Example 1
In an exemplary embodiment of the present disclosure, as shown in fig. 1 to 17, a spatial curved surface rotation displacement rectification method for a brick-concrete structure building is provided.
The method for realizing the rectification by the rotation and the displacement of the three-dimensional space curved surface orbit can be used for the integral inclination possibly generated in any direction of the building, is not limited by the settlement direction, and can form a self-recovery structure for realizing the shock insulation of the earthquake acting force in any direction after the rectification.
The method comprises the following steps:
a method for correcting inclination of a brick-concrete structure building by rotating, shifting and correcting a spatial curved surface comprises the following steps:
excavating an annular working pit around the building, and forming a space curved surface structure with the appearance corresponding to the inner surface of the spherical part on a side slope of the working pit;
excavating a working pit, and completely exposing the strip foundation below the wall body of the brick-concrete structure;
pouring underpinning beams on the top of the strip foundation 5 and two sides of the wall 4, clamping the wall from two sides and fixedly connecting the wall through connecting keys, wherein the underpinning beams are arranged in parallel along the direction of the wall;
laying a rotary displacement track on the side slope of the working pit corresponding to the space curved surface structure of the working pit, and arranging an annular curved beam as a support of the underpinning beam at the position where the rotary displacement track and the underpinning beam form a plane intersection curve;
excavating earthwork below the strip-shaped foundation, so that the load of the brick-concrete structure building is directly transferred to the foundation from the strip-shaped foundation to be transferred to the foundation below the side slope through the underpinning beam, the annular curved beam and the rotary displacement track;
arranging a traction device at the top of the side slope in the maximum sedimentation direction, driving the annular curved beam to drive the building to rotate and displace along the space curve rotation displacement track, and stopping after the inclination rate of the upper brick-concrete structure building is gradually reduced to meet the specification;
and processing the working pit to finish rectification.
Furthermore, the annular curved beam is positioned between the end part of the underpinning beam and the rotary displacement track, and the height of the annular curved beam is greater than that of the underpinning beam; the curvature of the contact surface of the annular curved beam and the space curved surface rotation displacement track is the same as that of the rotation displacement track, and the included angle between the annular curved beam and the horizontal plane is the same as the inclination angle of the wall body.
Specifically, the inclination correction method in this embodiment is described in detail with reference to the accompanying drawings:
for the convenience of expression, setting the origin of a Cartesian coordinate system to coincide with the centroid of the building, defining the length direction of the building as the longitudinal direction, and expressing the length direction by the X-axis direction of the Cartesian coordinate system, wherein the coordinate axis is 1 along the longitudinal direction (X-axis) of the building; defining the width direction of the building as the transverse direction, and representing the width direction by the Y-axis direction, wherein the width direction is along the transverse (Y-axis) coordinate axis 2 of the building; defining the vertical direction of a building as the Z-axis direction; the overall inclination direction of the building is arbitrary, and generally does not coincide with the X, Y axis direction, and is shown as the overall inclination sinking direction 3 of the building.
The rectification method comprises the following steps:
1) digging an annular working pit in foundation soil 6 around a building with an inclination, wherein the shape of a side slope of the working pit is a three-dimensional space curved surface structure of the inner surface of a partial sphere;
it should be noted that the sphere center of the sphere should be directly above the building plane centroid; in order to prevent the radian from greatly increasing traction force during rotation and displacement and simultaneously consider the anti-overturning capacity of the building in a use state, the radius of the sphere is usually set to be the vertical distance from the vertical gravity center of the building to the bottom surface of the foundation, so that the acting force of the sphere center cannot generate the overturning moment of the building rotating along the track;
the round side line of the slope bottom of the side slope is the intersection line of the sphere and the horizontal plane with the bottom surface position of the strip-shaped foundation with the maximum sedimentation as the standard height, namely the lower side line 8 of the side slope, and the diameter of the circle is larger than the length of the diagonal line of the building so as to ensure that all the strip-shaped foundations are in the range of the working pit; the circular edge line of the slope top is the intersection line of the sphere and the natural ground, namely the edge line 7 of the slope.
2) Excavating a working pit, and completely exposing the strip foundation 5 below the brick-concrete column;
the maximum foundation settlement position can be excavated to the elevation of the slope bottom edge line of the working pit; and excavating the foundation at other positions to the bottom surface of the foundation, and excavating a slope between the foundation and the slope bottom edge line of the working pit.
