[0002] As a typical drainage structure, drainage ditches are widely used in road, slope and indoor drainage structures. The construction of existing drainage ditches mostly combines manual and mechanical operations, which occupy a lot of manpower and material resources during construction. Therefore, there are problems such as high investment, long construction period, and inconsistent operations. Summary of the Invention

[0003] The purpose of the invention is to provide a drainage ditch construction device that integrates drainage ditch excavation and slip form construction, which has the advantages of reducing resource investment, ensuring operation standards, and improving construction efficiency.

[0004] To achieve the above purpose, the invention provides a drainage ditch construction device, including:

[0005] A sliding mechanism, the sliding mechanism includes two guiding rods arranged at intervals, a first sliding component and a second sliding component respectively arranged at both ends of the guiding rods and fixedly connected to the two guiding rods, a fixing rod clamped between the two guiding rods and fixedly connected to the two guiding rods at both ends, and a pressing component installed on the fixing rod. The fixing rod is located between the first sliding component and the second sliding component. The pressing component includes a first hydraulic jack fixedly connected to the fixing rod and a pressing frame connected to the piston rod of the first hydraulic jack;

[0006] An excavation mechanism, the excavation mechanism is installed on the guiding rod and can slide along the guiding rod. The excavation mechanism is located in front of the pressing frame and is used for excavating the drainage ditch;

[0007] A slip form construction mechanism, the slip form construction mechanism is installed on the guiding rod and can slide along the guiding rod. The slip form construction mechanism is located behind the pressing frame and is used for pouring the bottom and side surfaces of the drainage ditch;

[0008] When the piston rod of the first hydraulic jack shortens and there is a gap between the pressing frame and the bottom of the drainage ditch, the first sliding assembly and the second sliding assembly can slide along the tracks on both sides of the drainage ditch and drive the pressing assembly to move, thereby changing the distance between the pressing frame and the excavation mechanism and the formwork construction mechanism. When the piston rod of the first hydraulic jack extends and the pressing frame presses tightly against the bottom of the drainage ditch, the first sliding assembly and the second sliding assembly are locked, and both the excavation mechanism and the formwork construction mechanism can slide along the guide rod, thereby changing the distance between the excavation mechanism and the pressing frame and the distance between the formwork construction mechanism and the pressing frame.

[0009] In a specific embodiment, the guide rod includes two oppositely arranged side walls and two oppositely arranged grooves formed by inward recesses from the outer surfaces of the lower ends of the two side walls. The excavation mechanism includes a plurality of first buckle portions that respectively catch the lower groove walls of the grooves at both ends and can slide along the guide rod, a housing fixedly connected to the plurality of first buckle portions, and an excavation assembly housed in the housing for excavating soil. The number of the first buckle portions provided on each guide rod is the same and is correspondingly arranged.

[0010] In a specific embodiment, the housing includes a bottom plate away from the sliding mechanism, two first side plates extending from both sides of the bottom plate towards the guide rod, a second side plate extending from the rear end of the bottom plate towards the guide rod, and a top plate oppositely arranged with the bottom plate. The bottom plate, the two first side plates, the second side plate, and the top plate jointly enclose the housing with an open front end. The excavation mechanism further includes a plurality of second hydraulic jacks installed on the second side plate. When the piston rod of the second hydraulic jack abuts against the pressing frame, the continuous extension of the piston rod of the second hydraulic jack can drive the excavation mechanism to move away from the pressing frame.

[0011] In a specific embodiment, the top plate is provided with an earth outlet. The excavation assembly includes a cutter head frame provided at the front end of the housing and fixedly connected to the housing, a plurality of cutter heads installed at one end of the cutter head frame away from the second side plate, a door plate spaced on the side of the cutter head frame facing the second side plate and fixedly connected to the housing, and a conveyor belt for transporting the soil cut by the cutter heads to the earth outlet. Among them, a notch is formed on the door plate by inward recess from the surface of the door plate away from the top plate towards the top plate. The conveyor belt includes a first conveyor belt for transporting the soil cut by the cutter heads to the notch, a second conveyor belt provided on the bottom wall and communicating with the notch, and a third conveyor belt with one end connected to the second conveyor belt and the other end connected to the earth outlet.

