Detailed Description
An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.
As shown in fig. 1 and 2, an embodiment of the present invention provides a ground treatment structure based on a ground water level, including: the concrete waterproof and anticorrosive foundation comprises a plurality of reinforced concrete piles 3, concrete retaining walls 4, U-shaped water channels 5, waterproof and anticorrosive geomembranes 6, a gravel layer 7, a rammed soil layer 8 and a cement soil layer 9;
The use method and the working principle are as follows: set up perpendicularly in the flow direction of groundwater course 1 through concrete retaining wall 4, and U type water course 5 is regional around building foundation 2, change the water route flow direction with the groundwater flow under building foundation 2, avoid groundwater to cause the influence to building foundation 2 is regional, keep apart groundwater through waterproof anticorrosive geomembrane 6, avoid groundwater to cause the influence to building foundation 2, simultaneously avoid rammed soil layer 8 in the building foundation 2 to sink through metalling 7, influence the steadiness of building foundation, soil cement layer 9 improves soil, avoid soil to be affected with damp and flow, strengthen building foundation's holding power and steadiness simultaneously, a plurality of reinforced concrete piles 3 and soil cement layer 9, rammed soil layer 8 and metalling 7 are connected and are played the support to the building jointly, make building foundation firm.
The foundation treatment structure based on the underground water level has a stable structure, is not influenced by underground water, and ensures the safety of the building.
The soil in the tamped soil layer 8 fills the gaps of the gravel layer 7, so that the gravel layer 7 is structurally stable.
The thickness of the cement soil layer 9, the thickness of the rammed soil layer 8, the thickness of the gravel layer 7 and the diameter and the length of the reinforced concrete pile 3 are all related to the number of layers and the height of the building, and the height of the concrete retaining wall 4 is related to the diameter of the underground water channel 1 along with the corresponding increase of the thickness, the diameter and the length of the number of layers and the height of the building.
As shown in fig. 1, the building foundation further comprises an annular drainage ditch 10, wherein the annular drainage ditch 10 is arranged at the outermost side of the building foundation, and the bottom of the annular drainage ditch 10 is positioned in the gravel layer 7.
The annular drainage ditch 10 is used for discharging the rainwater on the waterproof and anticorrosive geomembrane 6 through the gravel layer 7, and avoids the influence of rainwater runoff on the periphery of the building foundation on the building foundation.
The area of waterproof anticorrosive geomembrane 6 is greater than the area that annular escape canal 10 surrounded, discharges the rainwater around the annular escape canal 10, avoids the rainwater around the ground to exert an influence to the ground, has ensured the steadiness of building the ground.
The diameter of the U-shaped water channel 5 is larger than that of the underground water channel 1.
Therefore, underground water can be quickly drained away when passing through the building foundation, and the influence of the rising of the underground water level on the building foundation is avoided.
The waterproof and anticorrosive geomembrane 6 is prepared by coating acid and alkali resistant coatings on the front and back surfaces of the waterproof geomembrane.
The acid-alkali resistant coating can prevent acid and alkali in underground water from corroding the geomembrane.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
