Description

Technical Field

[0001] This invention belongs to the field of bag pile and bag installation technology, and more specifically, relates to an automated bag pile and bag installation system and its construction method. Background Technology

[0002] The geotextile-lined concrete pile with geotextile bag casing (commonly known as "geotextile bag pile") is an important new technology and achievement in pile foundation engineering for corrosive and karst areas. Developed from the original concrete pile, its structure includes a concrete pile body containing a reinforcing cage. The outer surface is wrapped with a composite geotextile bag material with excellent waterproof and corrosion-resistant properties (two layers of geotextile bag and one layer of geomembrane) to isolate corrosive substances from penetrating the pile body and prevent concrete from flowing into the karst cave. The composite geotextile bag is made by hot-pressing or welding two layers of polyethylene geotextile bags with a geomembrane sandwiched in between. The construction method involves, after borehole drilling and acceptance, covering the reinforcing cage with the geotextile bag, lowering it into the pile hole, and then lowering the tremie pipe for concrete pouring.

[0003] Current technology for installing steel bag piles typically involves using a crane to lift the reinforcing cage, followed by construction workers carefully placing the fabric bag over it. This process is not only labor-intensive but also prone to worker fatigue and increases the risk of operational errors. In complex geological conditions such as corrosive or karst areas, the harsh working environment can negatively impact worker health due to prolonged exposure. Furthermore, the installation of the fabric bag requires manual operation in conjunction with the crane, making the process complex and time-consuming, severely impacting the overall construction progress of the pile foundation project. This inefficiency can lead to delays and increased costs, especially in large-scale projects. During manual installation, the fabric bag is easily damaged by friction and impact, affecting its waterproof and corrosion-resistant properties. For example, workers may accidentally tear the bag while placing it, rendering it ineffective. Precise positioning of the fabric bag is difficult to control, leading to issues such as loose fit between the bag and the reinforcing cage, and wrinkles in the bag, all of which affect the overall performance and lifespan of the steel bag pile. Therefore, current technology for installing steel bag piles suffers from time-consuming and difficult installation methods.

[0004] While existing technologies offer some improvements, limitations remain. Some employ folded steel reinforcement cages with enlarged ends on the bag, which, after being lowered and grouted, pulls the steel reinforcement cage to unfold and form a reinforced concrete bag pile. While this addresses the difficulties of pile formation in karst areas and the poor stability after pile formation, it is only applicable to folded steel cages and not to conventional steel cages, failing to solve the problems of high installation difficulty and long installation time associated with conventional steel cages. Other technologies use variable cross-section steel reinforcement cage bag pile structures, including a steel cage, grouting pipes inserted within the steel cage, and a bag fitted outside the steel cage, with auxiliary support structures on the steel cage. While this addresses the technical problem of structural instability during construction, leading to bag swaying during cement grouting and consequently structural instability, it is only applicable to variable cross-section steel cages and not to conventional steel cages, failing to solve the problems of high installation difficulty and long installation time associated with conventional steel cages. Other methods employ a steel cage composed of several supporting longitudinal bars and connecting longitudinal bars. The top and bottom outer sides of the steel cage are fitted with annular fixing stirrups for fixation. The steel cage contains an expansion and contraction control device and several deformable stirrups. The expansion and contraction control device connects to the deformable stirrups to change the cross-section of the steel cage. However, this method is only applicable to variable cross-section steel cages and cannot be used with conventional steel cages, failing to solve the problems of high installation difficulty and long installation time associated with conventional steel cages and their fabric bags. Existing technologies lack versatility and cannot adapt to steel cages and fabric bags of different lengths and specifications, leading to the need for multiple adjustments and improvements for different construction scenarios in practical applications, increasing construction complexity and cost.

[0005] In summary, existing technologies have many shortcomings in terms of construction efficiency, labor intensity, installation accuracy, applicability, construction quality, and safety risks. Summary of the Invention

[0006] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an automated installation system and method for steel cage piles and their fabric bags. By integrating a steel cage lifting mechanism, a fabric bag traction mechanism, and a traction control device into a single unit, the system uses two lifting mechanisms to raise the steel cage and fabric bag to a certain height. The fabric bag traction mechanism then rapidly pulls the fabric bag from one end to the other of the steel cage, achieving synchronous lifting and automated installation of the steel cage and fabric bag. By incorporating multiple sensors within the system to monitor parameters such as lifting height, traction position, traction force, and tilt angle in real time, the system ensures the accuracy and stability of the installation process. This addresses the problems of high installation difficulty, long installation time, and excessive reliance on manual labor associated with conventional steel cage and fabric bag installation. Compared to existing technologies, this invention significantly improves construction efficiency, reduces labor intensity and construction risks, protects the integrity of the fabric bag, and enhances construction quality, demonstrating promising application prospects and economic benefits.

[0007] To achieve the above objectives, one aspect of the present invention provides an automated installation system for steel cage piles, comprising a steel cage lifting mechanism, a steel cage traction mechanism disposed on the steel cage lifting mechanism, and a traction control device connected to the steel cage lifting mechanism and the steel cage traction mechanism; wherein...

