Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a water drilling pile construction device for a waterway and a use method thereof. BACKGROUND

[0002] When the water drilling pile is constructed, the enclosure needs to be buried in advance, so as to fix the pile center through the enclosure, facilitate accurate positioning when drilling and rotary digging, and prevent hole wall collapse and sand flow phenomenon when drilling and rotary digging, thereby ensuring the stability of drilling.

[0003] When the enclosure is inserted into the underwater soil, the enclosure plates are sequentially inserted into the soil along the ring, so that the enclosure plates form a ring-shaped blocking effect underwater. However, the sequential insertion of the enclosure plates separately can cause the problem of incomplete sealing between the enclosure plates. When the entire enclosure is vertically inserted into the underwater soil, the underwater blocking object (stone) can easily block the edge of the enclosure. Since the enclosure is vertically inserted, the stone is not easily extruded from the blocking position by the insertion force, so that the blocking object (stone) needs to be cleaned again to continue the insertion, causing the insertion construction of the enclosure to be difficult.

DETAILED DESCRIPTION

[0030] As Figures 1 to 7As shown in the present application, a water drilling bored pile construction device for waterway is provided, which comprises a small arm 1, a surrounding mechanism 2, a large arm 3, a rotator 4, a floating plate 5 and a driving main body 6. The driving main body 6 runs on the surface of the floating plate 5, and drives the large arm 3 and the small arm 1 to rotate and cooperate. The rotator 4 rotates at the outer end of the small arm 1, and the surrounding mechanism 2 is fixed inside the rotator 4. The driving main body 6 drives the rotator 4 to rotate through electrical signals, and makes the surrounding mechanism 2 rotate downward into the water.

[0031] The surrounding mechanism 2 is provided with a stress structure 21, an extension structure 22, a guide mechanism 23, a push rod 24, a fixed block 25, a hydraulic device 26, a surrounding pipe 27 and a support rod 28. The extension structure 22 is annularly distributed at the lower end of the fixed block 25, and slides on the lower surface of the fixed block 25. The hydraulic device 26 is fixed in the middle of the fixed block 25, and the push rod 24 is located at the output end of the hydraulic device 26. The fixed block 25 drives the extension structure 22 to rotate under the rotation of the rotator 4, and drives the hydraulic device 26 to push the push rod 24 out, so that the stress structure 21 at the lower end of the extension structure 22 fixes the surrounding pipe 27. The support rod 28 is annularly distributed inside the surrounding pipe 27. The guide mechanism 23 is fixed at the lower end of the surrounding pipe 27. The surrounding pipe 27 drives the guide mechanism 23 to rotate and insert into the underwater soil. When the lower end of the guide mechanism 23 touches the barrier, the guide mechanism 23 inclines inward to guide the barrier.

[0032] The stress structure 21 is provided with a transmission structure 211, a stress block 212, a concave structure 213, a support plate 214, an inclined rod 215 and an elastic plate 216. The transmission structure 211 is hinged on the side surface of the push rod 24. The inner side of the concave structure 213 corresponds to the mutual adhesion of the elastic plate 216. The inclined rod 215 is connected to the elastic plate 216 and the push rod 24 through hinges at both ends. When the push rod 24 is pushed, it drives the inclined rod 215 to press the elastic plate 216, and makes the elastic plate 216 bend outward. The stress block 212 fixed inside the elastic plate 216 presses against the inner side of the surrounding pipe 27, and the transmission structure 211 inclines inside the support plate 214. The inclined activity force makes the transmission structure 211 drive the concave structure 213 to press against the outer side of the surrounding pipe 27.

[0033] In addition, the stress block 212 is made of rubber. When the stress block 212 presses against the inner side of the surrounding pipe 27, it can generate a larger friction force. The position where the stress block 212 presses against the inner side of the surrounding pipe 27 and the position where the transmission structure 211 presses against the outer side of the surrounding pipe 27 are in an inclined state, thereby making the positions where the two sides of the surrounding pipe 27 are fixed and pressed present a certain lever effect. When the surrounding pipe 27 is in a tubular structure, the two fixed and pressed points have a balanced pressing force effect, and generate a relatively stable fixed and pressed effect on the surrounding pipe 27.

[0034] The transmission structure 211 is provided with a top plate 11, a pressing plate 12, a first rotating shaft 13 and a second rotating shaft 14. The second rotating shaft 14 at the lower end of the top plate 11 rotates in the pressing plate 12. The first rotating shaft 13 is fixed on both sides of the pressing plate 12. The pressing plate 12 rotates in the inner side of the supporting plate 214 through the first rotating shaft 13. When the second rotating shaft 14 drives the top plate 11 to tilt, the top plate 11 presses the pressing plate 12 through the second rotating shaft 14. The pressing plate 12 rotates clockwise in the supporting plate 214 through the first rotating shaft 13. The first rotating shaft 13 is pressed against the outer side of the surrounding pipe 27 through the concave structure 213.

