Problems solved by technology

[0002] At present, most of the subway depots in the country use cast-in-place concrete columns, but it is difficult to control the verticality, top surface elevation, and pre-embedding accuracy of track fixtures for small cast-in-place concrete columns. The amount of secondary transportation of materials such as column formwork and reinforced steel pipes is relatively large

Embodiment

[0018] A construction method for inspection pit steel column rail support system, refer to Figure 1-4 , including the following steps:

[0019] S1. Positioning and setting out of track bed steel columns: After the construction of track bed cap cushion layer 1 is completed, according to the position of ballast bed steel columns in the drawing, snap wires to position at the corresponding parts of the cushion;

[0020] S2. Pre-embedding of high-strength bolts in track bed steel columns: if figure 2 As shown, after the tying of the foundation cap 2 of the track bed is completed, M16 high-strength bolts 3 are pre-embedded, and two M16 high-strength bolts 3 are pre-embedded in each steel column 4. 20 connection and fixation to ensure that the upper part of the M16 high-strength bolt 3 is fixed, and the lower part of the M16 high-strength bolt 3 is fixed by ¢6 steel bars 6 spot welding to ensure that the M16 high-strength bolt 3 is fixed as a whole; among them, the M16 high-streng...

Abstract

The invention provides a construction method of an inspection pit steel stand column track supporting system. The construction method comprises the steps of track bed steel stand column positioning and paying off, track bed steel stand column high-strength bolt pre-burying, steel stand column installing and leveling, track vibration reduction fastener assembly installing, track supporting jig frame and track fixing and hoisting and the like. The problems that the perpendicularity, the top surface elevation and the track clamp embedding precision of the cast-in-place structure concrete small stand column are not accurate can be solved.

Description

technical field [0001] The invention relates to the technical field of track support system construction, in particular to a construction method for a steel column track support system in an inspection pit. Background technique [0002] At present, most of the subway depots in the country use cast-in-place concrete columns, but it is difficult to control the verticality, top surface elevation, and pre-embedding accuracy of track fixtures for small cast-in-place concrete columns. The amount of secondary transportation of materials such as column formwork and reinforced steel pipes is relatively large. Contents of the invention [0003] Aiming at the above-mentioned prior art, the present invention proposes a construction method for a steel column rail support system in an inspection pit. [0004] The invention provides a construction method for inspection pit steel column rail support system, comprising the following steps: [0005] S1. Positioning and setting-out of trac...
