Description

A Rotational Displacement and Tilt Correction Method for Building Underpinning Foundation

technical field

The present disclosure relates to the field of building inclination correction, in particular to a method for rotation and displacement of a building underpinning foundation.

Background technique

The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art.

Building tilt rectification refers to the uneven settlement of the foundation of the building due to some reason of the foundation, the foundation or the building itself, and its superstructure deviates from the vertical position and tilts. The measures taken to ensure the safety of the building and restore its normal use function when it affects the safety and normal use of the building.

Building displacement is the process of setting up underpinning chassis and displacement rails under the original building, cutting the upper structure of the building from the original foundation, and setting up a traction or push device on one side of the building to move the building to a new site. The general building displacement technology mostly moves the building along the horizontal direction.

The inventors found that, at present, a circular arc-shaped track is arranged in the inclined direction of the building, and the inclination correction is realized by sliding along the circular-arc-shaped track. However, the rotation path of this method is two-dimensional, and its cross-section is a part of the arc, and the applicable conditions are limited: only the inclination direction of the building is consistent with the main axis arrangement direction of the vertical components (columns or walls) of the building, can this method be used Methods: During the traditional displacement process, the stability between the underpinning beams is not good, and the spacing between adjacent frame columns is easily changed, resulting in the bending damage of the frame columns; Seismic isolation can be achieved only when the direction of the rotation and displacement of the building is the same; however, the inclination direction of the building is related to the distribution of the foundation soil, which is very random, and rarely coincides with the arrangement direction of the main axis of the vertical components of the building. The generation is also random and cannot be exactly the same as the setting direction of the seismic isolation structure of the building. Therefore, for buildings inclined in any direction, and for earthquakes generated in any direction, the current tilt correction methods and seismic isolation structures are difficult to meet. need.

SUMMARY OF THE INVENTION

The purpose disclosed by the present invention is to provide a method for rectifying the inclination of a building underpinning foundation by rotation, displacement, and inclination in view of the defects in the prior art. The beam constructs the underpinning foundation. After truncating the connection between the independent foundation and the frame column, the underpinning foundation drives the rotation and displacement of the building along the displacement track to realize the effective tilt correction of the three-dimensional space trajectory.

A method for rotation, displacement and tilt correction of a building underpinning foundation, comprising the following steps:

Excavation of work pits around buildings to expose all freestanding foundations;

The track foundation is poured above the independent foundation. The side of the track foundation facing the building forms a space curved surface in the shape of the inner surface of the sphere. The space curved surface covers all the independent foundations, and the displaced track is laid along the space curved surface;

The underpinning beams are poured on both sides of the frame columns of the building, and the underpinning beams clamp the frame columns from both sides and are fixedly connected with them;

Pouring between the top surface of the underpinning beam and the displacement track, leaving a construction gap around the frame column to form an underpinning foundation whose bottom adapts to the space curved surface;

The connection between the frame column and the independent foundation is cut off from the construction gap, and the building load is transferred from the frame column and the independent foundation to the underpinning beam, the underpinning foundation, the displacement track, and the track foundation transfer;

Fill construction voids to form a complete bowl-shaped underpinning foundation;

Drive the underpinning foundation to rotate and shift along the displacement track, and stop when the inclination rate of the upper building gradually decreases to meet the specifications;

Deal with the work pit and complete the correction.

Further, the working pit is a ring-shaped working pit, and the diameter is greater than the length of the diagonal line of the building, so that all independent foundations are within the scope of the working pit, and the deepest point of the working pit reaches the maximum settlement and the position of the bottom surface of the independent foundation is the elevation.

Further, the spherical center of the corresponding space surface of the track foundation is located directly above the centroid of the building plane, and the independent foundations are all poured into the track foundation.

Further, the track foundation corresponds to the side with the small settlement of the building, and the track foundation extends to the outer edge of the independent foundation; for the side with a large settlement of the building, the track foundation extends to the outside of the independent foundation and increases the arc length of the rotational displacement. .

Further, underpinning beams are poured on both sides of the longitudinal frame columns or transverse frame columns of the building, and the underpinning beams are connected with the frame columns through pre-implanted steel bars in the frame columns, and clamp the frame columns from both sides.

Further, the underpinning beam and the frame column are arranged vertically, and the beam bottom elevation of the underpinning beam is greater than the elevation of the intersection of the outermost frame column and the rotational displacement track.