The first mounting rod includes a first cross bar perpendicular to and fixedly connected to the guide rod, and two first vertical bars perpendicularly bent and extended from both ends of the first cross bar. A first roller is provided at the lower end of each first vertical bar.

[0013] In a specific embodiment, the second sliding assembly includes a plurality of second mounting rods fixedly connected to the guide rod and a plurality of second rollers. The second mounting rod includes a second cross bar perpendicular to and fixedly connected to the guide rod, and two second vertical bars perpendicularly bent and extended from both ends of the second cross bar.

The number of the connecting members is the same as that of the second fastening parts.

[0015] In a specific embodiment, the connecting member includes a base provided on the second fastening part and a hydraulic cylinder fixedly connected to the base. The piston rod of the hydraulic cylinder is connected to the formwork machine.

[0016] The present invention also provides a construction method for a drainage ditch. The construction method uses the construction device described above for construction. The construction method includes multiple cycles of construction, and each cycle of construction includes:

[0017] When the construction device is in a state to be excavated, the excavation mechanism is located at a first position close to the pressing frame, and the formwork construction mechanism is located at a second position far from the pressing frame;

[0018] The piston rod of the first hydraulic jack extends to press the pressing frame against the bottom of the drainage ditch to lock the first sliding assembly and the second sliding assembly, and the excavation mechanism advances along the guide rod in a direction away from the pressing frame to excavate the drainage ditch;

[0019] When the excavation mechanism slides to a first target position, the excavation mechanism stops advancing, and the formwork construction mechanism advances along the guide rod in a direction close to the pressing frame to pour the bottom and side walls of the drainage ditch;

[0020] When the formwork construction mechanism slides to the second target position close to the pressing frame, the formwork construction mechanism stops advancing, and the piston rod of the first hydraulic jack shortens to set the pressing frame at an interval from the bottom of the drainage ditch, so as to unlock the first sliding assembly and the second sliding assembly;

[0021] The first sliding assembly and the second sliding assembly slide along the tracks on both sides of the drainage ditch and drive the pressing assembly to move until returning to the to-be-excavated state of the construction device.

[0022] The present invention also provides a construction method for a drainage ditch. The construction method uses the construction device described above for construction. The construction method includes multiple cycles of construction, and each cycle of construction includes:

[0023] When the construction device is in the to-be-excavated state, the excavation mechanism is located at the third position close to the pressing frame, and the formwork construction mechanism is located at the fourth position away from the pressing frame;

[0024] The piston rod of the first hydraulic jack extends to press the pressing frame against the bottom of the drainage ditch, so as to lock the first sliding assembly and the second sliding assembly. The excavation mechanism advances along the guide rod in the direction away from the pressing frame to excavate the drainage ditch. When the excavation mechanism slides to the third target position, the excavation mechanism stops advancing. At the same time, the formwork construction mechanism advances along the guide rod in the direction close to the pressing frame to pour the bottom and side walls of the drainage ditch. When the formwork construction mechanism slides to the fourth target position close to the pressing frame, the formwork construction mechanism stops advancing;

[0025] After both the excavation mechanism and the formwork construction mechanism stop working, the piston rod of the first hydraulic jack shortens to set the pressing frame at an interval from the bottom of the drainage ditch, so as to unlock the first sliding assembly and the second sliding assembly;

[0026] The first sliding assembly and the second sliding assembly slide along the tracks on both sides of the drainage ditch and drive the pressing assembly to move until returning to the to-be-excavated state of the construction device.

[0027] The beneficial effects of the present invention at least include:

[0028] 1. The drainage ditch construction device provided by the present invention includes a sliding mechanism that can slide along the tracks on both sides of the drainage ditch, an excavation mechanism for excavating the drainage ditch, and a slip form construction mechanism for pouring the drainage ditch. The excavation mechanism and the slip form construction mechanism are both connected to the sliding mechanism and can move forward relative to the sliding mechanism. In this way, the integrated autonomous excavation and pouring of the drainage ditch are realized, reducing the input of human and material resources during the construction of the drainage ditch project. At the same time, the standardization of the drainage ditch operation is ensured, and it has the advantage of high construction efficiency.

