Problems solved by technology

[0002] At present, rockfill dams have obvious economic advantages due to the excavation of engineering buildings or the mining of local materials nearby. The cracking of the top road surface is mainly due to the characteristics of the rockfill material that determines that it must have a certain amount of deformation during construction and operation. The same, and the settlement of rockfill needs a long process, which usually takes more than a few years, so these objective factors directly determine that the settlement of the dam crest is inevitable, and the existing pavement structure of the dam crest will inevitably crack

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but not as a limitation to the present invention.

[0018] Embodiments of the present invention: a method for preventing cracking of a rockfill dam crest road, mainly carried out according to the following steps during construction:

[0019] (1) Complete transition material filling and rolling on the upper part of the dam body rockfill;

[0020] (2) After the settlement value and rate of the dam body meet the engineering requirements, start pouring the upstream wave wall;

[0021] (3) Level the surface layer of the transition material at the end of the dam crest, and lay reinforcement mesh and reinforcement rods to ensure that the laying surface is smooth;

[0022] (4) Start the construction of pavement structure, curb stone, sidewalk and anti-collision pier.

[0023] The reinforced mesh is a mesh structure, and the reinforced rods are arrange...

Abstract

The invention discloses a method and structure for preventing a rock-fill dam crest road from cracking. Metal nets and reinforced rods are arranged between the top of a dam crest tail transitional material and the road surface. The force transmission and bearing effects of the metal nets are used for modifying the deformation condition of a foundation to the same horizontal level, and the situation that the dam crest road surface cracks due to the too large concentrated load or the too large dam body sedimentation of the dam crest road surface is reduced or avoided. The structure is convenient to construct, the effect is remarkable, and the economic advantages are obvious.

Description

technical field [0001] The patent of the invention relates to a method and structure for preventing cracking of a road at the crest of a rockfill dam, and belongs to the technical field of basic treatment of water conservancy and hydropower projects. Background technique [0002] At present, rockfill dams have obvious economic advantages due to the excavation of engineering buildings or the mining of local materials nearby. The cracking of the top road surface is mainly due to the characteristics of the rockfill material that determines that it must have a certain amount of deformation during construction and operation. The same, and the settlement of the rockfill needs a long process, which usually takes more than a few years, so these objective factors directly determine that the settlement of the dam crest is inevitable, and the existing pavement structure of the dam crest will inevitably crack. Contents of the invention [0003] The purpose of the present invention is...
