Description

Technical Field

[0001] This invention relates to the field of measuring equipment, and more particularly to a measuring device, a construction method, and a river dam body for river dam construction. Background Technology

[0002] In river management and ecological restoration projects, traditional river dams cannot meet the requirements for river purification and filtration. Currently, to achieve the filtration function of the river, the bottom of the river is filled with stones such as rubble, and pine piles are driven into the upstream and downstream sections of the river. Downstream, two rows of pine piles are typically driven in a staggered pattern, and a filter layer is set between the pine piles to achieve the filtration effect on the water flowing through the river.

[0003] During the process of driving pine stakes into the riverbed, it is necessary to determine the spacing between the stakes to ensure that the spacing meets the design requirements. This necessitates measuring the stake position and marking it before each driving operation. This measurement method is rather cumbersome and inconvenient to operate.

[0004] Therefore, it is necessary to provide a new surveying device for river dam construction to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a surveying device for river dam construction, solving the problem of the cumbersome technical issue that existing river dam construction methods require measuring pile positions and marking them before each pile driving operation.

[0006] To solve the above-mentioned technical problems, the present invention provides a surveying device for river dam construction, comprising:

[0007] Two brackets, each bracket including a main rod, a mounting plate and a sliding rod, a U-shaped plate connecting one end of the two main rods, the mounting plate being located at the other end of the main rods, and the sliding rod being located at the bottom of the main rods;

[0008] A spacing measuring mechanism includes a measuring plate, a rotary motor, two assembly plates, and multiple limiting clamps. The assembly plates are arranged in a one-to-one correspondence with the slide rods, and the assembly plates are slidably mounted on the slide rods. The measuring plate is rotatably mounted between the two assembly plates and spaced apart from the U-shaped plate. The measuring plate is provided with scale values, and multiple assembly holes are opened on the measuring plate corresponding to the scale values. The limiting clamps are detachably mounted to the measuring plate through the assembly holes. The rotary motor is used to drive the measuring plate to rotate.

[0009] A lifting device, comprising a mounting frame and a lifting cylinder; the lifting cylinder is mounted on the main member via the mounting frame, and is used to lift the spacing measuring mechanism.

[0010] A ranging device is installed at the lifting end of the lifting device.

[0011] Preferably, the lifting end of the lifting cylinder passes through the main rod and is connected to the assembly plate.

[0012] Preferably, there are two lifting devices, and the ranging device is installed at the lifting end of one of the lifting cylinders.

[0013] Preferably, the limiting clamp includes a connector and a clamp ring, the connector is disposed on the clamp ring, and the connector and the assembly hole are detachably connected.

[0014] Preferably, the lifting device further includes a lifting hook, and the ranging device is installed at the lifting end of the lifting cylinder via the lifting hook;

[0015] The measuring equipment for river dam construction also includes a hook structure, which is installed on the measuring plate;

[0016] When the rotary motor drives the measuring plate and the hook structure to rotate 90 degrees, the hook structure is assembled with the lifting hook.

[0017] Preferably, the measuring equipment for river dam construction further includes an end support structure;

[0018] The end support structure includes a driving member, two U-shaped frames and two sliding frames. The two sliding frames are respectively installed at both ends of the measuring plate. The two ends of each U-shaped frame are slidably connected to the two sliding frames. The driving member is used to drive the two U-shaped frames to open. The supporting surfaces of the two U-shaped frames face the limiting hoop.

[0019] Preferably, the driving component is a plurality of driving blocks, and each of the two ends of the U-shaped frame is equipped with a driving block, with adjacent driving blocks spaced apart;

[0020] The hook structure includes an L-shaped frame, a U-shaped sleeve, and a ball rod. The L-shaped frame is slidably mounted on the measuring plate within a preset stroke. The U-shaped sleeve is mounted on one end of the L-shaped frame and sleeved on two adjacent drive blocks. The cylindrical end of the ball rod is mounted on the U-shaped sleeve and located between the two drive blocks.

[0021] Preferably, the spacing measuring mechanism further includes a lifting block, which is mounted on the measuring plate, and one end of the L-shaped frame passes through the lifting block and is connected to the U-shaped sleeve.

[0022] To address the aforementioned technical problems, the present invention also provides a method for constructing a river dam, comprising the following steps:

[0023] S1. Backfill the bottom of the riverbed with rubble to form a drainage layer;

[0024] S2. Drive a row of pine piles into the upper reaches of the river, and then drive two rows of pine piles into the lower reaches of the river in a staggered pattern. During the pile driving process, use the measuring equipment for the construction of the river dam to determine the spacing between two adjacent pine piles.

