In fact; Existing no filler vibroflotation method construction is shaken in closely knit sand pile 1 process; All adopt while promoting and stay the mode of shaking to realize that pile body is compacted, but in the powder fine sand foundation is handled, remove few part pile body (being generally the bigger pile body bottom of overlying burden) can follow powerful shake cave in voluntarily closely knit; The above-mentioned mode of shaking of staying while promoting almost influences the current closely knit effect towards closely knit sand pile 1 of shaking of constructing; That is to say, existing no filler vibroflotation method in the powder fine sand foundation institute's construction molding shake poorly towards the compactness of closely knit sand pile 1, the ground stabilization effect is bad.Thereby, adopt the other mode of shaking of pore-creating in the utility model construction, specifically be to bestir oneself and use to constructing that accomplishing shakes carries out ground extruding towards the pile body of closely knit sand pile 1 through shake side in the pore-creating process of closely knit sand pile 1 of all sides.That is to say that the shaking towards the pile body of closely knit sand pile 1 of accomplishing of constructing in the step 203 is closely knit inadequately, must be through all sides other side that is produced in the pore-creating process of closely knit sand pile 1 that shakes bestir oneself with further reinforcing.
When the utility model will have the construction of no filler vibroflotation method now and shake towards closely knit sand pile 1, its formation of pile adopted stayed the pile mode of shaking to be adjusted into to control vibrating impacter with hoisting velocity V while promoting
CarryThe pile mode that at the uniform velocity upwards promotes is not only controlled easyly, and realizes conveniently, and pile quality is prone to control.
Rely on the roughing sand close consolidated subsoil that comes that shakes owing to shake towards closely knit sand pile 1, thereby sweep stake only fully and handle, could guarantee the compactness at a top.Thereby said shaking behind closely knit sand pile 1 accomplished in construction in the step 203, need in time to current construct to shake sweep stake towards closely knit sand pile 1 and handle, that is to say, respectively shake accomplish towards closely knit sand pile 1 construction after, all must in time sweep a processing.Actually sweep stake and handle, the working procedure control and the technical requirements of each short sand pile 2 are all identical with each item technical requirements of shaking towards closely knit sand pile 1.
Simultaneously, the utility model also need be swept stake and handle in when construction, sweeps stake and handles shaking and in the integral reinforcing of closely knit sand pile 1, play important effect.What is called is swept stake, shakes in the completion of constructing exactly and on the inter-pile soil between the closely knit sand pile 1, sets up a plurality of short sand piles.Sweeping stake can eliminate because of the close effect of shaking not filled and that top foundation soil burden pressure causes for a short time and weaken; Thereby influence is shaken towards the planeness at 1 top of closely knit sand pile and the adverse consequences of compactness, and sweeps and can strengthen the integral reinforcing effect of shaking towards the close sand pile composite foundation.
Find through test; What the utility model adopted shakes towards closely knit sand pile 1; Except that few part pile body (being generally the bigger pile body bottom of overlying burden) can follow powerful vibrations cave in voluntarily closely knit; The backfill of all the other most of pile bodies all is to handle (being that its all side is laid the construction of lacking sand pile) and the peripheral sand that other overflows with current when shaking pore-creating towards closely knit sand pile 1 and recharge and form by sweeping stake.
In the practice of construction process, to a plurality of said shaking when closely knit sand pile 1 is constructed in the step 1, its sequence of construction should be carried out by the campshed method of routine one by one.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of the utility model technical scheme according to the utility model technical spirit.
