Uses for Marine Mattresses in Coastal Engineering

waves consist of a core covered by one or more underlayers of progressively larger stone, and an armor layer of large stones or concrete armor units. Mattresses could be deployed as an underlayer for some rubble-mound structures. If placed as the layer directly beneath the primary

PDF Alternative Techniques to Riprap Bank Stabilization

waves or moving waters meet unprotected soil, there will always be ero-sion. Covering exposed soil with rock helps protect it from being washed away, securing an embankment against further erosion. Problems arise because the effects of riprap do not stop at the point of installation. When positioned along a section of riverbank, for example,

Tiebacks - Anchored Excavations - DeepExcavation

Excavations with Tiebacks and Rock Anchors - Review Options in DeepEX Software. Anchored walls have become popular in braced excavations because of a) the substantial progress in the technology and availability of high-capacity anchor systems, and b) the absence of interior obstructions that permit uninterrupted earth moving and thus improve the construction conditions of the underground

Everything You Need to Know About Concrete Ceilings | Houzz AU

Concrete ceiling profiles Moving House by Architects EAT has a wave-like concrete roof profile with three vaulted skylights to bring northern sunlight into the open-plan living volume. The roof and ceiling are 'shotcrete', which is mortar or concrete pumped through a hose and sprayed, or pneumatically projected, at high velocity onto a surface or substrate.

Succession in epibenthic communities on artificial reefs

Because of these characteristics, 11 km of cable is unburied and fully protected with nested cast iron half-shells (50 cm long, 15 cm diameter). The cable is also stabilized by 120 concrete mattresses (6 m long, 3 m wide, 40 cm high, Figure 2) installed in 2013, preventing any displacement caused by high hydrodynamic conditions.

Stability of blocks mats under flow conditions

Consequently, the increase of knowledge on the stability of block mattresses is imperative. Main topic, therefore, of this Master Thesis project is the stability of block mats under flow conditions and the research will be done in co-operation with HOLCIM (the major supplier of placed block revetment systems and block mattresses).

Innovative methods for dike construction – An overview

The cast-in-place geotextile mattress was formed by pumping lean concrete into a mold made of geotextile. A picture showing the dike covered by the cast-in-situ concrete mattress is given in Fig. 5. Berms were used to enhance the stability of the dike and to protect the toes of the slopes. The berms were made of crushed stones of 50–80 kg.

Mark Klein Breteler & Krystian W. Pilarczyk Delft

Within the scope of the research on the stability of open slope revetments, much knowledge has been developed about the stability of placed (pitched) stone revetments under wave load and stability of rock under wave and current load. This development of knowledge has lead to a · concrete mattresses; · geosystems, such as sandbags and sand
