Embodiment Construction

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0022] The invention adopts the cut bamboo to protect the foundation, and the slope rate is basically consistent with the natural slope rate of the original slope, and the lateral earth pressure bears is consistent with the basic stress principle. Through the analysis of the force form of the cut bamboo protection foundation, the cut bamboo protection foundation can meet the characteristics of large lateral earth pressure.

[0023] The specific content of this process is as follows:

[0024] (1), site cleaning

[0025] Determine the position of the bridge pier, carry out construction lofting, and clean up the site within the contour line according to the size of the bamboo-cut foundation, so as to prepare for the next step of the roof beam construction;

[0026] (2), top beam con...

Abstract

The invention discloses a construction method for an environment-friendly cut bamboo type bridge pier and abutment excavation protective foundation. The construction method specifically includes the following steps of a site cleaning, b top beam construction, c layered soil construction and bottom beam construction, d bridge pier and abutment construction according to normal construction and e backfill construction and greening recovery. The construction method is used for construction of nearby residential buildings, a construction hinterland is narrow and long, water and soil conservation needs can be met, the impact of project construction on a local construction environment can be reduced, natural landscape can be maintained, and the safety of life and property of nearby residents canbe ensured.

Description

technical field [0001] The invention relates to the technical field of slope excavation and foundation protection for railway and highway bridge engineering, in particular to a construction method for excavating and protecting foundations for bridge pier abutments of green and environment-friendly cut bamboo type. Background technique [0002] The excavation of bridge piers near residential buildings, narrow construction sites, and water and soil conservation needs generally adopts traditional methods, that is, large-scale excavation of slopes, so that the quality of slope protection cannot be effectively guaranteed, and it will also affect the protection of the local ecological environment. Cause different degrees of damage, especially cause greater safety hazards to nearby residents. Contents of the invention [0003] The invention solves the deficiencies of the prior art and provides an environment-friendly and environment-friendly construction method for excavating and...
