Sinking type air shaft used for underground space building

Abstract

The invention provides a sinking type air shaft used for an underground space building. The top surface of the sinking type air shaft is a section of the outdoor road surface, and other parts of the outdoor road surface are all sunk into the ground. In the sinking type air shaft used for the underground space building, the position below the top surface is fixedly connected with the top surface to form four side wall plates of an air shaft upper ventilating cavity, roadside drainage ditches covered with water perforated strainers and parallel to the positions above a road are formed in the outer sides of two side wall plates parallel to the road, and air guiding windows communicating with the roadside drainage ditches and the upper ventilating cavity are formed in the upper portions of the two side wall plates; and the lower portion of the upper ventilating cavity finally communicates with an air and smoke discharging draught fan in the underground space building. The sinking type air shaft used for the underground space building has the advantages that the number of times of maintenance is extremely few, and walking is smooth and safe when pedestrians walk on the air shaft, and driving is smooth and safe when vehicles are driven on the air shaft. The sinking type air shaft is applicable to building of sinking type air shafts of various underground buildings which need ventilating such as underground stores and underground warehouses.

Description

technical field [0001] The invention relates to an air shaft for ventilating underground space buildings, especially an air shaft whose top surface is flush with the road surface. Background technique [0002] In order to save construction land, many garages, some shopping malls, warehouses, etc. are built under buildings, green spaces and roads to form underground space buildings. The air quality has reached the corresponding standard. At present, since the air outlets on the upper part of the air shaft are all higher than the ground, some green land and / or other grounds will be occupied for construction. From the point of view of saving construction land, it is obviously regrettable; in addition, the upper part of the wind shaft above the ground also somewhat damages the landscape of office buildings and / or residential quarters. Therefore, in order to overcome these defects, the invention patent with the authorized announcement number CN104563449B and the name "Landscape...

AI Technical Summary

Problems solved by technology

Yet this prior art just exists following three deficiencies because of such structure: one, on the wheel and the dirt on people's shoe bottom surface, must fall into its wind shaft cavity by the grid hole of this cover plate 36 301, a little longer time will inevitably block all the gaps in the graded stone layer 38 at the bottom of the wind shaft cavity 301, and then cause the problem that rainwater cannot be drained along its blind drainage ditch 37—this naturally increases. Increased the number of times for maintenance and removal of dirt, and each time the dirt in the 38 gaps of the graded stone layer is removed, the work intensity is still relatively large

Two, the cover plate 36 can only be covered at the opening of the wind shaft cavity 301 in a manner that can be opened at any time

In this prior art, the hole cover plate 36 with a grid is used as a part of the road surface, and the "occasionally happening" thing has become "occurring all the time". Like this, not only the high-heeled shoes will be damaged, but also the lady's ankle will be sprained.
