Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe pile construction, and more particularly to a steel pipe pile construction device for a steel trestle in a shallow overburden deep water. BACKGROUND

[0002] Steel pipe pile construction for a steel trestle refers to the process of using steel pipe piles as the main support structure during the construction of a steel trestle. Steel pipe piles are widely used in bridge construction due to their high bearing capacity, good seismic performance, ease of construction, and economy, especially in deep water, soft soil foundations, or complex geological conditions.

[0003] Current steel pipe pile construction for a steel trestle usually uses a caterpillar crane to cooperate with a vibration hammer to drive the steel pipe pile. The caterpillar crane is parked on the completed bridge deck of the temporary bridge, and the steel pipe pile is driven into the foundation of the temporary bridge. After the pile position and the verticality of the pile are determined to meet the requirements, the vibration hammer is started to vibrate and the steel pipe pile is lowered. In the prior art, in order to ensure the verticality of the steel pipe pile during lowering, an underwater robot carrying a camera device is used to detect the inclination during the lowering of the steel pipe pile. However, for complex underwater environments, the underwater robot is prone to damage, and the cost of the underwater robot is relatively high. Therefore, for complex underwater environments, a guide cylinder is usually used to guide the steel pipe pile. In the early stage of the sinking of the steel pipe pile, the guide cylinder can help maintain the verticality of the pile body and prevent it from deviating. In addition, the vibration hammer generates strong vibrations during operation, which are transmitted to the steel pipe pile. In order to avoid transmitting the vibration of the steel pipe pile to the guide cylinder during lowering, affecting the stability of the guide frame, or even causing it to deviate or be damaged, the steel pipe pile needs to be located in the guide cylinder without contact between the steel pipe pile and the inner wall of the guide cylinder during the lowering of the guide cylinder.

[0004] However, during the lowering of the steel pipe pile, due to the shallow overburden deep water position, the soil in the shallow overburden is usually soft and has a high water content, and the physical and mechanical properties of the soil in the shallow overburden are poor, with limited bearing capacity. When the steel pipe pile is driven, the soil may not be able to provide sufficient support, which can easily cause the steel pipe pile to sink unstably and deviate or tilt. When the steel pipe pile tilts, the steel pipe pile is easily squeezed into the guide cylinder due to its large weight, causing deformation and damage to the steel pipe pile and affecting the guiding effect of the guide cylinder.

DETAILED DESCRIPTION ​​

[0031] The application will be described in further detail below with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the application and cannot be understood as limiting the scope of protection of the application. Those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0032] With reference to the description accompanying drawings Figures 1 to 5 A shallow cover deep water steel trestle steel pipe pile construction device, comprising: a guide cylinder 1 and a steel pipe pile 7, the steel pipe pile 7 is located in the inner side of the guide cylinder 1, the guide cylinder 1 is used for guiding the steel pipe pile 7 when piling, the guide cylinder 1 is installed with a mounting mechanism 2, the mounting mechanism 2 is used for fastening and fixing the guide cylinder 1;

[0033] The guide cylinder 1 is provided with an inclination detection mechanism 3, the inclination detection mechanism 3 comprises a plurality of transversely sliding slide shafts 31 and a trigger alarm assembly, the plurality of slide shafts 31 are transversely arranged, the steel pipe pile 7 is located between the plurality of slide shafts 31, and the plurality of slide shafts 31 are uniformly distributed in the circumferential direction of the steel pipe pile 7, the inclination detection mechanism 3 is pressed by the steel pipe pile 7 to touch the trigger alarm assembly to detect the inclination state of the steel pipe pile 7 and issue an alarm.

