The utility model provides a system is strutted to bottom plate template, it can satisfy special hydrology area's requirement, has reduced the construction accident for whole construction is safer, and the efficiency of construction is higher.
Description
Technical Field
The utility model relates to a construction technical field, in particular to system is strutted to bottom plate template.
Background
The erection height is 8m or more according to the regulation of a safety management method; setting up a span of 18m or more and a total construction load of 15kN/m2 or more; concentrating line loads of 20kN/m2 and above, expert organizations should demonstrate the special scheme. The total load of the concrete supporting engineering construction of the main structure of the bead triangle certain loop GFHD-2 standard DSK42+ 849-DSK 43+670 open trench tunnel is more than 15KN/m2, and the method belongs to the project range of partial projects with large risks exceeding a certain scale. The open-cut tunnel is positioned on the north side of the Taihe station, is a first section of open-cut tunnel after the station, has the total length of 821m in the construction section of the tunnel, and consists of 2 sections of a main line of an open-cut section and a 26# working well; the main structure is an underground single-layer frame structure, open excavation construction is adopted, the height of the main structure of the standard section is 8.865m (without a cushion layer), the width is 13.10m, and the embedding depth of the top plate is 0-8.1 m. The main structure and the auxiliary structure of the tunnel are constructed by adopting an open excavation method.
The geology of the interval section mainly comprises a fourth system of artificial filling, alluvial silty clay, completely weathered and strongly weathered siltstone and carbonaceous slate. The underground water mainly takes fourth-series pore water and karst fracture water as main materials, pore diving mainly occurs in a filling layer and a sand layer, the water quantity is rich, the hydraulic connection is smooth, and the pressure bearing performance is realized; karst fissure water is stored in karst cracks and karst caves in limestone development, the water quantity is greatly changed under the influence of the development degree and the connectivity of karst, the karst fissure water has pressure bearing property, surface water and concrete structures of underground water teams have weak corrosivity, and the karst fissure water has micro corrosivity on reinforcing steel bars in reinforced concrete structures. The fracture structure passes through, the fracture structure is mainly wide fracture, and water gushing, mud outburst and the like are easy to occur in the fault structure section to cause adverse effects on construction. The limestone section belongs to a covering karst area, the karst belongs to a strong development area, besides karst cave development, a large amount of flood flushing accumulated objects are distributed, overlying strata are mostly clay, silty clay, coarse gravel, round gravel soil and the like, the overlying strata are mostly soft plastic-shaped clay or silty clay in contact with a bedrock surface, because the underground water level is higher, the fourth series of strata are influenced by underground water more, the strength is lower, ground subsidence is easily caused in the construction process, and the karst is complicated and uncertain in space development.
In view of the above, it is desirable to provide a formwork support system for tunnel construction that is compatible with the above-mentioned hydrological features, and the suspension of the floor formwork is of central importance.
SUMMERY OF THE UTILITY MODEL
