Background
A brick structure well is always used in the application of a water meter well, but the well has a plurality of problems in the using process, including that the construction period is long, the main structure is not tight, serious water accumulation in the well is easily caused, and the like. In order to overcome the defects of the water meter well with the brick structure, the water meter well with a prefabricated member of a steel structure and a concrete structure is designed. The prefabricated water meter well comprises a well body and a well cover, wherein the well body and the well cover are both formed by a reinforced concrete structure and a steel surface beam upright post, and the water meter is placed in the well body. The existing prefabricated water meter well has the following defects: heavy weight, which is inconvenient to carry; when bearing the weight on the well cover, the well cover is easy to collapse, namely the bearing capacity is poor; the water pipe and the water meter well are not hermetically connected or are sealed by coating glue, water can permeate into the water meter well along the surface of the water pipe if the water pipe and the water meter well are not hermetically connected, the water pipe is troublesome to replace if the water pipe and the water meter well are sealed by coating the glue, and the water pipe can be buried after the glue is solidified, so that the construction period is prolonged; the vibration generated on the ground can cause the vibration of the water meter in the well body, and the vibration of the water meter is easy to generate part damage and joint cracking and water seepage. When the existing plastic water meter well is generally installed, concrete is still needed to be paved on the bottom surface of a foundation pit at the bottom, and then the periphery is backfilled after the water meter well is installed. Therefore, underground water can also infiltrate into the well, and the maintenance and meter reading are not convenient later. And the well lid of present plastics water gauge well all adopts plastics to make, often is rolled by the vehicle of passing by on the road and destroys for plastics water gauge well can not the wide use.
