Foundation pit supporting construction unit, foundation pit supporting plays the role of retaining soil, stabilizing the bottom of the pit and intercepting water in the engineering construction, ensuring the safety of the surrounding environment and the safety of the engineering construction. In order to ensure the construction safety of structural engineering and the safety of the surrounding environment, it is necessary to rely on the foundation pit support to control the soil surface. Its main function is to fix and ensure the stability of the bottom of the pit by blocking water flow, soil resistance and other ways. The retaining structure of foundation pit plays the role of temporary retaining structure during construction.
Foundation pit supporting construction unit-Shanghai Strong foundation In most provinces and cities in China with more than 1000 project experience.
Foundation pit support plays a role in retaining soil, stabilizing the bottom of the pit and cutting off water in engineering construction, so as to ensure the safety of surrounding environment and engineering construction.
In order to ensure the construction safety of structural engineering and the safety of surrounding environment, it is necessary to rely on foundation pit retaining to control soil deformation. Its main function is to fix and ensure the stability of the bottom of the pit by blocking water flow, soil resistance and other ways. The retaining structure of foundation pit plays the role of temporary retaining structure during construction. The calculation, construction and selection of this structure are very critical. It has a great impact on the safety, economic benefits and construction period of the construction. It is one of the key technologies of construction. Once there is a mistake, it will often cause significant losses.
The groundwater in the coastal area is very rich and the engineering geology premise is complex, so the water stop method of foundation pit supporting structure is very demanding. Once the supporting structure presents water leakage and sand gushing, it will not only affect the basement construction, but also increase the deformation of the foundation pit supporting structure, damage the surrounding situation, stimulate the surrounding pipeline deformation and damage, road settlement collapse, building tilt and other disasters, the risk is very great. Because coastal region soil spread unevenly, strong regional, in the pit water stop curtain design must also disposal was carried out on the engineering characteristics in detail, and once the attack is leaking in the construction should take emergency measures, prevent leaking chung sand to support itself and surrounding formation damage and no other can bring about unexpected loss.
Pile supporting is to dig holes, drilling (punching) reinforced concrete bored piles column type partition installed, and at the top of the pile casting large cross section between pile caps of reinforced concrete beam to increase the reliable continued, in the column type partition installed into there is a net distance between piles white-out form and tangent between piles embedded slot form close.
Soil-cement pile wall is usually placed in lattice structure, and it is important to rely on its own weight and stiffness to protect the safety of foundation pit soil wall. Generally, there is no support, and in special cases, some support can be added after taking measures. Soil-cement pile wall can be divided into deep mixing soil-cement pile wall and high-pressure rotary jet grouting pile wall.
Underground continuous wall is slurry-supported premise, along the deep excavation engineering around the axis adopt a chamfer machine digging out a narrow deep groove, after the qing tank, sling the reinforcing cage in the trough, then pouring underwater concrete with conduit method to form a unit slot, eventually in underground pouring into a continuous reinforced concrete walls.
Steel support technology for prestressed fish-belly foundation pit,It's based on the principle of prestress,Aiming at the deficiency of traditional concrete inner bracing and steel bracing on the deformation control ability of foundation pit , Through a large number of engineering research and practical application,A kind of inner supporting structure system of deep foundation pit is developed,It is composed of vertical retaining wall, prestressed fish belly beam, prepressed jacking device, enclosing purlin, Angle brace (opposite brace), calf leg, triangular connector, vertical column, etc., and is connected by high-strength bolts The plane prestressed support system and three-dimensional support structure system are safe and reliable.
