Waterstop fixing device for water conservancy projects and using method thereof

Abstract

The invention provides a water-stop belt fixing device for hydraulic engineering and a using method thereof and discloses a device for fixing a water-stop belt through an embedded fixing structure and a using method of the device. The water-stop belt fixing device for hydraulic engineering is simple in structure, convenient to use and practical. The water-stop belt fixing device for hydraulic engineering is characterized in that a fixing frame is manufactured by folding a metal plate from the middle, the length of the folded metal plate is three to five times the height of a main body fixing frame, and an included angle exists between the upper portion and the lower portion after folding; turning grooves are formed in the two ends of the main body fixing frame correspondingly, a connecting pipe is arranged in the middle of the main body fixing frame, a hollow rod is arranged on the connecting pipe, and a slurry inlet channel is located in the hollow rod and the connecting pipe; at least one threaded sleeve is arranged on one folded surface, a compression screw corresponds to the threaded sleeve, and a compression plate is arranged on the compression screw and located between folded areas of the main body fixing frame; and a compression cushion block is arranged on the main body fixing frame and located under the compression plate. By adoption of the water-stop belt fixing device for hydraulic engineering and the using method thereof, the clamping and fixing stability of a water-stop belt can be improved, and the fixing stability of the water-stop belt in the concrete setting process is improved.

[0002] At present, in water conservancy projects, when constructing large-volume concrete, due to the requirements of the structure and construction technology, it is necessary to divide the joints at certain parts. In order to achieve the effect of water-stop and anti-seepage, water-stop belts need to be installed at the joints. Water-stop belts mainly When used for concrete structure cast-in-place, it is installed at construction joints, settlement joints, and deformation joints. It is integrated with concrete pouring to prevent leakage at joints and achieve water-stop effects. The traditional water-stop fixing method uses angle steel fixing frames or lead wires To fix the waterstop, but the integrity and position accuracy of the waterstop cannot be guaranteed, and it is easy to cause the waterstop to break and shift during the concrete pouring process, affecting the waterstop effect

[0003] The publication number is CN104453955A, a positioning fixture for tunnel waterstops, which discloses a movable splint installed vertically through bolts on the tunnel invert formwork, and elongated bolt holes are set on the horizontal bottom plate of the movable clip, and the movable splint can be Slide left and right along the plane of the inverted arch template, and the splint is formed by the inner plate of the "U"-shaped card on the inner side of the movable splint and the movable splint; the upper half of the waterstop is clamped in the splint; the "U" shape The card is buckled upside down on the splint with its bayonet facing down; a fixed horizontal screw is installed through the outer plate of the "U" shaped card, and the rod end of the fixed horizontal screw is against the outside of the movable splint; the fixed horizontal screw is adjusted so that the movable splint is in the The "U"-shaped card moves toward the inner plate of the "U"-shaped card to form a clamp for the waterstop. The above-mentioned waterstop positioning fixture is fixed on the end of the waterstop located on the outside of the concrete. The waterstop There is no positioning on the end inside the concrete. The positioning fixture can only fix the waterstop in one direction. When the concrete is poured, the end of the waterstop inside the concrete will be offset, which will affect the waterstop effect.

[0004] Application No. 201620832072.7 discloses a waterstop fixing device for water conservancy projects. Its structure includes a positioning bracket for fixing the waterstop in the concrete and a fixing bracket for fixing the waterstop outside the concrete. The positioning bracket includes splints, Adjusting mechanism and tendon rod. The splint is a 匚-shaped splint mainly composed of two horizontal plates and a vertical plate. The adjusting mechanism is set on the splint and can adjust the opening diameter of the splint. The tendon rod is vertically fixed on the vertical plate. On the outer side; the fixed bracket includes a pressure bar and a fixing bolt. The pressure bar is a 匚-shaped pressure bar mainly composed of two horizontal bars and a vertical bar. The fixing bolt vertically runs through any horizontal bar. The above scheme is When clamping the waterstop, it is only clamped by adjusting the angle between the two horizontal plates. The clamping position is linear clamping, and the fixing strength is not high. If the adjustment is too tight, the waterstop will be damaged, and During the grouting process, the combination between the concrete and the waterstop is not considered, so that the bonding between the waterstop and the concrete inside the positioning bracket is poor, and the waterstop will slip off before the concrete is completely solidified
