Description

Technical Field

[0001] The present invention relates to the field of sensor monitoring and mechanical excavation construction, and in particular to a sensor installation device and a method for using the sensor that can reduce the environmental disturbance caused by excessive soil excavation within the sensor installation range and the influence on monitoring data. Background Art

[0002] In recent years, with the vigorous promotion and development of refined civil engineering construction, the characteristics and development trends of geotechnical environment in various stages of engineering construction have also been widely concerned. How to efficiently, reasonably and standardizedly realize the observation and data collection of deep underground environment has become a difficult problem and a technical problem that needs to be improved urgently. There are many types of sensors currently used for deep underground environmental performance monitoring, such as soil pressure monitoring sensors, pore water pressure monitoring sensors, water content monitoring sensors, displacement monitoring sensors, etc. Although different sensors have different shapes and working principles, the methods of burial and data collection have certain similarities.

[0003] At present, in terms of the existing sensor embedding and installation methods, the commonly used method is to directly excavate to the specified depth, then lower the sensor and directly backfill, and the excavation-embedding-filling of the sensor cannot be completed in a complete set. For example, Chen Yong et al. from the Three Gorges University’s invention patent "A sensor embedding device and embedding method thereof" (CN111622198A), Tang Yiqun et al. from Tongji University’s invention patent "A deep soil multiple sensor embedding device and embedding method thereof" (CN109056687A), and An Xiaoyu et al. from the Tianjin Water Transport Engineering Science Research Institute of the Ministry of Transport’s invention patent "Device and method for precise positioning and rapid embedding of micro sensors" (CN109142006A). The above sensor embedding equipment and methods cannot complete the digging-burying-filling work of sensors with a complete set of equipment. It is difficult to achieve visual and controllable mechanized operation when installing deep layers and multiple sets of sensors. Directly lowering and backfilling the soil in the excavated hole will cause excessive disturbance to the soil environment around the sensor, changing the properties and conditions of the original monitoring environment, resulting in inaccurate monitoring data results, which is difficult to meet the needs of geotechnical monitoring. Summary of the invention

[0004] In order to solve the problem that the existing technology cannot complete the digging-burying-filling work with a set of equipment, the present invention provides a sensor installation device and a method for using the digging-burying-filling integration. The device and the method for using the device can realize the one-time digging-burying-filling work of sensors at different depths underground with minimal disturbance to the rock and soil environment around the sensor under visual and controllable semi-automatic operation, reduce the cost of manpower excavation, and realize the burying and backfilling of sensors in a standardized and systematic manner. At the same time, the method of burying the sensor in a small hole excavated in the side wall can reduce the amount of excavation and backfilling of soil around the sensor, thereby reducing the changes in the monitoring environment caused by post-construction settlement and insufficient backfill compaction, and the resulting inaccurate monitoring data.

[0047] The present invention mainly solves the problem of inaccurate monitoring data caused by factors such as large disturbance of geotechnical environment, insufficient backfill compaction, post-construction settlement and soil loss caused by the traditional installation method of direct excavation and landfilling during the installation of sensors required for underground geotechnical environment monitoring, as well as the problem that the underground sensor excavation-burying-filling process cannot be completed in a good system. It mainly uses semi-automatic, controllable and visible mechanical equipment to excavate a small pre-buried hole of the same size as the sensor towards the intact soil side wall after the main hole is excavated, and then the sensor is placed and mechanized backfilling is carried out to reduce the disturbance of the soil environment in the sensor contact interface, and the whole process is mechanized, controllable and visible, which improves the standardization of sensor burial work and the quality and accuracy of monitoring data.

[0048] To make the objects, advantages and features of the present invention more apparent, the following Figure 1 -5 and the specific implementation mode (longitudinal excavation) further describe the present invention in detail, and the horizontal excavation mode can be achieved by making corresponding adjustments to the longitudinal excavation mode.

[0049] The integrated digging-burying-filling sensor installation device consists of a chain-guide rail lifting system, an excavation main drill bit, a first transparent surrounding barrel, a second transparent surrounding barrel, a detailed drilling and digging structure in the hole, a detailed backfilling structure in the hole, a main hole backfilling structure and an integrated control host system.

[0050] The integrated digging-burying-filling sensor installation device can semi-automatically bury and backfill sensors deep in the vertical direction with reduced disturbance, and can also bury and backfill sensors horizontally or at a certain angle to realize the collection of different types of data. The integrated digging-burying-filling equipment controlled by the integrated control host system can bury and backfill sensors deep in the underground soil under the condition that the thrust and drilling speed are controllable and visible.

