Embodiment Construction

[0045] The present invention will be further described below in conjunction with the examples. The description of the following examples is provided only to aid the understanding of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0046] refer to figure 1 Shown, the construction method of described concrete arch skeleton slope protection comprises the following construction steps:

[0047] 1) Construction preparation: site surveying and mapping determine the plane position of the fabricated arch skeleton and cast-in-situ arch skeleton, excavate the slope soil body 8 according to the design stability control requirements; determine the concrete mix ratio; prepare the devices and equipment r...

Abstract

The invention relates to a construction method of a concrete arch-shaped framework revetment. The construction method comprises the following steps of 1) construction preparation; 2) preparation of aprefabricated member; 3) preparation of an integrated framework template; 4) excavation of a framework arranging slot; 5) construction of an edge coupling beam; 6) mounting of a slip hoisting structure; 7) construction of an assembled arch-shaped framework revetment; 8) mounting of an assembled step; and 9) construction of a cast-in-situ arch-shaped framework revetment. The construction method hasthe beneficial effects that mold top cover plates are separately arranged between a first straight mold and a second straight mold, a third straight mold and a fourth straight mold, a first arc-shaped mold and a second arc-shaped mold and a third arc-shaped mold and a fourth arc-shaped mold of the integrated framework template, so that effects of concrete spouting and integrated framework template enhancing can be met synchronously; and guiding side plates are separately arranged on two sides of the fourth straight mold of the integrated framework template, so that the mounting and positioning difficulty of the integrated framework template can be reduced.

Description

technical field [0001] The invention relates to a construction method for slope protection with a concrete arched skeleton, which belongs to the field of roadbed protection and is suitable for the construction of highway roadbed slope protection engineering. Background technique [0002] The protection of subgrade slope support is an important measure to improve the stability of subgrade, and arched skeleton slope protection is a common form of protection. During the construction of arched skeleton slope protection, there are often problems such as poor control of appearance size and stability, difficulty in controlling the integrity of the skeleton, and low efficiency of on-site construction. [0003] In the prior art, there is a construction method of arched skeleton slope protection technology of subgrade slope, which is characterized in that: the foundation groove is excavated manually with skeleton slotting machine; the skeleton template is assembled with shaped steel m...
