It is suitable for the surface roughness measurement of all kinds of precast components.

Portable intelligent supplementary grouting instrument ， schematic diagram of portable intelligent supplementary grouting instrument of enterprise construction method ， grouting material loading ， automatic continuous supplementary grouting 04 honed and studied, committed to solving practical problems, and Shanghai Jianke took the lead in systematically developing embedded sensor method, borehole endoscope method, X-ray digital imaging method Four sleeve grouting plumpness detection methods of embedded steel wire drawing method can meet the requirements of sleeve grouting plumpness detection in actual project construction, acceptance stage and use stage; The significant influence of various sleeve grouting defects on the mechanical performance of sleeve joint, precast components and overall structure is studied, and the drilling injection supplementary grouting technology and supporting construction method are put forward.

At the same time, the superimposed surface roughness detector has a visual operation interface, high detection accuracy, low cost, high efficiency and easy portability.

The instrument has the obvious advantages of automatic and intelligent supplementary grouting process, small diameter, small flow rate and small grouting volume, adjustable grouting speed, detachable material pipe, portability and lightweight.

The instrument software system is developed based on PCL and QT.

In order to strengthen the research on the application scenarios of digital technology in advantageous businesses and improve the digital level of traditional technology, Shanghai Jianke has developed intelligent detection and treatment equipment for precast concrete structures: overlapping surface roughness detector, digital ultrasonic imaging detector and portable intelligent filling instrument.

The instrument can select different types of ultrasonic probes, which is not only suitable for the internal quality evaluation of concrete structure, reinforced concrete structure and steel structure, but also suitable for the detection of internal defects and compactness of joints at the bottom of shear wall.

01 high precision detection: the overlapping surface roughness detector is jointly developed by the overlapping surface roughness detector and Tongji University.

The 3D laser scanner or depth camera is used to collect the point cloud data of the composite surface of precast components, the RANSAC algorithm is used to segment the point cloud data, and the plane fitting of the segmented point cloud data is carried out based on the eigenvalue method, The datum plane equation is established to calculate the roughness value and roughness evaluation index value from the superimposed surface to the datum plane.

The digital ultrasonic imaging detector adopts the method of one sending and one receiving to collect ultrasonic signals at different measuring points, and carries out real-time identification of internal defects of the structure through B-scan imaging map, which can realize quantitative identification of defect size, and display the detection results immediately and intuitively.

Based on pre prevention, in-process detection and control, and post detection and rectification, Shanghai construction technology has also established a complete set of engineering oriented sleeve grouting quality overall control technical system, and the relevant research results have been standardized, promulgated and implemented.

It can intelligently calculate the roughness value of components.

The comprehensive use of management means, construction measures and detection technology, combined with the above intelligent equipment for detection and treatment of precast concrete structures, can effectively control the construction quality of key parts and ensure the safety of the project in the whole process…

Shanghai Jianke adheres to the two-way drive of “specialty” and “wisdom”, and uses technologies such as digitization, networking and intelligence to provide information technology and application solutions suitable for multi-level construction, management and operation of projects, parks and cities.

The mechanical performance can reach the defect free level after supplementary grouting.
