Description

[0003] For example, the assembled ditch with application number 202022024719.2 discloses a prefabricated sheet pile body and a ditch side plate, which are connected by a mortise and tenon joint during assembly. The installation and fixing method is simple, but it has two problems: on the one hand, there is no connection between adjacent units, which may cause the adjacent units to be separated or misaligned horizontally; on the other hand, the adjacent units cannot prevent misalignment in the vertical direction between them, especially when the soil at the bottom of the ditch slope collapses or is lost, the support for the ditch structure is inevitably lacking, especially when the lack of support occurs at the connection between adjacent units, misalignment is more likely to occur, causing unevenness, and a side of a unit may sink at the location lacking support, causing the entire unit to rotate, resulting in a gap between adjacent units, which not only causes unstable connection and unevenness, but also may cause water in the ditch structure to seep into the ditch slope through the gap, further exacerbating soil erosion.

[0063] The utility model discloses the specific embodiment of the utility model is as follows, and the technical scheme of the utility model is further described in connection with the drawings, but the utility model is not limited to these embodiments.

[0064] As Figures 1 to 4 As shown in the figure, a kind of assembled ditch, including ditch plate 10, and the vertical positioning mechanism 20 and horizontal positioning mechanism 30 of connecting two adjacent ditch plate 10, horizontal positioning mechanism 30 includes slot 31 and insert plate 32, a pair of slot 31 is symmetrically set in the side plate 1b of ditch plate 10, a pair of insert plate 32 is symmetrically set in the other side of side plate 1b of ditch plate 10, slot 31 is embedded in insert plate 32 and is horizontally connected a pair of ditch plate 10, vertical positioning mechanism 20 includes positioning block 21 and rotating block 22, the bottom plate 1a of ditch plate 10 is respectively equipped with let hole 100 relative to two sides, positioning block 21 is set on the side wall of let hole 100, rotating block 22 includes center shaft 221, lower plate 222 and upper plate 223, a pair of lower plate 222 between having interval 2220 is set in the lower part of center shaft 221, upper plate 223 is set in the upper end of center shaft 221, when a pair of ditch plate 10 is horizontally abutted, rotating block 22 is set in a pair of let hole 100, and positioning block 21 is embedded between lower plate 222 and upper plate 223.

[0065] In the utility model, when one to be assembled ditch plate 10 is combined with another ditch plate 10 positioned on the ditch slope, the to be assembled ditch plate 10 is placed into the ditch slope from top to bottom, so that the side walls of two ditch plates 10 abut, in this process, a pair of inserting plates 32 positioned on both sides of one ditch plate 10 are embedded into the insertion slots 31 on both sides of another ditch plate 10, and the insertion slots 31 and the inserting plates 32 can connect a pair of ditch plates 10 in the transverse direction; after a pair of ditch plates 10 abut each other, a pair of accommodation holes 100 are connected to form an installation cavity 100a, the installation cavity 100a has a pair of non-adjacent positioning blocks 21, the rotating block 22 is embedded into the installation cavity 100a, passes through the positioning block 21 through the interval 2220 between a pair of lower plates 222, so that the height position of the positioning block 21 is located in the area between the lower plate 222 and the upper plate 223, rotates the rotating block 22 (by rotating the upper plate 223) so that the positioning blocks 21 on the two ditch plates 10 are positioned between the lower plate 222 and the upper plate 223, and the lower plate 222 and the upper plate 223 limit the pair of positioning blocks 21 so that the pair of positioning blocks 21 always remain flush, thus keeping a pair of adjacent ditch plates 10 flush; further, to facilitate the rotation of the rotating block 22 relative to the positioning block 21 and limit the transverse movement of the rotating block 22 relative to the positioning block 21, the central shaft 221 is provided in a cylindrical structure, the cross sections of the lower plate 222 and the upper plate 223 are respectively fan-shaped and circular, and the side wall on the side of the positioning block 21 away from the accommodation hole 100 is provided with a profiled curved surface 212 capable of accommodating the outside of the central shaft 221; the utility model can prevent a pair of ditch plates 10 from separating or misaligning in the transverse direction through the transverse positioning mechanism 30, and can prevent a pair of ditch plates 10 from misaligning in the vertical direction through the vertical positioning mechanism 20, so that the connection between adjacent ditch plates 10 is still stable even if the bottom plate 1a of the ditch plate 10 is lost due to the collapse or soil erosion of the soil at the bottom of the ditch slope, and the connection stability between adjacent ditch plates 10 is ensured.

