Deep foundation pit supporting construction unit -- Shanghai Qiangqiang Foundation Engineering Co., LTD

Shanghai Qiangqiang Foundation Engineering Co., LTD., the construction unit of deep foundation pit support, has been involved in many engineering projects due to the increasing number of high-rise buildings and super high-rise buildings, the increasing use of underground space and the increasing depth of foundation pit excavation. As the soil pressure increases with the increase of depth, the excavation deformation often occurs in the construction of deep foundation pit, which is difficult to ensure the construction quality. Shanghai Qiangqiang Foundation Engineering Co., LTD. 's patent technology -- prestressed fish-belly type foundation pit steel support technology solves this problem well.

Classification of reverse method in foundation pit engineering

Classification of reverse practice in foundation pit engineering:1Full reverse approach The floor of each layer of the underground structure is used to form a horizontal support for the surrounding ground wall, and then the earth is excavated under it, and the building materials are excavated and transported into the cavity reserved on the floor. 2Partial reverse method (conjunctive method) In engineering practice, according to different requirements, we can adopt the main building first as skirt building and then reverse, skirt building first as main building and then reverse, center as peripheral reverse and so on, which become partial reverse.

Deep foundation pit supporting scheme commonly used by deep foundation pit construction and supporting units

Deep foundation pit supporting construction units should achieve fine management, no matter excavating soil, retaining soil, enclosure, precipitation and other construction links may lead to major safety accidents, especially the collection, sorting and analysis of geological survey reports and monitoring data, need to be seriously implemented to ensure the safe and orderly operation of the project construction.

Basic concept of foundation pit supporting system

In the case that the engineering site is open, there are no buildings around, and the foundation pit is not deep, the slope excavation can be carried out in the foundation pit support engineering, that is, no support excavation, this method is economic and simple. In general, the urban center is often densely built and does not have the condition of slope excavation, so it is necessary to construct the foundation pit supporting structure first, and then excavate under the protection of the supporting structure. The deep foundation pit has the problem of excessive soil pressure, so it is necessary to adopt the foundation pit supporting system.

Qualification requirements for foundation pit supporting construction units

Foundation pit supporting construction units can be divided into Grade 1, Grade 2 and Grade 3 of foundation engineering professional contracting qualification. According to the Construction enterprise qualification standards formulated by the relevant departments of the Construction Law of the People's Republic of China, the professional contracting qualification of foundation and foundation engineering in the new standards implemented on January 1, 2015 has been changed to the professional contracting qualification of foundation and foundation engineering.

Marine foundation treatment method

How to do the sea foundation treatment method? The ground treatment on land in order to lay the foundation in the soft soil, for the thick soft soil is usually used pile machine structure, lay a few piles as reinforcement in the soil layer; For shallow soil, the replacement method is used to excavate the soft soil and fill with solid material. In order to effectively solve the construction and maintenance problems of soft subsoil, it is necessary to use deep cement mixing vessel (DCM vessel).
