Background
The foundation pit engineering mainly comprises foundation pit supporting system design and construction and earthwork excavation, and is a system engineering with strong comprehensiveness. It requires close cooperation between geotechnical engineering and structural engineering technicians. The foundation pit supporting system is a temporary structure and is not needed after the construction of underground engineering is finished. The foundation pit and the foundation trench are used for building the foundation of the building, and are different in plane shape. The foundation pit is square or relatively close to square, and the foundation pit is in a long strip shape and sometimes is relatively long. What you want to grasp is the difference in their shapes. The foundation pit is characterized in that the base area is within 27 square meters (not 20), and the long side of the base is less than three times of the short side. The base groove is the base groove with the groove bottom width within 3 meters and the groove length more than 3 times of the groove width. That is, the deep foundation pit is generally defined as: the bottom area is within 27 square meters (not 20), the long side of the bottom is less than three times of the short side, the excavation depth exceeds 5 meters (including 5 meters) or more than three layers (including three layers) of the basement, or the depth does not exceed 5 meters, but the geological conditions, the surrounding environment and underground pipelines are particularly complicated. When the deep foundation pit sewage pipeline is constructed, as the foundation pit is deep, the process is complex when steel sheet piles are adopted for construction, the construction is limited by the site, the operation is inconvenient, the cost is greatly increased, and the construction is inconvenient, so that a portable assembly type turnover deep foundation pit steel plate box supporting structure is provided.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a deep basal pit steel sheet case supporting construction can have enough to meet need of handy assembled, includes the steel sheet block, the quantity of steel sheet block is four, four the steel sheet block includes channel-section steel, steel sheet, the equal welded steel sheet in upper and lower both sides of channel-section steel, the upper surface screw thread of steel sheet has cup jointed fixing bolt, the bracing post has been cup jointed in one side activity of steel sheet, fixing bolt has been cup jointed to the equal screw thread in both sides of bracing post, fixing bolt's one end screw thread cup joints to the inside of steel sheet.
Further, the channel steel is the channel steel with the diameter of 28# b.
Further, the steel plate is a 12mm thick steel plate.
Furthermore, the bracing column adopts the channel steel with the diameter of 28# b, the diameter of the bracing column is five meters at a point and the distance between the braces is 12 cm.
Optionally, the fixing bolt is an M20 bolt.
Has the advantages that:
1. this deep basal pit steel sheet case supporting construction can be had enough to meet need to handy assembled, use through the cooperation of channel-section steel and steel sheet, utilize welding technique to weld channel-section steel and steel sheet and form the steel deck, the cooperation of utilizing fixing bolt and bracing post is used simultaneously, utilize the bracing post to connect the steel sheet, fix through fixing bolt simultaneously, and then install between the steel deck, make this deep basal pit steel sheet case supporting construction can have had enough to meet need to handy assembled out the steel sheet case of co-altitude according to the foundation ditch degree of depth, utilize this steel sheet case temporary support, and then guarantee excavation safety, the effectual problem of excavation difficulty of deeper excavation supporting of having solved. And use fixing bolt to fix and guarantee that the steel sheet case dismantles conveniently, but cyclic utilization, great saving cost has improved this handy assembled deep basal pit steel sheet case supporting construction's that can have enough to meet need practicality.
