Description

Technical Field

[0001] The present application relates to the technical field of prefabricated panel rockfill dams, and in particular to a standardized concrete panel rockfill dam structure. Background Art

[0002] Rockfill dams, also known as local material dams, are characterized by the use of locally sourced materials. Constructed according to river valley topography, rockfill dams present complex and variable structural cross-sections. Furthermore, the dam's permeability stability and local material properties often require complex zoning of the dam structure, significantly increasing its construction time and cost. Concrete-faced rockfill dams utilize the excellent waterproofing properties of the face concrete to reduce the complexity of zoning within the dam structure to a certain extent, but they still have not completely overcome the limitations of zoning and filling within the dam structure. Currently, the concrete face of concrete-faced rockfill dams uses cast-in-place concrete, which significantly impacts the construction timeline. Furthermore, the large volume of face concrete requires a high maintenance environment, making it difficult to accurately control the panel molding quality. Molding defects can severely impact the waterproofing performance of the concrete face, directly impacting dam safety. To improve the construction quality and efficiency of concrete-faced rockfill dams, shorten the construction period, and reduce construction and operation and maintenance costs, a standardized concrete-faced rockfill dam structure is urgently needed that can overcome the limitations of zoning and filling within the dam structure, enable standardized, high-quality paving of the concrete face, and meet the requirements for high-efficiency, high-performance drainage and waterproofing of rockfill dams. Summary of the Invention

[0015] Furthermore, the standardized anti-filtration unit includes a connection module and an anti-filtration module, and the connection module is located at the four corners of the standardized anti-filtration unit;

[0016] The filtration unit connection system connects the standardized filtration units to each other through the connection module to form a standardized assembled filtration transition grid area, and is anchored to the grid gabion dam slope drainage body through the third anchoring system.

[0017] Furthermore, the third anchoring system is a pre-buried steel bar connected to the main reinforcement of the gabion gabion of the grid gabion dam slope drainage body, and is connected to the connection module.

[0018] Furthermore, the hexagonal standardized assembled panel group is a standardized self-waterproof concrete prefabricated structure, including 401-I standard type and 401-II diaphragm connection type;

[0019] The center of the 401-II diaphragm-connected regular hexagonal standardized panel has a connector pre-buried in the panel, and the exposed part of the connector is a block structure with the same material as the panel group partition membrane waterproofing system, a flat surface and a certain thickness.

[0050] In some embodiments, the third anchoring system is a pre-buried steel bar connected to the main reinforcement of the gabion gabion of the grid gabion dam slope drainage body and is connected to the connection module.

[0051] In some embodiments, the hexagonal standardized prefabricated panel group is a standardized self-waterproof concrete prefabricated structure, including a 401-I standard type and a 401-II diaphragm connection type; the center of the 401-II diaphragm connection type regular hexagonal standardized panel has a connector pre-embedded in the panel, and the exposed part of the connector is a block structure with the same material as the partition membrane waterproofing system of the panel group, a flat surface and a certain thickness.

[0052] In some embodiments, the panel group partition membrane waterproofing system covers a plurality of 401-II type hexagonal standardized assembled panels, and the 401-II type top surface waterproofing material is connected to the panel group partition membrane waterproofing system by hot melt welding.

[0053] In some embodiments, the panel group partition membrane waterproofing system divides the hexagonal standardized assembled panel group into several waterproof partitions in the form of partitioned laying, and adjacent waterproof partitions are connected to form a complete panel waterproofing system.

[0054] In some embodiments, the partition waterproof membrane seam distributed optical fiber monitoring system is arranged at the connection between adjacent waterproof partitions.

[0055] In some embodiments, the inter-panel expansion waterstop rods are embedded in the panel joints of the adjacent panel group partition membrane waterproofing system.

[0056] like Figures 1 to 8 As shown, the present application provides a standardized concrete panel rockfill dam structure, comprising a gridded gabion drainage system 1, a standardized rockfill body 2, a standardized prefabricated filter transition grid section 3, a group of hexagonal standardized prefabricated panels, and a zoned waterproofing system 4. The gridded gabion drainage system 1 forms a "dusting-pan-shaped" three-dimensional, efficient drainage system, enveloping the standardized rockfill body 2. The standardized filter transition grid section 3 is closely attached to the gridded gabion dam slope drainage body 104 of the gridded gabion drainage system 1. The group of hexagonal standardized prefabricated panels and the zoned waterproofing system 4 are laid on the standardized filter transition grid section 3. The bank slope and dam slope drainage body are connected to the surrounding area via an anchoring system. The standardized rockfill body 2 has no special requirements for the fill material of the dam body, other than stability, and there is no need to divide the dam body into zones. The standardized prefabricated filter transition grid section 3 is located upstream of the dam slope drainage body 104 and is anchored within the dam slope drainage body 104 via a third anchoring system 303.

