[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1-4, an information management system for dynamic tamping construction, including a tamping hammer 6, a microcomputer and a handheld terminal. A counterweight groove 5 is provided on the upper part of the tamping hammer 6. There are multiple groups of counterweight grooves 5, which are evenly arranged on the side wall of the tamping hammer 6. The center of gravity of the tamping hammer 6 is adjusted downward, the upper part is light and the lower part is heavy, so as to improve the falling stability of the tamping hammer 6 and avoid the tamping pit being uneven due to a large tilt when the tamping hammer 6 falls. There are mounting holes in the counterweight groove 5 for easy installation of the counterweight block and center of gravity adjustment. The handheld terminal is used to receive construction measurement information and feedback information of the dynamic tamping machine construction, so as to improve the efficiency of construction site management; The handheld terminal is connected to the GPS satellite positioning system, which is used to assist in the synchronous layout of the elevation control network and the plane control network; To prevent errors, as important measurement points such as control centerline piles and leveling points during construction, at least two groups must be set up for mutual inspection and verification, and measurement and inspection and verification records must be made. The arranged control piles should be stable and reliable and retained until the end of the project; For the convenience of protection, the construction leveling points are as consistent as possible with the plane control points. Basic leveling points and temporary leveling points are used for two-level layout. The basic leveling points are the main control points for controlling the entire construction area. Second-class leveling is used for joint measurement with the provided leveling points. Temporary leveling points are densely laid out according to the needs of layout. Construction measurement information includes surface settlement, pore water pressure, groundwater level, deep horizontal displacement, tamping amount and uplift amount. After each tamping, a steel tape measure is used in conjunction with other instruments to measure the tamping amount and uplift amount of each tamping point, and the information is entered into a handheld terminal for information management. The construction measurement information comes from the water body measurement module 1 and the terrain measurement module 2. The water body measurement module 1 is used to monitor the state of the groundwater body and the changing characteristics of the groundwater level during the compaction process, which serves as the data basis for the foundation dewatering work before the compaction construction. The water body measurement module 1 includes a 2-wave echo sounder, a groundwater level meter and a pore water pressure meter. The 2-wave echo sounder is used to detect the water depth of the foundation and provide high-precision water depth measurement data. The groundwater level meter is used to detect the water content of the foundation and feedback the progress of vacuum dewatering construction. The pore water pressure meter is used to observe the dissipation of excess pore water pressure to facilitate the determination of the strong compaction construction period. Before the strong compaction construction, it is necessary to ensure that the groundwater level is 2.5m below the tamping surface and that the excess pore water pressure in the soil body is dissipated by more than 80%; The topographic measurement module 2 includes a theodolite, a level, a total station and an inclinometer. The topographic measurement module 2 is used to detect the initial conditions of the construction site in order to preliminarily determine and adjust the dynamic compaction construction parameters. Data feedback is performed during the construction process, including vertical displacement monitoring, horizontal displacement monitoring and deep soil displacement monitoring of the foundation, so as to dynamically adjust the construction parameters according to the construction effect. Among them: The vertical displacement monitoring projects include the surface settlement of the high vacuum densification area, the vertical settlement of the wharf structure, the vertical settlement of the high-pressure swing spray pile and cement mixing pile, and the settlement of the top of the harbor and foundation pit slope. The horizontal displacement monitoring projects include the deep horizontal displacement of the high vacuum densification area, the horizontal displacement of the wharf structure, the surface and deep horizontal displacement of the high-pressure swing spray pile and cement mixing pile, and the displacement of the top of the harbor and foundation pit slope. Construction measurement is carried out according to the construction site, construction control network and design drawings to carry out positioning and elevation measurement; according to the design drawings and the control point coordinates provided by the owner, the positioning and layout data of the construction control line are calculated; when measuring and laying out, the orientation of the construction control line is controlled, the plane position is controlled with a total station, and the template support is controlled with a theodolite and level to ensure the straightness of the axis. The construction fixed-point layout is carried out with a total station; During the construction process, the baseline and leveling points must be checked regularly or irregularly and properly protected. If any deviation or damage is found, the cause must be investigated and restoration must be carried out in a timely manner.