3) Laying a rotary displacement track 11 on a side slope of a space curved surface track working pit;
the rail can be a smooth steel plate or a tetrafluoroethylene plate. The curvature of the track is the same as that of the side slope; the upper surface of the rail is coated with grease to reduce resistance to rotational displacement.
4) Pouring reinforced concrete underpinning beams on two sides of the wall 4 at the top of the strip foundation, connecting the underpinning beams with the wall through reinforced concrete connecting keys 12 arranged at regular intervals, and clamping the wall from two sides;
the underpinning beam is parallel and vertical to the wall body, and because the brick-concrete structure wall body is inclined before rectification, the included angle between the underpinning beam and the horizontal plane is the same as the inclination angle of the wall body.
5) Arranging a reinforced concrete annular curved beam 9 at the position of a plane intersection curve formed by the space curved surface track and the longitudinal and transverse underpinning beams, wherein the height of the annular curved beam is greater than that of the underpinning beam so as to be used as a support of the underpinning beam;
the curvature of the contact surface of the annular curved beam and the space curved surface track is the same as that of the curved surface track; when the annular curved beam is poured with concrete, a steel plate or a tetrafluoroethylene plate with the same curvature as the curved surface track is preferably adopted as a bottom template; the included angle between the plane of the annular curved beam and the horizontal plane is the same as the inclined angle of the wall body.
If the included angle between the plane of the annular curved beam and the horizontal plane is too large, the bottom surface of the annular curved beam at the side with small building settlement cannot be in full contact with the track, and earthwork should be filled outside the working pit when the curved track is constructed in the construction space, so that the length of the track is properly prolonged.
6) Excavating earthwork below the strip-shaped foundation until the bottom surface of the strip-shaped foundation with the maximum sedimentation is a standard height horizontal plane; at the moment, the load of the brick-concrete structure building is directly transferred to the foundation from the strip foundation to be transferred to the foundation below the side slope through the underpinning beam, the annular curved beam and the rotary displacement track.
7) A traction device is arranged at the top of the side slope in the maximum sedimentation direction, the annular curved beam and a building supported by the annular curved beam are dragged, rotated and displaced along a space curve track, and the inclination rate of the upper brick-concrete structure is gradually reduced;
in the process of movement of the annular curved beam, the highest point of the annular curved beam gradually descends while rotating in the annular direction, and the lowest point of the annular curved beam gradually ascends while rotating in the annular direction, so that the radial plane of the annular curved beam tends to be horizontal, and the inclination rate of a building is gradually reduced;
and when the inclination rate meets the specification requirement, stopping the rotation and the displacement.
8) And (5) removing the shifting traction device.
9) A laminated rubber support (generally formed by bonding a plurality of layers of waste rubber tire cutting sheets) is filled in a gap between the bottom of the annular curved beam and the bottom surface of the working pit to form a laminated rubber limiting block 13;
the support assists the side slope foundation to bear the load of the upper building in a normal use state; under the action of earthquake, the building can play a role in limiting and dissipating energy when sliding.
10) In non-earthquake-proof areas, concrete can be filled between the original strip foundation and foundation soil, a force transmission path of upper load is increased, and the upper structure is supported together with the ring beam and the side slope.
11) And (4) pouring concrete floor surfaces on the annular curved beam and the underpinned beam top to restore the use function of the building.
For the realization of multi-direction shock insulation, under the action of horizontal seismic force, a building can generate corresponding rotating moment and can slide along a space curved surface track;
when the building leaves the balance position for a certain inclination angle, the component force of the weight of the building along the tangent direction of the curved surface can be increased; meanwhile, the rubber interlayer support on the other side of the rotary motion direction is continuously compressed to generate elastic force opposite to the motion direction;
in addition, the contact surface between the annular curved beam and the track has friction force; the moment generated by the three forces can retard the building to further rotate and even restore the original balance position.
The energy consumption effect is generated in the reciprocating motion, and the shock damage of the building is prevented.
The constructed track surface is a spherical part structure of a three-dimensional space curved surface, can be suitable for foundation settlement rectification in any direction and generate a shock insulation effect on earthquakes in any direction, overcomes the limitation of two-dimensional path rectification in the background technology, and takes an annular curved beam as a rotary moving device without arranging a rotary moving device along the full length of a track, so that the body type is light and handy, and materials are saved.
The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure, and various modifications and changes may be made to the present disclosure by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present disclosure should be included in the protection scope of the present disclosure.