[0025] S3. Lay two more layers of zeolite in the riverbed.

[0026] To solve the above-mentioned technical problems, the present invention also provides a river dam body, which is constructed using the aforementioned river dam body construction method.

[0027] Compared with related technologies, the surveying equipment for river dam construction provided by this invention has the following advantages:

[0028] To obtain the required spacing between pine stakes, adjust the position of the limiting hoops according to the scale values ​​on the measuring board so that the spacing between the limiting hoops meets the spacing requirements between the pine stakes. Then, insert the corresponding pine stakes into the limiting hoops. In other words, use the measuring board in conjunction with the limiting hoops to measure and determine the stake position between adjacent pine stakes.

[0029] When one end of the pine stake is inserted into the limiting hoop, the other end of the pine stake can be supported by a U-shaped plate, reducing the load of the pine stake on the limiting hoop.

[0030] The distance measuring device is initially set to a horizontal direction. Before driving the piles, a reference object is determined, and the distance measuring device measures the distance between the reference object and the target object to determine the starting position of a row of pine piles on the measuring board.

[0031] Then, the rotary motor drives the measuring plate to rotate 90 degrees, erecting the pine stakes. As the pile driving equipment presses the pine stakes down into the river channel in sequence, after a row of pine stakes is driven into the river channel, the measuring plate is lifted by the lifting device, so that the limiting hoop and the measuring plate rise above the pine stakes, thus facilitating the separation of the ranging equipment from the driven pine stakes.

[0032] Repeat the above steps to proceed with the piling work at the next location.

[0033] Using this surveying equipment, the distance between adjacent pine stakes can be quickly measured and determined, and the starting position of a row of pine stakes on the measuring board can be determined, which facilitates the pile driving operation. Attached Figure Description

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0061] This invention provides a measuring device for the construction of river dams.

[0062] First Embodiment

[0063] Please see Figure 1 In the first embodiment of the present invention, the measuring equipment for river dam construction includes:

[0064] Two supports 1, each support 1 including a main rod 101, a mounting plate 103 and a sliding rod 102, a U-shaped plate 104 connecting one end of the two main rods 101, the mounting plate 103 being located at the other end of the main rods 101, and the sliding rod 102 being located at the bottom of the main rods 101;

[0065] The spacing measuring mechanism 2 includes a measuring plate 21, a rotary motor 24, two assembly plates 23, and multiple limiting clamps 22. The assembly plates 23 are arranged one-to-one with the slide rods 102 and are slidably mounted on the slide rods 102. The measuring plate 21 is rotatably mounted between the two assembly plates 23 and spaced apart from the U-shaped plate 104. The measuring plate 21 has scale values ​​and multiple assembly holes 211 are opened on the measuring plate 21 corresponding to the scale values. The limiting clamps 22 are detachably mounted on the measuring plate 21 through the assembly holes 211. The rotary motor 24 is used to drive the measuring plate 21 to rotate.

[0066] The lifting device 4 includes a mounting frame 41 and a lifting cylinder 42; the lifting cylinder 42 is mounted on the main rod 101 via the mounting frame 41, and the lifting cylinder 42 is used to lift the spacing measuring mechanism 2.

[0067] The ranging device 3 is installed at the lifting end of the lifting device 4.

[0068] In this embodiment, the lifting end of the lifting cylinder 42 passes through the main rod 101 and is connected to the assembly plate 23.

[0069] The ranging device 3 can be a laser ranging device, an ultrasonic ranging device, or a radar ranging device.

[0070] Please see Figure 2First, obtain the spacing requirements of the pine piles 8. Based on the scale value on the measuring plate 21, adjust the position of the limiting hoop 22 so that the spacing between the limiting hoop 22 meets the spacing requirements between the pine piles 8. Then, insert the corresponding pine piles 8 into the limiting hoop 22. That is, use the measuring plate 21 in conjunction with the limiting hoop 22 to measure and determine the pile position between adjacent pine piles 8.

[0071] When one end of the pine stake 8 is inserted into the limiting hoop 22, the other end of the pine stake 8 can be supported by the U-shaped plate 104, reducing the load of the pine stake 8 on the limiting hoop 22.

[0072] Please refer to it again. Figure 1 The distance measuring device 3 is set to a horizontal starting direction. Before driving the pile, a reference object is determined. The distance measuring device 3 detects the distance between itself and the reference object to determine the starting position of a row of pine piles 8 on the measuring plate 21.

