RU2624211C1 - Method for intake of underground and submarinary water coming to surface - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: construction of a water header with overflow is implemented by means of fencing aquifer reliefs in the grotto zone with a dam. The water is pumped out to the consumer and the intake setpoint is controlled at the pressure increased relative to the sea in the header, which is created due to raising the water level in front of the dam by means of pressure regulators - bypasses.

EFFECT: preventing the possibility of penetration of seawater and a crack filler into the water header by cracks in the rock, which contributes to the improvement of pumped water quality.

Description

The invention relates to the field of water supply, in particular to methods of abstraction of underground and submarine waters emerging on the surface, which are unloaded in the grotto zone of a rocky seashore.

Known methods for withdrawing surface and submarine waters by capturing sources at the bottom, separating fresh and sea water directly in the discharge zone [1]. But these methods cannot be applied in the grotto zone, where the discharge of groundwater occurs along cracks in both vertical and inclined planes.

The closest in technical essence and the achieved result is a method of abstraction of underground and submarine waters emerging on the surface, including the construction of a catchment area with an overflow at the site of aquifer discharge by means of a fence in the main water discharge zone, pumping water out of it to the consumer and adjusting the intake of a given flow rate [2] .

However, when pumping water from the catchment and adjusting the intake of a given flow rate, sea water can penetrate through cracks in the rock, as well as silty and fine-grained crack filler, which affects the quality of the water pumped to the consumer.

The purpose of the invention is to prevent the possibility of penetration into the catchment through cracks in the rock of sea water and a filler of cracks when pumping water to the consumer and adjusting the intake of a given flow rate, which helps to improve the quality of the pumped water.

This goal is achieved by the fact that in the known method of withdrawing ground and submarine waters that come to the surface, including the construction of a catchment with an overflow by means of a fence in the mainstream grotto area, pumping water out of it to the consumer and adjusting the intake for a given flow rate, pumping out water to the consumer and adjusting the intake a predetermined flow rate is performed with other technological parameters of the process, namely: when the pressure in the catchment is increased relative to the sea, which is created by raising ur vnya water before the dam by means of pressure regulators - bypass and prevents penetration of the water box along the cracks in the rock and sea water crack filler that improves the quality of the pumped water.

It is advisable to create the pressure of the water in the catchment basin slightly exceeding the backpressure of seawater that occurs during tides and stormy sea waves.

As an example of the implementation of the proposed method for the extraction of underground and submarine waters emerging on the surface in Fig. Figure 1 shows the plan of the grotto on the rocky seashore, indicating the dam (1), the location of the aquifer discharge (2) and the catchment (3), and Fig. 2 - longitudinal section along the mainsail with a pipe system (4) for pumping water from the catchment through the dam to the riser (5) with a pressure regulator - bypass (6) that raises the water level (7) in front of the dam, and a submersible pump (8), control which is carried out from the pumping station (9). The pipe system and riser are located on anchor supports (10). Pipes that divert water from the catchment may be located at sea level (11), below or above it.

To maintain the catchment in the dam enclosing the aquifers, a manhole (12) with ladders (13) is arranged.

A comparative analysis of the claimed technical solution with the prototype shows that the proposed method is characterized by the presence of new technological parameters for the operation of pumping water to the consumer and adjusting the intake of a given flow rate and, therefore, meets the criteria of the invention of "novelty".

Comparison of the claimed method not only with the prototype, but also with other known solutions, did not allow to find a solution that has similar characteristics. This allowed us to conclude that the proposed method meets the criterion of "significant differences".

The claimed method of abstraction of surface underground and submarine waters is supposed to be used in the near future for water supply of the coastal areas of the Crimean peninsula.
