Technical Field

[0001] The present invention relates to the technical field of dam engineering, and specifically provides a bund device and a hydraulic fill dam. Background Art

[0002] A hydraulic fill dam is a kind of earth dam widely used in the construction of silt detention dams. It uses mechanical pumping or gravity flow diversion to divert water to the soil site on the mountain, washes the soil with water to form slurry, and the slurry flows along the mud channel to the filling pond at the dam site. After dewatering and consolidation, it becomes a dense dam body.

[0003] Often, it is necessary to surround the upstream and downstream with earth embankments to form bunds, and then fill the filling pond with slurry. The construction of the bund is mainly carried out by step-by-step layered ramming. First, the bottom bund is built to form the bottom filling pond, and loose soil is obtained to get a large amount of earthwork. By washing the soil with water to make mud and pouring the slurry into the bottom filling pond and consolidating it, when the daily settlement of the bottom filling pond meets the specification requirements, the upper bund is built.

[0004] The existing construction of bunds is mainly through manual ramming or piling up loose soil embankments.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "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, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] It should be noted that the first direction mentioned in the present invention is Figure 1 the direction in which the paper surface faces inward in

[0029] The existing hydraulic-fill dam is mainly constructed by manual ramming and building earth embankments with loose soil. Manual ramming is to layer and compact the soil and fill the cracks. The construction quality is good, but the construction time is long and the efficiency is low. Building earth embankments with loose soil is to directly pile up soil at the place where the embankment is to be built and compact it with an excavator or a tractor. This method has relatively high work efficiency, but the stability of the embankment is poor. However, the above two methods of building embankments also have the problems that the earth dam composed of soil embankments has poor stability, and if the drainage is not smooth during construction, it may cause the landslide of the dam body.

[0030] To solve the above problems in the prior art, please refer to Figures 1 to 3 , as shown in the figure, this embodiment provides a kind of embankment device, which includes a plurality of connecting bodies 10. Adjacent connecting bodies 10 are fixedly connected. The connecting body 10 includes a main body frame 101. A first fixing member 102 is provided at the bottom end of the main body frame 101. The first fixing member 102 is used to fixedly connect the main body frame 101 with the ground. An inclined baffle 20 is provided in the first direction of the main body frame 101. The upper part of the baffle 20 is fixedly connected with the main body frame 101. A second fixing member 201 is provided at the lower part of the baffle 20. The second fixing member 201 is used to fixedly connect the baffle 20 with the ground.

[0031] Through the above technical solution, a plurality of connectors 10 are fixedly connected, and an inclined baffle 20 is arranged on the connector 10 to form a bund that can be assembled conveniently and quickly. The combined method improves the construction speed of the hydraulic fill dam; the first fixing member 102 on a single connector 10 is fixedly connected to the ground, and the single connector 10 is fixed to the ground through the second fixing member 201 on the baffle 20, so that the combined bund is more stable.

[0032] In order to make the connector 10 have a higher strength, in this embodiment, the connector 10 and the baffle 20 are integrally cast by concrete. For example, the concrete can be integrally cast with C30 strength concrete. The main frame 101 in the connector 10 is 10m high, 1.5m wide, and 0.3m thick, and the baffle is 0.4m thick.

[0033] It should be noted that the integral casting of the above-mentioned connector 10 and the baffle 20 is illustrative. In other embodiments, other structures can also be adopted. Of course, the use of C30 strength concrete above is also illustrative, and other cement grades can also be adopted in other embodiments. For example, the connector 10 and the baffle 20 are cast separately, and then the connector 10 and the baffle 20 are fixed together through angle steel connectors.

[0034] Optionally, the main frame 101 is a rectangular frame. A plurality of first mounting holes 104 are provided on the vertical beams 103 of the rectangular frame, and a first fixing member 102 is provided on the bottom cross beam 105 of the rectangular frame. In this way, the setting of the rectangular frame facilitates the production, transportation and installation of the connector 10. The adjacent two connectors 10 are fixed together by bolts passing through the first mounting holes 104 in the corresponding adjacent two connectors 10, and the assembly is convenient.

