Abstract
The invention discloses a great-slope gutter drainage device, which comprises a U-shaped gutter and rainwater pipe orifices formed in the bottom of the U-shaped gutter, wherein the rainwater pipe orifices are connected with rainwater buckets which are connected with rainwater pipes. The device is characterized in that the U-shaped gutter is inclined; water baffles are arranged below the rainwater pipe orifices along the transverse direction of the gutter; the rainwater pipe orifices are 50 to 100mm away from the water baffles; the height of each water baffle is smaller than 4/5 of the depth of the gutter; two arc-shaped drain outlets are formed in a joint of each water baffle and the bottom of the gutter. According to the great-slope gutter drainage device, rainwater is uniformly discharged, and is effectively controlled to downwards flow along a slope, and the phenomenon of gutter overflow caused by the fact that the rainwater is collected at the lowest position of the gutter, and cannot be timely discharged is effectively prevented.
Description
Technical field
The present invention relates to a kind of method of building draining, specifically, relate to a kind of heavy grade eaves gutter dewatering installation.
Background technology
Common building eaves gutter mostly is the U-lag horizontal arrangement at present.And building arch, the moulding complexity for being designed to, that the cornice absolute altitude changes, realize functional in organized water drainage, such eaves gutter has just produced larger difficulty, simple U-shaped eaves gutter just is difficult to the drainage effect that reaches satisfied, there is certain deficiency in its practicality, there will be rainwater to concentrate lowest part, cause storm-water drainage not as good as and the phenomenon of eaves gutter overflow appears.Along with the complicated and diversified building of modern style is more and more, can well realize normal roof drainage, avoid forming roof ponding, or stormwater overflow, the roof accident such as leak, guarantee that people's normal life and activity in production are designer, constructor and owner's questions of common interest.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of simple in structure, easy construction, prevent storm-water drainage not as good as and the heavy grade eaves gutter dewatering installation of eaves gutter overflow appears.
The technical solution used in the present invention is:
A kind of heavy grade eaves gutter dewatering installation, the rainwater mouth of pipe that comprises U-shaped eaves gutter and be arranged on U-shaped eaves gutter bottom, the rainwater mouth of pipe is connected with roof drain, and roof drain is connected with rain pipe, described U-shaped eaves gutter is inclined to set, and rainwater mouth of pipe below is along U-shaped eaves gutter horizontally set watertight shutter.
The distance of the described rainwater mouth of pipe and watertight shutter is 50-100mm.
The height of described watertight shutter is less than 4/5ths of the eaves gutter degree of depth.
Described watertight shutter and junction, eaves gutter bottom are provided with two arc sewage draining exits.
The beneficial effect of the relative prior art of the present invention:
Heavy grade eaves gutter dewatering installation of the present invention, realize that rainwater evenly discharges, and effectively controls rainwater dirty with the gradient, effectively prevents that rainwater is pooled to the eaves gutter lowest part, storm-water drainage not as good as and the phenomenon of eaves gutter overflow appears.

The specific embodiment
Referring to drawings and Examples, the present invention will be described in detail:
Accompanying drawing 1 to 4 is known, a kind of heavy grade eaves gutter dewatering installation, comprise U-shaped eaves gutter 1 and the rainwater mouth of pipe 4 that is arranged on U-shaped eaves gutter 1 bottom, the rainwater mouth of pipe 4 is connected with roof drain 2, roof drain 2 is connected with rain pipe 3, described U-shaped eaves gutter 1 is inclined to set, and the rainwater mouth of pipe 4 belows are along U-shaped eaves gutter 1 horizontally set watertight shutter 5; The described rainwater mouth of pipe 4 is 50-100mm with the distance of watertight shutter 5; The height of described watertight shutter 5 is less than 4/5ths of eaves gutter 1 degree of depth; Described watertight shutter 5 is provided with two arc sewage draining exits 6 with eaves gutter 1 junction, bottom.
