Description

Technical Field

[0001] The invention relates to the field of municipal engineering, and in particular to a drilling device for assisting in determining the position of a dark well and a dark well drilling method. Background Art

[0002] Due to municipal construction, especially greening construction, many cities in my country have covered some manhole covers in some drainage systems, and some of them are covered deeply. However, since many pipe networks in the past were not constructed strictly in accordance with the construction drawings, and the completion drawings were not standardized, it was impossible to use the construction drawings or completion drawings to obtain accurate well locations. Conventional practices include using metal detectors to detect manhole covers in dark wells, but metal detectors can only detect metal manhole covers and are not applicable to manhole covers made of other materials; another more accurate device is a guide instrument, but CCTV or other robots are required to send carbon rods into the dark well, which generally requires blocking and precipitation, and is not applicable or has poor effects for pipe sections with deep buried depths, severe siltation, or inability to block and precipitate (such as large water volume or long distances without manhole covers). When the above methods are not applicable, the location of the covered manhole cover is often roughly analyzed based on existing data, and then mechanical or manual excavation is carried out, but direct large-scale excavation will damage and disturb a large area, and the cost of restoring greening is also large. It is also not conducive to safety control when the coverage is deep. CN202020219432U discloses a counting device for a drilling probe and a drilling probe, which control the falling or rising of a drilling rod. However, the drilling rod is driven by hammering, which easily causes damage to the cover of a dark well, and cannot be directly used for drilling the cover of a dark well. Summary of the invention

[0005] In a preferred solution, the vertical telescopic mechanism is a jack.

[0006] In a preferred embodiment, the steel drill mechanism also includes a multi-section extension rod, the upper ends of the extension rod and the steel drill are both provided with external threads, the lower end of the extension rod is provided with a connecting tube, the inner side of the connecting tube is provided with an internal thread, and the connecting tube is threadedly connected to the adjacent extension rod or steel drill.

[0007] In a preferred solution, a first slide rail is provided on the upper side of the frame, the vertical telescopic mechanism is installed on the first slide assembly, and the first slide assembly moves along the first slide rail.

[0008] In a preferred solution, two sets of second slide rails are arranged on the frame, the second slide rails are provided with second sliding components cooperating therewith, and both ends of the first slide rails are connected to the second sliding components.

[0009] The present invention also provides a dark well drilling method, which uses a drilling device for assisting in determining the position of the dark well to perform drilling, and comprises the following steps:

[0010] Step 1: According to the preliminary judgment of the approximate location and coverage depth of the dark well, combined with the location of other pipelines, plan the range of steel drill insertion, and set the steel drill insertion spacing, depth and pressure limit for stopping insertion according to the soil quality and the approximate coverage depth of the dark well;

[0011] Step 2: Move the drilling equipment to the planned drilling position, calibrate the pressure sensor, and use the vertical telescopic mechanism to insert the steel drill into the soil layer point by point;

[0012] Step 3. When the steel drill is inserted to the set depth, the central computer controls the vertical telescopic mechanism to pull out the steel drill and insert it from the next point; when the steel drill is not inserted to the set depth, but the pressure value detected by the pressure sensor has reached the set pressure limit, the central computer controls the vertical telescopic mechanism to pull out the steel drill and increase the number of drill probes around this point.

[0013] The preferred scheme also includes step four, in which the central computer forms a three-dimensional graph for the points that have not been inserted to the set depth but the pressure value of the pressure sensor has reached the set pressure limit. If the tips of some or all of the steel drills in the three-dimensional graph are basically in the same plane and form a circle that is close to the size of the manhole cover, it is preliminarily determined that the circular area is the location of the hidden well cover, and then the drilling is stopped, and the manhole cover is dug out manually or mechanically; if the tips of the steel drills in the three-dimensional graph are not in the same plane or are in the same plane but do not form a circle, it is necessary to continue drilling until the tips of some or all of the steel drills in the three-dimensional graph are basically in the same plane and form a circle that is close to the size of the manhole cover.

