Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a ditch construction system and a construction method. Background Art

[0002] In the ditch construction in fields such as municipal engineering and agriculture, the concrete pouring process is the core link determining the project quality and efficiency. Traditional ditch construction mostly adopts the methods of segmental formwork support pouring or precast component assembly. Among them, segmental formwork support relies on manual erection of formwork, pouring and vibrating section by section, and has problems such as long construction period, low formwork reuse rate, and uneven concrete density; while precast assembly faces defects such as high transportation cost, complex joint treatment, and difficulty in adapting to complex terrains.

[0003] In recent years, related technologies have improved the construction quality by improving the mold structure or optimizing the material ratio. For example, in the prior art CN202311207722 - a pouring device for producing resin concrete drainage ditches, the mixing of resin concrete and curing agent and the mold pouring and forming are realized through the cooperation of the pushing umbrella cone in the U - shaped empty pipe rack and the oscillation driver. The device can improve the standardization degree of precast drainage ditch components by matching the raw material ratio through the pressure - sensing adjustment mechanism.

[0004] However, the above - mentioned technologies still have the following technical limitations: on the one hand, this patent is only applicable to the batch production of standard components in the factory and cannot achieve on - site continuous pouring. Especially for long - distance ditches in the wild or non - standard cross - section projects, it is necessary to repeatedly transport and install precast components, resulting in low construction efficiency. On the other hand, the concrete anti - solidification ability is insufficient, relying on an external feeding system to input resin concrete and curing agent, lacking a dynamic stirring anti - block mechanism for the decrease in concrete fluidity during on - site pouring, which is easy to cause the blockage of the feeding hole or the interruption of pouring. Moreover, the device integration degree is low, and modules such as an oscillation driver and a pressure - sensing adjustment mechanism need to be independently configured, with a complex structure and high energy consumption, making it difficult to integrate with a mobile construction platform and restricting the flexibility of on - site construction.

[0005] Therefore, the present invention provides a ditch construction system and a construction method to solve one or more of the above problems. Summary of the Invention

[0039] Embodiment 1

[0040] Please refer toFigure 1 - Figure 2 , the present invention provides a technical solution, including: a construction table 2, two sets of outer ditch formworks 4 and one set of inner ditch formwork 5 are installed at the bottom of the construction table 2, and a "U"-shaped ditch pouring cavity is formed between the two sets of outer ditch formworks 4 and the inner ditch formwork 5. A feeding hole 7 communicating with the "U"-shaped pouring cavity is opened on the construction table 2. A two-way mixing assembly 6 is installed on the top of the construction table 2, and an oscillation knocking unit 39 is provided on the outer walls of the two sets of outer ditch formworks 4.

[0041] Preferably, walking wheels 3 are installed at the bottoms of both ends of the construction table 2, and two sets of avoidance grooves 8 are symmetrically opened on the construction table 2.

[0042] Preferably, the outer ditch formwork 4 and the inner ditch formwork 5 are detachably installed at the bottoms of the two sets of outer ditch formworks 4 and the inner ditch formwork 5, and need to be adjusted according to the actual size of the ditch.

[0043] The present invention also provides a ditch construction method for constructing through a ditch construction system. The construction method includes:

[0044] S1: Use an excavator to dig a construction ditch 1 at the location where construction is required, and then move the construction table 2 above the construction ditch 1 through the walking wheels 3;

[0045] S2: Install the two sets of outer ditch formworks 4 and one set of inner ditch formwork 5 at the bottom of the construction table 2 and inside the construction ditch 1;

[0046] S3: After injecting concrete into the mixing box 9, start the driving motor 10 to stir the concrete in the mixing box 9 to prevent it from solidifying;

[0047] S4: On the basis of S3, move the construction table 2 slowly along the construction ditch 1 through the walking wheels 3, and make the concrete in the mixing box 9 be injected into the "U"-shaped ditch pouring cavity formed between the two sets of outer ditch formworks 4 and the inner ditch formwork 5 through the feeding hole 7;

[0048] S5: On the basis of S4, the oscillation knocking unit 39 will synchronously strike the outer ditch formwork 4 to make the concrete more compact, improving the pouring quality.

[0049] The working principle and beneficial effects of the above technical solution are as follows: The construction trench 1 is dug at the location where construction is required by an excavator. Subsequently, the construction platform 2 is moved above the construction trench 1 through the walking wheels 3. Two sets of outer trench formworks 4 and one set of inner trench formwork 5 are installed at the bottom of the construction platform 2 and located within the construction trench 1. In order to ensure the construction effect and efficiency, the two sets of outer trench formworks 4 and one set of inner trench formwork 5 can be extended or shortened arbitrarily. Subsequently, concrete is injected into the two-way mixing assembly 6 by a concrete truck to prevent the concrete from solidifying during pouring. At this time, the construction platform 2 is moved slowly along the construction trench 1 through the walking wheels 3, and the concrete in the two-way mixing assembly 6 is injected between the two sets of outer trench formworks 4 and the inner trench formwork 5 to form a "U"-shaped trench pouring cavity. At the same time, the vibration knocking unit 39 will synchronously strike the outer trench formwork 4 to make the concrete more compact, thereby improving the pouring quality. After the first section of the trench is poured, the set of outer trench formwork 4 and the inner trench formwork 5 can be disassembled and moved to the position of the next section of the trench to be poured, thus realizing a reciprocating cycle construction, greatly improving the construction effect and efficiency.

