Embodiment 2

[0059] Such as Figure 8-11 As shown, the underwater bridge pier pier wall cleaning method and its movable support of the present invention, except that the shape of the inner space of the movable support 1 plane section is the same as the outer shape of the pier body plane section, which is circular, and the clearance size of the movable support 1 is the same as that of the pier body. Add 200mm to the size of the plane section, the steel beam 6 of the movable support 1 is made of steel pipes, and the connection between the steel beams 6 is not provided with the adjustment device 13, the clearance size in the movable support 1 cannot be adjusted, and the movable support 1 is lowered to the pier wall to be cleaned 2, after the sliding trolley 8 completes a stroke, the movable support 1 is lifted up by 50mm, the effective working diameter D of the high-pressure water jet nozzle 5 is 50mm, and the working pressure of the high-pressure pump is 10MPa, and the rest are consistent wit...

Embodiment 3

[0061] Such as Figures 12 to 15 As shown, the underwater bridge pier pier wall cleaning method and its movable support of the present invention, except that the shape of the inner space of the planar section of the movable support 1 is the same as that of the outer profile of the pier body, which is a round end shape, and the size of the inner clearance of the movable support 1 is pier Add 700mm to the size of the plane section of the body. The steel beam 6 of the movable support 1 is composed of a steel composite beam and a steel truss beam. There is no adjustment device 13 at the joint between the steel beams 6. The clearance inside the movable support 1 cannot be adjusted. The equipment 4 lowers the movable support 1 to the height position of the lowermost end of the pier wall 2 to be cleaned. After the sliding trolley 8 completes a stroke, the movable support 1 is lifted up by 300mm. The effective working diameter D of the high-pressure water jet nozzle 5 is 300mm. The wo...

Abstract

The invention refers to an underwater pier wall cleaning method and movable bracket thereof; the method is that the movable bracket is matched with a high-pressure pump to clean the underwater pier wall. The method comprises the following steps: A. designing and machining the movable bracket according to the section feature of the pier body; B. mounting the movable bracket and the additional equipment on the movable bracket; C. putting the movable bracket on the position of the pier to be cleaned in water; D. supplying high-pressure water via high-pressure pump; spraying the high-pressure water via the high-pressure water tube and high-pressure jet nozzle to clean the pier wall. The underwater pier wall cleaning method and movable bracket thereof solve the problem about repairing and reinforcing the underwater pier; the invention creates a safe, credible, economic and fast underwater pier wall cleaning method.

Description

Technical field: [0001] The invention belongs to the technical field of bridge reinforcement and restoration, and in particular relates to an underwater pier pier wall cleaning method and a movable support thereof. Background technique: [0002] Due to design defects, construction quality accidents, earthquakes or other natural disasters, ship collisions and overloading, more and more completed bridges need to be reinforced. If there are cracks or other diseases in the underwater pier body of the pier, it is usually repaired by installing a steel box within a certain range around the pier with the problem, and then pouring underwater concrete between the outer wall of the pier and the steel box. reinforcement. In order to make the newly poured concrete and the original pier wall bond well, it is necessary to clean the outer pier wall of the original pier before pouring the reinforced concrete. How to complete the underwater pier safely and efficiently, especially in deep wa...
