Problems solved by technology

[0002] On the surface of today's water conservancy dams, impacted by rainwater or exposed to the sun, cracking often occurs, and the pores need to be sealed to ensure the normal operation of the dam. Currently, composite materials are generally embedded in the pores for sealing and fixing. However, since the composite material enters the pores without external plugging, leakage often occurs, resulting in poor plugging effect and affecting the overall safety of the dam.
[0003] Publication No. CN110145340A discloses a coal seam fissure grouting plugging device. The end of the plugging mechanism in the fissure can extend into the coal seam fissure to seal the fissure inside the coal seam. The outer surface is sprayed with high pressure and the cracks on the outer surface of the coal seam are coated with a layer of plugging slurry to form a protective layer on the outer surface of the coal seam. The plugging device is directly covered and blocked, without a stable structure, and the plugging stability is poor

Embodiment 1

[0018] A water conservancy dam fissure sealing device of the present invention is realized in the following way: a water conservancy dam fissure sealing device of the present invention consists of a main body plate (1), an extrusion cover (2), a vertical tube (3), and a drill bit (4 ), conical airbag (5), push rod (6), airtight plug (7), storage hole (8), fixing groove (10) and protruding ring (11), the four main body plate (1) Standing tubes (3) are arranged at the corners, a level is placed on the main board (1), the main board (1) is an arc-shaped board, and four corners of the main board (1) are respectively opened with Through slot, the vertical tube (3) is provided with a fixing slot (10) near the top, the vertical tube (3) is stuck in the through slot through the fixing slot (10), and the through slot is built with locking teeth, so The fixing slot (10) is provided with a slot corresponding to the teeth, and the inner wall of the top of the vertical tube (3) is provided...

Embodiment 2

[0021] The difference between this embodiment and Embodiment 1 is: the conical airbag (5) is replaced by a spiral airbag (9); when in use, the contact area with the ground is increased, the filling space is increased, and the device is more stable; The main body plate (1) is designed as a curved plate, which can be arched into the pores to compress the positions of the pores to ensure the sealing effect;

[0022] The through slot is built with locking teeth, and the fixed slot (10) is designed with a slot corresponding to the locking teeth, which can lock between the through slot and the column, and avoid the impact of the relative rotation of the two on pushing;

[0023] The design of the convex ring (11) can tap the thread groove in the convex ring (11) and cooperate with the thread on the push rod (6), so as to avoid tapping the vertical cylinder (3);

[0024] The extrusion cover (2) is equipped with anti-skid design, which increases the friction between the hand and the ex...

Abstract

The invention provides a water conservancy dam crack plugging device and discloses a stabilizing structure. According to the stabilizing structure, a conical airbag swells to be embedded into a dam body to carry out stabilizing, a crack is reduced, and stability is good. The water conservancy dam crack plugging device is characterized in that vertical cylinders are arranged at four corners of a main body plate correspondingly, the main body plate is provided with a gradienter, through grooves are formed in the four corners of the main body plate correspondingly, fixing grooves are formed in the portions, close to the top ends, of the vertical cylinders, the vertical cylinders are clamped into the through grooves through the fixing grooves, clamping teeth are arranged in the through grooves, clamping grooves corresponding to the clamping teeth are formed in the fixing grooves, protruding rings are arranged on the inner walls of the top ends of the vertical cylinders, pushing rods are arranged in the protruding rings in a screw connecting manner, the ends of the pushing rods extend into the vertical cylinders downwards, closed plugs are arranged at the ends of the pushing rods, the other ends of the pushing rods extend out of the vertical cylinders upwards, extruding covers are fixedly connected with the other ends of the vertical pushing rods, and the extruding covers are provided with antiskid stripes.

Description

technical field [0001] The invention relates to a fissure sealing device for a water conservancy dam, which relates to a structure for stabilizing a workbench in geological survey, and belongs to the field of geological survey. In particular, it relates to a stabilizing structure which is embedded in a dam body by conical airbag expansion, reduces gaps, and has good stability. Background technique [0002] On the surface of today's water conservancy dams, impacted by rainwater or exposed to the sun, cracking often occurs, and the pores need to be sealed to ensure the normal operation of the dam. Currently, composite materials are generally embedded in the pores for sealing and fixing. However, since the composite material enters the pores without external plugging, leakage often occurs, resulting in poor plugging effect and affecting the overall safety of the dam. [0003] Publication No. CN110145340A discloses a coal seam fissure grouting plugging device. The end of the pl...
