Description
Technical Field
The invention relates to the technical field of building drainage system sanitation and safety detection, in particular to a movable building drainage system sanitation and safety detection system and a building drainage system sanitation and safety detection method using the same.
Background
The drainage system is a channel connecting the outdoor sewage drainage pipe and the indoor environment, and the drainage system causes the hidden pollution of the indoor environment to be ignored all the time. In the process of city rapid development, in order to save land, the proportion of high-rise residences is higher and higher, and the phenomenon that the drainage system returns odor is more and more common because of high-density resident population and the pressure of the drainage system in the building is greatly increased. Most of the gaseous pollutants contained in the odor belong to 'three-cause' pollutants, and the contained non-gaseous pollutants can threaten the physical health of residents. Therefore, the sanitary safety performance of the drainage system, namely the performance of ensuring that the indoor environment is not polluted by pollutants in the drainage vertical pipe, becomes a focus of attention of the majority of users, and also becomes a problem which needs to be solved in the water supply and drainage design and the building construction of the building.
There are two judgment indexes for detecting the sanitary safety performance of the building drainage system nowadays: the first is whether the height of the water seal reaches 50 mm; the second indicator is whether the pressure in the transverse branch exceeds ± 400 Pa. Two judgment methods represented by two judgment indexes have certain limitations, for example, the existing floor drains on the market have various structures, and the direct measurement of the water seal height is difficult; if the pressure of the transverse branch pipe is measured, the pressure can be easily measured under the condition of a laboratory or a laboratory tower, but the measurement in an established high-rise building needs to dismantle the floor of the toilet to be measured and dismantle the existing drainage pipeline, so that the feasibility is low in aspects of construction difficulty, detection cost, detection time and the like.
Meanwhile, a single judgment index is difficult to comprehensively reflect the drainage performance of the drainage system, but the existing detection system capable of reflecting the water seal height, the pressure of the drainage outlet and the wind speed is large in size and fixed. If the drainage performance of the drainage system of one high-rise building is required to be measured, the detection system needs to be arranged in advance, and if the drainage system is used in other high-rise buildings, the detection system needs to be reinstalled, so that the method is not economical in cost. Moreover, it is a problem to be solved in the market today to develop a system capable of collecting and processing data uniformly after detecting each index.
Therefore, how to create a system and a method for testing the sanitation and safety of a movable building drainage system, which have the advantages of simple structure and convenient use, and can conveniently and quickly detect the sanitation and safety performance of the building drainage system, is a problem to be solved by the technical staff in the field.
