Description

Technical Field

[0001] The utility model relates to the technical field of inclined pile construction equipment, in particular to an inclined static pressure pile equipment. Background Art

[0002] With the vigorous promotion and application of foundation pit inclined support piles, or inclined supports, inclined pile driving equipment has attracted more and more attention from technical personnel in the industry.

[0003] Compared with pile drivers and vibrating pile drivers, static pile drivers such as inclined static pile driving equipment have the characteristics of low vibration and low noise. The existing inclined static pile driving equipment generally includes a chassis or base of a main machine supported on the construction floor surface, and the chassis generally includes a construction platform and a walking mechanism.

[0004] A static pressure pile device or static pressure pile mechanism is provided at one end of the construction platform. The static pressure pile device is in an inclined state with the outer end higher and the inner end lower. Counterweights are generally provided on both sides of the static pressure pile device, and counterweights are also generally provided on both sides of the other end of the construction platform.

[0005] The walking mechanism, such as the crawler-type walking mechanism, includes a longitudinal movement mechanism and a transverse movement mechanism. For example, there is a longitudinal movement mechanism under each of the front and rear sides of the construction platform, and there is a transverse movement mechanism under each of the left and right ends of the construction platform. The transverse movement mechanism is also called a long boat, and the longitudinal movement mechanism is also called a short boat. The long boat and the short boat are also collectively referred to as roadbed plates, such as four roadbed plates. The long boat under the construction platform at one end of the static pressure pile driving device can be called the first long boat, and the long boat under the construction platform at the other end can be called the second long boat. The first long boat is provided with a first transverse slide rail and a first hydraulic cylinder for driving the construction platform to move laterally and linearly, and the second long boat is provided with a second transverse slide rail and a second hydraulic cylinder for driving the construction platform to move laterally and linearly. It is not difficult to understand that the first hydraulic cylinder and the second hydraulic cylinder act synchronously to drive the construction platform to move forward or backward laterally.

[0006] However, the inclined static pressure pile equipment of the prior art still has the following shortcomings: when pressing inclined piles or planted inclined piles such as pipe piles on soft soil foundations such as soft mud layers near the ground, sometimes hard soil or local rocks may be encountered and the inclined static pressure pile equipment cannot be pressed down and needs to be drilled and pressed down again. In this case, the entire inclined static pressure pile equipment can only be moved away by a walking walking mechanism, and then an inclined drilling pile machine or drilling machine is moved by the walking walking mechanism, and the pile machine is moved away after drilling from the center hole of the pipe pile, and then the inclined static pressure pile equipment is moved back to continue pressing the inclined pile; or when encountering a harder soil layer, a section of hole needs to be drilled first, and then a section of pile needs to be pressed, and then a hole needs to be drilled from the center hole of the pipe pile, and then the inclined pile needs to be pressed. Regardless of whether drilling a hole first or pressing a pile first, the inclined drilling machine and the inclined static pressure pile equipment are moved back and forth by the walking walking mechanism, and the axis of the inclined hole needs to be re-aligned each time, which is complicated to operate, time-consuming and labor-intensive, labor-intensive, low in construction efficiency, and high in construction cost. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide an inclined static pressure pile driving device which can realize the alternating operation of drilling inclined holes and pressing inclined piles only by moving the construction platform horizontally along the long ship, and has convenient operation and high construction efficiency.

[0008] The technical solution of the utility model is to provide an inclined static pressure pile pressure equipment, including a chassis and an inclined static pressure pile pressure device arranged at one end of the chassis, the chassis including a construction platform and a walking mechanism, the walking mechanism including a first long ship and a second long ship with a linear transverse construction platform device, the inclined static pressure pile pressure device is arranged on the construction platform above the first long ship in an inclined state with a higher outer end and a lower inner end; an inclined drilling device is arranged on an outer construction platform of the inclined static pressure pile pressure device, the axis of the drill rod of the inclined drilling device is parallel to the axis of the pile holding hole of the pile holding box of the inclined static pressure pile pressure device, and the axis of the drill rod of the inclined drilling device and the axis of the pile holding hole of the inclined static pressure pile pressure device are on the same inclined plane.

