Description

Technical Field

[0001] The present application relates to the field of steel sheet pile construction, and in particular to a Larsen steel sheet pile driving inclination detection device and detection method. Background Art

[0002] Steel sheet pile construction refers to the construction process in which steel sheet piles are used to support the foundation pit. Among them, Larsen steel sheet piles are a type of steel sheet piles. Larsen steel sheet piles are also called U-shaped steel sheet piles. As a new type of building material, they are used as retaining walls, water retaining walls, and sand retaining walls when building bridge cofferdams, laying large pipelines, and excavating temporary ditches; they are used as retaining walls, retaining walls, and embankment protection walls at docks and unloading yards, and play an important role in engineering. Larsen steel sheet piles are not only green and environmentally friendly, but also have fast construction speed and low construction costs, and have good waterproofing functions.

[0003] Usually in the construction of steel sheet piles, the steel sheet piles are first hoisted to the pile insertion point by a crane for pile insertion. The locks should be aligned when inserting the piles. After each pile is inserted, the pile cap is put on and hammered lightly. The steel sheet piles are driven in several times. The first time is driven from 20m to 15m, the second time is driven to 10m, the third time is driven to the height of the guide beam, and the fourth time is driven to the designed elevation after the guide frame is removed. When driving the piles, the position and direction of the first and second steel plates must be ensured to be accurate, and measurements are taken every 1m.

[0004] With regard to the above-mentioned related technologies, it is necessary to measure the direction of the steel sheet piles multiple times to improve the accuracy. Such operation is rather cumbersome, resulting in low work efficiency. Summary of the invention

[0005] The purpose of this application is to provide a Larsen steel sheet pile driving inclination detection device and detection method.

[0006] In the first aspect, the present application provides a Larsen steel sheet pile driving inclination detection device adopts the following technical solution:

[0007] A Larsen steel sheet pile insertion inclination detection device comprises a connecting block, one side of the connecting block is provided with a guide piece for inserting the Larsen steel sheet pile, a rotating rod passes through the connecting block and is rotatably connected, an end of the rotating rod away from the Larsen steel sheet pile is provided with a fixed rod perpendicular to the rotating rod, the plane where the rotating rod and the fixed rod are located is parallel to the plane where the Larsen steel sheet pile is located, and the side of the connecting block facing the fixed rod is provided with scales evenly distributed around the axis of the rotating rod.

[0008] By adopting the above technical solution, the fixed rod is vertically inserted into the ground, and then the Larsen steel sheet pile is hoisted, and the lower end of the Larsen steel sheet pile is inserted into the guide member. When the Larsen steel sheet pile is tilted, the guide member and the connecting block are driven to rotate relative to the rotating rod. At this time, the fixed rod and the connecting block rotate relative to each other, and the inclination angle is intuitively displayed through the scale, so as to facilitate the adjustment of the direction of the Larsen steel sheet pile and maintain the verticality of the Larsen steel sheet pile. Therefore, during the Larsen steel sheet pile insertion process, the verticality of the Larsen steel sheet pile can be observed at all times without multiple measurements, thereby simplifying the Larsen steel sheet pile insertion process and improving work efficiency. In addition, the rotating rod points to the position of the previous Larsen steel sheet pile, providing quick and convenient guidance for the direction and positioning of the Larsen steel sheet pile, thereby improving work efficiency and accuracy.

[0009] Optionally, the guide member includes a first guide plate and a second guide plate whose shapes match the shapes of the Larsen steel sheet piles, and one end of the first guide plate close to the connecting block and one end of the second guide plate close to the connecting block are fixedly connected, and the other ends are parallel and oppositely arranged, and the first guide plate is fixedly connected to the connecting block.

[0010] By adopting the above technical solution, the Larsen steel sheet pile can be inserted between the first guide plate and the second guide plate from above. At the same time, since one end of the first guide plate and the second guide plate are parallel to each other and there is an opening, it will not affect the insertion and cooperation between the Larsen steel sheet pile and the adjacent Larsen steel sheet pile, thereby improving the insertion efficiency.