[0066] For the setting of the transverse positioning mechanism 30, in one embodiment, the insertion slot 31 is arranged on the ditch plate 10, and the hook portion (such as L-shaped structure) on one end of the inserting plate 32 extends out of the ditch plate 10 to realize that when the to be assembled ditch plate 10 is combined with another ditch plate 10 positioned on the ditch slope from top to bottom, the hook portion on the inserting plate 32 can be embedded into the insertion slot 31 to realize the connection and abutment between a pair of ditch plates 10. However, in the above embodiment, the sealing effect between the abutting pair of ditch plates 10 is not good, that is, the straight gap formed after the abutment between the two is easy to penetrate water into the ditch slope, therefore, in another embodiment, the Figure 1As shown, a pad 111 is provided on one side of the channel plate 10, and a cover plate 112 is provided on the other side. When a pair of channel plates 10 abut against each other, the cover plate 112 abuts against the upper end of the pad 111. The cover plate 112 and the pad 111 form a staggered gap, which provides a good sealing effect. Furthermore, as shown... Figure 5 As shown, a recess 1110 can be provided at the upper end of the pad 111, and a protrusion (not shown) matching the recess 1110 can be provided at the lower end of the cover plate 112. When the cover plate 112 abuts against the pad 111, the protrusion is embedded in the recess 1110, which can form a better sealing effect and improve the connection stability between the cover plate 112 and the pad 111. Based on the premise that the pad 111 and the cover plate 112 are provided on the trench plate 10, the insert plate 32 can be provided at the lower end of the cover plate 112 and the slot 31 can be provided on the pad 111. This can not only ensure the lateral connection of a pair of trench plates 10, but also improve the sealing between them, and facilitate the molding of the trench plate 10 structure (such as molding the trench plate 10 by molding, molding the pad 111 and the cover plate 112 on both sides of the trench plate 10 respectively, and molding the slot 31 and the insert plate 32 on the pad 111 and the cover plate 112 respectively).

[0067] like Figure 5 and Figure 7 As shown, in one embodiment related to the positioning block 21 and the rotating block 22, the positioning block 21 is provided with a positioning groove 211. The positioning groove 211 has an arc-shaped structure and opens upward. The lower end of the upper plate 223 is provided with a stop block 224 that matches the positioning groove 211. When the rotating block 22 is rotated so that the positioning block 21 is embedded between the lower plate 222 and the upper plate 223, a pair of stop blocks 224 on the rotating block 22 are respectively embedded in the positioning groove 211 on the positioning block 21 on the adjacent pair of channel plates 10. This can prevent the pair of channel plates 10 from laterally separating at this position. Therefore, in this embodiment, the lateral separation and vertical misalignment of the pair of channel plates 10 at this position can be achieved through the cooperation of the rotating block 22 and the positioning block 21. When the pair of channel plates 10 are connected by a vertical positioning mechanism 20 and two horizontal positioning mechanisms 30, the three-point connection can improve the connection stability.

[0068] Furthermore, the positioning groove 211 is provided with a locking block 2111, which has an arc surface structure, and the stop block 224 is provided with a locking groove 2241. When the stop block 224 is embedded in the positioning groove 211, the locking block 2111 is embedded in the locking groove 2241, which can ensure the installation stability of the rotating block 22 on the positioning block 21.

