Description

Technical Field

[0002] In the process of geotechnical engineering blasting, drilling accuracy is a key factor affecting the blasting quality. Traditional engineers or technicians often use borehole inclinometers and total stations to measure the deflection rate and spatial position relationship of each blasthole in the blasting design. Traditional inclinometers generally rely on gravity to slide the inclinometer probe from bottom to top in the inclinometer tube.

[0003] It has the following disadvantages:

[0004] 1. Traditional inclinometers mainly rely on gravity to perform section-by-section measurements along the pipe wall. In the field of geotechnical engineering blasting, blastholes are often arranged horizontally or from bottom to top, and traditional inclinometers are not applicable in this field.

[0005] 2. In the field of geotechnical engineering blasting, a total station is used to determine the relative positions of blast holes. The blast holes are arranged relatively densely and the measurement process is cumbersome.

[0006] 3. The blasthole inclination measurement can only obtain the deviation angle of a single blasthole, and the spatial position relationship of multiple blastholes can only be obtained by cooperating with the total station measurement data. The post-processing time of data is long, and it is impossible to achieve timely acceptance and guidance of production.

[0007] 4. Due to the complex conditions inside the hole, the waterproof requirements for the device are high, and traditional joints or overall packaging are easily damaged. Summary of the invention

[0033] like Figure 1-Figure 2 As shown, the purpose of the present invention is to provide a multi-blasthole three-dimensional model measurement device. The principle of the integrated total station and the traditional inclinometer is used to solve the problems of difficult blasthole precision measurement in the field of geotechnical engineering blasting, cumbersome measurement procedures, low measurement accuracy, and inapplicability of anti-gravity measurement.

[0034] When measuring, you only need to splice the corresponding units according to the length of the blasthole, and then poke into the blasthole and aim at the target, so that you can realize the real-time measurement and generation of multi-blasthole three-dimensional models, which can effectively guide the blasting construction design.

[0035] To achieve the above object, the present invention provides a multi-blasthole three-dimensional model measuring device, comprising semi-rigid inclinometer units that can be connected to each other during installation, two adjacent measuring units are connected by but not limited to threaded connections, and the bottom is connected to a positioning unit;

[0036] During measurement, three positioning targets are arranged on site in advance. The positioning unit and the inclinometer unit are connected as a whole and penetrate into the bottom of the blasthole. The laser positioning module is adjusted to align with the on-site target, and the number of the blasthole to be measured is input.

[0037] When recording data, press the record button, and the display and data processing package module can process the obtained blasthole number, positioning information and inclinometer unit angle information to form the corresponding blasthole relative three-dimensional space coordinate information.

[0038] Preferably, according to the three-dimensional space coordinate information, the similar trajectory line of the first measurement of the blasthole can be obtained as Functional relationship, the radius of the blasthole is Δα, and the possible spatial position relationship of the blasthole is The possible spatial position relationship of the blastholes obtained by the second measurement is: Based on the overlapping areas obtained from more than two measurements, the center points of the overlapping areas at each depth z are taken, and circles with a radius of Δα are drawn with each center point to finally obtain the precise value of the blasthole three-dimensional model.

[0039] Preferably, the inclinometer unit is made of a semi-rigid hose. The positioning unit is made of a hard waterproof material.

[0040] Preferably, the length of the inclinometer unit is determined according to actual on-site conditions and required model accuracy.

[0041] Preferably, an acceleration sensor is embedded inside the inclinometer unit and is located at the center of the unit.

[0042] Preferably, the inclinometer unit is divided into an end inclinometer unit and a middle inclinometer unit. The end inclinometer unit is sealed to prevent water. The threaded joints or other quick joints connected to other units are arranged at both ends of the middle inclinometer unit.

[0043] Preferably, data connection lines extend from two ends of the inclinometer unit to extend the connection of the inclinometer unit.

[0044] Preferably, the positioning unit is embedded with a laser positioning sensor, and the sensor can be rotated to adjust the angle for aligning with the target position.

[0045] Preferably, the laser positioning sensor is waterproof packaged.

[0046] Preferably, the positioning unit is embedded with a display and data processing encapsulation module, and integrates a single chip microcomputer and other related circuits.

[0047] Preferably, the positioning unit determines the relative spatial position coordinates of the unit based on the on-site arranged targets.

[0048] Preferably, the display and data processing packaging module can process and form the relative three-dimensional spatial coordinate information of the corresponding blasthole through the function selection button.

[0049] Workflow: First, clean the measured blasthole, and connect the positioning unit 3, the inclinometer unit 1 and the order according to the length of the blasthole. Then, arrange at least 3 targets 4 at different positions without obstructions at the measurement site. Extend the assembled measuring device into the blasthole 2, and then turn on the positioning unit. Rotate the laser positioning module 5 to align with the target 4. Enter the number of the measured blasthole. Since the semi-rigid inclinometer unit will produce different angle changes with the deflection of the blasthole, it will drive the internal angle sensor to change, and then pass through the data transmission line. The data processing packaging module performs data analysis and records the relative three-dimensional space coordinate information of each measured blasthole. Each blasthole is measured at least twice, and the measurement is finally completed. After the measurement is completed, take out the measuring device, disassemble and recycle it. At the same time, after the measurement is completed, the data is transmitted to the host computer to display the three-dimensional model generation result.