[0011] Optionally, a plurality of guide wheels are provided on opposite sides of the first guide plate and the second guide plate, and axes of the guide wheels are parallel to the first guide plate or the second guide plate.

[0012] By adopting the above technical solution, the guide wheels between the first guide plate and the second guide plate abut against both sides of the Larsen steel sheet pile, thereby reducing the friction between the Larsen steel sheet pile and the guide member and reducing the possibility of damage to the Larsen steel sheet pile.

[0013] Optionally, another of the connecting blocks is provided with an identical guide member, and the two guide members are mirror-imaged with respect to the connecting block.

[0014] By adopting the above technical solution, the two guide members are symmetrically arranged, which can increase the contact area with the ground and provide more support points, thereby improving the stability of the guide members and reducing the possibility of tilting of the Larsen steel sheet piles during the insertion process. At the same time, since adjacent Larsen steel sheet piles need to be engaged, the adjacent Larsen steel sheet piles are oriented in opposite directions. The symmetrical arrangement of the two guide members can quickly adapt to the insertion and guiding work of adjacent Larsen steel sheet piles, thereby improving work efficiency.

[0015] Optionally, a positioning assembly is provided between the two first guide plates, and the positioning assembly includes a support plate, and the support plate is simultaneously connected to the ends of the two first guide plates.

[0016] By adopting the above technical solution, the support plate is connected to the first guide plate of the two guide members, thereby improving the stability of the guide members and increasing the supporting area, thereby improving the supporting effect.

[0017] Optionally, the positioning assembly further includes a positioning spring, one end of which is connected to the rotating rod, and the other end of which is connected to the support plate.

[0018] By adopting the above technical solution, the positioning spring connects the support plate and the rotating rod. When the support plate and the rotating rod rotate relative to each other, the positioning spring deforms and hinders the relative rotation of the two, thereby reducing the possibility of tilting of the Larsen steel sheet pile and also correcting the tilt of the Larsen steel sheet pile.

[0019] Optionally, a reinforcement assembly is provided between the support plate and the rotating rod, the reinforcement assembly includes a moving block threadedly connected to the rotating rod, the moving block is also slidably connected to the support plate, a first reinforcement block and a second reinforcement block are provided on the support plate, the first reinforcement block and the second reinforcement block are located at both ends of the moving block and on both sides of the moving block, the first reinforcement block and the second reinforcement block are both set to be inclined toward one end of the moving block, and the inclined surface is inclined downward close to the side of the moving block.

[0020] By adopting the above technical solution, when the rotating rod rotates relative to the connecting block, the moving block is driven to translate, and at the same time the moving block abuts against the first reinforcement block along the moving direction, and by squeezing the first reinforcement block, resistance is applied to the support plate to prevent the support plate from rotating relative to the rotating rod. Similarly, the moving block can hinder the reverse rotation of the rotating rod and the connecting block by squeezing the second reinforcement block, thereby improving the stability of the guide support for the Larsen steel sheet pile and improving the insertion accuracy of the Larsen steel sheet pile.

[0021] Optionally, an angle sensor is provided between the rotating rod and the connecting block, the angle sensor is electrically connected to a controller, and the controller is also electrically connected to an alarm.

[0022] By adopting the above technical solution, when the rotating rod and the connecting block rotate relative to each other, the angle sensor transmits the rotation angle signal to the controller. When the inclination angle of the Larsen steel sheet pile exceeds the range of plus or minus 2°, the controller controls the alarm to alarm, monitor and remind the inclination of the Larsen steel sheet pile.

[0023] In the second aspect, the present application provides a Larsen steel sheet pile driving inclination detection method using the following technical solution:

[0024] A detection method for a Larsen steel sheet pile driving inclination detection device comprises the following steps:

[0025] S100: The guide is positioned and installed on the ground;

[0026] S110: The fixing rod is inserted into the ground until the supporting plate abuts against the ground;

[0029] S400: Adjust the inclination angle of Larsen steel sheet piles;

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1.

