Description
Technical Field
The utility model relates to a dado device is assembled fast to combined.
Background
When the hole digging pile in the quicksand stratum is constructed, the hole is difficult to form. In the construction process, the quicksand has no cohesive force, and in addition, the underground water content is rich, the water pressure is high, the sand gushing phenomenon is serious in the excavation process, and the pore-forming speed is extremely slow. When the drift sand is seriously lost, a series of quality problems such as large-area suspended ceiling around a hole, serious waste of the concrete in the protecting wall, hole crossing and the like can be caused, even collapse can be caused, and the life safety of constructors is seriously threatened. In addition, different stratum structures and physical properties are different, special treatment is only needed to be carried out on special stratums in normal construction, and the large integral type retaining wall structure cannot meet the requirement of changeable geological conditions due to the fixity of the structure size no matter in the size of the transverse pile diameter or in the longitudinal length, so that the construction is difficult, unnecessary waste is caused, and the construction cost is increased.
Disclosure of Invention
The utility model discloses a combined fast assembling dado device, which is characterized in that the device comprises an assembling type steel bar supporting framework and a woven geotextile with a permeable outer layer and a sand-blocking outer layer; the assembled steel bar support framework comprises a plurality of sections of equal-length segmented frameworks, each segmented framework is formed by splicing a plurality of arc equal-length steel bar net pieces and transverse supporting steel bars into a ring, each segmented framework comprises more than two transverse supporting steel bars, the arc equal-length steel bar net pieces are fixed on the transverse supporting steel bars in a welding mode, connecting nuts are welded at the ends of the two ends of each transverse supporting steel bar, and the adjacent segmented frameworks are lengthened through bolts; the geotextile weaving machine is characterized in that the geotextile weaving machine is formed by weaving polypropylene and polyethylene flat wires, the length of the geotextile weaving machine is equal to the circumference of a segmented framework, the height of the geotextile weaving machine is equal to the height of the segmented framework, and the geotextile weaving machine is fixed by binding wires.
The transverse supporting steel bars are hot rolled steel bars with the diameter of 16mm, and the arc-shaped equal-length steel bar net pieces are round steel bars with the diameter of 12 mm.
The outer layer woven geotextile takes polypropylene and polyethylene flat filaments as raw materials and consists of at least two groups of parallel yarns (or flat filaments), wherein one group is called warp yarns along the longitudinal direction (the fabric advancing direction) of a weaving machine, and the other group is called weft yarns in transverse arrangement. The warp yarns and the weft yarns are interwoven together by different weaving equipment and technologies to be woven into a cloth shape, the common woven geotextile is thin, has quite strong tensile strength (longitude is larger than latitude) in the longitudinal direction and the transverse direction, and has good stability. The two are bound together by binding wires or binding belts to form a temporary retaining wall, and after the temporary retaining wall is hollowed, a reinforced concrete retaining wall is constructed on the inner side of the temporary retaining wall, so that the temporary retaining wall is applied to construction of hole digging piles in quicksand strata.
The utility model has the advantages that: the rapid wall protecting device capable of being assembled has the advantages that the inner layer steel reinforcement framework is simple to process and manufacture, high in strength, stable in structure, free of use, easy to assemble in a limited space and the like. The outer woven geotextile has a barrier function, and the geotextile is transversely placed in a channel of flowing liquid with suspended particles to prevent fine mud particles and allow the liquid to pass through. The water-sand separating device has the characteristics of high tensile strength, corrosion resistance, good filterability, good flexibility and the like, and can effectively separate water and sand. The temporary retaining wall formed by the two components has the advantages of light weight, good water and sand permeable effect, convenient operation in a limited space at the bottom of a hole, low manufacturing cost, high construction speed and the like. The temporary retaining wall has good effects in the aspects of quality safety, economic benefit, social benefit and the like.
