Execution of special geotechnical work - Diaphragm walls

This European Standard establishes general principles for the execution of diaphragm walls as either retaining walls or cut-off walls. NOTE 1 This standard covers only structures constructed in a trench excavated with a support fluid or in dry conditions, where soil is removed and replaced by concrete or slurry and with wall thickness B ≥ 40 cm. NOTE 2 Diaphragm walls can be permanent or temporary structures. NOTE 3 The following types of structure are considered: a) retaining walls: usually constructed to support the sides of an excavation in the ground. They include: 1) cast in situ concrete diaphragm walls; 2) precast concrete diaphragm walls; 3) reinforced slurry walls; b) cut-off walls: usually constructed to prevent migration of groundwater, clear or polluted, or of other contaminants present in the ground. They include: 1) slurry walls (possibly with membranes or sheet piles); 2) plastic concrete walls. NOTE 4 Walls formed shallow vertical trenches (typically excavations with a ratio of depth over thickness D/B < 5 or D < 5 m) are not covered by this standard.

Eurocode 1 - Actions on structures - Part 4: Silos and tanks

1.1 Scope of EN 1991-4 (1) This document provides rules for calculating actions for the structural design of silos and tanks. NOTE 1 Silos are used for the storage of particulate solids. Tanks are used for the storage of liquids. NOTE 2 For limitations on rules for silos given in this document, see 1.3. NOTE 3 For limitations on rules for tanks given in this document, see 1.4. (2) This document includes some provisions for actions on silo and tank structures that are not only associated with the stored particulate solids or liquids (e.g. the effects of thermal differentials) but substantially affected by them. NOTE Liquid loads on tanks are very precisely defined. Many loads on silos are not known with great precision. This document provides guidance for many practical situations for which very limited certain knowledge is available, and the information is derived from the limited experimental and analytical information available, coupled with conclusions drawn from failure investigations. The information is not based on a sound statistical treatment of experimental data. (3) This document is intended for use with concrete, steel, aluminium, timber and FRP storage structures. NOTE FRP is the standard acronym for fibre reinforced polymer materials. (4) This document is also applicable for the structural assessment of existing silos and tanks, unless otherwise specified by the relevant authority or, if not specified, agreed between the relevant parties for the specific project. NOTE 1 Changes in filling or discharge arrangements, changes in the wall friction of inner surfaces, or in the use of the silo, including storage of different particulate solids, can be reasons for assessing existing silos. NOTE 2 Differentiation of the liquid stored can be a reason for assessing existing tanks. 1.2 Assumptions (1) The assumptions of EN 1990-1 apply. (2) This document is intended to be used in conjunction with EN 1990 1, with the other parts of EN 1991, EN 1992, EN 1993, EN 1995, EN 1997, EN 1998 and EN 1999 where relevant to the design of silos and tanks. 1.3 Limitations on silos 1.3.1 Geometrical limitations (1) The following geometrical limitations apply to the design rules for silos and silo batteries (see 3.2.59 and 3.2.60) covered by this document: - the silo planform cross-section shapes are limited to those shown in Figure 1.1c. NOTE 1 Further information concerning planform cross-section geometries is given in Clause 7. NOTE 2 For the determination of the effective diameter dc of the silo see Figure 1.1c; - the following dimensional limitations on the aspect ratio for free-standing single cell silos hc/dc, the overall height hb and the effective diameter dc apply (see Figure 1.1): hc/dc < 10 (1.1) hb < 100 m (1.2) dc < 60 m (1.3) NOTE 3 See Figure 1.1 for hc, dc and hb. - the structural transition lies in a single horizontal plane (see Figure 1.1a). [Figure 1.1 - Silo forms showing dimensions and pressure notation] (2) Only hoppers that are conical (i.e. axisymmetric), rectangular pyramidal with a/b ≤ 1,5, wedge-shaped (i.e. with two vertical end walls on opposite sides) or oblique are covered by this document. Other hopper shapes and hoppers with internal structures require special considerations. (3) Silos with an oblique conical hopper used to achieve an eccentric outlet are covered by this document. (4) Silos with an oblique hopper are covered, but generally silos with a systematically non-symmetric geometry are not specifically covered by this document. These situations include a chisel hopper (i.e. a wedge hopper beneath a circular cylinder) and hoppers with an elongated outlet other than wedge shaped. 1.3.2 Limitations on the stored particulate solids (1) The following limitations on the stored particulate solids apply to the design rules for silos contained in this document: ...

Chemical disinfectants and antiseptics - Quantitative test method for the evaluation of virucidal activity on nonporous surfaces with mechanical action employing wipes in the medical area (4-field test) - Test method and requirements (phase 2, step 2)

This document specifies a test method and the minimum requirements for virucidal activity of chemical disinfectant products that form a homogeneous, physically stable preparation when diluted with hard water – or in the case of ready-to-use products – with water. This document is applicable to products that are used in the medical area for disinfecting non-porous surfaces including surfaces of medical devices by wiping or mopping – regardless if they are covered by the Medical Device Regulation [1] or not. Due to the new methods of application of surface disinfectants like pre-impregnated wipes this document was established to cover the different application methods. This document is applicable for four methods of application of products for wiping and/or mopping: a) soaking any non-specified wipe or mop with product; b) spraying the product on any non-specified wipe and / or mop or a specified wipe or mop; c) impregnation of specified wipes or mops by the user with the product according to the manufacturer’s recommendation; d) pre-impregnation of specified wipes or mops by the manufacturer as ready-to-use wipes or mops. In all types of application the water control has to be conducted with the standard wipe (5.3.2.17 a), because it is process or method control. The contact time for the water control is no longer than 5 min. This document does not apply to products that are sprayed on or used for flooding of surfaces, without wiping or mopping during the contact time. In this case, the methods of phase 2/ step 2 without mechanical action apply. The test-surface (5.3.2.16) was selected as a standard surface and should cover all non-porous surfaces. It was not intended to cover the influence of each different surface. This document is applicable to areas and situations where disinfection is medically indicated. Such indications occur in patient care, for example: — in hospitals, in community medical facilities and in dental institutions; — in clinics of schools, of kindergartens and of nursing homes; and can occur in the workplace and in the home. It can also include services such as laundries and kitchens supplying products directly for the patients. NOTE This method corresponds to a phase 2, step 2 test. EN 14885 specifies in detail the relationship of the various tests to one another and to “use recommendations”.
