Construction method of beam transport channel in horn-mouth section of island-type station

Abstract

The invention discloses a construction method of a beam transport channel in a horn-mouth section of an island-type station, which comprises the following steps of performing cast-in-situ constructionon a single-span two-hole single-line simply-supported beam by adopting a bracket, wherein an inner lateral wing edge is temporarily not poured during construction, arranging a two-beam connecting structure. After the strength reaches 100%, a double-line beam-transporting vehicle passes through two single-line simply-supported beams, and each single-line simply-supported beam respectively bears agroup of load wheels of the double-line beam-transporting vehicle. After the beam transportation is finished, the two single-wire simply-supported beams are respectively moved to the design positionsof an operation state, and the beam wings missing from the single-wire simply-supported beams are poured. The construction method of a beam transport channel in a horn-mouth section of an island-typestation has the advantages that a single-wire simply-supported beam which is erected originally is utilized to construct the beam-transporting channel, the channel construction cost is saved, the operation method is simple and easy, different construction conditions can be adapted, the transportation efficiency of the beam body is improved, and the construction state of the original single-line simply-supported beam can be quickly restored after the beam transporting vehicle passes, so that the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of beam transport, and in particular relates to a method for constructing a beam transport channel in the bell mouth section of an island-type station. Background technique [0002] In the existing beam erection construction, a beam truck is used to transport the beam to be constructed from the ground to the area to be constructed, and then the beam is installed at a preset position to be constructed by hoisting equipment. The above scheme has the following problems: because the beam body relies on ground transportation, the transportation efficiency is low; due to the constraints of the environment and terrain on the construction site, it is impossible to lay roads that meet the requirements for beam transportation; because the structure of the beam body is usually large in size, The roads at some construction sites are uneven, and beam transport vehicles cannot pass through. [0003] The existing method o...

Problems solved by technology

The above scheme has the following problems: because the beam body relies on ground transportation, the transportation efficiency is low; due to the constraints of the environment and terrain on the construction site, it is impossible to lay roads that meet the requirements of the beam transportation on site; because the structure of the beam body is usually large, The roads at some construction sites are not level, and beam transport vehicles cannot pass through

The existing temporary Bailey truss erection is cumbersome, affecting construction efficiency