[0050] Embodiment 2

[0051] On the basis of Embodiment 1, please refer to Figure 2 - Figure 4 , the two-way mixing assembly 6 includes: a mixing box body 9, the mixing box body 9 is fixedly arranged on the top of the construction platform 2, a driving motor 10 is fixedly arranged on the top of the mixing box body 9, and the output shaft of the driving motor 10 extends into the mixing box body 9 movably. A concrete feeding port is opened on the rear outer wall of the mixing box body 9.

[0052] Preferably, the fixed end of the main stirring sleeve 11 is fixedly connected to the output shaft of the driving motor 10, the auxiliary stirring rod 40 is slidably connected to the main stirring sleeve 11 up and down, the driving disk one 12 is fixedly sleeved on the outer wall of the main stirring sleeve 11, the driving disk two 13 is movably sleeved on the outer wall of the main stirring sleeve 11 through a bearing sleeve one 18, and the driving disk one 12 is located above the driving disk two 13.

[0053] Preferably, the driving disk one 12 and the driving disk two 13 are both provided with the same meshing tooth blocks one 15 on the side close to each other, the driving gear one 14 is installed between the driving disk one 12 and the driving disk two 13, and the driving gear one 14 meshes with the meshing tooth blocks one 15.

[0054] Preferably, two groups of surrounding stirring rods 19 are installed at the bottom of the second driving disc 13 through bearings, and a second driving gear 23 is fixedly sleeved at the bottom of the surrounding stirring rod 19. A first limiting and guiding groove 25 is formed on the construction table 2. A vertical guiding block is arranged at the bottom of the driving frame 22, and the driving frame 22 is slidably connected with the first limiting and guiding groove 25 through the guiding block at the bottom. Second engaging teeth 24 are symmetrically arranged on the inner wall of the driving frame 22. The second driving gear 23 is arranged in the driving frame 22 and meshes with the second engaging teeth 24.

[0055] Preferably, a number of groups of limiting rods 41 are fixedly arranged on the outer wall of the secondary stirring rod 40. A number of groups of third limiting and guiding grooves 42 are formed on the inner wall of the main stirring sleeve 11, and the limiting rods 41 are slidably connected with the third guiding grooves 42. A second bearing sleeve 20 is installed at the bottom of the secondary stirring rod 40. A hinge seat 43 is fixedly arranged at the top of one side of the driving frame 22. One end of the H-shaped connecting rod 21 is hinged with the second bearing sleeve 20, and the other end of the H-shaped connecting rod 21 is hinged with the hinge seat 43 at the top of the driving frame 22.

[0056] Preferably, the range of the up-and-down movement of the secondary stirring rod 40 needs to be smaller than the distance between two groups of stirring blades on the outer wall of the surrounding stirring rod 19.

[0057] Preferably, the rotation angle of the driving motor 10 each time needs to be less than 180 degrees.

[0058] The working principle and the beneficial effects of the above technical solution are as follows: During use, by starting the driving motor 10, the main stirring sleeve 11 is driven to rotate reciprocally, so as to drive the main stirring sleeve 11 and the secondary stirring rod 40 below to rotate, so as to initially stir the concrete in the mixing box 9. At the same time, the main stirring sleeve 11 synchronously drives the first driving disc 12 to rotate, and further, the first engaging teeth 15 at the bottom of the first driving disc 12 drive the first driving gear 14 to rotate. When the first driving gear 14 rotates, it first drives the first connecting rod 16 to rotate so as to provide power for the shock knocking unit 39. Secondly, the first engaging teeth 15 on the second driving disc 13 drive the first engaging teeth 15 to rotate in the opposite direction (i.e., in the opposite direction to the rotation direction of the first driving disc 12). At this time, the second driving disc 13 can drive the stirring rod sleeve 17 to rotate through the first bearing sleeve 18, and the rotation direction of the stirring rod sleeve 17 is opposite to that of the main stirring sleeve 11, so that the stirring blades of the stirring rod sleeve 17 and the main stirring sleeve 11 rotate synchronously in opposite directions, further enabling the concrete in the mixing box 9 to rub and collide with each other, thereby preventing it from coagulating.

