10、O (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical co
11、mmittee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electro
12、technical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the me
13、mber bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identif

24、onveyor: an endless belt or auger used to elevate concrete mix into a mould or to place it near the center of a pavement; diverter plough: a pusher-blade type device used to transfer material from side to side. NOTE 2 In some designs, the concrete mix may be delivered to a hopper without transverse
25、distribution. 2.6 reinforcement guide set of supports whose role is to position the longitudinal reinforcements within the zone where the concrete mix is plastic NOTE The reinforcement guide is commonly referred to as rebar flute or flutes. 2.7 front metering strike-off device comprising generally a
26、 vertically sliding plate, intended for regulating the concrete mix height within the grout box to a specific depth 2.8 vibration zone zone located perpendicular to the vibration device and within which the concrete mix is in the plastic state, i.e., suitable for slipforming 2.9 distance of vibratio
27、n maximum distance in a given direction where the action of the vibration is effective NOTE For internal vibration devices in general, action distance within the concrete mix is referred to (commonly referred to as the “radius of vibration”). 2.10 final finisher plate placed at the rear of the machi
28、ne, independent of the mould, which rests on the existing construction work with a view to providing secondary finishing of the concrete surface NOTE The device may be used as an attachment for execution of concrete surfaces. It may be static or dynamic. 2.11 slope controller cross-slope sensor, whi
29、ch makes it possible to give a specific slope to the machine performing the construction work to be executed, irrespective of the slope of the support over which the machine moves NOTE This device can be considered an accessory or attachment item on pavers to measure cross slope and mechanically con

33、ration device mounted in front of the mould to facilitate uniform compaction of the extrusion process 3 Operating principle Slipform pavers use the properties specific to concrete and in particular its ability to become fluid when submitted to vibration; to regain its consistency when forced through
34、 the extrusion process and no longer submitted to vibration. The principle of the slipform paver is to use the time the concrete mix is in a plastic condition in order to mould it to the desired shape, by appropriate extrusion-type mould and applied energy. 4 Description of a slipform paver 4.1 Basi
35、c unit A slipform comprises a self-propelled frame on which are installed the following: a device to distribute the concrete mix within the confines of the mould; a vibration system used for compaction of the concrete mix when in the plastic state as it is being moulded; a mould, which defines the s
36、haping of the concrete; a sensor control system for control of steering (alignment), and elevation (grade) from known references; a control console and operators station; a power unit. Depending on the type of work to be executed (drainage structures, road safety structures and pavements), the base
37、machine is equipped with additional devices. ISO 16039:2004(E) 4 ISO 2004 All rights reserved4.2 Device for execution of drainage structures For execution of drainage structures (edgings, gutters and so on), the slipform paver is supplemented by a device which regulates the delivery of the material
38、within the vibration zone and mould (screw feeder, belt conveyor). 4.3 Devices for execution of road-safety structures For these construction works (barriers, walls etc.), the slipform paver may include the following equipment: a device which regulates the delivery of the material (screw feeder, bel
39、t conveyor); a mould supply hopper (via its upper part); at least two internal vibrators; a slipform mould; a slope controller which enables the maintenance of the machines slope attitude while advancing. The mould, depending on the machine design, may be mounted on the left-hand or right-hand side
40、of the machine frame or underneath this frame. NOTE Some machines can be operated without a slope controller in certain applications. 4.4 Equipment of slipform pavers for execution of roadways, airfields, and other large pavement structures 4.4.1 Basic equipment For these construction works, the sli
41、pform paver includes the following equipment: a spreading device or transverse distributor, either auger screw or diverter plough, to spread the material laterally in front of the paving mould; a vibrating device. The vibrating device is a set of internal vibrators spread out regularly over the whol
42、e width of the construction work. The position of the internal vibrators in the vertical plane is adjustable and is determined as a function of the material to be placed and the layer thickness to be produced; a mould with side forms in order to produce the appropriate width pavement; a sensor contr
43、ol system for control of steering (alignment) and for control of elevation (grade) from known references. 4.4.2 Other equipment Depending on the specific cases, the following equipment allows execution of the various paving operations: dowel-bar inserter, tie-bar inserter, internal vibrator and fina
44、l finisher. 5 Adjustable parameters on a slipform paver Certain machine parameters can be adjusted in order to take into account the special characteristics of the concrete and of the shape of the construction work. These are as follows: the position of the vibration device in relation to the mould,
45、 in order to prevent the air which escapes from the concrete mix becoming “trapped” beneath the mould; ISO 16039:2004(E) ISO 2004 All rights reserved 5 the vibration force (frequency setting), so that the concrete mix is subjected to vibration at the front part of the mould with the underneath rear
46、part of this mould being vibration-free; the rate of supply of the concrete mix to take into account, for example, the machine-advancement speed; the guiding system sensitivity, in particular to meet the requirements for smoothness specified for the construction work. 6 Commercial specifications 6.1
