In recent years, China has built and will build a batch of 200m or even 300m high earth-rock dams. The gravel soil material has the advantages of good compaction performance, high shear strength, large filling density, rich storage capacity and the like, and is widely used as an anti-seepage material for a core wall area of a high earth-rock dam, such as foreign barrages (taggestein, 335m), nuilex (taggestein, 300m) and the like, domestic two estuaries (295m), double estuaries (314m), American (315m), long river dam (240m), glutinous ferry bundle (263m), waterfall ditch (186m) and the like.
Along with the continuous increase of the height of the dam, the dam body material is subjected to complex occurrence environment effects such as high stress, high osmotic pressure and the like, the gravel soil material in the core wall area of the dam needs to meet the requirements in various methods such as bearing capacity, seepage-proofing performance, shearing resistance and the like, and plays a vital role in the structural stability and seepage-proofing safety of the dam. According to related test requirements and geotechnical test regulations, the control requirements of an engineering site on a gravel-mixed soil material source are mainly embodied in the aspects of particle size distribution, water content and the like, such as the gravel soil material requirement P of a hydropower station with two river mouths5Content (gravel particle diameter)>5mm particle content) is strictly controlled within the range of 30-50 percent, and the water content is strictly controlledMade at Wop-1.5％≤W≤Wop+2.5％(WopOptimal moisture content). When the natural gravel soil material cannot meet the requirements, the gravel material and the soil material need to be blended and modified according to a certain proportion through a blending machine so as to meet the filling technical requirements.
The blending of the gravel soil materials is mainly carried out through a blending machine, in order to accurately monitor the blending times of the gravel soil materials and reduce the interference of human factors, researchers find out an automatic information acquisition device (patent number: CN106774097A) for the blending process of the gravel soil materials, and realize the real-time automatic acquisition of the information of the blending process of the gravel soil materials. The device can automatically identify the blending action of the large arm and the small arm of the machine, transmits action and position information to a rear data center in real time through the wireless transmission module, and obtains the blending frequency of the gravel soil materials through calculation and analysis. However, the invention is primarily directed to monitoring of a construction process in which the gravel is blended in situ. For more complex construction schemes, such as a large circulation blending construction process, i.e., gravel and soil materials are more uniformly mixed and easier to construct by large circulation back-blending, a new calculation scheme needs to be developed.

A monitoring and analyzing method for a large-circulation blending process of gravel soil materials is shown in figure 1 and comprises three parts of data acquisition of the blending process, data analysis of the blending process and feedback control of blending quality.
(one) blending Process data acquisition
The information automatic acquisition device for the gravel-doped soil material blending process is adopted to acquire blending process data in real time, all-weather, high-precision and full-automatic manner. The automatic information acquisition device for the gravel-doped soil material blending process mainly comprises the automatic acquisition of the mechanical dynamic position information, the positions of the large arm and the small arm of the blending construction machine, the course angle and other operation state information, and transmits data to the master control center server through the wireless communication radio station. The automatic information acquisition device for the gravel-doped soil material blending process comprises a main GPS satellite positioning module, an auxiliary GPS satellite positioning module, a wireless communication radio station, an RTK differential radio station module and a mechanical forearm operation monitoring module 5; the antenna 1 of the main GPS satellite positioning module is arranged at the top of the doped mechanical cab; the antenna 4 of the auxiliary GPS satellite positioning module is arranged on a platform at a connecting node between a large blending mechanical arm and a small blending mechanical arm, and meanwhile, the antenna 4 of the auxiliary GPS satellite positioning module and the antenna 1 of the main GPS satellite positioning module are kept on a straight line parallel to the direction of a vehicle body of the blending mechanical module as much as possible; an antenna 2 of a sending module of the wireless communication radio station is arranged at the top of the doped mechanical cab; an antenna 3 of the RTK differential radio module is arranged at the top of a doped mechanical cab; the mechanical forearm operation monitoring module 5 is installed on a plane on the back surface of the blended mechanical forearm, and the mechanical forearm operation monitoring module 5 adopts an inclination angle sensor. All the monitoring modules are arranged in the equipment integration case and are arranged in the cockpit, and the antenna and the sensor equipment of each module are arranged on the top of the cockpit and each key node. As shown in fig. 2, the mechanical dynamic position information of the automatic blending process information acquisition device is mainly obtained by positioning the position of the antenna 1 of the main GPS satellite positioning module installed at the top of the cockpit, and is differentiated by the RTK differential radio module to improve the positioning accuracy. The antenna 4 of the auxiliary GPS satellite positioning module is arranged on a platform at the middle connecting node of the large arm and the small arm of the blending machine, and is kept on a straight line parallel to the direction of the vehicle body as much as possible with the antenna 1 of the main GPS satellite positioning module. The mechanical forearm operation state monitoring module adopts an inclination angle sensor, is arranged on a plane on the back of the forearm for preventing the mechanical forearm operation state monitoring module from being accidentally damaged, and ensures that the mechanical forearm operation state monitoring module is horizontal or vertical to the axis of the forearm as far as possible according to the equipment type of the inclination angle sensor.
