Problems solved by technology
[0003] Existing patents reduce surface runoff and accumulated water capacity by improving the water storage capacity of the aquifer, but in soil layers with low formation permeability coefficients, the effect of this method is not obvious; some patents use a complete set of systems The equipment collects the rainwater infiltrated into the ground, stores the rainwater in the underground storage tank, and then uses the collected rainwater through the pumping equipment, which not only has a high cost but also destroys the original ecological environment, and the application effect is poor; For example, grass-planting bricks are laid on the sidewalks of residential areas to improve the water accumulation environment, but grass-planting bricks cannot improve the permeability of the stratum, and the accumulated water will overflow in the event of heavy precipitation

Embodiment Construction
[0034] The present invention is described in detail below in conjunction with accompanying drawing:
[0035] A prefabricated leakage column device for accelerating ground water seepage, comprising a leakage column cuboid 1, a square prism 2, a water seepage hole 3, a water collection hole 4, a pyramid 5, and a drainage hole 6. During construction, the leakage column is to be laid at the position , remove the soil layer at a certain depth on the surface, and the removed thickness is equal to the distance from the top of the seepage column cuboid 1 to the bottom surface of the square prism 2, and then construct the seepage column according to the row spacing of 1m×1m. During construction, the seepage The leakage column is pressed into the formation, the bottom surface of the square column 2 of the leakage column is in contact with the ground after the surface soil has been removed and squeezed tightly, and then backfilled with pulverized coal slag 7 to a height equal to the top o...

The invention discloses a device and construction method for a prefabricated seepage column. The device for the prefabricated seepage column comprises a cuboid, the bottom end of the cuboid is pyramidic, and the neck of the cuboid is integrally sleeved with a quadrangular prism; a plurality of water seepage holes penetrating through the cuboid are uniformly formed in the length direction of the cuboid of the seepage column; a plurality of collecting holes communicating with the corresponding water seepage circular holes are formed in all the horizontal positions, corresponding to the outer sides of the cuboid, of the top surface of the quadrangular prism of the seepage column; a plurality of drain holes communicating with the water seepage circular holes are uniformly formed in the cuboid under the quadrangular prism in the width direction of the cuboid.
Description
technical field [0001] The invention relates to a prefabricated seepage column device for accelerating ground water seepage and a construction method thereof, belonging to the technical field of construction engineering. Background technique [0002] With the rapid increase of urban buildings, the land around the buildings is mixed with many building debris or the movement of construction machinery makes the surface soil layer stiff, destroying the original performance of the soil layer, resulting in many For example, in the rainy season, the surface runoff increases, causing scouring damage to buildings and road surfaces; ground water is not easy to infiltrate into the stratum, which brings inconvenience to people's travel and transportation; the recharge of atmospheric precipitation in the stratum decreases, which affects land plants. water supply, and at the same time lower the groundwater table. Therefore, it is of great significance to improve the ecological environmen...