[0009] After adopting the above structure, the utility model inclined static pressure pile device has the following advantages: since an inclined drilling device is arranged on an outer side construction platform of the inclined static pressure pile device above the first long ship, no matter whether drilling or piling is performed first, the first long ship and the second long ship can be synchronously started to move horizontally, that is, move forward or backward, and since the axis of the drill rod of the inclined drilling device is parallel to the axis of the pile holding hole of the inclined static pressure pile device, and the axis of the drill rod of the inclined drilling device and the axis of the pile holding hole of the inclined static pressure pile device are on the same inclined plane, as long as the inclined drilling device or the inclined static pressure pile device is linearly moved horizontally to the upper side of the inclination of the hole position, the axis of the drill rod of the inclined drilling device or the axis of the pile holding hole of the inclined static pressure pile device can be conveniently and quickly aligned with the inclined axis of the hole or the inclined axis of the pipe pile, that is, on the same inclined straight line. No matter drilling or piling is performed first, the alternating operation of drilling inclined holes and pressing inclined piles can be realized by only moving the construction platform horizontally along the long ship, which is simple, convenient and fast to operate, saves time and effort, has low labor intensity, high construction efficiency and low construction cost.

[0010] Furthermore, the inclined drilling device includes an inclined support frame installed on the construction platform, and the inclined support frame is provided with a lifting hydraulic cylinder for driving the power head to move linearly along the inclined support frame, and the free end of the piston rod of the lifting hydraulic cylinder is hinged on the fixed plate at the top of the inclined support frame, and one end of the cylinder barrel of the lifting hydraulic cylinder is fixed to the power head. After adopting the above structure, the inclined drilling device can fully meet the needs of drilling with the inclined static pressure pile device, and has strong pertinence and adaptability, and does not require the complex structure of a large drilling rig, and its structure is simple and the equipment cost is relatively low. It further ensures the technical effects of simple, convenient and fast operation, time and labor saving, low labor intensity, high construction efficiency and low construction cost.

[0011] Furthermore, the inclined support frame has a guide structure that makes the axis of the drill rod always parallel to the axis of the inclined support frame to ensure that the axis of the drill rod is always parallel to the axis of the pile holding hole of the inclined static pressure pile device, and the axis of the drill rod and the axis of the pile holding hole of the pile holding box of the inclined static pressure pile device are always on the same inclined plane. With the above structure, the technical effect of conveniently and quickly aligning the axis of the drill rod of the inclined drilling device with the inclined axis of the hole or the inclined axis of the pile is further ensured.

[0012] Furthermore, the diagonal support frame is fixed to a fixed counterweight block on the construction platform via a support plate, and the inclined bottom surface of the diagonal support frame is fixed against an inclined surface of the counterweight block on the construction platform. After adopting the above structure, the angle between the inclined surface of the configuration block and the horizontal line and the angle between the axis of the pile hole of the inclined static pressure pile device and the horizontal line can be made the same in advance, thereby ensuring that the axis of the drill rod is always parallel to the axis of the pile hole of the inclined static pressure pile device, and the axis of the drill rod and the axis of the pile hole of the inclined static pressure pile device are always on the same inclined surface. Because the inclined drilling device is used as a drilling device supporting the inclined static pressure pile device, the actual construction needs of the inclined static pressure pile device can be met without the adjustment of the hydraulic cylinder for adjusting the inclination angle of the diagonal support frame, and the structure is relatively simple, with strong pertinence and adaptability, and does not require the complex structure of a large drilling rig, and the equipment cost is relatively low. It further ensures that the operation is simple, convenient and fast, time-saving and labor-saving, low labor intensity, high construction efficiency and low construction cost.

[0013] Furthermore, the drill rod has a detachable connection structure in which two adjacent sections are connected to each other to extend the total length of the drill rod. After adopting the above structure, the drill rod can be extended section by section according to the actual drilling depth, so that the total length of the drill rod meets the needs of actual construction, such as first drilling a section of the drill rod into the soil, then releasing the connection between it and the power head, then lifting the power head, and then connecting a new section of the drill rod with the next section of the drill rod and the power head, that is, connecting the new drill rod, and the power head rotates to drive the drill rod drill bit to continue drilling. Its structure is relatively simple, highly targeted and adaptable, and does not require the complex structure of a large drilling rig, and the equipment cost is relatively low. It further ensures that its operation is simple, convenient and fast, saving time and effort, low labor intensity, high construction efficiency, and low construction cost. Technical effects.

