Description

Technical Field

[0001] The present invention relates to the technical field of dam danger treatment, and in particular to equipment and method for treating dam seepage landslide danger. Background Art

[0002] Scattered infiltration is a common hazard in water conservancy projects. When the water level of rivers and lakes rises, the infiltration line in the dam rises, and the seepage water escapes from the back slope of the dam or near the foot of the back slope. This phenomenon is called scattered infiltration, commonly known as "dike sweating". During scattered infiltration, the soil at the place where the scattered infiltration escapes is moist or soft. If scattered infiltration occurs on the side slope of the back slope of the dam, it often causes landslides on the back slope. In severe cases, it leads to accidents such as dam breach and dam collapse, which are very harmful.

[0003] The traditional method of dealing with diffuse seepage hazards is to first open a reverse filtration and seepage ditch on the back slope of the dam or use sandbags for back pressure, and then take anti-seepage measures on the front slope of the dam as needed. However, this method has the disadvantages of low treatment efficiency and the need for a large amount of sand and gravel and other materials. In addition, when the back slope of the dam is steep and the diffuse seepage source is located in the middle of the slope, the use of sandbags for back pressure may aggravate the landslide on the back slope due to the gravity of the sandbags, which poses a great risk.

[0004] Therefore, if a new technology for dealing with dangerous dam seepage landslides is invented, which is easy to carry, simple, fast and efficient to implement, and whose auxiliary materials can be obtained on site, it will be of great significance to protecting people's lives and property losses.

[0027] As a general inventive concept, the present invention also proposes a method for handling dangerous situations of dam diffuse seepage landslides, using any of the above-mentioned dangerous situation handling equipment for dam diffuse seepage landslides, comprising the following steps:

[0028] S1. Obtain field data, including the location of the seepage, the width of the dam top, the distance from the water level on the dam upwelling slope to the dam top, and the distance from the seepage location to the dam top;

[0029] S2. Place the anti-seepage drum and the filter drum in place on the top of the dam, determine the positions of the first buckle and the second buckle on the second mesh and the first mesh respectively according to the obtained field data, and buckle them firmly to complete the connection between the anti-seepage drum and the filter drum;

[0030] S3. Roll the anti-seepage drum and the filter drum along the corresponding slope to the bottom of the upstream slope and the bottom of the downstream slope of the dam, respectively, so that the first mesh and the second mesh are unfolded and covered on the upstream slope and the downstream slope of the dam;

[0031] S4. Fill each compression hose with water until the internal water level is 0.5±0.05m higher than the external water level, and then cover the water filling hole cover;

[0032] S5. Arrange several unfilled back pressure water belts next to the second mesh to cover the scattered leaching escape; arrange several unfilled weighted water bags on the first mesh;

[0033] S6. Fill each counter-pressure water hose and counterweight water bag with water. When filling with water, first follow the principle that the total weight of each counter-pressure water hose and the total weight of each counterweight water bag are basically the same, until each counter-pressure water hose is full, cover the water filling hole cover, and then continue to fill the counterweight water bag with water. During the process, observe the sliding tendency of the counterweight water bag and the counter-pressure water hose, and adjust the total weight of the counterweight water bag until each counter-pressure water hose is in a static friction state tending to slide upward along the back slope of the dam.

[0034] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0035] (1) In the present invention, the first mesh sheet is unfolded and covers the upstream slope of the dam. By filling the compression water belt therein with water, when the water level in the compression water belt is higher than the water level of the river or lake on the upstream slope of the dam, the water pressure in the compression water belt will produce a compression effect on the anti-seepage membrane cloth covering the upstream slope of the dam, so that the anti-seepage membrane cloth is closely attached to the upstream slope of the dam, reducing contact leakage along the bottom of the anti-seepage membrane cloth, and playing an anti-seepage function.

[0036] (2) In the present invention, the second mesh is unfolded and covers the back slope of the dam, and a back pressure water belt is hung on the second mesh at the place where the seepage on the back slope escapes. The back filter cloth and the back pressure water belt work together to achieve the functions of back filtration and pressure seepage. By adopting a back pressure water belt in the shape of a gourd string, when several back pressure water belts are arranged closely together, a gap is formed between adjacent back pressure water belts at the reduced diameter of the gourd string, which facilitates the discharge of seepage water, reduces the osmotic pressure acting on the back pressure water belt, and creates friction between the back pressure water belt and the back slope of the dam.

[0037] (3) A plurality of weighted water bags and a plurality of counter-pressure water hoses are respectively hung on the first mesh and the second mesh connected by buckles, and the total weight of the weighted water bags is greater than the total weight of the counter-pressure water hoses. The tensile force is transmitted through the first mesh and the second mesh connected to each other, which will generate an upward force (toward the top of the embankment) on the counter-pressure water hose along the backwater slope, thereby offsetting the downward sliding force on the backwater slope of the embankment and playing the role of preventing the backwater slope from sliding.