[0014] The present invention provides a drilling device and a method for drilling a dark well for assisting in determining the location of a dark well, which are used for exploring dark wells in a drainage system. The device is suitable for use when the manhole cover is covered and when precise positioning equipment such as a guide instrument cannot be used.

[0021] Example 1: Figure 1~2 As shown, a drilling device for assisting in determining the location of a dark well includes a frame 1, a running wheel 2 is provided at the bottom of the frame 1, and the running wheel 2 is a wheel with a built-in locking mechanism. A vertical telescopic mechanism 3 is provided on the frame 1, and a steel drill mechanism is provided at the telescopic end of the vertical telescopic mechanism 3. Specifically, a mounting frame is provided at the telescopic end of the vertical telescopic mechanism 3, and the steel drill mechanism is installed on the mounting frame. In this embodiment, the vertical telescopic mechanism 3 uses a jack, and the jack can also be replaced by a hydraulic cylinder, etc. The steel drill mechanism includes a steel drill 4, and a pressure sensor 5 is provided in the middle of the steel drill 4. The pressure sensor 5 is electrically connected to the central computer.

[0022] The specific use includes the following steps:

[0023] Step 1: According to the preliminary judgment of the approximate location and coverage depth of the dark well, ask the relevant pipeline ownership units such as weak current, strong current, gas, and water supply to conduct pipeline briefing and mark the location of the pipeline to avoid accidental damage to other pipelines when the steel drill is inserted. In combination with the location of other pipelines, plan the insertion range of the steel drill 4, and set the insertion spacing, depth, and pressure limit for stopping the insertion of the steel drill 4 according to the soil quality and the approximate coverage depth of the dark well.

[0024] Step 2: Move the drilling equipment to the planned drilling position, stop moving and lock it, and apply counterweight pressure according to the planned insertion depth and soil bearing capacity. Calibrate the pressure sensor 5, install the steel drill mechanism on the mounting frame at the telescopic end of the vertical telescopic mechanism 3, and use the vertical telescopic mechanism 3 to insert the steel drill 4 into the soil layer point by point.

[0025] Step 3: When the steel drill 4 is inserted to the set depth, the central computer controls the vertical telescopic mechanism 3 to pull out the steel drill 4 and insert it from the next point; when the steel drill is not inserted to the set depth, but the pressure value detected by the pressure sensor 5 has reached the set pressure limit, the central computer controls the vertical telescopic mechanism 3 to pull out the steel drill 4, and the drill probe is increased around the point. According to the coverage range of the drill probe point measured when the steel drill is not inserted to the set depth, but the pressure value detected by the pressure sensor 5 has reached the set pressure limit, the dark well position is drilled. If the coverage range is circular, it is preliminarily determined to be a dark well position, and subsequent excavation can be carried out. If the coverage range does not form a circle, the drill probe is continued.

[0026] Preferably, the central computer will form a three-dimensional graph for the points where the drill bit has not been inserted to the set depth but the pressure value of the pressure sensor 5 has reached the set pressure limit. If the tips of some or all of the steel drill bits 4 in the three-dimensional graph are basically in the same plane and form a circle that is close to the size of the manhole cover, it is preliminarily determined that the circular area is the location of the hidden well cover, and then the drilling is stopped, and the manhole cover is dug out manually or mechanically; if the tips of the steel drill bits 4 in the three-dimensional graph are not in the same plane or are in the same plane but do not form a circle, it is necessary to continue drilling until the tips of some or all of the steel drill bits in the three-dimensional graph are basically in the same plane and form a circle that is close to the size of the manhole cover.

[0027] The device and the blind well drilling method are used for searching blind wells in drainage systems. They are suitable for situations where the well cover is covered and precise positioning equipment such as guide instruments cannot be used. The device can be used instead of manual or mechanical excavation to quickly search for the position of the well cover within a certain range.

