Pile Foundation: Suitability, Classification and Construction

(iv) Concreting: After the reinforcement is placed inside the hole, a readily mixed concrete is poured in the hole with the help of funnel placed at the mouth of the hole. Concreting is carried by a technique called tremie-concreting in which concrete is sent down by a pipe to gradually displace the bentonite slurry as shown in the figure 11.24. Get price

Submarine Placing of Concrete by the Tremie

Concrete is continuously fed to the tremie pipe-through a hopper and the pipe is lifted as the concrete level rises. Concrete 1s added continuously until the pour is completed. This method is best applied to concreting in regularly shaped forms. Get price

Bored Piling

The tremie tube (250mm) is withdrawn as concreting proceeds ensuring a minimum concrete head of 2 metres above the top of the tremie tube. Sequence Of Piling The sequence of construction of piles is chosen in such a manner that no damage can be caused to nearby piles still under construction or recently concreted (i.e. less than 3 days).

2016/1/1The tremie pipe is usually marked in metre increments from the toe, and the level of the concrete is dipped from water level with a weighted tape. It is then simple arithmetic to calculate the depth of the tremie in the concrete, but during a long concrete pour, attention has been known to wander! Get price

Underwater Concreting Methods

Underwater concreting using tremie method is convenient for pouring large amount of high flowable concrete. The concrete is moved to the hopper by either pumping, belt conveyer or skips. Tremie pipe, which upper end connected to a hopper and lower end continuously submerged in fresh concrete, is used to place concrete at the exact location from Get price

Underwater Concrete

The end of the delivery pipe must be kept deep enough in the fresh concrete. Another method of placing underwater concrete with minimum loss is the tremie process (Contractor Method). The concrete is placed directly through a 20 – 40 cm diameter pipe into and through the concrete already installed. Get price

Concrete Placement

Concrete should not be cast on a frozen subgrade, and ice must be removed from forms before concreting. Concrete allowed to freeze wet, before or during early curing, may be seriously damaged. Furthermore, temperatures should be kept above 40_F for any appreciable curing (strength gain). Get price

Methods of Transportation of Concrete

Tremie The most common way to use concrete under water is tremie; this is done by tremie pipe. There are 2 retaining walls beside the tremie pipe. This pipe is made piece by piece, and concrete is discharged at the bottom. Only the cement of top surface will Get price

Chapter 3 Pile Construction Sequence

• tremie pipe can be cut minimum 2.0 m in fresh concrete • During concreting the level of the concrete within the pile will be monitored by use of an end weight tape measure. • concrete will be to the working level or minimum 1.0 m above cut-off level • After concreting, the starter casing will be withdrawn by the piling rig 3 Pile Construction • 3.4 Material Specifications 3.4.1 Get price

Tremie Pipe

Tremie pipe remains inside the concrete so that no water enters the pipe from-the-bottom. In other words, the tremie pipe remains plugged at the lower end of the concrete. Again concrete is poured over the funnel and when the whole length of the tremie pipe filled with concrete, the pipe is again slightly lifted and given a slight jerk. Get price

CONSTRUCTION INFORMATION: Work method statement

The tremie pipes are 270mm diameter and are made up of coupled section 0.5m, 1m, 2m, and 3m in length. As the level of concrete in the bored hole rises, the tremie pipe column is raised whilst always ensuring a minimum 2m embedment into the concrete in order to avoid bentonite inclusions. Get price
