Description

Technical Field

[0001] This utility model relates to the field of dam construction reinforcement technology, and in particular to a dam foundation reinforcement and protection structure. Background Technology

[0002] When pouring foundation concrete for dams, especially on dam slopes, a common practice is to first plan the dam's inclination, then fill the slope by laying and compacting a mixture of sand and gravel before pouring concrete. However, the applicant has found in years of construction that while this method is cost-effective and time-efficient, it can lead to soil erosion and excessive water seepage, causing voids on the dam slope. To prevent this, reinforcement bars are sometimes added, but this is costly and time-consuming. While the support and overall integrity are not compromised, internal soil erosion still occurs. Utility Model Content

[0003] The purpose of this utility model is to provide a dam foundation reinforcement and protection structure, which has the advantages of short construction period, low cost and multiple application scenarios.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dam foundation reinforcement and protection structure, comprising:

[0005] A mother template mechanism, wherein the mother template mechanism has open partition openings and closed grid openings;

[0006] The mother formwork mechanism is used for reinforcing dams with low water content. Due to the low water content in this area, sand and gravel are generally used to lay the slope first. Commonly, the paving needs to be protected with baffles in the area from the bottom of the slope to the road surface to ensure that the slope is consistent and that there is no local accumulation. Therefore, the mother formwork mechanism is used.

[0007] In practical use, the closed grid openings are placed horizontally on the edge of the embankment road surface. Then, the closed grid openings are filled with sand and gravel, keeping the open gaps facing the embankment slope. The open gaps are then filled, and the mother template mechanism is added. The process is completed from top to bottom, which ensures that the sand and gravel laid on the embankment slope is uniform.

[0008] Also includes:

[0009] A sub-template mechanism, wherein the sub-template mechanism has a plurality of trapezoidal splicing parts spaced apart along the length direction;

[0010] The sub-formwork structure is used in seasonal rainy areas, especially in rainy areas. The sub-formwork structure is laid from top to bottom. After the bottom of the sub-formwork structure is placed on the upper edge of the slope and fixed, it is released along the slope. In this way, there is elasticity between the multiple trapezoidal splicing parts of the sub-formwork structure. Specifically, geotextile is used for connection. In this way, it can be released in the length direction. After multiple parts are brought together, rods are inserted into the round holes for fixation. The shaded area in the figure is the capillary needle-punched geotextile, which is used for drainage.

[0011] Also includes:

[0012] A composite template, wherein the composite template is integrally formed from a mother template mechanism and a daughter template mechanism;

[0013] The synthetic template setting is suitable for areas with long slopes and abundant rainfall;

[0014] Also includes:

[0015] A low formwork mechanism, wherein the low formwork mechanism is based on the composite formwork and selects 1-3 layers according to construction requirements;

[0016] Suitable for shorter slopes.

[0017] Also includes:

[0018] A perimeter mechanism having multiple composite templates connected together to form a whole.

[0019] Suitable for laying along the length of a slope.

[0020] Furthermore, the composite template includes a splicing plate, which is provided with a plurality of reinforcing ribs. The reinforcing ribs are triangular prisms with their hypotenuses set as arcs.

[0021] Furthermore, the composite template also includes multiple geogrids, which are fixedly connected in sequence, and the connection is made of geonet. A sleeve is also provided between two geogrids located inside the geonet.

[0022] The geogrid installation provides flexibility among multiple geogrids, allowing for adaptive adjustments based on the slope of the paving surface. Furthermore, the geogrid can be extended in length, and the geogrids can be made of plastic with good flexibility, making them lightweight. After installation, they stand upright, allowing for direct filling with sand and gravel. Multiple geogrids are interconnected through interlocking joints, facilitating even sand distribution.

[0023] Furthermore, the composite template also includes a side-block interlock and a second sleeve. The side-block interlock is provided with a lateral opening, the inner cavity of the second sleeve is connected to the lateral opening, and a mating interface is provided between the second sleeve and the geogrid.

[0024] By setting the second sleeve, which is the sub-formwork mechanism, a drainage mechanism can be formed in the local laying area. Moreover, the joint increases the filling volume, which helps the slope to form a blocky area after construction, increasing the stability and firmness of the underlying layer of the overall poured layer.

[0025] Furthermore, the perimeter mechanism includes a locking plate, which is fixedly connected to multiple connecting ribs by a metal rod. One end of each connecting rib is fixedly connected to a dragon-shaped connecting portion, which is formed by multiple open slots that are connected at intervals to elastic connecting portions.

[0026] Furthermore, the edge-enclosing mechanism also includes a capillary needle-punched fabric, one side of which is provided with a side angle, a circular opening on the capillary needle-punched fabric, and a rectangular grid between the capillary needle-punched fabric and the dragon-shaped connecting part, with a guide strip provided in the rectangular grid.

[0027] By setting up the perimeter structure, the perimeter structure is laid along the direction of the embankment. Adjacent perimeter structures are fixed by locking plates, preferably by binding, sintering or hot melting. The rectangular grid is filled first to make the whole structure stable beforehand. Then the capillary needle-punched cloth and open groove are filled. The drainage strip is used to drain the water in the rectangular grid into the lower part. The circular opening can be filled with a rod or a water collection area can be formed. Then the water is discharged uniformly by the capillary needle-punched cloth.

[0028] The technical effects and advantages of this utility model are as follows:

[0029] 1. Setting up the sub-formwork mechanism: The sub-formwork mechanism is used in seasonal rainy areas, especially in rainy areas. The sub-formwork mechanism is laid from top to bottom. After the bottom of the sub-formwork mechanism is placed on the upper edge of the slope and fixed, it is released along the slope. In this way, there is elasticity between the multiple trapezoidal splicing parts of the sub-formwork mechanism. Specifically, geotextile is used for connection. In this way, it can be released in the length direction. After multiple parts are brought together, rods are inserted into the round holes for fixation. The shaded area in the figure is the capillary needle-punched geotextile, which is used for drainage.

[0030] 2. Place the closed grid openings at the edge of the embankment road surface, keeping them horizontal. Then fill the closed grid openings with sand and gravel, keeping the open gaps facing the embankment slope. Then fill the open gaps with sand and gravel, and then lay the mother template mechanism. Lay the grids from top to bottom to ensure that the sand and gravel laid on the embankment slope is uniform.

[0031] 3. By setting up the perimeter structure, the perimeter structure is laid along the direction of the embankment. Adjacent perimeter structures are fixed by locking plates. The best method is binding, sintering and hot melting are both acceptable. The rectangular grid is filled first to make the whole structure stable beforehand. Then the capillary needle-punched cloth and open groove are filled. The drainage strip is used to drain the water in the rectangular grid into the lower part. The circular opening can be filled with a rod or a water collection area can be formed. Then the water is discharged uniformly by the capillary needle-punched cloth. Attached Figure Description