[0073] Please refer to the following: Figure 2 and Figure 3 Then, the rotary motor 24 drives the measuring plate 21 to rotate 90 degrees, erecting the pine piles 8. When the pile driving equipment presses the pine piles 8 down into the river channel in sequence, after a row of pine piles 8 are driven into the river channel, the measuring plate 21 is lifted by the lifting device 4, so that the limiting hoop 22 and the measuring plate 21 rise above the pine piles 8, thereby facilitating the separation of the distance measuring equipment from the driven pine piles 8.

[0074] Repeat the above steps to proceed with the piling work at the next location.

[0075] Using this surveying equipment, the distance between adjacent pine piles 8 can be quickly measured and determined, and the starting position of a row of pine piles 8 on the measuring plate 21 can be measured and determined, which facilitates the pile driving operation.

[0076] It is understandable that reference points can be set at the outermost edge of the riverbed during the initial pile driving.

[0077] Please see Figure 4 In this embodiment, the piling equipment for the pine piles 8 is an excavator. The excavator bucket is used to press down the pine piles 8 for piling, or the excavator bucket can be replaced with a piling head.

[0078] When using this measuring device, the mounting plate 103 of the bracket 1 is detachably installed to the running frame of the excavator's track wheels 11.

[0079] The mounting plate 103 has holes; the installation method is to pre-set a fixing bracket on the traveling frame, and the fixing bracket has corresponding holes, and then install it by using threaded bolts to fit the holes.

[0080] By mounting the measuring equipment on the excavator's traveling frame, the frame remains stationary while the excavator is working in one position and the operator's cab and boom are moving. This facilitates easy passage of the excavator lifting equipment through river channels.

[0081] In this embodiment, the spacing between adjacent pine stakes 8 is between 10 and 50 centimeters, and the height of the pine stakes 8 exposed above the water surface is not less than 10 centimeters, preferably 30 centimeters.

[0082] Please refer to it again. Figure 1 A stop block is installed at the bottom end of the slide bar 102. The main rod 101 is connected to the mounting plate 103 in an L-shape, so that after the mounting plate 103 is installed with the excavator's walking frame, the measuring plate 21 is better positioned above the water surface.

[0083] The number of lifting devices 4 can be one or two.

[0084] In this embodiment, there are two lifting devices 4, and the ranging device 3 is installed at the lifting end of a lifting cylinder 42.

[0085] The two main rods 101 are provided with grooves on opposite sides. The lifting end of the lifting cylinder 42 passes through the groove through the main rod 101. When the distance measuring mechanism 2 is subsequently lifted to a height above the top of the pine stake 8, the distance measuring device 3 can move along the groove without being blocked by the bracket 1.

[0086] As an optional embodiment, the measuring plate 21 is provided with rotating shafts at both ends, and the two rotating shafts are respectively rotatably connected to the corresponding assembly plate 23. The rotary motor 24 is mounted on one of the corresponding assembly plates 23, and the rotating shaft on the assembly plate 23 is connected to the drive shaft of the rotary motor 24.

[0087] Preferably, a protective sleeve is provided outside the rotary motor 24, and the protective sleeve is connected to the mounting plate 23 to protect the rotary motor 24 and prevent river water from contacting the rotary motor 24.

[0088] As another optional embodiment, one end of the measuring plate 21 is rotatably connected to a corresponding assembly plate 23 via a rotating shaft, and the rotary motor 24 is mounted on another assembly plate 23. The drive shaft of the rotary motor 24 passes through the assembly plate 23 and is connected to the other end of the measuring plate 21.

[0089] The rotary motor 24 and the lifting cylinder 42 can be powered by the excavator's power supply, or they can be powered by a separate power supply device.

[0090] Please see Figure 5In this embodiment, the limiting clamp 22 includes a connector 222 and a clamp ring 221. The connector 222 is disposed on the clamp ring 221, and the connector 222 and the assembly hole 211 are detachably connected. The clamp ring 221 can be a single ring, and the diameter of the clamp ring 221 is adapted to the diameter of the pine stake 8.

[0091] As an optional embodiment, the connector 222 is a threaded shaft and a nut. The threaded shaft is installed on the limiting clamp 22, and assembly is achieved by threading the threaded shaft through the assembly hole 211 and connecting it to the nut. Multiple threaded shafts are installed on each limiting clamp 22, and in this embodiment, there are two.

[0092] As another alternative to this embodiment, the connector 222 can also adopt a locking structure.

[0093] Please see Figure 6 It is understood that in other embodiments, the hoop 221 includes a bolt 2212, a nut 2213 and two half hoops 2211, and the two half hoops 2211 are detachably connected to the nut 2213 by the bolt 2212.