[0034] It should be noted that the mounting mechanism 2 can be fixedly installed on the initially built steel trestle, if the steel trestle is initially built, a temporary platform can be temporarily built on the shore, the mounting mechanism 2 is fixed on the temporarily built platform to realize the stable fixation of the guide cylinder 1, the trigger alarm assembly can be an infrared sensor, an alarm and a controller, when the steel pipe pile 7 is inclined, the steel pipe pile 7 will contact the slide shaft 31 and extrude the slide shaft 31 to slide, at this time, the movement of the slide shaft 31 is monitored by the infrared sensor, so that the signal can be transmitted to the controller through the infrared sensor, and the alarm is driven by the controller to issue an alarm to remind the operator that the steel pipe pile 7 is inclined.

[0035] It should be further noted that in the initial state, there is a certain distance between the steel pipe pile 7 and the end of the slide shaft 31, which is the allowable inclination error of the steel pipe pile 7.

[0036] The implementation scene is specifically: first, the guide cylinder 1 is stably fixed through the mounting mechanism 2, then the steel pipe pile 7 is lowered through the crawler crane and the vibration hammer, in the initial stage of lowering, the steel pipe pile 7 is guided through the guide cylinder 1, when the steel pipe pile 7 is lowered to the shallow overburden layer deep water through the vibration hammer, because the physical and mechanical properties of the shallow overburden layer soil are poor, the bearing capacity is limited, at this time, if the steel pipe pile 7 is inclined, when the steel pipe pile 7 is inclined, the steel pipe pile 7 will contact and extrude the sliding shaft 31 to slide, at this time, the movement of the sliding shaft 31 is monitored through the infrared sensor, so that the signal can be transmitted to the controller through the infrared sensor, and the alarm is driven by the controller to issue an alarm to remind the operator that the steel pipe pile 7 is inclined, so that the operator can stop operation and correct the steel pipe pile in time.

[0037] Further, referring to the drawings attached to the specification Figures 3 to 5 The trigger alarm assembly includes a moving contact 32, a stationary contact 34 and a buzzer 35, the end of each of the plurality of sliding shafts 31 is provided with a moving contact 32, and each of the plurality of sliding shafts 31 is provided with an elastic member 33, the elastic member 33 is used for the reset movement of the sliding shaft 31, and the moving contact 32, the stationary contact 34 and the buzzer 35 are electrically connected.

[0038] It should be noted that the elastic member 33 is a spring, which is used to extrude the spring when the sliding shaft 31 slides after the steel pipe pile 7 is inclined, and after the steel pipe pile 7 is corrected, the sliding shaft 31 can be reset under the elastic deformation of the spring, the stationary contact 34 is annularly arranged, when the steel pipe pile 7 is inclined, the steel pipe pile 7 extrudes the sliding shaft 31 to move, so that the sliding shaft 31 drives the moving contact 32 to move and contact the stationary contact 34 to power the buzzer 35, so that the buzzer 35 can issue an alarm to remind the operator that the steel pipe pile 7 is inclined and needs to be corrected immediately.

[0039] Further, referring to the drawings attached to the specification Figure 4 The moving contact 32 includes a connecting seat 321, a contact 322 and a buffer 323, the connecting seat 321 is fixedly arranged at the end of the sliding shaft 31, the contact 322 is slidably arranged in the connecting seat 321, and the buffer 323 is arranged between the contact 322 and the connecting seat 321.

[0040] It should be noted that the buffer 323 is a spring, when the contact 322 contacts the stationary contact 34, because the machine has not been stopped at this time, the steel pipe pile 7 may continue to be inclined during the piling process through the vibration hammer, the contact 322 is buffered through the spring, which can avoid excessive extrusion and damage to the contact 322 and the stationary contact 34.

[0041] In the above technical scheme, the inclination detection mechanism 3 is arranged to detect the inclination of the steel pipe pile 7 during the pile driving process of the steel pipe pile 7, but when the steel pipe pile 7 is lowered, the steel pipe pile 7 needs to be in the central position of the guide cylinder 1, so as to detect the inclination of the steel pipe pile 7. If the steel pipe pile 7 is not in the central position of the guide cylinder 1 during the initial lowering of the steel pipe pile 7, the distance between the steel pipe pile 7 and each sliding shaft 31 is different, so it is difficult to accurately detect the inclination of the steel pipe pile 7. Therefore, the present application provides a guide mechanism 4 for guiding the steel pipe pile 7 during the initial lowering of the steel pipe pile 7, so that the steel pipe pile 7 is in the central position of the guide cylinder 1.