[0029] 2. The pressing frame of the construction device is connected to the guide rod through a first hydraulic jack. When the piston rod of the first hydraulic jack extends and the pressing frame is in close contact with the bottom of the drainage ditch, the first sliding component and the second sliding component are locked. At this time, first, the excavation mechanism can complete the excavation of the trench with the designed dimensions according to the trench excavation requirements. The soil is transported to the outside of the construction device through the cutting of the cutter head and the transportation of the conveyor belt, and the trench excavation device is pushed forward along the I-shaped track by the second hydraulic jack for excavation. Then, the slip form construction mechanism can slide forward along the guide rod for construction. After the construction of one cycle is completed, the piston rod of the first hydraulic jack shortens, causing the pressing frame to be spaced from the bottom of the drainage ditch, and the first sliding component and the second sliding component are released from self-locking. The sliding mechanism moves forward along the tracks laid on both sides of the drainage ditch to the next position, and then the construction of the next cycle is started. The present invention connects the excavation mechanism and the slip form construction mechanism through the guide rod and provides the sliding tracks for the excavation mechanism and the slip form construction mechanism, and can complete the construction of the drainage ditch through multiple cycles of construction, which can reduce the construction cost of the drainage ditch.

[0030] In addition to the purposes, features, and advantages described above, the present invention has other purposes, features, and advantages. The following will refer to the drawings for a more detailed description of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be defined and covered by the claims in various different embodiments.

[0041] Please refer to Figures 1 to 7 , the present invention provides a drainage ditch construction device 100. This construction device 100 realizes the integration of autonomous excavation and pouring of the drainage ditch, reduces the input of manpower and material resources during the construction of the drainage ditch project, and at the same time ensures the standardization of the drainage ditch operation, having the advantage of high construction efficiency.

[0042] The drainage ditch construction device 100 includes a sliding mechanism 10 capable of sliding along the tracks on both sides of the drainage ditch, an excavation mechanism 20 for excavating the drainage ditch, and a slip form construction mechanism 30 for pouring the drainage ditch. The excavation mechanism 20 and the slip form construction mechanism 30 are both connected to the sliding mechanism 10 and can move forward relative to the sliding mechanism 10.

[0043] The sliding mechanism 10 includes two guiding rods 11 arranged at intervals, a first sliding component 12 arranged at the front end of the guiding rods 11 and fixedly connected to the two guiding rods 11, a second sliding component 13 arranged at the rear end of the guiding rods 11 and fixedly connected to the two guiding rods 11, at least one fixing rod 14 clamped between the two guiding rods 11 and fixedly connected to the two guiding rods 11 at both ends, and a pressing component 15 installed at the lower end of the fixing rod 14.

[0044] In this embodiment, the front end and the rear end of the guiding rod 11 are defined relative to the advancing direction of the construction device. That is, if the construction device advances to the left, then the front end of the guiding rod refers to the left end of the guiding rod, and the rear end of the guiding rod refers to the right end of the guiding rod; if the construction device advances to the right, then the front end of the guiding rod refers to the right end of the guiding rod, and the rear end of the guiding rod refers to the left end of the guiding rod. In this embodiment, the front end of the guiding rod 11 is Figure 1On the right side shown, the rear end of the guide rod 11 refers to Figure 1 the left side shown.

[0045] In this embodiment, the guide rod 11 is a square rod structure, which includes two opposite side walls 111 and two opposite grooves 112 formed by inward indentation from the outer surfaces of the lower ends of the two side walls 111. The two grooves 112 combine to form a "work" - shaped groove.

[0046] In this embodiment, the extending direction of the guide rod 11 is the same as the extending direction of the groove 112.

[0047] Please refer to Figure 7 , the first sliding assembly 12 includes a plurality of first mounting rods 121 fixedly connected to the guide rod 11 and a plurality of first rollers 122. The first mounting rod 121 includes a first cross - bar 1211 perpendicular to and fixedly connected to the guide rod 11 and two first vertical rods 1212 perpendicularly bent and extended from both ends of the first cross - bar 1211. A first roller 122 is provided at the lower end of each first vertical rod 1212.

