Description

Technical Field

[0001] The utility model relates to the field of drainage ditches, in particular to an assembled drainage ditch. Background Art

[0002] Drainage ditches refer to ditches that divert water from side ditches, intercepting ditches, and low-lying areas near roadbeds, crops, and houses to outside of roadbeds, crops, and houses. Existing drainage ditches are mainly made by digging trenches, then building trench bodies in the trenches, and coating the surface with cement mortar. This on-site production method requires a large amount of work and is time-consuming and labor-intensive.

[0003] To solve the above problems, Chinese patent application number 2020212417539 discloses a prefabricated assembled drainage ditch, comprising a number of prefabricated ditch bodies connected in sequence, and a ditch cover plate covered on the top of the corresponding ditch body, wherein the ditch body has a guide groove along its length direction; one end of the ditch body in the length direction is concavely provided with a U-shaped slot around its end surface, and the other end thereof protrudes outwardly and is provided with a card block matching the shape of the slot; the adjacent ditch bodies are connected by the slot at the end of the ditch body and the card block for card engagement; it also includes a reinforcement mechanism; the reinforcement mechanism includes a hinge and a lock body, which are respectively located on the outer side surfaces of the ditch body at the connection of the two adjacent ditch bodies and fixed on the outer wall of the ditch body; one side of the hinge is fixed on the outer wall of the ditch body, and the other side is a lock buckle with a lock hole; when the two adjacent ditch bodies are spliced, the lock buckle on the hinge is hung on the lock body of the outer wall of the same side of the adjacent ditch body through the lock hole. Although the use of the above-mentioned prefabricated assembled drainage ditch can effectively improve efficiency, if it is directly applied to the crop field, the drainage ditch has a single function and can only be used for drainage in the flood season or as a ditch for releasing water in the dry season, and cannot store water when it rains. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide an assembled drainage ditch to solve the problem that the existing assembled drainage ditch has a single function and cannot store water when it rains.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An assembled drainage ditch includes a plurality of ditch body units connected end to end, a water-passing groove is provided in the middle of each ditch body unit, at least one water baffle is detachably installed on the inner wall of the water-passing groove of at least two ditch body units, the water baffle is sealedly connected to the inner wall of the water-passing groove, and a water reservoir is formed between two adjacent water baffles and the ditch body units connected thereto. In this way, after assembling a plurality of water baffles in the water-passing groove of each ditch body unit, a sealed water reservoir can be formed between two adjacent water baffles and the corresponding section of the water-passing groove, so that rainwater can be collected when it rains, which is convenient for pumping water into each water reservoir for irrigation later. When drainage is required, each water baffle can be taken out to connect the water-passing grooves of each ditch body unit to form a drainage ditch.

[0007] Furthermore, at least one soil organism penetration channel is provided at the lower end of each ditch unit along its width direction. Thus, after the soil organism penetration channel is provided at the lower end of each ditch unit, soil organisms such as earthworms and leeches in the soil layer can pass through the drainage ditch.

[0008] Furthermore, the groove body unit is assembled from a first groove body and a second groove body, and at least one slot for clamping a water baffle is provided on the inner wall of the water-passing groove of each of the first groove body and the second groove body, and a sealing rib is provided along the slot body direction. In this way, after the slot is provided, the water baffle can be inserted into the slot and fit tightly therewith. The sealing rib provided in the slot can increase the sealing between the water baffle and the slot.

[0009] Furthermore, the two end surfaces of the first ditch body and the second ditch body in the length direction are respectively provided with a convex edge and a butt joint connected in a tongue-and-groove manner; the lower ends of the two connecting ends of the first ditch body and the second ditch body are respectively provided with a convex block and an external connection groove connected in a tongue-and-groove manner; the convex edge and the butt joint are both arranged along the inner wall of the water-passing ditch. In this way, the end surfaces of the first ditch body and the second ditch body that are in contact with each other are connected through a tongue-and-groove structural connection, which can effectively ensure the sealing between the first ditch body and the second ditch body, and ensure that the water in the drainage ditch will not flow out through the gap between the contacting end surfaces.

[0010] Furthermore, the lower end of the connection side of the first groove body extends outward to form an extension portion, and the external groove is arranged on the extension portion; the lower end of the connection side of the second groove body is provided with a step surface, and the convex block is arranged on the step surface, corresponding to the external groove. In this way, the first groove body and the second groove body are also connected together by the mortise and tenon connection of the external grass and the convex block, and the connection structure is stable. The provided extension portion and the step surface can form a whole between the first groove body and the second groove body after being plugged and fixed with the convex block and the external groove, and there is no gap at the connection.

[0011] Furthermore, one of the side walls of the external groove body is an inclined surface inclined outward. In this way, after the outer side of the external groove body is set as an inclined surface, it is convenient for the protruding block to be quickly connected to the external groove under the guidance of the inclined surface when the first groove body is connected to the second groove body.

[0012] Furthermore, four rectangularly distributed tension through holes are provided on both sides of the water-passing grooves of the first groove body and the second groove body, and on the first groove body and the second groove body. The adjacent ends of the first groove body and the second groove body and the adjacent two groove body units are locked and fixed by a U-shaped threaded tie rod. After the two threaded rods of the U-shaped threaded tie rod pass through the two corresponding tension through holes on the first groove body and the second groove body respectively, they are matched with a locking nut to lock and fix the first groove body and the second groove body. In this way, on the basis of the tongue-and-groove connection, the first groove body and the second groove body are tension-connected by tension bolts, which can further improve the stability of the connection between the first groove body and the second groove body.

