The calculated curve is basically consistent with the measured value. The theoretical calculation result shows that the settlement is 1.63m and the consolidation degree is 93.6% when the test #1 zone is 110d. Based on the measured settlement and consolidation curves, the final settlement under calculated load is 1.684m. In the first phase of the project, the Nansha Port of Guangzhou Port was constructed by dredging the land with a dredging basin and forming a land area, and then using a vacuum preloading method to reinforce the soft ground to form the site behind the quay. This successful practice satisfies the short construction period of the project and the lack of a large number of piled materials in the local area. This ensures that the project will be completed within the expected construction period and put into operation on time, thus achieving significant economic and social benefits and adapting to Guangzhou. The city’s overall development strategy has played a huge role in the rapid expansion of port facilities and provided useful experience for the promotion of vacuum preloading technology. Through the successful implementation of the project, the following two main conclusions have been obtained: (1) In the case where there is a sand-like interlayer in the middle of two soft soil layers, the plastic drainage plate penetrates the interlayer and does not affect the sealing performance of the vacuum preload. (2) For the case where the topsoil is weak and there is no intermittent drying period, certain measures shall be taken to meet the requirements of the construction load of the loader. The principle of the secondary sealing hinge is: when the construction floor is used, the hinge joints are left out. At this time, the middle floor only bears the horizontal axial force and does not receive the shear force transmitted by the side floor. Under this condition, the gate wall is calculated to satisfy the stability. The maximum height of the wall and the height of the backfill wall are required. When the gate and fill are applied to this level, the hinges are closed and the intermediate floor is subjected to force. This not only eliminates most of the differential settlement during the construction period, but also Reduces the negative bending moment of the center floor. The sluice chamber calculated the optimal height of the reaming wall to be 9.0m and the backfill of the wall was 5.0m. After the completion of construction, the differential settlement of the gate wall was basically eliminated. This process can not only eliminate the differential settlement, but also have a good effect on reducing the stress on the middle floor and improving the stress state of the floor. The sluice area environmental layout and architectural design Dongluo River ship lock is located in the Bagongshan Scenic Area. The layout of the sluice area and the architectural styling are all taken into account in coordination with the scenic environment, so no matter whether it is from the main control room of the curved surface modeling to the towering Suspension bridge bridge, or from the flower bed, wall modeling to architectural color, are all integrated with Bagui Mountain Scenic Area, adding a scenic spot for the cultural city Shouxian. In the design process of the Dongluo River lock, combined with the characteristics of the ship lock, the application of the secondary sealing and sealing technology of the rear drainage system, the cast-in-place concrete structure of the lock chamber, the floor of the lock chamber, and the steel integral track of the hoist Some researches and innovations have been made in the structure and other aspects of the beam, and good results have been achieved. It will have certain reference and promotion values ​​in the future design of ship locks of the same type.
Advantages of electric Pressure Cooker: first, safety is very important, because it feels unsafe and dangerous for pressure vessels, but the safety of electric pressure cooker is quite high. At present, most Electric Pressure Cookers on the market adopt the floating sealing structure of separating the inner pot from the pot cover. When the pressure is too high, such as overpressure, it can automatically relieve the pressure, which is the most critical. Moreover, in terms of control, pressure control, temperature control and other control technologies are adopted, which can automatically realize the control range of pressure and ensure safety. 2. It has the function of fast and automatic cooking. Because the electric pressure cooker can automatically realize the cooking procedure according to different food and different time, it does not need to be supervised, which reduces people's labor burden. 3. Energy saving because the electric pressure cooker is controlled by time and has pressure, its energy consumption is less and its efficiency is higher than other pots. It is a real energy-saving product. In addition, the electric pressure cooker has many selling points, such as fresh-keeping function, nutritional preservation function, boiling traditional Chinese medicine function and so on. Because the electric pressure cooker is in a sealed state with a certain pressure in the working process, the things are basically isolated from the external air, which avoids the oxidation of food with oxygen in the air during cooking and destroys the nutrition of food. It has the characteristics of short cooking time and no gas, and also avoids damaging various vitamins and amino acids in food. It has the function of fast and automatic cooking. Electric pressure cooker is an upgraded product of traditional pressure cooker and Electric Rice Cooker. It combines the advantages of pressure cooker and electric rice cooker, adopts new technologies and structures such as elastic pressure control, dynamic sealing, external rotating cover and displacement adjustable electric switch, fully sealed cooking and continuously adjustable pressure, and completely solves the safety problems of pressure cooker, Remove the safety hidden danger of ordinary pressure cooker that has plagued consumers for many years; Its thermal efficiency is more than 80%, saving time and electricity (more than 30% electricity saving than ordinary electric rice