Heavy grade eaves gutter dewatering installation of the present invention, realize that rainwater evenly discharges, and effectively controls rainwater dirty with the gradient, effectively prevents that rainwater is pooled to the eaves gutter lowest part, storm-water drainage not as good as and the phenomenon of eaves gutter overflow appears.
Determine the quantity of leader according to eaves gutter gradient size, more the rain pipe spacing is less for the eaves gutter gradient.
The amount of rainfall design formulas:
Q=k1 * Fq5/10000 or Q=k1 * Fh5/3600
Q---rain water on roof design discharge, L/s;
F---Roof Design catchment area, m
2; (the roofing catchment area is generally less, generally with m
2calculate.Roofing has certain gradient, and catchment area should be calculated according to horizontal projected area.）
Q5---storm intensity during local rainfall duration 5min, L/(s104 m
2);
H5---hour rainfall thickness during local rainfall duration 5min, mm/h;
K1---the roofing wash with watercolours when design recurrence interval is a year is let out capacity factor.(when roof pitch is less than 2.5%, k1 gets 1.0; When roof pitch is greater than 2.5%, k1 gets 1.5～2.0.）
Maximum vent flow according to roof drain and rain pipe during the amount of rainfall design calculates consideration.
Without situations such as facade requirements, by experience, arrange standpipe according to roof pitch and building, divide and calculate the catchment area of every standpipe, calculate the amount of rainfall Q that every standpipe need be drained.The design amount of rainfall is not more than design maximum vent flow in table 1, determines the rain leader downspout caliber.
Table 1
| Design maximum vent flow (L/s) | 75 | 100 | 125 | 150 | 200 | … |
| Caliber (mm) | 9 | 19? | 29 | 42 | 75 | … |
The watertight shutter high computational
Storm intensity during by rainfall duration 5min is calculated:
4/5H≥h≥300Q’?/F’
H---eaves gutter height,
H---watertight shutter height
Rainwater vent flow in Q ' t---the t time between two watertight shutters
F '---eaves gutter floor space between two watertight shutters
Advantage of the present invention is:
With common horizontal eaves gutter, compare, heavy grade eaves gutter rainwater can be along with under the gradient tilts to gush, if according to conventional eaves gutter draining way, for the lower leader, can cause rainwater too to concentrate and the phenomenon of difficult discharge, it is dirty with the gradient that the present invention can effectively control rainwater, solves the too concentrated problem of rainwater.
Because the region rainfall intensity different is also thereupon different with amount of precipitation, the width of eaves gutter and height will be according to spans, the spacing of leader, and these parameters such as the area of drainage grade and draining and amount of precipitation are determined jointly.With precipitation intensity 220mm/hr, 1 leader is that example is set forth the present invention.
If in eaves gutter, drain slope is 15 degree, the spacing of two leaders is 6m, the roofing width is 15m, the accumulating capability coefficient value is 2, gutter width and for the degree of depth is respectively 500mm and 250mm, and reduction coefficient is 0.8, draw as calculated: the eaves gutter sluicing gradient is 0.268, amount of rainfall Qr is 0.011m3/s, and eaves gutter displacement Qg is 0.957 m3/s, and the leader diameter is selected 90mm.
The quantity setting of watertight shutter is identical with the quantity at leader hole, and every 6m establishes a watertight shutter, and the width of establishing eaves gutter is 500mm, and the width of watertight shutter is equal to the width of eaves gutter.According to 4/5H >=h >=300Q '/F ', the height that calculates watertight shutter is that 4/5 * 250 >=h >=287/1.2m2 is 200mm >=h >=239mm.
When rainwater tilts to flow down along eaves gutter, the rainwater that every baffle plate all will play to block in corresponding partition is to the effect of low direction diffluence, and the rain pipe that makes rainwater directly enter the baffle plate side is discharged eaves gutter, thereby prevented that rainwater from collecting to lower, effectively solved lower rainwater excess enthalpy and concentrated and the low problem of rain pipe discharge rate of eminence.
