Embodiment
[0074] This installation method is used for the construction of Line 1 of the modern tramway first phase project in Hunnan New City, Shenyang City, Liaoning Province:
[0075] 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 2 days of construction period and save construction and safety measures for every 300 meters of grooved rail track laying project. The investment cost is 158,910 yuan; the total 24,000m track laying project of this project adopts this installation method, which saves a total construction period of 160 days, and saves a total of 12,712,800 yuan in construction and safety measures.
[0076] The construction technology of the integrated rail support frame for the laying of modern tram grooved rail tracks is not adopted, and the main labor, machinery and material inputs of the 300m track using traditional construction techn...

Disclosed is a method for mounting an integrated steel rail supporting frame for adjustment of groove type steel rails of a tramcar. The integrated steel rail supporting frame is formed by assembling three sets of tooling equipment in a common steel rail supporting system into a whole. The steel rails are adjusted on a set of tooling during adjustment, space between the steel rails is adjusted through fine adjustment screws on two sides of the supporting frame, the height and the levelness of the steel rails are adjusted through vertical adjusting screws on two sides of the supporting frame, and directions of the steel rails are adjusted by depending on inclined draw bars on the supporting frame. A vertical adjusting device is added on the inner side of each steel rail to adjust the levelness of the rail bottom of the single steel rail simultaneously. Vertical adjustment screws on two sides of the steel rails can be adjusted to achieve standard technical requirements if the rail bottoms of the steel rails fail to meet standard design requirements after the steel rails are erected. According to the method, the efficiency and the accuracy of paving adjustment of groove type steel rails of modern tramcars are improved effectively, operation processes can be simplified, the construction progress can be accelerated, and the production cost can be reduced.
Description
technical field [0001] The invention belongs to the construction of modern trams, and in particular relates to an installation method of an integrated rail support frame for adjusting grooved rails of modern trams. Background technique [0002] The laying of ballastless trough track in modern tramway engineering is a technical difficulty and focus in construction. In the current rail transit engineering construction, the common rail erection method is to adjust three sets of tooling equipment at the same time. The three sets of tooling are vertical adjustment, gauge tie rods, and diagonal tie rods. During track adjustment, the height and level of the track can be adjusted through vertical adjustment in three steps. The gauge pull rods adjust the gauge of the rails, and the diagonal tie rods adjust the direction of the rails. The adjustment steps of traditional process installation and construction are cumbersome, difficult to adjust, and the pass rate after adjustment is lo...
