Problems solved by technology

[0002] At present, no matter whether the underground cables are constructed with strong or weak currents, observation wells, inspection wells, transfer wells, or manhole (hand) wells, the waterproofing is not paid enough attention. Long-term immersion in water often causes personal safety. Cause equipment paralysis to cause great threat and inconvenience to people

Embodiment Construction

[0007] The method of preventing water from being stored in strong and weak electric wells, from figure 1 What you can see: Take the cement pouring forming inspection well as an example, the steps are: 1. In the inspection well, seal the channeling pipe and the main well wall that have been passed into the well with rubber rings, and finally apply sealant, and each single threading pipe is also sealed at the same time. The sealant is good. 2. Make a hole under the main well body and make a water pipe with plastic pipe or other pipes. 3. Install a reverse water stop device (float valve) in the water pipe at the bottom of the main well body while connecting. or electromagnetic valve), 4. Cut a brick under the main well body or pour cement into a storage tank below the horizontal line of the main well, and connect and seal the water pipeline of the main well, and install a water level switch in the main well. 5. Another storage tank Make a pumping pipeline with a plastic pipe or o...

Abstract

The invention relates to a method for preventing water storage in a strong or weak current well. The method comprises the following steps of: building a water storing pond below an original well level; connecting a pipe fitting with the water storing pond below a main body well while arranging a reverse water stopping device in a pipeline which is connected with the water storing pond below the main body well; arranging a water level switch in the water storing pond; arranging a water pumping pipeline which is communicated to the inlet of the main body well and is flush with the water level of the main body well above the other end of the main body well; arranging a water level alarm in the upper side of the water pumping pipeline; and covering a well cover. Due to the adoption of the method, water storage in the improved strong or weak current well is prevented, inflow water is prevented from entering the water storing pond from the lower side of the main body well even the sealing property is poor, and stored water is prevented from entering the well since the water outlet of the main body well is closed by using the reverse water stopping device when the water level in the water storage pond reaches a certain position; and moreover, the alarm is arranged, so that soaking of accumulated water is avoided, and the phenomena of personal injury and equipment damages are avoided.

Description

technical field [0001] The invention relates to a method for preventing water in strong and weak electric wells Background technique [0002] At present, no matter whether the underground cables are constructed with strong or weak currents, observation wells, inspection wells, transfer wells, or manhole (hand) wells, the waterproofing is not paid enough attention. Long-term immersion in water often causes personal safety. Cause equipment paralysis to cause great threat and inconvenience to people. From the perspective of strong and weak current construction, most of the construction is made of bricks, cement pouring, or bottomless wells that are shaped into pits. Take the inspection well formed by cement pouring as an example. After the inspection well is poured, the pipelines from all sides go into the well, and the lines from all sides enter the well. The surrounding inlet pipes are connected to the ground. In this kind of inspection well, due to the threading pipes from...
