Description

[0002] In the process of geotechnical engineering foundation treatment, a rammer reinforcement device is required to compact the foundation. The hydraulic rammer is a new type of foundation compaction and reinforcement processing mechanical equipment. The hydraulic cylinder in the frame drives the rammer to repeatedly rise and fall to hammer the lower rammer plate, thereby realizing the compaction of the foundation soil through the rammer plate.

The compaction effect and efficiency are easily affected by the looseness and sinking depth of the foundation soil; 2. It is difficult to unify the compaction treatment intervals during the compaction process. Intervals that are too close or too far will reduce the effective compaction efficiency; 3.

[0015] Beneficial effects of the present invention:

[0016] The tamping reinforcement device for geotechnical engineering foundation treatment of the present invention can realize the adjustment of the tamping plate position within the stroke according to the construction requirements through the unique structural design of the tamping plate carrying structure at the bottom of the tamping treatment mechanism. During the foundation treatment construction process, the front mechanical arm of the construction vehicle is required to adjust the frame height due to the influence of the looseness of the ground and the depth of the subsidence, so as to realize the compaction of the foundation with a larger subsidence depth. The method of only adjusting the frame height by the front mechanical arm so as to keep the tamping plate in contact with the ground is not only energy-consuming, but also easily affected by the terrain. For example, if the construction vehicle is at a high point and the foundation to be compacted is at a low point, the machine If the mechanical arm has driven the frame to a low position for compaction, the tamping plate will not be able to transmit pressure to the foundation efficiently, and may even be in a suspended state due to the influence of the sinking depth, posing a construction hazard. In this device, each set of lifting control motors can be used to drive the lifting screw to rotate, thereby driving the tamping plate carrier to slide downward through the threaded transmission end block, and supporting and buffering the inner wall of the transmission buffer groove through the limit buffer end block and the upper elastic buffer rubber pad, thereby achieving downward adjustment of the tamping plate position to maintain pressure contact with the foundation surface, thereby reducing the problem of the construction efficiency and compaction effect being affected by the foundation construction environment during the compaction and reinforcement process;

[0017] The ramming reinforcement device for geotechnical engineering foundation treatment of the present invention is provided with a ramming plate carrying structure with adjustable depth in the ramming treatment mechanism in conjunction with a ramming hammer connecting structure, which can achieve that after the ramming plate position is adjusted, the ramming hammer can still maintain effective hammering transmission to it and reduce the impact feedback to the oil cylinder to increase the service life. The extended-range buffer cylinder seat is slidably mounted in the ramming hammer body through the damping sliding cavity, and the hydraulic oil pump end is slidably arranged in the extended-range buffer cavity. Therefore, in the process of the hydraulic oil pump driving the ramming hammer body to descend, the hydraulic oil pump end slides in the extended-range buffer cavity. Therefore, when the ramming hammer body collides with the ramming plate body, the collision pressure transmission to the hydraulic oil pump can be reduced through the sliding buffer, and in conjunction with The buffer sliding cavity at the bottom of the rammer body, the buffer piston plate and the buffer support spring, the rammer plate buffer column at the top of the rammer plate body and the multiple groups of buffer shock-absorbing pads can greatly reduce the collision pressure transmission to the hydraulic oil pump and increase the service life of the hydraulic oil pump. At the same time, the sliding arrangement of the hydraulic oil pump end is in the extended-range buffer cavity, and the rammer plate mounting seat can slide downward and adjust to keep the rammer plate body in contact with the foundation surface. When the rammer plate mounting seat is placed in the downward depth adjustment position, the rammer body can increase the downward sliding hammering depth through the extended-range buffer cavity, thereby achieving the effect of maintaining the rammer body to achieve effective hammering transmission to the rammer plate body as the depth of the rammer plate body is adjusted;

[0018] The ramming reinforcement device for geotechnical engineering foundation treatment of the present invention can reduce the force borne by the mechanical arm of the construction vehicle and reduce the dust during the ramming process through the outer wall structure of the ramming treatment mechanism, and determine and pre-process the next ramming point. An extended edge portion is provided on the outer side of the treatment carrier. The extended edge portion can achieve a certain support effect by the bottom of the extended edge portion contacting with the upper surface of the foundation pit body during the ramming and sinking process, thereby reducing the force borne by the mechanical arm, and at the same time, the ramming plate body is driven by the ramming plate carrier to set an adjustable depth effect to maintain the pressure contact between the ramming plate body and the bottom wall of the foundation pit body to maintain the ramming effect. The extended edge portion forms a support effect on the upper surface of the pit bottom and has a certain sealing effect on the pit bottom, thereby greatly reducing the problem of a large amount of dust flying due to vibration in the pit during the ramming process, and at the extended edge portion The front side rotates and carries an auxiliary carrying plate, which is driven by an auxiliary hydraulic pump from a retracted state to a horizontal state, so that during the compaction process, the auxiliary compaction plate and the front side of the compaction plate body can realize the determination and pretreatment effect of the next compaction point. The auxiliary compaction plate is fitted to the point to be compacted through multiple sets of supporting slide columns and supporting spring structures, and in the process of the rammer body hammering the rammer body, the kinetic energy transmitted by the frame is effectively used to press down the point to be compacted with a certain force. At the same time, as the sinking depth of the point being compacted increases, the elastic support force of the support spring gradually increases, so that the pressure on the point to be compacted also gradually increases, thereby effectively pre-treating the point to be compacted, determining the position of the next compaction point, improving the compaction processing efficiency and improving the construction accuracy, and avoiding the problem of inconsistent, too close, or too far compaction points resulting in a decrease in compaction effect.

