Abstract

The invention discloses an intelligent mud jacking system for a magnetic levitation track beam. The system comprises corrugated pipes arranged in all reserved pore passages in the track beam, wherein a mud inlet pipe and a mud outlet pipe are connected with one ports of the two different corrugated pipes, respectively; other ports of all corrugated pipes are communicated with each other through a plurality of connecting pipes to form a mud injection passage; the mud inlet pipe and the mud outlet pipe are connected with a mud jacking device, respectively; and the mud jacking device is used for jacking cement mud for the track beam into the mud injection passage from the mud inlet pipe and enabling the cement mud to flow out from the mud outlet pipe and enter the mud jacking device; therefore, a mud jacking circulation is formed. According to the intelligent mud jacking system for the magnetic levitation track beam, disclosed by the invention, sealed circulated mud jacking for each corrugated pipe of the track beam can be achieved; a defect of non-uniform strength of the track beam caused by non-uniform mud filling in the corrugated pipes of the track beam can be effectively prevented; the mud can be filled into the track beam at one time; the time and cost are saved; and the mud injection efficiency is increased.

Description

technical field [0001] The invention relates to the field of bridge design and construction, in particular to an intelligent grouting system for maglev track beams. Background technique [0002] Medium and low-speed maglev trains have technical characteristics such as low vibration, low noise, fast acceleration, small turning radius and strong climbing ability, and have good application prospects in the field of urban rail transit. The design, manufacture and construction technology of the maglev track beams used by medium and low speed maglev trains has always been a technical difficulty. The manufacturing technology of the track beam, durable concrete construction technology, tensioning process, transfer technology, overcoming concrete creep and arching, and installation quality control measures are relatively complicated. The prefabricated dimensions of the track beam require high precision. The strength and elastic modulus of the track beam must meet the requirements. ...
