This Malaysian Standard recommends a code of practice for earthworks forming part of general civil engineering construction.
Section 2 of the code describes methods of designing and constructing cuttings and bulk excavation. It also covers embankments and areas of general regarding in cut and fill for highways, railways and airfields. Certain works such as docks and power stations include both bulk excavation in open ground and deep excavations with supported sides, the latter being dealt with in Section 3 of this code. Where such supported excavations do not represent a large proportion of the total volume of earth moving they will be dealt with mainly in Section 2.
Although site investigations for general purposes are described in BS 5930, the methods of investigation for stability of slopes of cuttings and embankments require additional specialist techniques and equipment which are described in the present code.
Section 3 of the code describes methods of excavating trenches, pits and shafts in various types of ground and methods of forming temporary supports to the sides. Trenches, pits and shafts are excavated to enable some form of permanent construction to be founded at the level of the bottom of the excavation and any permanent support to the ground faces to be formed.
Temporary supports referred to throughout the code are taken to include alternative materials such as timber, steel and reinforced concrete, and alternative methods such as timbering, trench sheeting, sheet piling, diaphragm walls and contiguous bored piled walls.
Figures 21 to 35 are published to illustrate specific technical requirements referred to in
Section 3; they are not intended to show all details or to prescribe the design in any other respect. Timber has been shown in some of these figures because it is the traditional material, but this does not preclude the use of other materials which may be found more expedient (see 3.2.1). Any members omitted (e.g. puncheons, tipping pieces, lacings, ground props) are to be provided where necessary.