[0028] Embodiment 2: Different from embodiment 1, as Figure 3 As shown, the steel drill mechanism also includes a multi-section extension rod 6, the upper ends of the extension rod 6 and the steel drill 4 are both provided with external threads, the lower end of the extension rod 6 is provided with a connecting tube 601, the inner side of the connecting tube 601 is provided with an internal thread, and the connecting tube 601 is threadedly connected to the adjacent extension rod 6 or steel drill 4.

[0029] The multi-section extension rods 6 are interconnected, and the end extension rod 6 is connected to the steel drill 4, so that the length of the steel drill mechanism can be easily adjusted. According to the predicted depth of the dark well, the appropriate number of extension rods 6 is selected to adjust the total length of the steel drill mechanism.

[0030] Preferably, Figure 4 As shown, a first slide rail 7 is provided on the upper side of the frame 1 , and the vertical telescopic mechanism 3 is mounted on a first sliding assembly 8 , and the first sliding assembly 8 moves along the first slide rail 7 .

[0031] Two sets of second slide rails 9 are arranged on the vehicle frame 1 . The second slide rails 9 are provided with second sliding components 10 which cooperate with them. Both ends of the first slide rails 7 are connected to the second sliding components 10 .

[0032] The second slide rail 9 is arranged perpendicular to the first slide rail 7. By arranging the first slide rail 7 and the second slide rail 9, it is convenient to adjust the position of the vertical telescopic mechanism 3, thereby facilitating the adjustment of the position of the probe.

[0033] The specific use includes the following steps:

[0034] Step 1: According to the preliminary judgment of the approximate location and coverage depth of the dark well, ask the relevant pipeline ownership units such as weak current, strong current, gas, and water supply to conduct pipeline briefing and mark the location of the pipeline to avoid accidental damage to other pipelines when the steel drill is inserted. In combination with the location of other pipelines, plan the insertion range of the steel drill 4, and set the insertion spacing, depth, and pressure limit for stopping the insertion of the steel drill 4 according to the soil quality and the approximate coverage depth of the dark well.

[0035] Step 2: Move the drilling equipment to the planned drilling position, stop moving and lock it, and apply counterweight back pressure according to the planned insertion depth and soil bearing capacity. Calibrate the pressure sensor 5, install the steel drill mechanism on the mounting frame at the telescopic end of the vertical telescopic mechanism 3, use the vertical telescopic mechanism 3 to insert the steel drill 4 into the soil layer point by point, and adjust the position of the steel drill 4 by moving the vertical telescopic mechanism 3 along the first slide rail 7 and the first slide rail 7 along the second slide rail 9.

[0036] Step 3: When the steel drill 4 is inserted to the set depth, the central computer controls the vertical telescopic mechanism 3 to pull out the steel drill 4 and insert it from the next point; when the steel drill is not inserted to the set depth, but the pressure value detected by the pressure sensor 5 has reached the set pressure limit, the central computer controls the vertical telescopic mechanism 3 to pull out the steel drill 4, and the drill probe is increased around the point. According to the coverage range of the drill probe point measured when the steel drill is not inserted to the set depth, but the pressure value detected by the pressure sensor 5 has reached the set pressure limit, the dark well position is drilled. If the coverage range is circular, it is preliminarily determined to be a dark well position, and subsequent excavation can be carried out. If the coverage range does not form a circle, the drill probe is continued.

[0037] Preferably, the central computer will form a three-dimensional graph for the points where the drill bit has not been inserted to the set depth but the pressure value of the pressure sensor 5 has reached the set pressure limit. If the tips of some or all of the steel drill bits 4 in the three-dimensional graph are basically in the same plane and form a circle that is close to the size of the manhole cover, then the circular area is the position of the hidden well cover. Then the drilling is stopped and the manhole cover is dug out manually or mechanically. If the tips of the steel drill bits 4 in the three-dimensional graph are not in the same plane or are in the same plane but do not form a circle, then the drilling needs to be continued until the tips of some or all of the steel drill bits in the three-dimensional graph are basically in the same plane and form a circle that is close to the size of the manhole cover.
