Specific embodiment

In conjunction with accompanying drawing, taking anti-floating construction of specifically meeting an urgent need as a example, this utility model is described further.

First, the number of openings calculating relief hole is reasonably distributed according to actual basement, the quantity of relief hole is that basis is let out The area COMPREHENSIVE CALCULATING in the aperture of pressure hole and aqueduct, estimated peak level and basement determines, through measuring and calculating, the coastal south Generally 600 square metres about settings of one layer of basement one.Pressure release hole number calculates after determining, should be in basement bottom board layer table In the face of it is positioned, typically preferably it is arranged on basement pillar diagonal centre position, relief hole should be put down in basement bottom board layer All it is distributed.Can be spudded in after the completion of positioning relief hole, and its order of spudding in symmetrically is carried out to edge direction for basement zone line, A bench drill machine can sequentially carry out, also can multiple stage rig symmetrically carry out simultaneously.Relief hole is after concrete core drilling rig coring Formed, as shown in figure 1, the diameter general control of relief hole is in 100～150mm, its depth will pass through basement bottom board layer And drill through bed course, then carry brill, pressure release in the hole is slowly withdrawn by the concrete cylindrical block of coring, form relief hole.Relief hole After formation, subsoil water will be gushed, and in emergency circumstances this relief hole plays pressure release level of ground water and recharge basement increases The dual function of load.Whne level of ground water be reduced to basement bottom board layer surface equal when, you can opened with concrete core drilling rig Bore sealing hole.The hole heart alignment of the Kong Xinyu relief hole in sealing hole, both are concentric holes, and the diameter in sealing hole typically should compare pressure release Big more than the 100mm in hole, sealing hole drill hole depth be base plate thickness 1 to two/3rd/, its effect is in relief hole Between form one sealing seam, prevent vertical relief hole after closure, subsoil water directly leaks into ground along the hole wall of relief hole Lower interior.

Aqueduct is buried and the time of sealing of hole flexibly can be grasped according to construction period, flood season situation.During sealing of hole as far as possible Avoid flood season and typhoon weather, subsoil water return to basement bottom board layer surface or following blocked when be optimal.Sealing of hole is Constructed by material fit such as aqueduct, drain pipe, expansion sealing strip or Grouting Pipe, flax silk, leak stopping slurry and expansive concretes Become, wherein aqueduct is to be made with rustless steel or copper pipe material, to prevent tube wall from soaking and corrosion, aqueduct for a long time Caliber should be less more than 50mm than relief hole.Aqueduct upper weld seal ring, prevents subsoil water from penetrating into along diversion tube wall In basement bottom board layer surface, tube wall periphery has the inlet opening of 5～8mm in the 50mm scope of bottom, is beneficial to draining.

Before aqueduct is inserted into relief hole, should first be clogged to relief hole bottom hole with the flax silk group of geotextiles parcel, or directly Connect and be wrapped in aqueduct bottom, be inserted into aqueduct, make the flax silk group press-in that geotextiles are wrapped up to original soil layer (level of ground water Put), this flax silk rolls into a ball the drainage layer as aqueduct, prevents clod from blocking the inlet opening of diversion bottom of the tube.Aqueduct tackles pressure release Hole, the hole heart position in sealing hole, and by outside support, aqueduct is fixed temporarily, prevent aqueduct double swerve.Draw Water pipe upper end is tightly connected valve, then connects drain pipe by valve, makes subsoil water be introduced to underground by aqueduct and drain pipe Carry out pump drainage in the gutter of room or sump, be connected by thread seal or snap joint wherein between valve and drain pipe, Thus facilitating drain pipe to dismantle.Next, flax silk is inserted in layering in space between relief hole and aqueduct, flax silk is made to be filled to At the height of diversion tube wall inlet opening, prevent the flax silk that relief hole top is inserted from blocking draining hole wall.

After aqueduct insertion relief hole, subsoil water can be discharged from the drain pipe of aqueduct and connection；At this moment, concrete is let out The Groundwater pressure of pressure in the hole can reduce, then layered tamping flax silk and closure slurry in the empty wall with aqueduct for the relief hole Body, answers uniform mixing before flax silk and closure slurry filling, after filling in the space between relief hole and aqueduct, is polished with head Reinforcing bar carries out inserting in fact, often fills out one layer and inserts in fact once, till non-leakage.Generally, 100mm left and right thickness slurry is with regard to energy Play stagnant water effect.

After the water outlet of basement pressure release in the hole is blocked, subsoil water is all derived in aqueduct, pressure release in the hole no subsoil water Ooze out.At this moment, pour expansive concrete in sealing in the hole.Before pouring, should bury in the bottom hole edge in sealing hole and expand Sealing rod or Grouting Pipe, to stitch the secondary sealing defence after the first line of defence as subsoil water by sealing, then pour than former The higher leveled expansive concrete of underplate concrete label.Make it should be noted that reserving a breach at the valve of aqueduct when pouring Working place for valve.Treat that the earthing on basement roof is completed by design requirement, and after reaching design strength, you can close The valve of aqueduct, and remove the drain pipe being connected with valve, finally reserved working place expansive concrete at valve Pour closely knit, just complete the process construction of whole float Structure to this.

Above content is intended to technological means of the present utility model are described, not limits technical scope of the present utility model.This Skilled person with reference to existing common knowledge, this utility model is done conspicuously improved, also fall into this utility model protection Within the scope of.
