[0021] and

[0022]

[0023] wherein, v 1 represents the rotational speed of the variable-frequency motor, e(t) represents the deviation between the target burial depth and the actual value, and K p , K i and K d are correction parameters;

[0047] The following describes the implementation manners of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0048] Please refer to Figures 1 to 7 . It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those who are familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have technical essence. Any modification of the structure, change of the ratio relationship, or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention.

[0049] Please refer to Figures 1 to 6 , the present invention discloses a pouring pile perfusion device for construction, which includes a conduit 100, a concrete pumping unit 200, a pile frame support unit 300, and an intelligent control unit 400. The conduit 100 is connected to the concrete pumping unit 200 to pump concrete into the pouring hole through the conduit 100 by the concrete pumping unit 200. It can be understood that the conduit 100 is connected to the pile frame support unit 300 to provide support and a certain degree of angle adjustment for the conduit 100 through the pile frame support unit 300. At the same time, the intelligent control unit 400 can be used to obtain relevant data generated during the pumping of concrete, as well as to control the concrete pumping unit 200 and adjust the height of the conduit 100.

[0050] Specifically, the conduit 100 is composed of multiple high-strength alloy steel pipes 110 connected by quick-release joints, and the inner wall of the steel pipe is coated with a friction-reducing coating 111. By providing the friction-reducing coating 111 on the inner wall of the conduit 100, the friction between the concrete and the inner wall of the conduit 100 can be effectively reduced, the actual pouring effect can be improved, and it is also convenient to detect the flow rate of the concrete in the conduit 100.

[0051] In some embodiments, the drag reduction coating 111 is a polyurethane-nano ceramic composite material. However, this is not limited thereto, and it can be determined according to actual requirements. A tapered anti-blocking flaring 120 is provided at the end of the conduit 100, which can effectively prevent the concrete from being blocked at the end of the conduit 100. Among them, the inner diameter of the anti-blocking flaring 120 gradually increases from the inside to the outside, and a spiral diversion groove 121 is provided on the flaring surface. By setting the spiral diversion groove 121, the concrete can be guided to flow along a spiral trajectory, reducing the radial movement of the fluid and avoiding the separation of the aggregate and the slurry due to the difference in centrifugal force. At the same time, the spiral structure decomposes the axial impact force of the concrete into tangential components, reducing the local pressure peak and preventing the aggregate from piling up and blocking the pipe.

[0052] Furthermore, the pitch of the spiral diversion groove 121 is 1.5-2 times the diameter of the conduit 100. If the pitch is too small, the resistance is easily increased, and if it is too large, the diversion effect is weakened. At the same time, in order to balance the diversion effect and the structural strength, the depth of the diversion groove is 3-5 mm.

[0053] It should be noted that when the concrete is being poured through the conduit 100, a casing module 130 can be provided outside the conduit 100. The casing module 130 is a double-layer steel cylinder structure. The outer layer 131 is a porous filter cylinder, and the inner layer 132 is a smooth retaining wall cylinder. A degradable slurry material is filled between the two layers. Among them, the porous filter cylinder of the outer layer 131 allows the slurry to penetrate but blocks the soil particles, maintaining the stability of the pile hole. The smooth retaining wall cylinder of the inner layer 132 can reduce the flow resistance of the concrete and prevent the collapse of the hole wall. And the degradable slurry material fills the gap between the pile hole and the casing, forming a flexible sealing barrier. It can solve the problem that the traditional casing cannot adapt to the loose stratum and significantly reduce the risk of pile hole collapse.

[0054] For example, in some embodiments, the degradable slurry material can be a water-swellable gel. Among them, the swelling rate of the gel layer after encountering water can reach 300%-500%, and the sealing pressure can be automatically adjusted according to the groundwater level or the hardness of the soil. And the gel material is a biodegradable polymer, which degrades naturally after construction and avoids pollution.

[0055] It should be noted that the casing module 130 is quickly disassembled through a snap structure, thereby improving the reuse rate of the casing module 130.

[0056] In some embodiments, the concrete pumping unit 200 includes a variable-frequency motor 210, a two-way hydraulic pump 220 linked with the variable-frequency motor 210, and a conveying pipeline 230 wrapped with a heat-insulating layer 231. The conveying pipeline 230 is hermetically connected to the top of the conduit 100 through a flange.

[0057] It is understandable that the concrete pumping unit 200 can pump concrete through the conveying pipeline 230 into the conduit 100 to achieve the pouring treatment of the cast-in-place pile. Among them, it is allowed to wrap a heat-insulating layer 231 on the outer wall of the conveying pipeline 230 of the concrete pumping unit 200, and internally integrate heating resistance wires for the constant-temperature conveying of concrete in low-temperature environments, thereby improving the applicability of the device.

[0058] In some embodiments, the conduit 100 is connected to the pile frame support unit 300, and the pile frame support unit 300 includes a support frame 320 with a lifting mechanism 310 and a conduit 100 fixing clamp 330 integrated with an inclination sensor. The fixing clamp 330 is hinged to the support frame 320 and dynamically adjusts the verticality of the conduit 100 through a servo motor. The integrated inclination sensor can be used to detect the angle of the conduit 100 in real time to facilitate the angle adjustment of the conduit 100. At the same time, for the fixing clamp 330, it is allowed to be determined according to the actual situation.

[0059] It should be noted that in some embodiments, the lifting mechanism 310 can be hydraulically driven. At the same time, the pile frame support unit 300 further includes at least a mounting frame 340, and the mounting frame 340 is a detachable frame structure. This is to facilitate the disassembly and transportation of the mounting frame 340. At the same time, the lifting mechanism 310 is connected between the support frame 320 and the mounting frame 340. The mounting frame 340 serves as a fixed unit module, and the support frame 320 serves as a mobile unit module. The height adjustment of the guide rod is achieved through the lifting mechanism 310.

