Description

Technical Field

[0001] This invention relates to the field of mining construction technology, specifically to a construction method for a shallow-buried quick-installation foundation for a raise boring machine. Background Technology

[0002] Raise-the-well rigs are core engineering equipment used in mining construction and underground engineering for drilling vertical passages such as ore passes, risers, and ventilation shafts from bottom to top. During operation, raise-the-well rigs must withstand significant axial drilling pressure, torque, and alternating vibration loads, thus placing high demands on the foundation's bearing capacity, overall structural rigidity, and anti-overturning stability. The construction quality of the rig foundation directly determines the drilling accuracy of the raise-the-well rig and also affects on-site construction safety and the overall project progress.

[0003] In the existing technology, the mainstream foundation construction schemes for riser drilling rig construction sites are mainly divided into two forms: integral concrete pouring foundation and deep buried anchor foundation.

[0004] The first type is a monolithic concrete foundation: This process involves excavating a foundation pit in the construction area, tying a reinforcing cage on-site, and then pouring C25 or C30 grade concrete monolithically. The drilling rig can only be installed after the concrete has cured to the design strength. This construction method has the following main drawbacks: First, it has a long construction period. After the concrete is poured, it typically requires a 7-14 day curing period to reach the design strength, making it difficult to position the drilling rig in time, severely restricting construction efficiency. Second, it consumes a lot of materials and is costly. The concrete consumption for a single drilling rig foundation is generally 15-30 m³, along with a large amount of reinforcing steel, resulting in high material input and construction costs. Third, it cannot be reused. The poured concrete foundation is integrally bonded to the original stratum, requiring demolition by blasting or mechanical crushing after completion. Demolition costs are high, and a large amount of solid construction waste is generated. Fourth, it is limited by site conditions. This foundation requires a high bearing capacity of the original soil, making it difficult to implement in soft soil or narrow working spaces, resulting in poor site adaptability.

[0005] The second method is deep-buried anchoring foundation: This process involves excavating a deep foundation pit and anchoring the raise boring machine base to the ground using pre-embedded anchor bolts or chemical anchors. The disadvantages of this method are: First, it involves a large amount of excavation work. Deep foundation pit excavation is time-consuming and labor-intensive, and the difficulty increases further when encountering hard rock formations. Second, it is highly dependent on geological conditions. If the site is in loose strata, fractured rock zones, or water-rich strata, the deep foundation pit is prone to collapse after excavation, posing a high risk to construction safety. Third, it results in significant component disassembly and assembly losses and low reuse rates. A high percentage of anchor components are damaged during disassembly, and most cannot be reused. Fourth, it hinders rapid equipment relocation. Each change of work site requires re-excavation and anchoring, a cumbersome process that cannot meet the needs of rapid relocation of raise boring machines across multiple work sites.

[0006] In summary, existing lift-drilling rig foundation construction technologies generally suffer from drawbacks such as long construction periods, high construction costs, non-reusable foundation components, poor site geological adaptability, and cumbersome disassembly and assembly operations. Therefore, there is an urgent need in this field to develop a lift-drilling rig foundation construction scheme that features short construction periods, reusability, strong site adaptability, and convenient disassembly and assembly. Summary of the Invention

[0007] The purpose of this invention is to provide a construction method for a shallow-buried quick-installation foundation for a raise boring machine, in order to overcome the above-mentioned shortcomings in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A construction method for a shallow-buried quick-assembly foundation for a raise boring machine includes the following steps: S1, Site preparation: Select a solid foundation, remove surface soil, gravel, and debris from the construction site, and level the site to create a flat surface suitable for the shallow-buried foundation; S2, Foundation prefabrication: Hoist the prefabricated quick-assembly foundation module into position on the leveled construction site. The quick-assembly foundation module is a prefabricated steel structure ground beam base; anchor the quick-assembly foundation module to the foundation using several anchors, and assemble reinforcing plates on the quick-assembly foundation module to improve the overall bearing capacity of the foundation; S3, Secondary grouting for shallow-buried fixation: Pour concrete or grout into the bottom and surrounding area of ​​the quick-assembly foundation module to achieve... Shallow burial and grouting fill the gap between the quick-assembly foundation module and the foundation, forming an integral load-bearing structure with the quick-assembly foundation module and anchors; S4, Drilling rig installation and leveling: The raise boring machine base is detachably assembled onto the top surface of the quick-assembly foundation module using connecting cylinders or bolts. The levelness and overall stability of the drilling rig are checked and adjusted to ensure that the drilling rig meets the accuracy requirements of the drilling operation; S5, Post-construction disassembly and relocation: After the raise boring operation is completed, the raise boring machine is dismantled first, then the anchors are loosened or pulled out, and the quick-assembly foundation module is lifted away from the construction site; the shallow pit formed by the construction is backfilled to restore the original appearance of the site; the disassembled and recycled quick-assembly foundation module and anchors can be reused in the next construction site.

[0010] In the above-mentioned construction method for a shallow-buried quick-installation foundation for a raise boring machine, in step S2, the anchor is one or more combinations of expansion bolts, wedges, and steel sleeves, and the corresponding type of anchor is selected according to the geological conditions of the construction site.

