Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, and in particular to a quick-assembly, reusable soil waterproof baffle support structure for river dredging, cofferdam construction, and embankment reinforcement. Background Technology

[0002] Existing river dikes mostly employ concrete casting, sandbag filling, or flat steel piles, which have drawbacks such as long construction periods, difficult dismantling, significant leakage, and poor adaptability. Ordinary steel sheet piles have weak bending resistance, unreliable connection sealing, and bulky support systems that cannot adapt to different slopes and geological conditions. Therefore, there is an urgent need for a lightweight, well-sealed, adjustable-angle, and reusable dike support structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a baffle support structure for water-proofing of mud during river construction, which facilitates water-proofing of mud during river construction.

[0004] This utility model achieves its purpose through the following technical solution: A baffle support structure for preventing water from entering the river channel during construction includes a baffle 1, a connecting hole 2, an upper horizontal bar 3, a lower fixing plate 4, a limiting groove 41, a lower fixing rod 5, a transverse fixing groove 6, a transverse fixing rod 7, and a support rod 8. The baffle 1 is a continuous sinusoidal wave-shaped bent thin steel plate with connecting holes 2 on both sides for continuous splicing; the horizontal fixing rod 7 is horizontally fixed to the back of the baffle 1 to form a back force band. The upper horizontal bar 3 and the lower fixing plate 4 respectively horizontally clamp the upper and lower sides of the horizontal fixing bar 7, and form a back rib by cross-winding of iron wires; The bottom surface of the lower fixing plate 4 is provided with a limiting groove 41 for inserting the support rod 8; The lower fixing rod 5 is fixed to the lower fixing plate 4. There is one on each side of each limiting groove 41. The outer side wall of the rod is opened with transverse fixing grooves 6 at intervals along the height direction for wire binding. One end of the support rod 8 rests on the ground and the other end rests on the back of the baffle 1. The rod body is connected to the lower fixed rod 5 through the horizontal fixing groove 6 and the wire to form a triangular support, and the support angle is adjustable.

[0005] As a further limitation of this technical solution, the baffle 1 is sinusoidal wave-shaped, with the crest facing the water and the trough facing away from the water. The connecting holes 2 on both sides adopt a quadruple seal of bolt-nut-washer-rubber gasket to achieve zero leakage splicing between the plates.

[0006] As a further limitation of this technical solution, the horizontal fixing rod 7 is a Φ20 mm Q235B galvanized round steel, which is horizontally welded to the back of the baffle 1.

[0007] As a further limitation of this technical solution, the upper crossbar 3 is a Φ48×3 mm galvanized steel pipe, and the lower fixing plate 4 is a 4 mm thick rectangular galvanized steel plate. After the two horizontally clamp the horizontal fixing bar 7, they are wrapped and tightened with galvanized iron wire in an "X" shape to form an integral back rib.

[0008] As a further limitation of this technical solution, the limiting groove 41 is a groove that runs through the entire length of the lower fixed plate 4, and the top of the support rod 8 is inserted to limit its movement laterally.

[0009] As a further limitation of this technical solution, the lower fixing rod 5 is a Q235B galvanized steel pipe, fixed on the lower fixing plate 4. There is one on each side of each limiting groove 41. A pair of transverse fixing grooves 6 are symmetrically milled on the outer wall at intervals of 50 mm. The grooves are 8 mm wide and 4 mm deep, and are used for wire binding and positioning.

[0010] As a further limitation of this technical solution, the support rod 8 is a Q235B galvanized steel pipe with an outer tube Φ32 mm, an inner tube Φ25 mm, and a length of 500–1200 mm.

[0011] As a further limitation of this technical solution, during installation, the upper end of the support rod 8 abuts against the back of the baffle 1, the lower end abuts against the ground, and the rod body is close to the corresponding horizontal fixing groove 6. Galvanized iron wire is used to cross-wrap and tighten the support rod 8 and the lower fixing rod 5 at the corresponding horizontal fixing groove 6 to form a triangular support.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are: The corrugated thin steel plate is easy to assemble and provides reliable waterproofing; the horizontal fixing rod and the upper and lower clamping steel pipes form an integral back rib, which has sufficient rigidity and small deformation; the horizontal groove of the lower fixing rod is matched with the adjustable support rod, and the support angle can be infinitely adjusted to adapt to various slopes and geological conditions; the limit groove has a direct insertion structure, which is simple to manufacture and quick to install; the full galvanized anti-corrosion system has good durability and can be reused repeatedly; no large machinery is needed throughout the process, and assembly and disassembly can be completed manually, which significantly saves construction time and costs.

[0024] The baffle is sinusoidal wave-shaped, with the crest facing the water and the trough facing away from the water. The connecting holes on both sides are sealed with a quadruple seal of bolts, nuts, washers, and rubber gaskets to achieve zero leakage between the panels.

[0025] The horizontal fixing rod is made of Φ20 mm Q235B galvanized round steel and is welded horizontally to the back of baffle 1.

[0026] The upper crossbar is made of Φ48×3 mm galvanized steel pipe, and the lower fixing plate is made of 4 mm thick rectangular galvanized steel plate.

[0029] The support rod is made of Q235B galvanized steel pipe, with an outer tube diameter of 32 mm and an inner tube diameter of 25 mm, and a length of 500–1200 mm.

[0030] During installation, the upper end of the support rod rests against the back of the baffle, and the lower end rests against the ground.

The design lifespan is ≥20 years, and the parts can be reused ≥300 times. Example 1: Standard 2m high flat ground waterproof wall Component preparation Baffle 1: 2000×1000×2.5 mm sine wave plate, wave pitch 150 mm, wave height 40 mm, Q235B, weight 32 kg; Horizontal fixing rod 7: Φ20 mm galvanized round steel, L=1060 mm, 3 rods in total; Upper crossbar 3: Φ48×3 mm galvanized steel pipe, L=1000 mm; Lower fixing plate 4: 4 mm thick rectangular galvanized steel plate, L=1000 mm, bottom surface machined rectangular limiting groove 41, 30 mm wide and 6 mm deep; Lower fixing rod 5: Φ25 mm galvanized steel pipe, L=800 mm, each outer side is milled with a transverse fixing groove (6) 8×4 mm every 50 mm; Support rod 8: Φ32 / 25 mm telescopic galvanized steel pipe, range 500–1200 mm.

[0033] Installation steps a. Place baffle 1 vertically with the crest facing the water. For the splicing of adjacent baffles: place EPDM washers, M16×60 bolts, washers, rubber pads, adjacent baffles, rubber pads, spring washers, and nuts in the connecting hole 2 in sequence. The torque is 45 N·m, the plate gap is compressed by 1.5mm, and there is zero leakage. b. Place the horizontal fixing rod 7 horizontally against the back crest and spot weld it in place; c. Press the upper horizontal bar 3 against the upper horizontal fixing bar 7, and the lower fixing plate 4 presses against the lower part. Wrap 2.0 mm galvanized iron wire in a crisscross pattern for 3 turns, tighten with pliers for 5 turns, and bend the tail end 180° to prevent loosening. d. Insert the support rod 8 into the limiting groove 41; e. The upper end of the support rod 8 abuts against the crest of the back of the baffle, and the lower end abuts against the ground. Select the nearest horizontal fixing groove 6, and tie the iron wires together with a cross-shaped binding force of ≥500 N to form a 45° triangular support.