According to the relevant data collected by the device for automatically collecting the gravel-doped soil material blending process information, the dynamic position information of the blending machinery, the construction action of the blending process, the blending shoveling position and the blending throwing position can be judged, and the following description will be specifically provided with reference to fig. 2.
First, the main GPS satellite positioning module obtains the position information a (a) of the space point a (the space point a is the position of the antenna 1 of the main GPS satellite positioning module)x(t),ay(t),azAnd (t)), wherein t is a time item, and dynamic position information of the blending machine can be obtained through the position information. Meanwhile, the auxiliary GPS satellite positioning module can obtain the position information B (B) of the space point B (the space point B is the position of the antenna 4 of the auxiliary GPS satellite positioning module)x(t),by(t),bzAnd (t)), therefore, the course angle of the operation mechanical arm of the blending machine can be calculated in real time through the position information of the space point A and the space point B, and when a certain fixed moment is selected, the process of determining the construction action, the blending shoveling position and the blending throwing position in the blending process is converted into a plane problem from a space problem.
Next, as shown in fig. 2, taking the position as an example, a space point C is a connection point position of the bucket and the boom of the blending machine, and a space point D is a connection node of the boom of the blending machine and the boom of the blending machine. The position of the spatial point C can be determined by the following formula (which can be simplified to a planar problem in the x-z plane, considering some fixed time instant):
in the formula, cxThe position of the spatial point C in the x direction at a certain fixed time; c. CzThe position of the spatial point C in the z direction at a certain fixed moment; bxThe position of the spatial point B in the x direction at a certain fixed time; bzIs a certain oneThe position of the space point B in the z direction at a fixed time; m is1Is the distance between the space point B and the space point D in the x direction; m is2Is the distance between the space point C and the space point D in the x direction; n is1Is the distance between spatial point B and spatial point D in the z direction; n is2Is the distance in the z direction between spatial point C and spatial point D; wherein m is1，m2，n1，n2Obtained from equation (2):
in the formula, theta is an included angle between the doped mechanical forearm and the horizontal plane and can be obtained from a pitch angle of the tilt angle sensor; alpha is the included angle between the straight line of the space point B and the space point D and the horizontal plane, and the length between the space point B and the space point D is the same as the length between the space point B and the space point D
The numerical value is small, so that the alpha value is approximately 45 degrees in the research, and the requirement of on-site monitoring precision can be met.
Finally, the spatial position of the bucket can be obtained by considering the length and width information of the bucket according to the position information of the connecting point C of the bucket and the blending mechanical arm.
(II) blending Process data analysis
The method mainly comprises logic judgment of a large-cycle blending process, real-time analysis of automatically acquired data and visual expression of a real-time blending process.
Logical judgment of large-cycle blending process
And the logic judgment of the large-cycle blending process needs to summarize the logic rule of the large-cycle blending construction method. The mixing adopts a 'flat-laying vertical mining method' for construction, namely, the gravel material and the stone material are subjected to interbedding material laying according to a certain thickness proportion before construction, and then the vertical mining circular mixing is carried out by a mixing machine by adopting a large-circulation construction method.
