With written permission from City engineer or his Protective system means a method of protecting employees from cave-ins, from material that could fall or roll from an excavation face or into an excavation, or from the collapse of adjacent structures. Protective systems include support systems, sloping and benching systems, shield systems, and other systems that provide the necessary protection. Ramp means an inclined walking or working

Fig. 3 illustrates the order of excavation in the German method)) of tunneling. If the first part, numbered 1 in the figures, is in the top of the tunnel it is called a heading, but if it is at the bottom of the section it is called a drift. The heading or drift being first driven, the full tunnel section is reached by enlarge ment in the order or sequence shown. The usual width of heading is

The nature of the excavation work being undertaken will affect the selection of an excavation method and a safe system of work. Careful consideration should be given to health and safety issues when planning the work where the excavation involves anything other than shallow trenching and small quantities of material. 5.1 Trenching Regulation 306 A person conducting a business or undertaking

Protective systems include support systems, sloping and benching systems, shield systems, and other systems that provide the necessary protection.

Method and procedures for rock blasting works are as follows. Before the commencement of the work, the Engineer will be notified of the areas where rocks are to be blasted. Accordingly, the Engineer will inspect the area for approval before commencement of the works. 6.1 Rock Drilling Rock drilling will be carried out by jack hammer. Hole depth less than or equal 1m, 1 hole /one boulder if

Determining abrasivity for mechanical excavation in hard rock Name: Peter Ellecosta E-Mail: p.ellecostatum.de Supervisor: Prof. Dr. rer. nat. habil. Kurosch Thuro Chair of Engineering Geology Started: 09/2013 ongoing finished Introduction In hard rock TBM drilling, wear issues play a crucial role in the success of a tunneling project. Thus, the prediction of tool life is necessary for the

material. The method of determining the control density is described in Section 5.2. The field density, Line H, is in total wet density units. To compare it to the control density (minus in. (19 mm) dry units) the percentage of plus in. (19 mm) material and the moisture content of the minus in. (19 mm) material must be determined

Trenching and excavation work presents serious hazards to all workers involved. Cave-ins pose the greatest risk and are more likely than some other excavation-related incidents to result in worker fatalities. One cubic yard of soil can weigh as much as a car. Employers must ensure that workers enter trenches only after adequate protections are in place to address cave-in hazards. Other

Face height (H): This is the vertical distance in metres between the top and floor of the bench and should be at least twice the burden (2B). 2 Blasthole diameter (D): Generally, the cost of drilling

SOIL STABILIZATION METHODS AND MATERIALS

Through soil stabilization, unbound materials stabilized with cementican be tious materials (cement, lime, fly ash, bitumen or combination of these). The stabilized soil materials havea higher strength, lower permeability and lower compressibility than the native soil (Keller bronchure 32-01E). The method can be achieved in two ways, namely;

When a tunnel passes through different types of material it is known as mixed face construction. In bored tunneling, the excavation takes place at the portal or at a shaft, thus the is a minimum impact on usual traffic, air noise quality, and utilities. Linings are the most important component of these kind of tunnels. For depths 10 m to 12 m, cut-and-cover is usually more economical and

method for an excavation greater than 20 feet in depth. 9. Employees shall be protected from excavated or other materials or equipment that could pose a hazard by falling or rolling into excavation. Protection shall be provided by placing and keeping such materials or equipment at least 2 feet (.61m) from the edge of the excavation, or a retaining device(s) must be provided. 10. A stairway

This method statement provides the control sequence and installation methodology that will be used for supply, laying and fixing or installation of Stone Flooring (Marble/Granite Flooring), Finishes shown on the approved Shop Drawings or finishing schedules in compliance with the Project Specification.

Where sheets must be installed in hard ground, a dig and drive is usually required to eliminate pile damage and splitting interlocks. Sheet pile will easily cantilever 15 feet and the pile length will be slightly shorter than a soldier pile. Sheet pile shoring advantages: 1. This method provides positive trench wall support. 2. Excavation and

An alternative method of measuring dredging is to measure the volume of dredged material from the hopper or barge in which the material is initially deposited. 2.3 EXCAVATION ANCILLARIES 2.3.1 Trimming of Slopes. Where surface of earthworks are specified to be sloped to a required angle of over 10 degrees to the horizontal, the surface areas of the slopes, given in square meters, are

METHOD OF CONSTRUCTION: For constructing this type this type of foundation; Excavation is done to the required depth. The bottom of the excavation is leveled and compacted; Then the foundation concrete is laid to the required thickness and finished according to the layout of the arches to be constructed under the piers.
