Problems solved by technology

In the general prestressed anchor cable construction, drilling rigs are often used to fix the prestressed anchor cable in the hole to achieve the function of high slope disease prevention, and by applying prestress, it can resist deep deformation and damage of the slope body. The reinforced concrete frame attached to the slope acts as a frame for the surface rock and soil of the slope body, limiting the deformation and damage of the surface rock and soil, and protec

Example Embodiment

[0028] The present invention will be further described in detail below in conjunction with specific embodiments.

[0029] Such as figure 1 , 2 As shown in, 3, 4, and 5, a construction technology for the anti-skid slope of the concrete layer of the slope building includes the following construction steps:

[0030] (1) Rock layer opening: An anchor hole 2 is opened in the foundation rock layer 1, and the anchor hole 2 is arranged obliquely, and its angle is determined by the slope 14 of the slope base 10, and is perpendicular to the slope 14 of the slope base 10. The depth is 2-6m;

[0031] (2) Set the anchoring section: After the anchoring hole 2 is opened, put a plurality of interconnected anchor cables 3 into the anchoring hole 2, and the anchor cable 3 extends out of the port of the anchoring hole 2, and put the grouting pipe into the anchoring hole 2. 50-100mm from the bottom;

[0032] (3) Grouting in the anchoring section: After the grouting pipe is placed in the anchoring hole 2...

Abstract

The invention discloses an anti-landslip construction technology for a slope building concrete layer. The anti-landslip construction technology for the slope building concrete layer includes the following construction steps of firstly, rock stratum trepanning, secondly, anchoring section arrangement, thirdly, anchoring section grouting, fourthly, anchoring section grouting compaction, fifthly, pre-tightening section arrangement, sixthly, slope face base body pouring, seventhly, pre-tightening and anchoring, and eighthly, plugging. By the adoption of the anti-landslip construction technology, a slope body and a rock body foundation can be prevented from sliding horizontally, connection is stable and firm, and construction is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-landslide construction technology of a concrete layer of a building on a slope. Background technique [0002] In recent years, with the rapid development of my country's construction industry, more and more slope projects are involved in the construction process. During the construction of deep foundation pit slopes, anchor cables are often used to organically combine the foundation and the slope surface. Together. In the general prestressed anchor cable construction, drilling rigs are often used to fix the prestressed anchor cable in the hole to achieve the function of high slope disease prevention, and by applying prestress, it can resist deep deformation and damage of the slope body. The reinforced concrete frame attached to the slope acts as a frame for the surface rock and soil of the slope body, limiting the deformation and damage of the surface rock a...