[0094] Specifically, each half hoop 2211 has a flange on its side, and a connecting hole is provided on the flange. The bolt 2212 passes through the connecting hole and is tightened by the nut 2213.

[0095] By setting the limiting hoop 22 into two half hoops 2211, and by using bolts 2212 and nuts 2213, the distance between the two half hoops 2211 can be adjusted, that is, the tightness can be adjusted. The distance between the two half hoops 2211 can be adjusted adaptively according to the diameter of the pine stake 8.

[0096] The nuts 2213 and 222 have multiple raised lines on their surfaces to facilitate manual tightening of the nuts 2213 and 222.

[0097] In the above embodiments, the limiting hoop 22 only needs to limit the pine pile 8 in the circumferential direction, and does not need to clamp the pine pile 8. During the process of driving the pine pile 8 into the river channel, it is not necessary to unlock the limiting hoop 22.

[0098] Alternatively, a limiting hoop 22 can be set to clamp the pine pile 8. After rotating it to vertical, it can be unlocked in sequence to carry out the pile driving work.

[0099] Alternatively, the limiting hoop 22 can be set to limit the pine pile 8 in the circumferential direction without clamping the pine pile 8. Other auxiliary structures can be set to limit the vertical slippage of the pine pile 8.

[0100] Second Embodiment

[0101] Please refer to the following: Figure 7 and Figure 8 The measuring equipment for river dam construction provided in the second embodiment differs from that in the first embodiment in that the lifting end of the lifting cylinder 42 is not directly connected to the assembly plate 23.

[0102] The lifting device 4 also includes a lifting hook 43, and the ranging device 3 is installed at the lifting end of the lifting cylinder 42 via the lifting hook 43;

[0103] The measuring equipment for river dam construction also includes a hook structure 6, which is installed on the measuring plate 21.

[0104] When the rotary motor 24 drives the measuring plate 21 and the hook structure 6 to rotate 90 degrees, the hook structure 6 is assembled with the lifting hook 43.

[0105] Specifically, when the rotary motor 24 drives the measuring plate 21 to rotate 90 degrees to make the pine stake 8 stand up, the measuring plate 21 drives the hook structure 6 to rotate 90 degrees so that the hook structure 6 is assembled with the lifting hook 43.

[0106] Subsequently, the lifting cylinder 42 can lift the measuring plate 21 through the lifting hook 43 and the hook structure 6, thereby raising the spacing measuring mechanism 2. By setting the hook structure 6 to engage with the lifting hook 43, the lifting device 4 and the hook structure 6 can provide axial auxiliary limit for the measuring plate 21, so that the pine pile 8 can be kept more stably vertical and the limiting load of the rotary motor 24 can be reduced.

[0107] Please refer to it again. Figure 8 In a preferred embodiment, the hook structure 6 is provided with a fixing hole 611. When the hook structure 6 is assembled with the lifting hook 43, the fixing hole 611 is aligned with the hook protrusion of the lifting hook 43.

[0108] When the hook structure 6 is assembled with the lifting hook 43, the lifting cylinder 42 lifts the lifting hook 43, so that the hook part of the lifting hook 43 protrudes through the fixing hole 611 on the hook structure 6.

[0109] This makes the assembly of the lifting hook 43 and the hook structure 6 more stable, and improves the stability of the lifting cylinder 42 in lifting the measuring plate 21 through the lifting hook 43 and the hook structure 6.

[0110] In this embodiment, the hook structure 6 is an L-shaped arm, one end of which is fixedly connected to the measuring plate 21, and the fixing hole 611 is opened at the other end of the L-shaped arm.

[0111] Third Embodiment

[0112] Please refer to the following: Figure 9 and Figure 10The measuring equipment for river dam construction provided in the third embodiment differs from that in the second embodiment in that the measuring equipment for river dam construction also includes an end support structure 5;

[0113] The end support structure 5 includes a driving member 53, two U-shaped frames 52 and two sliding frames 51. The two sliding frames 51 are respectively installed at both ends of the measuring plate 21. The two ends of each U-shaped frame 52 are slidably connected to the two sliding frames 51. The driving member 53 is used to drive the two U-shaped frames 52 to open. The supporting surfaces of the two U-shaped frames 52 face the limiting hoop 22.

