Description

Technical Field

[0001] The present application relates to the technical field of road construction, and specifically discloses a road construction surveying device and method. Background Art

[0002] In road construction, geotechnical sampling and survey is a vital link. First, through geotechnical sampling and survey, we can understand the geological conditions, environmental characteristics and geotechnical conditions of the construction site, so as to provide a scientific basis for the construction of road projects, which is the geographical environment basis for the planning of all engineering projects; secondly, through sampling and survey of geotechnical, potential geological problems can be discovered and dealt with in time to avoid safety hazards during the construction process, thereby ensuring the quality and safety of the project; and in-situ tests and indoor tests in geotechnical engineering surveys can provide accurate geotechnical parameters and provide a reliable basis for engineering design, which helps to reduce engineering risks and avoid engineering accidents caused by unclear geological conditions; and geotechnical engineering surveys can also assess environmental impacts. Through sampling and survey, we can understand the extent of the impact of the construction process on the surrounding environment, so as to take corresponding measures to reduce damage to the environment and protect the ecological environment.

[0003] At present, in the process of sampling and surveying rock and soil, according to the selected survey area, the sampling area is firstly subjected to exploration methods such as drilling, well exploration, trench exploration and cave exploration, and rock and soil samples are obtained from exploration holes, trenches, exploration wells and other locations for indoor testing and analysis. Taking drilling as an example, the current more common drilling process is: the staff first drills holes in the survey area through equipment such as a drilling rig, and then collects the rock and soil drilled out during the drilling process and the rock and soil finally remaining in the exploration hole. Finally, the collected samples are subjected to indoor testing and analysis to obtain the survey results. However, the process has the following problems: first, the drilling working environment is poor, and the dust generated during the drilling process is directly dispersed into the air, causing pollution to the surrounding environment. Secondly, the construction method of drilling first and then collecting is not only inefficient, but also the rock and soil at different depths are easily mixed with each other and even polluted by the external environment, thereby affecting the readiness of the final experimental analysis, resulting in large errors in the survey results. Therefore, in view of this, the inventor provides a road construction survey device and method to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the traditional geotechnical survey process, when sampling rock and soil, the dust generated during the drilling process directly floats into the air, causing pollution to the surrounding environment.

[0005] In order to achieve the above object, the basic scheme of the present invention provides a road construction survey device, comprising:

[0006] Surveying frame;

[0007] A sleeve is arranged on the survey frame, the bottom of the sleeve is in contact with the survey ground, and the top of the sleeve is provided with an end cover;

[0008] The drilling mechanism comprises a power member arranged on the survey frame, a main shaft driven to rotate by the power member and vertically slide along the end cover, and a drill rod arranged at one end of the main shaft located in the sleeve;

[0009] The sampling pipeline is arranged on the end cover and communicated with the interior of the sleeve.

[0010] The principles and effects of this basic solution are:

[0011] Compared with the prior art, the present invention provides a sleeve so that when the bottom of the sleeve fits against the surveyed ground, a closed environment is formed inside the sleeve, so that sampling is performed through the sampling pipe while drilling a hole in the surveyed ground through the drill rod; and due to the provision of the sleeve, the drilling position of the borehole is located inside the sleeve, which can effectively prevent the dust generated during the drilling process from directly drifting into the air, thereby protecting the surrounding environment, and also preventing the external environment from polluting the surveyed rock and soil; and the present invention adopts a method of synchronously performing drilling and rock and soil collection, which can accurately and effectively collect rock and soil of different depths and classify them, thereby avoiding the problem of rock and soil of different depths mixing with each other.

[0012] Furthermore, the side wall of the drill rod is provided with a sealing plate that is slidably and sealedly connected to the inner wall of the sleeve, and a telescopic pipe is provided between the bottom of the sealing plate and the sampling pipe. By providing the sealing plate and the telescopic pipe, a relatively narrow and closed space is formed between the sealing plate, the sleeve and the surveyed ground, so that it is convenient to use the pipe to collect rock and soil samples generated during drilling.