[0048] In this embodiment, the first sliding assembly 12 is fixedly connected to the upper end of the guide rod 11. It can be understood that an installation groove is formed by inward indentation on the upper surface of the guide rod 11. The first cross - bar 1211 of the first sliding assembly 12 is embedded in this installation groove and fixedly connected to the guide rod 11. The depth of this installation groove is less than the thickness of the guide rod 11, and the sum of the depth of the installation groove and the width of the groove is less than the thickness of the guide rod 11, that is, the installation groove does not sink to the bottom of the groove.

[0049] In this embodiment, the number of the first mounting rods 121 is three. Correspondingly, the number of the first rollers 122 is six, and each first mounting rod 121 is correspondingly installed with two first rollers 122.

[0050] The second sliding assembly 13 includes a plurality of second mounting rods 131 fixedly connected to the guide rod 11 and a plurality of second rollers 132. The second mounting rod 131 includes a second cross - bar 1311 perpendicular to and fixedly connected to the guide rod 11 and two second vertical rods 1312 perpendicularly bent and extended from both ends of the second cross - bar 1311. A second roller 132 is provided at the lower end of each second vertical rod 1312.

[0051] In this embodiment, the second sliding assembly 13 is fixedly connected to the upper end of the guide rod 11. It can be understood that an installation groove is formed by inward depression on the upper surface of the guide rod 11. The second cross bar 1311 of the second sliding assembly 13 is embedded in this installation groove and fixedly connected to the guide rod 11. The depth of this installation groove is less than the thickness of the guide rod 11, and the sum of the depth of the installation groove and the width of the groove is less than the thickness of the guide rod 11, that is, the installation groove does not sink to the bottom of the groove.

[0052] In this embodiment, the number of the second installation rods 131 is two. Correspondingly, the number of the second rollers 132 is four, and each second installation rod 131 is correspondingly installed with two second rollers 132.

[0053] In this embodiment, the number of the fixed rods 14 is two, and both of the two fixed rods 14 are arranged perpendicular to the guide rod 11.

[0054] The pressing assembly 15 includes a plurality of first hydraulic jacks 151 fixedly connected to the fixed rod 14, a pressing frame 152 connected to the telescopic rods of the plurality of first hydraulic jacks 151, and a plurality of positioning discs 153 installed on the side of the pressing frame 152 facing the excavation assembly 20.

[0055] In this embodiment, the first hydraulic jack 151 is used to change the distance between the pressing frame 152 and the bottom of the drainage ditch to lock or unlock the first sliding assembly 12 and the second sliding assembly 13. Specifically, when the first hydraulic jack 151 extends, the pressing frame 152 is in close contact with the bottom of the drainage ditch. At this time, the first sliding assembly 12 and the second sliding assembly 13 are in a locked state and cannot move; when the first hydraulic jack 151 shortens, the pressing frame 152 is spaced from the bottom of the drainage ditch. At this time, the first sliding assembly 12 and the second sliding assembly 13 are in an unlocked state, and the first rollers 122 of the first sliding assembly 12 and the second rollers 132 of the second sliding assembly 13 can move along the tracks on both sides of the drainage ditch. It can be understood that the construction device further includes a driving mechanism for driving the first sliding assembly 12 and the second sliding assembly 13 to roll. This driving mechanism is a power device in the prior art that can drive the first sliding assembly 12 and the second sliding assembly 13. The selection of this power device and the connection between this power device and the first sliding assembly and the second sliding assembly do not belong to the content of the present invention.

[0056] In other embodiments, the first hydraulic jack may also be a hydraulic cylinder, or other telescopic driving devices.

[0057] In this embodiment, the sliding mechanism 10 may further include a self-locking structure for assisting in locking the first roller and the second roller.

[0058] In this embodiment, the pressing frame 152 is a solid structure or a hollow frame structure, which is not limited in the present invention. The outer shape of the frame of the pressing frame 152 is the same as the shape of the drainage ditch.

[0059] In this embodiment, the number of the positioning disks 153 is eight. The side of the pressing frame 152 facing the excavation mechanism 20 is an isosceles trapezoid with a longer upper base and a shorter lower base, and two positioning disks 153 are arranged on each side.

[0060] Preferably, the sliding mechanism 10 further includes a first mounting seat 16 arranged on the fixed rod 14, and the first mounting seat 16 is used for mounting the pressing assembly 15.

