  • Precast Concrete Piles: Basic Info | Types | Advantages

    The steel reinforcement in a precast concrete pile is provided to resist the stresses produced due to its handling, driving and loading which the pile is finally expected to receive. These piles are constructed by conventionally reinforcing the concrete with internal reinforcement cage made up of several longitudinal and lateral steel bars and in the form of individual ties or a spiral.

  • Pile foundations

    Special timber that has good durability properties to be used. Please carry the load from the skin friction and end bearing. Constructions in very weak areas where heavy machines cannot be approached, timber piles are used. Screw Piles. The pile is like a screw as indicated in the following figure.

  • Properties Of Concrete

    As most of the structural concrete is reinforced the essential Requirement of good concrete is its ability to provide protection to the embedded steel even in aggressive marine environments. One of the prerequisites to provide protection and to stall the carbonation from reaching the reinforcement in a polluted atmosphere is to ensure good coverage in addition to fixing the limits of chloride level.

    The concrete will be brought up to the working level at least 1.0m above the cut-off level to ensure good quality and contamination free concrete at pile cut-off level. The Bentonite slurry displaced by the concrete will be pumped back to the desander. The concrete above cut-off level will be chipped by the Main Contractor.

  • Sheet Piles: Types, Uses, Advantages & Disadvantages

    The sheet pile serves as a temporary supporting wall that has been driven in a slope or ditch to support soft soil slides from high ground to low ground. Types of sheet piles: 1.Precast Concrete Sheet Pile: This pile is constructed by casting reinforced concrete panel sheets with tongue and groove, a filler joint on the sheet pile ends.

  • Design and Construction of Auger Cast Piles

    The auger is then screwed back down to the original pile tip elevation to establish a small head of grout or concrete on the auger and to achieve a good bearing contact at the pile tip. The grout is pumped continuously under pressure typically up to 150 to 300 psi measured at the top of the auger while the auger is lifted

  • Advantages And Disadvantages of Concrete Piles

    Quality of Concrete Piles. The advantages and disadvantages of the first concrete piles are in terms of quality. Using concrete piles provides more quality than using conventional piles. Precast concrete product materials are sturdier and more high quality when compared to conventional piles.

  • Pads Vs. Concrete Pilings

    Unlike concrete repair methods which can only handle lifting 1 pile at a time, the helical repair method can utilize a unified lift, which could be 10 piles at a time. Once lifted, hydraulic pressure is used to accurately raise a home's foundation and transfer any load-bearing weight to the helical piers.

  • Foundation Construction Checklists

    precast concrete piles by METS. • Check pile lift ring removal and patching requirements per the contract specifications 6. • Verify proper pile length, longer for battered pile. • Mark pile at 1-foot intervals for blow count. • Check pile conditions: crack, rust, rebars on top, etc. • Verify pile layout, batter requirements.

  • Getting Good Concrete| Concrete Construction Magazine

    Pile management. When aggregate is piled, natural segregation occurs. To produce the best concrete, material handlers must work piles so as to deliver uniform gradations and moisture content. Sand. Fine aggregate (sand) is added to a concrete mix to fill the spaces between large aggregate. Fine aggregate is also a blend of several sizes and the most common problems occur when some sizes are missing.

    Cast-in-steel-shell concrete piles are driven pipe piles that are filled with cast-in-place reinforced concrete no deeper than the shell tip elevation. CISS piles provide excellent structural resistance against horizontal loads and are a good option under the following conditions: 1) where poor

  • Bored Pile Foundation Techniques and Benefits

    Bored pile, also called drilled shaft, is a type of reinforced-concrete foundation that supports structures with heavy vertical loads.A bored pile is a cast-in-place concrete pile, meaning the pile is cast on the construction site.This differs from other concrete pile foundations, like spun pile and reinforced concrete square pile foundations, which use precast concrete piles.

  • Square Concrete Pile Steel Molds

    Concrete square pile molds are position fixing is made by radial tongue-and-groove and axial taper pin. Manufactured stage by stage and bound by bolts, at last, the preformed molds are characteristic with the advantages of easy transportation, quick assembling, correct position fixing, good rigidity, and smooth working.