[0037] Specific use of the present invention:

[0038] When loading is in use, the loading is achieved by fixing the front end of the construction vehicle with the corresponding hole groove structure and the end of the frame mounting plate 14 in combination with the bolt structure. During use, the hydraulic oil pump 19 controls the rammer body 40 in the rammer lifting chamber 11 to reciprocate and lift the rammer plate body 46 to hammer the ground to compact and reinforce it.

[0039] In a ramming reinforcement device for geotechnical engineering foundation treatment of the present invention, the unique structural design of the ramming plate carrying structure at the bottom of the ramming treatment mechanism 15 can realize the adjustment of the ramming plate position within the stroke according to construction needs. During the foundation treatment construction process, the front mechanical arm of the construction vehicle is required to adjust the frame height due to the influence of the ground looseness and the subsidence depth, so as to realize the ramming of the foundation with a larger subsidence depth. The method of only adjusting the frame height by the front mechanical arm so that the ramming plate keeps in contact with the ground is not only energy-consuming, but also easily affected by the terrain. For example, if the construction vehicle is at a high point and the foundation to be rammed is at a low point, the mechanical arm has already driven the machine. If the frame is in a low position for compaction, the ramming plate will not be able to transmit pressure to the foundation efficiently, and may even be in a suspended state due to the influence of the sinking depth, which may cause construction hazards. In this device, the lifting screw 59 can be driven to rotate by each group of lifting control motors 43, thereby driving the ramming plate mounting seat 45 to slide downward through the threaded transmission end block 50, and supporting and buffering the inner wall of the transmission buffer groove 47 through the limit buffer end block 48 and the upper elastic buffer rubber pad 49, thereby achieving downward adjustment of the ramming plate position to maintain pressure contact with the foundation surface, thereby reducing the problem that the construction efficiency and compaction effect are affected by the foundation construction environment during the compaction and reinforcement process;

[0040] In a ramming reinforcement device for geotechnical engineering foundation treatment of the present invention, a ramming plate carrying structure with adjustable depth is arranged in conjunction with a ramming hammer connecting structure in the ramming processing mechanism 15, so that after the ramming plate position is adjusted, the ramming hammer can still maintain effective hammering transmission to it and reduce the impact feedback on the oil cylinder to increase the service life. The extended-range buffer cylinder seat 35 is slidably mounted in the ramming hammer body 40 through the shock-absorbing sliding cavity 41, and the end of the hydraulic oil pump 19 is slidably arranged in the extended-range buffer cavity 36. Therefore, in the process of the hydraulic oil pump 19 driving the ramming hammer body 40 to descend, the end of the hydraulic oil pump 19 slides in the extended-range buffer cavity 36. Therefore, when the ramming hammer body 40 collides with the ramming plate body 46, the collision pressure transmission to the hydraulic oil pump 19 can be reduced through the sliding buffer, and in conjunction with the ramming hammer body 40 The bottom buffer sliding cavity 54, the buffer piston plate 55 and the buffer support spring 56, the ramming plate buffer column 53 on the top of the ramming plate body 46 and the multiple groups of buffer shock-absorbing pads can greatly reduce the collision pressure transmission to the hydraulic oil pump 19 and increase the service life of the hydraulic oil pump 19. At the same time, the end sliding of the hydraulic oil pump 19 is set in the extended-range buffer cavity 36, and the ramming plate mounting seat 45 can be adjusted to slide downward so that the ramming plate body 46 keeps contacting the foundation surface. When the ramming plate mounting seat 45 is placed in the downward depth adjustment position, the ramming hammer body 40 can increase the downward sliding hammering depth through the extended-range buffer cavity 36, thereby achieving the effect of maintaining the ramming hammer body 40 to effectively transmit the hammering to the ramming plate body 46 as the depth adjustment is set for the ramming plate body 46;

[0041] The ramming reinforcement device for geotechnical engineering foundation treatment of the present invention can reduce the force borne by the construction vehicle mechanical arm and reduce the dust during the ramming process through the outer wall structure setting of the ramming processing mechanism 15, and determine and pre-process the next ramming point. An extended edge portion 31 is provided on the outer side of the processing carrier 30. The extended edge portion 31 can achieve a certain support effect during the ramming sinking process by the bottom of the extended edge portion 31 contacting the upper surface of the foundation pit body to form a certain support effect, thereby reducing the force borne by the mechanical arm, and at the same time, the ramming plate carrier 45 drives the ramming plate body 46 to set a depth-adjustable effect to keep the ramming plate body 46 in pressure contact with the bottom wall of the foundation pit body to maintain the ramming effect. The extended edge portion 31 forms a support effect on the upper surface of the pit bottom and has a certain sealing effect on the pit bottom, thereby greatly reducing the problem of a large amount of dust flying due to vibration in the pit during the ramming process. The auxiliary carrying plate 20 is rotated sideways and driven by the auxiliary hydraulic pump 18 to be placed from the retracted state to the horizontal state, so that during the compaction process, the next compaction point can be determined and the pretreatment effect can be achieved through the auxiliary compaction plate 21 and the front side of the compaction plate body 46. The auxiliary compaction plate 21 is fitted to the point to be compacted through multiple groups of supporting slides 25 and supporting springs 27 structures, and in the process of the rammer body 40 hammering the rammer body 46, the kinetic energy transmitted by the frame is effectively utilized to press down the point to be compacted with a certain force. At the same time, as the sinking depth of the point being compacted increases, the elastic support force of the support spring 27 gradually increases, so that the pressure on the point to be compacted also gradually increases, thereby effectively pre-treating the point to be compacted, determining the position of the next compaction point, improving the compaction processing efficiency and improving the construction accuracy, and avoiding the problem of inconsistent, too close, or too far compaction points leading to a decrease in compaction effect.

Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention.
