Problems solved by technology

[0002] For the battery well of the monitoring valve room in the oil and gas long-distance pipeline project, the battery well cover with rectangular structure is used in the continuous rainy area. If the rainfall is too large, the rainwater will leak into the battery well from the side of the well cover, causing the battery to enter water and unable to supply power to related equipment. , the on-site communication was interrupted, resulting in the RTU being unable to communicate normally with the station control system, and the control center was unable to monitor the status of the monitoring valve room, seriously affecting the stable and continuous operation of the station

Embodiment 1

[0035] Embodiment 1, a construction method for a battery well according to the embodiment of the present invention, comprising:

[0036] Step 1, fixing the base 2 in the foundation pit below the ground inside the well body.

[0037] In the above step 1, the base 2 can be placed in the soil layer in the foundation pit, and the part above the base 2 in the foundation pit is backfilled with plain soil layered and compacted, and the plain soil is backfilled on the opposite sides and surroundings of the two bases 2 at the same time . At this time, the layered thickness of plain soil backfill shall not be greater than 300mm, and the compaction coefficient shall not be less than 0.94. Plain soil is natural sedimentary soil that is not doped with other impurities, has a fine and uniform density, and has a certain viscosity. After backfilling with plain soil, the surroundings of the base 2 are made more compact.

[0038] In the above step 1, when there is a backfill soil layer on the...

Abstract

The invention discloses a construction method of an accumulator well. The construction method of the accumulator well comprises the following steps: a base is fixed in a foundation pit below the ground in a well body; a foundation is positioned on the substrate; the top of the foundation is positioned above the ground, and the bottom of the foundation is connected with the top of the substrate; exhaust pipes are embedded in the internal and the external of the well body; after one ends of the exhaust pipes penetrate through the upper part of the foundation, ports of the ends of the exhaust pipes are positioned in the well body and above the ground, and the other ends of the exhaust pipes are leaded to the external of the well body, and ports of the other ends of the exhaust pipes are positioned on the ground and vertically downwards; an accumulator is mounted in accommodating space formed by the substrate and the foundation; a prefabricated conical well lid is put in an opening of thewell body, so that the well lid and the top of the foundation are in contact connection; and the well lid and the opening of the well body are tightly connected. The construction method of the accumulator well has the following beneficial effects: the water leakage phenomenon of the accumulator well caused by excessive rainwater can be prevented; and the accumulator can be guaranteed to continuously supply electricity to electric equipment.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a construction method for battery wells. Background technique [0002] For the battery well of the monitoring valve room in the oil and gas long-distance pipeline project, the battery well cover with rectangular structure is used in the continuous rainy area. If the rainfall is too large, the rainwater will leak into the battery well from the side of the well cover, causing the battery to enter water and unable to supply power to related equipment. , The on-site communication was interrupted, resulting in the failure of the RTU to communicate with the station control system normally, and the control center was unable to monitor the status of the monitoring valve chamber, which seriously affected the stable and continuous operation of the station. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a constr...
