[0036] In order to enable the present invention to achieve the intended purpose and function more effectively, the structure, features and specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. The detailed description is as follows:

[0037] like Figure 1 and 2 As shown, a multifunctional and portable field survey device includes a polygonal platform 1 and auxiliary equipment and a grouting system 6 arranged on the platform, wherein the auxiliary equipment includes a drilling machine 2, a static probe-cross shear dual-purpose instrument 3 and a sampler 4. The platform 1 is used as a carrier, and 4 sets of tire structures are arranged at the bottom for movement.

[0038] Combination Figure 3 and Figure 4 As shown, the edge of the platform part 11 of the platform 1 is provided with twelve inwardly recessed notches, and areas for installing auxiliary equipment are formed on the platform 1 corresponding to the notches, namely, four drilling rig installation areas 12, 13, 14, and 15 located at the four corners of the platform; six static probe-cross shear dual-purpose instrument installation areas 16, 17, 18, 19, 110, and 111 on the side and both ends of the platform and two sampler installation areas 112 and 113 in the middle of the side of the platform; a layout area 114 for a grouting system 6 is also provided in the middle of the platform 11, and a slurry bucket of the grouting system 6 is arranged on this area, and an electric box layout area 115 and an ultrasonic instrument installation area 116 are provided on the top surface of the slurry bucket.

[0039] The platform 11 can be regarded as a structure obtained by cutting off 12 small rectangular blocks along the four sides of a large rectangular block, and the remaining parts are solid. Metal materials such as alloys can be selected and the structure is axially symmetrical. The space vacated after cutting off the small rectangular blocks is used for the drilling tools, drilling rigs and other components of the auxiliary equipment to pass through the polygonal platform and enter the soil layer. At the same time, it can ensure that the auxiliary equipment is completely within the range of the platform, which can effectively prevent the platform 1 from colliding with the auxiliary equipment during movement.

[0040] A drilling rig 2 is fixedly installed in each of the four drilling rig installation areas; the six static probe-cross shear dual-purpose instrument installation areas are divided into two symmetrical groups, each group includes static probe-cross shear dual-purpose instrument installation areas on two platform sides and one end, and each group is only equipped with one static probe-cross shear dual-purpose instrument 3; a sampler 4 is fixedly installed in each of the two sampler installation areas; an electric box 7 and an ultrasonic detector 5 are installed in the electric box layout area 115 and the ultrasonic instrument installation area 116 respectively.

[0041] There are also two groups of slide rail structures 117 on the top surface of the platform part 11 of the platform 11, which correspond to two groups of static probe-cross shear dual-purpose instrument installation areas respectively. The slide rail structure 117 connects the three static probe-cross shear dual-purpose instrument installation areas of each group for use when the static probe-cross shear dual-purpose instrument 3 is moved. A pulley that cooperates with the slide rail structure 117 is provided at the bottom of the static probe-cross shear dual-purpose instrument 3.

[0042] When this embodiment is in use, the drills 2 at the four corners of the platform 1 penetrate the platform 1 from the corresponding notches and drill into the soil layer to form fixed legs; the static penetration tester 3 moves to the installation areas on the side and top and penetrates the platform from the corresponding notches and drills into the soil layer to perform a cross shear test and a static penetration test, thereby performing different tests on the soil layers at different positions, increasing the flexibility of the device and being able to move the equipment smoothly and effectively; the sampler 4 penetrates the platform from the corresponding notches and drills into the soil layer to take samples; after the above tests are completed, the grouting system is used to inject grout into the holes generated by the auxiliary equipment to restore the flatness and strength of the soil layer.

[0043] Embodiment 2 This embodiment is further designed based on Embodiment 1, specifically: Figure 3 and Figure 4 As shown, two circular through holes 118 are arranged at corresponding positions of the static probe-cross shear dual-purpose instrument installation areas 16, 17, 18, 19, 110, and 111, so as to facilitate the use of screws 39 to fix the device after the static probe-cross shear dual-purpose instrument 3 is moved to the installation area.

[0044] At the same time, a circular through hole 119 is drilled on both sides of the middle of the slide rail structure 117, so that the static probe-cross shear dual-purpose instrument 3 can be fixed to the middle of the platform part 11 by screws 39 when it is not in use.

