Description

Technical Field

[0001] This invention relates to the field of cultural relic protection technology during building construction, specifically to a method for protecting cultural relics in outdoor construction areas. Background Technology

[0002] When conducting construction projects outdoors, construction teams often encounter numerous cultural relics, especially those that are difficult to move. Since cultural relics are an important part of human cultural heritage, their protection is a crucial task. When construction teams perform excavation work such as foundation pit excavation and slope dredging near cultural relics, it often causes disturbance to the surrounding soil, even leading to subsidence or collapse. This can result in delays in construction progress, damage to cultural relics, and significant safety hazards. Therefore, when carrying out construction in outdoor areas surrounded by cultural relics, cultural protection is essential. Currently, there are no effective means to protect cultural relics in construction areas in real time or by relocating them for timely handling. Summary of the Invention

[0003] This invention aims to provide a method for protecting cultural relics in outdoor construction areas that can promptly detect whether cultural relics have been excessively displaced, solving the problem that existing construction methods cannot detect the displacement of cultural relics in real time in order to reinforce them and prevent damage.

[0004] The above technical problems are solved by the following technical solution: A method for protecting cultural relics in outdoor construction areas, comprising: Step 1, a cultural relic protection structure: the cultural relic protection structure includes a protective fence fitted over the cultural relic and a buffer material filled between the protective fence and the cultural relic; Step 2, an installation and detection mechanism: the detection mechanism includes several foundation piles fixed to the ground on the side of the protective fence away from the outdoor construction area, several cables connecting the foundation piles to the protective fence, and a display structure installed on the cables. The display mechanism is used to provide a prompt when the offset distance of the protective fence towards the construction area reaches a set value or more. The process involves four steps: First, displaying the offset force generated by the protective fence. Second, construction is carried out in the outdoor construction area. During construction, when the display structure indicates that the offset distance of the protective fence towards the construction area has reached or exceeded the set value, construction is stopped. The soil around and under the cultural relic is reinforced until the offset distance of the protective fence towards the construction area is less than the set value, and then construction continues. Third, the cultural relic protection mechanism is dismantled. The soil around and under the cultural relic is reinforced to release the offset force generated by the protective fence as indicated by the display mechanism to meet the requirements. The protective fence is then dismantled and the buffer material is removed. This method effectively protects the cultural relic during construction.

[0005] Preferably, before constructing the cultural relic protection structure, the foundation around the cultural relic is leveled and compacted, a concrete ring beam is poured around the cultural relic, and bolts are pre-embedded in the concrete ring beam. The protective enclosure includes protective rings distributed vertically, each protective ring comprising arc-shaped segments connected end-to-end along the circumference of the protective ring. The lowest protective ring is detachably connected to the concrete ring beam via the pre-embedded bolts and base nuts. Adjacent arc-shaped segments are detachably connected together via arc-shaped segment connecting bolts and arc-shaped segment connecting nuts, and adjacent protective rings are detachably connected together via protective ring connecting bolts and protective ring connecting nuts. The cultural relic protection structure is easy to install and dismantle and can be reused.

[0006] Preferably, the cable includes a first section and a second section. The display mechanism includes an insulating sleeve, a power supply, an indicator light connected to one end of the power supply, a fixed conductive contact connected to the other end of the indicator light, a conductive rod inserted inside the insulating sleeve, a tension gauge located inside the insulating sleeve, and a conductive ring sleeved on the conductive rod. The conductive ring is connected to the other end of the power supply. The conductive ring, indicator light, power supply, and fixed conductive contact are all fixed to the insulating sleeve. The tension gauge connects the insulating sleeve and the conductive rod together. One end of the first section is connected to the protective fence, and the other end is connected to the insulating sleeve. The first and second sections are connected together. One end of the second section is connected to the foundation pile, and the other end is connected to the conductive slide rod. When the first and second sections separate, the conductive slide rod extends out of the insulating sleeve. A tension gauge is used to measure the force required to separate the first and second sections. The conductive slide rod is provided with conductive contacts. When the conductive slide rod exits the insulating sleeve, the conductive contacts move towards the fixed conductive contact. When the offset distance of the protective fence towards the construction area reaches the set value, the conductive contacts of the conductive slide rod abut against the fixed conductive contact. The insulating sleeve is provided with a window for observing the reading of the tension gauge. A specific technical solution for the display mechanism is provided.

