Problems solved by technology

[0002] In recent years, during the rainy season, the highways in the western mountainous areas have often been damaged by geological disasters. Continuous heavy rainfall has induced landslides and river surges, resulting in the erosion and smashing of the retaining structures of the roadbeds near the rivers. The special protective structures set up on the inner slopes damage
In the emergency protection road section, the existing plan is to re-install the blocking structure on the site, which takes a long time to rescue, and obviously cannot meet the requirements of rapid protection and containment of disaster development. How to quickly realize the construction of the blocking structure is an urgent need for the engineering community to solve The problem

Embodiment

[0038] Example: such as Figure 1 to Figure 5 As shown, a permanent-facing combined retaining wall structure that is quickly assembled on site includes a frame unit close to the side slope of the roadbed and a protective net 5 arranged outside the frame unit;

[0039] The frame unit includes a plurality of horizontal tubes 1 and a plurality of supporting units;

[0040] The supporting unit includes a horizontal tube 1 and a column unit, the column units are two, and the supporting unit is arranged along the width direction of the roadbed;

[0041] The column unit includes a vertical pipe 4 and a six-way pipe 2. The horizontal pipe 1 is necked at both ends, and the vertical pipe 4 is necked at one end. The vertical pipe 4 and the horizontal pipe 1 have the same size as the six-way pipe 2. Match, the necked end of the vertical pipe 4 is inserted into the six-way pipe fitting 2;

[0042] The same sides of the two column units are connected by a horizontal tube 1, and both ends of the ho...

Abstract

The invention provides a permanent / temporary retaining wall structure quick to splice on site and a construction method. The construction method includes the following steps of prefabricating transverse pipes, six-way pipe fittings, grouting pipes, vertical pipes and protection nets in a factory; quickly splicing frame units on a roadbed slope and increasing the length of the frame units in accordance with the damage situation of the roadbed slope; mounting the protection nets on the outer sides of the frame units and filling the frame units with on-site broken stone; inserting the grouting pipes into the vertical pipes in the frame units, and inserting the grouting pipes into a roadbed for grouting; and erecting frameworks on the outer sides of the frame units and pouring concrete after grouting is completed and traffic organization of the roadbed ends so as to form a permanent retaining wall support. By means of the scheme, the retaining wall is spliced on site with the prefabricatedcomponents, so that rescue time is saved; quick forming can be realized at the traffic organization stage, so that the damage of landslide to roads and passers-by is reduced, and the slope is furtherstabilized; and the permanent retaining wall support can be formed to provide safety for a long time.

Description

Technical field [0001] The invention relates to the field of roadbed traffic safety protection facilities, and in particular to a permanent and adjoining combined retaining wall structure that is quickly assembled on site and a construction method. Background technique [0002] In recent years, during the rainy season, the highways in the western mountainous areas are often damaged by geological disasters. Continuous heavy rains have induced landslides and river surges, causing the river-side subgrade retaining structure to be washed out and destroyed, and special protective structures are set up on the inner slope damage. In the emergency protection passage section, the existing plan is to re-install the blocking structure on site, and the rescue time is relatively long. Obviously it cannot meet the requirements of rapid protection and restraining the development of disasters. How to quickly realize the construction of the blocking structure is an urgent need for the engineering...