Further, the underpinning foundation is cast in sections along the arrangement direction of the underpinning beam, and the underpinning foundation adopts the plate part suitable for the curved surface displacement track as the bottom template to form a bowl-shaped underpinning foundation. Beams connect frame columns.

Further, after the connection between the frame column and the independent foundation is cut off, the track foundation and the displacement track at the position of the frame column are constructed to form a complete rotation and displacement track of the three-dimensional space curved structure, and the construction gap is filled to form a complete bowl-shaped underpinning. Base.

Further, in the process that the underpinning foundation drives the building to move along the displacement track, the position of the highest point gradually decreases while rotating along the circumferential direction, and the position of the lowest point gradually rises while rotating along the circumferential direction, so that the top surface of the underpinning foundation tends to move. On the horizontal, the building slope gradually decreases to meet the demand.

Compared with the prior art, the advantages and positive effects of the present disclosure are:

(1) Lay the displacement track by establishing a track foundation with a space curved surface, and set the underpinning beam for the inclined building to construct the underpinning foundation. After truncating the connection between the independent foundation and the frame column, the underpinning foundation drives the building along the displacement. The rotation and displacement of the track realizes the effective tilt correction of the three-dimensional space trajectory. For the overall tilt that may occur in any direction of the building, the tilt correction is realized by the rotation and displacement of the three-dimensional space curved track, which overcomes the current difficulty in correcting the tilt direction of the two-dimensional path. Inconsistent with the arrangement direction of the main shaft, the inclination rectification is limited, and after the inclination is rectified, a self-recovery structure that can isolate the earthquake force in any direction can be formed;

(2) The method of rotation and displacement is used to correct the tilt, which is simpler, safer and more controllable than the forced landing method. It does not need to estimate the amount of settlement, soil excavation and irrigation in advance, and only needs to use conventional measurement methods to intuitively complete the correction. It can smoothly and stably realize the rotation and tilt correction of the whole building, improve the reliability in the process of tilt correction, and ensure the stability of the overall structure of the frame-type building;

(3) The constructed trajectory surface is a spherical partial structure of a three-dimensional space curved surface, which can be suitable for ground settlement rectification in any direction, as well as isolation effects for earthquakes in any direction, overcoming the two-dimensional path rectification mentioned in the background art. limitation;

(4) Between the underpinning beams corresponding to the frame columns of adjacent columns, the underpinning foundation connection is formed by pouring, which maintains the spacing between adjacent frame columns, increases the strength of the underpinning beams, and overcomes the traditional displacement. During the process, the stability between the underpinning beams is not good, and the spacing between adjacent frame columns is prone to change, resulting in the bending damage of the frame columns, which improves the protection of the overall frame structure of the building.

As described in the background art, in the prior art, a circular arc track is set in the direction of the building's inclination, and the inclination correction is realized by the method of rotation and displacement; however, the rotation path of this method is two-dimensional, and the applicable conditions are limited. ; In view of the above problems, the present disclosure proposes a method for correcting the inclination of a building underpinning by rotation, displacement, and inclination.

Example 1

In a typical implementation of the present disclosure, as shown in FIGS. 1-18 , a method for rectifying the rotation, displacement, and inclination of a building underpinning foundation is proposed.

It is a method that can correct the overall inclination that may occur in any direction of the building, through the rotation and displacement of the three-dimensional space curved track, and is not limited by the settlement direction, and after the inclination is corrected, it can form a self-isolation method for seismic force in any direction. restore structure.

Include the following steps:

A method for rotation, displacement and tilt correction of a building underpinning foundation, comprising the following steps:

Excavate a work pit around the building to expose all independent foundations 4. The work pit is a circular work pit with a diameter greater than the length of the diagonal of the building, so that all independent foundations are within the scope of the work pit, and the deepest part of the work pit reaches settlement. The position of the bottom surface of the largest independent foundation is the elevation;

The track foundation is poured above the independent foundation. The side of the track foundation facing the building forms a space surface in the shape of part of the inner surface of the sphere. The space surface covers all the independent foundations. The center of the space surface corresponding to the track foundation is located directly above the center of the building plane. , the independent foundations are all cast in the track foundation, and the displaced track is laid along the space surface;

The underpinning beams are poured on both sides of the frame columns of the building, and the underpinning beams clamp the frame columns from both sides and are fixedly connected with them;

Pouring between the top surface of the underpinning beam and the displacement track, leaving a construction gap around the frame column to form an underpinning foundation whose bottom adapts to the space curved surface;

