Embodiment

[0027] Such as figure 2 As shown, the sensors are divided into six locations for layout. The sensors are divided into horizontal sensors on the drilling rig platform (position 1 in the figure), horizontal sensors on the top of the column (position 5 in the figure), and vertical sensors on the column (position 6 in the figure). , Motor current sensor (position 4 in the diagram), motor vertical sensor (position 3 in the diagram), and drill vertical sensor (position 2 in the diagram).

[0028] The level sensor of the drilling rig platform and the level sensor at the top of the column are installed on the horizontal direction of the L-shaped turnover plate 2 of the sensor installation box.

[0029] Column vertical sensor, motor vertical sensor, drill bit vertical sensor are installed on the vertical direction of L-shaped turning plate 2 of sensor installation box.

[0030] The motor current sensor is installed on the L-shaped turnover plate 2 of the sensor installation box.

Abstract

The invention discloses a dynamic monitoring system and device of foundation pit short hole drilling construction quality and belongs to the technical field of foundation pit safety construction equipment. A sensor mounting box comprise a flip-cover box body, an L-shaped flip plate, a pin, support posts, double-side adhesive and fastening screws. The dynamic monitoring system herein is characterized in that sensors, wireless transmitting-receiving modules and their quantities are selected according to related control principles and are fixedly mounted in specific positions; a computer softwaresystem acquires related data; the sensors connect data acquired at various monitoring points to the computer software system through the wireless transmitting-receiving modules; the computer softwaresystem records related parameters; foundation pit short hole forming data can be transmitted and processed in real time, construction deviation pre-warning is achieved, and dynamic displaying is provided for constructing; the system and device herein are widely applicable to drilling construction of the fields, such as foundation pits, slopes, coal mines, and tunnels; the system and device hereinare applicable to hole forming quality monitoring for oblique holes or horizontal holes.

Description

technical field [0001] The invention relates to the field of foundation pit drilling construction. Specifically, it is a monitoring system that controls the verticality of the hole, and can also correct the deviation at any time to ensure the construction quality. Background technique [0002] At present, support and foundation treatment operations in underground engineering construction are becoming more and more frequent. At present, there are problems such as difficult control and poor precision in the verticality control of drilling holes, resulting in poor hole quality, which brings safety belts to engineering construction and support. to hidden dangers. Contents of the invention [0003] The present invention provides a dynamic monitoring system for hole-forming quality. Using the device and system effectively avoids the disadvantage of poor verticality control of current hole-forming equipment, that is, the problem that the quality of drilling cannot be accurately ...
