Description

Technical Field

[0001] The invention belongs to the technical field of earthwork construction, and in particular relates to a device for monitoring and checking hidden dangers in highway engineering construction. Background Art

[0002] During highway construction, especially during the dynamic compaction construction of collapsible loess roadbed, because the soil is composed of three parts: solid minerals, water and gas, solid minerals constitute the skeleton of the soil. There are a large number of pores between the skeletons, and there is water and air in the pores. When the initial moisture content of the foundation is high, as long as the number of tamping times is large, the moisture in the foundation cannot dissipate instantly, and the foundation can easily be compacted into "rubber soil", which needs to be re-dug and replaced with good soil, which will seriously delay the construction progress and increase the construction cost. Therefore, for dynamic compaction construction, excessive tamping is a construction hazard that needs to be monitored and investigated.

[0003] The existing patent with announcement number CN205100200U discloses an intelligent dynamic compaction construction monitoring system, including a microwave instrument and a data processing device connected to the microwave instrument, which can realize automatic detection and monitoring of the dynamic compaction construction process, including automatic detection and monitoring of hammer lifting height, effective compaction number, hammer drop distance, compaction degree and compaction level.

[0004] The prior art has the following problems:

[0005] Due to the lack of detection of soil foundation data, whether it is over-compacted can only be compared with theoretical calculated values. It is impossible to prevent the hidden dangers of local over-compacting, and there is a lack of objective monitoring and investigation of hidden dangers in the construction of collapsible loess roadbed. Summary of the invention

[0006] The invention provides a device for monitoring and checking hidden dangers in highway engineering construction, which can solve the technical problem in the prior art of lacking objective monitoring and checking of hidden dangers in the strong compaction construction of collapsible loess roadbed.

[0007] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0008] The present application provides a device for monitoring and checking hidden dangers in highway engineering construction, comprising a laser transmitter connected to the surface of a roadbed, a breaking cone, a pore water pressure gauge, a counterweight and an alarm module, wherein the breaking cone is used to be inserted into the roadbed during dynamic tamping construction, and the end of the breaking cone inserted into the roadbed is cone-shaped; the pore water pressure gauge is connected to the inner side of the breaking cone, and is used to monitor the pore water pressure flowing from the roadbed into the breaking cone; the counterweight is connected to the inner side of the breaking cone, and the counterweight makes the load on the roadbed below the breaking cone greater than the design load of the roadbed construction and less than the maximum load of the roadbed; the alarm module is connected to the end of the breaking cone exposed from the roadbed, and when the alarm module receives the signal of the laser transmitter at different heights, it feeds back different visible signals to the outside.

[0009] Through the above technical scheme, counterweights are used to increase the load on the roadbed below the earth-breaking cone. When the roadbed has insufficient bearing capacity due to dynamic compaction construction, the preferential sinking of the earth-breaking cone can be observed intuitively. Construction personnel can stop construction in time according to the degree of sinking of the earth-breaking cone to avoid large-scale settlement that may cause damage to construction personnel and construction machinery, thereby improving the objectivity of judging the hidden dangers of roadbed liquefaction during dynamic compaction construction.

[0010] In the present invention, the above-mentioned highway engineering construction hidden danger monitoring and inspection device also includes a cone head, which is detachably connected to one end of the earth-breaking cone inserted into the roadbed, the cone head is hard alloy, and the earth-breaking cone is stainless steel.

[0011] Through the above technical solution, a detachable carbide cone head is used to improve the placement efficiency of the earth-breaking cone and the interchangeability of the cone head, while the earth-breaking cone with a stainless steel body can effectively resist the corrosion of collapsible loess, thereby improving the durability of the device.

[0013] Through the above technical solution, filter holes and filter materials are used to reduce the direct contact between solid particles in the roadbed and the detection end of the pore water pressure meter, thereby ensuring the accuracy of pore water pressure measurement.

[0014] In the present invention, the filter material is a flexible material.

[0015] Through the above technical solution, the filter material made of flexible material is used to reduce the vibration of the pore water pressure gauge during the lowering operation of the breaking cone, thereby reducing the failure rate of the pore water pressure gauge.

