Background technique
Raft plate adds anti-float anchor rod as a kind of common deep basal pit foundation anti-pulling form, using more and more in engineering,
Especially in North China, deep under ground soil layer is mostly sandy silt, clay silt or is flour sand, fine sand, middle sand formation, is
It avoids level of ground water higher and the influence resistance building that building floats is shifted up, it is large-scale used in anti-float anchor rod construction
Machinery has a biggish disturbing influence to base's soil body, a part of soil body must be retained before anti-float anchor rod construction as protection soil layer,
After the completion of anti-float anchor rod construction, then artificial clear slot is taken to clear up reserved soil layer.But current anti-float anchor rod anchorage style
Substantially using bent anchor anchoring and the anchoring of straight anchor, the length and overbending direction strong influence of anti-float anchor rod anchor bar, foundation pit earth
When Fang Zuoye, task difficulty, the operating efficiency of artificial clear slot be low and clear slot earth volume.
Utility model content
The purpose of this utility model is to provide a kind of deep basal pit mechanical anchor anti-float anchor rods, to solve current anti-float anchor rod
Anchorage style uses bent anchor anchoring and the anchoring of straight anchor, the great shadow of length and overbending direction of anti-float anchor rod anchor bar substantially
It rings, when pit earthwork operation, the problem of task difficulty, the operating efficiency of artificial clear slot be low and clear slot earth volume.
To achieve the above object, the utility model provides the following technical solutions: a kind of deep basal pit mechanical anchor anti-float anchor rod,
Including sleeve, Bar Anchorage plate, anti-float anchor rod, concrete raft plate, concrete cushion and soil layer, the upper surface of the soil layer is laid with
Have concrete cushion, be equipped with concrete raft plate above concrete cushion, the inner vertical of the concrete raft plate inserted with
Anti-float anchor rod, and the bottom end of anti-float anchor rod through concrete cushion and extends in soil layer.
Preferably, the top of the anti-float anchor rod is inserted into the inside of concrete raft plate, and the top of anti-float anchor rod passes through
Sleeve is equipped with Bar Anchorage plate.
Preferably, the Bar Anchorage plate is in a circular table shape, and the diameter in Bar Anchorage board bottom portion is greater than Bar Anchorage plate top
The diameter in portion.
Preferably, the thickness of the concrete raft plate is greater than the thickness of concrete cushion.
Preferably, the length of the anti-float anchor rod above the concrete cushion is equal to the anti-float anchor rod below concrete cushion
Length 0.41.
Compared with prior art, the utility model has the beneficial effects that (1) reduces the direct cutting length of reinforcing bar, it is excellent
Steel Reinforcing Bar Material scheme is changed；(2) earth volume for reducing artificial clear slot increases the boundary of works area of mechanical clear slot, relative to curved
Anchor anchorage style solves the difficulty of the clear slot in bent anchor end lower part；(3) the low mark such as catch pit, elevator, tower crane is solved
The problem of eminence anti-float anchor rod Steel Reinforcing Bar Material hardly possible；(4) intensity of anti-float anchor rod anchoring is enhanced, anchoring property is improved, and
Construction is succinct；(5) impermeability of reinforced epoxy anchor pole water-stagnating effect and sole plate, it is long that anchor bar protrudes into sole plate
The reduction of degree reduces infiltration hidden danger.