[0014] Furthermore, a liquid infusion pipe connecting the liquid source and pump with the nozzle on the drill bit is installed in the drill rod and on the drill bit; the liquid infusion pipe is a cement slurry infusion pipe connecting the cement slurry source and pump with the nozzle on the drill bit, or the liquid infusion pipe is a water infusion pipe connecting the water source and pump with the nozzle on the drill bit. With the above structure, the inclined static pressure pile equipment can meet the needs of grouting when drilling inclined cement soil mixing piles or high-pressure rotary jet piles, and can also meet the needs of water spraying when drilling directly inclined piles on soft soil foundations. It further ensures the technical effects of simple, convenient and fast operation, time and labor saving, low labor intensity, high construction efficiency and low construction cost.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown.

[0031] The utility model inclined static pressure pile equipment includes a chassis 1, and the chassis 1 includes a construction platform 11 and a walking mechanism such as a walking walking mechanism 12. The utility model inclined static pressure pile equipment also includes an inclined static pressure pile device 2 arranged at one end of the chassis 1, such as an inclined static pressure pile device 2 or an inclined static pressure pile mechanism is arranged at one end of the construction platform 11, and the inclined static pressure pile device 2 is in an inclined state with an outer end higher and an inner end lower. Two gantry pile frames 21 protruding upward are symmetrically arranged on both sides of the inclined static pressure pile device 2, and each gantry pile frame 21 is provided with a pile holding box 23 or a pile clamp box or a pile holding device driven by a pile pressing hydraulic cylinder 22 such as an oil cylinder and provided with a horizontal pile holding hydraulic cylinder such as an oil cylinder, and the center hole of the pile holding box 23 is a pile holding hole 231. Counterweights 13 such as a fixed counterweight block 131 are generally symmetrically arranged on both sides of the inclined static pressure pile device 2, and counterweights 13 are generally symmetrically arranged on both sides of the other end of the construction platform 11. The walking mechanism 12 includes a longitudinal movement mechanism 122 and a transverse movement mechanism, such as a longitudinal movement mechanism 122 under each of the front and rear sides of the construction platform 11, and a transverse movement mechanism under each of the left and right ends of the construction platform 11. The transverse movement mechanism is also called a long boat 121, and the longitudinal movement mechanism 122 is also called a short boat. The long boat 121 and the short boat are also collectively referred to as a road base plate, such as four road base plates. The long boat 121 under the construction platform 11 at one end of the inclined static pressure pile device 2 can be called a first long boat 1211, and the long boat 121 under the construction platform 11 at the other end can be called a second long boat 1212. The first long boat 1211 and the second long boat 1212 are both provided with devices for linearly moving the construction platform, such as the first long boat 1211 having a first transverse slide rail 12111 and a first hydraulic cylinder 12112 such as an oil cylinder driving the construction platform 11 to move laterally and linearly along the first transverse slide rail 12111, and the second long boat 1212 having a second transverse slide rail 12121 and a second hydraulic cylinder 12122 such as an oil cylinder driving the construction platform 11 to move laterally and linearly along the second transverse slide rail 12121. It is not difficult to understand that the first hydraulic cylinder 12112 and the second hydraulic cylinder 12122 act synchronously to drive the construction platform 11 to move forward or backward laterally. The inclined static pressure pile device 2 is arranged on the construction platform 11 above the first long boat 1211 in an inclined state with a high outer end and a low inner end. The above is the prior art.

[0032] The invention points of the utility model inclined static pressure pile pressing equipment are as follows.

[0033] An inclined drilling device 3 is provided on an outer side construction platform 11 of an inclined static pressure pile device 2 of the utility model, and the axis of the drill rod 31 of the inclined drilling device 3 is parallel to the axis of the pile holding hole 231 of the pile holding box 23 of the inclined static pressure pile device 2, and the axis of the drill rod of the inclined drilling device 3, i.e. the inclined line, and the axis of the pile holding hole of the inclined static pressure pile device, i.e. the inclined line, are on the same inclined plane. The utility model inclined static pressure pile device can also be called a composite inclined pile driver.

