If the indoor drainage pipe is blocked and the drainage is not smooth, sewage and pollutants will enter the room and endanger human health. If the pipeline is blocked as a result, a certain intensity of water pressure may be brought, which may cause pipeline leakage. In this article, we will analyze and explain the quality problems that often occur during the construction process due to the blockage of the internal drainage pipe, and propose appropriate methods and solutions to improve the quality of the project.

The civil engineering construction is a very complicated production activities. In the whole construction process need to consume a large amount of manpower, consume a large amount of materials, use a lot of equipment, also need to deal with complex technical problems a lot. So this is for the civil engineering construction project management have strict requirements. This paper from the quality control, schedule control, cost control three aspects of the civil engineering construction project management analysis. Quality control Construction quality is the foundation of project management work, is the basic requirement of the construction of the project. Have important influence on the quality of the whole construction quality of engineering quality control. Because the civil engineering construction comprises a plurality of procedures, quality control is usually divided in time for the preparation of construction quality control, the quality control of construction process and quality control of completion and acceptance of three stages. Preparation of construction quality control of the main content is: each enterprise carefully check to participate in the project entity construction qualification, including professional subcontracting subcontracting, materialsand material suppliers; according to the basic principles of quality management, review project quality plan, quality requirements, implementationplan, including examination, treatment and other sectors to establish quality control preliminary scheme;, once appear quality problem, can quickly take thepreliminary scheme, guarantee the quality of the whole project.

Winter construction in seasonally frozen soil areas is inevitable. The variation of ambient temperature causes the freeze-thaw of the filling soils and its impact is significant, and whether the countermeasures can be effectively established and adopted is particularly important for the management and control of the construction quality of the project. This paper conducts systematic research based on the winter construction process of the dam core wall of the Lianghekou Hydropower Station, which is the third highest earth-core rockfill dam in the world under construction. The results show that for the construction site in the seasonally frozen soil area, there is a development process of the short-term frozen soils for the filling soils under the environment with low temperature in winter. The soil underwent a high-frequency freeze-thaw process wherein it was frozen at night and completely thawed during the day. During the freezing process, a large number of thin-layered segregated ice developed inside the soil to form a thin-layered or integral cryostructure, which will have an adverse effect on the engineering properties and the quality of the filling soils. And, the field tests demonstrate that the filling compaction degree of the frozen soils is difficult to meet the designed requirements. In order to effectively cope with the adverse effect of the freeze-thaw on the construction quality during the construction process, based on the analysis of the freeze-thaw characteristics of soils and its influence, and the energy exchange process of soils on-site, the principles and methods for establishing the freeze prevention system during the winter construction process are established, and a comprehensive monitoring system suitable for on-site is established in this paper. This research will provide an important reference for the scientific management and efficiency improvement of the winter construction process of the dams in cold regions.

The compaction quality of the subgrade is directly related to the service life of the road. Effective control of the subgrade construction process is the key to ensuring the compaction quality of the subgrade. Therefore, real-time, comprehensive, rapid and accurate prediction of construction compaction quality through informatization detection method is an important guarantee for speeding up construction progress and ensuring subgrade compaction quality. Based on the function of the system, this paper puts forward the principle of system development and the development mode used in system development, and displays the development system in real-time to achieve the whole process control of subgrade construction quality.

Shaft Alignment

Propulsion shaft alignment is a necessary and crucial step in the ship construction process, with manning and schedule constraints requiring accurate results as efficiently as possible. There are two methods for measuring the bearing loading along the shaft line: strain gages and load cells. The legacy method for using strain gages required a lot of man power and the legacy method for using load cells was dependent on the quality of machinist made available. Strain gages are the transducers of choice for measurement; however the data acquisition, especially for ships with long shafting systems, can require many strain gage positions and personnel to conduct tests. Load cells are used to validate the accuracy of the strain gage method and to calculate the shaft runout at each bearing location.

Chip seal is most frequently used as preventive maintenance (PM) treatments on asphalt pavement. However, it’s difficult to make the performance test of chip seal in laboratory. In this paper, the specimen molding method of chip seal is established in laboratory. Firstly, considering the structure and technique condition of the original pavement, a cushion layer of asphalt concrete (AC) is used as under layer of the specimen. Secondly, the construction process of chip seal is simulated in laboratory, which includes spraying emulsified asphalt and/or glass fiber, spreading aggregate, initial rolling and conservation, post-stage rolling and conservation in interval for some time. Lastly, visual inspection and sand patch test are used to evaluate the quality of the specimen. Research results show that the method of specimen molding and test in laboratory could relatively accurately simulate, evaluate and forecast the performance of the chip seal.
