Device for detecting pressure of water in concrete pipe

Abstract

The invention discloses a device for detecting the pressure of water in a concrete pipe. The device comprises a bearing mechanism and a high pressure water supply mechanism, sockets are distributed atthe top ends of steel columns on the two sides respectively, and the steel columns are sleeved with a rear steel cross beam; a jack is perpendicularly connected with the center of the lower portion of the steel cross beam, an opening plugging device is connected with the lower end of the jack, and an air vent and a water inlet are formed in the opening plugging device; and a water reservoir is arranged, a water pump is mounted, and after a water outlet of the water pump is sequentially connected with a pressure pump, a water inlet valve and a pressure meter through a high pressure water inletpipe, the tail end of the water pump is fixed to the water inlet of the opening plugging device in a sealing mode. An opening plugging steel plate is high in strength, not prone to deforming, can plug tightly, and thus the test effect is guaranteed. The device for detecting the pressure of water in the concrete pipe is convenient to mount and dismount, quick and convenient, the test time is shortened, the working efficiency is improved, and the test cost is lowered. The device replaces the operation procedures of a traditional detection device, reduces the investment of labor force and material sources, promotes the health development of scientific test and detection industries, and provides a powerful basis for scientific research.

Description

Technical field: [0001] The invention belongs to the field of building construction and test and detection technology, and in particular relates to a water pressure detection device in a concrete pipe. Background technique: [0002] Reinforced concrete pipes are widely used in urban rainwater and sewage construction, farmland water conservancy construction, electric power and railway engineering construction, and comprehensive pipe gallery construction, among which urban construction consumes the most. [0003] With the continuous acceleration of urbanization, the scale of infrastructure projects under construction is getting larger and larger, and the application of reinforced concrete pipes in rainwater and sewage projects is becoming more and more extensive. According to incomplete statistics, the current domestic annual production capacity of reinforced concrete pipes is 40,000- Between 60,000 kilometers, according to different construction methods, it is divided into re...

Problems solved by technology

[0004] After the pipe is paved in place, it has the characteristics of one-time molding and lifetime use. Once the engineering quality accident is caused by the water seepage of the pipe or other quality problems, it will cause unimaginable social impact.

This puts forward requirements for the quality inspection of reinforced concrete pipes. The current national and industry standards have not yet put forward specific requirements for pipe quality inspection devices, and various regions and inspection centers have not reached a consensus. At present, only a horizontal internal water pipe has been regulated. Pressure detection device and a vertical internal water pressure detection device, there is no further detailed description of the detection device itself, the detection device commonly used in the market is cumbersome to operate, requires a lot of auxiliary equipment and personnel to work, time-consuming and labor-intensive, today's reinforced concrete pipe specifications There are more and more, and the size is getting bigger and bigger. In the construction of large-scale mechanical pipe jacking, the pipe diameter even reaches 3 to 4m, and the weight of the pipe body is getting bigger and bigger. This poses a great challenge to the test and detection auxiliary equipment.