[0114] Please refer to the following: Figure 10 and Figure 11 When the two U-shaped frames 52 are closed, they can limit the support of the tip of the pine pile 8. On the one hand, this can prevent the pine pile 8 from sliding down due to gravity and its bottom end from contacting the paved stones in the riverbed in advance during the process of rotating the measuring plate 21 by the rotating motor 24 to make the pine pile 8 vertical, thereby improving the vertical accuracy of the pine pile 8. On the other hand, it can also improve the flexibility of the equipment. After the pine pile 8 is rotated to vertical, the entire equipment can be moved and adjusted in position due to the support of the end support structure 5.

[0115] After the pine pile 8 rotates to a vertical position and reaches the designated position, the drive component 53 drives the two U-shaped frames 52 to open. The U-shaped frames 52 do not support the pine pile 8. At this time, the pine pile 8 can be driven into the river channel using the pile driving equipment.

[0116] Please refer to it again. Figure 10 The sliding frame 51 includes a U-shaped support frame and a sliding arm. The U-shaped support frame is installed on the measuring plate 21, and the sliding arm is installed inside the U-shaped support frame. The two ends of the U-shaped frame 52 are sleeved on the corresponding sliding arms to form a sliding connection.

[0117] Please refer to it again. Figure 10 As an optional embodiment, the driving member 53 is a plurality of driving blocks, and each of the two ends of the U-shaped frame 52 is equipped with a driving block, with two adjacent driving blocks spaced apart.

[0118] The hook structure 6 includes an L-shaped frame 61, a U-shaped sleeve 62, and a ball rod 63. The L-shaped frame 61 is slidably mounted on the measuring plate 21 within a preset stroke. The U-shaped sleeve 62 is mounted on one end of the L-shaped frame 61 and sleeved on two adjacent driving blocks. The cylindrical end of the ball rod 63 is mounted on the U-shaped sleeve 62 and located between the two driving blocks.

[0119] The fixing hole 611 is provided at the other end of the L-shaped frame 61.

[0120] In this embodiment, along the setting direction of the cue stick 63, the distance between the spherical part of the cue stick 63 and the driving member 53 (driving block) is not less than the length of the U-shaped sleeve 62 sleeved on the part of the driving member 53 (driving block).

[0121] It is understood that the cue stick 63 includes a shaft (cylindrical end) and a spherical part, with the spherical part connected to one end of the shaft and the other end of the shaft mounted on the U-shaped sleeve 62.

[0122] By fitting the U-shaped sleeve 62 onto the two driving components 53 (driving blocks), the two driving components 53 (driving blocks) can be limited, that is, the two U-shaped frames 52 can be limited, so that the two U-shaped frames 52 are kept closed, thereby limiting the tip of the pine stake 8.

[0123] When it is necessary to open the two U-shaped frames 52 to facilitate the driving of pine stakes 8 into the riverbed, the lifting cylinder 42 pulls up the L-shaped frame 61 through the lifting hook 43. The L-shaped frame 61 drives the U-shaped sleeve 62 to move upward and separate from the two driving components 53 (driving blocks).

[0124] For details, please refer to Figure 12 (b) to Figure 12 (d) Continue to lift the L-shaped frame 61, and the cue stick 63 pushes the two driving parts 53 (driving blocks) to the sides to separate. The two driving parts 53 drive the two U-shaped frames 52 to open, and the bottom tips of multiple pine stakes 8 pass through the two U-shaped frames 52, as shown. Figure 12 In (d), the tips of multiple subsequent pine stakes 8 can gradually push the two U-shaped frames 52 apart, such as Figure 13 At this point, the pine stake 8 can pass through the two U-shaped frames 52 and enter the river channel.

[0125] When the U-shaped frame 52 opens, the L-shaped frame 61 slides up to its maximum stroke. When the spacing measuring mechanism 2 needs to be raised so that its lowest point is higher than the top of the pine stake 8, the L-shaped frame 61 can lift the measuring plate 21 when it is raised again, which in turn can move the spacing measuring mechanism 2 upward.

[0126] Thus, by using the lifting device 4 in conjunction with the hook structure 6, the drive component 53 can be driven to open the two U-shaped frames 52.

[0127] Please refer to it again. Figure 10 Preferably, the bottom of each of the two adjacent driving members 53 (driving blocks) on the opposite side is set as an inclined surface, so as to facilitate interaction with the cue stick 63 and push the driving member 53 (driving block) to open.

[0128] Subsequent staff can assist in closing the two U-shaped frames 52 together, so that the U-shaped sleeve 62 can be fitted onto the two driving components 53 (driving blocks) again.