[0057] The gabion drainage system 1's bank slope drainage leveling body 101 is formed by several layers of gabions stacked and connected closely to the surface of the bank slope leveling body, along the dam body and the direction of the river channel. It is connected to the surrounding mountain through a first anchoring system 102. The gabion bottom horizontal drainage body 103 is formed by several layers of individual gabions stacked and connected closely to the bedrock or dam foundation, along the direction of the river channel. It is located above the river channel leveling layer, below the standardized rockfill body 2 of the dam body, and downstream of the gabion dam slope drainage body 104. The gabion dam slope drainage body 104 is located between the standardized rockfill body 2 of the dam body and the standardized prefabricated filter transition grid area 3. It is composed of several layers of gabions stacked and connected closely to the upstream dam slope and anchored to the standardized rockfill body 2 via a second anchoring system 105.

[0058] In specific applications, the standard gabion unit size of the gabion system 1 can be 1.0m × 1.0m × 3.0m. In actual engineering design, the standard unit size should be flexibly adjusted based on on-site transportation conditions; in principle, the length should not be less than 3.0m. The main reinforcement diameter of the standard gabion unit of the gabion system 1 should not be less than the main reinforcement diameter of the hexagonal standardized prefabricated panel group 401. The connecting bars between the standard gabion units are welded, and the length and width of the welds meet the requirements of relevant specifications. More efficient and faster connection methods such as extruded sleeves can also be used between the standard gabion units, and the joint strength must meet the requirements of relevant specifications.

[0059] The first anchoring system 102 of the gridded gabion system consists of pre-buried anchor rods, the anchor heads of which are welded to the main reinforcement of the gabion. The joint strength must meet the requirements of relevant specifications. Preferably, the first anchoring system 102 of the gridded gabion system can be a prestressed anchor cable system. After the gridded gabion is installed in the corresponding position, the anchor cable is passed through the gridded gabion and the anchor head is fixed to the side of the gridded gabion closest to the dam body. Prestress is then applied and anchored, further enhancing the stability of the gridded gabion system.

[0060] The second anchoring system 105 of the gabion system consists of pre-buried anchor bars installed when the dam is filled to the appropriate position. These anchor bars penetrate deep into the gabion and are securely connected to at least two main gabion bars by welding. The joint strength must meet relevant regulatory requirements. The anchor bar must penetrate the dam by at least the length of a standard gabion unit, and its dimensions must be no less than 1.0m x 1.0m x 1.0m and no less than the maximum particle size of the dam filler. Preferably, after the pre-buried anchor bars of the second anchoring system 105 are installed, grouting is used to strengthen the connection between the anchor bar and the main dam structure, further enhancing the anchoring force.

[0061] The gabion drainage system 1's bank slope drainage leveling body 101, gabion bottom horizontal drainage body 103, and gabion dam slope drainage body 104 should be interconnected to form a "dustpan-shaped" three-dimensional drainage system. Standardized rockfill 2 does not divide the dam body into different rockfill zones based on the characteristics of the dam material, and there is no need to consider seepage effects when zoning the dam material.

[0062] Standardized filter unit 301 is a prefabricated, multi-layered bag-like structure of permeable geotextile, filled with connection modules 3011 and filter modules 3012. Connection modules 3011 are made of hardwood and are cube-shaped, approximately the same height as standardized filter unit 301. They are sealed at the four corners of the standardized filter unit and isolated from filter modules 3012. Connection modules 3011 can also be made of other materials with good water resistance, high strength, and good toughness, such as rubber or metal blocks.

[0063] The standardized filtration unit 301 can be prefabricated as a multi-layer structure, with filter media filled in different layers. The filter media particle size gradually increases along the water permeation direction, forming the filter module 3012, further enhancing the filtration effect of the standardized filtration unit. The four corners of the bagged multi-layer structure of the standardized filtration structure 301 serve as connecting modules 3011, providing sufficient strength and anchoring force. The filter module 3012 is formed by filling three to four layers of filter media, with the filter media particle size gradually increasing along the water permeation direction.