[0038] (4) The fillers required for compaction, counterpressure and counterweight in the present invention are all water, which can be taken on site and filled conveniently and quickly.

[0039] (5) The mesh of the rope net structure used in the present invention is used as the attachment base for covering (such as anti-seepage membrane cloth, reverse filter cloth) and hanging (such as counterweight water bag, reverse pressure water hose). On the one hand, it is convenient to wind and reel it around the reel, and on the other hand, it provides sufficient strength to prevent the anti-seepage membrane cloth and reverse filter cloth from breaking. In addition, it is also convenient to cooperate with the buckle ring to realize the quick connection of the free ends of the first mesh and the second mesh, as well as the installation of the buckle of the counterweight water bag and the reverse pressure water hose, and it is convenient to flexibly adjust the overlapping position of the free ends of the first mesh and the second mesh (i.e., the overlapping length) and the hanging position of the reverse pressure water hose according to the field data such as the width of the top of the dam, the water level of the dam's upstream slope, and the position of the diffuse seepage escape.

[0040] (6) The anti-seepage drum and the filter drum in the present invention can be rolled into a cylindrical shape when not in use, which is convenient for storage, transportation and movement; when in use, they can be rolled in the opposite direction and spread out, which is convenient for combining with the application scenario where the slope of the dam is a slope, and they are rolled down from the top of the dam in accordance with the terrain, and the first mesh sheet and the second mesh sheet are spread out on the corresponding slope of the dam.

[0041] (7) The present invention aims at the occurrence mechanism of the danger of diffuse infiltration landslide "caused by water", follows the principle of using local materials, and develops a complete set of equipment for dealing with the danger of diffuse infiltration landslide, so as to achieve the effect of "treating danger with water". It integrates the comprehensive functions of anti-seepage, anti-filtration, pressure seepage and anti-slip, and has an ingenious working principle. It can be applied to the rapid disposal of the danger of diffuse infiltration landslide on dams. The equipment structure is simple to manufacture, the materials used are inexpensive, easy to transport and carry, and the installation and implementation are fast and efficient. The filling material can be taken locally, has strong applicability, can be reused many times, and is highly economical. It can be used as flood control reserve materials for water conservancy project management units, and has broad prospects for promotion and application.

[0051] The drawings are for illustrative purposes only and should not be construed as limiting the present patent;

[0052] In order to better illustrate the present embodiment, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0053] It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings;

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be said that the internal connection of two elements is connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "front", "back", etc. is based on the orientation or position relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0055] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0056] like Figure 1 , Figure 2 As shown, the dam diffuse seepage landslide hazard treatment equipment of an exemplary embodiment of the present invention includes an anti-seepage drum, a reverse filter drum, eight water-filled back pressure water hoses and four water-filled counterweight water bags. It should be noted that the number of the back pressure water hoses and counterweight water bags in the present invention is not limited and can be configured according to actual conditions as long as the technical effects of the present invention can be achieved. In addition, the arrangement range of the back pressure water hose should be able to cover the diffuse seepage escape range, and it is preferable to expand 1m around the diffuse seepage escape range.

[0057] The anti-seepage reel comprises a first reel 101 and a first mesh sheet 103 rolled up on the first reel, and an anti-seepage membrane cloth 105 is bonded to the bottom surface of the first mesh sheet, and a plurality of water-filled compression hoses 106 are bonded to the top surface. In some embodiments, to facilitate rolling and unrolling of the anti-seepage reel, first side wheels 102 are coaxially fixed at both ends of the first reel 101, and the diameter of the first side wheel is not less than the diameter of the first mesh sheet 103 after rolling up on the first reel 101.

[0058] The reverse filter drum includes a second reel 201 and a second mesh sheet 203 rolled up on the second reel, and a reverse filter cloth 205 is sewn on the bottom surface of the second mesh sheet. In some embodiments, to facilitate rolling and unrolling of the reverse filter drum, second side wheels 202 are coaxially fixed at both ends of the second reel 201, and the diameter of the second side wheels is not less than the diameter of the second mesh sheet 203 after rolling up on the second reel 201.

