Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation construction, in particular to an integrated cast-in-place pile machine for engineering. Background Art

[0002] During the pile foundation construction process, the construction methods can be divided into precast pile construction and cast-in-place pile construction according to the type of pile. Precast pile construction is to directly drive the prefabricated pile columns into the ground by hammering, vibration or static pressure. Cast-in-place pile construction is to drill pile holes on the ground by a pile driver, and then use a spray anchor machine to spray cement slurry onto the inner wall of the pile hole. The cement slurry has a reinforcing effect on the inner wall of the pile hole to avoid hole collapse. After that, a prefabricated steel cage is placed in the pile hole, and concrete is poured into the pile hole through a conduit to form a pile body.

[0003] When using the cast-in-place pile construction method, since the pile hole is deep, the drill bit on the pile driver needs to have an inner cavity to hold the soil generated during drilling, and the pile driver needs to repeatedly lift and lower the drill bit so that the drill bit carries the soil to the ground to achieve the purpose of cleaning the pile hole. When the drill bit is lifted to the ground, it is necessary for workers or machinery to control the drill bit to open and drain the soil inside the drill bit. Due to the above many repeated steps, the distance the drill bit can drill each time is limited, which seriously affects the progress of the project. Summary of the Invention

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] like Figures 1 to 5As shown, an integrated bored pile machine for engineering use of the present invention includes a main rod 100 and a drilling unit 200 installed at the end of the main rod 100. The main rod 100 is used to provide power for the drilling work of the drilling unit 200. The drilling unit 200 includes:

[0046] The outer cylinder 201 is sleeved on the outer side of the main rod 100 and fixed relative to the main rod 100;

[0047] The digging part is installed on the outer cylinder 201 and is used to dig the soil;

[0048] The conveying part is used to transport the excavated soil upward. The conveying part is a plurality of spiral bodies 202 distributed circumferentially around the axis of the main rod 100, and the spiral bodies 202 are used to connect the main rod 100 and the outer cylinder 201;

[0049] The intercepting part is used to allow the excavated soil to be transported upward in one direction. The intercepting part is a plurality of sealing bodies 203 distributed circumferentially around the axis of the main rod 100. The sealing bodies 203 are allowed to be opened in one direction.

[0050] The spraying unit is installed on the outer cylinder 201 and is used to spray the solidifying slurry onto the inner wall of the borehole.

[0051] In the present invention, the main rod 100 can move up and down and rotate, so that the main rod 100 can drive the drilling unit 200 to move synchronously, thereby providing power for the drilling unit 200 to drill into the ground. The movement power of the main rod 100 can be provided by hydraulic, motor and other equipment. The cross-sectional shape of the main rod 100 can be any shape such as polygonal, circular, etc., and the main rod 100 can be spliced ​​and combined, that is, when the drilling unit 200 drills into a certain depth underground, the main rod 100 is not long enough, it can be docked and combined with other main rods 100. Of course, in normal use, if the length of the main rod 100 meets the construction requirements, its No need to combine; the drilling unit 200 is used to drill into the ground and form a pile hole. The outer cylinder 201 on the drilling unit 200 is mainly used to support the excavation part, transportation part, interception part and spraying part thereon, and the outer wall of the outer cylinder 201 can contact the inner wall of the pile hole; the excavation part can crush and excavate the soil when the drilling unit 200 rotates and drills, so as to facilitate the drilling unit 200 to drill into the ground smoothly. The structure of the excavation part can be fixed teeth or rotating teeth that can rotate in at least one direction; the transportation part can transport the soil excavated by the excavation part upward through the space between the outer cylinder 201 and the main rod 100, so that In order to reduce the amount of soil around the excavation part and reduce the difficulty of excavation, specifically, a number of spirals 202 can be used to transport the soil. At the same time, the spirals 202 can also connect the main rod 100 and the outer cylinder 201. The number of spirals 202, the pitch and other parameters can be determined according to actual conditions; the interception part can be installed on the top of the outer cylinder 201. When the spiral 202 transports the soil upward, the soil can push the interception part to open, so that the soil can move to the top of the interception part. The setting of the interception part can prevent the soil above from reversely entering the outer cylinder 201 downward, thereby achieving soil aggregation and isolation. Specifically, the intercepting portion can adopt a structure of several sealing bodies 203, which are distributed in a ring around the main rod 100, with one end of the sealing body 203 in contact with the outer wall of the main rod 100, and the other end of the sealing body 203 being rotatably mounted on the outer cylinder 201, and a plurality of limiting protrusions 204 for limiting and supporting each sealing body 203 can be provided on the inner wall of the outer cylinder 201. When the sealing body 203 contacts the limiting protrusions 204, the several sealing bodies 203 form a disc shape and seal the top of the outer cylinder 201. An elastic structure can also be provided between the sealing body 203 and the outer cylinder 201 to provide a reset elastic force for the sealing body 203;

