SOJKA JI & T ing., PRAGUE (54) Equipment for increasing the efficiency of the tubular beam under the conditions of the tensioned groundwater regime l

The present invention solves the problem of increasing the efficiency of the tube-type under the conditions of the tense groundwater regime, i. when the high energy horizon of underground water is adversely affected.

According to prior art, waterlogging of agricultural soils can be solved by a dense network of systematic drainage or deep-laid line drainage / drainage slots, or such lands can be disposed of because of the high cost of sanitation. In some cases, the influence of stressed groundwater cannot be ascertained in the pre-project preparation, for example, the survey is carried out during the period of their blatant manifestation, or hydrogeological bases are missing, etc. This leads to a drainage system inadequate efficiency and repeated demand for investment funds. The aforementioned drawbacks are eliminated by reducing the high pressure position of the groundwater pressure horizon. At the same time, by using a well-functioning existing or newly built tubular drain, increasing its effect is ensured by a system of inertial drilling wells that cut through the artesian ceiling and are connected to the superstructure.

Execution of a drained system of vertical relief boreholes across the direction of the flow of groundwater will eliminate the need to build a dense drainage system or deep-drainage notches, or to exclude land from use. The volume of earthwork is reduced considerably. The system can be applied as a new dewatering element, drain with drilling wells, already in the project design or as a complementary device to increase the efficiency of the existing one, for example, in the case of complicated project documentation.

Vertical relief wells, for example 0.10 to 0.15 m, are guided through the drainage groove bottom, in front of it, or from the surface of the ground, to the plumbing groundwater, through the penetration of the arsenic ceiling. It is carried out without equipping the wall. To ensure the stability of the walls and the borehole against hydraulic breakage and the formation of the hydraulically conductive path, it is filled with filter material. This filling is terminated either in the local drainage filter bed, when drilling from the bottom of the drainage groove, or is led above the drainage pipe to a height corresponding to the inlet resistance of the drainage pipe and terminated by an impermeable well bore when drilling from the ground surface. The drill is located as close as possible to the axis of the drainage pipe depending on the borehole brightness. The holes repeat throughout the required length of the drain under waterlogging at sufficient intervals, for example, 3.0 m. In the case of application to two or more parallel drainage chess-pits, care is taken. The system of drained vertical relief wells placed across the flow direction of the tense underground water will allow the preferred rise of the underground tension from the deeper soil horizons and thereby reduce or decrease the flow. it liquidates her tense that caused the waterlogging. Underground water pressure pushed through the vertical relief bore is collected by the pipe drainage system and is no more than 1 961 78
