Embodiment 1

[0026] Embodiment 1: a kind of upright counterweight type lightweight mobile cofferdam, such as figure 1 As shown, the main frame includes wading columns 103, crossbeams 104, side beams 105, and auxiliary beams 106 parallel to the crossbeams 104, etc. are interconnected to form a frame structure. The upper ends of the wading columns 103 on both sides are fixed with the crossbeam 104 and the auxiliary beam 106 through the corner connectors 107, and the lower ends are fixed with the bottom connecting rods through the corner connectors 107, and then the water retaining panels are fixed to form a wading wall. The cross beam 104, the side beam 105 and the side bottom bar form a triangular side frame, and then the water retaining panel is fixed to form a side wall. The main structure of the cofferdam is surrounded by the associated wading walls and side walls, and the inner side is the working area. In addition, a skirt-type water-stop rubber pad is installed on the lower edge of e...

Embodiment 2

[0030] Embodiment 2: another kind of upright counterweight type lightweight mobile cofferdam, such as Figure 4-8As shown, the main frame 1 is included, the main frame is equipped with a traction end 12, the traction end is a steel pipe, and the upper end of the traction end 12 is connected and fixed with the fixed pile 14 on the horseway 13 by a steel cable 18, so as to prevent the cofferdam from being damaged due to its own weight and upstream water flow. The horizontal thrust slides on the bank slope 15 to improve the overall anti-skid performance of the cofferdam; the main frame 1 is a triangular prism frame, and the triangular prism is placed horizontally, that is, the side edges of the triangular prism are set horizontally. In this embodiment, the main frame 1 is Right-angled triangular prism frame, the left and right sides of the triangular prism are right-angled triangles parallel to each other, and the upper surface 101 of the main frame is perpendicular to the rear fa...

Abstract

The invention relates to the technical field of repairing equipments for hydraulic engineering canal slopes, in particular to an upright counterweight lightweight mobile cofferdam. The upright counterweight lightweight mobile cofferdam comprises a main frame and a water retaining panel, wherein a support plate is fixed between a cross beam and a side beam, studs are vertically mounted on the support plate and respectively extend outwardly, counterweight clamping slots are formed in adjacent studs, a plurality of independent counterweight blocks are hung in each counterweight clamping slot, positioning columns are arranged on two sides of each counterweight block, sliding vertical grooves are formed in both sides of each counterweight clamping slot, a limit groove is formed in the side wall, close to the water retaining panel, in each sliding vertical groove, the positioning columns can slide down along the sliding vertical grooves and are clamped in the limit grooves, bolt holes are formed on the front sides of the counterweight clamping slots, and the inner ends of fixes bolts penetrate through the bolt holes to be propped against the counterweight blocks; the rear vertical surface of the main frame and the outer lateral side of a side frame are wading walls, light water retaining panels are mounted on the wading walls, the inner sides of the water retaining panels surround waterproof working cavities, and skirt-type waterproof rubber pads are mounted on the lower edges of the water retaining panels. The upright counterweight lightweight mobile cofferdam disclosed by the invention can be quickly mounted and disassembled, is adjustable in weight of counterweight bodies and can adapt to various working conditions.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering canal slope repair equipment, in particular to an upright counterweight light mobile cofferdam. Background technique [0002] In recent years, with the gradual expansion of the city scale, urban landscape water and domestic water are also increasing. In order to meet the water demand of the city, many artificial channels have been built within the city and between cities, ranging from the South-to-North Water Diversion to various landscape channels. With the passage of time, it is inevitable that the side slope of the repaired channel will be partially scoured, cracked and other damage phenomena. These hidden dangers not only affect the water passing capacity of the channel, but the long-term water flow will also make the cracks and gaps continue to expand, and even threaten the safety of the entire channel and the living safety of residents on both sides of the channel, cau...
