Description
Technical field
The utility model belongs to anchoring engineering technical field, and in particular to a kind of from draining string data enlarging anchor rod supporting knot
Structure.
Background technology
With the fast development of China's economy, skyscraper and city underground engineering are on the increase, and are generated therefrom big
Measure deep pit digging support engineering.With the increasing of foundation ditch scale and depth, engineering accident and construction difficult problem gradually increase, especially
In China's Coastal Areas, soft soil layer is widely distributed, and soil moisture content is high, physico-mechanical properties is poor so that deep basal pit stability
Contradiction between anchorage technology becomes very urgent and protruded.Grouted anchor bar is difficult to weak soil used by traditional anchorage technology
The characteristics of side slope provides preferable anchoring effect, and enlarged footing anchor pole relies on itself high-bearing capacity is promoted in soft clay area should
With.At present, it is high-pressure injection enlarging anchor rod using more enlarged footing anchor pole in Deep Foundation Pit Supporting Project, but in soft clay area
In deep-foundation pit engineering, it is controllable difficult pore-forming, anchoring section injecting cement paste compression strength deficiency, construction quality to be present in high-pressure injection enlarging anchor rod
A series of problems, such as property difference.However, the improvement for weak slope should not be limited to improve supporting construction bearing capacity, soil is improved
The same significant of mechanics characteristic, Deep Foundation Pit Dewatering Design are one of key issues that emphasis considers before foundation pit construction, are to carry
The effective measures of high soil body mechanical strength.Therefore, it will be enlarged by an anchorage technology to be combined with water discharge technology, be a kind of deep base of raising
Cheat the more effective supporting measure of engineering stability.
Application No. 201420805558.2, entitled draining is compound to be disclosed from the patent for boring tire string data suspension roof support structure
A kind of method for protecting support for being combined drainage measure with enlarged footing anchorage technology, it is characterized in that from tire string data anchor pole is bored by hollow

The manufacturing process of string data anchor pole is more complicated, and drain bar is larger to domatic disturbance during arranging, and easily causes domatic soil
Body collapses, in addition, the draining provided in the supporting is new is separate with supporting measure, increases difficulty of construction and input.
Water swelling rubber technology is a kind of the new of hydrophilic radical or hydrophilic component to be introduced in the elastic matrix of rubber
Type technology, upon contact with water, hydrone can enter in matrix, and extremely strong affinity is formed with the hydrophilic radical in rubber,
And the hydroaropic substance in rubber is dissolved or is swelled, permeable pressure head is formed inside and outside rubber, this pressure difference promotes water to rubber
Internal penetration.Hydroaropic substance constantly absorbs moisture, causes rubber to deform upon.Water swelling rubber meets water and is expandable to itself
Quality or the several times of volume or even hundreds times, adapt to malformation, and produce the larger bulbs of pressure, are keeping the elasticity of matrix
While with intensity, the also ability with water conservation sealing.Water swelling rubber technology is incorporated into enlarged footing anchor by the utility model
Gu in technology, and combine drainage anchor rod technology and propose a kind of deep basal pit from draining string data enlarging anchor rod supporting construction and construction party
Method.
