Embodiment Construction

[0030]Starting from the principle of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0031]The mechanics principle of the pier toppling of the present invention is: after cutting and separating the part within a certain height of the upper part of the pier from the bottom part, the upper part of the cutting line 6 is tilted by the unilateral jacking device to tilt until its center of gravity plumb line exceeds the edge of the bottom part reserved Then fell on its own. The steel rod in it acts as the shaft 1 to prevent local concrete from crushing and the whole upper part from skewing uncontrollably.

[0032]Such asfigure 1 As shown in the two completed bridge piers, the right pier has quality defects and needs to be removed. The removal method includes the following steps:

[0033]1) Determine the location of the pier cutting line 6 based on the distance between the two piers and the specific height of the pier. At...

Abstract

The invention relates to an integral pier overturning method. The method includes the steps that (1), the height of a pier cutting line is determined; (2), a rotary shaft is installed on one side of apier, and the installation height of the rotary shaft is the same as that of the cutting line; (3), a hole needed for an operation space is formed in the other side of the pier in a slotted manner, ajacking device is installed in the hole, and height of the top of the hole is equal to that of the cutting position; and (4), the pier is annularly cut, the structure on the upper portion of the cutting line inclines through the jacking device until the gravity center plumb line of the structure exceeds the edge of a bottom remaining part, and the pier automatically falls down. By the adoption ofthe integral pier overturning method, the technical problems that an existing pier detaching method is large in cost and long in construction period are solved.

Description

Technical field[0001]The invention relates to a method for integrally dismantling high bridge piers, in particular to a method for integrally tearing down bridge piers.Background technique[0002]At present, China's infrastructure construction is vigorously advancing, and the bridge construction sites are wide and numerous. During the construction of some bridge piers, there will be problems such as form expansion, insufficient concrete strength or deviation, and the piers are often high in height, larger in cross-sectional area, and more concrete.[0003]At present, manual picking method and ring-by-ring cutting method are used to demolish unqualified bridge piers. The main problems of these two methods are long construction period and high cost.[0004]With a cross-sectional area of ​​about 16m2, Take a pier with a height of 15m as an example to illustrate the two methods.[0005]Manual picking: If manual picking is used, considering the working surface on the top of the pier, at most two...