[0011] In the above-mentioned construction method for a shallow-buried quick-assembly foundation for a raise boring machine, in step S2, the quick-assembly foundation module is an integral steel structure or a segmented assembly module composed of multiple components assembled with bolts; the segmented assembly module facilitates transportation and on-site hoisting operations.

[0012] In the above-mentioned construction method for a shallow-buried quick-installation foundation for a raise boring machine, in step S1, the burial depth of the shallow foundation is adjusted according to the geological conditions to match the shallow pit depth and the thickness of the cushion layer; a smaller burial depth is used with a thin cushion layer in hard rock formations; a medium burial depth is used with a conventional cushion layer in medium hard formations; and a larger burial depth is used with a thicker cushion layer in soft formations, while simultaneously increasing the density of the anchorage.

[0013] In the above-mentioned construction method of a shallow-buried quick-installation foundation for a raise boring machine, in step S4, a number of elongated oval-hole bolt seats are pre-set on the top surface of the quick-installation foundation module; the raise boring machine base is connected to the quick-installation foundation module by means of bolts passing through the elongated oval holes; the elongated oval hole structure can realize the fine adjustment of the horizontal position of the drilling machine base during the installation stage, ensuring the installation accuracy of the drilling machine.

[0014] The above-mentioned construction method for a shallow-buried quick-installation foundation for a raise boring machine includes a secondary grouting process in step S3 using fast-setting concrete or grouting material. After grouting is completed, the drilling machine installation process in step S4 can be carried out without waiting for curing to the design strength. The overall construction cycle from site preparation in step S1 to drilling machine installation in step S4 is 1-2 days.

[0015] In the above-mentioned construction method for a shallow-buried quick-installation foundation for a reverse drilling rig, the total time for rig dismantling and foundation recycling in step S5 is no more than 8 hours, and the component recycling rate of the quick-installation foundation module and anchor is no less than 90%.

[0016] The above-mentioned construction method for a shallow-buried quick-installation foundation for a reverse drilling rig is applied to the rapid erection and dismantling of the rig foundation in reverse drilling projects for mine chutes, risers, and ventilation shafts.

[0017] The above-mentioned construction method for a shallow-buried quick-installation foundation for a reverse drilling rig allows the foundation to be adapted to at least one of the following construction conditions: hard rock formations, medium-hard strata, soft strata, narrow construction sites, and permafrost areas, by adjusting the type, quantity, spacing, and thickness of the anchors and the cushion layer.

[0018] In the above-mentioned construction method for a shallow-buried quick-installation foundation for a raise boring machine, in step S2, the quick-installation foundation module has several anchor holes, and the anchors pass through the anchor holes to fix the quick-installation foundation module to the foundation; the number and spacing of the anchor holes are designed according to the raise boring machine model and the maximum axial drilling pressure of the drilling machine.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention has a short construction cycle and high work efficiency. Traditional concrete foundations require a curing period of 7-14 days before they can be put into use. This solution uses precast steel structure ground beam modules in conjunction with a secondary grouting process. From site preparation to drilling rig installation, it only takes 1-2 days. Compared with the traditional solution, the construction cycle can be shortened by 60%-80%, which greatly improves the efficiency of drilling rig entry and operation on site.

[0021] 2. The components of this invention are recyclable and have low engineering costs. The quick-assembly foundation module uses prefabricated steel structure components, and the entire ground beam base can be reused at least 10 times. The components can be recycled and reused after disassembly and assembly, reducing the consumption of disposable materials such as concrete and steel bars, and effectively reducing the overall cost of the project.

[0022] 3. The present invention has strong adaptability to working conditions and geological conditions. This scheme is a shallow buried foundation structure, which has low requirements for the original foundation conditions. By adjusting the anchor type, layout parameters and cushion layer thickness, it can be adapted to hard rock layers, medium hardness layers and soft layers. At the same time, it can meet the construction needs of various complex working conditions such as narrow construction sites and permafrost areas.

[0023] 4. This invention is easy to disassemble and relocate, generates less construction waste, and the components are connected by bolts for easy disassembly. No blasting or mechanical crushing is required after the project is completed. The drilling rig disassembly and foundation recycling operations can be completed within 4-8 hours. The recycling rate of foundation modules and anchor components is not less than 90%, which reduces the generation of construction waste and facilitates the rapid relocation of the drilling rig to multiple work sites.

[0024] 5. The installation accuracy of this invention is easy to ensure. The top surface of the quick-installation base module is equipped with an elongated hole bolt seat.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1-2 The present invention will be described in further detail below.