[0035] In addition, the first fixing member 102 can include a plurality of pile nails and a plurality of anchor bolts. The anchor bolts are arranged in the middle of the bottom cross beam of the rectangular frame, and the pile nails are arranged on the side of the cross beam. In this way, the connector 10 can be preliminarily fixed through the setting of the pile nails, and through the setting of the anchor bolts, it can prevent the device from being washed away due to too fast filling speed. For example, the pile nails can be made of carbon steel, 1.5m long and 0.3m in diameter; the anchor bolts are 3m long and are quick-setting concrete screw anchor bolts. Through the quick-setting concrete screw anchor bolts, the integrity between the bund and the surrounding rock mass can be improved, and the strength of the hydraulic fill dam and the function of soil and water conservation can be improved.

[0036] Of course, it is illustrative that the first fixing member 102 includes pile nails and anchor bolts. In other embodiments, other structures may also be adopted. For example, the first fixing member 102 may only have anchor bolts. After the first connecting body is fixed during installation, first fix the second connecting body 10 and the first connecting body 10 by passing bolts through the corresponding first mounting holes 104 to fix the two connecting bodies 10 first, and then fix the second connecting body 10 with anchor bolts, so as to complete the assembly of two adjacent connecting bodies 10. And so on for the subsequent connecting bodies 10 until all the connecting bodies 10 are installed.

[0037] It should be noted that the second fixing member 201 has the same structure as the first fixing member 102. The second fixing member 201 also includes a plurality of pile nails and a plurality of anchor bolts. The pile nails provided on the baffle 20 can be used to preliminarily fix the baffle 20, and at the same time, the anchor bolts provided on the baffle 20 are mainly used to resist debris flow disasters, further improving the strength of the connecting body 10.

[0038] It can be understood that it is illustrative that the first fixing member 102 and the second fixing member 201 may include pile nails and anchor bolts. In other embodiments, other combinations may also be adopted. For example, the first fixing member 102 is an anchor bolt and the second fixing member 201 is a pile nail. In this way, the positioning and fixing of the connecting body 10 and the baffle 20 can also be achieved.

[0039] For the convenience of manufacturing and forming the baffle 20 and the main body frame 101, in this embodiment, the included angle between the baffle 20 and the vertical beam 103 of the main body frame 101 is an acute angle. For example, the included angle between the baffle 20 and the vertical beam of the main body frame is 45°.

[0040] In order to make the structure of the connecting body 10 more stable, slurry or concrete is injected into the space enclosed by the baffle 20 and the main body frame 101.

[0041] For the convenience of fixedly connecting two baffles 20 to each other, connecting plates 30 are respectively provided on both sides of the baffle 20. A plurality of second mounting holes 301 are provided on the connecting plates 30, and bolts are used to fixedly connect two adjacent baffles 20 through the second mounting holes 301. For example, the thickness of the connecting plate 30 is 0.2 m, there are 8 second mounting holes 301, the diameter is 0.15 m, and they are equally spaced on the connecting plate 30.

[0042] Of course, it is illustrative that the above-mentioned baffle 20 is fixedly connected through the connecting plate 30. In other embodiments, it may also be in other forms. For example, a convex portion is provided on one side of the baffle 20, and a concave groove is provided on the other side. The convex portions and the concave grooves of two adjacent baffles 20 are arranged oppositely. In this way, two adjacent baffles 20 can also be fixed together by the plugging form of the convex and the concave groove.

[0043] To further increase the connection strength between the baffle 20 and the connecting plate 30, the baffle 20 and the connecting plate 30 are integrally formed by casting concrete.

[0044] Of course, the baffle 20 can also be detachably connected to the connecting plate 30. For example, the connecting plate 30 can be separately cast and then fixed to the set positions on both sides of the baffle 20 by rivets.

[0045] On the other hand, this embodiment also provides a hydraulic-fill dam, including the above-mentioned dike device.

[0046] For example, dike devices are arranged simultaneously upstream and downstream, and then slurry is filled in the gap between the dike devices arranged upstream and downstream to form a dam body. In this way, a firm dam body is formed.

[0047] Of course, dike devices can also be arranged simultaneously upstream and downstream. At this time, the dike device is formed by casting concrete in the entire space enclosed by the baffle 20 and the main frame 101, and then slurry is filled in the gap between the upstream dike device and the downstream dike device to form a dam body. In this way, the dam body is made more firm.

[0048] Of course, the above way of arranging dike devices simultaneously upstream and downstream is illustrative, and other structures can also be adopted when building other hydraulic-fill dams. For example, only the dike device in the present disclosure is used upstream or downstream.

[0049] So far, the technical solutions of the present invention have been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