[0061] In this embodiment, the number of the first mounting seats 16 is four. Two of the first mounting seats 16 are mounted on each fixed rod 14, and the two first mounting seats 16 are symmetrically arranged about the central axis of the fixed rod 14.

[0062] Correspondingly, the number of the first hydraulic jacks 151 is also four. One of the first hydraulic jacks 151 is fixed to the lower end of each first mounting seat 16, and the pressing frame 152 is mounted on the two fixed rods 14 through the four first hydraulic jacks 151. With this arrangement, the pressing frame 152 can be evenly stressed when being pressed, so as to better lock and unlock the first sliding component and the second sliding component.

[0063] Please refer to Figure 5 and Figure 6 , the excavation mechanism 20 is mounted on the guide rod 11 and can slide along the guide rod 11. During the forward sliding process of the excavation mechanism 20, the work of cutting soil and transporting soil is completed to form a drainage ditch.

[0064] The excavation mechanism 20 includes a plurality of first fastening portions 21 whose two ends respectively catch the lower groove walls of the grooves 112 and can slide along the guide rod 11, a housing 22 fixedly connected to the plurality of first fastening portions 21, an excavation assembly 23 housed in the housing 22 for excavating soil, and a plurality of second hydraulic jacks 24 mounted on one end of the housing 22 facing the pressing frame 152.

[0065] In this embodiment, the number of the first buckle portions 21 is six, with three of the first buckle portions 21 respectively provided on each of the guide rods 11, and the three first buckle portions on one guide rod 11 are arranged corresponding to the three first buckle portions 21 on the other guide rod 11. The corresponding arrangement here can be understood as that two first buckle portions 21 arranged correspondingly on the two guide rods are symmetrical about the axis of symmetry of the two guide rods.

[0066] In this embodiment, the first buckle portion 21 includes a buckle main body portion arranged parallel to the guide rod, two buckle extension portions vertically bent and extended from both ends of the buckle main body portion, and claws vertically bent and extended from the two buckle extension portions respectively towards the central axis direction of the buckle main body portion. The buckle main body portion, the two buckle extension portions and the two claws are connected to enclose two symmetrically arranged U-shaped openings. The buckle main body portion of the first buckle portion 21 abuts against the lower surface of the guide rod 11, and the lower side walls of the two grooves 112 are clamped in the two U-shaped openings.

[0067] Preferably, the excavation mechanism 20 further includes a second mounting seat 25 connected to the buckle main body portion of the first buckle portion 21, and a connecting column 26 with one end connected to the second mounting seat 25 and the other end connected to the housing 22. The housing 22 is fixed on the first buckle portion 21 through the second mounting seat 25 and the connecting column 26, so that when the first buckle portion 21 slides along the groove 112, the housing can slide together.

[0068] Correspondingly, the number of the second mounting seats 25 and the number of the connecting columns 26 are both the same as the number of the first buckle portions 21.

[0069] The housing 22 includes a bottom plate 221 away from the guide rod 11, two first side plates 222 extending from both sides of the bottom plate 221 towards the guide rod 11, a second side plate 223 extending from the rear end of the bottom plate 221 towards the guide rod 11, and a top plate 224 arranged opposite to the bottom plate 221. The bottom plate 221, the two first side plates 222, the second side plate 223 and the top plate 224 jointly enclose the housing 22 with an open front end.

[0070] An earth outlet 2241 is formed on the top plate 224, and the soil conveyed by the excavation assembly 23 is sent out from the earth outlet and then transported by other equipment.

[0071] The earth outlet 2241 is located at one end of the top plate 224 close to the pressing frame 152.

[0072] The shape of the housing 22 is the same as that of the drainage ditch. In this embodiment, the longitudinal section of the housing 22 is an isosceles trapezoid with a longer upper base and a shorter lower base.

[0073] Preferably, the front end of the bottom plate 221 is provided with a serrated structure to facilitate the cutting component 23 to cut into the soil mass.

[0074] The excavation assembly 23 includes a cutter head frame 231 disposed at one end of the housing 22 away from the pressing frame 152 and fixedly connected to the housing 22, a plurality of cutter heads 232 mounted at one end of the cutter head frame 231 away from the second side plate 223, a plurality of door panels 233 disposed at intervals on the side of the cutter head frame 231 facing the second side plate 223 and fixedly connected to the housing 22, and a conveyor belt 234 for transporting the soil cut by the cutter heads 232 to the soil outlet.

