, ventilation duct is worn by water string 6
It is located on the upper wall surface of deep embeded type cable duct 1, the water on ground 7 is avoided to leak into deep embeded type cable duct 1, the lower end of ventilation duct
It is arranged in deep embeded type cable duct 1, ground 7 is extended in upper end, and ground 7 herein is the isolation greenbelt among road.If electric
Cable ditch is located under car lane, then ventilation duct need to elevate above the soil 7 from greenbelt after bending twice.
Each pair of ventilation duct includes the first ventilation duct 2 and the second ventilation duct 3, wherein 2 bottom nozzle of the first ventilation duct is in deep embeded type
Position in cable duct 1 is low compared with the position of 3 bottom nozzle of the second ventilation duct, and the position of 2 top ports of the first ventilation duct is compared with the second ventilation
The position of 3 top ports of pipe is low, and the outlet of two ventilation ducts is respectively facing opposite direction.Since the first ventilation duct 2 and second is logical
There are differences in height for air hose 3, and earth's surface is not also identical in the air pressure of different height, and especially lower local air pressure is bigger, in this way
Gas can be flowed into from the top ports of the first ventilation duct 2, into deep embeded type cable duct 1 in rear-guard ventilate, then it is logical through second
The bottom nozzle of air hose 3 flows out, and realizes ventilation.
It is preferred that 2 top of the first ventilation duct has the first bending section 4,3 top of the second ventilation duct has the second bending section
5, the first bending section 4 from 5 open end of the second bending section towards different directions, in this way when wind from different directions come when, windward side
For positive pressure, and leeward is negative pressure, and air is flowed into from the ventilation duct of windward side at this time, and the ventilation duct from leeward or other faces
Ventilation is realized in outflow.
Advantageously, it is possible, that the opening of the first bending section 4 and the open end of the second bending section 5 are respectively facing deep embeded type cable
The both ends of 1 length direction of ditch promote gas using the wind that running car drives due to often there is wagon flow process on road
It flows into from the opening of a bending section, is flowed out from the opening of another bending section.Preferably, the first ventilation duct 2 and the second ventilation
Pipe 3 is arranged respectively close to the two sides of deep embeded type cable duct 1, to realize that deep embeded type trench is taken a breath to the greatest extent.
Preferably, the open end of the first bending section 4 and the second bending section 5 is provided with protective net, in one example, prevents
Protective net is 20 mesh stainless steel protective nets.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
