Description

Technical Field

[0001] The utility model relates to the technical field of anti-freezing and heaving of dike engineering, in particular to an anti-freezing and heaving structure of dike engineering. Background Art

[0002] Dike engineering refers to water retaining structures built along rivers, canals, lakes, coasts or the edges of flood-carrying areas, flood diversion areas and reclamation areas. Dikes can be divided into river dikes, river dikes, lake dikes, sea dikes and dikes in low-lying areas of reservoirs and flood storage areas according to their locations; they can be divided into main dikes, branch dikes, sub-dikes, remote dikes, separation dikes, flood-carrying dikes, flood control dikes, dikes (weiyuans) and wave-breaking dikes according to their functions; they can be divided into earth dikes, stone dikes, earth-stone mixed dikes and concrete flood control walls according to their building materials;

[0003] When the climate is too cold, the water-facing slope of the levee is prone to freezing. The freezing expansion will cause the levee to be damaged, making it unable to fully play its role in retaining water, which may have serious consequences. The stability of the levee is very important. When frost heave occurs, the stability of the levee will deteriorate, which may cause the levee to collapse. Utility Model Content

[0004] The utility model aims to provide a frost heave prevention structure for dike engineering to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a base surface, the base surface is an original slope surface, the upper part of the base surface is connected with a transition layer, the upper part of the transition layer is connected with a hard slope protection (mortared stone, concrete) partition layer of the embankment, water control gaps are evenly arranged on the partition layer, the inner wall of the water control gap is fixedly connected with a water outlet valve, and the bottom of the base surface is fixedly connected with an anti-freeze heave structure.

[0006] Preferably, the anti-freeze expansion mechanism includes a stabilizing column, which is evenly arranged at the bottom of the base surface, and the outer surface of the stabilizing column is fixedly connected to an antifreeze pad, and the outer surface of the antifreeze pad is provided with a circular notch, and the bottom of the antifreeze pad is fixedly connected to a partition, and the bottom of the partition is provided with a stirring mechanism.

[0007] Preferably, the top of the stabilizing column is fixedly connected to the bottom of the base surface, and the stabilizing column passes through the top of the antifreeze pad and extends to the bottom.

[0008] Preferably, the stirring mechanism includes a protective cover, the inner wall of the protective cover is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to a rotating column, the outer surface of the rotating column is symmetrically provided with stirring blades, the inner wall of the stirring blades is evenly provided with protruding columns, and the outer surface of the protruding columns is evenly provided with thorns.

[0009] Preferably, the top of the protective cover is fixedly connected to the bottom of the antifreeze pad, and the protective cover is made of concrete.

[0010] Preferably, one end of the stirring blade is fixedly connected to the outer surface of the rotating column, and the thicker end of the spur is fixedly connected to the outer surface of the protruding column.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: a levee project refers to a water retaining structure built along a river, canal, lake, coast or the edge of a floodway, flood diversion area or reclamation area. In order to ensure the stability of the water retaining structure, the stability of the levee structure needs to be ensured. However, when the temperature is below zero degrees Celsius, the capillary phenomenon generated by the foundation soil at the lower layer of the levee project will freeze to form icicles. At the same time, the surface tension of the icicles will absorb the groundwater to continue to rise and freeze again, thereby forming many icicles at the bottom of the levee project. These icicles will affect the safety quality of the levee project. The utility model utilizes an antifreeze layer to avoid the formation of icicles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative ideas are within the scope of protection of the utility model.

[0019] See also Figures 1 to 5, the utility model provides a technical solution:

[0020] like Figure 1-Figure 2 As shown, it includes a base surface 1, which is an original slope surface, a transition layer 2 is connected to the upper part of the base surface 1, an interlayer 3 is fixedly connected to the upper part of the transition layer 2, water control gaps 4 are evenly arranged on the transition layer 2 and the interlayer 3, a water outlet valve 5 is fixedly connected to the inner wall of the water control gap 4, and an anti-freezing expansion mechanism 6 is fixedly connected to the bottom of the base surface 1.

[0021] When implementing embankment projects, the utility model can be used in smaller and narrower rivers. The water outlet valve 5 will control the discharge of water in the soil behind the embankment slope. When the weather is cold, the anti-freezing structure 6 at the bottom will avoid safety problems in the transition layer 2.

[0022] like Figure 3 As shown, the anti-freeze expansion mechanism 6 includes a stabilizing column 61, which is evenly arranged at the bottom of the base surface 1. The outer surface of the stabilizing column 61 is fixedly connected with an antifreeze pad 62. The outer surface of the antifreeze pad 62 is provided with a circular notch 63. The bottom of the antifreeze pad 62 is fixedly connected with a partition 64. The function of the partition 64 is to prevent sand and stones from interfering with the operation of the servo motor 652. The bottom of the partition 64 is provided with a stirring mechanism 65.

[0023] First, the stabilizing column 61 can be completely inserted into the soil, and some materials with relatively large gaps such as crushed stone and gravel can be placed in the antifreeze pad 62. If the gap is large, it can block the rise of capillary water, so that the capillary phenomenon cannot occur and the groundwater cannot move upward. After the capillary water rises to the antifreeze pad 62, it can no longer rise. The groundwater will flow along the side into other canals, thereby avoiding safety problems in the implemented embankment project.

[0024] The top of the stabilizing column 61 is fixedly connected to the bottom of the base surface 1 , and the stabilizing column 61 passes through the top of the antifreeze pad 62 and extends to the bottom.

[0025] like Figure 4-Figure 5 As shown, the stirring mechanism 65 includes a protective cover 651, the inner wall of the protective cover 651 is fixedly connected to a servo motor 652, the output end of the servo motor 652 is fixedly connected to a rotating column 653, the outer surface of the rotating column 653 is symmetrically provided with stirring blades 654, the inner wall of the stirring blades 654 is evenly provided with protruding columns 655, and the outer surface of the protruding columns 655 is evenly provided with thorns 656.

[0026] However, since the original soil is loose, some of the soil will combine with the gravel in the antifreeze pad 62, thereby reducing the gap in the antifreeze pad 62. Therefore, after a period of time, the servo motor 652 will drive the rotating column 653 to rotate, and then drive the stirring blade 654 to rotate, thereby stirring the gravel in the antifreeze pad 62, separating the gravel from the soil and mud, and the soil will flow out from the circular notch 63. Especially for some water-soaked mud, the adhesion is strong. In the process of rotation of the stirring blade 654, the sand and gravel with these mud blocks will collide with the protruding column 655, and the spikes 656 on the protruding column 655 will rub against the gravel, thereby better removing the soil that is prevented from sticking.

[0027] The top of the protective cover 651 is fixedly connected to the bottom of the antifreeze pad 62, and the protective cover 651 is made of concrete.

[0028] One end of the stirring blade 654 is fixedly connected to the outer surface of the rotating column 653 , and the thicker end of the thorn 656 is fixedly connected to the outer surface of the protruding column 655 .

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