[0129] Preferably, the diameter of the spherical part of the club 63 can be set to be no less than that of the pine stake 8 (or the spherical part can be set as a trapezoidal block, the width of which is no less than the diameter of the pine stake 8), so that the spherical part can be used to directly expand the two U-shaped frames 52 to a diameter greater than or equal to that of the pine stake 8, allowing the pine stake 8 to directly enter the river channel.

[0130] As another optional embodiment, the driving component 53 includes a fixed plate, a drive motor, a threaded rod, and two threaded sleeves. The drive motor is mounted on the sliding frame 51 via the fixed plate, and the threaded rod is mounted on the output shaft of the drive motor. The two ends of the threaded rod have opposite threads, and the two threaded sleeves are threadedly connected to the two ends of the threaded rod. The threaded sleeves are connected to the two U-shaped frames 52 via connecting blocks. By driving the threaded rod to rotate via the drive motor, the two threaded sleeves are opened or closed, thereby opening or closing the two U-shaped frames 52.

[0131] The L-shaped frame 61 is slidably mounted on the measuring plate 21 within a preset stroke.

[0132] As an optional embodiment, a sliding groove is provided on the L-shaped frame 61, and a slider is installed on the measuring plate 21. The slider slides into the sliding groove to form a sliding assembly. When the L-shaped frame 61 is raised, when the inner wall of the end of the sliding groove interacts with the slider, the slider can drive the measuring plate 21 to be raised, thereby realizing the raising of the distance measuring mechanism 2.

[0133] Please refer to it again. Figure 10 As another optional embodiment, the spacing measuring mechanism 2 further includes a lifting block 25, which is mounted on the measuring plate 21. One end of the L-shaped frame 61 passes through the lifting block 25 and is connected to the U-shaped sleeve 62.

[0134] Please refer to the following: Figure 12 (d) and Figure 13 The lifting cylinder 42 lifts the ranging device 3, and the U-shaped sleeve 62 moves up to abut against the lifting block 25. Subsequently, after all the pine stakes 8 on the measuring plate 21 are driven into the river, the lifting cylinder 42 continues to lift the L-shaped frame 61. The U-shaped sleeve 62 and the lifting block 25 work together to lift the measuring plate 21, so that the measuring plate 21, the limiting hoop 22 and the ball rod 63 are all above the top of the pine stakes 8. Thus, the pine stakes 8 will not affect the horizontal movement of the entire measuring equipment to the next position for pile driving.

[0135] The lifting block 25 can help limit the L-shaped frame 61, and the part of the lifting block 25 that is fitted onto the L-shaped frame 61 is equipped with a rubber pad to increase friction, so that the L-shaped frame 61 will not slide freely without being subjected to external force.

[0136] Please refer to it again. Figure 10Preferably, there are two lifting blocks 25, which are installed at both ends of the measuring plate 21 and connected to the U-shaped support frame of the sliding frame 51. Two corresponding hook structures 6 are provided at both ends of the measuring plate 21, so that the lifting cylinder 42 can use the hook structures 6 and the lifting blocks 25 to drive the measuring plate 21 to rise from both ends.

[0137] Please see Figure 14 The lifting device 4 also includes a marker rope 44, which connects the two lifting hooks 43;

[0138] The ranging device 3 is rotatably mounted on one of the lifting hooks 43.

[0139] When measuring the distance to the water surface, the detection medium emitted by the ranging device 3 can directly interact with the water surface to detect the distance between the water surface and the water surface.

[0140] Laser ranging devices emit laser beams, receive the echoes reflected from the target surface, and calculate the distance based on the laser propagation time (or phase difference). Ultrasonic ranging devices emit ultrasonic pulses, receive the echoes reflected from the water surface, and calculate the distance based on the sound wave propagation time.

[0141] Alternatively, a marker plate can be placed on the water surface below the ranging device 3 to work with the ranging device 3, achieving a more stable ranging effect.

[0142] Specifically, the rotating motor 24 drives the measuring plate 21 to rotate 90 degrees, erecting the pine stake 8, and the rotating distance measuring device 3 rotates 90 degrees so that its detection end faces the water surface.

[0143] At this time, the L-shaped frame 61 is assembled with the lifting hook 43. After the pine stake 8 is erected, the distance measuring device 3 detects the distance to the water surface to determine the distance from the marker rope 44 to the water surface.

[0144] The lifting cylinder 42 drives the lifting hook 43 to rise, thereby moving the ranging device 3 and the marker rope 44 to the preset height. Subsequently, when the piling equipment presses the pine pile 8 into the river channel, when the piling head contacts the marker rope 44, the piling of one pine pile 8 is completed, thus making it easy to determine the height of the pine pile 8 above the water surface.

