Problems solved by technology

In this process, errors caused by human factors are unavoidable, and the on-site supervisors’ stand-by records and the statistical analysis of later data require a lot of manpower, and the risk and cost of construction quality control are relatively large. Therefore, the traditional method has obvious shortcomings.

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] Automatic recorder for dynamic compaction construction, including rangefinder, ground receiving device, and PC.

[0038]In the figure, a rangefinder is installed on the top of the dynamic compactor to measure the falling distance. The distance measuring instrument has a laser beam generator JG and a distance measuring system. The distance measuring system automatically tracks and monitors the lifting process of the tamper. The distance measuring system includes a laser beam generator module a (its function is to control the emission of the laser, and its principle is to The generator issues instructions to make the laser generator emit laser), the laser beam emission frequency control module b (its function is to control the frequency of laser emission), the laser beam reflection signal optical lens module c (its function is to focus the received reflected las...

Abstract

The invention relates to an automatic recording instrument for dynamic compaction construction. The automatic recording instrument comprises range finders, a ground receiving device and a PC (personal computer), wherein the range finders are arranged on the tops of dynamic compaction machines and can measure the lifting heights (namely the compaction ranges) of hammer rams, and data information of the compaction ranges is transmitted to the ground receiving device; and the ground receiving device can simultaneously receive the information of the multi-path range finders, can be subjected to man-machine interaction operation, and can store and record the data information and transfer the monitored data to a USB flash disc. The process can be implemented without connection the PC, the later analysis, judgment and printing of the data information of the USB disc are automatically finished by the PC, and the distortion of quality control, caused by human factors, can be completely eliminated. The automatic recording instrument provided by the invention realizes automatic tracking measurement and automatic storage and recording of falling distance and compaction frequency of a hammer body of each compaction point, and can not only guarantee high project construction quality, but also save manpower resources greatly.

Description

technical field [0001] The invention relates to an automatic recorder for dynamic compaction construction. Background technique [0002] The dynamic compaction construction technology in foundation reinforcement treatment originated from Europe. Because of the simple equipment, convenient operation, remarkable effect, short capital investment period and high economic benefit, this process is widely used in foundation treatment. Its principle is mainly to use the kinetic energy generated when the rammer falls to tamp the loose soil at a corresponding depth below the surface to improve the bearing capacity of the foundation. In tamping, the determination of the number of tamping at each tamping point is generally based on the average value of the ground settlement of the last two tampings reaching the set required value. In actual construction design, the number of single-point tamping is often determined based on geological conditions and empirical data. In the constructio...