[0059] During implementation, the anti-seepage drum and the anti-filtration drum are first placed on the top of the dam, and the free end of the first mesh 103 and the free end of the second mesh 203 are overlapped by an appropriate length and then detachably fixedly connected. Then the anti-seepage drum is rolled down the slope from the top of the dam to the bottom of the dam's upstream slope, so that the first mesh 103 is unrolled and unfolded to cover the upstream slope of the dam. After being filled with water, the multiple compression hoses 106 on the first mesh can compress the anti-seepage membrane cloth 105 to make it close to the upstream slope of the dam, thereby realizing the anti-seepage function. The anti-filtration drum is rolled down the slope from the top of the dam to the bottom of the back slope of the dam, so as to unwind the second mesh sheet 203 to unfold it and cover the back slope of the dam. The anti-filtration cloth 205 on the second mesh sheet covers the diffuse seepage range of the back slope of the dam, and eight anti-pressure water belts are arranged and hung on the second mesh sheet next to the diffuse seepage location. The eight anti-pressure water belts cover the diffuse seepage location. In this way, the eight anti-pressure water belts and the anti-filtration cloth can work together to achieve the functions of anti-filtration and pressure seepage. In addition, four weighted water bags are hung side by side on the first mesh sheet 103 at the top of the front slope of the dam, and the total weight of the four weighted water bags after being filled with water is greater than the total weight of the eight anti-pressure water belts after being filled with water, and the eight anti-pressure water belts are in a static friction state when they are about to slide upward along the back slope of the dam. In this way, the sliding force of part of the back slope of the dam can be offset to achieve the function of anti-slip.

[0060] In some embodiments, the first mesh 103 and the second mesh 203 are both rope net structures, which can be made of ropes made of materials such as polyethylene, and are rectangular when spread out. Of course, the first mesh and the second mesh can also be made of materials with other chemical and physical properties, mechanical properties, etc. that can adapt to the use scenarios and use requirements of the present invention. Among them, one end of the first mesh 103 in the length direction is a fixed end fixed to the first reel 101 by rope binding, and the other end is a free end, and the end of the free end is provided with a plurality of first buckles 104; one end of the second mesh 203 in the length direction is a fixed end fixed to the second reel 201 by rope binding, and the other end is a free end, and the end of the free end is provided with a plurality of second buckles 204. When the first mesh 103 and the second mesh 203 need to be connected, the free ends of the two are overlapped with each other by an appropriate length, and then a plurality of first buckles 104 are buckled on the corresponding positions of the second mesh 203 and fastened securely. A plurality of second buckles 204 are buckled on the corresponding positions of the first mesh 103 and fastened securely. The connection is simple and convenient for disassembly and adjustment.

[0061] It can be understood that, since the first mesh 103 and the second mesh 203 are connected via wide edges, the widths of the first mesh 103 and the second mesh 203 in the present invention can be the same or substantially the same, and of course the same is preferred.

[0062] In some embodiments, the anti-seepage membrane 105 is as wide as the first mesh 103, which is conducive to ensuring effective anti-seepage and facilitating the side-by-side joint use of two or more devices of the present invention. In order to save material usage and adjust the covering position of the first mesh according to site conditions when the anti-seepage reel is used, the length of the anti-seepage membrane 105 is less than the length of the first mesh 103, for example, it can be 2 to 3 meters less than the length of the first mesh 103, and when the anti-seepage membrane 105 is unfolded and covered on the water-facing slope of the dam with the first mesh, one end of it close to the first reel 101 is located at the bottom of the water-facing slope of the dam, and the distance from the first reel 101 can be about 0.5 meters, and the other end is close to the top of the water-facing slope of the dam and is above the water surface to ensure effective anti-seepage.

[0063] The compression hose 106 is preferably in the shape of a strip, which is easy to process and shape. A plurality of compression hoses 106 are evenly spaced and arranged on the first mesh sheet 103 in parallel with the length direction, and the arrangement range of the plurality of compression hoses 106 is basically the same as the range of the impermeable membrane cloth 105, and the two ends of each compression hose 106 are close to or aligned with the corresponding edge of the impermeable membrane cloth 105 to ensure the compression effect on the impermeable membrane cloth after filling with water. In addition, when each compression hose 106 is unfolded with the first mesh sheet 103 and laid on the water-facing slope of the dam, one end of each compression hose 106 away from the first reel 101 is higher than the water surface, and a compression hose water filling hole 107 with a hole cover is provided at the end, which is convenient for filling with water to construct a water level difference (water pressure difference) inside and outside the compression hose.

[0064] In some embodiments, the reverse filter cloth 205 is as wide as the second mesh 203, so that when the range of leaching is large and exceeds the width of the second mesh, two or more devices of the present invention can be used side by side. In order to save material consumption and adjust the covering position of the second mesh according to site conditions when the reverse filter drum is used, the length of the reverse filter cloth 205 is less than the length of the second mesh 203, for example, it can be 2 to 3 meters less than the length of the second mesh 203, and when the reverse filter cloth 205 is unfolded and covered on the back slope of the dam with the second mesh, one end of it close to the second reel 201 is located at the bottom of the back slope of the dam, and the distance from the second reel 201 can be about 0.5 meters, and the other end is close to the top of the back slope of the dam to fully cover the range of leaching.