[0051] like Figure 1 The spliced ​​frame is a cubic hollow steel frame structure, a groove of a certain depth is provided on the top edge of the frame, and a protrusion matching it is provided on the bottom edge. Two adjacent frame structures are spliced ​​and reinforced by the groove and protrusion structure with bolts and nuts, thereby forming a main frame support structure of the sensor installation device of any height. In addition, a pair of side surfaces of the frame structure are provided with lateral guide rail structures to provide guide support for the drilling of the main drill bit for excavation.

[0052] The main excavation drill bit is composed of a drill rod and a motor, fixed on a replaceable top plate with a central opening, and moves along the side rails of the chain-guide rail lifting system driven by the drilling power.

[0053] As shown in Figures 2 (a)-2 (c), the chain-guide rail lifting system: the main frame support structure is assembled from a splicable frame. The support mechanism can not only complete the vertical excavation work, but also can be adjusted to any angle in the horizontal direction for excavation. The support structure and the pulleys, motors, side rails, replaceable top plates and chains on both sides of the bottom constitute a lifting and moving system. The middle opening of the replaceable top plate, the replaceable fixed excavation main drill bit, the detailed drilling and excavation structure in the hole, the detailed backfilling structure in the hole, the first transparent enclosure barrel, the second transparent enclosure barrel, the main hole backfilling structure, and move along the side rail direction driven by the chain-guide rail lifting system and the hydraulic power system. The bottom plate of the chain-guide rail lifting system is provided with a displacement sensor and a level meter to monitor the horizontal state of the system and the depth of drilling and placement. It should be pointed out that Figure 2 (c) shows the state of the installation device when it is excavating horizontally. Those skilled in the art can read the longitudinal excavation implementation method in this specification and make corresponding adjustments to achieve horizontal excavation.

[0054] As shown in Figures 3 (a) and 3 (b), the first transparent barrel is fixed at the top to a replaceable top plate with a hole in the middle of the chain-guide lifting system, and the lower part extends into the excavated main hole. The side walls of the barrel are penetrated with pairs of holes at intervals according to the installation positions of the sensors. A pinhole camera is provided above the hole on one side to observe the excavation of the sensor embedding hole. A grooved sharp-angle structure is fixed to the lower side of the first transparent barrel by a bolt structure. The protruding direction of the sharp corner is on the same vertical line as the hole on the side where the pinhole camera is provided. When the first transparent barrel is lowered, the grooved sharp-angle structure can carve a vertical groove on the excavated main hole, into which the sensor connecting line can be placed.

[0055] As shown in Figures 3(c) and 3(d), the second transparent barrel is fixed at the top to a replaceable top plate with a hole in the middle of the chain-guide lifting system, and the lower part extends into the excavated main hole. The side wall of the barrel is provided with a vertical slit for the wire to enter and exit. The bottom of the barrel is a sealed inverted T-shaped hole structure, in which a detailed backfill structure is placed for the placement and backfilling of sensors, and it is lifted step by step from bottom to top to complete the buried work of sensors at different depths.

[0056] As shown in Figures 4 (a)-4 (c), the detailed drilling and excavation structure in the hole is designed with a corresponding number and spacing of fishbone-shaped internal hanging support structures according to the number and spacing of buried sensors, which are suspended in the first transparent barrel. At the designed sensor burying location, corresponding to the through holes of the first transparent barrel, lateral extension ends are provided. A retractable drill bit is provided on one side of the sensor burying location of each pair of lateral extension ends, and a first jack (small jack) is provided on the other side. When working, the retractable drill bit and the small jack are extended from the through hole at the same time. The retractable drill bit excavates the sensor burying hole at the designed position, and the small jack contacts the opposite side soil wall to provide reaction support force.

[0057] As shown in Figures 4 (c)-4 (k), the detailed backfilling structure in the hole is composed of an L-shaped backfilling bin, a second jack, and a third jack, and is placed at the bottom of the second transparent enclosure. After being lowered to the designated position by the chain-guide lifting system, the second jack first pushes the L-shaped backfilling bin into the excavated sensor burying hole, and then the third jack pushes the sensor lowered into the bin into the burying hole, and then the third jack is retracted and put into the discharge pipe, and the backfill soil is poured into the bin by the discharge pipe, and the backfill soil is pushed into the burying hole by the third jack and compacted by static pressure until the burying hole is backfilled. Finally, the discharge pipe is retracted, and the second jack drives the L-shaped backfilling bin to retract from the vicinity of the burying hole into the second transparent enclosure. The detailed backfilling in a hole is completed, and the lifting system lifts the second transparent enclosure to the upper burying hole, and repeats the above operation. This operation can realize the burying of soil backfilling, steel needle insertion and cement sealing sensors.

