中文Wuhan, the central city in central China, a new landmark of Hero City, an important industrial base, geoscience and education base in the country, and one of the largest integrated water, land and air transportation hubs in the inland, connecting east to west and connecting south to north The National Geographic Center is known as the "heart" of China's economic geography.
As the first five-year plan after starting the new journey of building a socialist modernized country in an all-round way, the state promulgated the outline of the fourteenth five-year plan clearly "named" Wuhan: it proposed to focus on the national central city, the core city of the Yangtze River Economic Belt and the international To transform the overall positioning of a metropolis, accelerate the construction of a national economic center, a national scientific and technological innovation center, and a regional financial center, and strive to build a modern Wuhan. In such a top-level design related to the future development of the country, Wuhan was directly named, showing that the country has high hopes for the development of Wuhan during the "14th Five-Year Plan".
SEMW MS45E double-wheel mixing drilling rig does not want to miss the city's perfect performance in the 14th Five-Year Strategy. It has joined Wuhan's thriving urban construction with full enthusiasm and unique charm.
Walking into the construction site of the Sitai Village project in Wuhan, the MS45E double-wheel mixing drilling rig stands majestically, looking up at the roaring rhythm of the engine, busy in an orderly manner. This is the first MS45E double-wheel mixing drilling rig in Wuhan. Since May last year, the equipment has been continuously deployed in many construction sites in Wuhan, and the market reputation and user evaluation have been upgraded again. With its strong product strength, the MS45E double-wheel mixing rig soon became a local The famous "star".
The first stop of continuous combat construction:Wuhan Yongqing Film Comprehensive Development Project
In March 2021, the project is located in the north of the intersection of Yanjiang Avenue and Huangpu Street, Yongqing Street, Jiang'an District, Wuhan City. It is the main urban area of Wuhan City and has convenient transportation. The proposed construction of the project includes multiple super high-rise buildings, small high-rise buildings and multiple overall pure basements.The main task of the equipment is to make nearly 100 underground cement-soil mixing and water-stop wall (CSM) mixing piles with a thickness of 800mm, which are inserted into the strongly weathered rock formation. The difficulty of the project lies in the complex ground conditions of the project site, and the hardness and thickness of the sand layer are relatively high. Large, the clay viscosity is strong, it is not easy to be stirred into piles, and the construction has a certain degree of difficulty.
The second stop of continuous combat construction:Wuhan Sitai Village also builds house B plot foundation pit support project
In October 2021, the project site is located at the intersection of Sitaitai Road and Sitai 3rd Road, Hanyang District, Wuhan City. The excavation depth of the foundation pit is 3.3m-8.3m, the area is about 13323㎡, and the circumference is 485m. There are 36 continuous wall (CSM) mixing piles with a wall thickness of 800mm, which are inserted into the strong weathered rock layer. Each pile takes 3.5 hours. The construction requires that the main machine should be stable and flat, the allowable deviation of the verticality of the pile frame is 1/250, and the stepping distance should not be greater than 50mm, the difficulty is that the surrounding environment of the foundation pit is relatively complex. The north and east sides of the foundation pit are the existing roads and houses to be demolished, and the west side is the Hanjiang River. influence of the surrounding environment.
The third stop of continuous combat construction:Wuhan Sitai Village also builds the foundation pit support project of block A
In January 2022, the project is located at Sitai 3rd Road, Hanyang District, Wuhan City, 300m away from the foundation pit support project site of Block B, the excavation depth of the foundation pit is 3.6m-11.45m, the area is about 19600㎡, and the circumference is 625m , The project is to make more than 100 mixing piles for underground cement-soil mixing water-stop continuous wall (CSM) of equal thickness. At present, more than 20 piles have been made, with a wall thickness of 800mm, which is inserted into the strong weathered rock layer. Each pile takes 3.5 hours. The construction requires piles The confining compressive strength is not less than 1.0MPa, and the deviation of the verticality is not more than 1/300. The difficulty of the project lies in: there are many underground obstacles, and the surrounding pipelines are complicated. The equipment can control the amount of cement slurry and drilling speed during the construction process through real-time detection. And precision, to ensure the mixing effect, was highly praised by the construction party.
In various quagmire construction sites, SEMW MS45E double-wheel mixing drilling rig danced with the "foundation", and drilled and drilled through the blockage, difficulty and pain points of pile foundation construction with high quality, so as to put the project into rapid construction as soon as possible. Resist" and "strengthen".
Responsibility and responsibility coexist, quality and innovation coexist, SEMW produces every product with ingenuity, and serves every customer with caring. SEMW Machinery has always been committed to providing customers with overall solutions for underground infrastructure, helping the construction of national urban infrastructure, To fully meet the construction needs of customers, SEMW Machinery will always be on the way!
Product introduction of MS45E double-wheel mixing drilling rig (CSM method): CSM method is also called milling deep mixing method. Combined with hydraulic groove milling machine & deep mixing technology, it is an innovative construction method of underground diaphragm wall. The CSM construction method is mainly carried out with MS45E double-wheel mixing drilling rig. It is mainly used for water-stop curtains and retaining walls in deep foundation projects such as building foundation pits, underground parking lots, subway stations, underground commercial streets, reservoir dams, and environmental protection projects. construction.
Product innovation:
■Adopt mature JB series pile frame and square drill pipe guide to ensure construction accuracy;
■Real-time detection and control of cement slurry volume, drilling speed and precision during construction to ensure mixing effect;