[0013] Further, an overflow hole is provided at the upper ends of the two side plates of the water-passing groove of the first ditch body and the second ditch body. In this way, after the overflow hole is provided, the water can overflow directly through the overflow hole when the water level is high.

[0014] Furthermore, at least one through hole is provided on each of the first trench body and the second trench body along the length direction thereof. In this way, the through hole provided can play a role in reducing weight. At the same time, when the ground is not stable enough, after a steel pipe is passed through the through holes on a plurality of trench body units, part of the trench body can be supported, so that it can adapt to various situations.

[0015] Furthermore, the water-passing grooves of the first ditch body and the second ditch body are both U-shaped, and a ditch cover plate with an end thereof is provided on the first ditch body and the second ditch body, and a plurality of small-sized biological passages are provided in each ditch cover plate at intervals, and the small-sized biological passages are provided along the width direction of the ditch body unit. In this way, the ditch cover plates provided can be stepped on and passed by people, and the small-sized biological passages provided can provide passages for small-sized creatures such as moles and frogs.

[0016] Furthermore, a lap joint groove is provided at the two lap joint ends of each trench cover plate, which matches with the upper end of the first trench body or the second trench body. In this way, the trench cover plate and the first trench body and the second trench body are lapped together through the groove, which is not easy to shift after assembly, and it is also convenient to disassemble and install the trench cover plate.

[0017] Furthermore, the first ditch body, the second ditch body and the ditch cover are prefabricated concrete blocks with a built-in steel mesh, so that the structural strength of the ditch body and the ditch cover is relatively high and the manufacturing cost is low.

[0025] Example 1

[0026] like Figure 1-Figure 4As shown, the present embodiment provides an assembled drainage ditch, comprising a plurality of ditch body units 1 connected end to end, wherein the ditch body unit 1 is assembled from a first ditch body 11 and a second ditch body 12, and a water-passing groove is provided in the middle of the first ditch body 11 and the second ditch body 12 of each ditch body unit 1; two water retaining plates 2 are detachably installed on the inner wall of the water-passing groove of each first ditch body 11 and the second ditch body 12 (a raised handle plate is provided on the side of the water retaining plate 2 for easy taking and installation), the water retaining plate 2 is sealedly connected to the inner wall of the water-passing groove, and a water reservoir is formed between two adjacent water retaining plates 2 and the ditch body unit 1 connected thereto; at the lower end of each first ditch body 11 and the second ditch body 12, at least one soil biological penetration channel 15 is provided along its width direction. In this way, after assembling a plurality of water retaining plates 2 in the water-passing grooves of each ditch body unit 1, a sealed water reservoir can be formed between two adjacent water retaining plates 2 and the corresponding sections of the water-passing grooves, so that rainwater can be collected when it rains, which is convenient for pumping water for irrigation in each water reservoir later. When drainage is required, each water retaining plate 2 can be taken out to connect the water-passing grooves of each ditch body unit 1 to form a drainage ditch. When assembling the water retaining plates 2, a water retaining plate 2 can be optionally set on part of the ditch body unit 1 as needed. After a soil biological penetration channel 15 is set at the lower end of each ditch body unit 1, soil organisms such as earthworms and leeches in the soil layer can pass through the drainage ditch.

[0027] Specifically, the installation of the water baffle 2 in this embodiment is achieved through the following structure: at least one slot 14 for clamping the water baffle 2 is provided on the inner wall of the water-passing groove of each first groove body 11 and the second groove body 12, and a sealing rib is provided along the groove body direction of the slot 14. In this way, after the slot 14 is provided, the water baffle 2 can be inserted into the slot 14 and fit tightly therewith. The sealing rib provided in the slot 14 can increase the sealing between the water baffle 2 and the slot 14.

[0028] In order to ensure the sealing and stability of the connection between the first groove body 11 and the second groove body 12 and each groove body unit 1, a convex edge 16 and a docking port 17 connected in a tongue-and-groove manner are respectively provided on the end surfaces of the two connecting ends in the length direction of the first groove body 11 and the second groove body 12; a convex block 19 and an external groove 18 connected in a tongue-and-groove manner are respectively provided at the lower ends of the two connecting ends of the first groove body 11 and the second groove body 12; the convex edge 16 and the docking port 17 are both arranged along the inner wall of the water-passing groove; four rectangularly distributed pulling through holes 13 are provided on both sides of the water-passing groove of the first groove body 11 and the second groove body 12, and the adjacent ends of the first groove body 11 and the second groove body 12 and the two adjacent groove body units 1 are locked and fixed by a U-shaped threaded tie rod 3, and the two threaded rods of the U-shaped threaded tie rod 3 respectively pass through the two corresponding pulling through holes 13 on the first groove body 11 and the second groove body 12, and then cooperate with a locking nut to lock and fix the first groove body 11 and the second groove body 12.

[0032] Furthermore, at least one through hole 10 is provided along the length direction of the first ditch body 11 and the second ditch body 12. In this way, the through hole 10 provided can reduce weight. At the same time, when the ground is not stable enough, after a steel pipe is passed through the through holes 10 on a plurality of ditch body units 1, part of the ditch body can be supported to adapt to various situations.

In this way, the trench cover plate 4 is overlapped with the first trench body 11 and the second trench body 12 through the groove, which is not easy to shift after assembly, and it is also convenient to disassemble and install the trench cover plate 4.

[0035] Furthermore, the first ditch body 11, the second ditch body 12 and the ditch cover 4 are prefabricated concrete blocks with a built-in steel mesh. In this way, the structural strength of the ditch body and the ditch cover 4 is relatively high, and the manufacturing cost is low.