[0045] A through cable hole 121 is also drilled next to the paddle bucket arrangement area 114 of the platform portion 11 , and a pipeline hole 122 is also drilled at the center of the paddle bucket arrangement area 114 .

[0046] The grouting system 6 includes a slurry bucket 61, a grouting main pipe 63 connected to the slurry bucket 61, and a plurality of grouting branches 64 connected to the grouting main pipe 63; the slurry bucket 61 is arranged in the slurry bucket arrangement area 114 in the middle of the platform part 11, and is used to place slurry, and a grouting port is reserved on the top surface, and the rest of the part is closed, and a grouting main pipe 63 extends downward from the bottom surface, which extends to the bottom of the platform through the pipe hole 122 reserved in the middle of the platform part 11, and the grouting main pipe 63 extends out of the bottom of the platform part 11 and then extends to the installation area of ​​the auxiliary equipment at each notch of the platform. Metal lifting ears 130 are welded at the corresponding positions where pipes need to be laid, and the extended branch pipes 64 are fixed to the bottom of the platform part 11 with a sufficient number of lifting ears 130; a high-pressure pump 62 is arranged on the grouting main pipe 63, and the high-pressure pump 62 is connected to the electric box 7 through the cable hole 121 using a cable 67; a valve 65 is arranged at the grouting branch pipe 63 where it is about to extend out of the notch; several grouting branch pipes 63 are continuous steel pipes inside the valve, and are connected to a detachable and bendable hose 66 extending out of the valve. When the hose 66 is not needed temporarily, the hose 66 is bent and placed on the hook 129 set on the side of the corresponding notch.

[0047] The platform portion 11 is drilled with four non-through cylindrical holes 120 from the bottom upwards for mounting the tire structure.

[0048] Combination Figure 5 As shown, the left side is a three-dimensional schematic diagram of the tire structure, the upper middle part is a main view of the tire structure, the lower part is a structural diagram after the wheel eyebrow is removed, the upper right part is a left view of the tire structure, and the lower part is a schematic diagram of the support column 125 and the horizontal axis 124; the tire structure includes a connecting structure and a rubber tire, the connecting structure includes a supporting column 125 for connecting to the cylindrical hole 120, and a horizontal plate 126 connected to the supporting column 125, 4 small connecting columns 127 and a wheel eyebrow 128; the rubber tire is composed of a carcass 123 and a horizontal axis 124 connected, and two carcasses 123 and one horizontal axis 124 constitute a set of rubber tires.

[0049] The support column 125 is connected to the transverse axis 124 of the rubber tire. The transverse plate 126 is fixed on the support column 125 and is connected to the wheel eyebrow 128 by four small connecting columns 127, which can be welded.

[0050] During installation, the support column 125 is pushed into the four non-penetrating cylindrical holes 120 at the bottom of the platform portion 11 until the cross plate 126 abuts against the bottom of the platform portion 11, and then the cross plate 126 is welded to the bottom of the platform portion 11. The length of the support column 1254 above the cross plate 126 should match the height of the non-penetrating cylindrical holes 120 drilled upward from the bottom of the platform portion 11.

[0051] Combination Figure 6 As shown, the drilling rig 2 includes a drilling rig support 25 fixed on the platform 1, a drilling rig track 22 arranged on the drilling rig support 25, a drilling rig rack 23 fixed on the drilling rig track 22, and a drilling rig mainframe 21 slidably connected to the drilling rig track 22, the drilling rig mainframe 21 is provided with a gear meshing with the drilling rig rack 23 and a motor driving the drilling rig gear, and a drill rod 24 is provided at the end of the drilling rig mainframe.

[0052] The drilling rig 2 needs the electric box 7 as a power supply when in use, and is connected by a cable 210. The drilling rig bracket 25 is fixed on the drilling rig installation areas 12, 13, 14, 15 of the polygonal platform by welding.

[0053] When in use, the drill mainframe 21 drives the drill rod 24 to rotate and also drives the gear to roll on the drill rack 23 , thereby enabling the drill mainframe 21 to drill downwards or be pulled out upwards along the drill track 22 .

[0054] Combination Figure 7 As shown, a small basket 28 is welded on the drilling rig track 22, and a digital frequency meter 29 is arranged inside the small basket 28. The digital frequency meter 29 is connected to the electric box 7 by a cable 211, and the cable 27 and cables 210 and 211 need to have sufficient length.