[0016] In the present invention, the warning module includes a signal receiving module and an LED light strip, the signal receiving module is communicatively connected with the pore water pressure gauge, the signal receiving module has a first signal receiving area and a second signal receiving area, the first signal receiving area is located below the second signal receiving area; the LED light strip is arranged around the side wall of the warning module, and the LED light strip is communicatively connected with the signal receiving module;

[0017] When the first signal receiving area receives the laser signal emitted by the laser transmitter, the LED light strip changes color according to the pressure measured by the pore water pressure gauge;

[0018] When the second signal receiving area receives the laser signal emitted by the laser transmitter, the LED light strip lights up in a warning color.

[0019] Through the above technical solution, signal receiving areas at different heights are used to receive the laser signal emitted by the laser transmitter, so as to determine whether the sinking of the earth-breaking cone exceeds the safety threshold, and then the different lights of the LED light strip are used to visually warn the construction workers whether they can continue the construction. The judgment is simple and intuitive, and it is more convenient to use on the construction site.

[0020] In the present invention, the warning module comprises a smoke bottle, which is detachably connected to the upper end of the warning module. When the second signal receiving area receives the laser signal emitted by the laser transmitter, the smoke bottle releases smoke.

[0021] Through the above technical solution, a smoke bottle is used to issue an early warning when the subsidence of the earth-breaking cone exceeds the safety threshold, which has a better warning effect. At the same time, multiple people can collaborate to monitor the risk of roadbed liquefaction to avoid negligence caused by single-person operation, and further improve the safety of dynamic compaction construction.

[0022] In the present invention, the warning module comprises a solar panel, which is connected to the top of the warning module. The solar panel supplies power to the warning module and the pore water pressure gauge.

[0023] Through the above technical solution, solar panels are used to power the alarm module and the pore water pressure gauge, which reduces the wiring work at the construction site and further simplifies the installation and use of the monitoring device.

[0024] In the present invention, the solar cell panel is in a triangular shape, and three solar cell panels are connected in a pyramid shape.

[0045] Example:

[0046] Please refer to Figures 1 to 9 , Figures 1 to 9 An embodiment of the present application is shown.

[0047] This embodiment provides a device for monitoring and troubleshooting hidden dangers in highway engineering construction. Figures 1 to 4 as well as Fig. 9 As shown, it includes a laser transmitter 4 connected to the surface of the roadbed 5, a breaking cone 1, a pore water pressure gauge 103, a counterweight 102 and an alarm module 2. The breaking cone 1 is used to be inserted into the roadbed 5 during the dynamic tamping construction, and the end of the breaking cone 1 inserted into the roadbed 5 is conical; the pore water pressure gauge 103 is connected to the inner side of the breaking cone 1, and is used to monitor the pore water pressure flowing from the roadbed 5 into the breaking cone 1; the counterweight 102 is connected to the inner side of the breaking cone 1, and the counterweight 102 makes the load on the roadbed 5 below the breaking cone 1 greater than the design load of the roadbed 5 construction and less than the maximum load of the roadbed 5; the alarm module 2 is connected to the end of the breaking cone 1 exposed from the roadbed 5, and when the alarm module 2 receives the signal of the laser transmitter 4 at different heights, it feeds back different visible signals to the outside.

[0048] Before construction, the maximum load data of collapsible loess in the construction section is calculated through early soil sampling and hydrological observation, and the use load data of the construction section is determined. Then, the load under the breaking cone 1 during construction monitoring is determined between the use load and the maximum load data, such as Figure 3 and Figure 4 As shown, the pore water pressure gauge 103 is screwed into the internal thread of the mounting seat 105 connected to the ground-breaking cone 1, and then a lead counterweight block 102 is sleeved on the outer side of the mounting seat 105. By installing multiple counterweight blocks 102, the load below the ground-breaking cone 1 during monitoring is met, and then Fig. 9 As shown, the lower part of the breaking cone 1 is hammered into the node of the compaction area 501 planned in advance on the roadbed 5, and then the signal receiving module 202 is installed on the top of the breaking cone 1, and the height of the laser transmitter 4 is adjusted so that the fan-shaped laser beam it emits is directed to each signal receiving module 202.