[0069] Continue as Figure 6As shown, in another embodiment related to the positioning block 21, the difference is that the clamping block 2111 is arranged in a vertical structure on the side wall of the positioning groove 211, and the matching clamping groove 2241 is also arranged in a vertical structure on the side wall of the stop block 224. In addition, the limiting plate 2112 is arranged at the rotating end of the stop block 224 in the positioning groove 211, which can avoid that the stop block 224 cannot be completely embedded in the positioning groove 211 after excessive rotation; the tightening structure can also be arranged at the rotating end of the stop block 224 in the positioning groove 211, and the tightening structure can be a tightening arc surface 2113 formed on the side wall of the positioning groove 211. When the stop block 224 rotates to the tightening arc surface 2113, the rotating block 22 can play a role of transverse pulling on the positioning block 21 due to the narrowing of the positioning groove 211, so that a pair of adjacent positioning blocks 21 (trench plate 10) are more closely attached.

[0070] Preferably, when the rotating block 22 is arranged in the mounting cavity 100a, the projections of the positioning block 21 and the lower plate 222 along the central axis of the central axis 221 coincide, which ensures the effectiveness of the lower plate 222 limiting the positioning block 21, and the upper end surface of the cylindrical upper plate 223 is flush with the side of the trench plate 10 away from the trench slope, which can realize the flatness of the trench plate 10 and the sealing of the mounting cavity 100a by the upper plate 223.

[0071] After the trench is installed in the trench slope, the ideal state is that the water flows in the trench, but it is inevitable that the water body also exists between the trench and the trench slope. In this case, if the liquid level in the trench is higher than that outside the trench, the stability of the trench in the trench slope can be ensured by the pressure difference, but if the liquid level in the trench is lower than that outside the trench, the floating state and instability of the trench may be caused. To solve the above problems, as shown, Figure 8 As shown, in one embodiment, the rotating block 22 is provided with a middle hole 220 penetrating the body thereof, and the anchor rod 25 for extending into the trench slope is arranged in the middle hole 220, so that the rotating block 22 and the trench plate 10 can be fixed in the trench slope. Although this method ensures the stability of the trench, the water body outside the trench always forms a large buoyancy on the trench, and long-term discharge can only make the water body penetrate into the trench slope, which may cause soil loosening or water and soil loss. Therefore, as shown, Figures 9 to 12As shown, in another embodiment, the rotating block 22 is also provided with a through hole 220 penetrating the body of the rotating block 22, preferably the through hole 220 penetrates the upper plate 223 and the central shaft 221, the through hole 220 is provided with the positioning member 23 and the plug 24, the positioning member 23 can be integrally formed with the rotating block 22, i.e. the positioning member 23 is fixed in the through hole 220, the body of the positioning member 23 and / or the body and the side wall of the through hole 220 are provided with the first through hole 2301 and the second through hole 2302, the plug 24 passes through the first through hole 2301 and forms the connecting rod 242 in the first through hole 2301, and the upper baffle 241 and the lower baffle 243 are formed at the upper end and the lower end of the connecting rod 242 respectively, the upper baffle 241 covers the through hole 220, and the lower baffle 243 does not cover the second through hole 2402, and the plug 24 is opened after moving upwards to open the through hole 220. Based on the above arrangement, when the liquid level in the trench is higher than the liquid level outside the trench, or there is no water body outside the trench, the water body in the trench can exert pressure on the upper baffle 241 to make the plug 24 block the through hole 220 to prevent the water body from flowing out of the trench; when the liquid level in the trench is lower than the liquid level outside the trench, the plug 24 is subjected to the upward buoyancy of the water body outside the trench which is greater than the downward pressure of the water body in the trench, so that the plug 24 (specifically the upper plate 241) is subjected to the buoyancy of the water body entering through the bottom of the through hole 220 and passing through the second through hole 2302, so that the upper plate 241 is lifted upward to open the through hole 220, allowing the water body outside the trench to enter the trench through the through hole 220, and since the lower baffle 243 is blocked by the first through hole 2031, the plug 24 cannot be separated from the through hole 220, the above water body flowing action at least makes the liquid levels inside and outside the trench the same, and the water body outside the trench synchronously diffuses to the trench slope and other factors finally make the liquid level in the trench higher than the liquid level outside the trench, so that the plug 24 is re-pressed to block the through hole 220, ensuring the stability of the trench.

