Problems solved by technology

[0004] Among them, the masonry retaining wall is a masonry made of dry or mortared stones. The current stone masonry retaining wall is not carefully screened for the masonry in the early stage, which may easily lead to a decrease in the protection ability.

Embodiment Construction

[0014] Below in conjunction with embodiment the present invention is described in more detail.

[0015] The method of dry masonry slope protection includes the following steps:

[0016] Step 1. Use rubble masonry and pebble masonry as the masonry body. The rubble masonry in the rubble masonry is block-shaped, and the thickness of the middle part is greater than or equal to 20cm. Small rubble with a thickness of 5-15cm in the middle can also be used to plug the joints. The amount of small rubble is 0.1-10% of the weight of the masonry at this place, the thickness of the pebbles in the pebble masonry is less than or equal to 30cm, and the ratio of length to thickness is between 1.0-1.5;

[0017] Step 2, leveling and compacting the downstream slope to make the slope smooth;

[0018] Step 3, transport the selected rocks to the filling part for filling;

[0019] Step 4: On the working surface that has been masonry, set up a protective fence with a 2mm thick steel mesh, and set a ...

Abstract

The invention provides a dry stone pitching method. A rubble masonry and a pebble masonry serve as a masonry body. Rubble in the rubber masonry is of a block shape, the middle thickness of the rubble is larger than or equal to 20 cm, the thickness of pebbles in the pebble masonry is smaller than or equal to 30 cm, and the ratio between the length and the thickness ranges from 1.0 to 1.5. A downstream slope is flattened and punned so that the slope is smooth; selected rock blocks are conveyed to a filler portion for filling; ultimately, a protective fence is formed through a steel mesh with the thickness of 2 mm on a built work face, and the inner side of the work face is provided with a steel mesh with the thickness of 2 mm. The type and the specification of the masonry are strictly selected, so that the protective function of a dry stone slope is greatly improved.

Description

technical field [0001] The invention relates to the field of road and bridge construction, in particular to a dry stone slope protection construction method. Background technique [0002] Slope protection refers to various paving and planting on the slope to prevent the slope from being scoured. In the river section where the bridge site is located, the concave bank of the river bank is washed by the water flow year by year, which will cause the river bank to collapse continuously. In order to protect the safety of bridges and embankments, protective buildings must be built on concave banks. In addition, when bridges cause changes in the direction of river water flow, scouring the river bank and endangering farmland and villages and towns, protective buildings must also be built on the river bank. This kind of building is also commonly called revetment. There are direct protection and indirect protection in the form of revetment. Direct protection is to directly reinforc...
