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

Prevent the method for water in the strong and weak electricity well

Technical field

The present invention relates to prevent the method for water in the strong and weak electricity well

Background technology

At present underground cable no matter be forceful electric power or light current construction, observe well, manhole, switching well or people's (hand) is Kong Jing, process waterproof and pay little attention to, long period of soaking is in the middle of water, frequent cause personal safety, the lighter causes equipment to paralyse and causes great threat and inconvenience to people.Construct from strong and weak electricity, most constructions are that brick, cement pouring or the well body of the bottomless setting of finalizing the design are lowered to and make in the hole etc.Take cement pouring moulding manhole as example, manhole waters into rear each side pipeline and passes in the well, each side's threading enters in the well, not shutoff of great majority around the borehole wall and the talking over the wire pipe, or shutoff is not tight, and inlet wire pipe and the earth communicate around the well, in this manhole, because each side's penetration pipe, the tube and tube joint sealing is not tight, and is poorly sealed between pipe and the borehole wall, the well lid air vent, well lid and well bore are poorly sealed, these all are the factors into water, and this class well again can't draining after the water inlet, infiltration, long-term manhole or other well long period of soaking are in the middle of water, so need to address this problem especially like this.

Summary of the invention

The problem to be solved in the present invention is how to prevent in the strong and weak electricity well the not method of water, at first below original well water is flat, build a water pond, be connected with the water pond by pipe fitting in the main body downhole, when connecting in main body downhole and pipeline that the water pond is connected the reverse antipriming of installation, then in the water pond, set up water level switch, above the main body well other end, fill the pipeline that draws water pass to import and and main body well face one flat, then set up water level alarm in above the pipeline that draws water, build well lid.

In the strong and weak electricity well behind such method improvement, not at water, although the tube and tube joint sealing is not tight sometimes, pipe is not tight in Well-wall sealer, the well lid air vent, well lid is poorly sealed in well bore, the water that flows into all enters in the water pond from the main well body below, the water pool water level reaches certain position will be float non-return valve jack-up and the well main body below of obturaging, or the water pool water level makes water level switch action shut electromagnetic valve when reaching certain position, closes the main well body delivery port, and water can not enter in the well again, in this well, avoided ponding to invade bubble and line electrical leakage, short circuit has avoided causing the phenomenon of personal injury and device damage.

The specific embodiment

Prevent in the strong and weak electricity well the not method of water, from Fig. 1 finding; Take cement pouring moulding manhole as example, the steps include: that 1. seal with rubber ring and stamp at last fluid sealant passing into talking over the wire pipe and the main body borehole wall in the well at manhole, also fluid sealant is good simultaneously for each root list penetration pipe, 2. below main body well body, make a call to a hole and do a water-filled pipe with moulding pipe or other pipes, 3. check water device (float valve or electromagnetic valve) is installed in the square opening water-filled pipe under main body well body when connecting, 4. square brick is cut one of one or cement pouring and is lower than the following water of main body well water horizontal line pond under main body well body, and main body well water-filled pipe connects sealing, in the main body well, pacify water level switch, water pond other end top with mould manage or other pipes do one draw water pipeline on it plane and main body well face one flat, install water level alarm in 6. above the pipeline that draws water.Cover well lid.

Abovely in conjunction with schematic diagram the present invention has been introduced how to prevent in the strong and weak electricity well the not method of water, but be not limited to the above-described embodiment and examples, can also make without departing from the inventive concept of the premise various variations.

Claims

1. how to prevent in the strong and weak electricity well the not method of water, the method comprises and the steps include: in strong and weak electricity main body well, and talking over the wire pipe and the main body borehole wall that each side is come in seal with rubber ring, then stamp fluid sealant, and each stature fluid sealant glue of each single penetration pipe is good,