[0027] A second aspect of the present invention provides a construction method for an automated installation system for baghouse piles, which is implemented using the aforementioned automated installation system and includes the following steps:

[0028] S1: Place the steel cage and the cloth bag in a straight line on a flat and solid ground. Place the first hoist at the end of the steel cage away from the cloth bag and the second hoist at the end of the cloth bag away from the steel cage. Place a winch on top of the first hoist.

[0031] S4: Connect the first hoist, the second hoist, and the winch to the traction control device; the traction control device extends the jacks in the two hoists, driving the connecting rod assembly upwards to raise the rebar cage and the cloth bag to a certain height above the ground; during the lifting process, the traction control device adjusts the extension speed and torque of the jacks in real time based on feedback signals from the displacement and angle sensors to ensure the rebar cage and cloth bag are lifted smoothly and the rebar cage remains horizontal; the traction control device retracts the traction rope of the winch, thereby pulling the cloth bag to slide along the outer surface of the rebar cage away from the end where the cloth bag is located; during the traction process, the traction control device adjusts the traction speed and torque of the winch in real time based on feedback signals from the position and force sensors to ensure the cloth bag can smoothly and evenly cover the rebar cage; when the cloth bag completely covers the rebar cage, the traction control device automatically controls the winch to stop working;

[0034] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0035] (1) The automated installation system and method for bag piles of the present invention uses lifting mechanisms at both ends and is connected by a connecting rod assembly. The connecting rod assembly passes through the center of the steel cage and the bag, raising the steel cage and the bag to a certain height. This solves the problem that the ropes will hinder the smooth installation of the bag when the crane lifts the steel cage in the traditional installation process, thereby realizing the convenient installation of the steel cage and the bag, significantly improving the installation efficiency, reducing the installation difficulty, and bringing great convenience to the construction of bag piles.

[0036] (2) The automated installation system and construction method for steel cage piles of the present invention achieves synchronous lifting and automated installation of the steel cage and the steel bag through the coordinated work of the steel cage lifting mechanism and the steel bag traction mechanism. Compared with the existing technology that relies on manual labor and cranes to install the steel bags, the automated system of the present invention greatly reduces the complexity and time consumption of manual operation. Through the precise control of the traction control device, the installation process of the steel cage and the steel bag is more efficient, and the installation time can be shortened by more than 50%, significantly improving the construction progress, especially in large-scale pile foundation projects.

[0037] (3) In the prior art, the installation of bag piles usually requires a large amount of manual labor in conjunction with crane operation, which is labor-intensive and inefficient. The automated bag pile installation system and construction method of the present invention, through automated equipment and control devices, reduces manual intervention, lowers labor intensity, and avoids errors and safety hazards that may occur in manual operation. The use of the automated system not only improves the safety and comfort of construction, but also reduces the risk of construction accidents caused by human factors, further enhancing the overall safety of the construction site.

[0038] (4) The automated installation system and construction method for bag piles of the present invention integrates multiple sensors (such as position sensors, force sensors, and angle sensors) to monitor the lifting height, traction force, and installation position of the reinforcing cage and bag in real time, ensuring the accuracy and stability of the installation process. Through automated traction and control devices, friction and damage to the bag during installation are avoided, ensuring the integrity and waterproof and corrosion-resistant performance of the bag. Furthermore, through optimized bag traction mechanisms and traction control devices, the bag can be precisely installed outside the reinforcing cage, improving installation accuracy and construction quality, extending the service life of the bag piles, and providing a guarantee for the long-term stability of the pile foundation project.

A force sensor is installed between the jacks 112 and the connecting disc 113 to monitor the lifting force of the jacks. The installation of the force sensor needs to be based on the working principle of the machine and the force distribution to select a suitable position to ensure that the sensor can accurately measure the force value; additional mechanical stress should be avoided during installation to ensure the measurement accuracy of the sensor. An angle sensor is provided on the top of the jacks 112 or on the connecting disc 113 to monitor the tilt angle of the rebar cage and bag during installation to ensure the stability of the installation.

[0061] like Figure 6 As shown, a second aspect of the present invention provides an automated installation method for bag-laying piles, comprising the following steps:

[0062] S1: Arrangement of the steel cage lifting mechanism 1 and the bag traction mechanism 2: Place the steel cage 4 and the bag 5 in a straight line on a flat and solid ground, ensuring that the center line connecting the steel cage and the bag is parallel to the ground; place the first hoist 11 at the end of the steel cage 4 away from the bag 5, and place the second hoist 12 at the end of the bag 5 away from the steel cage 4; place the winch 21 on top of the first hoist 11; install and fix the ring 22 on the bag 5 near the end of the steel cage 4, and install the ball 23 with the insertion hole at the end of the steel bar of the steel cage 4 near the end of the bag 5; the balls should be evenly distributed on the edge of the end of the steel cage.