[0059] Furthermore, while the second driving disk 13 rotates, it can drive the two sets of surrounding stirring rods 19 at its bottom to rotate around the stirring rod sleeve 17 as the central axis. And since the second driving gear 23 installed at its bottom is engaged in the driving frame 22, while the surrounding stirring rod 19 rotates around the stirring rod sleeve 17, the second driving gear 23 moves along the inside of the driving frame 22 and can push the driving frame 22 to slide along the first limiting guide groove 25. At this time, since the two sets of surrounding stirring rods 19 are installed at the bottom of the second driving disk 13 through bearings, when the surrounding stirring rod 19 rotates around the stirring rod sleeve 17, it will collide with the concrete in the mixing box 9, causing it to have a tendency of passive self-rotation. Coupled with the rotation of the second driving gear 23 due to the engagement with the second tooth block 24 in the driving frame 22, therefore, the surrounding stirring rod 19 will rotate around the stirring rod sleeve 17 while rotating, so as to fully stir the concrete in the mixing box 9 and prevent the concrete from solidifying during pouring.

[0060] Furthermore, one of the driving frames 22 is connected to the second bearing sleeve 20 at the bottom of the auxiliary stirring rod 40 through the H-shaped connecting rod 21. Therefore, when the driving frame 22 reciprocates along the first limiting guide groove 25, due to the arrangement of the limiting rod 41 on the outer wall of the auxiliary stirring rod 40, the H-shaped connecting rod 21 will pull the auxiliary stirring rod 40 to move up and down along the inner wall of the main stirring sleeve 11 through the second bearing sleeve 20, so that the auxiliary stirring rod 40 can move up and down within a small range while rotating, further avoiding the solidification of the concrete at the bottom of the mixing box 9. And when the driving frame 22 reciprocates along the bottom of the mixing box 9, it can push the accumulated concrete at the bottom to enter the "U"-shaped ditch pouring cavity between the two sets of ditch outer templates 4 and the ditch inner template 5 through the feeding hole 7, thus preventing the concrete from being blocked at the feeding hole 7.

[0061] It should be noted that the stirring blades on the outer walls of the stirring rod sleeve 17, the surrounding stirring rod 19, and the auxiliary stirring rod 40 are staggered respectively to prevent collision during rotation. And the range of the up and down movement of the auxiliary stirring rod 40 should be less than the distance between the two sets of stirring blades on the outer wall of the surrounding stirring rod 19. And the rotation angle of the driving motor 10 each time should be less than 180 degrees (that is, the rotation angles in both the clockwise and counterclockwise directions need to be less than 180 degrees, and it immediately reverses when reaching the preset angle) to avoid damage to the H-shaped connecting rod 21 and the driving frame 22.

[0062] Embodiment 3

[0063] On the basis of any one of Embodiments 1-2, please refer to Figure 5 - Figure 6, the oscillating knocking unit 39 includes: a first connecting rod 16, one end of the first connecting rod 16 is fixedly connected to the first driving gear 14, the other end of the first connecting rod 16 extends out of the construction table 2 movably and is fixedly connected to a first bevel gear 27, two sets of mounting plates 29 and two sets of limiting members 32 are fixedly arranged on the outer wall of the mixing box 9 from top to bottom in sequence, the third connecting rod 26 is connected to the two sets of mounting plates 29 through bearings, a second bevel gear 28 is fixedly sleeved on the top of the third connecting rod 26, a third driving disc 31 is fixedly sleeved on the bottom of the third connecting rod 26, and bumps 30 are fixedly arranged on the outer wall of the third driving disc 31, and the first bevel gear 27 meshes with the second bevel gear 28.

[0064] Preferably, a second limiting and guiding groove 37 is formed in one of the mounting plates 29, a supporting block 38 is movably arranged on the top of this set of mounting plates 29, and the width of the supporting block 38 is greater than the width of the second limiting and guiding groove 37. The top of the fourth connecting rod 34 passes through the second limiting and guiding groove 37 and is fixedly connected to the bottom of the supporting block 38. The bottom of the fourth connecting rod 34 movably passes through the limiting member 32 and the avoidance groove 8 and is arranged in parallel with the outer wall of the ditch outer formwork 4, and a plurality of rubber heads 36 are connected to the fourth connecting rod 34 through the rubber heads 36. A return spring 33 is arranged in the limiting member 32, one end of the return spring 33 is fixedly connected to the outer wall of the mixing box 9, and the other end of the return spring 33 is fixedly connected to the fourth connecting rod 34.

[0065] The working principle and its beneficial effects of the above technical solution are as follows: when the first driving gear 14 rotates, it simultaneously drives the first connecting rod 16 to rotate, so that the first bevel gear 27 drives the second bevel gear 28 to rotate, and then the third connecting rod 26 rotates. When the third driving disc 31 arranged at the bottom of the third connecting rod 26 rotates, the two bumps 30 on its outer wall will reciprocally push the fourth connecting rod 34 to move towards the direction close to the outer wall of the mixing box 9, and when the bumps 30 are no longer in contact with the fourth connecting rod 34, the return spring 33 can assist the fourth connecting rod 34 to reset. Through the above method, the fourth connecting rod 34 can realize reciprocating movement in the horizontal direction. Then, driven by the fifth connecting rod 35, the rubber heads 36 knock on the ditch outer formwork 4, so that the concrete in the formwork is more closely and evenly distributed, and the air bubbles are removed through vibration, avoiding the appearance of honeycombing or pockmarked phenomena, and ensuring the improvement of the concrete pouring quality.

[0066] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
