hey all steemit friends

today I want to share knowledge science and shering with my very limited ability and still very less my knowledge when compared with them that is an engineer far more powerful than me,

please a understand a little about the basic theory of the foundation of the retaining wall that is done by the a work of installing human labor, as for the human work which is technically ordinary workers, trained workers, skilled and trained workers and inspectors are added with some materials for work foundations of retaining walls soil , such as river rocks or mountain rocks, sement portlad, clean sand for couples soil, clean water and pebbles for concrete foundry work under the foundation, because each of these works is not done by origin but by guidance and the rules that apply to each of these jobs.

The a foundation of a retaining wall is a retaining wall construction which prevents landslides caused by a not solid or natural soil and prevents and retains from ground collapse on the slope or slope of the soil with no stability and its ability can not be guaranteed by the slope of the soil itself. If the retained soil will provide an active impulse to the retaining wall structure then the structure will be more likely to reverse or shift.

of the above definition of the retaining wall is also a useful building and serves to improve the level of soil stability and soil conditions. In general, retaining walls are made of soil a walls, masonry or pairs of rocks for retaining walls and some are made of wood in ancient times but they are not used anymore.

The following are some categories of retaining soil walls:

1. If the retaining wall is made of cast concrete it is very good because by the way we transmit it with concrete mortar of course the quality of its concrete will be strong and can last long.
1. If the retaining wall is done by installing with rocks and reinforced by sand and cement, and by mounting with mountain rocks this pair can also be categorized very well this is similar to concrete cast method this is very often done in the field of work, this retaining wall by way of stone installation Kali or mountain stone with well arranged and neatly done pair, this retaining wall after working on it and the stone installers that have been completed then the surface wall should be in plaster with a factor cement or mortar, then its strength is also very strong. But this percentage is under the retaining wall by means of concrete cast because the concrete mix is very good,
1. if the retaining wall soil a using materials of wood material and board is called by technical term that is TURAB. This can be done directly in place to be made and can be elsewhere and after it is taken to the location and directly in the pairs, Turab has been very rarely used again in the world of civil engineering work, because this construction can not survive because of factors made of wood and board.

This retaining wall works is built primarily in areas where the soil is still unstable. Most retaining soil wallsare made of cast concrete with mortar, clean sand and gravel and retaining walls reinforced with a mixture of cement, sand, gravel and water. In addition, the material in adding raw materials to make this construction can also come from raw materials mortar, concrete, wood, and so forth.

Below I will explain some basic techniques of retaining wall at the location where I work.

this photo is a zero photo of initial condition before work done, in this work first have to do the installation of wood and yarn on bowplank installation job, so that at the time of doing the next job will be easier and lead to reference from work drawing.

below there are drawings of work in a technical and more understanding for the field work guidelines.

Image is technically work

below there is little understanding of work items and volume of each type for work items.......from the drawing beside this for the excavation work of the soil with its large volume with the cross-sectional area for soil excavation (L = 3.1 M2) and with length (P = 150 M ') so the volume for soil excavation is ( Volume = 465 M3 ).

photos and Images are in the works

this photo shows the activity of the working conditions being done, this installation of river rocks for retaining walls and by following the bowplank guidelines

this condition of job stages is still being done and almost about 75% realization of progress of work, because every day his job progress increases

below there is little that I will make in the form of tables about the type of work and volume of work.

Description of job type	Volume	Unit
a.Bowplank Wood Work	1.0	Ls
b.Land excavation work	465	M3
c.The work of the river rock couples with mortar cement	495	M3
d.Closing work Cement plaster 1: 2	675	M2
e.pekerjaan landfill tanah	104	M3

this photo shows the stages of progress of work progress 95% with some other work items that have not done and that will be done, such as the last stage work and cleaning of the final field work.

this is a technical drawing for the front side of the retaining wall

so many thanks and hope to be useful for everyone, if there are many mistakes in this writing please forgive.