[0034] It is not difficult to understand that the axis of the drill rod 31 of the inclined drilling device 3 is parallel to the axis of the pile holding hole 231 of the pile holding box 23 of the inclined static pressure pile device 2, that is, the angle between the axis of the drill rod of the inclined drilling device 3 and the horizontal line is equal to the angle between the axis of the pile holding hole 231 of the pile holding box 23 of the inclined static pressure pile device 2 and the horizontal line. Figure 3 The extended line 311 of the axis of the drill rod is shown. It is easy to understand that the extended line 311 of the axis of the drill rod includes the axis of the drill rod or includes the axis section of the drill rod. Figure 4 The extended line 2311 of the axis of the pile holding hole of the pile holding box 23 is shown. It is easy to understand that the extended line 2311 of the axis of the pile holding hole includes the axis of the pile holding hole 23 or includes the axis segment of the pile holding hole 23. Figure 4 In the embodiment, the extension line 2311 of the axis of the pile holding hole is also the axis of the two symmetrically arranged pile pressing hydraulic cylinders 22 such as the oil cylinder. Figure 3 In the figure, the extension line 311 of the axis of the drill rod and the extension line 2311 of the axis of the pile hole are the same oblique line, that is, the axis of the drill rod 31, the axis of the power head 36 and the axis of the center hole 41 of the prefabricated hollow square pile shown in the figure are all the same oblique line. It is not difficult to understand that, except for the lines extending at both ends of the oblique line which are solid lines, the rest of the line segments can be understood as dotted lines. Figure 4 In FIG. 2 , the extension line 2311 of the axis of the pile hole and the extension line 311 of the axis of the drill rod are also the same oblique line. It is also not difficult to understand that, except for the lines extending at both ends of the oblique line which are solid lines, the rest of the line segments can be understood as dotted lines. Figure 7 In the embodiment, the extended line 2311 of the axis of the pile hole and the axis of the central hole 41 of the prefabricated hollow square pile are the same oblique line, and the extended line 3111 of the axis of the drill rod, i.e. the inclined line, and the extended line 2311 of the axis of the pile hole, i.e. the inclined line, are on the same inclined plane. Figure 7 In the figure, the extension line 311 of the axis of the drill rod can be understood as a dotted line, and the extension line 2311 of the axis of the pile hole is only a solid line segment. The axis is also called the center line or the center axis.

[0035] The inclined drilling device 3 includes an inclined support frame 32 installed on the construction platform 11. The inclined support frame 32 is provided with a lifting hydraulic cylinder 33 such as an oil cylinder for driving a power head 36 to move linearly along the inclined support frame 32. The free end of the piston rod 331 of the lifting hydraulic cylinder 33 is hinged on the fixed plate 321 at the top of the inclined support frame 32, and one end of the cylinder barrel 332 of the lifting hydraulic cylinder 33 is fixed to the power head 36 such as by welding or screw connection.

[0036] It is not difficult to understand that the driving device on the diagonal support frame for driving the power head to move linearly along the diagonal support frame can also be a driving device other than the lifting hydraulic cylinder, such as a winch in the prior art can be used to drive the power head to move linearly along the diagonal support frame via a wire rope for lifting. The driving chain in the prior art can also be used to drive the power head to move linearly along the diagonal support frame for lifting.

[0037] The diagonal support frame 32 has a guide structure 34 that makes the axis of the drill rod 31 always parallel to the axis of the diagonal support frame 32, so as to ensure that the axis of the drill rod 31 is always parallel to the axis of the pile holding hole of the pile holding box 23 of the inclined static pile device 2, and the axis of the drill rod 31, i.e. the inclined line, and the axis of the pile holding hole 231 of the pile holding box 23 of the inclined static pile device 2, i.e. the inclined line, are always on the same inclined plane. Figure 3 , Figure 5 and Figure 6 As shown, the specific structure of the guide structure 34 may be that a guide plate 341 is fixed at the bottom end of the diagonal support frame 32, and a pair of center holes are provided on the guide plate 341 for guiding the drill rod 31, and the axis of the center hole is in the same straight line as the axis of the power head 36 and the axis of the drill rod 31.