[0007] Preferably, the lower end of the foundation pile is provided with a pointed tip.

[0008] Preferably, the upper end of the pile is provided with a pull hole. The reference is pulled out by pulling up the reference through the pull hole. This makes it convenient to pull out the pile.

[0009] Preferably, the foundation pile is equipped with several pull-out catches that are located within the ground during use. This improves the reliability of the reference pile when it is fixed to the ground.

[0010] Preferably, the pull-out arrestor is a diagonal bar structure with the end furthest from the pile inclined downwards. This provides a better pull-out arresting effect.

[0011] As another preferred embodiment, the pull-out catch is an inclined bar structure with one end facing upwards away from the pile.

[0012] Preferably, the pile has a blind hole penetrating the upper end face of the pile. The middle part of the pull-out catch is hinged to the pile via a rotating shaft. A partition is provided inside the blind hole, and a vertical screw is threaded onto the partition. The partition divides the blind hole into an upper cavity and a lower cavity. The rotating shaft is located in the lower cavity. The side wall of the lower cavity has a clearance hole for the pull-out catch to enter and exit. The vertical screw has a lifting block located below the inner end of the pull-out catch and a pressing block located above the inner end of the pull-out catch. The lower cavity has a pull-out catch opening limit structure to keep the pull-out catch in the open state. When the vertical screw moves downwards, the pressing block presses down on the inner end of the pull-out catch; when the lifting block descends to its limit position, the pull-out catch is in a position where the torque generated by the pull-out catch's gravity drives the upper end of the pull-out catch to rotate towards the lower cavity around the pivot axis; when the lifting block descends to its limit position and the lower end of the pull-out catch abuts against the lifting block, the torque generated by the pull-out catch's gravity drives the upper end of the pull-out catch to rotate towards the lower cavity around the pivot axis, and the torque generated when the lifting block rises drives the upper end of the pull-out catch to rotate towards the outside of the lower cavity around the pivot axis. This technical solution allows the pull-out catch to open and close, saving effort both when the reference nail is driven into the ground and when the pile needs to be pulled out. During the opening and closing process, the structure driving the pull-out catch to open and close is not subjected to the driving force of the pull-out catch, thus it is not easily damaged and can withstand the lifespan of the pile cycle.

[0013] Preferably, the anti-pull grip opening limiting structure includes the lower end wall of the clearance hole and a limiting block located in the lower cavity, with the limiting block and the lower end wall of the clearance hole located on both sides of the rotating shaft; when the anti-pull grip is opened to its limit position, the lower side of the anti-pull grip abuts against the lower end wall of the clearance hole, and the upper side abuts against the lower side of the limiting block. This structure can both limit the movement and prevent the anti-pull grip from breaking.

