Abstract

The present invention relates to a deviation correction method of an inclined building on a soft soil foundation, which comprises the following steps that firstly, a foundation plate surface or a position on the side surface of a panel on one inclined and opposite side of a building is drilled, a jetting device is inserted into the drill hole so that pressure water rushes at a soil body on one side which needs deviation correction on the building through the jetting device, and at the moment, mud wells up to a hole opening and flows into a gutter and a settling pond connected with the hole opening. The jetting device is continuously moved so that the jetting device flushes water to the soil body on one side which needs deviation correction in the mode of subsection, delamination and multidirection from top to bottom or from bottom to top, the mud is continuously driven to well up to the hole opening, and is overflowed to the gutter and the settling pond, flush and soil removal are continuously carried out so that the soil body continuously creeps, flows and is disturbed until the building is strengthened and deviation is corrected gradually. The present invention is particularly suitable for being used in sludgy soil.

Description

A kind of straightening method of inclined building on soft soil foundation

The present invention relates to a kind of method for correcting error to inclined building, particularly to the inclined building on the soft foundation, opposite side in its inclination is holed, and the straightening method of segmentation, layering, multidirectional a kind of inclined building on soft soil foundation of soil body stamping press water being rectified a deviation by boring jetting device.

For all kinds of buildings, since the ground problem, time long back building regular meeting run-off the straight; the harm user security, building collapsing also can take place in severe patient, causes bigger economic loss and personnel casualty accidents; be head it off, the patent of relevant inclined building method for correcting error is also arisen at the historic moment.

It is a kind of with boring vertical shaft and beat jet orifice, return port on the borehole wall that the patent No. 94105917.0 " method for correcting error of inclined building and isolated plant thereof " just provides, to the jet orifice jetting, and mud flows back in the drilling well, again with slush pump with the mud in the well discharge in the outer precipitation well of well, water in the precipitation well returns in the pond and can recycle repeatedly, the earth fall is fallen and building is returned incline to sinking till building obtains correction fully.

Needing to build up internal diameter with brick or concrete in the correction process is that the Vertical Well of 80～100cm is a plurality of, and seal the shaft bottom with concrete, (by the direction of correction design appointment) opens the jetting hole on the borehole wall, backwater hole is offered in below, jetting hole, also need use the slush pump slurry-sucking, construction building material cost height, the operator need descend in the underground vertical shaft facing to the construction of jetting hole, dangerous, dangerous, execution conditions are also poor.

The object of the present invention is to provide a kind of straightening method of inclined building on soft soil foundation, its method for correcting error is simpler, operation is easier, the operator need not descend underground construction, improved condition of labor, easy construction, safety, reliable, and construction building material cost cost is lower.

The step 1. that the present invention is achieved in that straightening method is at first in the foundation slab face or the boring of panel side of the opposite side of building inclination; 2. the jetting device is inserted in the boring, make press water rush at the side soil body of the required correction of building, at this moment be rushed to the aperture on the mud, and flow into connected gutter, sedimentation basin by the jetting device; 3. segmentation, layering, from top to bottom multidirectional or from top to bottom, continuous mobile jetting device makes its side soil body bath to required correction, constantly drive on the mud and be rushed to the aperture, excessive again bath more than gutter, sedimentation basin repeat, casting constantly are disturbed the soil body and produce creep, rheology, till building is progressively set upright, rectified a deviation.

Fig. 1. job site of the present invention layout.

Fig. 2. segmentation of the present invention, construction in layer view.

Earlier pull side and be drilled to the round footpath at 6～40cm at the foundation slab face of the opposite side of building inclination or face, 40cm, the vertical drilling of hole depth 150～1000cm (1) or inclined hole, substrate center of gravity one side of building is stretched in the bottom of inclined hole, aperture, pitch-row do not make the passage that forms connection between the pipe of hole be as the criterion again to help operation, casting.

Because of the upper strata of ground mostly is fragment, its infiltration power of hardcore bed is strong, for outwards not overflowed in other hole, muddy water lowers efficiency, so insert a sleeve pipe that cooperates with the aperture (6) at each hell place, sleeve pipe (6) top end has a directed breach, connect the gutter (2) of leading to sedimentation basin (3), the end in addition of sedimentation basin (3) is connected for clarification pond (4) or with the outer gutter (5) of external river, river, lake, ditch.

The jetting device is fixing vertical with conduit or be the single-nozzle (8) of an angle and the discharge jet (7) of formation in its end by straight catheter.The adjustable in length of conduit, many conduits can connect into long duct (9), and this used water source of jetting device can be the recirculated water in river, river, pond, well and the clarification pond (4).

Earlier discharge jet (7) is inserted in the boring (1) during construction, press water is rushed at a side soil body of the required correction of building by pressure water pump by discharge jet (7), at this moment the breach of sleeve pipe (6) top on it that shove on the mud flows into gutter (2), the sedimentation basin (3) that is connected with it, mud is post precipitation in sedimentation basin (3), completely can excavate if become silted up.And clear water flows into clarification pond (4), recycles or flows in river, river, pond, the ditch by outer gutter (5).

Sectional, layering are from top to bottom or mobile from top to bottom discharge jet (7), make it be fan-shaped direction jet water course, rush at the soil body, constantly drive and influx sleeve pipe (6) mouth on the mud, overflow again to gutter (2), sedimentation basin (3), clarification pond (4), constantly repeat bath, spoil disposal, make the continuous creep of the soil body, rheology, be disturbed, till building is progressively set upright, rectified a deviation.This kind method is continuous firing uninterruptedly, need not pause.Also configurable many water pumps, discharge jet are simultaneously to each drilling construction, to increase construction speed.

Sometimes boring bath back enlarges makes the cover tube failure, can put into slush pump and extract mud out.

The present invention is compared with prior art: only need at building its opposite sidetracking hole that tilts just can rectify a deviation and execute The worker, simple, the easy row of its method. Also can construct in intensive residential block, because not beating vertical shaft, open fixing penetrating Discharge orifice and return port so take up an area lessly, have reduced operating expenses. The operator does not need to construct under the vertical shaft yet, Alleviated again constructor's labour intensity, again safety. And sectional, layering, at arbitrary height and random angle The degree position to soil body jetting, is not subjected to the restriction of jet orifice with discharge jet, i.e. flexible operation, convenience, easy, Laborsaving, province's expense again. Be particularly suitable in muck soil, using.