[0038] The diagonal support frame 32 can be fixed to a fixed counterweight 131 on the construction platform 11 via a support plate, such as a flange 351 with a sleeve on the vertical plate of an L-shaped support plate 35, and the flange 351 with a sleeve is screwed and fixed to a flange on the vertical surface of the fixed counterweight 131 via screws and nuts. The inclined bottom surface 322 of the diagonal support frame 32 is fixed against an inclined surface 1311 of the fixed counterweight 131 on the construction platform 11, such as by welding.

[0039] It is not difficult to understand that the above is only a specific fixed structure. In the actual manufacturing process, the fixed structure can have many specific structures, and any method of fixing is fine, as long as the axis of the drill rod 31 of the inclined drilling device 3 mentioned above is parallel to the axis of the pile holding hole 231 of the pile holding box 23 of the inclined static pressure pile device 2, and the axis of the drill rod of the inclined drilling device 3, that is, the inclined line, and the axis of the pile holding hole of the inclined static pressure pile device, that is, the inclined line, are on the same inclined plane.

[0040] The above is a structure in which the diagonal support frame 32 is fixedly connected to the construction platform 11, such as a fixed counterweight block 131 fixed on the construction platform 11, that is, a structure in which the angle remains unchanged.

[0041] During the actual construction process, if the frequency of change of the inclination angle of the inclined pile driving device is relatively high, in order to adapt to the change, the diagonal support frame can also be a structure with a changeable angle relative to the construction platform. For example, the inner side of the diagonal support frame can be hinged to a counterweight block on the construction platform via a support plate, and a hydraulic cylinder such as an oil cylinder can be provided on the outer side of the diagonal support frame to support the diagonal support frame and adjust the relative angle. One end of the oil cylinder body can be hinged to the construction platform or a fixed counterweight block fixed on the construction platform, and the free end of the piston rod of the oil cylinder can be hinged to the diagonal support frame. In this way, the angle of the axis of the drill rod relative to the horizontal line can be adjusted to adapt to the change of the inclination angle of the inclined pile driving device.

[0042] The drill rod 31 has a detachable connection structure 312 in which two adjacent sections are butted against each other to extend the total length of the drill rod 31. The specific structure of the detachable connection 312 is the prior art, such as inserting a polygonal column into a polygonal hole of a coaxial line and fixing it with a transverse pin, or butting and fixing it with a flange and a plurality of bolts and nuts.

[0043] A liquid delivery pipe connecting a liquid source and a pump with a nozzle on the drill bit 37 is installed in the drill rod 31 and the drill bit 37. The liquid delivery pipe may be a cement slurry delivery pipe connecting a cement slurry source and a pump with a nozzle on the drill bit 37, or the liquid delivery pipe may be a water delivery pipe connecting a water source and a pump with a nozzle on the drill bit 37. The drill bit 37 may be a hole enlarging drill bit of the prior art.

[0044] The utility model inclined static pressure pile equipment may also include two anti-thrust anchor plates 5 arranged on the construction platforms 11 on both sides of the inclined static pressure pile device 2, and a linear drive structure that drives each anti-thrust anchor plate 5 to be obliquely inserted into the soil to provide anti-thrust for pile driving or drives the anti-thrust anchor plate 5 to separate from the soil to facilitate the movement of the equipment. The utility model inclined static pressure pile equipment, the counterweights 13 on both sides of the other end of the construction platform 11 can be movable counterweight blocks 132 that can rotate around their own axes, such as driven by a motor worm screw to rotate along the axis of its own axis to a predetermined position and self-lock. Figure 1 and Figure 2 As shown, the movable counterweight block 132 can be moved close to the inclined static pile driving device 2 during pile driving to increase the pile driving counterweight, thereby increasing the pile driving force. The movable counterweight block 132 can also be moved away from the inclined static pile driving device 2 during equipment movement, such as being rotated to the end at the other end of the construction platform 11, while keeping the center of gravity of the entire equipment balanced so that the equipment can move smoothly. For details of this paragraph, please refer to the prior utility model patent application of the applicant with application number 202420110410.0 and the name of the inclined pile driving device.

