Technical Field

[0001] This application relates to the field of structural reinforcement and inclination correction of ancient cultural relics pagoda structures, and in particular to a reinforcement and inclination correction structure for ancient cultural relics brick and stone pagoda structures. Background Art

[0002] At present, for traditional brick and stone structures of buildings (structures), in ancient times, the productivity was relatively low, and the material acquisition and processing technologies were limited. Bricks and stones are widely available and relatively easy to process materials, so they have become the main choice for construction. In ancient China, the long-term agricultural civilization provided a stable source of building materials for brick and stone structures of buildings (structures).

[0003] For ancient brick and stone pagodas, the tower body is built on a shallow foundation of natural ground. Under natural environments such as rain erosion, ground moisture, high humidity, and plant growth, due to lack of maintenance and repair over the years, the bricks and stones of the tower body are weathered and cracked, the foundation undergoes uneven settlement, and the mechanical properties of the brick and stone materials decline, which may lead to structural instability, risks of deformation, cracks, and even collapse, shortening the service life of the building (structure).

[0004] Therefore, for ancient cultural relics brick and stone pagoda structures with serious inclination and deformation and poor overall stability, reinforcement and inclination correction are carried out to ensure the structural safety of the ancient cultural relics pagoda structures.

[0035] The following will further elaborate on the present application in conjunction with the attached Figure 1-8 drawings.

[0036] An embodiment of the present application discloses a reinforcement and inclination correction structure for a cultural relic brick and stone ancient pagoda structure.

[0037] Example 1

[0038] Refer to Figure 1 、 2 、5, a reinforcement and inclination correction structure for a cultural relic brick and stone ancient pagoda structure, including a basalt tower base 1 and an inclined tower body 2 above the basalt tower base 1. Pressure grouting (with a depth of about 1 m) construction is carried out on the lower side of the basalt tower base 1 to solidify the bearing layer under the basalt tower base 1. Then, the foundation of the ancient pagoda is excavated in sections. For the local and through cracks on the inner and outer sides of the tower body 2, C50 high-strength reinforcement grouting material 9 is used for grouting repair on the inner side, and high-strength glue injection is considered for repair on the lower part of the outer side considering grouting weathering and material characteristics. The upper part of the basalt tower base 1 is cast with a raft foundation 4 by concrete. And before pouring the concrete of the raft foundation 4, horizontal distribution steel bars 10 and vertical distribution steel bars 10 are tied inside it, distributed in a double layer of 200 cm * 200 cm, with local reinforcement treatment (such as Figure 2 、 5 shown).

[0039] Through the above settings, pressure grouting (with a depth of about 1 m) construction is carried out on the lower side of the basalt tower base 1 to solidify the bearing layer under the basalt tower base 1. Then, the foundation of the ancient pagoda is excavated in sections. And the upper part of the basalt tower base 1 is cast with a raft foundation 4 by concrete. These are all preparations for foundation reinforcement and construction jacking of the lower chassis.

[0040] Refer to Figure 1 、 4 、6, and a number of cushion blocks 8 are placed on the upper part of the raft foundation 4. And 200t follower jacks 6 are placed on the upper ends of a part of the number of cushion blocks 8, and 150t hydraulic jacks 7 are placed on the upper ends of another part of the number of cushion blocks 8. And a number of 200t follower jacks 6 and 150t hydraulic jacks 7 are all located under the upper tray 5. And a number of 200t follower jacks 6 and 150t hydraulic jacks 7 provide support and upward thrust for the upper tray 5. And a number of wall-piercing I-beams 15 are arranged in the inner cavity of the upper tray 5. And a number of wall-piercing I-beams 15 are arranged in an array and fixedly penetrate through the entire upper tray 5 from the side of the upper tray 5 (such as Figure 4 shown).

[0041] With the above settings, when the distances between the 200t follow-up jack 6 and the 150t hydraulic jack 7 and the upper tray 5 are large, the spacer blocks 8 can be placed under the 200t follow-up jack 6 and the 150t hydraulic jack 7 to reduce the distances between the 200t follow-up jack 6 and the 150t hydraulic jack 7 and the upper tray 5, and the wall-piercing I-beam 15 can provide better support for the upper tray 5.