[0055] The drill bit of the drill rod 24 is a spiral structure, the end of which is a conical structure, and a soil pressure sensor 26 is installed near the conical structure. Figure 8 As shown, the soil pressure sensor 26 is a regular hexagon formed by welding six sensors with rectangular planes. The empty parts at the joints are filled with the same material as the outer shell of the pressure sensor 26. It can measure the soil pressure in six planes and is fixed to the upper structure and lower conical structure of the drill pipe as a whole by welding.

[0056] The interior of the earth pressure sensor 26 is directly connected to the cable 27. A space is left inside the upper structure of the drill rod 24 for the cable 27 to pass through. The cable 27 passes through the interior of the drill rod 24 and is connected to the digital display frequency meter 29 after being exposed from the circular hole at the top of the drill rod 24. However, since the sensor 26 and the circular hole at the top of the drill rod 24 rotate with the drill rod 24, the cable 27 needs to have a sufficient surplus length. The extra length can be enough to wrap around the drill rod during the rotation of the drill rod, so as to avoid pulling the cable 27 during the drilling process of the drill rod.

[0057] When the drill rod 24 enters the soil layer, the surrounding soil layer squeezes the soil pressure sensor 26, and then the soil pressure sensor 26 can transmit the signal to the digital frequency meter 29 through the cable 27, so as to measure the soil pressure index of the soil layer.

[0058] After the drill rod 24 of the drilling rig 2 is drilled into the soil layer, it can not only complete the corresponding data collection but also serve as a fixed leg of the entire polygonal platform 1, ensuring that the polygonal platform 1 can remain stable during geological exploration tests.

[0059] Combination Fig. 9 and Fig.10 As shown, this embodiment adopts the existing static probe-cross shear dual-purpose instrument 3, and the structure is briefly explained without further elaboration. The static probe-cross shear dual-purpose instrument 3 is mainly composed of a main unit 31, a cross plate torque box device 32, a probe rod 33, a cross shear plate probe 34, a pulley 35, a conical static probe probe 36, a cable 37, a reader 38 and a screw 39.

[0060] The two static probe-cross shear dual-purpose instruments 3 are fixed to the middle of the left and right sides of the platform part 11 with screws when not in use, and a pulley 35 is provided at the bottom. When in use, the screws 39 can be removed, and then the instruments can be moved along the slide rail structure 117 on the top surface of the platform part 11.

[0061] Taking the static probe-cross shear dual-purpose instrument 3 on the left as an example, when in use, unscrew the screw 39. If a cross shear test is to be performed, the probe-cross shear dual-purpose instrument 3 is moved along the slide rail structure 117 to the static probe-cross shear dual-purpose instrument installation areas 16 and 18 respectively, and the screws 39 are passed through the circular through holes 118 and then locked. The cross plate probe 34 is connected to the probe rod 33, and then the measuring instrument 38 is connected to the cable 37 at the head of the static probe-cross shear dual-purpose instrument to perform a cross shear test to obtain the required data; if a cone static penetration test is to be performed, the probe-cross shear dual-purpose instrument 3 is moved along the slide rail structure 117 to the area 110, and the screws 39 are passed through the circular through holes 118 and then locked. The cross plate probe 34 is replaced with a cone static probe probe 36, and then a static penetration test is performed to obtain the required data.

[0062] Combination Fig.11 As shown, the sampler 4 includes a sampling bracket 45 welded on the platform 1, a sampling track 42 arranged on the sampling bracket 45, a sampling rack 43 fixed on the sampling track 42 and a sampling main unit 41 slidably connected to the sampling track 42, the sampling main unit 41 is provided with a gear meshing with the sampling rack 43 and a motor driving the gear, a rotary joint 46 is provided at the end of the sampling main unit 41, a drill interface and an ultrasonic detection rod interface are provided on the rotary joint 46, and the drill interface and the ultrasonic detection rod interface are interchanged by rotating the rotary joint; the drill interface is detachably connected with an extension rod 47, and a cylindrical drill bit 44 is provided on the bottom end of the extension rod 47.

