  -- Comprehensive treatment project of Xiaoluo area from mixigou to Siqiao of Yangtze River in Wanzhou District, Chongqing,China   Recently, the water conservancy and municipal construction project of Wanzhou Yangtze River four bridge water level fluctuating zone is being promoted comprehensively,the project includes embankment expansion, landslide treatment, road construction, landscape greening, etc. During the renovation construction of 3707 meters long embankment expansion, the soft foundation treatment was carried out in the soft soil section with an area of 120000 square meters. Vibroflotation Stone Column technique be used to treat soft foundation is the control engineering in the whole project. The stone column piles with average spacing of 1.5m, diameter of 1m and depth of 5-30m can effectively improve the bearing capacity of foundation and lay a solid foundation for the construction of embankment. Due to the large construction volume and complex construction environment, the construction party takes effective measures to ensure the construction quality and progress. In view of the sliding problem of vibroflotation construction platform, the method of riprap foot protection and pressing foot is adopted to stabilize the construction platform. The mud pump and mud pipe are used to pump the mud produced by vibroflotation into the mud pit, effectively prevent the mud from flowing out, and at the same time, the mud is centrally treated to meet the requirements of environmental protection.  

  This vibro-replacement stone column construction is carrying out by BVEM. The measured buried depth of the stable groundwater level in the engineering area is 2.00 ~ 5.90m. After testing, the environmental water has sulfate type weak corrosivity to concrete. The whole geology is Sandy. The lithology of the stratum is mainly sandy loam and sand. Bottom layer is four layers of medium fine sand liquefaction layer. The foundation treatment depth is required to be within 1m below the bottom of liquefaction layer. The project adopts equilateral triangle pile arrangement, with pile diameter of 0.8m, pile depth of 15m, sheet pile spacing at the bottom of rubber dam of 2.5m, and retaining wall pile spacing on both banks of 2.0m. The filling amount per linear meter of pile body shall not be less than 0.7m3, and the construction period of vibro replacement stone column is 38500m, with a total construction period of 30 days. At present, six units of BVEM 75kW vibroflot devices are working in this project at the same time.     

Recently, Beijing Vibroflotation Engineering Machinery Limited Company(BVEM) and OVERSEAS CAMBODIAN INVESTMENT CORPORATION LTD (OCIC) cooperated in the project of vibroflotation sand compaction of Cambodian gold and silver island, and received good news of successful pile test.     The project adopts BVEM 's high-power equipment-180kW vibroflotation device, and the pile test carried out from October 1, 2020. From the equipment mobilization and assembly to the vibroflotation construction, our technical personnel track the whole process of service.Equipment engineers teach local workers to assemble and explain the precautions in detail.According to the geological conditions, the technical engineers timely adjusted the construction parameters and optimized the process. To ensure original recorded data are true and concise, and the scheme is simple and easy to implement.In order to reduce environmental pollution, our technical personnel also proposed to adopt the water and gas linkage mode, which accelerated the construction progress and reduced the sewage discharge.   According to the inspection of Cambodia's third-party inspection organization, the site elevation was measured before and after the construction. The ground in the test pile area dropped by 60cm which shown vibro compaction effect was good. The number of standard penetration tests before and after the construction is obviously increased, which fully meet the design requirements.   During the construction period, Lord Fang Qiaosheng,the director of OVERSEAS CAMBODIAN INVESTMENT CORPORATION LTD (OCIC), visited the island for many times and expressed his approval for the construction effect. They immediately signed the equipment sales and service cooperation contract with our company, and invited our personnel to inspect the highway project of new airport in Phnom Penh.   The planned artificial island area of gold and silver island is to execute 129 hectares. Due to the rainy season, project still in the reclamation stage, the vibroflotation construction on the island is in order.BVEM will closely track the progress of this project and continue to provide good technical services. At the same time, we should pay attention to the highway project from Phnom Penh to the new airport invested by OCIC, and contribute to the vibroflotation engineering of friendly country.     

Tibet is located in the southwest of China's Qinghai Tibet Plateau, with an average altitude of more than 4000 m, known as the roof of the world. Its severe geological conditions also create a unique landscape in Tibet. Its unique geological condition of mixing round gravel with coarse and fine sand also makes the traditional vibroflotation equipment unable to cope with it. In order to adapt to the complex geological conditions in Tibet, our company has tested different power construction equipment (including 75kW, 130kW, 150KW, 180kW) for many times, and found that the small-power vibroflotation equipment can not meet the construction requirements. Therefore, our company spent a lot of manpower and material resources to develop high-power vibroflotation equipment (200kW, 260kw, etc.) to meet the complex geological requirements of Tibet. In mid-019, BVEM officially launched the vibro replacement gravel pile project in Zedang Avenue commercial and residential buildings in many places in Tibet (including Shannan City, Lhasa city and Xigaze city). The Vibroflotation team has overcome the harsh environmental and geological conditions in Tibet, fully guaranteed the project quality and worker safety, and successfully completed the project. Among them, the proposed hada happy garden in Shigatse City mainly includes 58 buildings with one basement floor. The proposed building is planned to adopt frame and frame shear structure, and raft and independent foundation are proposed as the foundation form. The engineering importance grade is grade II. Due to the low bearing capacity of foundation soil and liquefaction of foundation soil, it can not meet the bearing capacity and seismic requirements of the proposed construction site, so it is necessary to carry out vibro replacement reinforcement for the foundation soil. During the construction period, under the sincere cooperation of various departments, our company ensured the normal operation of the equipment, completed the construction task on time and with quality, and was highly praised by Client.                 

   Recently, the construction of three shiplocks in the sub center of Beijing has started, and the foundation of the project is reinforced by vibro replacement stone column. As a local enterprise in Beijing, Beijing Vibroflotation Engineering Machinery Co., Ltd. has the honor to contribute to urban construction by undertaking the foundation treatment works of this project. In the construction of vibro replacement gravel pile, the filled crushed stone is vibrated and compacted section by section under the combined action of high-frequency vibration of vibroflotation device and high-pressure water flow. In this way, the filling and vibrating compaction are carried out until the ground, so as to form a dense gravel pile in the foundation and achieve the effect of soft foundation reinforcement. In the next two weeks, nearly 4000 vibro replacement gravel piles will be driven in the foundation pit of more than 10000 square meters to fully improve the bearing capacity of the foundation.     "At present, the project is under construction for the 104 m section of the main structure of the ship lock. The foundation treatment of the whole lock chamber structure will be completed by the end of this month, and the bottom plate of the ship lock will be completed by the end of this year, and the navigation conditions will be available in June next year." According to reports, Yulinzhuang shiplock will take on the water running channel between Gantang lock and Yangwa lock, so that ships can overcome the water head difference between upstream and downstream of the river lock, and safely, stably and quickly cross the lock. "