[0042] It should be noted that the numbers of the 200t follow-up jack 6 and the 150t hydraulic jack 7 need to be set according to the self-weight of the corresponding ancient pagoda.

[0043] Refer to Figure 2 、 7 、8, and above the upper tray 5 is the tower body 2. The outer wall surface of the tower body 2 is fixedly connected to one side surface of the circumferential steel plate 11, and one side of the circumferential steel plate 11 is fixedly welded to a number of vertically arranged vertical steel plates 3 in an array. The inner surface of the tower body 2 is fixedly connected to one side surface of a number of vertically arranged vertical steel columns 13 in an array, and the surfaces of the circumferential steel ring beams 12 symmetrically arranged up and down are fixedly connected between the a number of vertical steel columns 13. The vertical steel plates 3 and the vertical steel columns 13 not only correspond in position, but also have the same number. The circumferential steel ring beams 12 and the circumferential steel plates 11 not only correspond in position, but also have corresponding numbers. One end of a number of vertical steel columns 13 is fixedly penetrated by a tie member 14, and the other end of the tie member 14 also fixedly penetrates a number of vertical steel plates 3. The vertical steel columns 13 and the vertical steel plates 3 are fixedly connected by the tie member 14 (as Figure 8 shown).

[0044] With the above settings, the outside of the tower body is strengthened by using vertical steel plates 3 and circumferential steel plates 11. The plaster layer about 2 cm on the outside of the tower body is fully utilized at the steel plate layout. Before laying the steel plates, the plaster layer at this place is broken. After the steel plates are laid and the rust-proof and fire-proof finishes are completed, the original plastering materials are used for the external wall plastering.

[0045] The circumferential steel plates 11 are arranged corresponding to the inner circumferential steel ring beams 12. The vertical steel plates 3 are arranged separately for each layer and are arranged corresponding to the inner vertical steel columns 13. The upper and lower ends are welded to the circumferential steel plates 11. A number of inner vertical steel columns 13 and a number of outer vertical steel plates 3 are connected by tie members 14 (inserted into the stone joints as much as possible) to form an integral internal and external reinforcement.

[0046] It should be noted that the tower body 2, the basalt tower foundation 1, the 200t follow-up jack 6, the 150t hydraulic jack 7, and the wall-piercing I-beam 15 are all prior arts and will not be elaborated here.

[0047] The implementation principle of the reinforcement and inclination correction structure for the cultural relics brick and stone ancient tower structure in the embodiment of the present application is as follows: First step, the whole tower body 2 is reinforced by combining permanent and temporary reinforcement methods. A construction scaffold is erected on the existing foundation (if the foundation bearing capacity is insufficient, local grouting treatment is required). The reinforcement of the tower body 2 is implemented in layers, and the reinforcement should be carried out in the order from bottom to top and from outside to inside.

[0048] Then, for the local and through cracks on the inner and outer sides of the tower body 2, the inner side is repaired by grouting with C50 high-strength reinforcement grouting material 9, and the outer side is repaired by using high-strength glue injection considering the factors of grouting weathering and material properties. Secondly, the inner side of the tower body 2 is reinforced by using vertical steel columns 13 and circumferential steel ring beams 12. Eight square steels are symmetrically arranged as vertical steel columns 13 inside the basalt tower foundation 1, and two circumferential steel ring beams 12 are symmetrically arranged above and below the waist strip of each layer.

[0049] The outer side of the tower body 2 is reinforced by using a whole vertical steel plate 3 and a circumferential steel plate 11. The plaster layer about 2 cm thick on the outer side of the tower body 2 is fully utilized at the steel plate arrangement position. Before laying the steel plate, the plaster layer at this place is broken, and after the steel plate laying and anti-rust and fire-proof finishing are completed, the original plastering material is used for the external wall plastering. The circumferential steel plate 11 is arranged corresponding to the inner circumferential steel ring beam 12, the vertical steel plate 3 is arranged separately for each layer and is arranged corresponding to the inner vertical steel column 13, and the upper and lower ends are welded to the circumferential steel plate 11. The eight inner vertical steel columns 13 and the eight outer vertical steel plates 3 are connected by tie pieces 14 (inserted as much as possible at the stone joints), so that the internal and external reinforcements form an integral whole.