[0039] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0040] A Larsen steel sheet pile driving inclination detection device, referring to Figure 1 and Figure 2 , including a connecting block 1, guide members 2 are arranged on both sides of the connecting block 1, and the two guide members 2 are arranged in a mirror image with respect to the connecting block 1. A rotating rod 3 passing through the connecting block 1 is arranged between the two guide members 2, the rotating rod 3 is rotatably connected to the connecting block 1, and the rotating rod 3 is parallel to the symmetric center line of the two guide members 2.

[0041] The end of the rotating rod 3 outside the connecting block 1 is fixedly connected to the fixing rod 4, the fixing rod 4 is perpendicular to the rotating rod 3, and the end of the fixing rod 4 away from the rotating rod 3 is set to be tapered. A pointer 41 is fixed to the end of the fixing rod 4 fixedly connected to the rotating rod 3, and the side of the connecting block 1 facing the fixing rod 4 is provided with scales 31 evenly distributed around the rotating rod 3, and the pointer 41 faces the scales 31.

[0042] The fixing rod 4 is vertically inserted at a predetermined location until the two guide members 2 are simultaneously in contact with the ground. The Larsen steel sheet pile 7 is hoisted above the guide member 2. The lower end of the Larsen steel sheet pile 7 is inserted into the guide member 2. During the insertion process, the Larsen steel sheet pile 7 drives the guide member 2 and the connecting block 1 to rotate synchronously, causing relative rotation between the connecting block 1 and the rotating rod 3. At this time, the change of the pointer 41 on the scale 31 is the inclination of the Larsen steel sheet pile 7.

[0043] The guide member 2 includes a first guide plate 21 and a second guide plate 22 which are arranged opposite to each other. One side of the first guide plate 21 is fixedly connected to the connection block 1, and the other side faces the second guide plate 22. One end of the first guide plate 21 close to the connection block 1 is fixedly connected to one end of the second guide plate 22, and the other end of the first guide plate 21 is arranged in parallel with the other end of the second guide plate 22, and the first guide plate 21 and the second guide plate 22 are both parallel to the Larsen steel sheet pile 7 and have similar shapes. When the Larsen steel sheet pile 7 is inserted into the guide member 2, the end of the Larsen steel sheet pile 7 is inserted between the first guide plate 21 and the second guide plate 22, and one side of the Larsen steel sheet pile 7 abuts against the connection between the first guide plate 21 and the second guide plate 22, and the other side is engaged with the adjacent Larsen steel sheet pile 7.

[0044] A plurality of uniform rollers are installed on the opposite sides of the first guide plate 21 and the second guide plate 22, and the edges of the rollers abut against the side walls of the Larsen steel sheet pile 7. The rollers are not shown in the figure. The rollers reduce the friction between the Larsen steel sheet pile 7 and the guide member 2, making it easier to drive the Larsen steel sheet pile 7.

[0045] A positioning assembly 5 is provided between the two guide members 2. The positioning assembly 5 includes a support plate 51 located between the two first guide plates 21. The support plate 51 is perpendicular to the two first guide plates 21 and is fixedly connected to the lower ends of the two first guide plates 21. When the lower ends of the first guide plates 21 abut against the ground, the support plate 51 abuts against the ground at the same time. An arc plate 52 is provided between the upper ends of the two first guide plates 21 to connect the two. The rotating rod 3 is located between the support plate 51 and the arc plate 52. A fixed plate 53 is fixedly connected to one end of the support plate 51 and the arc plate 52 away from the connecting block 1, and the end of the rotating rod 3 is rotatably connected to the fixed plate 53.