[0019] The dynamic compaction machine construction feedback information is used to monitor the working status of the dynamic compaction machine and ensure the reliability and safety of the construction. The dynamic compaction machine construction feedback information comes from the inclination sensor and tension sensor, as well as the inspection of the tamping pit and foundation by on-site inspection personnel; The microcomputer is connected to the handheld terminal for communication. The microcomputer is connected to the rammer stabilization component 3 and the unhooking device control module 4. The inclination sensor is arranged on the rammer 6. The inclination sensor is used to measure the horizontal angle change of the rammer 6 as the basis for adjusting the rammer stabilization component 3. The rammer stabilizing assembly 3 is used to maintain the balance of the rammer 6 to avoid a large angle of tilt during the falling process, which affects the accuracy of the strong tamping. The rammer stabilizing assembly 3 is arranged on the rammer 6. The rammer stabilizing assembly 3 includes a control solenoid valve and an oil pump 32. A liquid storage tank 31 is provided in the middle of the rammer 6. A counterweight box 33 is provided on the upper surface of the rammer 6. An oil pipe 34 is provided between the liquid storage tank 31 and the counterweight box 33. The control solenoid valve and the oil pump 32 are both arranged on the oil pipe 34. There are multiple groups of counterweight boxes 33, which are evenly arranged on the upper side of the rammer 6. The liquid storage tank 31 and the counterweight box 33 are filled with oil. The bottom of the counterweight box 33 is conical or hemispherical, which is convenient for gathering oil and avoiding the flow of oil to affect the stability of the center of gravity. When the rammer 6 falls and tilts, the inclination sensor collects relevant data, which is collected by the microcomputer and an adjustment instruction is issued to control the solenoid valve and the oil pump 32 to start working, pumping oil, adjusting the amount of oil in each counterweight box 33, changing the counterweight, and adjusting the center of gravity; The unhooking device control module 4 is used to control the rammer 6 to fall reliably during strong tamping, and to prevent the rammer 6 from being unhooked when lifting and suspending the rammer 6, thereby improving construction safety. A hanging ring 61 is provided on the top of the rammer 6, and the unhooking device control module 4 includes a main body 41, a telescopic rod 43 and a hook 44, and the hook 44 is arranged corresponding to the hanging ring 61; the hook 44 is rotatably connected to the main body 41, and the two ends of the telescopic rod 43 are respectively rotatably connected to the hook 44 and the main body 41, and a hanging rod 42 is provided on the top of the main body 41.

[0020] The tilt sensor can be replaced by a gyroscope to collect horizontal, vertical, pitch, heading and angular velocity information; The tension sensor is arranged on the suspension rod 42 to detect the tension carried by the suspension rod 42 and determine the suspension state of the rammer 6.

