Embodiment
[0030] like Figure 1 to Figure 5 As shown, a new type of steel formwork support device for water stabilization construction includes a steel formwork 10 installed on the water stabilization sub-base, and a support member 80 fixed on the ground is rotatably installed on the outside of the steel formwork 10, and the support member 80 passes through the anchor bolt. It is fixedly installed on the ground. An anti-leakage structure is installed on the bottom of the outer side of the steel formwork 10. The anti-leakage structure includes a fixed body 20 installed at the bottom of the steel formwork 10. The top of the fixed body 20 is installed with a connecting hook 23. The bottom of the steel formwork 10 is provided with a connecting groove 11 that is adapted to the connecting hook head 23, and the side walls of the opening of the connecting groove 11 are gradually tightened inwardly. A threaded joint 24 is installed, and the two threaded joints 24 are connected by a threaded slee...

The invention discloses a novel water-stable construction steel formwork supporting device and a construction method.The novel water-stable construction steel formwork supporting device comprises a steel formwork installed on a water-stable subbase layer, an anti-seepage structure is installed at the bottom of the outer side of the steel formwork and comprises a first fixing body installed at the bottom of the steel formwork, and a second fixing body is installed on the first fixing body through an elastic guide column; an anchoring body which freely penetrates through the second fixing body is installed on the first fixing body, and a pushing structure is installed between the first fixing body and the second fixing body. Through a first fixing body, a second fixing body and a pushing structure, under the effect that the anchoring depth of an anchoring body is gradually increased, a pressure applying block is driven to move towards the outer side, and the pressure applying block is in sealed contact with a groove or the side portion of a lower water stable layer, so that the water stable layer at the bottom of the steel formwork and exceeding the height of the pushing structure is extruded and compacted; and meanwhile, the bottom anti-seepage effect can be effectively guaranteed, and the stability of the construction structure of the cement-stabilized base layer is improved.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to a novel water-stabilized construction steel formwork support device and a construction method. Background technique [0002] With the progress of society and the accelerating pace of life, along with the popularization of automobiles and the substantial increase in the number of automobiles, the mileage of expressways and first-class highways has been greatly increased year by year, and the reconstruction, expansion and new construction of urban expressways and urban arterial roads has been strengthened. Increasing year by year, the smooth, solid and durable asphalt concrete pavement provides convenient conditions for vehicle traffic. The construction of the water stabilization base has the characteristics of long construction mileage, fast construction speed, and high flatness requirements. With the continuous progress of science and technology, the environmental...
