Problems solved by technology

[0003] In the sound barrier of the known technology, the sound barrier plate needs to be installed on the I-beam through bolts, and the sound barrier column is connected to the foundation with bolts. The base layer strength of the current sound barrier plate is not high enough. On the other hand, if the strength of the base layer is not high, the stability of the installation of the sound barrier board is not high

Abstract

The invention discloses a construction process of a bridge insertion-plate-type noise barrier. The construction process comprises the steps of selecting materials to form a mixture, mixing 42.5 cementwith the mixture, allowing the amount of the cement to be 2.5-4.5% of the mixture, allowing the amount of water to be 4-6% of the mixture, laying a bottom base layer through the mixture, laying an I-beam on the bottom base layer, uniformly punching through holes in the surface of the I-beam, performing measurement and lofting of pile positions of steel anchor pipes, inserting the steel anchor pipes into the through holes of the I-beam, preparing and performing grouting, and paving a surface base layer after grouting. According to the construction process of the bridge insertion-plate-type noise barrier, the I-beam is pre-embedded between the bottom base layer and the surface base layer so that the stability of the I-beam can be improved and the noise barrier can be more stably connected to the I-beam in installation. The steel anchor pipes are inserted into the I-beam to provide larger horizontal resistance for guardrails and the noise barrier by virtue of the superior anchoring performance of the steel anchor pipes which are deeply anchored in the ground so as to ensure the long-term safe use of the upper structure, improve the construction quality of the base layers, prolong theservice lives of the base layers of the noise barrier, and improve the installation stability of the noise barrier.

Description

technical field [0001] The invention relates to the technical field of sound barriers, and more specifically relates to a construction technique for a bridge insert type sound barrier. Background technique [0002] With the rapid development of highways, railways, and urban rail transit, sound barriers occupy an important position in traffic noise control technology, and are currently recognized as one of the most effective means of controlling traffic noise at home and abroad. [0003] In the sound barrier of the known technology, the sound barrier plate needs to be installed on the I-beam through bolts, and the sound barrier column is connected to the foundation with bolts. The base layer strength of the current sound barrier plate is not high enough. On the other hand, if the strength of the base layer is not high, the stability of the installation of the sound barrier board is not high. Contents of the invention [0004] The object of the present invention is to provi...
