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 protecting the vegetation within the frame, which can not only prevent the erosion of the slope by the water flow, but also prevent the slope from being damaged. Rock and soil weathering, spalling, rockfall and other small slope deformations can achieve the effect of beautifying the natural environment. However, during the construction process, horizontal sliding between the slope and the rock foundation is often encountered, which affects the stability of the connection.

Embodiment Construction

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

[0029] Such as figure 1 , 2 , Shown in 3, 4, 5, a kind of anti-landslide construction technology of building concrete layer on slope surface comprises following construction steps:

[0030] (1) Opening holes in the rock layer: An anchor hole 2 is set on the foundation rock layer 1, and the anchor hole 2 is arranged obliquely. The depth is 2-6m;

[0031] (2) Set the anchor section: after the anchor hole 2 is opened, put a plurality of anchor cables 3 connected to each other into the anchor hole 2, the anchor cables 3 extend out of the port of the anchor hole 2, and put the grouting pipe into the anchor hole 2 At the bottom 50-100mm;

[0032] (3) Grouting of the anchorage section: After the grouting pipe is put into the anchorage hole 2, concrete is poured into the anchorage hole 2 through the grouting pipe for one-time grouting until the concrete is poured to t...

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...
