Abstract
A gravity and siphoning combined rainwater drainage system for a high-rise building comprises a gravity rainwater drainage system and a siphoning rainwater drainage system. The gravity rainwater drainage system comprises a gravity rainwater hopper which is arranged on the roof and led to the position above the roof of a podium floor through a gravity pipeline. The siphoning rainwater drainage system comprises a siphoning rainwater hopper which is arranged on the roof of the podium floor and led to an outdoor energy dissipation well through a siphoning pipeline. According to the gravity and siphoning combined rainwater drainage system, the advantages of the two rainwater drainage methods are combined, the gravity rainwater drainage method is adopted for a tower in the high-rise building, the siphoning rainwater drainage method is adopted for the podium floor, the advantages of the two rainwater drainage methods are brought into full play, the two rainwater drainage methods work independently and are also combined together, the rainwater drainage efficiency is effectively improved, and pipes are saved.
Description
Technical field
The utility model relates to highrise building drainage system, especially combines gravity drainage system against rain and siphon drainage system against rain.
Background technology
For building, generally can adopt gravity drainage system against rain or siphon drainage system against rain.Siphon type rainwater discharging system effectively intercepts air by special roof drain and enters, and by total system pressure balance, calculates, and has greatly reduced the air capacity of carrying secretly when rainwater enters drainage system, finally reaches the effect of gas-water separation, forms full-section pipe-flow in pipe.Tradition gravity storm-water system is to utilize the Action of Gravity Field of rainwater own to be discharged through drainage system gravity flow by rain water on roof bucket, current entrapped air enters whole storm-water system, air accounts for pipeline 30-70% space, and draining hanging pipe must possess certain slope.Gravity drainage system against rain and siphon drainage system against rain respectively have superiority, and for highrise building, use any drainage system against rain all can have defect, and drainage efficiency is not high, and resource does not reach maximum utilization.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of highrise building gravity and siphon associating drainage system against rain, in highrise building, high building adopts gravity drainage, at annex, adopt siphon drainage, utilized advantage separately, formed the system of oneself, saved tubing, the drainage system of raising the efficiency again.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of highrise building gravity and siphon associating drainage system against rain, comprise gravity drainage system and siphon drainge system, described gravity drainage system comprises the gravity roof drain that is arranged on roof, and described gravity roof drain is by the sensible annex roofing of gravity pipe line top; Described siphon drainge system bag is arranged on the siphon rainwater head of annex roofing, and described siphon rainwater head is by the sensible outdoor energy dissipating well of siphon piping.Gravity drainage system relies on the gravity of rainwater to prolong the non-flowing full draining of pipeline, have simple in structure, the advantage that draining is stable; Siphon drainge system utilizes the siphon flowing full draining in pipeline originally of water, has the advantage that displacement is large.The utility model is in conjunction with the advantage of these two kinds of drainage patterns, and in highrise building, high building adopts gravity drainage, at annex, adopts siphon drainage, has given full play to advantage separately, forms separately system, and associating mutually, effectively improves drainage efficiency again, and saves tubing.
As improvement, described roof is provided with two gravity roof drains, and each gravity roof drain is all by the sensible annex roofing of a gravity pipe line top.
As improvement, described gravity roof drain is 87 type roof drains.
As improvement, described gravity pipe is DN200 steel pipe.
As improvement, described gravity pipe line outlet is apart from annex roofing 10cm.
As improvement, described annex roofing is provided with two siphon rainwater heads, and two siphon rainwater heads converge at a siphon piping.
As improvement, described siphon piping is DN150 steel pipe.
As improvement, described siphon rainwater head comprises chassis, waterproof platen, kuppe, air register.Siphon rainwater head chassis, waterproof platen, kuppe have the characteristics such as anticorrosive, anti-extrusion.Siphon rainwater head has extremely strong anti-eddy current function, can well prevent that air from bringing whole system into by the current of roof drain entrance, and when water level is elevated to a certain degree before bucket, forms water seal and intercept air completely and enter, and make rainwater flood reposefully earial drainage to enter gutter.Hydrocone type roof drain has reduced the depth of accumulated water of gutter to greatest extent, makes the rainwater load that roofing bears be down to minimum, has improved the metered flow of roof drain simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model piping diagram.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, drainage system against rain is combined in a kind of highrise building gravity and siphon, comprises gravity drainage system and annex 7 siphon drainge systems of high building 6.Described gravity drainage system comprises two 87 type roof drains 1 that are arranged on roof 61, and two described 87 type rainwater 1 buckets are respectively by the sensible annex roofing of DN200 steel pipe 2 71 tops, and 2 outlets of DN200 steel pipe are 10cm apart from the high H of annex roofing 71.Described siphon drainge system bag is arranged on two siphon rainwater heads 3 of annex roofing 71, and two described siphon rainwater heads 3 converge in a DN150 steel pipe 4, and by the sensible outdoor energy dissipating well 5 of DN150 steel pipe 4.Described siphon rainwater head 3 comprises chassis, waterproof platen, kuppe, air register.Siphon rainwater head 3 chassis, waterproof platen, kuppe have the characteristics such as anticorrosive, anti-extrusion.Siphon rainwater head 3 has extremely strong anti-eddy current function, can well prevent that air from bringing whole system into by the current of roof drain entrance, and when water level is elevated to a certain degree before bucket, forms water seal and intercept air completely and enter, and make rainwater flood reposefully earial drainage to enter gutter.Hydrocone type roof drain has reduced the depth of accumulated water of gutter to greatest extent, makes the rainwater load that roofing bears be down to minimum, has improved the metered flow of roof drain simultaneously.
Gravity drainage system against rain relies on the gravity of rainwater to prolong the non-flowing full draining of pipeline, have simple in structure, the advantage that draining is stable; Siphon drainage system against rain utilizes the siphon flowing full draining in pipeline originally of water, has the advantage that displacement is large.The utility model is in conjunction with the advantage of these two kinds of drainage patterns, and in highrise building, high building adopts gravity drainage, at annex, adopts siphon drainage, has given full play to advantage separately, forms separately system, and associating mutually, effectively improves drainage efficiency again, and saves tubing.
