High-pressure water gun chiseling construction equipment and method

Abstract

The invention discloses a high-pressure water gun dabbing construction device and method, and belongs to the field of water conservancy projects. The device and the method aim at improving the dabbingeffect. According to the key points in the technical scheme, the device comprises a water spraying gun, one end of the water spraying gun communicates with a pressure pump, a supporting frame is arranged on the outer side of the front end of the water spraying gun, the supporting frame comprises a connection rod fixed to the water spraying gun, a supporting rod is connected to the connection rod,a front vertical rod is fixed to the connection rod, a rear vertical rod is connected to the connection rod, an angle adjusting mechanism is arranged on the rear vertical rod, a rotating mechanism isfixed to the supporting frame, the rotating mechanism comprises an adapter rod fixedly connected with the supporting frame, a limiting sleeve is fixed to the adapter rod, a compressed spring in a compressed state is arranged in the limiting sleeve, a fixing plate is fixed to the side face of the water spraying gun in a sleeving mode, a limiting groove is formed in the fixing plate, and a limitingball which penetrates through the adapter rod to be partially embedded into the limiting groove is placed into a port, facing the adapter rod, of the limiting sleeve. The problem that the high-pressure water gun dabbing effect is poor is solved.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a high-pressure water gun chiseling construction equipment and method. Background technique [0002] As a commonly used composite material, concrete is widely used in various engineering industries. When pouring concrete for some structures, in order to improve the construction quality and the constraints of realistic conditions, it is necessary to pour the structures in sections. Construction joints will be left during segmental pouring. Although construction joints are often set in the part of the concrete structure where the shear force is small, the bonding quality at the construction joints also has an important impact on the quality of the concrete poured in segments. Before the construction joints are poured with concrete, the sides of the construction joints need to be chiseled to improve the connection strength of the concrete at the construction joints. ...

AI Technical Summary

Problems solved by technology

[0006] Although the above-mentioned construction method uses the pressure water of the high-pressure water gun to wash the part to be chiseled to realize chiseling, the reaction force of the high-pressure water ejected when the high-pressure water gun is used is relatively large, and the distance between the high-pressure water gun and the surface to be chiseled is unstable. The force of the high-pressure water sprayed from the water gun on the chiseled surface changes frequently, and it is impossible to determine whether the retarder is rinsed clean, and the chisel effect cannot be determined, and the chisel effect needs to be improved
