Problems solved by technology

Although the skeleton structure of prefabricated concrete blocks has been applied in the test section of highway engineering, due to the many types of prefabricated blocks and complex block shapes, the application in actual engineering still has certain limitations. In terms of the specific process and design and construction methods of the skeleton, further optimization and improvement are still needed

Embodiment 1

[0050] Such as figure 1 As shown, a kind of railway slope prefabricated and assembled post-casting skeleton slope protection structure of the present invention includes: multiple slope protection units, inspection ladder steps 9, concrete foot protection 7 and post-cast concrete core column 8, and multiple slope protection units repeat The combined form extends longitudinally and vertically on the railway slope (wherein, the longitudinal direction refers to the length direction of the slope, and the vertical direction refers to the height direction of the slope);

[0051] Each slope protection unit is composed of a main frame and a supporting frame, which are used to limit the pouring range of the post-cast concrete core column 8 on the slope. The main frame is composed of a plurality of side prefabricated panels 1 and a plurality of top prefabricated panels 11 Assembled, a plurality of said side prefabricated panels 1 are assembled into the side main frame on both sides of th...

Embodiment 2

[0062] Such as figure 2 As shown, on the basis of Embodiment 1, the difference lies in that: the shape of the top main frame is herringbone, so that the slope protection units can be assembled into a herringbone frame.

[0063] The slope protection unit is assembled into a herringbone frame through the main frame and the supporting frame, wherein: 6 side prefabricated panels 1 are assembled to form the side straight section of the chevron, 8 top prefabricated panels are assembled to form the top section of the chevron, and 8 The support frame is assembled to be arranged above the top section of the chevron, and is parallel to the top section to form a chevron section.

[0064] Furthermore, the side prefabricated panels 1, the top prefabricated panels 11 and the support frame precast panels 10 are made of cement boards.

Embodiment 3

[0066] Such as Figure 6 As shown, a kind of railway slope prefabricated and assembled post-casting skeleton slope protection structure of the present invention comprises a plurality of slope protection units, inspection ladder steps 9, concrete foot protection 7 and post-cast concrete core column 8, and a plurality of slope protection units are as follows: The form of repeated combination extends longitudinally and vertically on the railway slope;

[0067] Each of the slope protection units is composed of a plurality of main skeletons and support frames assembled to form a square, which is used to limit the pouring range of the post-cast concrete core column 8 on the slope, and the main skeleton is composed of a plurality of side prefabricated panels 1 assembled. The two right-angled sides adjacent to the top of the square, the support frame is assembled from a plurality of support frame prefabricated panels 10 to form the two adjacent right-angled sides at the bottom of the ...

Abstract

The invention discloses a railway slope prefabricated and assembled post-poured framework slope protection structure which comprises a plurality of slope protection units, inspection ladder steps, concrete foot guards and post-poured concrete core columns. The slope protection units extend longitudinally and vertically on a railway slope in a repeated combination mode; each slope protection unit is formed by assembling a main framework and a branch framework and used for defining the pouring range of the post-poured concrete core columns on the slope surface; the inspection ladder steps are arranged on the side surfaces of the slope protection units; the concrete foot guards are arranged at the lower parts of the slope protection units; the post-poured concrete core columns fill external gaps between the slope protection units. Precast cement boards are adopted, the weight of each precast cement board is small, people can conveniently carry and assemble the precast cement boards, the bottoms of the precast cement boards are effectively fixed through steel drill rods and concrete cushion blocks, and the tops of the precast cement boards are fixed through fixing clamping grooves. Compared with a traditional steel formwork, the using number of concrete formworks of the framework protection structure is reduced to 0, the formwork disassembling process is omitted, and construction is more efficient.

Description

technical field [0001] The invention belongs to the technical field of railway embankment slope protection engineering, and in particular relates to a prefabricated and assembled post-casting skeleton slope protection structure for railway slopes and a construction method thereof. Background technique [0002] There are a large number of embankment and cutting slope projects in the construction of mountainous railways in my country, and the number and types of slope protection projects are large, and the amount of protection projects in actual projects is huge. The railway slope protection project mainly adopts concrete pouring construction, the formwork support and turnover are large, the construction efficiency is low, and the quality is difficult to control. As a green and environmentally friendly emerging technology, prefabricated assembly technology is an important development direction for the industrialization of construction engineering, and it has received more and ...