[0042] Specifically, referring to the description of the drawings Figure 6 and Figure 7 , the guide cylinder 1 is provided with a guide mechanism 4, the guide mechanism 4 includes three rollers 41 which can move synchronously, and the three rollers 41 are uniformly distributed in the circumferential direction. During the initial lowering of the steel pipe pile 7, the guide mechanism 4 makes the three rollers 41 contact the outer wall of the steel pipe pile 7, so that the steel pipe pile 7 is in the central position of the guide cylinder 1. The guide mechanism 4 further includes a power component 43 which is installed on the guide cylinder 1, and each of the three rollers 41 is fixedly provided with a moving frame 42, and the output end of the power component 43 is fixedly connected with one of the moving frames 42. Each of the three moving frames 42 is provided with a slot 421, and the guide cylinder 1 is rotatably provided with a disc 45, and the disc 45 is provided with three circular shafts 44 which are slidably arranged in the corresponding slots 421.

[0043] It should be noted that the power component 43 is a pneumatic cylinder. During the initial lowering of the steel pipe pile 7, the pneumatic cylinder pushes one of the moving frames 42 to move towards the central position of the guide cylinder 1, so that the moving frame 42 drives the corresponding roller 41 to move towards the central position of the guide cylinder 1. At this time, through the cooperation of the circular shaft 44 and the slot 421, the disc 45 can be rotated, so that the three rollers 41 can be synchronously moved towards the central position of the guide cylinder 1. Thus, when the steel pipe pile 7 is lowered, the three rollers 41 can contact the outer wall of the steel pipe pile 7, so that the steel pipe pile 7 can be in the central position of the guide cylinder 1 during the lowering.

[0044] It should be further noted that the guide mechanism 4 can be longitudinally arranged in the guide cylinder 1, so that the steel pipe pile 7 can be kept in a vertical state during the lowering.

[0045] It should be further noted that after the guide mechanism 4 is used to guide the steel pipe pile 7 during the initial lowering of the steel pipe pile 7, in order to avoid the vibration of the steel pipe pile 7 caused by the pile driving of the vibration hammer from being transmitted to the guide cylinder 1 and affecting the stability of the guide cylinder 1, the moving reset roller 41 needs to be driven after the initial lowering.

[0046] When the steel pipe pile 7 is inclined during the process of piling down, the piling needs to be stopped immediately, and the steel pipe pile 7 needs to be corrected, therefore, the application provides a correction mechanism 5, which corrects the steel pipe pile 7 when the steel pipe pile 7 is inclined.

[0047] Specifically, referring to the drawings Figure 8 And Figure 9 The guide cylinder 1 is provided with the correction mechanism 5, the correction mechanism 5 comprises a fixed seat 51, the fixed seat 51 is installed on the guide cylinder 1, the fixed seat 51 is provided with a support 52 which rotates, the support 52 is fixedly provided with a power component two 53, the output end of the power component two 53 is installed with a correction plate 54, the correction mechanism 5 further comprises a rotary drive assembly 55, the rotary drive assembly 55 comprises a power component three 551, the output end of the power component three 551 is installed with a driving gear 552, the fixed seat 51 is provided with a gear ring 553 which rotates, the driving gear 552 is engaged with the gear ring 553, and the gear ring 553 is fixedly connected with the support 52.

[0048] It should be noted that the power component two 53 is a cylinder, the power component three 551 is a motor, the correction plate 54 is driven by the cylinder to move towards the steel pipe pile 7, so that the correction plate 54 pushes the steel pipe pile 7 to correct the inclination, and the driving gear 552 is driven by the motor to rotate, so that the driving gear 552 drives the gear ring 553 to rotate, and then the support 52 is driven to rotate, so that the position of the correction plate 54 is adjusted according to the inclination direction of the steel pipe pile 7 to correct the inclination.