[0050] Second step, the foundation is reinforced and the lower chassis is jacked up during construction. Since the basalt tower foundation 1 adopts a natural foundation, pressure grouting (with a depth of about 1 m) is carried out under the original foundation of the ancient tower to solidify the bearing stratum under the building foundation, and then the basalt tower foundation 1 of the ancient tower is excavated in sections, and a raft foundation 4 (also used as the jacking lower chassis) is poured with steel bars 10 and concrete.

[0051] The foundation replacement construction is preferably arranged during the dry season. If the construction is carried out during the rainy season, open drainage must be carried out by combining an outer drainage ditch and a sump well.

[0052] Third step, the upper tray 5 structure is constructed. The upper tray 5 structure is constructed in sections at 30 cm above the top elevation of the raft foundation 4. The upper tray 5 can be used as a ring beam of the basalt tower foundation 1 to increase the stability of the tower body 2 without affecting the appearance of the ancient tower. If the upper tray 5 is above ±0.000, it will be statically cut by a wire saw after the inclination correction is completed, and then the outer facade at the position of the upper tray 5 is restored to its original state.

[0053] The upper pallet 5 structure is composed of lifting wall beams, clamping wall beams, connecting beams, etc. The bottom surfaces of the lifting wall beams and clamping wall beams are flush with the top surface of the foundation footing. The joint surface between the clamping wall beams and the brick wall is roughened, and holes are drilled in the wall at the corresponding lifting wall position. After the lifting wall beams and clamping wall beam steel bars 10 are tied and the formwork is supported, concrete is poured. The formwork uses wooden formwork, 5cm×10cm square wood is used as ribs, expansion bolts are driven into the wall, and the formwork is fixed by welding tie rods. Commercial concrete is used, and outdoor concrete is pumped and poured, while indoor concrete is manually transported and poured.

[0054] The lifting wall beam is a tie beam installed at the bottom of the original wall. It can increase the integrity of the connection between the upper sliding beam and prevent the original wall from sinking and cracking after the foundation is cut due to insufficient friction shear force. After calculation, the lifting wall beam is planned to use through-wall I-beam 15 (I 10). Before tying the clamping wall beam, the holes in the original foundation wall are pre-dug, and the through-wall I-beam 15 is placed first. 20cm of the wall is reserved at both ends of the through-wall I-beam 15. High-strength grouting material 9 is used to grout and compact the through-wall I-beam 15 and the original cavity. The lifting wall beam should be completed one by one before the next one can be constructed. The construction spacing is about 0.3m, avoiding door railings and through-wall nodes with clamping wall beams, as well as loose brick wall positions.

[0055] The fourth step is to install the lifting jack between the upper tray 5 and the raft foundation 4, then calculate the deadweight of the ancient tower, and equip it with a 150t hydraulic jack 7 and a 200t follower jack 6 corresponding to the deadweight of the ancient tower. After the structural construction of the upper tray 5 is completed, install the corresponding jacks to the corresponding positions and perform debugging before jacking.

[0056] Step 5: Cut the stones and complete the underpinning. After the corresponding 150t hydraulic jack 7 and 200t follower jack 6 provide the lifting force to the deadweight load of the tower body 2, the pressure is maintained, and the basalt tower base 1 connecting stones between the upper tray 5 and the raft foundation 4 are cut, and the load of the upper structure of the tower body 2 is transferred from the jack to the raft foundation 4.

[0057] The sixth step is to adjust the overall inclination of the tower body 2 according to the designed inclination correction value.

[0058] Step 7: Connect in place. It is planned to use micro-expanded fine stone concrete to fill the gap between the original basalt tower base 1 and the tower body 2. After the strength reaches the design standard, the jacking and tilt correction equipment composed of 150t hydraulic jack 7 and 200t follow-up jack 6 and temporary reinforcement facilities will be removed to restore the original appearance of the site and complete all the overall deviation correction processes of the tower body 2.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