[0013] Furthermore, the inner wall of the sleeve is evenly provided with a plurality of guide strips, and the peripheral end of the sealing plate is evenly provided with a plurality of guide grooves adapted to the guide strips. The cooperation between the guide strips and the guide grooves plays a role of limiting and guiding the sliding of the sealing plate.

[0014] Furthermore, the sleeve includes a fixed cylinder connected to the end cover and a sliding cylinder slidably connected to the fixed cylinder, and a switching assembly is provided between the sealing plate and the drill rod, which can make the sealing plate and the drill rod rotate synchronously or relatively. Through this arrangement, when the sealing plate and the drill rod rotate synchronously, the sliding cylinder is driven to rotate by the cooperation between the guide bar and the guide groove, thereby improving the tightness of the contact between the sliding cylinder and the surveyed ground, thereby improving the sampling effect of the rock and soil and reducing the diffusion of dust.

[0015] Furthermore, the inner wall of the sliding cylinder is symmetrically provided with a smooth transition curved groove, and the outer wall of the sliding cylinder is symmetrically provided with a sliding block slidably connected in the curved groove, and the curved groove includes horizontal sections respectively located at both ends of the groove and having a height difference, and a lifting section arranged between the horizontal sections;

[0016] When the sealing plate and the drill rod rotate synchronously, the slider is slidably connected in the lifting section; when the sealing plate and the drill rod rotate relatively, the slider is slidably connected in the horizontal section.

[0017] With this arrangement, when the sealing plate and the drill rod rotate synchronously, the sliding cylinder is driven to rotate, and the cooperation between the slider and the curved groove is used to make the sliding cylinder rise and fall vertically, so that the bottom of the sliding cylinder is closely fitted to the surveyed ground. When the sealing plate and the drill rod rotate relatively, the slider is located in the horizontal section and limits the horizontal rotation and vertical lifting of the sliding cylinder, so that the cooperation between the sliding cylinder and the surveyed ground is more stable.

[0018] Further, the switching component includes:

[0019] A connection box is connected to the sealing plate, and a plurality of slots are evenly arranged at the bottom of the connection box, and a plurality of electromagnets are arranged in the connection box and are respectively located above each slot;

[0020] A rotating sleeve is key-connected to the drill rod, and a pin which can be attracted by an electromagnet and extended into a card slot is vertically slidably connected to the top of the rotating sleeve;

[0021] When the electromagnet is energized, the pin extends into the slot, so that the connection box and the sealing plate rotate synchronously with the rotating sleeve.

[0022] By utilizing the mutual cooperation between the electromagnet and the pin and turning the electromagnet on and off, the pin can be extended into the slot under the action of magnetic force or fall out of the slot under the action of gravity, thereby facilitating the synchronous rotation of the sealing plate and the drill rod or the relative rotation of the sealing plate and the drill rod.

[0023] Furthermore, a connecting sleeve that is slidably connected to each other is provided between the sealing plate and the cover plate, and a conductive ring that can be electrically connected is provided between the contact surfaces of the connecting sleeve, and when the two conductive rings are in contact with each other, the electromagnet is energized. Through the provision of the conductive ring, the power on and off of the adjusting electromagnet can be adjusted according to the height of the movement of the sealing plate, and the height of the movement of the sealing plate is affected by the rotation of the drill rod, and affects the rotation and movement of the sliding cylinder, so that the power on and off of the electromagnet is adapted to the movement trajectory of the sliding cylinder.

[0024] Furthermore, a plurality of telescopic rods are evenly arranged along the radial direction at the peripheral end of the rotating sleeve, and a brush plate is arranged on the telescopic rod to brush along the inner wall of the sleeve. With this arrangement, not only can the inner wall of the sleeve be brushed by the brush plate, but also when the telescopic rod contacts the guide bar, it will be squeezed by the guide bar, and the elastic potential energy of the telescopic rod drives the brush plate to vibrate, thereby shaking off the rock and soil adhering to the brush plate.

