Technical Field

The invention relates to a construction process flow, in particular to a rammed earth wall process which can shorten the construction period and is used for repairing an urban wall.

Background

The construction process adopted by the soil-like wall often causes cracks on the soil-like outer wall, the construction process is complex, and the construction time is too long; and cracks appearing outside the soil-imitation wall are generally caused by the fact that the proportion of cement mortar is too large and the maintenance is not timely, so that the color of the whole soil-imitation wall is not uniform, the quality is poor, and the manufactured soil-imitation wall can not meet the requirements of people for the soil-imitation wall gradually.

For the above reasons, a rammed earth wall process capable of shortening the construction period and used for repairing urban walls is a technical problem to be solved urgently by those skilled in the art.

Disclosure of Invention

The invention designs a rammed earth wall process which can shorten the construction period and is used for repairing urban walls, and the rammed earth wall process comprises the following preparation methods,

1. measuring the structure of the pay-off main body, and checking and correcting;

2. 6, perforating and embedding expansion screws 8, and embedding expansion screws 3 groups of the outer side surface of the rammed earth wall transversely up, middle and down at intervals of 60-70 cm, wherein the rammed earth wall is firmly installed;

3. welding reinforcing steel bars, and adopting 6mm cold-drawn reinforcing steel bar spot welding connection;

4. hanging a net, hanging 0.6 x 0.6 wire netting on the side surface of the rammed earth wall, and hanging 1.5 x 1.5 cm electric welding net on the top surface of the rammed earth wall;

5. the cement mortar is used for priming at a ratio of 1:1, the cement mortar is plastic at a ratio of 1:1, and the paint is colored in a manner of imitating the texture of loess.

Further, the wall body in the step (1) has inclined deformity to correct and fill up.

Further, the 6mm cold-drawn steel bar in the step (3) is transversely welded on the expansion screw.

Further, yellow earth texture paint is adopted for spraying in the step (5).

By adopting the technical scheme, the process has the following technical effects that the process manufactured by the technical scheme is used for the preparation of the construction process of the soil-like wall, the process flow can be effectively shortened by adopting the construction process, the prepared soil-like wall is natural, uniform and consistent in color, natural, smooth, firm in material, short in construction time, simple in construction method and suggested to be popularized and used.

Detailed Description

The present invention will be further explained below in order to make the technical means, inventive features, objectives and effects of the present invention easy to understand.

A rammed earth wall process for repairing city wall with short construction period includes the following steps,