[0049] During construction, the visible signal emitted by the signal receiving module 202 after each impact of the dynamic compaction construction is monitored to determine whether to continue the next compaction. Specifically, reference is made to the use of the pore water pressure gauge 103 in the patent with announcement number CN103205956B. Based on the degree of the pore water pressure gauge 103, the signal receiving module 202 releases a green light to prompt the construction personnel to continue compacting, and the signal receiving module 202 releases a yellow light to prompt the construction personnel to end compaction. When there is a tendency of liquefaction of the roadbed 5, the signal receiving module 202 emits a red light. At this time, the construction personnel and construction machinery need to evacuate the construction site in time.

[0050] It should be noted that in the prior art, there are multiple sensors that are used in combination to monitor the settlement of the roadbed 5, but the main purpose of the technical solution of this embodiment is to monitor that no large-scale obvious settlement occurs. At the same time, in order to meet the needs of construction personnel, rather than professional technicians for monitoring, the display of the results of the liquefaction tendency of the roadbed 5 is more intuitive. Construction personnel do not need to contact specific parameters for analysis, but only need to judge based on different signals, and the threshold for use is lower.

[0051] Through the above technical scheme, the counterweight block 102 is used to increase the load on the roadbed 5 below the earth-breaking cone 1. When the strong compaction construction causes the roadbed 5 to have insufficient bearing capacity, the earth-breaking cone 1 sinks first and can be observed intuitively. The construction personnel can directly stop the construction in time according to the degree of sinking of the earth-breaking cone 1 to avoid large-scale settlement that may cause damage to the construction personnel and construction machinery, thereby improving the objectivity of judging the liquefaction risk of the roadbed 5 during the strong compaction construction.

[0052] As a preferred implementation method, Figure 4 As shown, the above-mentioned highway engineering construction hidden danger monitoring and inspection device also includes a cone head 3, which is detachably connected to one end of the earth-breaking cone 1 inserted into the roadbed 5. The cone head 3 is hard alloy and the earth-breaking cone 1 is stainless steel.

[0053] Through the above technical solution, a detachable carbide cone head 3 is adopted to improve the insertion efficiency of the earth-breaking cone 1 and the interchangeability of the cone head 3, while the earth-breaking cone 1 with a stainless steel body can effectively resist the corrosion of collapsible loess, thereby improving the durability of the device.

[0054] As a preferred implementation method, Figure 2 and Figure 4 As shown, the above-mentioned highway engineering construction hidden danger monitoring and inspection device also includes filter holes 101 and filter materials 104, and a plurality of filter holes 101 are opened on the side wall of the conical end of the cone head 3; the filter material 104 is filled on the inner side of the conical end of the cone head 3, and the detection end of the pore water pressure meter 103 is inserted into the filter material 104.

[0055] Through the above technical solution, the filter holes 101 and the filter material 104 are used to reduce the direct contact between the solid particles in the roadbed 5 and the detection end of the pore water pressure meter 103, thereby ensuring the accuracy of the pore water pressure measurement.

[0056] As a preferred implementation, the filter material 104 is a flexible material, specifically a sponge or a sponge-like polymer material.

[0057] Through the above technical solution, the filter material 104 made of flexible material is used to reduce the vibration of the pore water pressure gauge 103 during the lowering operation of the breaking cone 1, thereby reducing the failure rate of the pore water pressure gauge 103.

[0058] As a preferred implementation method, Figures 5 to 7 As shown, the above-mentioned warning module 2 includes a signal receiving module 202 and an LED light strip 203. The signal receiving module 202 is communicatively connected with the pore water pressure gauge 103. The signal receiving module 202 has a first signal receiving area 2021 and a second signal receiving area 2022. The first signal receiving area 2021 and the second signal receiving area 2022 are both connected to the installation tube 201 made of transparent material, and the first signal receiving area 2021 is located below the second signal receiving area 2022; the LED light strip 203 is arranged around the side wall of the warning module 2, and the LED light strip 203 is communicatively connected with the signal receiving module 202;

[0059] When the first signal receiving area 2021 receives the laser signal emitted by the laser transmitter 4, the LED light strip 203 changes color according to the pressure measured by the pore water pressure meter 103;

[0060] When the second signal receiving area 2022 receives the laser signal emitted by the laser transmitter 4 , the LED light strip 203 lights up in a warning color.