[0046] When the Larsen steel sheet pile 7 abuts against the arc plate 52, the Larsen steel sheet pile 7 can slide along the arc plate 52 to between the first guide plate 21 and the second guide plate 22, which facilitates the plug-in fit of the Larsen steel sheet pile 7. At the same time, the support plate 51 increases the contact area between the guide member 2 and the ground, thereby improving the stability of the guide member 2 and reducing the possibility of the guide member 2 tilting, thereby improving the guiding accuracy.

[0047] Reference Figure 1 and Figure 3 The positioning assembly 5 also includes a fixed block 54 fixed on both sides of the rotating rod 3, and a positioning spring 55 is provided between the fixed block 54 and the support plate 51. One end of the positioning spring 55 is fixedly connected to the fixed block 54 on one side of the rotating rod 3, and the other end of the positioning spring 55 is located on the other side of the rotating rod 3 and fixedly connected to the support plate 51, so that the positioning springs 55 connected to the two fixed blocks 54 are cross-distributed.

[0048] The positioning spring 55 automatically adjusts and corrects the relative position of the rotating rod 3 and the guide member 2. When the guide member 2 and the rotating rod 3 rotate relative to each other, the positioning spring 55 plays a role of blocking and restoring, thereby improving the stability and accuracy of the insertion of the Larsen steel sheet pile 7.

[0049] Reference Figure 3 and Figure 4 A reinforcing assembly 6 is also provided between the rotating rod 3 and the supporting plate 51. The reinforcing assembly 6 includes a moving block 61. One end of the moving block 61 is threadedly connected to the rotating rod 3, and the other end of the moving block 61 is slidably connected to the supporting plate 51. A sliding groove 511 parallel to the rotating rod 3 is provided on the supporting plate 51. The end of the moving block 61 away from the rotating rod 3 is inserted into the sliding groove 511 and slides along the sliding groove 511. A first reinforcing block 62 and a second reinforcing block 63 are fixed in the sliding groove 511. The first reinforcing block 62 and the second reinforcing block 63 have a certain elasticity. The first reinforcing block 62 and the second reinforcing block 63 are located at both ends of the moving block 61, and the first reinforcing block 62 and the second reinforcing block 63 are located on both sides of the sliding groove 511. The ends of the first reinforcing block 62 and the second reinforcing block 63 close to the moving block 61 are set as inclined surfaces, and the side of the inclined surface away from the moving block 61 gradually moves away from the bottom of the sliding groove 511.

[0050] When the guide member 2 rotates clockwise relative to the rotating rod 3, the moving block 61 moves toward the first reinforcement block 62 and presses against the inclined surface of the first reinforcement block 62, thereby the moving block 61 applies pressure to the first reinforcement block 62, and the pressure drives the guide member 2 to rotate counterclockwise relative to the rotating rod 3, thereby enhancing the stability of the guide member 2 and reducing the inclination of the Larsen steel sheet pile 7. Similarly, when the moving block 61 moves toward the second reinforcement block 63, the pressure applied by the moving block 61 to the second reinforcement block 63 prevents the guide member 2 from rotating counterclockwise relative to the rotating rod 3.

[0051] In order to improve the monitoring accuracy of the inclination of the Larsen steel sheet pile 7, an angle sensor connecting the rotating rod 3 and the connecting block 1 is installed between the two, and the angle sensor is electrically connected to the controller, and the controller is also electrically connected to the alarm, wherein the angle sensor, the controller and the alarm are not shown in the figure. When the angle sensor detects that the relative rotation angle between the rotating rod 3 and the connecting block 1 exceeds 2°, the angle sensor transmits a signal to the controller, and the controller controls the alarm to alarm, and promptly reminds to adjust the inclination of the Larsen steel sheet pile 7, thereby improving the construction accuracy of the Larsen steel sheet pile 7.

[0053] S100: The guide member 2 is positioned and installed on the ground;

[0054] S110: The fixing rod 4 is inserted into the ground, and the end of the rotating rod 3 is directed toward the previous Larsen steel sheet pile 7 that has been inserted and driven, until the supporting plate 51 abuts against the ground;
