Description
Technical Field
The utility model relates to a permafrost region plumbing field especially relates to a permafrost region overhead structure house centralized blowdown structure.
Background
In the permafrost region, in order to prevent that the heat transmission that house self produced from leading to the underground to the permafrost to melt, ground bearing layer changes, finally produces harm to the house ground, consequently many houses all adopt built on stilts sunshade ventilation structure, and this kind of built on stilts sunshade ventilation structure can form ventilation channel between building and ground, and reduce the temperature protection permafrost layer, has the sunshade effect simultaneously and reduces the heat radiation of solarization to the earth's surface. The house structure is located in a permafrost region, the environment temperature is low, sewage in the sewage discharge pipeline below the bottom plate is easy to freeze, a sewage discharge system is paralyzed, and the life is very inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a blowdown structure is concentrated in permafrost region overhead structure house that sewage is easily frozen and the paralysed problem of the blowdown system that causes is provided for effectively solving under the floor of permafrost region overhead structure house sewage pipes.
In order to solve the problem, a blowdown structure is concentrated in permafrost region overhead structure house, including arranging the overhead structure house on the permafrost layer in, its characterized in that: a centralized sewage drainage system is arranged in an overhead ventilation area between the perennial frozen soil layer and the overhead structure house; the bottom plate of the overhead structure house is arranged above the centralized sewage discharge system, and the heat-insulating layers arranged above the surface layers of the permafrost layers are arranged below and around the central sewage discharge system; PVC protective layers are arranged on two sides of the surface layer of the heat-insulating layer; the centralized sewage discharge system consists of a sewage discharge pipe connected with each overhead structure house sewer pipe and a radiator connected with the indoor heating system of the overhead structure house; the radiator is arranged below the sewage discharge pipe and is arranged above the heat insulation layer; the tail end of the sewage discharge pipe is connected with the septic tank.
And the heat insulation layer is fixed on the columns, the beams and the bottom plate of the overhead structure house through a steel structure.
The heat-insulating layer is made of polyurethane heat-insulating material.
Compared with the prior art, the utility model has the following advantage:
1. the utility model uses the overhead space under the bottom plate of the overhead structure house in the permafrost region to concentrate and discharge the various sewages in the house without influencing the ventilation effect, thereby forming an under-plate centralized sewage discharge system; meanwhile, a radiator is arranged below the sewage discharge pipe and above the heat insulation layer, and the heat dissipation of the radiator prevents the sewage in each sewage discharge pipeline of the centralized sewage discharge system from freezing, so that the problem that the sewage in the sewage discharge pipeline under the floor of the overhead structure house in the permafrost region is easy to freeze and the sewage discharge system is paralyzed is effectively solved.
2. The utility model discloses concentrate the drainage top to be the house bottom plate, below and four sides are equipped with the heat preservation around, and each heat preservation contact surface closely bonds totally inclosed in will concentrating the drainage to reduce the influence of air ambient temperature to concentrating the drainage regional interior temperature and let the temperature stable in the blowdown, and improve the thermal efficiency of radiator.
3. The utility model discloses simple structure, low cost.