The connection between the frame column and the independent foundation is cut off from the construction gap, and the building load is transferred from the frame column and the independent foundation to the underpinning beam, the underpinning foundation, the displacement track, and the track foundation transfer;

Fill construction voids to form a complete bowl-shaped underpinning foundation;

After cutting off the connection between the frame column and the independent foundation, construct the track foundation and displacement track at the position of the frame column to form a complete three-dimensional space curved surface structure of the rotational displacement track, fill the construction gap, and form a complete bowl-shaped underpinning foundation;

Drive the underpinning foundation to rotate and shift along the displacement track. During the process that the underpinning foundation drives the foundation to move along the displacement track, its highest point position gradually decreases while rotating along the ring direction, and the lowest point position gradually rises while rotating along the ring direction. , so that the top surface of the underpinning foundation tends to be level, and the inclination rate of the building gradually decreases, until the inclination rate of the upper building gradually decreases to meet the specifications and stops;

Deal with the work pit and complete the rectification; after the rectification, the top surface of the underpinning foundation will be constructed, and the earthwork of the work pit will be backfilled to restore the function of the building.

Specifically, with reference to the accompanying drawings, the tilt correction method in this embodiment is described in detail:

For the convenience of expression, the origin of the Cartesian coordinate system is set to coincide with the centroid of the building, and the length direction of the building is defined as the longitudinal direction, which is represented by the X-axis direction of the Cartesian coordinate system. ) Coordinate axis 1; define the width direction of the building as the horizontal direction, represented by the Y-axis direction, and the figure is along the horizontal (Y-axis) coordinate axis of the building; define the vertical direction of the building as the Z-axis direction; The inclination direction is any direction, and generally does not coincide with the X and Y axis directions. The figure shows the overall inclination and sinking direction of the building 3.

The rectification method includes the following steps:

1) Excavate a ring-shaped working pit in the foundation soil 6 around the inclined building, and the diameter of the ring of the working pit should be larger than the diagonal length of the building to ensure that all independent foundations 4 are within the scope of the working pit;

The deepest point of the working pit should reach the maximum settlement and the bottom surface of the independent foundation should be the elevation to ensure that all the independent foundations are exposed in the working pit. The frame column 5 above the independent foundation corresponds to the frame beam plate 7 between the frame columns;

The circular edge line of the slope top of the annular working pit is the intersection line between the working pit and the natural ground, that is, the upper edge line 8 of the working pit slope.

2) The rotational displacement track foundation of the three-dimensional partial sphere inner surface space curved structure is poured with concrete above the independent foundation.

It is understandable that since the frame column is not disconnected from the independent foundation, the rotational displacement track foundation here cannot be constructed temporarily, and the sphere center of the track foundation should be directly above the center of the building plane;

The radius of the sphere is usually set to 3 to 4 times the height of the building.

The bottom vertex of the track shall pass through the top surface of the independent foundation at the centroid of the plane. If there is no independent foundation at the centroid, the higher point of the top surface of the adjacent independent foundation shall be taken; the elevation of the track shall be guaranteed to be higher than the top of all independent foundations. noodle;

The range of track setting should extend to the outer edge of the independent foundation on the side with small settlement of the building; on the side with large settlement of the building, in addition to extending to the outer edge of the independent foundation, the arc length of the rotational displacement should be increased. , the distance can be calculated according to the following formula:

L=γR

In the formula, L is the distance of the rotational displacement of the building; γ is the inclination of the building; R is the radius of the trajectory line of the rotational displacement.

3) Lay a rotational displacement track on the surface of the space curved track foundation.

The track can be smooth steel plate or tetrafluoroethylene plate. The curvature of the track is the same as the curvature of the base. The upper surface of the track is painted with grease to reduce the resistance during rotational displacement;

The intersection line of the rotation displacement track corresponding to the top surface of the track base is the boundary line 9 of the rotation displacement track.

4) Pouring reinforced concrete underpinning beams 10 on both sides of the longitudinal frame columns of the building, the underpinning beams are connected to the frame columns through pre-implanted steel bars in the frame columns, and clamp the frame columns from both sides.

It can be understood that the concrete underpinning beams can also be poured from both sides of the horizontal frame columns of the building, and are also fixedly connected with the frame columns through pre-injected steel bars;

It should be pointed out that since the underpinning beams need to cooperate with pouring to form the underpinning foundation, there is no need to arrange the underpinning beams vertically and horizontally. Reduced construction steps for underpinning beams.

