Description

Technical Field

[0001] This utility model belongs to the technical field of construction equipment for river dams in water conservancy projects, and specifically relates to a material hopper for the simultaneous construction of foundation material and mortar material for panel dams. Background Technology

[0002] In the construction of concrete-faced rockfill dams, the slope of the foundation material is a critical construction part, and its quality directly affects the operational safety of the face and the dam body. Currently, commonly used slope stabilization methods mainly include sloping roller-compacted mortar slope stabilization, extruded concrete sidewall slope stabilization, and formwork slope stabilization.

[0003] The extrusion-based slope stabilization method involves constructing the extrusion-based sidewalls before dam filling. This technique relies heavily on concrete mixer trucks for transporting concrete, and to meet the trucking requirements, the concrete slump cannot be too low. This leads to slow sidewall forming speed, poor forming effect, high admixture consumption, and a large workload for post-construction defect handling. The formwork-based slope stabilization method still heavily relies on manual labor, has low mechanization, poor construction efficiency, and is easily affected by on-site interference. The roller-compacted mortar slope stabilization method refers to the technique of spreading mortar after the subbase material is filled, initially compacted, the slope is trimmed, and the slope is roller-compacted. Two types of equipment for the simultaneous construction of cushion material and mortar on the upstream slope of a rockfill dam with a repositioning mechanism and a detour mechanism can achieve simultaneous construction of cushion material and mortar. However, the detour mechanism requires four cushion material inlets, while the repositioning mechanism requires two. Conventional hopper structures cannot meet the feeding requirements of these equipment. Therefore, there is an urgent need to develop a cushion material hopper for the simultaneous construction of cushion material and mortar on the upstream slope of a rockfill dam with a concrete panel. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a material hopper for the synchronous construction of material cushion layer and mortar for panel dams. The I-shaped material hopper can be used for the synchronous construction of material cushion layer and mortar for the upstream slope of the turnaround type panel rockfill dam, and the L-shaped material hopper can be used for the synchronous construction of material cushion layer and mortar for the upstream slope of the reset type panel rockfill dam.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a hopper for the synchronous construction of cushion material and mortar material of a panel dam, including a hopper body. The cross-sectional shape of the hopper body is an I-shaped structure or an L-shaped structure. The lower part of the four corners of the I-shaped hopper body is processed with discharge ports. The four sets of discharge ports correspond to the cushion material forming chamber of the synchronous construction equipment for cushion material and mortar material of the upstream slope of the reversible panel rockfill dam. The lower part of the two arms of the L-shaped hopper body is processed with discharge ports. The two sets of discharge ports correspond to the cushion material forming chamber of the synchronous construction equipment for cushion material and mortar material of the upstream slope of the repositionable panel rockfill dam.

[0006] The I-shaped hopper body of this utility model includes a first rectangular trough and a second rectangular trough. A first inverted V-shaped plate is arranged in the first rectangular trough along the length direction, and a second inverted V-shaped plate is arranged in the second rectangular trough along the length direction. Two sets of symmetrical discharge ports are formed between the lower part of the first rectangular trough and the bottom slope of the first inverted V-shaped plate, and two sets of symmetrical discharge ports are formed between the lower part of the second rectangular trough and the bottom slope of the second inverted V-shaped plate.

[0007] The first rectangular trough and the second rectangular trough of this utility model have openings on opposite sides and are connected by a hopper connecting plate. A third inverted V-shaped plate is provided between the first rectangular trough and the second rectangular trough.

[0008] The L-shaped hopper body of this utility model includes a third rectangular trough and a fourth rectangular trough, which are connected. A first inclined plate is provided at the left end of the third rectangular trough and the fourth rectangular trough, and a connecting baffle is provided at the right end of the first inclined plate. The bottom of the connecting baffle is flush with the bottom of the third rectangular trough and the fourth rectangular trough. Both ends of the connecting baffle are connected to the side walls of the third rectangular trough and the fourth rectangular trough, respectively. A fourth inverted V-shaped plate is provided between the connecting baffle and the inner side wall of the right end of the fourth rectangular trough. A set of discharge ports is formed between the fourth inverted V-shaped plate and the rear side wall of the right end of the fourth rectangular trough. A second inclined plate is provided on the inner side of the right end of the third rectangular trough. The second inclined plate is connected to the connecting baffle, and a set of discharge ports is formed between the second inclined plate and the inner side wall of the right side of the third rectangular trough.

