Abstract.Water supply and drainage pipeline is an important part of municipal engineering. It is necessary to ensure the rationality of pipeline design and improve the technical level of pipeline design. Taking the first phase of Wisdom Express Road, Second Ring West Road, Hangzhou Asian Games supporting project as an example, the application of BIM Technology in municipal water supply and drainage pipeline design is analyzed from the aspects of model construction, three-dimensional design, collision detection, pipeline planning, etc. the BIM model is constructed and the modeling analysis method is … Read more →

Abstract.Under the bill of quantities pricing model, the price of the contract is determined in advance, making the focus of enterprise project cost management be to control the expenditure of construction costs on the premise of established revenue, reduce the risks brought about by the bill of quantities pricing model, strengthen cost control, give play to the advantages of strategic cost management, and ultimately minimize project risks to maximize the benefits obtained by the enterprise. This paper mainly analyzes the problems existing in the cost control and cost management process of construction … Read more →

Abstract.Laser cladding technology is an advanced surface modification technology that can achieve the coating, repair, and manufacturing of surfaces of metals, alloys, ceramics, and other materials. Laser cladding technology has the advantages of high efficiency, high accuracy, and the ability to achieve multi material composites, and is widely used in automotive, aerospace, shipbuilding, medical and other fields. However, there are also some problems with laser cladding technology, such as unstable weld pool morphology, uneven weld pool depth, and thermal stress, which limit its application range and … Read more →

Abstract.At present, the rapid development of municipal traffic engineering is in line with the high quality development trend and the demand for accurate management. The municipal traffic builders strictly control the quality from the aspects of planning and design, construction management, material testing, measurement and acceptance, among which material testing is an important part. The quality of engineering construction materials directly determines the final quality of engineering construction, so the layout and planning of material control must be done well in the actual implementation process. … Read more →

Abstract.This paper designs an automatic obstacle avoidance robot based on artificial intelligence detection and recognition, including a shell, and a detection and obstacle avoidance mechanism is set inside the shell; the detection and obstacle avoidance mechanism includes a movable member, a screw, a first electric actuator, a first camera, a gear, a rack and a steering assembly; by setting the detection and obstacle avoidance mechanism, the first camera and the second camera can take pictures of the surrounding environment during the movement of the shell, and when the micro When the computer … Read more →

Abstract.The precise positioning of the firing explosion point is an effective means to test the technical performance of artillery weapons and equipment warfare, but when the CCD single pole distance method is directly used to detect the explosion point, it is often affected by the obstacles in the shooting visual area, terrain and landform, and the detection and positioning accuracy is difficult to meet the evaluation requirements. To this end, the double CCD intersection method is first used to locate the explosive point, and the target recognition and positioning algorithm is used to realize the … Read more →
