Description

CFG pile driver construction pile driving depth monitoring system

Technical field

The invention relates to a digital construction monitoring device-CFG pile driver system. The system has comprehensive functions, reliable performance and easy use.

Background technique

In recent years, national infrastructure monitoring has been in full swing in various places, and more scientific construction process monitoring methods are the guarantee of construction quality. The gravel pile machine construction piling depth monitoring system was born. At present, the flow monitoring system on the market is mainly for measuring the construction pile pipe without pile pipe nesting, such as the gravel pile machine; when most of the gravel on the market is in operation, the construction depth is completely observed by the naked eye, and the accuracy is low. The error is large, and the monitoring requirements cannot be met, which brings great hidden dangers to the quality of the project.

Summary of the invention

In order to solve the above shortcomings, the present invention provides a CFG pile machine construction pile driving depth monitoring system, to overcome the above-mentioned existing technical shortcomings, adopt the laser distance measurement sensor installed on the gravel pile machine, through the measurement of the top of the pile machine support to the pile The distance between the pipe head and the various dimensions of the pile driver itself are used to calculate the depth of the current pile driver’s hammer head below the ground. With the user as the center, the precise control of the pile driver’s piling depth can be achieved during the entire piling process. Control, reduce the error of artificial judgment of pile depth, improve the construction quality of the project, and improve the level of construction technology.

The invention provides a CFG pile driver construction pile driving depth monitoring system, which adopts a laser ranging sensor installed on the gravel pile driver to measure the distance from the top of the pile driver support to the pile pipe head, and combine the size of the pile driver and the direction of the pile driver. The depth information of the pile head is calculated, and the current pile depth is displayed inside the software. The pile depth value is monitored in real time when the pile is pulled out. When the critical value is reached, the operator will be prompted and warned by sound and light alarms and screen flashing.

In the above system, a wired communication method is used, and a device function diagnosis function is implemented.

In the above system, the data collected by the laser ranging sensor is calculated by the data receiving and calculating module.

In the above system, the depth information of the pile head is calculated by the algorithm calculation module.

In the above-mentioned system, the calculation result is displayed through the display module, and then the operator is prompted and warned in the form of sound and light alarm and screen flashing.

The invention provides a CFG pile driver construction pile driving depth monitoring system with the following beneficial effects: it is user-centric, realizes accurate control of the pile driving depth during the entire process of piling, reduces the error of artificial judgment of pile depth, and improves the project The construction quality is improved, and the construction technology level is improved. The laser distance measuring sensor is installed on the gravel pile machine, and the current pile is calculated by calculating the distance from the top of the pile machine support to the pile pipe head. The depth of the hammer head into the ground, combined with the size of the pile driver and the direction of the pile driver, accurately calculates the depth information of the pile head, and displays the current pile depth inside the software, and monitors the pile depth value in real time when the pile is pulled out. When the critical value is reached, the operator will be prompted and warned by sound and light alarm, screen flashing, etc.