[0052] It should be noted that, since the drilling unit 200 continuously moves downward during drilling, the conveying part can continuously move the soil to the vacant area above the outer cylinder 201, so that the soil accumulated above the outer cylinder 201 will not cause a significant obstacle to the opening of the sealing body 203; since some of the sealing bodies 203 pass through the gaps between two adjacent sealing bodies 203 when they are opened, this part of the soil will interfere with the closing of the sealing bodies 203 when they are closed, and the downward pressure of the soil above the outer cylinder 201 on the sealing bodies 203 can squeeze out the soil between the two adjacent sealing bodies 203, thereby enabling the sealing bodies 203 to close normally. Even if the sealing bodies 203 cannot be completely closed, the sealing bodies 203 can still block and isolate the soil.

[0053] In actual use, the main rod 100 will drive the drilling unit 200 to move synchronously, and the excavation part on the drilling unit 200 will destroy the soil, so that the drilling unit 200 can drill into the ground normally. During drilling, the soil crushed by the excavation part is transported upward to the top of the outer cylinder 201 through the rotation and transportation movement of the plurality of spiral bodies 202, and the sealing body 203 is squeezed by the soil and opened. As the drilling unit 200 continues to drill, the soil above the drilling unit 200 gradually increases. When the drilling unit 200 moves a specified distance, the main rod 100 moves upward. At this time, the main rod 100 drives the drilling unit 200 to move upward synchronously, and the drilling unit 200 can use the plurality of sealing bodies 203 thereon to The soil above the drilling unit 200 is pushed upwards. At this time, the drilling unit 200 can serve as an isolation layer, and the isolation layer is used to push the excavated loose soil upwards to the ground to achieve the cleaning of the pile hole. This part of the soil is scattered around near the pile mouth on the ground. Then the main rod 100 continues to move downwards and performs drilling work through the drilling unit 200. This is repeated to achieve the pile hole processing work. During the drilling process, since the inner wall of the pile hole is also a soil layer, in order to avoid the hole collapse phenomenon, the grouting unit can be used to spray solidifying slurry onto the inner wall of the pile hole to improve the stability of the pile hole. The working time of the grouting unit can be at least one of the processes of the drilling unit 200 drilling in or moving upwards.

[0054] The curing slurry mentioned above can be concrete, mortar mixture or mixed slurry containing an accelerating agent;

[0055] By utilizing the drilling unit 200 as an isolation layer, when the drilling unit 200 rises, the soil above it can be directly pushed upward and brought out of the pile hole, so that a large amount of soil can be cleared out at one time, which can greatly increase the single drilling depth of the drilling unit 200 and shorten the pile hole processing cycle. At the same time, since the drilling unit 200 only needs to push the soil upward, the drilling unit 200 does not need to perform other operations such as opening and closing, so its operation is simpler; since the drilling unit 200 only needs to dig the soil on its lower side and push it to its upper side, and the drilling unit 200 only needs to act as an isolation layer when moving upward, the thickness of the drilling unit 200 is allowed to be smaller, which can reduce the overall weight and volume of the drilling unit 200.

[0056] Optimized in the above embodiment, the excavation part is composed of a plurality of plates 205 mounted on the end of the outer cylinder 201 and crushing bodies 206 rotatably mounted on each plate 205 , each crushing body 206 being densely covered with crushing teeth;

[0057] The plate 205 can be fixed to the outer cylinder 201 by welding or other means, and the plate 205 is mainly used to support the crushing body 206 thereon. The crushing body 206 and the crushing bodies thereon are mainly used to crush the soil. Since the crushing body 206 can rotate on the plate 205, the shape of the crushing body 206 can be set to be spherical, and the rotation setting of the crushing body 206 can achieve rolling crushing of the soil. Compared with the hard extrusion crushing method, rolling crushing is more likely to crush hard objects in the soil, thereby reducing the difficulty of excavation; the crushing teeth can have structures of any shape such as cones and convex teeth;

[0058] Since the crushed soil needs to be transported by the screw 202, the crushing bodies 206 can be used as follows: Figure 3 In the installation mode, a plurality of crushing bodies 206 are distributed at the circumferential position of the end face of the outer cylinder 201. When the drilling unit 200 is excavating the soil, the plurality of crushing bodies 206 can first destroy the soil from the outer position of the excavation area, and the excavation range can be first circled, so that the soil inside can be loosened, the connectivity between the inner soil and the outer soil can be destroyed, and the excavation of the inner soil can be facilitated. After that, the inner soil can be directly shoveled and excavated by the end of the spiral body 202.