The underpinning beam is perpendicular to the frame column. Since the frame column is inclined before it is rectified, the angle between the underpinning beam and the horizontal plane and the inclination angle of the frame column are the same.

In order to ensure the connection between the underpinning beam and the longitudinal (or transverse) frame column, the beam bottom elevation of the underpinning beam should be greater than the elevation of the intersection of the outermost frame column and the rotational displacement track.

5) The reinforced concrete bowl-shaped underpinning foundation 11 is cast in sections along the longitudinal (or transverse) direction of the building.

According to the arrangement in step 4), if the underpinning beams are arranged on both sides of the longitudinal frame columns of the building, the underpinning foundation shall be cast in sections along the longitudinal direction. Underpinning the foundation to facilitate the pouring operation.

The foundation should adopt the steel plate or tetrafluoroethylene plate with the same curvature as the curved track as the bottom formwork, and the top surface of the foundation and the underpinning beam have the same inclination angle.

When the bowl-shaped underpinning foundation is poured to the vicinity of the frame column, the pouring is stopped, and the vertical construction gap is left. Each section of the bowl-shaped foundation is connected to the frame column by means of underpinning beams.

It can be understood that, between the underpinning beams corresponding to the frame columns of adjacent columns, the underpinning foundation connection is formed by pouring, which maintains the spacing between adjacent frame columns, increases the strength of the underpinning beams, and overcomes the traditional During the displacement process, the stability between the underpinning beams is not good, and the spacing between adjacent frame columns is prone to change, resulting in the bending damage of the frame columns, which improves the protection of the overall frame structure of the building.

6) In the gap of each bowl-shaped underpinning foundation, cut off the connection between the frame column and the independent foundation.

At this time, the load of the upper building is transferred from the frame column to the underpinning beam, the bowl-shaped underpinning foundation, the displacement track, the rotational displacement track foundation, and finally transferred to the foundation soil.

7) The rotational displacement foundation and track of the construction frame column position form the rotational displacement track of the complete three-dimensional space curved surface structure.

At the same time, the gap between each bowl-shaped underpinning foundation is poured to form a complete bowl-shaped underpinning foundation.

8) A traction device is installed on the top of the slope in the direction of maximum settlement, and the bowl-shaped underpinning foundation and the buildings supported by it are pulled and rotated along the space curve track, and the inclination rate of the upper frame structure is gradually reduced. When the inclination rate meets the specification requirements, stop the rotation displacement.

Specifically, in this embodiment, when the underpinning foundation drives the foundation to move along the displacement track, the position of the highest point gradually decreases while rotating along the circumferential direction, and the position of the lowest point gradually rises while rotating along the circumferential direction, so that the underpinning position gradually rises. The top surface of the replacement foundation tends to be level, and the building slope is gradually reduced to meet the demand.

9) Remove the displacement traction device.

Construct the floor on the top surface of the bowl-shaped underpinning foundation, backfill the earthwork of the working pit, and restore the function of the building.

For the realization of multi-directional seismic isolation, under the action of horizontal seismic force, the building will generate corresponding rotational moment, and will slide along the space curved track;

After leaving the equilibrium position with a certain inclination angle, the component force of the building weight along the tangential direction of the curved surface will increase; the elastic force opposite to the movement direction will be generated;

In addition, the bottom surface of the underpinning foundation and the contact surface of the displacement track itself have friction; the moment generated by the two forces will block the building from further rotation, and even return to the original equilibrium position. The energy dissipation effect is produced in the reciprocating motion, and the earthquake damage of the building is prevented.

The energy dissipation effect is produced in the reciprocating motion, and the earthquake damage of the building is prevented.

The displacement track is laid by establishing a track foundation with a space curved surface, and the underpinning beam is set for the inclined building to construct the underpinning foundation. After the connection between the independent foundation and the frame column is cut off, the rotation of the building along the displacement track is driven by the underpinning foundation. Shift to achieve effective tilt correction of the three-dimensional trajectory space trajectory;

For the overall inclination that may occur in any direction of the building, the inclination correction is realized by the rotation and displacement of the three-dimensional space curved track, which overcomes the limitation that the current two-dimensional path inclination correction is difficult to correct the inclination direction and the main axis arrangement direction. Form a self-healing structure that can isolate earthquakes in any direction.

The above descriptions are only preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure should be included within the protection scope of the present disclosure.
