Abstract
The method for inclination correction and reinforcement of multi-story building with pile foundation features that according to designed settlement, cross section at the pile necks under cap is sequentially decreased, under action of load, said pile necks are gradually damaged until correction is finished, and additional small piles are added and connected to original foundation by casting. Its advantages include easy construction and low cost.
Description
The present invention relates to a kind of building inclination correcting and then reinforcing method, particularly the pile foundation house of many high levels is correcting and then reinforcing inclined.
When the house run-off the straight,, can adopt substrate soil digging method for correcting error for the house of direct foundation.But for adopting pile foundation and weak soil bed thickness, it is not enough and the inclined building that causes then is difficult to use above method to carry out rectification that the stake end does not reach foundation bearing capacity such as hardpan.
The object of the present invention is to provide a kind of straightening reinforcing method that is applicable to the pile foundation house of multilayer.
Technical scheme of the present invention is: the first step, the pile neck position under the cushion cap is pressed designed amount of precipitation preface minimizing dowel section area successively, and under load effect, a stake neck is damaged by pressure distortion gradually, finishes until correction.Second step underpined by design that loading is other on former basis to add small pile, watered to smash cushion cap and former basis links together.
The invention has the advantages that: construction is simple, and is easy to operate, and the duration is short, and the above resident family of construction period second floor need not move, and expense is low.
Further specify the present invention and embodiment below by accompanying drawing.
Accompanying drawing 1, working pit and cut a schematic diagram.
Accompanying drawing 2, underpin reinforcement schematic diagram.
Accompanying drawing 3, reinforcing layout schematic diagram.
The concrete construction sequence of implementing is as follows:
1, calculate the designed amount of precipitation of every required stake of cutting and the loading that need underpin, and new piling of design and cloth hole.
2, carry out the construction of new piling 4, new piling 4 can be slim hole stake, root pile or static pressure preformed pile etc.
3, control out working pit 6 and clear up 2 ends of former cushion cap at the place, basis.
4, at stake neck 12 places, to reserve and cut stake position 13, addition of constraints hoop 3 is cut stake and is no more than 5 centimeters at every turn.
5, cut stake and reduce a dowel section area cutting 13 places, stake position.
6, billet is prepared in observation, is put in and is out of shape pile neck position faster, prevents that too fast distortion from causing superstructure to produce the crack.
7, circulation 4,5,6 step several times are corrected up to the house.
8, press pile neck position to add stirrup, water with cushion cap and build up expansion pile crown 11.
9, water and smash new cushion cap 5 and will newly add stake and 4 and former basic 2 link together, connected mode can connect with bag pillar cushion cap, also available bottom-supported type cushion cap connection.
Claims (3)
1, a kind of inclined building straightening reinforcing method, it is characterized in that, earlier the pile neck position under the cushion cap is pressed designed amount of precipitation preface minimizing dowel section area successively, under load effect, the stake neck is damaged by pressure distortion gradually, finishes until correction, underpins loading by design again, otherly on former basis add small pile, water and smash cushion cap and former basis links together.
2, inclined building straightening reinforcing method according to claim 1 is characterized in that: pile neck position is cut stake and is needed the addition of constraints hoop, and cuts stake at every turn and sink to being no more than 5 millimeters.
3, inclined building straightening reinforcing method according to claim 1 is characterized in that: underpining small pile can be slim hole stake, root pile or static pressure preformed pile.