[0025] Based on the same inventive concept, the present invention provides a road construction survey method, comprising the following steps:

[0026] Step S1, determining the survey area according to the scope involved in the road construction;

[0027] Step S2, using the above-mentioned surveying device to perform rock and soil drilling sampling in the survey area;

[0028] Step S3, conducting indoor tests on the obtained rock and soil samples to determine their physical properties, mechanical properties and chemical properties.

[0029] Furthermore, in step S2, after the bottom of the sleeve is fitted with the surveyed ground, a closed environment is formed in the sleeve, and the power component drives the drill rod to rotate through the main shaft to drill a hole in the surveyed ground, and sampling is performed through the sampling pipe at the same time.

[0030] This method forms a closed environment in the sleeve when the bottom of the sleeve fits against the surveyed ground, so that sampling can be carried out through the sampling pipe while drilling a hole in the surveyed ground through the drill rod; and the drilling position of the hole is located in the sleeve, which can effectively prevent the dust generated during the drilling process from directly drifting into the air, thereby protecting the surrounding environment and preventing the external environment from polluting the surveyed rock and soil; and the present invention adopts a method of synchronously performing drilling and rock and soil collection, which can accurately and effectively collect rock and soil at different depths and classify them, thereby avoiding the problem of rock and soil at different depths mixing with each other.

[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0040] The figure marks in the drawings of the specification include: exploration frame 1, fixed cylinder 2, sliding cylinder 3, end cover 4, motor bracket 5, motor 6, first transmission shaft 7, second transmission shaft 8, threaded seat 9, drill rod 10, sampling pipe 11, telescopic pipe 12, sealing plate 13, guide bar 14, guide groove 15, curved groove 16, horizontal section 1601, lifting section 1602, rotating sleeve 17, fixed rod 18, sliding rod 19, brush plate 20, first connecting sleeve 21, second connecting sleeve 22, conductive ring 23, card slot 24, electromagnet 25, pin 26, connecting box 27.

[0041] A road construction survey device and method, for example Figure 1 As shown: it includes an exploration frame 1, a sleeve arranged on the exploration frame 1, and a drilling mechanism and a sampling pipeline 11 arranged on the sleeve, which are specifically as follows:

[0042] Exploration frame 1: The exploration frame 1 is formed by welding a plurality of symmetrically arranged alloy steels to each other and supported by legs, and a universal wheel with a brake pad is arranged at the bottom of the legs.

[0043] Sleeve: The sleeve includes a fixed cylinder 2 fixed to the exploration frame 1, a sliding cylinder 3 slidably connected to the inner wall of the fixed cylinder 2, and an end cover 4 arranged on the top of the fixed cylinder 2. In this embodiment, curved grooves 16 are symmetrically arranged on the inner walls of the front and rear sides of the fixed cylinder 2. The curved groove 16 includes horizontal sections 1601 respectively located at the ends of the groove and having a height difference, and a lifting section 1602 arranged between the horizontal sections 1601. There is a smooth transition between the horizontal section 1601 and the lifting section 1602. Slide blocks slidably connected along the curved grooves 16 are symmetrically arranged on the outer walls of the front and rear sides of the sliding cylinder 3. A toothed surface is arranged at the bottom of the sliding cylinder 3 to extend into the ground for fixation.

[0044] Drilling mechanism: The drilling mechanism includes a power member arranged on the survey frame, a main shaft driven by the power member to rotate and slide vertically along the end cover 4, and a drill rod 10 arranged at one end of the main shaft located in the sleeve. In this embodiment, the power member adopts a motor 6, which is fixedly installed with the end cover 4 through a motor bracket 5. The main shaft includes a first transmission shaft 7 and a second transmission shaft 8. The top of the first transmission shaft 7 is connected to the output shaft of the motor 6 through a coupling, the bottom of the first transmission shaft 7 is splined to the second transmission shaft 8, the outer wall of the second transmission shaft 8 is threadedly connected to the threaded seat 9 arranged on the end cover 4, and the bottom of the second transmission shaft 8 extends into the sleeve and is connected to the drill rod 10 through a coupling.