[0059] During excavation, if the diameter of the pile hole is consistent with the diameter of the outer cylinder 201, that is, the outer wall of the outer cylinder 201 contacts the inner wall of the pile hole, the friction between them will affect the drilling work of the drilling unit 200, and a greater force needs to be provided to the drilling unit 200, which will increase the energy loss. To avoid this phenomenon, the following method can be used: Figure 3In the manner shown, each plate 205 is inclined toward the axis of the main rod 100, and the range of movement of each crushing body 206 extends beyond the rotation area of ​​the outer cylinder 201. As can be seen from the above, the area of ​​the working area of ​​the crushing body 206 is larger than the area of ​​the outer cylinder 201. In this way, the diameter of the pile hole formed by the crushing body 206 when digging the soil will be slightly larger than the diameter of the outer cylinder 201, that is, a small gap will exist between the inner wall of the pile hole and the outer wall of the outer cylinder 201, thereby preventing the outer cylinder 201 from contacting the inner wall of the pile hole.

[0060] In order to further reduce the difficulty of digging the soil at the end of the spiral body 202, the following method can be used: Figure 3 In the manner shown, the end of the spiral body 202 facing the crushing body 206 is provided with a sawtooth 207; the sawtooth 207 at the end of the spiral body 202 can facilitate the rapid shoveling and excavation of the inner soil after being circled by several crushing bodies 206, thereby facilitating the crushing of the soil.

[0061] Optimizing the above implementation, a shovel 209 is provided on the outer cylinder 201 between two adjacent crushing bodies 206, and a plurality of spiral ridges 208 are provided on the outer wall of the outer cylinder 201, and the spiral ridges 208 are connected to the shovel 209;

[0062] In the present invention, the spiral ridge 208 is arranged between the inner wall of the pile hole and the outer wall of the outer cylinder 201. When the outer cylinder 201 rotates, the spiral ridge 208 can push the loose soil between the outer cylinder 201 and the inner wall of the pile hole upward, thereby preventing the soil from gathering and solidifying between the outer cylinder 201 and the inner wall of the pile hole, and reducing the drilling difficulty of the drilling unit 200; since the working area of ​​the crushing body 206 is larger than the coverage range of the outer cylinder 201, part of the soil crushed by the crushing body 206 will be located outside the outer cylinder 201. The shovel 209 can be used to shovel this part of the soil and push it upward to the position of the spiral ridge 208, thereby facilitating the timely cleaning of this part of the soil.

[0063] Optimized on the above implementation, such as Figure 5As shown, the spraying part includes a plurality of feeding pipes 210 located on the inner side of the outer cylinder 201 and a plurality of material troughs 211 installed on the inner wall of the outer cylinder 201. The feeding pipes 210 are connected to the corresponding material troughs 211. A plurality of discharge holes 212 are opened on the side wall of the material trough 211, and each discharge hole 212 extends to the outer wall of the outer cylinder 201. The solidified slurry can be introduced into the material trough 211 through the feeding pipes 210, and the solidified slurry in the material trough 211 is then sprayed outwards to the pile through the plurality of discharge holes 212. On the inner wall of the hole; since the material holding trough 211 and the plurality of discharge holes 212 are all located on the outer cylinder 201, the timing for spraying the solidified slurry is when the drilling unit 200 is digging or when the drilling unit 200 is moving upward, and the shielding effect of the drilling unit 200 on the soil above or below it can facilitate the attachment of as much slurry as possible to the inner wall of the pile hole; since the outer cylinder 201 is always in a rotating state, in order to prevent soil from entering the discharge holes 212, the discharge holes 212 can be set at an angle.

[0064] Optimized on the above implementation, such as Figure 4 and Figure 6 As shown, the main rod 100 is hollow, and a plurality of docking holes 213 are opened on the outer wall of the main rod 100, and the docking holes 213 are connected to the corresponding feed pipes 210;

[0065] The end of the main rod 100 corresponding to the outer cylinder 201 is open, and a sealing cone 214 is encapsulated at the opening position. The sealing cone 214 is allowed to move along the axis of the main rod 100;

[0066] The main rod 100 is provided with a guide unit 300 for controlling the solidified slurry in the main rod 100 to flow out through the docking hole 213 or the end opening of the main rod 100;