[0060] In some embodiments, the intelligent control unit 400 includes a distributed pressure sensor group 410, a multi-modal burial depth detection module 420, and a central controller 430. It is understandable that the distributed pressure sensor group 410 and the multi-modal burial depth detection module 420 are electrically connected to the central controller 430, and the central controller 430 is allowed to obtain corresponding monitoring data through the distributed pressure sensor group 410 and the multi-modal burial depth detection module 420. At the same time, the intelligent control unit 400 further includes a wireless communication module, which is used to connect to a remote monitoring terminal and transmit construction data.

[0061] Furthermore, the distributed pressure sensor group 410 includes multiple sensors, and the sensors are distributed at the bottom, middle, and inside the transportation pipeline of the conduit 100. The distributed pressure sensors can be used to detect the pressure distribution of the concrete, and thus determine the real-time state of the concrete in the conduit 100 and the transportation pipeline.

[0062] Among them, the multi-modal burial depth detection module 420 includes an integrated laser rangefinder 421 and an ultrasonic sensor 422, which are used to detect the depth of the catheter 100 buried in the concrete and the height of the concrete liquid level in the pile hole in real time. Specifically, the integrated laser rangefinder 421 can be connected to the side wall of the catheter 100 or the fixing fixture 330 of the catheter 100 to measure the height of the concrete liquid level in the pile hole. At the same time, the depth of the catheter 100 buried in the concrete is obtained through the ultrasonic sensor 422.

[0063] It can be understood that a concrete rheology model can be set in the central controller 430, and the concrete rheology model can be used to predict the segregation risk. At the same time, the central controller 430 also dynamically adjusts the rotation speed of the variable frequency motor 210 and the lifting speed of the catheter 100 according to the sensor data. By adjusting the rotation speed of the variable frequency motor 210 and the lifting speed of the catheter 100, the actual pouring effect of the cast-in-place pile can be improved.

[0064] In some embodiments, when the central controller 430 dynamically adjusts the rotation speed of the variable frequency motor 210 and the lifting speed of the catheter 100 according to the sensor data, it includes:

[0065] And

[0066] Where v 1 represents the rotation speed of the variable frequency motor, e(t) represents the deviation between the target pressure and the actual pressure, and K p , K i and K d are correction parameters; v 2 represents the lifting speed of the catheter, Q represents the concrete pumping flow rate, r represents the radius of the pile hole, and K 2 represents the safety factor.

[0067] It can be understood that precise control can be achieved through the linear combination of multiple parameters.

[0068] For example, in the deep burial control of the catheter 100 in the pile hole, its input is the deviation between the target pressure and the actual pressure, and the output is the rotation speed command of the variable frequency motor. Among them, for K p , K i and K d the correction parameters can be obtained by looking up a table. For example, in an implementation scheme, K p = 1.2, K i = 0.1, and K d = 0.2 are the correction parameters.

[0069] It should be noted that, in order to improve the pouring effect of the cast-in-place pile during the actual pouring process, the central controller 430 may allow the prediction of segregation risk based on the concrete rheological model, and dynamically adjust K based on a preset dynamic adjustment comparison table. p K i and K d coefficients, and then realize the adaptive adjustment of the rotational speed of the variable-frequency motor. For example, when the formation resistance increases, reduce K p to avoid overshoot; when the risk of pipe blockage is detected, increase K d to quickly suppress pressure fluctuations.

[0070] Based on this, please refer to Figure 7 This invention also provides a usage method of a cast-in-place pile perfusion device for construction applying the above-mentioned embodiments, which includes the following steps.

[0071] Step S1: Fix the conduit 100 vertically at the center of the pile hole through the pile frame support unit 300, and install the casing module 130 to the target formation depth.

[0072] Step S2: Start the concrete pumping unit 200, set the initial pumping pressure through the intelligent control unit 400, and inject the concrete into the bottom of the pile hole through the conduit 100.

[0073] It should be noted that, in order to improve the actual effect of the cast-in-place pile, the slump of the concrete can be controlled within 180 - 220 mm. For this purpose, a thickening agent can be added to reduce the segregation risk.

[0074] Step S3: Obtain the concrete flow state data through the pressure sensor 410 and the buried depth detection module 420, and the central processor 430 dynamically adjusts the pumping speed and the lifting speed of the conduit 100 to keep the buried depth of the conduit 100 within the range of 2 - 6 meters.

[0075] Step S4: When the height of the concrete poured in the pile hole reaches the preset value, disassemble the conduit 100 in sections and continue pouring until the pile top elevation.

[0076] Step S5: After the pouring is completed, remove the casing module 130, and clean the residual concrete in the conduit 100 and the concrete pumping unit 200.

[0077] In summary, the present invention provides a pouring pile perfusion device for construction and its usage method. The central controller monitors in real time and dynamically adjusts the pumping speed, the lifting speed and the verticality of the conduit, reducing manual intervention and thus effectively shortening the construction time. The anti-friction coating inside the conduit can effectively reduce the flow resistance of the concrete and improve the accuracy of the test data. In addition, the conduit end located at the end of the conduit is provided with a spiral diversion groove, which can effectively optimize the concrete flow path and reduce the segregation rate of the concrete. At the same time, according to the depth and diameter of the pile hole, the concrete pumping speed is reasonably controlled to avoid being too fast or too slow. Furthermore, continuous pouring of the concrete is ensured to avoid pile body defects. The present invention significantly improves the construction efficiency, the quality of the pile foundation and the adaptability to complex geology, while reducing the construction cost and risk, and has broad application prospects and economic benefits.

[0078] Therefore, the present invention effectively overcomes some practical problems in the prior art and thus has high utilization value and practical significance.

[0079] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