[0075] In this embodiment, the cutter head frame 231 is formed by cross-connecting a plurality of horizontally arranged rods and a plurality of vertically arranged rods to form a frame structure. The present invention does not specifically limit the structure of the cutter head frame 231, and it only needs to be able to stably mount the cutter heads 232.

[0076] The cutter heads 232 are used for cutting soil to form a drainage ditch, and the soil cut by the cutter heads 232 is output through the conveyor belt 234.

[0077] In this embodiment, the cutter heads 232 are at a preset distance from the front end of the bottom plate 221. In this way, by cutting into the soil mass through the serrated structure at the front end of the bottom plate 221, after the soil mass enters the housing, the cutter heads can then cut the soil mass, which can reduce the disturbance to the surrounding soil mass.

[0078] A notch 2331 is formed on the door panel 233 by being recessed from the surface of the door panel 233 away from the top plate 224 towards the top plate 224. The height of the soil mass transported from one side of the door panel 233 to the other side is restricted through this notch to ensure the normal operation of the conveyor belt 234.

[0079] Preferably, the excavation assembly 23 further includes a soil retaining plate 235 disposed obliquely outwards, so that the soil mass is more concentrated on the right side of the notch, which is convenient for transportation. The right side of the notch is based on Figure 5 the orientation shown.

[0080] The conveyor belt 234 includes a first conveyor belt 2341 for transporting the soil cut by the cutter heads 232 to the notch 2331, a second conveyor belt 2342 disposed on the bottom plate 221 and communicating with the notch 2331, and a third conveyor belt 2343 with one end connected to the second conveyor belt 2342 and the other end communicating with the soil outlet 2241.

[0081] In this embodiment, the excavation assembly 23 further includes a cutter head rotation power system for driving the rotation of the cutter head 232 and a driving mechanism for driving the conveyor belt 234. The cutter head rotation power system and the driving mechanism for the conveyor belt are prior arts and do not belong to the improved part of the present invention. Those skilled in the art can make selections based on conventional technical means.

[0082] The second hydraulic jack 24 is used to drive the excavation assembly 23 to slide along the guide rod 11. Specifically, when the housing 22 is disposed adjacent to the pressing frame 152, the piston rod of the second hydraulic jack 24 extends and abuts against the positioning disk 153 of the pressing frame 152. Then, the piston rod of the second hydraulic jack 24 continues to extend. Since the position of the pressing frame 152 is locked, the first latching portion 21 slides forward along the guide rod 11 under the reverse force generated by the pressing frame 152 when the second hydraulic jack 24 abuts against the pressing frame 152, and drives the housing 22 to move forward. During the forward movement of the housing 22, the cutter head cuts the soil mass, and the cut soil blocks fall onto the conveyor belt 234 and are conveyed by the conveyor belt 234 to the soil outlet 2241. When the excavation mechanism 20 moves to the extreme position at the front end of the guide rod 11, the second hydraulic jack 24 stops extending and retracts.

[0083] In this embodiment, the number of the second hydraulic jacks 24 is eight, which are evenly arranged to ensure the smooth forward movement of the excavation assembly 23.

[0084] The second hydraulic jack 24 has a corresponding relationship with the position of the positioning disk 153. The setting position of the positioning disk 153 has been described above, and the position of the second hydraulic jack 24 will not be elaborated here.

[0085] The formwork construction mechanism 30 includes a formwork machine 31, a plurality of second latching portions 32 that respectively clamp the lower groove walls of the grooves 112 at both ends and can slide along the guide rod, and a plurality of connecting members 33 with one end connected to the formwork machine 31 and the other end connected to the second latching portions. The number of the connecting members 33 is the same as the number of the second latching portions 32.

[0086] In this embodiment, the formwork machine 31 is a formwork machine in the prior art, including a vibrator, a hydraulic device, etc. The structure of the formwork machine 31 is not within the protection scope of the present invention.

