Problems solved by technology

[0002] The concrete pouring of the integral track bed in the modern tramway track project is constructed on the existing municipal road, the social vehicle flow of the municipal road is large, the road cannot be completely closed for construction, and at the same time, the cross-sectional area of ​​the molded concrete is small, and the pouring section is long, so the traditional construction method is adopted. Serious waste of pouring concrete

Embodiment

[0039] Line 1 of the modern tramway first phase project in Hunnan New City, Shenyang City, Liaoning Province adopts this method of construction:

[0040] After comparing the installation costs of two sections of grooved rail integral ballast track laying project with the same structure type in this project, this installation method can save 0.5 days of construction period and save construction and safety measures for every 300 meters of grooved rail track laying project. The investment cost is 271 yuan; the total 24,000m track laying project of this project adopts this installation method, which saves a total construction period of 80 days, and saves a total of 21,680 yuan in construction and safety measures.

[0041] The construction technology of the mobile chute for the concrete pouring of the integrated track bed of modern trams is not adopted, and the main labor, machinery and material inputs of the 300m track concrete pouring constructed by the traditional construction te...

Abstract

Disclosed is a utilization method for a movable chute for concrete pouring of a monolithic track bed of a modern tramcar. A track structure is used for manufacturing a movable groove type concrete pouring device, sliding wheels for moving are arranged under a groove type concrete chute, and the groove type concrete chute is moved longitudinally during concrete pouring. The method comprises the construction steps of measuring the concrete molding distance; manufacturing sliding wheel devices and the chute; splicing the movable chute; arranging the movable chute in position; and performing concrete pouring. According to the utilization method, the operation is simple, convenient and quick, concrete pouring times of monolithic track beds of the modern tramcar are controlled effectively, the construction period can be saved, the construction cost can be reduced, and the safety risk can be reduced greatly.

Description

technical field [0001] The invention belongs to the construction of modern trams, in particular to a method for using a mobile chute for concrete pouring of the integral track bed of modern trams. Background technique [0002] The concrete pouring of the integral track bed in the modern tramway track project is constructed on the existing municipal road, the social vehicle flow of the municipal road is large, the road cannot be completely closed for construction, and at the same time, the cross-sectional area of ​​the molded concrete is small, and the pouring section is long, so the traditional construction method is adopted. The process of pouring concrete wastes a lot. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, provide a method for using the mobile chute for concrete pouring of the integral track bed of modern trams, and solve the technical problems of difficulty in mold entry and serious waste of materials in ...