[0035] The telescopic structure 22 is provided with a sliding bar 221 and a sliding seat 222. The sliding bar 221 is fixed on the upper end of the sliding seat 222. When the sliding bar 221 tilts, the sliding seat 222 slides outward on the lower surface of the fixed block 25 through the sliding bar 221. The telescopic structure 22 expands outward.

[0036] The hydraulic device 26 drives the push rod 24 to push out. The push rod 24 drives the tilting rod 215 and the transmission structure 211 to move. The tilting rod 215 and the transmission structure 211 push the sliding bar 221 at the upper end of the sliding seat 222 to slide on the track of the lower surface of the fixed block 25. When the concave structure 213 corresponds to the upper side of the surrounding pipe 27, the fixed block 25 is pushed downward. The surrounding pipe 27 enters the concave structure 213. When the tilting rod 215 and the transmission structure 211 are continuously driven by the push rod 24, the tilting rod 215 will press the elastic plate 216. The elastic plate 216 is elastically bent. The stress block 212 inside the elastic plate 216 is pressed against the inner side of the surrounding pipe 27. At the same time, the transmission structure 211 rotates inside the supporting plate 214. The lower end of the transmission structure 211 is pressed against the outer side of the surrounding pipe 27 through the concave structure 213. The effect of clamping and fixing the surrounding pipe 27 from the inside and outside is formed. Different sizes of the surrounding pipe 27 can be fixed and clamped. The problem that the surrounding pipe 27 is not easy to fix when the size is different is avoided.

[0037] The concave structure 213 is provided with a friction ring 31, a clamping block 32 and a metal ring 33. The friction ring 31 is provided with two, which are fixed on both sides of the metal ring 33. One of the friction rings 31 corresponds to the elastic plate 216. The clamping block 32 is arranged in an annular array at the lower end of the metal ring 33. The upper end of the surrounding pipe 27 is provided with a matching resistance block 101 with the clamping block 32. After the metal ring 33 moves downward, the clamping block 32 is engaged with the resistance block 101 at the upper end of the surrounding pipe 27. The upper end of the metal ring 33 is a protruding structure. The metal ring 33 is clamped at the lower end of the telescopic structure 22 through the protruding structure. When the telescopic structure 22 rotates, the clamping block 32 at the lower end of the metal ring 33 drives the surrounding pipe 27 to rotate.

[0038] And, when the enclosure tube 27 enters the concave structure 213, the protruding structure on the upper end of the metal ring 33 is engaged with the lower end of the sliding seat 222, so that the blocking block 101 on the upper end of the enclosure tube 27 is engaged with the clamping block 32, and when the sliding seat 222 rotates, the protruding structure can better drive the clamping block 32 on the lower end of the metal ring 33 to rotate the blocking block 101 on the upper end of the enclosure tube 27.

[0039] In the present application, when the driving hydraulic device 26 drives the push rod 24 to push the translation, the upper end of the top plate 11 rotates outside the push rod 24, so that the top plate 11 tilts and rotates to a horizontal state, thereby the top plate 11 drives the second rotating shaft 14 to move outward while generating a certain pushing force, so that the second rotating shaft 14 generates a clockwise rotating force on the upper end of the pressing plate 12. When the enclosure tube 27 is not in the position of the concave structure 213, the rotating force of the pressing plate 12 drives the sliding seat 222 to move outward, and when the enclosure tube 27 is blocked in the position of the concave structure 213, the sliding seat 222 is in a fixed state, and the pressing plate 12 can only rotate clockwise inside the support plate 214 through the first rotating shaft 13, thereby driving the lower end of the pressing plate 12 to press the friction ring 31, and making the friction ring 31 abut against the outside of the enclosure tube 27, and then the outside of the enclosure tube 27 generates an inward force, and the abutment of the force block 212 generates a lever effect, so that the enclosure tube 27 can be better fixed when being lifted, and then the rotation of the rotator 4 drives the fixed block 25 to rotate and downward force, thereby driving the enclosure tube 27 to rotate downward and insert into the underwater soil, avoiding the problem of incomplete sealing caused by separate insertion of the enclosure tube 27, and preventing the problem of poor waterproof effect caused by the gap between the enclosure tube 27 and the underwater soil.

[0040] And, when the enclosure tube 27 is clamped to the concave structure 213, the blocking block 101 on the upper end of the enclosure tube 27 is engaged with the clamping block 32, so that the fixed block 25 rotates synchronously through the engagement of the clamping block 32 and the blocking block 101, avoiding the problem that the enclosure tube 27 is too smooth to rotate and drive, and the friction ring 31 is made of rubber material and has the characteristics of large friction, so that the fixation of the enclosure tube 27 is more reliable when the lower end of the pressing plate 12 drives the friction ring 31 to abut against the enclosure tube 27, avoiding the problem that the enclosure tube 27 is too smooth and easy to slip when being fixed.