[0087] In this embodiment, the number of the second buckle parts 32 is four. Two of the second buckle parts 32 are installed on each guiding rod 11, and the two second buckle parts on one guiding rod 11 are arranged corresponding to the two second buckle parts 32 on the other guiding rod 11. The corresponding arrangement here can be understood as that the two second buckle parts arranged correspondingly on the two guiding rods are symmetrical about the axis of symmetry of the two guiding rods.

[0088] In this embodiment, the structure of the second buckle part 32 is exactly the same as that of the first buckle part 21. It can be understood that the second buckle part 32 also includes a buckle main body part arranged parallel to the guiding rod, two buckle extension parts vertically bent and extended from both ends of the buckle main body part, and claw fingers vertically bent and extended from the two buckle extension parts towards the central axis direction of the buckle main body part. The buckle main body part, the two buckle extension parts and the two claw fingers are connected to enclose two symmetrically arranged U-shaped openings. The buckle main body part of the second buckle part 32 abuts against the lower surface of the guiding rod 11, and the lower end side walls of the two grooves 112 are clamped in the two U-shaped openings.

[0089] In this embodiment, the connecting piece 33 is used to fixedly connect the second buckle part 32 and the slip form machine 31. When the slip form machine 31 moves forward, the slip form machine 31 drives the second buckle part 32 to slide along the guiding rod 11 through the connecting piece 33 to limit the traveling route of the slip form machine 31.

[0090] In this embodiment, the connecting piece 33 can be an ordinary connecting column or a connecting piece with a variable length. Preferably, the connecting piece 33 includes a base arranged on the buckle main body part of the second buckle part 32 and a hydraulic cylinder fixedly connected to the base. The piston rod of the hydraulic cylinder is connected to the slip form machine 31.

[0091] When the length of the connecting piece 33 can be changed, the distance between the slip form machine 31 and the bottom of the drainage ditch can be changed, so as to meet the requirements of different concrete pouring thicknesses.

[0092] The state of the construction device at the limit position is specifically described as follows:

[0093] When the construction device is in the excavation state, the excavation mechanism 20 is located at a position close to the pressing frame 152, and the slip form construction mechanism 30 is located at the rear end of the guiding rod. At this time, both the excavation mechanism 20 and the sliding mechanism 30 can move forward to perform excavation work and pouring work.

[0094] When the excavation mechanism 20 and the sliding mechanism 30 work one after another (not simultaneously), specifically: when the first sliding component 12 and the second sliding component 13 are in the locked state, the excavation mechanism 20 advances along the guide rod in a direction away from the pressing frame to excavate the drainage ditch; when the excavation mechanism 20 slides to the front end of the guide rod 11, the excavation mechanism 20 stops advancing. At the same time, the piston rod of the second hydraulic jack of the excavation mechanism 20 no longer extends and retracts; then, the formwork construction mechanism 30 advances along the guide rod 11 in a direction close to the pressing frame 152 to pour the bottom and side walls of the drainage ditch. When the formwork construction mechanism 30 slides to a position close to the pressing frame 152, the formwork construction mechanism 30 stops advancing; then, the piston rod of the first hydraulic jack 151 shortens to make the pressing frame 152 spaced from the bottom of the drainage ditch, so as to unlock the first sliding component 12 and the second sliding component 13; the first sliding component 12 and the second sliding component 13 slide along the tracks on both sides of the drainage ditch and drive the pressing component 15 to move until returning to the excavation state of the construction device.

[0095] When the excavation mechanism 20 and the sliding mechanism 30 work simultaneously, specifically: when the first sliding component 12 and the second sliding component 13 are in the locked state, the excavation mechanism 20 advances along the guide rod 11 in a direction away from the pressing frame 152 to excavate the drainage ditch. When the excavation mechanism 20 slides to the front end of the guide rod, the excavation mechanism stops advancing. At the same time, the formwork construction mechanism advances along the guide rod in a direction close to the pressing frame to pour the bottom and side walls of the drainage ditch. When the formwork construction mechanism 30 slides to a position close to the pressing frame 152, the formwork construction mechanism 30 stops advancing; after both the excavation mechanism 20 and the formwork construction mechanism 30 stop working, the piston rod of the first hydraulic jack 151 shortens to make the pressing frame 152 spaced from the bottom of the drainage ditch, so as to unlock the first sliding component 12 and the second sliding component 13; the first sliding component 12 and the second sliding component 13 slide along the tracks on both sides of the drainage ditch and drive the pressing component 15 to move until returning to the excavation state of the construction device.