[0045] The utility model inclined static pressure pile equipment can be used for cement soil mixing pile or high pressure jet grouting pile construction, and can also be used for direct static pressure pile construction on soft soil foundation. The construction process is roughly as follows:

[0046] During the construction of cement soil mixing piles or high-pressure rotary jet piles, if the soil close to the ground is a soft silt layer, etc., the movable counterweight block 132 at the other end can be first rotated to a position close to the inclined static pressure pile device 2, and then the inclined reverse thrust anchor plate 5 with its inclination direction opposite to that of the inclined static pressure device is inserted into the soil, and then the inclined static pressure pile device 2 is used to press a section of pipe piles such as a prefabricated hollow square pile 4 into the soil. At this time, since the soil is a silt layer, it can be pressed down to the highest point of the prefabricated hollow square pile 4 slightly above the floor surface 6. Then, the two inclined reverse thrust anchor plates 5 are pulled out, and the first hydraulic cylinder 12112 on the first long ship 1211 and the second hydraulic cylinder 12122 on the second long ship 1212 are used to synchronously move the construction platform 11 horizontally, so that the drill bit 37 and the drill rod 31 of the inclined drilling device 3 are located above the central hole 41 of the prefabricated hollow square pile 4, and the axes of the drill bit 37 and the drill rod 31 are in the same straight line with the axis of the central hole 41 of the prefabricated hollow square pile 4. Then, the drilling and mixing grouting of the cement-soil mixing pile or the drilling and high-pressure rotary spraying of the high-pressure rotary spraying pile are carried out. At this time, the central hole 41 of the prefabricated hollow square pile plays a good guiding role for the drill rod 31, so that the axis of the drilled hole can basically always be kept in the same straight line. When the inclined drilling device 3 drills to the expected depth, the drill rod 31 and the drill bit 37 are withdrawn. The first hydraulic cylinder 12112 on the first long ship 1211 and the second hydraulic cylinder 12122 on the second long ship 1212 are then used to synchronously move the construction platform 11 laterally, so that the axis of the pile hole 231 of the pile holding box 23 of the inclined static pressure pile device 2 is on the same oblique straight line as the axis of the center hole 41 of the planted or pressed prefabricated hollow square pile, and then the inclined reverse thrust anchor plate 5 whose inclination direction is opposite to that of the inclined static pressure pile device is inserted into the soil, and then the inclined static pressure pile device 3 is used to connect the next section of the prefabricated hollow square pile 4 with the original section of the prefabricated hollow square pile 4 that has been pressed in, such as end plate welding, and then continue to press down the prefabricated hollow square pile 4, and then continue to press down the subsequent sections of the prefabricated hollow square pile 4, or accompany the cross drilling mentioned above.

[0047] During the construction of cement soil mixing piles or high pressure rotary jet piles, if the soil near the floor surface 6 is a relatively hard soil layer at the beginning, the drilling and mixing grouting of cement soil mixing piles or the drilling and high pressure rotary jet cement slurry of high pressure rotary jet piles can be carried out first, and then the construction platform 11 is moved horizontally according to the above construction steps to put the inclined static pressure pile device 2 in place and pile pressing or pile planting, or pile connection and pile pressing, or cross drilling can be carried out according to the above steps.

[0048] If used for direct static inclined pile construction on soft soil foundation, the inclined piles can be pressed according to the above softer silt layer pressed pile construction steps, such as pressing prefabricated hollow square piles. When encountering harder soil layers or local rock blocks, move the construction platform and drill holes according to the above-mentioned steps. Water flushing can be used during drilling, and grouting can also be accompanied. When drilling to the expected depth, repeat the above pile pressing or pile connection construction steps.

[0049] During the drilling process, if the drill rod 31 is not long enough, the drill rod can be extended section by section through the detachable connecting structure 312. For example, first drill a section of the drill rod 31 into the soil, then release the connection between it and the power head 36, and then lift the power head 36, and then connect a new section of the drill rod 31 to the next section of the drill rod 31 and the power head 36, that is, connect the new drill rod, and then continue drilling.

[0050] It is not difficult to understand that while the power head drives the drill rod to rotate to drill a hole, grouting or water jetting is carried out simultaneously.

[0051] For the sake of intuitiveness, prefabricated hollow square piles 4 are drawn at the inclined static pressure pile device 2 and below the inclined drilling device 3 in the figure. The two prefabricated hollow square piles 4 can be understood as the same prefabricated hollow square piles 4, but they are in different construction states.

[0052] The above unmarked parts, structures or quantities are not shown in the drawings, and some parts are not marked in the drawings. The drawings are only for reference only.
