Secant Pile

Secant Pile refers to the use of mechanical grinding holes, casing under pressure, grab the casing soil, between the pile and the pile foundation pit structure arranged in bite-shaped
 
Style. The arrangement of the pile is generally an a pile (plain concrete piles) and a b piles (reinforced concrete piles) spaced, construction of the first construction of a pile after pile construction b, a pile of concrete using ultra retarding concrete, requests must be completed before the initial setting of a pile of concrete piles b.
Construction points are as follows:
(A) for concrete guide wall, dental x ray unit ensuring accurate positioning bite pile to ensure a smooth rig to withstand construction loads.
(2) drilling, dipping first one casing, casing vertical control, using inclinometer casing affixed to the outer wall of the vertical degree detection, detection of deviations promptly corrected. After the casing into the hole with concrete pouring piecewise uprooted.
(3) pouring of concrete, the B Pile A pile due to cutting, the A concrete pile does not reach a state where the strength of the sleeve under the rig cutting grinding action and generates the A concrete pile damage. To this end, the use of anti-A pile of concrete setting time, the A pile of concrete at the end of the initial setting state applied for B-pile construction program. According to tests, retarding superplasticizer SP-type doped after the initial setting time of concrete around can delay to 60h (according to the situation of construction equipment and construction speed determination), ensuring the implementation of the construction program operability. Concrete using catheter infusion, if the hole bottom seepage much water inflow exceeds l m3 / h, using underwater concrete pouring.
