Problems solved by technology

This method is very primitive, and there are problems such as long preparation time, heavy weight, difficult implementation, easy water seepage, collapse, etc., and the workload of cleaning up after the flood recedes is also very large.
The biggest drawback of this method is that the reliability of flood control is low
Many basement flooded cases show that the seemingly solid pile of sandbags quickly collapsed in the face of the flood, seriously affecting the confidence and enthusiasm of all flood fighters

Embodiment 1

[0033] Such as Figure 1-2 As shown in the figure, during the later reconstruction of the entrance and exit of the underground space, pick ears 4 are left at certain intervals at the drainage ditch located in the underground space. Does not affect the drainage effect. The material of the pick ear is concrete, and steel bars are set inside it to bear the upward pull-out load. When the flood occurs, remove the grille cover above the gutter, insert the bolt 5 with the nut into the cross-shaped bottom gusset 6, and put the bottom gusset into the gutter, from the position without the pick ear Enter and move to the bottom of the pick ear, put the horizontal rod 1 into the bolt 5, adjust the position and put it into the backing plate, and fasten it with double nuts. Afterwards, the vertical bar 2, the diagonal stay bar 3 and the horizontal bar 1 are connected with bolts and fastened to form a firm triangular support device. Further, all the water retaining components are connected...

Embodiment 2

[0037] Such as Figure 3-5 As shown, when the basement is built or later transformed, a reinforced concrete beam or pier body 10 is buried at the entrance and exit of the car ramp, and a pre-embedded anchor bolt 8 is arranged in the beam or pier body 10, and the head of the pre-embedded anchor bolt 8 has threads. The anchor bolts cannot be exposed to the ground of the ramp, and are placed in the notches 11 placed in advance by the beam or pier body 10. During normal use, the anchor bolts are filled with anti-corrosion and anti-rust protection materials in the notches 11, and a cover plate 12 is arranged on the notches. Make sure that it does not affect the normal use of the ramp.

[0038] When rainstorm comes, when needing to keep water, open the cover plate 12 of notch 11, utilize spanner to screw the pre-embedded anchor bolt 8 in the notch with lengthened anchor bolt 9, and fasten. Insert the horizontal rod 1 into the extended anchor bolt 9, adjust the position and insert i...

Abstract

The invention discloses an assembled flood control component, which belongs to the technical field of engineering rescue and provides a standardized and assembled flood control component. Industrial production and assembly are realized, and the prefabricated component utilizes the unique structure of the underground space, and can be quickly installed at the entrance and exit of the underground space. It can be used when a flood occurs, which overcomes the shortcomings of conventional flood control equipment such as complicated structure and inconvenient installation. The flood control component can still be quickly assembled in the case of a power outage caused by a flood, which greatly improves the safety and reliability of flood control.

Description

technical field [0001] The invention relates to the field of flood control and disaster mitigation, in particular to an assembled flood control component. Background technique [0002] As the global climate warms, the probability of severe weather is getting higher and higher. Many areas experience extremely heavy rainfall. The rainfall intensity far exceeds the flood drainage capacity of the city, causing rainwater to accumulate on the surface and form waterlogging. The basement of the building can be used as a shopping mall, supermarket, parking lot and equipment room. The indoor ground is much lower than the outdoor ground, and it is connected with the outside world through car ramps, bicycle ramps and stairs. Flood water often flows into the basement through these openings, submerging Its internal facilities and equipment cause huge property losses, and sometimes even bring life danger. [0003] The existing basement flood prevention method is to pile up sandbags at the...
