s1, establishing the vibroflotation pile encryption quality intelligent control model, wherein the step of establishing the vibroflotation pile encryption quality intelligent control model comprises the following steps: the method comprises three aspects of vibroflotation 6 working parameter control, vibroflotation 6 space attitude control and backfill material control, and provides theoretical and technical support for establishing an intelligent vibroflotation pile encryption control system based on real-time monitoring and feedback of the whole vibroflotation pile encryption process;
the basic outline of the main detailed engineering of each control module is as follows:
vibroflotation site: soft soil layer under deep covering layer riverbed
Vibroflotation depth: about 30m
Power of vibroflot 6: 220kW
Backfilling: graded broken stone 10
The construction method comprises the following steps: operated manually
The encryption quality judgment method comprises the following steps: manual experience control;
s2, obtaining working parameters of the vibroflot 6, where the step of obtaining working parameters of the vibroflot 6 includes: the vibroflotation device 6 comprises the current intensity, the vibration retention time, the vibroflotation water pressure, the vibroflotation air pressure and main working parameters which have important influence on the vibroflotation encryption quality in the encryption process;
the current intensity, or encryption current, refers to the designed current value that the motor of the vibroflotation device 6 needs to reach in the process of vibroflotation soil or filler pile making, and mainly refers to that the vibroflotation encryption process should not be less than the set minimum current intensity, too small current reduces vibroflotation encryption work efficiency, insufficient compaction strength to broken stones and strata, too large current easily damages the motor of the vibroflotation device 6, reduces the service life of the motor, and the like. Therefore, the current intensity is required to set a normal working threshold value according to the rated power of the motor of the vibroflot 6 and the stratum condition;
if the rated power of a motor of the vibroflot 6 is 220kW, the encrypted stratum is silty clay, and the threshold value of the normal working current intensity can be set as follows: 220A to 250A.
The vibration remaining time refers to the duration of the electric motor of the vibroflot 6 for maintaining the encrypted current in the process of compacting soil or filling and pile making. In the encryption process, the sufficient vibration remaining time is a control index for ensuring that the vibroflot 6 fully vibrates and compacts the soil mass and the crushed stones, so the minimum vibration remaining time needs to be set;
the setting of the vibration retention time can be determined by combining a field pile test, the type of the vibroflot 6, the stratum condition and the design requirement, and can be set to 20 s-30 s under the general condition.
The vibroflotation water pressure refers to the water outlet pressure at the top of the vibroflotation device 6 in the encryption process of the vibroflotation device 6. The vibroflotation method is also called as a vibroflotation method, pressure water is used for assisting in construction in a wet vibroflotation process, under the impact of high-pressure water, the vibroflotation method is beneficial to the implementation of pore-forming and encryption, and simultaneously can play a role in cooling the vibroflotation device 6 to ensure that the machines and tools operate normally;
the water pressure in the vibroflotation encryption process is controlled by the type 6 of the vibroflotation device and the stratum condition, can be determined by combining a field pile test, and can be generally set to be 0.1 MPa-0.5 MPa.
The vibroflotation water pressure refers to the air pressure at the top of the vibroflotation device 6 in the encryption process of the vibroflotation device 6. The air pressure is increased into the pile from the bottom of the vibroflotation device 6 in the encryption process, so that the balance of the air pressure inside and outside the pile is kept, and the phenomenon of deformation (necking) of the pile body due to the overlarge air pressure difference inside and outside the pile body is avoided;
the air pressure value is determined according to geological conditions and combined with a field test pile test, can be equal to or slightly greater than the water pressure value, and can be generally set to be 0.1 MPa-0.5 MPa;
s3, obtaining real-time working parameters of the vibroflot 6 according to the working parameters of the vibroflot 6 and a vibroflot 6 space attitude control module, wherein the vibroflot 6 space attitude control module consists of the verticality, the depth, the encryption descending speed, the encryption ascending speed, the length of a primary encryption segment and the back-inserting depth parameters of the vibroflot 6;
the verticality is an important control parameter in the encryption process of the vibroflotation device 6, and has an important influence on the pile forming form of the gravel pile. In general construction, the vibroflotation device 6 is arranged in a pile body in the encryption process, the difficulty of directly measuring the verticality is high, and the verticality of the vibroflotation device 6 can be indirectly judged by monitoring the inclination of the guide rod 4 arranged on the upper part of the vibroflotation device 6. Because the length of the guide rod 4 depends on the depth of the vibroflotation pile, the verticality of the vibroflotation device 6 in the encryption process is closely related to the depth and diameter of the pile;
in order to avoid the inclination of the pile body, the encryption process should ensure that the vibroflot 6 is vertically downward as much as possible, and the inclination of the guide rod 4 should be determined by a field pile test according to the designed pile depth.
The depth refers to the depth position in the pile body of the vibroflotation device 6 in the encryption process, and is one of important monitoring indexes of the vibroflotation device 6 in the encryption process. The depth position of the vibroflotation device 6 in the pile encryption process is monitored in real time, and whether key construction indexes such as vibroflotation encryption state, filler amount and pile body form are in a normal operation interval or not is judged;
the depth position of the vibroflotation device 6 can be monitored and displayed in real time through the lifting variable quantity of the lifting rope of the vibroflotation device 6.