[0045] With this arrangement, when the motor 6 rotates, it drives the first transmission shaft 7, the second transmission shaft 8 and the drill rod 10 to rotate synchronously. At the same time, the threaded fit between the second transmission shaft 8 and the threaded seat 9 enables the second transmission shaft 8 to drive the drill rod 10 to move vertically.

[0046] A sealing plate 13 is vertically slidably connected to the inner wall of the sliding cylinder 3. Correspondingly, a plurality of guide strips 14 are evenly arranged on the inner wall of the sleeve, and a plurality of guide grooves 15 adapted to the guide strips 14 are evenly arranged on the peripheral end of the sealing plate 13, so as to limit and guide the sliding of the sealing plate 13.

[0047] The sampling pipe 11 is arranged on the end cover 4 and communicated with the inside of the sleeve. A telescopic pipe 12 is arranged between the bottom of the sealing plate 13 and the sampling pipe 11. The end of the sampling pipe 11 is connected to a ventilator and a collecting box, so as to suck out the rock and soil samples generated during the drilling process.

[0048] When the sliding cylinder 3 rotates, the state of the telescopic pipe 12 will be twisted, which may cause damage to the contact between the telescopic pipe 12 and the threaded surface on the outside of the second transmission shaft 8. In this embodiment, the telescopic pipe 12 adopts a flexible pipe, and a connecting sleeve is provided between the sealing plate 13 and the cover plate, which are slidably connected to each other and cover the second transmission shaft 8. For the convenience of description, the first connecting sleeve 21 is connected to the cover plate, and the second connecting sleeve 22 is connected to the sealing plate 13, so that the telescopic pipe 12 is in contact with the first connecting sleeve 21 and the second connecting sleeve 22 when it is twisted.

[0049] In this embodiment, the angle between the ends of the curved groove 16 and the center of the sliding cylinder 3 is less than 180°, so that the rotation angle of the sliding cylinder 3 is less than 180°, thereby reducing the rotation angle of the sliding cylinder 3, that is, reducing the degree of distortion of the telescopic pipe 12.

[0050] The rotation of the sliding cylinder 3 is driven by the sealing plate 13. When the sealing plate 13 rotates, the cooperation between the guide bar 14 and the guide groove 15 is no longer to limit and guide the sealing plate 13, but to transmit power to drive the sliding cylinder 3 to rotate.

[0051] The rotation of the sealing plate 13 is driven by the drill rod 10. In this embodiment, the matching relationship between the sealing plate 13 and the drill rod 10 has two states, namely, the sealing plate 13 and the drill rod 10 rotate synchronously and the sealing plate 13 and the drill rod 10 rotate relative to each other. The switching is performed by the switching component.

[0052] The switching assembly includes a connection box 27 fixed at the bottom of the sealing plate 13 and a rotating sleeve 17 key-connected to the drill rod 10. A plurality of slots 24 are evenly arranged at the bottom of the connection box 27. A plurality of electromagnets 25 are arranged in the connection box 27 and are respectively located above each slot 24. A pin 26 which can be absorbed by the electromagnet 25 and extended into the slot 24 is vertically slidably connected to the top of the rotating sleeve 17. By turning the electromagnet 25 on and off, the pin 26 can be extended into the slot 24 under the action of magnetic force or fall out of the slot 24 under the action of gravity, thereby facilitating the synchronous rotation of the sealing plate 13 and the drill rod 10 or the relative rotation of the sealing plate 13 and the drill rod 10.

[0053] The power on and off of the electromagnet 25 is controlled by two conductive rings 23 respectively arranged on the outer wall of the first connecting sleeve 21 and the inner wall of the second connecting sleeve 22. Correspondingly, one end of the electromagnet 25 is connected to the positive pole of the power supply, the other end of the electromagnet 25 is connected to one of the conductive rings 23, and the negative pole of the power supply is connected to the other conductive ring 23, so that when the two conductive rings 23 are in contact with each other, the electromagnet 25 is energized, that is, a circuit is formed between the electromagnet 25 and the battery.