[0021] Specific construction steps: (1) Configure equipment, prepare for construction, conduct geological survey of the site, determine the construction plan, and then level and backfill the site; (2) During the process of measuring and arranging control points, comprehensive consideration should be given to factors such as the control points should be convenient for construction, good visibility on site, stable and reliable foundations at the points, not prone to displacement, settlement, or damage, and easy to protect. During construction, temporary control points can be added according to the needs of the project construction, and their accuracy should meet the corresponding grade requirements; (3) Dig drainage ditches, arrange well point locations, prepare for vacuum well point dewatering, install equipment corresponding to the vacuum well point dewatering system, insert pipes to arrange dewatering pipes, configure pump rooms, and connect pipelines; When vacuum drainage is carried out, continuous pumping should be ensured when the vacuum system is in operation. During the drainage process, a 2-wave echo sounder, groundwater level meter and pore water pressure meter should be used to detect the groundwater body, and timely feedback on the construction effect should be given to improve the construction efficiency; (4) Four times of spot tamping and two times of full tamping. After the spot tamping is completed, all downpipes are removed and full tamping is performed. Full tamping is lap tamping with an lap width of 1 / 4 of the hammer diameter. The full tamping energy is set at 800 kJ and the number of hits per pass is 2. The interval time between each strong compaction should be strictly controlled by test compaction and information technology, and adjusted according to the on-site test results; the settlement amount of each blow is calculated by measuring the change in the height of the top surface of the hammer; a dedicated person uses a level to measure and record each blow, and then calculates the single-blow settlement amount and makes detailed records; the next point can be constructed only when the stop-blow standard is met; Steps of compaction construction: ① Mark the location of the first compaction point and measure the original ground elevation; ② Put the crane in place and align the center of the tamping hammer with the tamping point; ③Measure the elevation of the hammer top before tamping; After the hammer weight and lifting height are determined according to the test section, a fixed ruler is set on the crane to determine the elevation; the subsequent construction is carried out according to the construction method of the first strike; when the hammer withdrawal standard is reached, the tamping of the point is stopped, and the tamping of the point is completed; the surveyor calculates the average of the last two strikes of the tamping point and fills it in the record sheet; the tamping machine lifts the hammer and moves to the next tamping point and the construction is carried out in sequence according to the construction method of the first point; The tamping process needs to observe, record and analyze the number of tamping times at each tamping point, the tamping amount per tamping, the average tamping amount of the final two tampings, the cumulative tamping amount (tamping pit depth), and the tamping pit diameter; ④ Lift the rammer to the predetermined height, lower the hook after the rammer falls off and falls freely, and measure the elevation of the top of the rammer; if it is found that the rammer is tilted due to the tilt of the pit bottom, use a bulldozer in time to fill the pit bottom with silt or silty clay from the excavated earthwork of the harbor basin; ⑤ Repeat step ④ to complete the tamping of one tamping point according to the tamping times and control standards required by the design; The point tamping adopts the step-by-step tamping method. The tamping energy is set to 1000kJ, 1400kJ, 1800kJ, and 2200kJ according to the test area. The number of hits per pass is set to 6. The spacing between tamping points is 4.0m and they are arranged in a square. ⑥Change the tamping point and repeat steps ③ to ⑤ to complete the tamping of all tamping points in the first round; Firstly carry out spot tamping test construction according to the construction parameters, and the specific number of hits and energy need to be adjusted in combination with the on-site test tamping results; Stop hammer standard: The average tamping amount of the last two hits of a single point should not exceed 5cm, the ground around the tamping pit should not bulge too much, and the hammer should not be difficult to control due to the tamping pit being too deep; ⑦Complete the four-time spot tamping construction according to the above steps; In order to avoid the soil from being damaged by being beaten into "spring soil", there should not be too much bulge between ramming pits. The equipment is used to measure the bulge of the pit edge at 0.5m, 1.0m and 1.5m outside the pit in two orthogonal directions of each test ramming pit. With the help of a microcomputer, a curve of the relationship between the number of blows N and the amount of ramming S is drawn to calculate the bulge and side squeeze, determine the best ramming energy, and adjust the lifting height of the rammer. ⑧ After the last round of tamping, remove the vacuum tube in the site, flatten the site with a bulldozer, and then use low-energy full tamping to compact the surface soil of the site, and measure the site elevation after tamping; (5) Site leveling, equipment dismantling, and project acceptance; After each process is completed, the technical personnel and quality inspectors in charge of the process will organize the construction area manager to conduct inspections according to the relevant strike count specifications, and conduct construction quality inspections based on the process parameters in the microcomputer to effectively prevent bad behavior and ensure construction quality.

[0022] In addition, dynamic compaction construction cannot be carried out on rainy days. The site must be effectively drained after rain and the groundwater must be tested. After drainage, dynamic compaction can be carried out. During the construction process, the precipitation pipes that affect the movement of the tamping machine will be removed, and as few precipitation pipes as possible should be removed.

[0023] During the compaction process, check whether the rammer is in the center to ensure that the compaction point is accurate. If there is eccentricity, add counterweights to balance it and prevent the ramming pit from tilting excessively. During this process, when the tilt angle of the rammer 6 is too large, it affects the reliability of the tamping construction. The rammer stabilizing component 3 starts to work and begins to intervene in the control. The inclination sensor detects the tilt angle of the rammer 6. The microcomputer controls the solenoid valve and the oil pump 32 to start working according to the corresponding data, adjusts the oil distribution, improves the counterweight, and ensures that the rammer 6 tamps the soil stably.

[0024] The microcomputer can also be connected to a display and an alarm. The display is used to prompt the operator to operate according to instructions, improve the standardization and informatization of construction, and make timely adjustments based on feedback from construction measurements. The alarm is used to remind construction personnel or other personnel on site that tamping construction is in progress, and remind personnel to take shelter in time to improve safety.