[0063] S2: Connection of connecting rod assembly 13: Determine the number of intermediate connecting rods 132 according to the length of the steel cage 4 and the cloth bag 5; assemble the intermediate connecting rods 132 and the end connecting rods 131 through the screw and sleeve; pass the assembled connecting rod assembly through the center of the steel cage 4 and the cloth bag 5, and insert the end connecting rods 131 at both ends into the connecting disc 113 of the hoist, ensuring that the insertion is tight and without looseness; connect the ring 22 on the cloth bag 5 to the winch 21 through the traction rope 24; the traction rope 24 should be taut, but not excessively stressed;

[0064] S3: Sensor Installation and Debugging: Install a displacement sensor on the top of the jack 112 or on the connecting disc 113 to monitor the lifting height of the rebar cage; install a position sensor and a force sensor on the traction rope 24 of the winch 21 to monitor the traction position and traction force of the cloth bag; install a force sensor between the jack 112 and the connecting disc 113 to monitor the lifting force of the jack; install an angle sensor on the top of the jack 112 or on the connecting disc 113 to monitor the tilt angle of the rebar cage 4 and the cloth bag 5 during installation; debug each sensor to ensure that it can accurately collect data and transmit it to the traction control device 3;

[0065] S4: Lifting and Traction: Connect the first hoist 11, the second hoist 12, and the winch 21 to the traction control device 3 respectively; the traction control device 3 extends the jacks 112 in the two hoists, driving the connecting rod assembly 13 upward, raising the steel cage 4 and the cloth bag 5 to a certain height above the ground; during the lifting process, the traction control device adjusts the extension speed and torque of the jacks in real time according to the feedback signals of the displacement sensor and the angle sensor to ensure that the steel cage and the cloth bag are lifted smoothly and the steel cage remains horizontal; the traction control device 3 retracts the traction rope 24 of the winch 21, thereby pulling the cloth bag 5 to slide away from the end of the steel cage 4; during the traction process, the traction control device 3 adjusts the traction speed and torque of the winch 21 in real time according to the feedback signals of the position sensor and the force sensor to ensure that the cloth bag 5 can smoothly and evenly cover the steel cage 4, and the traction force is moderate to avoid damage to the cloth bag 5; when the cloth bag 5 completely covers the steel cage 4, the traction control device 3 automatically controls the winch to stop working.

[0066] S5: Equipment Disassembly and Transfer: Untie the traction rope 24 between the ring 22 installed on the cloth bag 5 and the winch 21, and shorten the jacks 112 in the hoists at both ends to the shortest length using the traction control device 3, and place the steel cage 4 with the cloth bag 5 installed on it on the ground; move the connecting rod assembly 13 to the left or right to disconnect it from the hoist and pull it out of the steel cage; move the equipment to the next steel cage 4 and cloth bag 5.

[0067] S6: Repeat steps S1-S5 to continue installing the cloth bag 5 on the steel cage 4.

[0068] Furthermore, step S5 also includes post-installation inspection, such as visual inspection: checking whether the bag completely covers the reinforcing cage, whether the surface is flat, without wrinkles or damage, and whether the bag and the reinforcing cage are tightly fitted. Quality inspection: using non-destructive testing methods to inspect the quality of the bag piles to ensure that the waterproof and corrosion-resistant performance of the bag meets the requirements and that the structure of the reinforcing cage is not damaged. Site cleanup: cleaning the construction site, properly storing any remaining materials and equipment, and ensuring that the construction site is clean and safe.

[0069] The automated installation system and construction method for steel bag piles provided by this invention utilizes lifting mechanisms at both ends connected by connecting rods. The connecting rods pass through the center of the steel cage and the bag, raising both the steel cage and the bag to a certain height. This solves the problem of ropes obstructing the bag installation when the crane lifts the steel cage, thus facilitating the installation of the steel cage and bag. By setting up a bag traction mechanism, a winch retracts the rope, quickly pulling the bag from one end to the other of the steel cage, solving the problem of long installation times for workers assisting with crane installation and significantly shortening the installation time. Furthermore, by installing and fixing a ring on the end of the bag near the steel cage, and installing a ball with a hole at the end of the steel reinforcement near the bag, the system solves the problems of damage to the bag due to collisions between the bag and the reinforcement, and the bag's obstruction during installation. This achieves cost savings and accelerates the installation speed of the steel cage and bag. By coordinating the lifting mechanism, the bag traction mechanism, and the traction control device, the synchronous lifting and automated installation of the rebar cage and bag can be achieved. This solves the problem of low efficiency in bag installation for workers, achieving high-speed and efficient automated installation of the rebar cage and bag. The automated equipment and control devices significantly reduce manual intervention and labor intensity. The use of this automated system not only improves construction safety and comfort but also reduces the risk of construction accidents caused by human factors. By installing displacement and angle sensors on the top of the jacks and the connecting disc, the system can monitor the lifting height and tilt angle of the rebar cage in real time, ensuring the smoothness and accuracy of the lifting process. During bag traction, by installing position and force sensors on the winch's traction rope, the system can monitor the traction position and traction force of the bag in real time, preventing damage to the bag due to uneven force during traction. These automated control measures not only improve installation efficiency but also ensure the safety and reliability of the construction process, further enhancing the overall safety of the construction site.