[0009] Because this utility model adopts an I-shaped or L-shaped structure for the body of the subgrade hopper, the lower part of the four corners of the I-shaped hopper body is processed with discharge ports, and the four sets of discharge ports correspond to the subgrade material forming chamber of the synchronous construction equipment for subgrade material and mortar material on the upstream slope of the reversible rockfill dam. The lower part of the two arms of the L-shaped hopper body is processed with discharge ports, and the two sets of discharge ports correspond to the subgrade material forming chamber of the synchronous construction equipment for subgrade material and mortar material on the upstream slope of the repositionable rockfill dam. Through the corresponding arrangement of two sets of discharge ports and two forming chambers, the 40cm thick subgrade material is laid in layers, and the layered laying effectively ensures that the laying is uniform and dense.

Detailed Implementation

The hopper body has an I-shaped cross-section, with discharge ports machined at the lower corners of each of its four sides. These four discharge ports correspond to the foundation material forming chambers of the simultaneous construction equipment. Specifically, the hopper body includes a first rectangular trough 1-1 and a second rectangular trough 1-3. The first rectangular trough 1-1 and the second rectangular trough 1-3 have openings on opposite sides and are connected by a hopper connecting plate 1-2. A first inverted V-shaped plate 1-4 is provided along the length of the first rectangular trough 1-1. A third inverted V-shaped plate 1-5 is provided between a rectangular material trough 1-1 and a second rectangular material trough 1-3. A second inverted V-shaped plate 1-6 is provided along the length direction inside the second rectangular material trough 1-3. A set of discharge ports is formed between the lower part of the first rectangular material trough 1-1 and the bottom of the slope of the first inverted V-shaped plate 1-4. A set of discharge ports is formed between the lower part of the second rectangular material trough 1-3 and the bottom of the slope of the second inverted V-shaped plate 1-6. In this embodiment, the two sets of discharge ports are symmetrically distributed on both sides of the frame of the equipment for synchronous construction of cushion material and mortar material on the upstream slope of the deflected rockfill dam. Due to the structure of the first inverted V-shaped plate 1-4, the second inverted V-shaped plate 1-6, and the third inverted V-shaped plate 1-5, the cushion material falls into the first and third chambers of the cushion material forming silo under the action of gravity through the discharge ports. Example 2

[0017] The cushion material hopper of the equipment for simultaneous construction of cushion material and mortar in the panel dam described in this embodiment is used for the simultaneous construction of cushion material and mortar on the upstream slope of a repositionable panel rockfill dam. Figure 3 , 4As shown, the hopper body includes a third rectangular trough 1-7 and a fourth rectangular trough 1-8, which are connected. A first inclined plate 1-9 is provided at the left end of each trough, and a connecting baffle 1-12 is provided at the right end of the first inclined plate 1-9. The bottom of the connecting baffle 1-12 is flush with the bottom of the third rectangular trough 1-7 and the fourth rectangular trough 1-8. Both ends of the connecting baffle 1-12 are connected to the side walls of the third rectangular trough 1-7 and the fourth rectangular trough 1-8. A fourth inverted V-shaped plate 1-10 is provided between the connecting baffle 1-12 and the inner side wall of the right end of the fourth rectangular trough 1-8. A second discharge port is formed between the fourth inverted V-shaped plate 1-10 and the rear side wall of the right end of the fourth rectangular trough 1-8. A second inclined plate 1-11 is provided on the inner side of the right end of the rectangular material trough 1-7. The second inclined plate 1-11 is connected to the connecting baffle 1-12. A first discharge port is formed between the second inclined plate 1-11 and the inner wall of the right side of the third rectangular material trough 1-7. The cushion material slides down along the first inclined plate 1-9 to the right end of the cushion material hopper under the action of gravity. Under the action of the third inverted V-shaped plate 1-10, it falls into the second discharge port and simultaneously falls into the first discharge port along the second inclined plate 1-10. In this embodiment, the first discharge port and the second discharge port are located on the same side of the frame of the synchronous construction equipment for cushion material and mortar material on the upstream slope of the reset panel rockfill dam. The length of the third rectangular material trough 1-7 is greater than the length of the fourth rectangular trough 1-8, ensuring that the first discharge port corresponds to the first compartment of the cushion material forming hopper and the second discharge port corresponds to the third compartment.