[0041] The guiding mechanism 23 is provided with a guide plate 41, a rotating plate 42, a spring 43 and a fixed strip 44, the fixed strip 44 is fixed to the lower end of the enclosure tube 27, the rotating plate 42 is hingedly connected to the two sides of the fixed strip 44, and the guide plate 41 rotates in the rotating plate 42, the inner side of the guide plate 41 is provided with two springs 43, and the upper end of the spring 43 is fixed to the lower end of the support rod 28, when the lower end of the guide plate 41 touches the blocking object, the guide plate 41 tilts and rotates around the center of the rotating plate 42 under the elasticity of the spring 43, and when the rotating plate 42 rotates on the two sides of the fixed strip 44, it drives the guide plate 41 to tilt towards the center axis of the enclosure tube 27.

[0042] And, the spring 43 is in a static state, the guide plate 41 is inclined by 10°, and the guide plate 41 can only rotate by 20° inside the rotating plate 42, and the rotating plate 42 can only rotate by 10° on both sides of the fixed strip 44, when the guide plate 41 is rotated and inserted into the underwater soil, since the lower end of the guide plate 41 is closer to the central axis than the retaining tube 27, the lower end of the guide plate 41 is rotated and inserted into the soil, and the guide plate 41 guides the soil outward, so that the soil is not easy to approach the inner wall of the retaining tube 27, and the amount of soil can be reduced when the soil in the retaining tube 27 is rotated and excavated.

[0043] In the application, when the guide plate 41 touches the barrier, the guide plate 41 is inclined and rotated towards the central axis of the retaining tube 27, and the lower end of the guide plate 41 slides on the barrier, at this time, the spring 43 generates an elastic force on the barrier to make the barrier elastically move outwardly relative to the inclined guide plate 41, so as to avoid the barrier entering the inside of the retaining tube 27, and prevent the barrier from blocking the rotation and insertion of the guide plate 41 into the soil, and when the barrier is rough, the inclined force of the guide plate 41 is not easy to slide on the barrier, at this time, the rotating plate 42 drives the guide plate 41 to increase the inclination angle again, so as to improve the sliding force of the guide plate 41, and make the lower end of the guide plate 41 slide inwardly on the surface of the barrier under the downward rotating force, and guide the barrier outwardly by the guide plate 41, so as to avoid the problem that the barrier causes the insertion to be difficult when the retaining tube 27 is rotated and inserted.

[0044] After the guide plate 41 guides the barrier and the soil outwardly, the soil at the position outside the guide plate 41 enters the outside of the retaining tube 27, at this time, since the soil outside the guide plate 41 is extruded outwardly after the retaining tube 27 is inserted, the soil extrudes the retaining tube 27, enhances the fitting pressure of the soil on the outside of the retaining tube 27, and improves the stability of the retaining tube 27 after being inserted into the underwater soil.

[0045] The use method of the water drilling bored pile construction device for a channel, according to the water drilling bored pile construction device for a channel, the specific use method is as follows:

[0046] S1: the floating plate 5 floats on the water, and the staff controls the driving of the large arm 3 and the small arm 1 to rotate in the driving body 6, so that the rotator 4 can be vertically inserted into the underwater, and the driving of the rotator 4 is controlled by the driving body 6 to rotate the retaining mechanism 2, so that the retaining mechanism 2 is rotated and inserted into the underwater;

[0047] S2: the fixed block 25 is fixed by the rotator 4 and drives the fixed block 25 to rotate, and when the push rod 24 at the output end of the hydraulic device 26 moves, the retaining tube 27 is clamped in the stress structure 21 at the lower end of the telescopic structure 22, so that the rotation of the fixed block 25 drives the retaining tube 27 to rotate;

[0048] S3: the push rod 24 drives the oblique rod 215 and one end of the transmission structure 211, so that the oblique rod 215 drives the force block 212 inside the elastic plate 216 to press against the inside of the enclosure pipe 27, and at the same time the lower end of the transmission structure 211 drives the concave structure 213 to press against the outside of the enclosure pipe 27, forming the pressing against the enclosure pipe 27;

[0049] S4: when the enclosure pipe 27 rotates downward to insert, the guide plate 41 in the guide mechanism 23 first touches the blocking object, so that the guide plate 41 rotates through the rotating plate 42, and makes the rotating plate 42 rotate on both sides of the fixed strip 44, so that the guide plate 41 inclines to guide the blocking object to move outward under the elastic resistance of the spring 43, and makes the blocking object guide outward.

[0050] The above is only a preferred embodiment of the present application, and therefore cannot limit the scope of the present application, that is, equivalent changes and modifications made according to the scope of the present patent and the content of the specification should still be within the scope of the present application.
