Description
Technical field
The utility model relates to water supply and drainage field, relates in particular to a kind of manhole for drainage system.
Background technology
Along with the quick increase of China's Economic Synthesis Strength, incident is that the aspect such as safety, environmental protection of living environment is required constantly to improve.
At present the most of large-and-medium size cities of China all complete the improvement project of municipal rainfall and sewage pipes road shunting, and each newly-built, reconstruction building also requires in region rainwater and life, the pipeline of producing dirty waste water to separate design.Rainwater in region generally directly drains into the Storm Sewer Network near river course or near the town road this plot.
Wherein, comparatively popular discharging modes are natural river course formula discharge, and this kind of mode locates to be provided with inspection shaft in turning, the branch of drainage pipe, fall etc., so that check and the work such as dredging, have not only economy but also the advantage such as reasonable.But due to the limitation of traditional inspection shaft 26S Proteasome Structure and Function, this kind of discharging modes remain following problem:
1, the design standard of current China, it is taking long-term water level as foundation that rainwater drainage pipe drains into river course absolute altitude, but sharply rises at flood peak period water level, forms and pours in down a chimney, the harm people's property safety in the time that water level exceeds region site elevation.
In some industrial enterprises because its nature of production has been stored poisonous and harmful substance, leak and very likely enter natural river course polluted source by Storm Sewer Network as unexpected generation, cause environment pollution even endanger near the people's life security.
Summary of the invention
In order to address the above problem, the utility model provides a kind of manhole for drainage system, by increased hand safety-valve in well, can effectively avoid river course water to pour in down a chimney the generation of phenomenon, meanwhile, also can effectively avoid poisonous and harmful substance to leak the potential safety hazard that enters river course.
Above-mentioned a kind of manhole for drainage system, comprise fixation steel plate, securing cover plate and top steel plate, described fixation steel plate arranges along well inside wall, described securing cover plate is covered in the well head place at manhole top, described top steel plate is positioned at the upper surface of securing cover plate central area, and the central area of described securing cover plate and top steel plate is provided with hole; Wherein, described manhole also comprises safety-valve, and described safety-valve is installed fixing by the hole on securing cover plate and top steel plate.
In the said equipment, described manhole is square bar tendon concrete structure.
In the said equipment, described fixation steel plate quantity is 2.
In the said equipment, the length of described securing cover plate is 800mm.
In the said equipment, the length of described top steel plate and the wide 500mm that is.
In the said equipment, described safety-valve is hand valve.
In the said equipment, described manhole is also provided with cat ladder and moving mesh cover plate.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of manhole for drainage system, by increased hand safety-valve newly on the basis of traditional inspection shaft, the mode of recycling artificial regulatory avoids river course water to pour in down a chimney the generation of phenomenon, and then effect avoids the poisonous and harmful substance to leak the potential safety hazard that enters river course, finally reach the object of the potential safety hazard existing in solution prior art.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the top view of manhole in the utility model;
Fig. 2 is the A-A generalized section of manhole in Fig. 1;
Fig. 3 is the B-B generalized section of manhole in Fig. 1.
detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
Fig. 1 is the top view of manhole in the utility model; As shown in Figure 1, the utility model has been recorded a kind of manhole for drainage system, comprises securing cover plate 1, fixation steel plate 2, top steel plate 11 and safety-valve 5; Described fixation steel plate 2 arranges along well inside wall, the fixture using this as safety-valve 5.
Preferably, the manhole in the utility model is also provided with moving mesh cover plate 3, cat ladder 4 and water pipe 6, and the material of this cat ladder 4 is stainless steel, the application life of improving cat ladder 4 with this.
Above-mentioned manhole is square reinforced concrete well, and the quantity of fixation steel plate 2 is 2.
Further, securing cover plate 1 is covered in the well head place at manhole top, top steel plate 11 is arranged to the upper surface of securing cover plate 1 central area simultaneously, and, be provided with hole 12 in securing cover plate 1 and the central area of top steel plate 11, fixing so that above-mentioned safety-valve 5 is installed by this hole 12.
Preferably, the length of above-mentioned securing cover plate 1 is 800mm, and the length of above-mentioned top steel plate 11 and the wide 500mm that is.
Simultaneously, above-mentioned safety-valve 5 is hand valve, can realize in the rainwater design system without changing whole region by this safety-valve 5, also without changing under the prerequisite of form of export of rainwater, the generation that only need close manually this gate in the time there are above-mentioned two situations and just can stop problem; And this province of structure investment, and conveniently implement to there is actual operability, be applicable to each newly-built, transformation project.
In actual use, first will need to drain into according to calculation of parameter such as the catchment area of this region reality, rainfall intensity, charge for remittance times the amount of rainfall in river course, concrete formula is as follows:
Rainfall intensity
[q-design rainfall intensity (L/s100m2), P-design recurrence interval (a), t-rainfall duration (min), A, b, the local rainwater parameter of C, n-]
Amount of rainfall
[Ψ-runoff coefficient, gets 1.0, Fw-catchment area (m2) for qy-design rainwater flow (L/s), qj-design storm intensity (L/shm2)]
Then, according to the discharge structure in these regions of data schema such as site elevation, river course ordinary water level absolute altitude, the starting point piping laying degree of depth, conduit slope, caliber and conduit slope, be, mainly the data such as the radical that enters river course rain pipe, caliber, absolute altitude.Or in transformation project, understand manhole place storm sewer in the utility model absolute altitude, the inspection shaft degree of depth, near place can utilize position, vacant lot.
Finally, according to above-mentioned data, determine the position of manhole in the utility model, and according to the choice of diameter gate valve (not marking in the drawings) of water pipe 6; Wherein, the bore of gate valve (not marking in the drawings) is identical with the caliber of water pipe 6.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