The descending speed of the vibroflot 6 during encryption refers to the descending speed of the vibroflot 6 during encryption. When a continuous filling method is adopted, after backfill is poured into a pile, most of the backfill is loosely accumulated at the bottom of the pile because the vibroflot 6 and the guide rod 4 do not lift out a pile hole, and part of the backfill is scattered between the vibroflot 6 or the guide rod 4 and the pile wall, so that the descending speed of the vibroflot 6 is reasonably controlled, the backfill which does not fall into the bottom of the pile can fall into the bottom of the pile through excitation by means of the vibration of the vibroflot 6, and meanwhile, the uniform descending in the encryption process is beneficial to uniform compaction and compaction of the backfill at the bottom of the pile. The vibroflotation descending speed is determined by combining a field pile test, is generally not more than 1m/min, and stops descending when the current intensity approaches the upper limit of a designed current threshold.
The encryption rising speed of the vibroflotation device 6 refers to the speed of upward pulling when the vibroflotation device 6 meets the requirement of the vibration retention time in the encryption process of the vibroflotation device 6;
the up-and-down pulling process is a common method for vibroflotation encryption, is beneficial to uniformly encrypting the pile wall, and suggests that the encryption rising speed and the encryption falling speed are kept consistent in order to ensure the uniformity and the quality of the pile body.
The length of the primary encryption segment refers to the length of the segment of the vibroflot 6 for compacting soil or filling and piling, and the length (depth) of finishing a continuous encryption process in the encryption process. Too large a length easily causes leakage vibration or unevenness and incompact, and too small a length reduces construction efficiency;
the parameter determination should be combined with pile diameter, backfill grading and vibroflot 6 power determination, and the length of the primary encrypted segment is not more than 0.5-1 m in general.
The back-cut encryption is a method for improving the encryption effect of the pile body based on long-term vibroflotation construction experience, and the back-cut depth is a main reference index of the back-cut encryption. After the first encryption lifting, the vibroflotation device 6 is inserted back for the second compaction, so that the compaction effect of the pile body is greatly improved;
the common back-insert process comprises the following steps: once encryption of 0.5m and back insertion of 0.4m are performed for twice encryption, or once downward encryption of 1m and back insertion of 0.7m are performed. The specific back inserting depth can be determined to be an optimal value through a field pile test;
s4, obtaining the encryption parameters and control indexes of the backfill according to a backfill control module, wherein the backfill control module mainly comprises control parameters of replacement rate, broken stone gradation, filler content and mud content;
the replacement rate is also called area replacement rate, and refers to the ratio of the area of the reinforcement in the composite foundation to the area of the control range thereof according to the existing standard. The encryption effect of the pile body can be detected to a certain extent by the replacement rate data, and the poor compaction effect of vibroflotation or the insufficient compactness of the pile body is indicated by the low replacement rate, and the low replacement rate is uneconomical;
the rate of displacement is typically set in conjunction with formation conditions and design loads.
The crushed stone grading is the distribution condition of the grain diameters of all levels of crushed stone. The backfill material of the vibroflotation pile generally adopts the gravels, and the particle size grading of the gravels is scientific, thereby being beneficial to improving the compactness of the pile body and reducing the work efficiency of the encryption construction;
the vibroflotation gravel pile is suitable for continuous grading, and the optimal backfill particle size grading proportion data can be determined through a pile test.
The filling amount refers to the amount of broken stones filled into the pile body in the encryption process, the data is closely related to the replacement rate, real-time and accurate measurement of the filling amount data has important reference for analyzing the encryption quality, the filling amount control range can set a threshold value according to the recommended length value of each linear meter designed for the pile body, and in addition, reasonable control of the filling amount is beneficial to reducing the material cost.
The mud content is one of the important parameters for controlling the quality of the backfill crushed stone 7, the final compaction quality of the pile body is determined by the self quality of the backfill crushed stone 7, and the mud content of the graded crushed stone 10 serving as a backfill material is controlled below 5 percent in general;
s5, carrying out whole-process real-time monitoring and feedback according to the platform, acquiring regular working condition timing inspection and abnormal working condition manual handling related judgment, wherein in the step of carrying out whole-process real-time monitoring and feedback by the platform, the regular working condition timing inspection passes through a pile test to determine the power and the stratum conditions of the vibroflot 6, the inspection comprises manual timing field inspection, unmanned aerial vehicle video timing inspection and control system timing automatic inspection, the abnormal working condition manual handling adopts a method combining automatic handling and manual intervention handling to handle the problems, and the normal working condition state is recovered after the handling;
the regular inspection time setting under the normal working condition is determined by a pile test by combining the power of the vibroflot 6 and the stratum condition. The inspection can comprise manual timing field inspection, unmanned aerial vehicle video timing inspection, timing automatic inspection of a control system and the like.
The problem is treated by adopting a method combining automatic treatment and manual (expert) intervention treatment under the abnormal working condition, and the normal working condition state is recovered after the treatment is finished;
(1) system for automatically judging abnormal working condition
During encryption construction, when key parameters in each control module exceed threshold setting, the system automatically judges that the abnormal working condition state is entered, and automatically disposes according to an abnormal working condition database which is set in advance.
(2) Manually determining abnormal operating conditions
Under special conditions of finding problems in routing inspection, needing manual instruction change, meeting emergency shutdown, exceeding an abnormal working condition database and the like, the manual instruction is actively converted into an abnormal working condition, and manual (expert) intervention treatment is adopted. (ii) a
And S6, realizing intelligent control of the vibroflotation pile encryption quality according to the working parameters of the vibroflotation device 6 and the encryption parameters and control indexes of the backfill material.