[0061] During use, when the pressure does not exceed the threshold, the first signal receiving area 2021 receives the laser signal emitted by the laser emitter 4, and the LED light strip 203 lights up green. When the pressure gradually approaches the threshold, the LED light strip 203 gradually changes from green to yellow. When the second signal receiving area 2022 receives the laser signal emitted by the laser emitter 4, it indicates that the earth-breaking cone 1 has significantly settled. At this time, the LED light strip 203 lights up red, and a buzzer device can be added if necessary.

[0062] Through the above technical solution, signal receiving areas at different heights are used to receive the laser signal emitted by the laser transmitter 4, so as to determine whether the sinking of the earth-breaking cone 1 exceeds the safety threshold, and then the different lights of the LED light strip 203 are used to intuitively warn the construction personnel whether they can continue the construction. The judgment is simple and intuitive, and it is more convenient to use on the construction site.

[0063] As a preferred implementation method, Figure 6 and Figure 7 As shown, the above-mentioned warning module 2 includes a smoke bottle 204, which is detachably connected to the solenoid valve at the upper end of the warning module 2. When the second signal receiving area 2022 receives the laser signal emitted by the laser transmitter 4, the smoke bottle 204 releases smoke.

[0064] During use, when the second signal receiving area 2022 receives the laser signal emitted by the laser transmitter 4, the solenoid valve is activated to release the liquid ammonia in the smoke bottle 204. The liquid ammonia quickly vaporizes to produce a large amount of smoke accompanied by a pungent smell, which warns the construction workers both visually and olfactorily.

[0065] Through the above technical solution, the smoke bottle 204 is used to issue an early warning when the subsidence of the earth-breaking cone 1 exceeds the safety threshold, which has a better warning effect. At the same time, multiple people can also collaborate to monitor the liquefaction risk of the roadbed 5 to avoid negligence caused by single-person operation, thereby further improving the safety of dynamic compaction construction.

[0066] As a preferred implementation method, Figure 7 As shown, the alarm module 2 includes a solar panel 205 , which is connected to the top of the alarm module 2 . The solar panel 205 supplies power to the alarm module 2 and the pore water pressure meter 103 .

[0067] It should be noted that the use of solar panels 205 for power supply is a conventional means of the prior art, and therefore its supporting components including but not limited to the inverter accumulator are not described or limited here. Those skilled in the art can equip the solar panels 205 with relevant components based on the existing public technology to meet the power supply needs of the module. It should be emphasized here that the solar panels 205 need to be organically combined with the alarm module 2 and the pore water pressure gauge 103, and the purpose is to simplify the wiring at the construction site. This is done in response to the impact of the tamping construction on the roadbed 5 and the high height of the construction equipment, and there are safety hazards in both ground wiring and sky wiring.

[0068] Through the above technical solution, the solar panel 205 is used to power the alarm module 2 and the pore water pressure gauge 103, which reduces the wiring work at the construction site and further simplifies the installation and use of the monitoring device.

[0069] As a preferred implementation method, Figure 7 As shown, the solar cell panel 205 is triangular in shape, and three solar cell panels 205 are connected in a pyramid shape. A spherical protective cover 206 made of transparent glass is provided on the outside of the pyramid-shaped solar cell panel 205 .

[0070] When in use, construction workers do not need to adjust the specific direction of the entire device, making operation easier.

[0071] Through the above technical solution, three solar panels 205 connected in a pyramid shape are used to collect solar energy from multiple angles and improve power supply efficiency.

[0072] As a preferred implementation method, Figure 8 and Fig. 9 As shown, an anti-settling plate 401 is connected below the laser emitter 4 .

[0073] Through the above technical solution, the anti-settling plate 401 is used to improve the Z-axis coordinate stability of the laser emitter 4, thereby preventing the laser emitter 4 from sinking due to the impact of the tamping construction.

[0074] As a preferred implementation method, Figure 8 and Fig. 9 As shown, a plurality of positioning forks 402 are connected below the anti-settling plate 401 .

[0075] Through the above technical solution, the positioning fork 402 is used to improve the horizontal coordinate stability of the laser emitter 4, thereby preventing the laser emitter 4 from being horizontally displaced due to the impact of the tamping construction.

[0076] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