[0067] In the present invention, the hollow setting of the main rod 100 is mainly used to transport the solidifying slurry. The docking hole 213 on the main rod 100 can be connected to the feeding pipe 210. The opening at the bottom of the main rod 100 can be used to allow the solidifying slurry to flow downward to the bottom of the pile hole through the opening after the pile hole is excavated, thereby forming a protective layer at the bottom of the hole and achieving pre-hardening treatment of the hole bottom; when the drilling unit 200 is drilling forward, due to the reverse thrust of the soil, the sealing cone 214 keeps sealing the bottom opening of the main rod 100, preventing soil from entering the main rod 100, and When the drilling unit 200 moves upward, the sealing cone 214 is separated from the soil, and at this time the sealing cone 214 can be separated from the main rod 100; in some embodiments, an elastic structure can also be set between the sealing cone 214 and the main rod 100, so that the sealing cone 214 maintains a sealed state for the bottom opening of the main rod 100, and only when the pressure in the main rod 100 is large, the sealing cone 214 is pushed to open by the pressure; the diversion unit 300 is mainly used to control the flow direction of the solidifying slurry, and at the same time point, the solidifying slurry can only flow out from the docking hole 213 or one of the bottom openings of the main rod 100.

[0068] Optimized on the above implementation, such as Figures 6 and 7 As shown, the guide unit 300 includes an isolation bucket 301 and an isolation cylinder 302 installed in the main rod 100. A movable sleeve 303 is slidably inserted into the isolation cylinder 302. One end of the movable sleeve 303 is slidably sleeved on the isolation bucket 301, and the other end of the movable sleeve 303 is provided with a plurality of side openings 305.

[0069] A separating ring 304 is provided between the isolating bucket 301 and the isolating cylinder 302, and the separating ring 304 is fixed relative to the movable sleeve 303. A first gas transmission channel 307 and a second gas transmission channel 308 are provided in the main rod 100. The space between the separating ring 304 and the isolating cylinder 302 is connected to the first gas transmission channel 307, and the space between the separating ring 304 and the isolating bucket 301 is connected to the second gas transmission channel 308.

[0070] The side port 305 is connected to the space on either side of the isolation cylinder 302;

[0071] In the present invention, the isolation bucket 301 and the isolation cylinder 302 are both fixed on the inner wall of the main rod 100, the separation ring 304 can be movably arranged between the isolation bucket 301 and the isolation cylinder 302, and the space between the isolation bucket 301 and the separation ring 304 can be set as a first chamber 309, the first chamber 309 is connected to the second gas transmission channel 308, the space between the isolation cylinder 302 and the separation ring 304 can be set as a second chamber 310, the second chamber 310 is connected to the first gas transmission channel 307, the movable sleeve 303 slides and is inserted into the isolation cylinder 302, and the movable sleeve 303 is movably arranged between the isolation bucket 301 and the isolation cylinder 302. The top of the sleeve 303 is slidably connected to the first chamber 309; in the natural state, the side port 305 is located below the isolation cylinder 302, the separation ring 304 blocks the docking hole 213, and a retaining ring can be provided on the outer wall of the movable sleeve 303. The retaining ring and the isolation cylinder 302 abut against each other to limit the movable sleeve 303. The solidified slurry in the main rod 100 can be introduced into the movable sleeve 303 through the isolation bucket 301, and the solidified slurry in the movable sleeve 303 is introduced into the lower space of the isolation cylinder 302 through a number of side ports 305. The solidified slurry can push The sealing cone 214 is opened and discharged through the bottom opening of the main rod 100; when the first air supply channel 307 inflates the second chamber 310, the air pressure inside the second chamber 310 increases and pushes the separation ring 304 to move upward, and the separation ring 304 carries the movable sleeve 303 to move upward synchronously, and the side port 305 moves upward into the second chamber 310. At this time, the separation ring 304 is separated from the docking hole 213, and the air in the first chamber 309 can be discharged through the second air supply channel 308. The second chamber 310 is connected to the feed pipe 210 through the docking hole 213, and the movable sleeve 303 is moved upward. The solidified slurry in the pile is introduced into the second chamber 310 through the side port 305, and the solidified slurry in the second chamber 310 is introduced into the material trough 211 through the docking hole 213 and the feed pipe 210, thereby realizing the transportation control of the solidified slurry; by adopting the inflation method, the high-pressure gas can be mixed with the solidified slurry and sprayed out through the discharge hole 212, thereby increasing the injection speed of the solidified slurry, making it easier for the solidified slurry to penetrate deeper into the soil layer on the inner wall of the pile hole, and this method can reduce the blocking effect of the small amount of soil between the outer cylinder 201 and the inner wall of the pile hole on the solidified slurry.

[0072] Optimized on the above implementation, such as Figure 7 As shown, the isolation bucket 301 and the separation ring 304 are connected by a number of elastomers 306; in order to realize the reset work of the movable sleeve 303 in the natural state, the elastomer 306 can be used to provide elastic force to the separation ring 304 so that the retaining ring on the movable sleeve 303 contacts the isolation cylinder 302. At this time, the side port 305 remains connected to the lower space of the isolation cylinder 302.
