Abstract
A structure for preventing the pollution of an inspection well of a gravity current pipe network comprises a gravity current pipeline, the inspection well, a man hole, a well lid and an inspecting and clearing facility. The utility model is characterized in that a buttress of a gravity current pipeline is arranged on the bottom surface of the inspection well; a connecting flange and an air pressure valve for balancing the air pressure of a pipe network are additionally arranged at the upper part of the gravity current pipeline; and the air pressure valve comprises a pipeline, a lower connecting flange and a top rain shielding cover; the pipeline of the air pressure valve is led out from a penetration hole on the side wall of the inspection well; the top rain shielding cover is higher than the ground surface nearby the inspection well; spunyarn asbestos and cements are used to fill the cavity between the pipeline and the side wall of the inspection well. Compared with the prior inspection well of the gravity current pipe network, the inspection well of the utility model has the following advantages: a traditional opening structure is changed into a relatively enclosed structure, so that a circulating water system isolates from the other environments; and the functions, such as checking, clearing, and safe operation, of the original opening structure are ensured and improved, so that the utility model has greater popularization and application value.
Description
Technical field
The utility model belongs to the technical field of industrial circulate water pipe network Antipollution method and device, is specifically related to a kind of gravity current pipe network manhole anti-pollution structure of industrial circulate water.
Background technology
Industrial circulate water adopts the gravity current pipe network to carry, and prior art will be offered a manhole every certain distance on pipe network.Conveyance conduit in the pipe network disconnects in manhole, is convenient to inspection and clear and coherent, there is no other anti pollution facilities except well lid.This Open architecture not only makes ground rainwater and dirt be easy to just enter in the system, thereby the water in the pipe network is polluted, and the increase subsequent treatment is loaded and caused waste; And following the oozing when carrying poison sewage in can't avoiding managing and contaminated soil and underground water cause public hazards.
By the retrieval on the State Intellectual Property Office website, the inventor does not find the design scheme that how can prevent effectively that the gravity current pipe network from polluting; And become day by day precious and environmental issue is required very strict today at freshwater resources, this problem ought to come into one's own, so we during large-scale and ultra-large type alumina producer, have just considered this problem in design emphatically.
The utility model content
The purpose of this utility model is exactly will seek a kind of gravity current pipe network manhole that can effectively prevent to avoid the design scheme of rainwater and the pollution of other dirt.
Gravity current pipe network manhole anti-pollution structure of the present utility model comprises the clear and coherent facility of gravity current pipeline, manhole, manhole, well lid and inspection, it is characterized in that:
(1) the manhole bottom surface is provided with the buttress of gravity current pipeline;
(2) be provided with the air pressure valve of adpting flange and equilibrium air pressure in addition in the gravity current conduit upper.
Gravity current pipe network manhole anti-pollution structure of the present utility model, the air pressure valve that its balance pipe network air pressure is used is made up of pipeline, bottom adpting flange and top rain cover.Its underpart adpting flange connects with the top adpting flange of gravity current pipeline during installation.
Gravity current pipe network manhole anti-pollution structure of the present utility model, the pipeline of its air pressure valve can be drawn from the perforation of manhole sidewall, and makes its top rain cover exceed near the ground line of manhole.The air pressure valve pipeline tamps material with available spunyarn asbestos and cement between the manhole sidewall cavity as pore and tamps.
Gravity pipe network manhole anti-pollution structure of the present utility model is compared with traditional gravity current pipe network manhole, and its main advantage is: 1, change traditional Open architecture into the relative closure structure, reclaimed water system and other environment are isolated; 2, guarantee and improved traditional inspection that Open architecture had, clear and coherent and the safe handling function.Owing to have above-mentioned advantage, so have bigger application value.
Description of drawings
Fig. 1 is the structure chart of traditional gravity current pipe network manhole; Fig. 2 is gravity current pipe network manhole anti-pollution structure figure of the present utility model, and Fig. 2 A is an elevation; Fig. 2 B is a lateral view.Among above-mentioned each figure, 1 checks clear and coherent equipment, 7 pipeline adpting flanges, 8 air pressure valve flanges, 9 air pressure valve pipelines, 10 air pressure valve rain covers, 11 pores for manhole pit shaft, 2 gravity current pipelines, 3 buttresses, 4 well lids, 5 manholes, 6 tamps material.
The specific embodiment
Below in conjunction with specific embodiment structure of the present utility model is further described and replenishes.
As can be seen from Figure 1, existing its gravity current pipeline 2 of gravity current pipe network manhole disconnects in well.The slope connection of system will be smeared a little more than the bottom surface of the outlet pipe mouth of pipe in the bottom surface of its water inlet pipe mouth of pipe with cement between two mouths of pipe.Pit shaft 1 top there is no other anti pollution facilities except that hiding with well lid 4.The utility model is then different, shown in Fig. 2 A, 2B, at first, has built buttress 3 by laying bricks or stones on the manhole bottom surface, and gravity current pipeline 2 just is arranged on the buttress, and itself seals pipeline.Because pipeline seals, can prevent from effectively to pollute.And, be provided with adpting flange 7 in conduit upper in order to guarantee the air pressure balance of pipeline.The utility model is provided with air pressure valve in addition, and it is made up of flange 8, pipeline 9 and 10 3 parts of rain cover.Wherein air pressure valve flange and upper and lower being connected of gravity current pipeline adpting flange.The air pressure valve pipeline then passes the pore of manhole sidewall and upwards draws, and makes the rain cover on its top exceed ground on every side.Tamping material 11 with pore between the pore of air pressure valve pipeline and manhole sidewall tamps.After gravity current pipeline and air pressure valve installed, installation check cleaning equipment 6 and manhole 5 were installed well lid 4 at last again, and gravity current pipe network manhole anti-pollution structure then of the present utility model is successful installation just.