[0145] In this embodiment, when the lifting device 4 raises the marker rope 44 to a preset height, the U-shaped sleeve 62 still does not contact the lifting block 25, meaning there is a gap between the U-shaped sleeve 62 and the lifting block 25, thus adapting to river water depths within a certain range. When the water depth changes, the lifting cylinder 42 raises the marker rope 44 to the preset height, and the height raised by the lifting cylinder 42 will change, thus adapting to height changes within a certain range.

[0146] Preferably, when the ranging device 3 is rotated downwards, the detection end and the marker rope 44 are at the same height. The distance detected by the ranging device 3 to the water surface is the distance between the marker rope 44 and the water surface.

[0147] The color of the marking rope 44 is yellow or red, which serves as a better warning.

[0148] Please see Figure 13 A connecting frame is horizontally installed on the lifting hook 43. The bottom of the connecting frame is open. One end of the ranging device 3 is symmetrically connected to a rotating shaft. The rotating shaft is rotatably connected to the connecting frame, and a knob is threadedly connected to one side of the connecting frame.

[0149] When the ranging device 3 is rotated to a horizontal position, the top of the ranging device 3 is in contact with the top of the connecting frame. At this time, the ranging device 3 is limited by tightening the knob to press against it.

[0150] When the distance measuring device 3 is rotated 90 degrees so that it faces vertically downwards, the side wall of the distance measuring device 3 is in contact with the side wall of the connecting frame. Similarly, rotating the knob will press the distance measuring device 3 tightly against the frame.

[0151] The working principle of the surveying equipment for river dam construction provided in this embodiment is as follows:

[0152] Please see Figure 11 When the measuring device is working, it first adjusts the position of the limiting hoop 22 according to the spacing requirements of the pine piles 8 and the scale value on the measuring plate 21, so that the spacing between the limiting hoop 22 meets the spacing requirements of the pine piles 8. Then, the corresponding pine piles 8 are inserted into the limiting hoop 22, and their bottom ends abut against the end support structure 5. That is, the measuring plate 21 and the limiting hoop 22 are used to determine the pile position between adjacent pine piles 8.

[0153] Please see Figure 14 The initial detection direction of the ranging device 3 is set horizontally. When driving piles, a reference object can be set on the outermost side of the river channel. The ranging device 3 can then detect the distance between itself and the reference object to determine the starting pile position of a row of pine piles 8 on the measuring plate 21. The excavator moves the corresponding distance.

[0154] Then, the rotary motor 24 drives the measuring plate 21 to rotate 90 degrees, erecting the pine stake 8, as shown. Figure 12 In (b) the rotating distance measuring device 3 rotates ninety degrees, at which point an L-shaped frame 61 is assembled with the lifting hook 43.

[0155] Please see Figure 13After the pine stake 8 is erected, the detection end of the distance measuring device 3 faces the water surface. The distance measuring device 3 detects the distance to the water surface, and the lifting cylinder 42 drives the lifting hook 43 to rise, thereby moving the distance measuring device 3 and the marker rope 44 to the preset height. Subsequently, when the piling equipment presses the pine stake 8 into the river channel, when the bucket contacts the marker rope 44, the piling of one pine stake 8 is completed, thus determining the height of the pine stake 8 above the water surface. After multiple pine stakes 8 on the measuring plate 21 are completed, the above operation is repeated to continue piling.

[0156] Please refer to the following: Figure 12 (c) and Figure 12 In step (d), as the marker rope 44 moves up to the preset height, the L-shaped frame 61 drives the U-shaped sleeve 62 to move up and separate from the two driving parts 53 (driving blocks). The L-shaped frame 61 continues to rise, causing the ball stick 63 to push the two driving parts 53 to both sides, causing the two U-shaped frames 52 to open, so that the bottom tip of the pine stake 8 can pass through the two U-shaped frames 52. Subsequently, the two U-shaped frames 52 can be squeezed apart and enter the river channel.

[0157] Subsequently, after all the pine stakes 8 on the measuring plate 21 have been driven into the riverbed, the lifting cylinder 42 continues to lift the L-shaped frame 61. The L-shaped frame 61 drives the U-shaped sleeve 62 to abut against the lifting block 25. At this time, the U-shaped sleeve 62 drives the measuring plate 21 to lift, so that the measuring plate 21, the limiting hoop 22 and the ball rod 63 are all above the top of the pine stakes 8, so that the pine stakes 8 will not affect the horizontal movement of the entire measuring equipment to the next position for pile driving.

