Description
Technical Field
The utility model relates to a long distance prevention of seepage type culvert structure.
Background
In the engineering construction of highways, water conservancy, municipal works and the like, concrete culverts are often used as underground drainage channels (water passing channels) or pipeline galleries. Under the influence of the formwork erecting and dismantling pouring process, the culvert is generally poured in two times at the construction joint of the wall toe. For the long-distance culvert, sectional pouring is generally carried out for reducing the influence of uneven settlement and displacement. The culvert is buried underground and is influenced by erosion of underground water, flowing water in a pore passage or other complex water bodies for a long time, water seepage of the culvert becomes a common disease, great hidden danger is brought to the safety and stability of surrounding soil bodies or upper structures, sinking and collapse of upper roads or dams can be caused in serious cases, and a large amount of manpower, material resources and financial resources are input to detect and repair various culverts every year in China. Therefore, how to improve the seepage-proofing performance of the culvert is of great importance.
Based on the problems, a long-distance anti-seepage culvert structure with a high anti-seepage effect is designed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a long distance prevention of seepage type culvert structure with higher prevention of seepage effect.

Preferably, the bottom position of the abutted seam of the adjacent culvert body is provided with a pad beam.
Seepage-proofing scheme for wall
Reason analysis: the water seepage inducement of the wall body mainly comes from the defects of concrete construction quality of the culvert, such as concrete cracks, rotten roots and the like, and the defects that the wire drawing rod hole is not tightly blocked by the template form a water seepage channel under the erosion and freeze thawing effects of water bodies inside and outside the culvert for a long time.
And (4) countermeasure: the epoxy asphalt paint is coated on the inner wall of the culvert for 2 times, has good water resistance and weather resistance, is suitable for large-area concrete corrosion prevention, and can effectively prevent the inner wall from being eroded by flowing water in the holes of the culvert.
2 times of epoxy asphalt paint, asphalt waterproof coiled materials and a protection plate are applied to the outer wall of the culvert, the waterproof performance and the flexibility of the anti-seepage coiled materials are good, the non-uniform settlement and the displacement within a certain range between long-distance culvert sections can be met, the asphalt waterproof coiled materials can be protected to be damaged by the protection plate, and the 3 layers of protection of the outer wall of the culvert can effectively prevent the corrosion of complicated water bodies such as groundwater and the like outside the culvert.
Seepage-proofing scheme for construction joints
Reason analysis: the construction joint is a weak area of the culvert wall body, and the construction joint is easy to form a water seepage channel under the action of erosion and freeze thawing of water bodies inside and outside the culvert for a long time.
And (4) countermeasure: on the basis of the scabbling of the old concrete surface of the construction joint, a rubber waterstop is buried, so that a water seepage channel at the construction joint of the culvert wall can be directly blocked. The rubber water stop has elasticity, wear resistance, aging resistance and tear resistance, and is strong in adaptive deformation capacity and good in waterproof performance.
Anti-seepage scheme for segment seams
Reason analysis: the reason for water seepage of the segment joints is mainly that the segment joints deform excessively due to uneven settlement and displacement of adjacent culvert sections, and water-permeable gaps appear.
And (4) countermeasure: and (3) embedding a rubber water stop at the joint of the segment, wherein the rubber water stop can directly block the water seepage channel at the joint of the segment of the culvert according to the principle of the second scheme. The rubber waterstop can adapt to uneven settlement and displacement of adjacent culvert sections.

Seepage-proofing scheme between culvert and surrounding soil body
Reason analysis: as the culvert construction changes the flowing space of the in-situ water body at the culvert, the water flow (cross flow) parallel to the length direction of the culvert can carry out reciprocating flow erosion between the culvert and the surrounding soil body along with the water level change at two sides of the culvert, the erosion loss of the surrounding soil body can aggravate the uneven settlement and displacement of the culvert, and even can cause the settlement and collapse of upper structures such as municipal roads or water conservancy dams (reservoirs).
The concrete seepage-blocking rings are arranged on the periphery of the culvert and are perpendicular to the length direction of the culvert at proper intervals, so that the transverse flow erosion between the culvert and the surrounding soil body can be effectively blocked, the transverse flow is blocked, and a continuous channel cannot be formed.
Meanwhile, the seepage blocking ring is favorable for the overall stability of the culvert, reduces uneven settlement and displacement of the culvert under the combined action of the seepage blocking ring and the pad beam, and reduces the water seepage risk of the segment joints.
The utility model has the advantages that: this device can guarantee the wholeness of culvert after the installation is accomplished, avoids the upper and lower dislocation of adjacent culvert, can play effectual water-proof effects through the rubber waterstop buried underground, and the simple structure of this device, low cost is fit for using widely.