[0049] Further, referring to the drawings Figure 2 The mounting mechanism 2 comprises a cross frame 21, the cross frame 21 is fixedly arranged on one side of the guide cylinder 1, the end of the cross frame 21 is fixedly provided with a support steel 22, the bottom of the support steel 22 is provided with a fastener 23, and the fastener 23 is used for being fixed on the initially built steel trestle.

[0050] It should be noted that the fastener 23 can be an anchor bolt, and the guide cylinder 1 can be fastened and mounted on the initially built steel trestle or the temporarily built platform on the shore through the anchor bolt, the support steel 22 and the cross frame 21.

[0051] However, in the above technical solution, after the inclined steel pipe pile 7 is corrected, the inclined state position of the steel pipe pile 7 cannot be controlled, so that the steel pipe pile 7 will appear two situations after the correction, one is that the steel pipe pile 7 is corrected and is in the center position of the guide cylinder 1, and the other is that the steel pipe pile 7 is not in the center position of the guide cylinder 1 after the correction, such as Figure 10As shown, the steel pipe pile 7 is not in the center position of the guide cylinder 1 after the deviation correction, and the steel pipe pile 7 needs to be piled and lowered, and if the steel pipe pile 7 is not in the center position of the guide cylinder 1, it is difficult to continue to accurately detect the inclination of the steel pipe pile 7, therefore, the adjusting mechanism 6 is used to adjust the position of the guide cylinder 1 when the steel pipe pile 7 is not in the center position of the guide cylinder 1 after the deviation correction of the steel pipe pile 7, so that the steel pipe pile 7 is in the center position of the guide cylinder 1.

[0052] Specifically, referring to the description attached Figure 10 And Figure 11 The adjusting mechanism 6 is arranged on the support steel 22, the adjusting mechanism 6 includes linear drive assembly one 61 and linear drive assembly two 62, the adjusting mechanism 6 adjusts the position of the guide cylinder 1 through the linear drive assembly one 61 and the linear drive assembly two 62, the linear drive assembly one 61 includes a support seat one 611, the support seat one 611 is installed on the support steel 22, the support seat one 611 is fixedly installed with a power component four 612, the output end of the power component four 612 is installed with a lead screw one 613, the support seat one 611 is slidably provided with a sliding seat one 614, the sliding seat one 614 is threadedly connected with the lead screw one 613, the linear drive assembly two 62 includes a support seat two 621, the support seat two 621 is fixedly installed on the sliding seat one 614, the support seat two 621 is fixedly provided with a power component five 622, the output end of the power component five 622 is installed with a lead screw two 623, the support seat two 621 is slidably provided with a sliding seat two 624, the sliding seat two 624 is threadedly connected with the lead screw two 623, and the cross frame 21 is fixedly arranged on the sliding seat two 624.

[0053] It should be noted that the power component four 612 and the power component five 622 are motors, the lead screw one 613 is driven to rotate by the power component four 612, so that the sliding seat one 614 can move linearly under the thread cooperation of the lead screw one 613 and the sliding seat one 614, and the lead screw two 623 is driven to rotate by the power component five 622, so that the sliding seat two 624 can move linearly under the thread cooperation of the lead screw two 623 and the sliding seat two 624, so that the cross frame 21 can drive the guide cylinder 1 to move, so as to adjust the position of the guide cylinder 1.

[0054] It should be noted that since the steel pipe pile 7 is piled and lowered by the vibration hammer, the bottom end of the steel pipe pile 7 has been driven into the soil under the deep water at this time, so the position of the steel pipe pile 7 cannot be moved at this time, and only the position of the guide cylinder 1 can be adjusted.

[0055] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the protection scope of the present application.
