Description

A kind of Damping ditch

Technical field

The utility model relates to the shockproof field of ground construction, is especially job site and week when one carries out pile foundation construction Surrounding environment separates to realize the Damping ditch of damping or shockproof function.

Background technology

When carrying out pile foundation construction, tamp the soil body, use jump bit chopped cooked entrails of sheep rock stratum, crane and concrete tank entrucking in construction ground During face traveling etc., all inevitably produce vibration.This vibration is understood from job site to surrounding enviroment Spreading and diffusion, Shake loose the periphery soil body so that periphery soil body generation differential settlement.This differential settlement can cause surrounding building to occur Tilt, or cause the underground utilities being embedded in the periphery soil body that the rupture failure of rigidity occurs, affect periphery pipeline and periphery The normal use of building.And, the connecting portion of the underground piping of some major projects such as gas piping is that employing is gluing Linking together, vibration can make the bonding part of above-mentioned pipeline occur to loosen, and causes pipe leakage so that pipeline cannot Normal use, and pollute environment, cause potential safety hazard.

The impact that surrounding building and pipeline are caused by the vibration producing to reduce pile foundation construction, typically can be in construction site And the Damping ditch of certain depth and one fixed width is set between the protected target of periphery.Its Normal practice breaks two row's steel exactly Sheet pile, then hollow out certain depth in centre；Or only play row's steel sheet pile, ditching back-up sand；Even do not beat steel sheet pile, only Ditching back-up sand, What is more, and a ditching sand is not filled out.

The Damping ditch of above-mentioned prior art suffers from the drawback that the first, easy ponding in ditch, and the compressional wave vibrating generation is energy By liquid transmissive, after ditch ponding, naturally do not have the effect of damping or shock insulation；2nd, above-mentioned Damping ditch props up without inside Support body system, that digs is too deep it is possible to cause and cave in, and if damping to be played or isolating affection often require that the degree of depth of ditch reaches To by protection more than 2 times of the object degree of depth, the trench depth of prior art is limited, does not objectively reach damping, shock insulation Require；3rd, above-mentioned Damping ditch internal structure is excessively simple, only hollows out a groove, by the air in groove or back-up sand damping, And the compressional wave vibrating can be propagated by gas, liquid and solid, therefore the Damping ditch effect of prior art is inconspicuous, and damping is imitated Fruit is very undesirable；4th, outwards propagate the approach of vibration from job site and also have one, i.e. job site and surrounding building, The lower section of underground utilities there is also underground water, and the compressional wave of vibration outwards can be propagated for medium with water along ground water regime, by Very low in this position, route of transmission, therefore this partial vibration is difficult to cut down and isolate.

Utility model content

The technical problems to be solved in the utility model is to provide and is avoided that ditch internal water accumulation, can increase substantially the degree of depth, can make Obtain damping and isolating affection preferably a kind of Damping ditch.

Technical solution of the present utility model is to provide a kind of Damping ditch, and it includes a circle ground-connecting-wall, this circle ground-connecting-wall Including the ground-connecting-wall that the ground-connecting-wall that extends along Damping ditch length direction of two rows and two rows extend along Damping ditch width, ground Even the bottom degree of depth of wall exceedes the degree of depth of Damping ditch；

It is provided with the middle part inner support extending along Damping ditch width, adjacent two at the absolute altitude of the half degree of depth of ground-connecting-wall The interval of middle part inner support is also 4～6 meters；

The expanded screw in inner side of the ground-connecting-wall that row of close job site extends along its length is connected with at least one of which Shockproof plate；

The bottom of trench of Damping ditch is also plugged with relief tube, lower more than 1 meter than bottom Damping ditch bottom relief tube, relief tube top Being provided with outside elbow, elbow is above the ground level；Foam is filled up in Damping ditch.

The method of construction the utility model Damping ditch is: first accomplishes fluently the profile as Damping ditch for the circle ground-connecting-wall, then digs down Until reaching the half of the ground-connecting-wall degree of depth, pouring middle part inner support concrete, then digging bottom of trench down always, subsequently close Fix shockproof plate with setscrew inside the ground-connecting-wall that row of job site extends along Damping ditch length direction, then will let out Pressure pipe is inserted bottom Damping ditch, finally, inserts foam by Damping ditch.

Use a kind of Damping ditch of above structure compared with prior art, have the following advantages.

First, laid a circle ground-connecting-wall outside this Damping ditch, played the effect of 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 Avoid Damping ditch ponding, blocked vibration compressional wave outwards propagate through the ponding in Damping ditch, thus improve damping and every Shake effect；2nd, a circle ground-connecting-wall and the middle part inner support of this Damping ditch together constitutes all-in-one-piece support system, and this is whole Body formula support system can effectively support the lateral pressure of the soil body, it is to avoid caves in, therefore its degree of depth can significantly increase, it is ensured that subtracts The degree of depth of shake ditch reaches to be protected more than the twice of target such as building underground foundation and depth of underground pipelines, further ensures that The damping of protected object and isolating affection；3rd, on the ground laid along its length of that row near job site even The inner side of wall is respectively and fixedly provided with one layer of shockproof plate to two-layer, and the compressional wave to vibration for the shockproof plate has reflex, decreases to quilt The compressional wave of protection targeted propagation, further enhances damping and isolating affection；4th, it is filled with foam in Damping ditch, and steep Compressional wave is played irreflexive effect by foam so that be originally neatly dispersed into towards by the vibration of protection targeted propagation uniformly To the vibration of the irregular propagation of all directions, further decrease to the vibration by protection targeted propagation, again further Improve damping and isolating affection, and the material of foam own being cheap, cost is also low；5th, when vibration is through ground water regime When outwards propagating, upwards can release from relief tube with underground water, so, prior art cannot eliminate along underground water This partial vibration to protection targeted propagation is just released, therefore also further improves damping and isolating affection, and And, the water that relief tube is discharged can flow to the outside of a circle ground-connecting-wall of Damping ditch along elbow, is not detained in ditch, no Damping and isolating affection can be reduced.
