The support pile that support pile and two rows extend along Damping ditch width;
Being provided with a circle cement mixing pile outside this circle support pile, at the bottom of the stake of cement mixing pile, absolute altitude is than the bottom of trench absolute altitude of Damping ditch
It is low more than 1 meter,
Set, at interval of 4~6 meters, the top inner support extended together along Damping ditch width at capping beam absolute altitude, and in supporting
The middle part inner support extended along Damping ditch width, inner support in the middle part of adjacent two it is provided with at the absolute altitude of the half degree of depth of stake
Interval be also 4~6 meters;
The inner side expanded screw connection often arranging the support pile extended along its length has the shockproof plate of at least one of which;In Damping ditch
Fill up foam.
The method of construction this utility model Damping ditch is: first accomplish fluently a circle cement mixing method as water-stop curtain, then edge
The profile form construction one circle support pile with cast-in-situ bored pile of Damping ditch, then bear down on one at the stake top of support pile construction one circle
Beam is to connect into entirety by each support pile of circle, then pours top inner support at capping beam absolute altitude, excavates downwards
Damping ditch, digs inner support in the middle part of the half after-pouring of the support pile degree of depth, is further continued for down digging bottom of trench absolute altitude, subsequently often
Arrange and fix shockproof plate with setscrew inside the support pile of Damping ditch length direction extension, finally with foam, Damping ditch is filled out
Full.
Use the Damping ditch of band support system of above structure compared with prior art, have the following advantages.
One, laid a circle cement mixing method outside this Damping ditch, formed water-stop curtain, prevented the water of outside from penetrating into and subtract
In shake ditch, so, on the premise of having completely cut off outside water inlet, the water within Damping ditch can quickly ooze from bottom of trench, and this is just
Avoiding Damping ditch hydrops, the compressional wave hydrops in Damping ditch having blocked vibration is outwards propagated, thus improve damping and every
Shake effect;Two, each support pile of this Damping ditch, capping beam, top inner support and middle part inner support together constitute whole
The support system of body formula, therefore the Damping ditch of band support system of gaining the name, this integral support system can effectively support the side of the soil body
Pressure, it is to avoid cave in, therefore its degree of depth can significantly increase, it is ensured that the degree of depth of Damping ditch reaches to be protected target such as building
More than the twice of thing underground foundation and depth of underground pipelines, further ensure that damping and the isolating affection of protected object;Three,
The inner side of the support pile laid along its length of each row is respectively and fixedly provided with one layer of shockproof plate to two-layer, and shockproof plate is to vibration
Compressional wave have reflection, decrease to by protection targeted propagation compressional wave, further enhance damping and isolating affection;
Four, Damping ditch is filled with foam, and compressional wave is played irreflexive effect by foam so that originally neat the most uniformly towards
It is dispersed into the vibration to the irregular propagation of all directions by the vibration of protection targeted propagation, further reduces to being protected
The vibration of targeted propagation, further improves damping and isolating affection, and the material of foam own is cheap, and cost is the lowest;
Five, after pile foundation construction completes, each shockproof plate can be reclaimed and use for following cycle, reduce cost, good economy performance.