[0072] Specifically, the positioning member 23 comprises a center ring 231 and a plurality of connecting rods 232 arranged on the outer wall of the center ring 231, the other ends of the plurality of connecting rods 232 are respectively fixedly connected with the side wall of the middle hole 220, the first through hole 2301 is formed on the center ring 231, the second through hole 2302 is formed between adjacent connecting rods 232, in an embodiment, the plug 24 can be an elastic member of an integral structure, one end of the plug 24 is extruded to pass through the first through hole 2301 and is deformed to form a connecting rod 242 located in the first through hole 2301 and a lower baffle 243 located below the first through hole 2301, then an upper baffle 241 is located above the first through hole 2301, the plug 24 is limited on the positioning member 23 by the upper baffle 241 and the lower baffle 243, when the upward floating force of the upper baffle 241 is greater than the pressure of the water body in the trench, the upward floating force of the water body acting on the lower end of the upper baffle 241 will make the upper baffle 241 stretch the connecting rod 242 upward to open the second through hole 2302, and then the water body will enter the trench, when the upward floating force of the upper baffle 241 is small, the connecting rod 242 disappears to make the upper baffle cover the second through hole 2302. Figure 11 As shown in the figure, the plug 24 is a hard member, which is assembled and formed, for example, the upper baffle 241 and the connecting rod 242 are an integral structure, the connecting rod 242 passes through the first through hole 2301, and the lower baffle 243 is installed at the lower end of the connecting rod 242, for example, a nut is screwed on the connecting rod, in this arrangement, in order to realize that the upper baffle 241 can move upward to open the second through hole, the length of the connecting rod 242 needs to be greater than the height of the first through hole 2301, since the connecting rod 242 is a hard member, the upper baffle 241 can only rely on its own gravity or the greater pressure of the water body in the trench to cover the second through hole 2302 again, therefore, in order to ensure that the upper baffle 241 can be reset smoothly, a spring 244 is sleeved on the connecting rod 242, the upper end and the lower end of the spring 244 are respectively in abutment with the positioning member 23 and the lower baffle 243, when the upper baffle 241 moves upward to open the second through hole 2302, the lower baffle 243 compresses the spring 244, when the upward floating force of the upper baffle 241 is small, the elastic recovery process of the spring 244 can drive the lower baffle 243 and the connecting rod 242 to move downward, so that the upper baffle 241 covers the second through hole 2303.

[0073] Preferably, the upper end surface of the upper plate 223 is provided with a recessed cavity 2231, and the upper baffle plate 241 is embedded in the recessed cavity 2231 to be flush with the upper end surface of the upper plate 223, which can ensure the flatness of the inner wall of the trench on the one hand, and can form a better sealing effect on the other hand; in addition, the side wall of the recessed cavity 2231 is provided with a first inclined abutting surface 223a, and the side wall of the upper baffle plate 241 is provided with a second matching inclined abutting surface 241a, the setting of the two inclined abutting surfaces can not only ensure the sealing effect, but also be beneficial to form a flared structure from bottom to top, which is conducive to the water body flowing into the trench after the plug 24 is lifted upward by the water level outside the trench when the water level outside the trench is higher than the water level inside the trench.

[0074] Preferably, a porous rib-like elastic body, such as a sponge, is arranged in the middle hole 220 below the positioning member 23 and the plug 24, which can prevent the soil in the slope of the trench from blocking the middle hole 220 upward.

[0075] As shown in Figure 4 and Figure 13 , in order to facilitate the rotation of the rotating block 22 in the installation cavity 100a, the upper end surface of the upper plate 223 is provided with a socket 2230 for the knob 50 to extend into to drive the upper plate 223 to rotate. For example, when the socket 2230 is a circular structure and has a plurality of sockets, the knob 50 includes a rotating plate 51, a plurality of insertion columns 52 and a holding portion 53, the holding portion 53 is arranged at the upper end of the rotating plate 51, and the plurality of insertion columns 52 in cylindrical structure are arranged at the lower end of the rotating plate 51, the insertion columns 52 are correspondingly embedded in the socket 2230, and the rotating block 22 is driven to rotate by rotating the holding portion 53 by hand; for another example, when the socket 2230 is a non-circular structure, the knob can be a straight plate structure, the lower end of the straight plate structure is embedded in the socket 2230, and the rotating block 22 is driven to rotate by rotating the knob.

