A four-way displacement concrete pouring device for geotechnical bridge railings

Abstract

The invention discloses a four-way displacement geotechnical bridge railing concrete pouring device, a chassis, a wheel system, a hydraulic rod, and a material storage box; two groups of wheel systems are installed on the lower surface of the chassis, and the two groups of wheel systems are respectively arranged in a cross ; The upper surface of the chassis can slide up and down to be provided with a material storage box, and a hydraulic rod is arranged between the material storage box and the chassis, and the hydraulic rod pushes the material storage box to move up and down; the adjacent side of the chassis is provided with a L shaped push handle; the wheel system includes wheel bridge, wheel arm, roller, steering rod, connecting rod, rack; the wheel arm is rotatably installed under the two ends of the wheel bridge, and the roller is installed on the wheel arm; the device is specially designed for bridges. For the pouring construction of the railing, the configured concrete can be quickly poured into the railing mold of the bridge through this device, and at the same time, the height of the discharge port can be adjusted according to the height of the railing to achieve adaptation; the wheel layout of the application can be Very good steering control, can achieve fast and precise adjustment to the target area.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a four-way displacement concrete pouring device for railings of geotechnical bridges. Background technique [0002] Concrete is one of the most important civil engineering materials in the contemporary era. It refers to a mixture made of cement, granular aggregate, water, admixtures and mineral admixtures that need to be added in an appropriate proportion; After a certain period of physical and chemical changes in the enclosed space of a certain shape, a structure with high compressive strength, good durability, a wide range of strength levels, and a shape that meets the design requirements is formed. Common concrete pouring equipment such as concrete pumps and concrete pumps Cars, belt transport pouring equipment, cranes with pouring devices, etc., are used for pouring large concrete structures. Small trolleys and dump trucks are often used for concrete pouring of structures be...

AI Technical Summary

Problems solved by technology

[0003] At present, the unit length of bridge railings requires a small amount of concrete. It is uneconomical to use large pouring equipment such as concrete pumps and pump trucks. General construction parties do not use such equipment for pouring in order to save costs. Most of them use small carts, The dump truck transports the concrete to the pouring position, and then pours the concrete into the bridge railing mold; in the actual operation process, the railing is higher than the bridge deck at a certain height, so there is a certain height difference between the railing mold and the bridge deck, small carts, dump trucks, etc. , it is impossible to adjust the corresponding height according to the situation on site, the applicability is low, and the concrete can only be filled into the bridge railing manually, which is very inefficient and consumes physical strength; The setting time of high-level concrete is inconsistent, which greatly affects the quality, and the bridge railings after forming often have cracks, which greatly affects safety

[0004] At the same time, the current solution (equipment) cannot control the poured concrete flow during the pouring process, which affects work efficiency, so it needs to be improved
