Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] Such as figure 1 Shown, protective slope construction method of the present invention comprises the following steps:

[0023] Step 101: Determine the position of the upper soil layer to be excavated on the upper operation surface of the base body, and set an upper reinforcement body extending into the base body at the end of the upper layer to be excavated.

[0024] Step 102: Excavating the upper layer to be excavated to form a lower operating surface, the bottom of the upper reinforcing body is lower than the lower operating surface.

[0025] Step 103: Set the lower reinforcing body extending into the matrix on the lower operating surface in such a manner as to be in contact with the upper reinforcing body, and the soil body corresponding to the lower operating surface forms the lower soil layer to be excavated.

[0026] Step 104, repeat step two and step three un...

Abstract

The invention discloses a method for constructing a protective slope. The method comprises: Step 1, determining the position of the upper layer to be excavated on the upper operation surface of the base body, and setting an upper layer reinforcing body extending into the base at the end of the upper layer to be excavated; Step 2, excavating the upper layer to be excavated The bottom of the upper layer of reinforcement is lower than the bottom of the lower layer of operation surface; step 3, the lower layer of reinforcement extending into the matrix is ​​set on the lower layer of operation surface in a manner that is in contact with the upper layer of reinforcement, and the bottom of the lower layer of operation surface The corresponding soil forms the lower soil layer to be excavated; Step 4, repeat Step 2 and Step 3 until the earthwork excavation is completed, and the multiple reinforcements in contact form a slope protection body, and the exposed surfaces of multiple reinforcements form a The protective surface of the slope protection body.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a method for constructing a protective slope. Background technique [0002] During railway and / or road construction in mountainous areas, it is often necessary to excavate earth at a higher level of terrain to create a smaller slope between a higher level of terrain and a lower level of terrain. [0003] In the earth excavation of the prior art, the road is usually directly excavated directly on the loose soil foundation. However, during the excavation process, the retaining wall formed by loose soil often causes the excavated part to collapse, which seriously affects the construction progress and construction safety. Therefore, be badly in need of improving this construction method. Contents of the invention [0004] In view of the above problems, according to the present invention, a protective slope construction method is proposed, including: determining the position of th...