[0054] The setting of the conductive ring 23 can adjust the power on and off of the adjusting electromagnet 25 according to the height of the movement of the sealing plate 13, and the height of the movement of the sealing plate 13 is affected by the rotation of the drill rod 10, and affects the rotation and movement of the sliding cylinder 3, so that the power on and off of the electromagnet 25 are adapted to the movement trajectory of the sliding cylinder 3, that is, when the slider on the outer wall of the sliding cylinder 3 is located in the horizontal section 1601 at the top of the curved groove 16, the two conductive rings 23 contact each other, so that the electromagnet 25 is energized, and the pin 26 extends into the card slot 24 under the action of the magnetic force, and the sealing plate 13 and the drill rod 10 rotate synchronously, driving the sliding cylinder 3 to rotate The slider moves along the curved groove 16, driving the sliding cylinder 3 to move downward, so that the sliding cylinder 3 is fixed in the ground until the slider moves to the horizontal section 1601 at the bottom of the curved groove 16. At this time, the sliding cylinder 3 stops moving vertically and maintains synchronous rotation with the sealing plate 13, but the sealing plate 13 continues to move downward under the drive of the drill rod 10, thereby driving the second connecting sleeve 22 to move downward, causing the two conductive rings 23 to separate from each other, and the slider moves to the end of the horizontal section 1601. After the two conductive rings 23 separate from each other, the sealing plate 13 and the drill rod 10 rotate relative to each other, and the drill rod 10 slides vertically along the sliding cylinder 3.

[0055] In this embodiment, a plurality of telescopic rods are evenly arranged radially around the circumferential end of the rotating sleeve 17, and the telescopic rods include a fixed rod 18 connected to the rotating sleeve 17 and a sliding rod 19 slidably connected to the fixed rod 18. An elastic contact is provided at the end of the sliding rod 19, and a brush plate 20 is provided on the sliding rod 19 for brushing along the inner wall of the sleeve. One end of the sliding rod 19 extends into the fixed rod 18 and is provided with a spring. The inner wall of the sleeve is brushed by the brush plate 20, and when the telescopic rod contacts the guide bar 14, it will be squeezed by the guide bar 14, and the elastic potential energy of the telescopic rod drives the brush plate 20 to vibrate, thereby shaking off the rock and soil adhered to the brush plate 20.

[0056] Based on the same inventive concept, the present invention provides a road construction survey method, comprising the following steps:

[0057] Step S1, determining the survey area according to the scope involved in the road construction;

[0058] Step S2, using the above-mentioned surveying device to perform rock drilling and soil sampling in the survey area, when the motor 6 drives the drill rod 10 to rotate and slide vertically, the conductive rings 23 are first connected to each other, so that the sealing plate 13 drives the sliding cylinder 3 to move downward under the drive of the drill rod 10, and after the bottom of the sliding cylinder 3 is inserted into the surveyed ground, a closed environment is formed between the sliding cylinder 3, the surveyed ground and the sealing plate 13, so that when the motor 6 drives the drill rod 10 to drill, the suction force of the fan timely extracts the rock and soil samples in the drilling process;

[0059] Step S3, conducting indoor tests on the obtained rock and soil samples to determine their physical properties, mechanical properties and chemical properties.

[0060] Compared with the prior art, the present invention sets a sleeve so that when the bottom of the sleeve fits against the surveyed ground, a closed environment is formed inside the sleeve, so that sampling is performed through the sampling pipe 11 while drilling the surveyed ground through the drill rod 10; and due to the setting of the sleeve, the drilling position of the borehole is located inside the sleeve, which can effectively prevent the dust generated during the drilling process from directly drifting into the air, thereby protecting the surrounding environment, and also preventing the external environment from polluting the surveyed rock and soil; and the present invention adopts a method of synchronously performing drilling and rock and soil collection, which can accurately and effectively collect rock and soil of different depths and classify them, thereby avoiding the problem of rock and soil of different depths mixing with each other.

[0061] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