[0064] The filter unit connection system 302 is connected to the connection modules 3011 of the standardized filter units 301 in both the vertical and horizontal directions to form a standardized prefabricated filter transition grille area 3. The filter unit connection system 302 is made of galvanized steel strips, which are arranged vertically and horizontally along the connection modules 3011 and connected to the connection modules via rivets or self-tapping screws. Each connection module has at least one connection point with the galvanized steel strips. Adjacent standardized filter units 301 are connected vertically and horizontally via the galvanized steel strips to form a standardized filter transition grille. The standardized filter units 301 are connected to the pre-embedded steel bars of the main reinforcement of the gabion behind them via the galvanized steel strips.

[0065] like Figure 6 As shown, in this embodiment, based on the size of the rockfill dam panels, hexagonal standardized prefabricated panels 401 are laid on the dam surface to the greatest extent possible. In edge areas where the hexagonal standardized prefabricated panels cannot be fully laid, cast-in-place concrete is used to construct the panels. The panel group membrane waterproofing system 402 divides the hexagonal standardized prefabricated panel group 401 into three waterproof zones, each covered by several hexagonal standardized prefabricated panels. The panel group membrane waterproofing system is laid along the edges of the panel zones, with the membranes of adjacent zones overlapping.

[0066] Hexagonal standardized prefabricated panel cluster 401 is a self-waterproofing prefabricated concrete structure available in two types: the 401-I standard type and the 401-II membrane-connected type. The 401-I type is used for standardized panel assembly. The 401-II type panel has a pre-embedded spacer in the center made of the same material as the compartment membrane, which also strengthens the connection with the compartment membranes of the panel cluster. The panel cluster partitioned membrane waterproofing system 402 is a waterproof membrane that is laid in zones to divide the hexagonal standardized prefabricated panel cluster 401 into a series of panel waterproofing zones. Adjacent waterproofing zones are overlapped and connected to each other through heat-melt welding. The hexagonal standardized prefabricated panel cluster 401 covered by the panel cluster partitioned membrane waterproofing system 402 consists of several Type II hexagonal standardized prefabricated panels (401-II). The Type II hexagonal standardized prefabricated panel waterproofing membrane is connected to the panel cluster partitioned membrane waterproofing system 402.

[0067] Panel group partition membrane waterproofing system 402 is HDPE waterproofing membrane, at the joints of adjacent partitions, such as Figure 7As shown, the waterproofing membranes overlap and are connected using heat-melt welding. Within each waterproofing partition, several standard (401-I) panels are replaced with membrane-connected (401-II) panels. These 401-II panels are then heat-melted to the waterproofing system membrane to enhance adhesion. Self-adhesive waterproofing membranes can be used for the waterproofing system, ensuring a close fit with the panel surfaces within the partition for enhanced waterproofing. Double-seam heat-melt welding can be used to strengthen the joints of the panel partition waterproofing system.

[0068] A distributed optical fiber monitoring system 403 is buried under the heat-melt joints of adjacent waterproof partitions to ensure that at least one closed-loop monitoring network is formed within the panel group partition membrane waterproof system 402, and at least two optical fibers pass under each heat-melt joint to monitor the waterproof performance of the waterproof system in real time. Figure 7 As shown, in this example, expansion waterstop rods 404 are buried between the panels at the panel joints of the partitioned membrane waterproofing system 402 of adjacent panel groups. The expansion waterstop rods 404 between the panels are located in the middle of the panel joints, and their diameter is larger than the width of the membrane joints of the adjacent partitioned waterproofing system. The waterstop rods are pressed tightly by the panel's own gravity to form two lines of waterproofing at the joints, thereby enhancing the waterproof performance at the cross-panel joints.

[0069] The standardized concrete panel rockfill dam structure provided in the embodiment of the present application implements an assembled standardized design for the drainage system, filter transition zone, panel structure and waterproofing system of the dam body. The specifications of each component are unified and standardized, which is convenient for factory production. It can greatly facilitate on-site construction operations, improve construction efficiency and construction quality, and significantly reduce construction costs. The dustpan-shaped drainage system composed of gabion stone cages can quickly discharge the seepage water from the mountain and upstream to the downstream without passing through the main structure of the rockfill dam, thereby improving the stability of the dam body, reducing the filling construction and filling requirements for the main structure of the rockfill dam, and realizing the rapid filling of dam materials without partitioning. The hexagonal standardized assembled panels are combined with the partitioned waterproofing system, the distributed fiber optic monitoring system and the expansion water stop rod to build a complete and reliable waterproofing and monitoring system, which can significantly improve the waterproofing performance and safety of the dam body and provide great convenience for the maintenance and monitoring of the dam body.