[0058] As shown in Figures 5(a) and 5(b), the main hole backfill structure is composed of a top hydraulic device and a compaction hammer. When all sensor holes are buried and backfilled, the main hole backfill structure is replaced and installed in the middle of the replaceable top plate. Backfill soil is lowered from the hole opening. The hydraulic device drives the compaction hammer to compact the backfill soil poured into the main hole layer by layer until the compaction requirements are met and the main hole backfill is completed. Then, the backfill soil is lifted up to the outside of the hole opening layer by layer.

[0059] The integrated control host system is composed of a computer control system, connecting wires and cameras. The connecting wires connect the chain-guide lifting system, the main excavation drill bit, the detailed drilling and excavation structure in the hole, the detailed backfill structure in the hole, and the main hole backfill structure to the computer control system, and are connected to the cameras installed on the first and second transparent barrels to control the operation and stop of each component, thereby realizing visible and controllable underground sensor burial work.

[0060] The operation and application of the present invention in the vertical direction specifically includes the following steps:

[0061] Step 1: Push the chain-guide lifting system to the sensor embedding point, assemble the splicable frame body 1 to a sufficient height according to the maximum design embedding depth of the sensor, fix the bottom and adjust the level, debug the displacement sensor 11 and return it to zero, install the main drill rod 8 together with the main drill motor 7 into the hole in the middle of the replaceable top plate 6 with a hole in the middle, and connect the connecting wire 17 to the junction box of the integrated control host system;

[0062] Step 2: The computer control system 18 of the integrated control host system starts the equipment, so that the main drill rod 8 drills vertically downward along the side rail 9, and the displacement sensor 11 monitors the depth of the drill bit moving downward until the preset drilling depth is reached, the rotation drilling of the main drill rod 8 is stopped, and the chain-guide lifting system is used to lift it outside the excavation main hole, and the main drill rod 8 in the middle of the replaceable top plate is taken out together with the main drill motor 7;

[0063] Step 3: Place the first transparent enclosure barrel 23 in the middle of the replaceable top plate 6 with a hole in the middle, hang the inner hanging support structure 27 of the detailed drilling structure in the hole prefabricated according to the number of sensors, the interval and the depth of the sensors in the first transparent enclosure barrel 23, start the chain-guide rail lifting system to lower the two to the preset embedding position, control the retractable drill bit 28 and the small jack 29 to extend from the through hole of the first transparent enclosure barrel 23 at the same time, and the retractable drill bit 28 digs the sensor pre-buried hole 34 at the designed position, and the first jack 29 contacts the opposite side soil wall to provide a reaction support force until the drilling depth of the retractable drill bit 28 meets the requirements, then stop drilling, and retract the retractable drill bit 28 and the first jack 29 to the first transparent enclosure barrel 23, and lift them out of the hole by the chain-guide rail lifting system, and take them out from the middle of the replaceable top plate 6 with a hole in the middle;

[0064] Step 4: Place the second transparent barrel 30 with the detailed backfill structure in the hole on the bottom in the middle of the replaceable top plate 6 with a hole in the middle, and lower it to the deepest position of the sensor pre-buried hole 34 by the chain-guide lifting system. First, the second jack 36 pushes the L-shaped backfill bin 35 into the excavated sensor pre-buried hole 34, and then the third jack 37 pushes the sensor 38 lowered into the bin into the sensor pre-buried hole 34, then the third jack 37 is retracted and put into the discharge pipe 39, and the backfill soil is poured into the L-shaped backfill bin 35 by the discharge pipe 39, and the second jack 36 is used to The backfill soil is pushed into the sensor pre-buried hole 34 and compacted by static pressure until the sensor pre-buried hole 34 is backfilled. Finally, the feed pipe 39 is retracted, and the second jack 36 drives the L-shaped backfill material bin 35 to retract from the vicinity of the sensor pre-buried hole 34 into the second transparent enclosure 30. After the backfilling of the details in one hole is completed, the chain-guide lifting system is used to lift the second transparent enclosure 30 to the upper buried hole. The above operation is repeated until all underground sensors are installed. The chain-guide lifting system is used to lift the second transparent enclosure 30 out of the hole and take it out from the middle of the replaceable top plate 6 with a hole in the middle.

[0065] Step 5: Place the main hole backfill structure in the middle of the replaceable top plate, pour the backfill soil into the excavated main hole in small amounts and multiple times, lower the main hole backfill structure by the chain-guide rail lifting system until it is suitable, start the top hydraulic device 41 to drive the compaction hammer 40 to compact the backfill soil in the hole, and after compaction to the standard requirements, lift the main hole backfill structure upward, pour a small amount of backfill soil again for compaction, and repeat this operation until the excavated main hole is backfilled. The main hole backfill structure is lifted above the ground surface by the chain-guide rail lifting system, and the digging, burying and filling work of the underground sensor is completed;

[0066] Step 6: Arrange and recover all lines, excavation equipment and integrated control host system, and operate the next sensor embedding point.