[0158] In one state, the lifting device 4 can raise the marking rope 44 to measure and mark the distance of the pine stake 8 that is exposed outside the water surface. In another state, it can raise the measuring plate 21 so that the lowest end of the spacing measuring mechanism 2 is above the top of the pine stake 8, thereby moving the entire measuring device to the next position for measurement. During this process, it can also open the two U-shaped frames 52 so that the tip of the pine stake 8 can pass through the two U-shaped frames 52.

[0159] The present invention also provides a method for constructing river dams.

[0160] Please refer to the following: Figure 15 and Figure 16 The construction method for river dams includes the following steps:

[0161] S1. Backfill the bottom of the riverbed with rubble to form a drainage layer;

[0162] S2. Drive a row of pine piles 8 into the upper reaches of the river, and then drive two rows of pine piles 8 into the lower reaches of the river in a staggered pattern. During the pile driving process, use the measuring equipment for the construction of the river dam to determine the spacing between two adjacent pine piles 8.

[0163] Specifically, the mounting plate 103 of the bracket 1 can be installed on the piling equipment;

[0164] S3. Lay two more layers of zeolite in the riverbed.

[0165] Before step S1, the silt and debris in the river channel are removed to provide a stable base surface for subsequent construction.

[0166] When driving in pine stakes (8), a line is laid out at the designated location in the river channel. This involves driving marker stakes into both sides of the river channel and stringing a line between the markers to determine the direction of the pile driving. Subsequent pile driving operations are then carried out using surveying equipment used for river dam construction.

[0167] The downstream installation uses a staggered layout, where two rows of piles are staggered and three adjacent pine piles form an equilateral triangle. The staggered arrangement of the piles creates a "group effect" through the friction between the stones and the mutual mechanical restraint, which is more effective in resisting the lateral slippage of the riverbank soil than a straight arrangement.

[0168] By backfilling with rubble to form a drainage layer, the bearing capacity of the foundation is enhanced, and the pile position is prevented from shifting due to silt compression during pile driving. By setting zeolite, it has the ability to adsorb pollutants such as suspended solids, heavy metals, nitrogen and phosphorus in the water, and the riverbed matrix reinforcement and water purification can be achieved simultaneously.

[0169] Among them, the two zeolite layers are defined as the middle layer and the upper layer, and the middle layer and the upper layer are respectively from the schist layer 9 upwards.

[0170] The middle layer can be made of 20-40mm crushed zeolite, laid for 30-50cm, and the upper layer can be made of 10-20mm granular zeolite, laid for 20-30cm, to ensure that the porosity is ≥40% and the adsorption performance meets the standards.

[0171] Middle layer: Utilizing the adsorption capacity of zeolite, it filters pollutants in the water flow and also serves as a structural filler to bear part of the load.

[0172] Upper layer: Close to the water surface, zeolite can directly contact the water, enhancing the water purification effect, and its porous structure is conducive to the penetration of aquatic plant roots, improving the ecological environment.

[0173] The specific structure of the measuring equipment used for the construction of the river dam is as described in the above embodiments. Since the construction method of the river dam adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0174] The present invention also provides a river dam body.

[0175] Please see Figure 15 and Figure 16A river dam body, constructed using the aforementioned river dam body construction method.

[0176] The river dam body includes a zeolite layer 7, a rubble layer 9, a sedimentation ditch 10, and multiple pine piles 8.

[0177] Specifically, a rubble layer 9 is formed by backfilling rubble at the bottom of the river channel, which facilitates drainage.

[0178] Then, a row of pine piles 8 is driven into the upper reaches of the river, and two rows of pine piles 8 are driven into the lower reaches of the river in a plum blossom pattern to determine the scope of use of the dam.

[0179] Finally, zeolite is laid in the middle and upper layers of the river channel, that is, above the rubble layer 9, to form the zeolite layer 7.

[0180] The sedimentation ditch 10 is located in the zeolite layer 7 in the upper reaches of the river, between the upstream pine pile 8 and the zeolite layer 7.

[0181] By driving pine stakes 8 into the upstream and downstream, the zeolite layer 7 and the flaky stone layer 9 can be limited to prevent the zeolite from being lost with the water flow; by setting up the zeolite layer 7, the zeolite's adsorption capacity is used to filter pollutants in the water flow, enhancing the water purification effect; large impurities filtered out by the zeolite layer 7 enter the sedimentation ditch 10; the sedimentation ditch 10 can be cleaned later.

[0182] The specific structure of the measuring equipment used for the construction of the river dam is as described in the above embodiments. Since all the technical solutions of all the above embodiments are adopted in the construction of the river dam, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0183] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
