Description

Technical Field

[0001] The invention relates to the technical field of emergency rescue and flood prevention and disaster reduction of water conservancy projects, and in particular to an emergency rescue fast-assembly type spillway device suitable for small and medium-sized earth-rock dams. Background Art

[0002] Small and medium-sized reservoir earth-rock dams are important water conservancy facilities that play an important role in flood control, irrigation, and water supply. They are widely used due to their simple structure and good economy. However, constrained by traditional design concepts and regulatory restrictions, most earth-rock dams lack effective anti-scour protection structures on the surface of the dam body, and their overtopping and collapse prevention capabilities are seriously insufficient when encountering super-standard floods. In recent years, due to the influence of extreme weather, super-standard flood events have occurred frequently, resulting in the overtopping and collapse of small and medium-sized earth-rock dams, which seriously threatens the lives and property safety of the people in the downstream areas.

[0003] Traditional spillway design is usually a permanent reinforced concrete structure with good flood discharge capacity, but it has a long construction period and high cost, and is mostly used in large or backbone dam projects. In the early construction of small and medium-sized earth-rock dams, due to economic and construction process limitations, the dam body flood discharge facilities were imperfect and the quality was uneven. In addition, the flood design standards were relatively low, making it difficult to meet the flood discharge needs under super-standard floods. At present, there are mainly the following technical means to deal with sudden dangerous situations caused by super-standard floods. The first is to temporarily raise the dam body, but such engineering measures require a large amount of earth and stone materials, which is difficult to meet the timeliness of rescue, and due to the tight construction period, the quality is difficult to effectively guarantee; the second is to lay waterproof materials on the downstream dam surface or add retaining walls and geomembranes to form a temporary flood discharge channel, but under the action of high head and high flow rate water, the anti-scouring performance of geomembranes is limited, and the overall paving of the downstream dam surface is not conducive to controlling the downstream water flow. Although the addition of retaining walls can guide the downstream water flow, the engineering measures are relatively cumbersome and cannot adapt well to the dam body forms such as multi-level horseways and different slopes; in addition, some projects use excavation of diversion troughs and laying of geotextile bags filled with fast-setting concrete to form temporary spillways, but this measure has a large disturbance to the dam body, low rescue efficiency, and is difficult to achieve rapid deployment in emergency situations.

[0004] In view of the high standards required for the timeliness of emergency rescue and the efficiency of relevant technical means and construction equipment, the development of economical, efficient, rapidly deployable emergency spillway technology that can adapt to a variety of slopes and dam shapes has become a key research direction for the safety protection of small and medium-sized earth-rock dams.

Adjacent dam top water retaining walls are connected by a spillway connection module 3. The above-mentioned spillway connection module 3, the spillway deformation module 4, and the spillway assembly module 5 form a sloped water discharge channel.

[0029] Specifically, the water retaining plate assembly module 1 includes a first bottom plate 11 located on the top of the dam, and a first vertical plate 12 is arranged in the middle of the first bottom plate 11 and is arranged along the dam body in the horizontal direction. In order to improve the structural stability, a first reinforcing rib 13 is arranged on the first vertical plate 12, a first water-facing support member 14 is arranged between the water-facing surface of the first vertical plate 12 and the first bottom plate 11, and a first water-receiving support member 15 is arranged between the water-receiving surface of the first vertical plate 12 and the first bottom plate 11. Usually, the length of the first water-facing support member 14 is greater than the first water-receiving support member 15, the purpose is to make the water retaining plate assembly module 1 stably sit on the flat top of the dam with the help of the dead weight of the flood. Furthermore, sandbags can also be placed in the gap of the first water-facing support member 14. In order to facilitate the connection with other assembly modules, a first connector 16 of a mortise and tenon structure is also arranged on both sides of the first vertical plate 12. In this embodiment, the first connecting member 16 includes a plug-in slot and a plug-in rod arranged at the end of the first vertical plate 12.

[0031] The spillway connection module 3 is also located on the dam top, and includes a third bottom plate 31 and a pair of third vertical plates 32 arranged thereon.

The above-mentioned flat-plate connecting member corresponds to the position of the flat-plate connecting member of the water retaining plate connection module 2, and is arranged in the middle of the third bottom plate 31.

[0032] The spillway deformation module 4 is installed at the corner of the dam slope. In order to adapt to the corner of the dam slope, it adopts a fourth upper bottom plate 411 and a fourth lower bottom plate 412 that are hingedly connected, wherein a pair of fourth upper vertical plates 421 are arranged on the fourth upper bottom plate 411, and a pair of fourth lower vertical plates 422 are arranged on the fourth lower bottom plate 412.

The fourth connecting member 46 adopts a mortise and tenon type connecting member that matches the mortise and tenon type connecting member of the third connecting member 35 in the spillway connection module 3. In order to improve the grip, a gripping tooth 47 is also provided on the periphery of the fourth lower bottom plate 412.

[0033] The spillway assembly module 5 can be arranged on the dam top, the dam slope and / or the dam bridleway, that is, on the plane and inclined surface without corners. It includes a fifth bottom plate 51, on which a fixing tooth 52 and an anchor hole 53 for connecting an anchor rod are arranged. A pair of fifth vertical plates 54 are also arranged on the fifth bottom plate 51, and the two fifth vertical plates 54 are connected by one or more energy dissipation plates 55, and the fifth vertical plate 54 is provided with a fifth reinforcing rib 56, and the back side of the fifth vertical plate 54 is provided with a fifth support member 57 connected to the fifth bottom plate 51, and the upstream and downstream sides of the fifth vertical plate 54 are both provided with a fifth connecting member 58. The above-mentioned fixing teeth 52 are usually arranged on the periphery of the fifth bottom plate 51 to improve the anti-slip force and grip. The above-mentioned anchor hole 53 is located on the back side of the fifth vertical plate 54, that is, outside the spillway. For steeper or soft slopes, anchor rods can be driven into the anchor holes 53 to increase the stability of the structure. The energy dissipation plate 55 is used to slow down the flow rate of the downstream water flow. The fifth connector 58 is a mortise and tenon connector that matches the mortise and tenon connector of the third connector 35 in the spillway connection module 3 .

When the spillway connection module 3, the spillway deformation module 4, and the spillway assembly module 5 are connected, the bottom plate edge adopts a mutually matched inclined pressure surface structure, and a water stop rubber is arranged at the inclined pressure surface structure, so that the bottom plate of each module can be tightly spliced ​​and waterproof and leakproof.

[0035] Specifically, when a dam overflow situation occurs, the specific steps of constructing the spillway device of the present invention are as follows: a: First, assemble the water retaining plate assembly module 1 on the dam top to form a water retaining wall, set water-stop rubber strips at the connection of the water retaining plate assembly module 1, and use bolts to connect the water retaining plate assembly modules 1.

For steeper or soft slopes, anchors can be driven into the anchor holes to enhance the stability of the spillway assembly module 5 on the dam slope; f: Repeat steps d and e on multi-level bridleways and sloped corners.