[0096] It can be understood that when the excavation mechanism 20 and the formwork construction mechanism 30 stop advancing, both also stop working. At the same time, the second hydraulic jack 24 of the excavation mechanism 20 retracts to perform the next cycle of work.

[0097] The present invention also provides a construction method for a drainage ditch. The construction method uses the construction device described above for construction. The construction method includes multiple cycles of construction. Each cycle of construction includes:

[0098] When the construction device is in the state to be excavated, the excavation mechanism is located at a first position close to the pressing frame, and the formwork construction mechanism is located at a second position far from the pressing frame;

[0099] The piston rod of the first hydraulic jack extends to press the pressing frame against the bottom of the drainage ditch, so as to lock the first sliding assembly and the second sliding assembly, and the excavation mechanism advances along the guide rod in a direction away from the pressing frame to excavate the drainage ditch;

[0100] When the excavation mechanism slides to a first target position, the excavation mechanism stops advancing, and the formwork construction mechanism advances along the guide rod in a direction close to the pressing frame to pour the bottom and side walls of the drainage ditch;

[0101] When the formwork construction mechanism slides to a second target position close to the pressing frame, the formwork construction mechanism stops advancing, and the piston rod of the first hydraulic jack shortens to set the pressing frame at an interval from the bottom of the drainage ditch, so as to unlock the first sliding assembly and the second sliding assembly;

[0102] The first sliding assembly and the second sliding assembly slide along the tracks on both sides of the drainage ditch and drive the pressing assembly to move until returning to the state to be excavated of the construction device.

[0103] Preferably, the first position is the critical position where the excavation mechanism is close to the pressing frame, the second position is the rearmost end of the guide rod, the first target position is the foremost end of the guide rod, and the second target position is the critical position where the formwork construction mechanism is close to the pressing frame. In this way, the excavation length of the excavation mechanism can be maximized, the pouring length of the formwork construction mechanism can be maximized, and the construction period can be reduced.

[0104] The above-mentioned critical position refers to the closest position that can be approached.

[0105] The present invention also provides a construction method for a drainage ditch. The construction method uses the construction device described above in the claims for construction. The construction method includes multiple cycles of construction, and each cycle of construction includes:

[0106] When the construction device is in the state to be excavated, the excavation mechanism is located at a third position close to the pressing frame, and the formwork construction mechanism is located at a fourth position far from the pressing frame;

[0107] The piston rod of the first hydraulic jack extends to press the pressing frame against the bottom of the drainage ditch, so as to lock the first sliding assembly and the second sliding assembly. The excavation mechanism advances along the guide rod in a direction away from the pressing frame to excavate the drainage ditch. When the excavation mechanism slides to the third target position, the excavation mechanism stops advancing. At the same time, the formwork construction mechanism advances along the guide rod in a direction close to the pressing frame to pour the bottom and side walls of the drainage ditch. When the formwork construction mechanism slides to the fourth target position close to the pressing frame, the formwork construction mechanism stops advancing;

[0108] After both the excavation mechanism and the formwork construction mechanism stop working, the piston rod of the first hydraulic jack shortens to set a gap between the pressing frame and the bottom of the drainage ditch, so as to unlock the first sliding assembly and the second sliding assembly;

[0109] The first sliding assembly and the second sliding assembly slide along the tracks on both sides of the drainage ditch and drive the pressing assembly to move until they return to the state where the construction device is ready for excavation.

[0110] Preferably, the third position is the critical position where the excavation mechanism is close to the pressing frame, the fourth position is the rear end of the guide rod, the third target position is the front end of the guide rod, and the fourth target position is the critical position where the formwork construction mechanism is close to the pressing frame. In this way, the excavation length of the excavation mechanism can be maximized, and the pouring length of the formwork construction mechanism can be maximized, reducing the number of cyclic construction times.

[0111] The above-mentioned critical position refers to the closest position that can be approached.

[0112] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions and substitutions can still be made, which should all be regarded as belonging to the protection scope of the present invention.