[0076] For another example, as shown in Figure 3 , the trench plate 10 is an integral structure formed by molding, which includes a bottom plate 1a and side plates 1b located at opposite sides of the bottom plate 1a, and the side plates 1b include extension plates 1b' and fin plates 1b'', the extension plates 1b' are connected with the bottom plate 1a, the fin plates 1b'' are arranged at the upper end of the extension plates 1b', and the lateral positioning mechanism 30 is formed on the fin plates 1b'', which facilitates the molding of the insertion slot 31 and the insertion plate 32 during molding; similarly, the relief hole 100 and the positioning block 31 are also conveniently molded on the horizontal structure of the bottom plate 1a; in addition, a plurality of reinforcing ribs 1c can be formed on the side of the trench plate 10 close to the slope of the trench during the molding process, which improves the structural strength of the trench plate 10.

[0077] For another example, as shown in Figures 14 to 17As shown, in order to improve the ecological property of the trench plate 10 installed in the trench slope, to make the trench have better landscape effect when the liquid level is low, an ecological frame 40 can also be arranged in the trench, that is, a mounting hole 101 is arranged on the trench plate 10 and / or the rotating block 22, and the ecological frame 40 is connected to the trench plate 10 and located in the mounting hole 101.

[0078] As shown in Figure 14 and Figure 15 In one installation mode of the ecological frame 40, if the ecological frame 40 is a square structure, the mounting hole 101 is also a square structure, a first support plate 121 and a second support plate 122 are respectively arranged on the opposite inner walls of the mounting hole 101, a first limiting groove 411 and a second limiting groove 412 are respectively arranged on the opposite side walls of the ecological frame 40, and the first support plate 121 is embedded in the first limiting groove 411 and the second support plate 122 is embedded in the second limiting groove 412 to position the ecological frame 40 in the mounting hole 101. The premise of this installation mode is that the height position of the first support plate 121 in the mounting hole 101 is not lower than the height position of the second support plate 122, for example, when the mounting hole 101 is formed on the side plate 1b (the extension plate 1b''), the height position of the first support plate 121 is higher than the height position of the second support plate 122. The specific method of this installation mode is as follows: align the first limiting groove 411 with the first support plate 121, and move the ecological frame 40 upward to embed the first support plate 121 in the first limiting groove 411, when the first support plate 121 is completely embedded in the first limiting groove 411, adjust the ecological frame 40 to align the opening of the second limiting groove 412 with the second support plate 122, move the ecological frame 40 downward to at least partially embed the second support plate 122 in the second limiting groove 412, and because the depth of the first limiting groove 411 is greater than the length of the first support plate 121, although the ecological frame 40 moves downward by a certain distance, the first limiting groove 411 is still nested on the first support plate 121 at least near the outer side, so that the first support plate 121 and the second support plate 122 are respectively embedded in the first limiting groove 411 and the second limiting groove 412 to support and limit the ecological frame 40. Similarly, if it is necessary to take out the ecological frame 40 from the mounting hole 101, the ecological frame 40 can be first moved upward to disengage the second limiting groove 412 from the second support plate 122, then the ecological frame 40 is adjusted to disengage the second limiting groove 412 from the second support plate 122, and then the ecological frame 40 is moved downward to disengage the first limiting groove 411 from the first support plate 121, and finally the ecological frame 40 is taken out.