[0065] like Figure 3 As shown, after the back-pressure water hose is filled with water, its body 301 is in the shape of a gourd string, and a back-pressure water hose filling hole 303 equipped with a hole cover is provided at the end away from the second reel 201, and a back-pressure water hose drainage hole 304 equipped with a hole cover is provided at the end close to the second reel 201. By adopting the back-pressure water hose in the shape of a gourd string, when several back-pressure water hoses are arranged closely, a gap can be formed between adjacent back-pressure water hoses at the reduced diameter of the gourd string, which is convenient for the seepage water to be discharged therefrom, thereby reducing the penetration pressure acting on the back-pressure water hose. A plurality of back-pressure water hose buckle rings 302 are provided on the bottom surface of the body of each back-pressure water hose, and are arranged in two rows on both sides of the bottom surface of the body along the extension direction of the gourd string, respectively, for hanging the back-pressure water hose on the second mesh sheet 203.

[0066] A weighted water bag filling hole 403 with a hole cover is set in the middle of the top of the bag body 401 of each weighted water bag, and a weighted water bag drainage hole 404 with a hole cover is set at the bottom; and a weighted water bag buckle 402 is set at each of the two ends of the top of the bag body 401 for hanging the weighted water bag on the first mesh 103.

[0067] After filling with water, the total weight of the counterweight water bags hung on the first mesh 103 should be greater than the total weight of the back-pressure water hoses hung on the second mesh 203. During implementation, it can be controlled at 1.5 to 2 times according to the slope gradient and the roughness of the slope of a conventional earth-rock dam. The specific control is based on the on-site observation of the relative stability of the sliding trend of the counterweight water bags and the back-pressure water hoses.

[0068] The present invention also provides a method for handling dangerous situations of dam diffuse seepage landslide, which can adopt any of the above-mentioned dangerous situations of dam diffuse seepage landslide handling equipment, and comprises the following steps:

[0069] S1. Obtain on-site data, such as: find out the location of the seepage, and measure the width of the dam top, the distance from the water level of the dam upwelling slope to the dam top, the distance from the seepage point to the dam top, and other on-site dimensions;

[0070] S2. Place the anti-seepage drum and the reverse filter drum in place on the top of the dam, roll the anti-seepage drum and the reverse filter drum in reverse direction to unfold the first mesh and the second mesh, determine the positions of the first buckle ring and the second buckle ring on the second mesh and the first mesh respectively according to the obtained field data, and buckle them firmly to complete the connection between the anti-seepage drum and the reverse filter drum;

[0071] S3. Roll the anti-seepage drum and the filter drum along the corresponding slope to the bottom of the upstream slope and the bottom of the downstream slope of the dam, respectively, so that the first mesh and the second mesh are unfolded and covered on the upstream slope and the downstream slope of the dam;

[0072] S4. Open the water filling hole covers of each compressed water hose in turn to fill water. When the water level inside each compressed water hose is about 0.5m (0.5±0.05m is recommended) higher than the water level on the front slope of the external dam, stop filling water and cover the water filling hole covers;

[0073] S5. Arrange several unfilled counter-pressure hoses and fasten them on the second mesh at the place where the seepage escapes. The arrangement range of the several counter-pressure hoses should be able to cover the range of the seepage escape, and it is better to extend 1m around the range of the seepage escape; fasten several unfilled weighted water bags side by side on the first mesh at the top of the water-facing slope of the dam;

[0074] S6. Open the water filling hole covers of each counter-pressure water hose and counterweight water bag in turn to fill them with water. When filling with water, the total weight of each counter-pressure water hose and the total weight of each counterweight water bag should be basically the same; after the counter-pressure water hose is fully filled, cover the water filling hole covers, and then continue to fill the counterweight water bags with water; when the total weight of each counterweight water bag is greater than the total weight of each counter-pressure water hose to a certain extent, under the action of gravity, each counterweight water bag will slide downward along the upstream slope of the dam, and at the same time, the first mesh and the second mesh connected to each other will drive each counterweight water bag to slide upward along the downstream slope of the dam. When such a sliding trend is found, stop filling the counterweight water bag with water immediately and open the drainage hole cover of one of the counterweight water bags to drain some of the weight, so that the counterweight water bag and the counter-pressure water hose are stable (each counter-pressure water hose is in a static friction state tending to slide upward along the downstream slope of the dam). Due to the different slopes and roughness of the dam slopes, the multiple of the total weight of the counterweight water bags for maintaining the stability of the counterweight water bags and the back-pressure water hoses to the total weight of the back-pressure water hoses is not a fixed value.
