Execution of special geotechnical work - Grouting

Execution of special geotechnical work - Grouting

This standard is applicable to the execution, testing and monitoring of geotechnical grouting work. Specific aspects concerning design are provided since ENV 1997-4 has been abandoned. Grouting for geotechnical purposes (geotechnical grouting) is a process in which the remote placement of a pumpable material in the ground is indirectly controlled by adjusting its rheological characteristics and by the
manipulation of the placement parameters (pressure, volume and the flow rate). The following principles and methods of geotechnical grouting are covered by this standard : - displacement grouting (compaction grouting, hydraulic fracturing) ; - grouting without displacement of the host material (permeation, fissure grouting, bulk filling). Specialised grouting activities, generally associated with structural and/or emergency works, are not covered by this standard.

Ausführung von besonderen geotechnischen Arbeiten (Spezialtiefbau) - Injektionen

Diese Norm ist auf Ausführung, Prüfung und Überwachung geotechnischer Injektionsarbeiten anwendbar. Da ENV 1997-4 aufgegeben wurde, werden bestimmte Planungsaspekte miterfaßt. Die Injektion mit geotechnischer Zielsetzung (geotechnische Injektion) ist ein Vorgang, bei dem die Einbringung eines pumpbaren Materials in den Baugrund indirekt kontrolliert wird, indem die rheologischen Kennwerte des Materials entsprechend angepaßt und die Einbringungsparameter (Druck, Volumen und Durchflußrate) gesteuert werden.
Folgende Prinzipien und Verfahren der geotechnischen Injektionen werden in dieser Norm behandelt: - Injektionen mit Baugrundverdrängung (Verdichtungsinjektion, hydraulische Aufbrechinjektion) ; - Injektion ohne Baugrundverdrängung (Poreninjektion, Kluftinjektion, Hohlraumverfüllung). Spezielle Injektionsanwendungen, welche allgemein mit Bauarbeiten verbunden sind, oder welche aus Katastrophenfällen resultieren, werden in dieser Norm nicht erfaßt.

Exécution des travaux géotechniques spéciaux - Injection

La présente norme s'applique à l'exécution, aux essais et au contrôle de travaux d'injection. Par suite de l'abandon de l'ENV 1997-4, certains points particuliers relatifs à la conception sont traités ici. L'injection à des fins géotechniques (injection géotechnique) est un procédé qui consiste à introduire à distance dans le terrain un matériau pouvant être pompé, la maîtrise en étant assurée indirectement en ajustant les caractéristiques rhéologiques du fluide pompé et en intervenant sur les paramètres de mise en place (pression, volume et débit). La présente norme s'applique aux principes et méthodes d'injection géotechnique suivants : - injection avec déplacement des terrains (injection solide, fracturation hydraulique) ; - injection sans déplacement des terrains (imprégnation, injection de fissure, injection de comblement). La présente norme ne s'applique pas aux travaux d'injection particuliers, qui sont en général associés aux travaux
effectués sur des structures, ou en urgence.

Execution of special geotechnical work - Grouting
SIST EN 12715:2021

This document is applicable to the execution, testing and monitoring of geotechnical grouting work.
Grouting for geotechnical purposes (geotechnical grouting) is a process in which the remote placement of a pumpable material in the ground is indirectly controlled by adjusting its rheological characteristics and by the manipulation of the placement parameters (pressure, volume and the flow rate).
The following principles and methods of geotechnical grouting are covered by this document:
-   displacement grouting (compaction and compensation grouting);
-   grouting without displacement of the host material (permeation, fissure/contact grouting, bulk filling).
Figure 1 illustrates the various injection methods associated with these two principles.
NOTE   The term consolidation grouting is sometimes used to emphasize an improvement in the strength or deformation characteristics of a soil or rock mass, with the aim that it does not undergo any unacceptable deformation. The term compensation grouting is used when the objective of grouting is to concurrently compensate for ground loss.
The principal objectives of geotechnical grouting are:
-   the modification of the hydraulic/hydrogeological characteristics of the ground;
-   the modification of the mechanical properties of the ground;
-   the filling of natural cavities, mine workings, voids adjacent to structures;
-   inducing displacement to compensate for ground loss or to stabilize and lift footings, slabs and pavements.
Specialized grouting activities, generally associated with structural and/or emergency works, are not covered by this document.
The execution, testing and monitoring of jet grouting work is not covered by this document and is covered by EN 12716.

SIST EN 1536:2011+A1:2015

1.1   This European Standard establishes general principles for the execution of bored piles (see 3.2).
NOTE 1   This standard covers piles or barrettes which are formed in the ground by excavation and are structural members used to transfer actions and/or limit deformations.
NOTE 2   This standard covers piles with circular cross-section (see Figures 1 and A.1a)) and barrettes (see 3.3) with rectangular, T or L or any other similar cross-section (see Figure 2) concreted in a single operation.
NOTE 3   In the standard the term pile is used for circular cross-section structure and the term barrette for other shapes. Both are bored piles.
1.2    This European Standard applies to bored piles (see Figure 3) with:
-   uniform cross-section (straight shaft);
-   telescopically changing shaft dimensions;
-   excavated base enlargements; or
-   excavated shaft enlargements.
NOTE    The shape of a pile base and of an enlargement depends on the tool used for the excavation.
1.3    This European Standard applies (see Note) to:
-   bored piles with a depth to width ratio  5;
-   piles (see Figures 1 and 3) with a shaft diameter 0,3 m  D  3,0 m;
-   barrettes (see Figure 2) with the least dimension Wi  0,4 m, a ratio LBiB / Wi between its largest and its least dimensions  6 and a cross-sectional area A  15 m²;
-   piles with circular precast elements used as structural member (see Figure 7) with a least dimension DP  0,3 m;
-   barrettes with rectangular precast elements used as structural member with a least dimension WP  0,3 m.
NOTE   The standard covers a large range of diameters. For small diameter bored piles less than 450 mm, the general specification can be adapted to cater for the lack of space (e.g. minimum bars number and spacing).
1.4    This European Standard applies to piles with the following rake (see Figure 4):
-   n  4 (  76°);
-   n  3 (  72°) for permanently cased piles.

EN 15237:2007(Main)
Execution of special geotechnical works - Vertical drainage
SIST EN 15237:2007

This European Standard establishes general principles for the execution, testing, supervision and monitoring of vertical drain projects.
This European Standard includes the application of prefabricated vertical drains and sand drains and deals with requirements to be placed on design, drain material and installation methods. This European Standard applies to the improvement of low-permeability, highly compressible soils by vertical drainage and preloading. Information regarding loading (embankment, vacuum or ground water lowering) and preloading is given in informative Annexes A and B.
Vertical drainage is used both in on land and in marine constructions for the following purposes:
   (pre-)consolidation and reduction of post-construction settlements;
   speeding up the consolidation process by decreasing the path lengths for pore water dissipation;
   increase of stability (by increasing effective stresses in the soil);
   groundwater lowering;
   mitigation of liquefaction effects.
In each case there is an overall treatment of the soil (the volume of the drains is small in relation to the soil volume treated).
This European Standard does not include soil improvement by means of wells, gravel and stone columns, large-diameter geotextile enclosed columns or reinforcing elements.
Vertical drainage can also be combined with other foundation or ground improvement methods, e.g. electro osmosis, piles and compacted sand piles, dynamic compaction and deep mixing.
Guidance on practical aspects of vertical drainage, such as investigation of drain properties, execution procedures and equipment, is given in Annex A. Investigation of soil characteristics and assessment of design parameters, which are affected by drain properties and execution, are presented in Annex B.