[0063] The sampling host 41 is connected to the electrical box 7 by a cable 48, which can drive the extension rod 47 and the cylindrical drill bit 44 to rotate while also driving the gear to roll on the sampling rack 43, so that the sampling host 41 can move downward or upward along the sampling track 42, thereby driving the extension rod 47 and the cylindrical drill bit 44 to drill downward or pull out upward.

[0064] In this embodiment, the cylindrical drill bit 44 is hollow, and the bottom is a wave-shaped structure. The barrel body has a detachable cover. When drilling out the soil layer, the soil sample can be left in the barrel body, and the soil sample can be obtained by removing the cover.

[0065] The rotary joint 46 at the end of the sampling main unit 41 can realize the interchange of the position of the joint connected to the extension rod 47 on the sampling main unit 41 and the joint connected to the ultrasonic detection rod after it rotates 180°. After sampling, the extension rod 47 and the cylindrical drill bit 44 are removed, and the rotary joint 46 is rotated to install the ultrasonic detection rod. This can ensure that the ultrasonic detection rod is exactly located at the hole formed by the cylindrical drill bit 44, which is convenient for continuing the ultrasonic detection test.

[0066] Combination Fig.12 and 13 As shown, the ultrasonic detector 5 includes an ultrasonic detection rod 51, an ultrasonic instrument 55 arranged on the platform 1, and a transmitting transducer 52 or a receiving transducer 53 arranged at the end of the ultrasonic detection rod 51. The ultrasonic instrument 55 is installed on the top surface of the paddle bucket 61, and is connected to the transmitting transducer 52 and the receiving transducer 53 by a cable 54. The ultrasonic detection rod 51 is detachably connected to the ultrasonic detection rod interface on the rotary joint 46. The ultrasonic instrument 55 uses the electric box 7 as a power source and is connected by a cable 56.

[0067] The end of the ultrasonic detection rod 51 is a cone structure, and a transmitting transducer 52 or a receiving transducer 53 is installed near the cone. A certain space is reserved in the ultrasonic detection rod 51 for the cable 54 to pass freely, and the cable 54 and the cable 56 must be of sufficient length.

[0068] When this embodiment is used, the transmitting transducer 52 and the receiving transducer 53 are respectively installed on the ultrasonic detection rods 51 on the two opposite samplers. Except for the position where they are connected to the soil layer, the rest of the surface is tightly connected to the inside of the ultrasonic detection rod 51. The remaining free surface is used to contact the soil layer to detect whether the soil layer between the two ultrasonic detection rods 51 is uniform.

[0069] When using the ultrasonic detector 5, please note that after the sampling is completed and the extension rod 47 and the cylindrical drill bit 44 are removed, the rotatable structure 46 must be rotated 180° before the ultrasonic detection rod 51 can be installed on the joint of the ultrasonic detection rod 51 set on the main unit 41 of the sampler 4. At this time, the ultrasonic detection rod 51 is at the position of the sampling hole. Note that when installing the ultrasonic detection rod 51, it is necessary to ensure that the free surfaces of the transmitting transducer 52 and the receiving transducer 53 are opposite to each other.

[0070] Combination Fig.14 As shown, a slot for placing an RFID electronic tag 8 is provided on the side of the platform 1, which can record multiple measured indicators in a timely manner through a reader / writer. The slot 81 of the RFID electronic tag 8 is a stepped groove chiseled in the side of the platform 1, and the RFID electronic tag body 83 is placed on the bottom layer, and a transparent plastic buckle 82 is installed, and a flip cover 84 is also provided.

[0071] The use sequence of the device can be roughly divided into the following steps: fixing the drill rig down to the drill, conducting a cross shear test, conducting a cone static penetration test, sampling, conducting an ultrasonic test, pulling out the drill rig, and filling the borehole. During use, the use order of fixing the drill rig down to the drill rig, pulling out the drill rig, and filling the borehole is fixed. At the same time, ultrasonic testing must be performed after sampling. In addition, the order of the remaining operation steps can be changed in sequence or performed simultaneously according to the actual situation. Specifically, the following steps are included:

[0072] A. This on-site survey device is moved to the survey area with the help of a tire structure.

[0073] B. Connect the cable 210 between the drilling rig 2 and the electrical box 7, the cable 48 between the sampler 4 and the electrical box 7, and the cable 211 between the digital frequency meter 29 and the electrical box 7.