[0079] In this installation method, positioning plates 131 can be respectively set on the other two inner walls of the mounting hole 101, and first grooves 421 are respectively set on the lower part of the other two side walls of the ecological frame 40. A first baffle 422 is set on the lower part of one side of the first groove 421. The positioning plate 131 is embedded in the first groove 421 and moves with the ecological frame 40 so that the positioning plate 131 abuts against the upper end of the first baffle 422. Specifically, after the first support plate 121 is embedded in the first limiting groove 411, and when the opening of the second limiting groove 412 is adjusted to align with the second support plate 122, the first groove 421 moves downward and is sleeved on the positioning plate 131. During the process of the ecological frame 40 moving diagonally downward, the first baffle 422 moves to the upper end of the positioning plate 131 and abuts against the positioning plate 131. Therefore, the cooperation between the positioning plate 131, the first groove 421 and the first baffle 422 can make the ecological frame 40 more stable to be installed.

[0080] To avoid instability caused by the first baffle 422 only abutting against one side of the positioning plate 131, a first gap 420 is provided between the first baffle 422 and one side wall of the first groove 421. When the positioning plate 131 abuts against the inner wall of the first groove 421, the first baffle 422 and the positioning plate 131 can abut against each other at the middle position. It should be noted that when the ecological frame 40 is molded, a first clearance through hole 423 is provided on the ecological frame 40 above the first baffle 422. The formation of the first clearance through hole 423 during molding is due to the existence of a structure in the mold for forming the first baffle 422. That is, the existence of this structure in the mold makes it necessary for the ecological frame 40 to form the first clearance through hole 423.

[0081] like Figure 16 and Figure 17 As shown, in another installation method of the ecological frame 40, if the ecological frame 40 is a circular structure, the mounting hole 101 is also a circular structure. The mounting hole 101 is formed on the ditch plate 10. The lower part of the side wall of the ecological frame 40 is provided with a second groove 4101, and the lower part of one side of the second groove 4101 is provided with a second baffle 4102. The second baffle 4102 is set in the second groove 4101 to form a limiting groove 41. The support plate 12 on the inner wall of the mounting hole 101 is embedded in the second groove 4101 and abuts against the upper end of the second baffle 4102 by the rotation of the ecological frame 40. When the mounting hole 101 is formed on the side plate 1b (extension plate 1b"), the specific method of this installation is as follows: adjust the ecological frame 40 to be parallel to the side plate 1b, and align the positions of the second grooves 4101 without the second baffles 4102 with the pair of support plates 12 respectively. After the ecological frame 40 moves, the second grooves 4101 are fitted onto the support plates 12, and after the ecological frame 40 rotates, the second baffles 4102 are located at the lower end of the support plates 12, positioning the ecological frame 40 in the mounting hole 101.

[0082] The second gap 4100 is between the second baffle 4102 and the side wall of one side of the second groove 4101, when the support plate 12 abuts against the inner wall of the second groove 4102, the second baffle 4102 can abut against the middle position of the support plate 12 to keep stability; when the ecological frame 40 is molded, the second accommodation through hole 4103 is arranged above the second baffle 4102 on the ecological frame 40, and the structure for molding the second baffle 4102 in the mold makes the second accommodation through hole 4103 necessarily formed on the ecological frame 40.

[0083] In another installation mode of the ecological frame 40, the ecological frame 40 is a circular structure, the installation hole 101 is also a circular structure, and the structure in the installation hole 101 is also the same, but the installation hole 101 is not molded on the trench plate 10, but is molded on the rotating block 22 (the structure on the outer side of the rotating block 22 is unchanged), in this way, the rotating block 22 can serve as a connecting structure of a pair of trench plates 10 and also as a carrier of the ecological frame 40. It should be noted that, in order to match the size of the ecological frame 40, the size of the rotating block 22 and the size of the accommodation hole 100 on the trench plate 10 need to be adaptively adjusted in this embodiment.

[0084] For the ecological frame 40 described above, it can be only a frame structure with the through hole structure 400, the through hole structure 400 is used for plants on the trench slope to extend into the trench, and a porous elastic body (such as a sponge) can be arranged at the lower end of the frame structure by interference embedding or the like, the porous elastic body covers the through hole structure 400, which can allow branches and leaves of plants to pass through, but the (complicated) root system of the plants cannot pass through and leave the trench slope and the porous elastic body, so that the plants can be stably planted in the trench slope.

[0085] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
