Embodiment Construction

[0027] refer to Figure 1-Figure 12 , the installation and construction method of a concrete sound barrier for busy trunk lines described in the present invention will be described in detail.

[0028] A construction method for installing a concrete sound barrier on a busy trunk line, comprising the following steps, the process is as follows: figure 1 Shown:

[0029] Step 1: Construct pile foundation 1 at the railway shoulder according to the design position, such as Figure 5 As shown, a number of H-shaped steel columns 3 arranged at intervals and parallel to each other are fixedly connected to the pile foundation 1 through the embedded parts 2, and the H-shaped steel columns 3 are located in the vertical direction, such as Figure 7 As shown; the H-shaped steel column 3 is made of H-shaped steel. According to the design requirements, the standard span of the adjacent embedded part 2 is 4m, and the error is -10~+20mm, because under normal circumstances, the length of the sta...

Abstract

The invention belongs to the technical field of railway trunk line sound barrier installation, relates to installation of concrete acoustic boards, in particular to a busy trunk line concrete sound barrier installation and construction method, and solves the technical problems in the background technology. According to the construction method, the H-shaped steel stand columns and the right triangle supporting frames are used as rail supports, the rail is erected on the side away from the existing railway, the hoisting moving trolley and the transporting trolley are arranged on the rail, and the concrete acoustic board is transported and hoisted through the ra By means of the construction method, the concrete acoustic board is fast and convenient to install, the problem that large machines and tools cannot be used on an existing operation line is solved, interference to the existing operation line is avoided, installation work can be efficiently and fast completed under the condition that transportation is not interrupted, the construction efficiency is remarkably improved, the technology is advanced, and the construction cost is reduced. Obvious social benefits and economic benefits are obtained.

Description

technical field [0001] The invention belongs to the technical field of installing sound barriers on railway trunk lines, and relates to the installation of concrete sound-absorbing panels, in particular to a method for installing and constructing concrete sound barriers on busy trunk lines. Background technique [0002] With the gradual improvement of the economic level, people's living conditions have been significantly improved, and the daily travel methods have also shown diversified development, and strict standards have been put forward for transportation. The transportation sector has promoted the development process of the transportation industry through continuous technological innovation and exploration. Railway is an indispensable means of transportation. [0003] Most of the non-electrified railways have been built for a long time. At the beginning of construction, there were no corresponding environmental protection measures or the measures were not perfect. Wit...