[0014] The beneficial effects of this invention are: it can prevent damage to cultural relics during construction, can promptly detect whether cultural relics have been displaced excessively and require reinforcement, and can detect the force generated when cultural relics are displaced, thus preventing cultural relics from losing support and being excessively displaced and damaged when the protective mechanism is removed.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Example 1, see Figures 1 to 4A method for protecting cultural relics in an outdoor construction area. The first step is to construct a cultural relic protection structure: the cultural relic protection structure includes a protective enclosure 2 installed on the cultural relic 1 and a buffer material 3 filled between the protective enclosure and the cultural relic; the buffer material is lightweight ceramsite. Step 2: Install the detection mechanism: The detection mechanism includes several foundation piles 4 fixed to the ground on the side of the protective fence away from the outdoor construction area, several cables 5 connecting the foundation piles to the protective fence, and a display structure 6 set on the cables. The display mechanism is used to prompt and display the offset force generated by the protective fence when the offset distance of the protective fence towards the construction area reaches a set value or more. Step 3: Carry out construction in the outdoor construction area: During the construction process, when the display structure prompts that the offset distance of the protective fence towards the construction area has reached the set value or more, construction is stopped. The soil around and under the cultural relic is reinforced until the offset distance of the protective fence towards the construction area is less than the set value, and construction continues. Step 4: Remove the cultural relic protection mechanism: The soil around and under the cultural relic is reinforced to release the offset force generated by the protective fence as shown by the display mechanism to meet the requirements. The maintenance fence is removed and the buffer material is removed. Before constructing the cultural relic protection structure, the foundation 36 around the cultural relic is leveled and compacted, a concrete ring beam 7 is poured around the cultural relic, and bolts are pre-embedded in the concrete ring beam; the protective enclosure includes protective rings 8 distributed in the vertical direction, and the protective rings include arc-shaped segments 9 that are connected end to end along the circumference of the protective rings. The lowest protective ring is detachably connected to the concrete ring beam by pre-embedded bolts and base nuts. Adjacent arc-shaped segments are detachably connected by arc-shaped segment connecting bolts 10 and arc-shaped segment connecting nuts 11. Adjacent protective rings are detachably connected by protective ring connecting bolts 12 and protective ring connecting nuts 13.The cable includes a first section 14 and a second section 15. The display mechanism includes an insulating sleeve 16, a power supply 17, an indicator light 18 connected at one end to the power supply, a fixed conductive contact 19 connected to the other end of the indicator light, a conductive rod 20 inserted inside the insulating sleeve, a tension gauge 21 located inside the insulating sleeve, and a conductive ring 22 sleeved on the conductive rod. The conductive ring is connected to the other end of the power supply. The conductive ring, indicator light, power supply, and fixed conductive contact are all fixed to the insulating sleeve. The tension gauge connects the insulating sleeve and the conductive rod together. One end of the first section is connected to the protective fence, and the other end is connected to the insulating sleeve. One end of the two sections is connected to the foundation pile, and the other end is connected to the conductive slide rod. When the first and second sections separate, the conductive slide rod extends out of the insulating sleeve. A tension gauge is used to measure the force required to separate the first and second sections. The conductive slide rod is provided with conductive contacts 23. When the conductive slide rod outputs the insulating sleeve, the conductive contacts of the conductive slide rod move towards the fixed conductive contact. When the offset distance of the protective fence towards the construction area reaches the set value, the conductive contacts of the conductive slide rod abut against the fixed conductive contact. At this time, the indicator light illuminates to indicate that the offset distance of the protective fence towards the construction area has reached the set value. The insulating sleeve is provided with a window for observing the reading of the tension gauge. The lower end of the foundation pile is provided with a pointed head 24. The upper end of the foundation pile is provided with a pull hole 25. The foundation pile is provided with several pull-out catches 26 located in the ground during use. The pull-out catches are inclined bar structures with one end away from the foundation pile tilted downwards. In this embodiment, the foundation pile is fixed by first digging a pit, placing the lower end of the foundation pile in the pit, and then filling the pit. After filling, the stop lever is positioned below the ground.

[0025] Example 2 differs from Example 1 in that:

[0026] See Figures 5 to 7The pull-out catch is an inclined bar structure with one end facing upwards, away from the pile. A blind hole penetrating the upper surface of the pile is provided inside the pile. The middle part of the pull-out catch is hinged to the pile via a pivot 27. A partition 28 is provided inside the blind hole, and a vertical screw 29 is threaded onto the partition. The partition divides the blind hole into an upper cavity 30 and a lower cavity 31. The pivot is located in the lower cavity. A clearance hole 32 for the pull-out catch to enter and exit is provided on the side wall of the lower cavity. A lifting block 33 located below the inner end of the pull-out catch and a pressing block 34 located above the inner end of the pull-out catch are provided on the vertical screw. A pull-out catch opening limiting structure is provided in the lower cavity to keep the pull-out catch in an open state. The pull-out catch opening limiting structure includes the lower end wall 35 of the clearance hole and a limiting block 36 located in the lower cavity. The limiting block and the lower end wall of the clearance hole are located on both sides of the pivot. When the vertical screw moves downwards, the pressing block presses down on the inner end of the pull-out catch; when the lifting block descends to its limit position, the pull-out catch is in a position where the torque generated by the pull-out catch's gravity drives the upper end of the pull-out catch to rotate towards the lower cavity around the pivot axis; when the lifting block descends to its limit position and the lower end of the pull-out catch abuts against the lifting block, the torque generated by the pull-out catch's gravity drives the upper end of the pull-out catch to rotate towards the lower cavity around the pivot axis, and the torque generated when the lifting block rises drives the upper end of the pull-out catch to rotate towards the outside of the lower cavity around the pivot axis. When the pull-out catch opens to its limit position, the lower side of the pull-out catch abuts against the lower end wall of the clearance hole, and the upper side abuts against the lower side of the limiting block.