[0029] This invention provides a construction method for a shallow-buried quick-installation foundation for a raise boring machine, comprising the following steps: S1, Site preparation: Selecting a solid foundation, removing surface soil, gravel, and debris from the construction site, and leveling the site to form a flat surface suitable for the shallow-buried foundation; S2, Foundation prefabrication: Hoisting the prefabricated quick-installation foundation module into position on the leveled construction site, wherein the quick-installation foundation module is a prefabricated steel structure ground beam base; using several anchors to anchor the quick-installation foundation module to the foundation, and assembling reinforcing plates on the quick-installation foundation module to improve the overall bearing capacity of the foundation; S3, Secondary grouting for shallow-buried fixing: Pouring concrete or other grouting methods into the bottom and surrounding area of ​​the quick-installation foundation module. The grouting material achieves shallow burial fixation, filling the gap between the quick-assembly foundation module and the foundation, making the quick-assembly foundation module, anchors, and foundation form an integral load-bearing structure; S4, Drilling rig installation and leveling: The raise boring machine base is detachably assembled to the top surface of the quick-assembly foundation module through connecting cylinders or bolts, and the levelness and overall stability of the drilling rig are checked and adjusted to ensure that the drilling rig meets the accuracy requirements of drilling operations; S5, Disassembly and relocation after construction: After the raise boring operation is completed, the raise boring machine is first dismantled, then the anchors are loosened or pulled out, and the quick-assembly foundation module is lifted away from the construction site; the shallow pit formed by the construction is backfilled to restore the original appearance of the site; the disassembled and recycled quick-assembly foundation module and anchors can be reused in the next construction site.

[0030] Specifically, in step S2, the anchor is one or more combinations of expansion bolts, wedges, and rebar sleeves, with the appropriate type of anchor selected based on the geological conditions of the construction site. In step S2, the quick-assembly foundation module is an integral steel structure or a segmented assembly module composed of multiple components bolted together; the segmented assembly module facilitates transportation and on-site hoisting operations. In step S1, the burial depth of the shallow foundation is adjusted according to geological conditions, matching the shallow pit depth and the thickness of the cushion layer; a smaller burial depth with a thin cushion layer is used in hard rock formations; a medium-hardness stratum uses a medium burial depth with a conventional cushion layer; and a soft stratum uses a larger burial depth with a thicker cushion layer, while simultaneously increasing the density of the anchor placement. In step S4, the top surface of the quick-assembly foundation module has several pre-set elongated hole bolt seats; the raise boring machine base is connected to the quick-assembly foundation module via bolts passing through these elongated holes; the elongated hole structure allows for fine-tuning of the horizontal position of the drilling rig base during installation, ensuring the drilling rig installation accuracy. In step S3, the secondary grouting uses fast-setting concrete or grouting material.

In step S5, the total time for drilling rig dismantling and foundation recycling is no more than 8 hours, and the component recycling rate of the quick-assembly foundation module and anchor is no less than 90%.

[0031] It should be noted that the construction method described herein is applied to the rapid erection and dismantling of drilling rig foundations in mine chutes, raises, and ventilation shaft raise drilling projects. By adjusting the type, quantity, spacing, and thickness of the anchoring elements, the foundation can be adapted to at least one of the following construction conditions: hard rock formations, medium-hard strata, soft strata, narrow construction sites, and permafrost areas. In step S2, the quick-installation foundation module has several anchoring holes, through which anchoring elements are passed to fix the quick-installation foundation module to the ground; the number and spacing of the anchoring holes are designed based on the raise drilling rig model and the maximum axial drilling pressure of the drilling rig.

[0032] In this invention, the specific embodiments of the invention will be described in detail and in complete form below in combination with different construction conditions. Each embodiment strictly follows the core construction technology of this invention, and the parameters are adjusted differently for different geological and site conditions.

[0033] Example 1: Construction in an open area with hard rock strata (hard rock strata such as granite and limestone)

[0034] This embodiment is applied to the reverse drilling construction of ventilation shafts in deep, hard rock formations in mines. The construction site is open, the strata have high bearing capacity, and there are no weak interlayers. The specific construction steps are as follows: S1, Site treatment: Select a complete hard granite rock foundation, manually remove the thin layer of loose soil, gravel and debris from the surface of the site, without the need for large-scale deep excavation, only leveling and grinding the construction area to create a flat placement surface; according to the working conditions of hard rock strata, a shallow burial depth design is adopted, with the shallow pit depth controlled at 10-15cm, and a 3-5cm thin gravel cushion layer is laid, without the need for thickening or reinforcement, utilizing the high strength bearing characteristics of the rock strata itself to meet the foundation stress requirements. S2. Foundation Precast Component Placement: An integral steel structure quick-assembly foundation module is selected. The integral structure offers high rigidity and no splicing gaps, making it suitable for high drilling pressure operations with large raise boring rigs. Eight sets of anchoring holes are designed based on the maximum axial drilling pressure of the drilling rig, evenly and symmetrically distributed. Single expansion bolts are used as anchors, suitable for the anchoring characteristics of drilling in hard rock formations. The expansion bolts are driven into the rock formation through the anchoring holes and locked in place, completing the foundation module anchoring. Subsequently, reinforcing steel plates are welded and assembled on the top surface of the foundation to improve its overall vibration resistance. S3. Secondary Grouting and Shallow Burial Fixing: Rapid-hardening cement grouting material is used for grouting, focusing on filling the tiny gaps between the bottom of the foundation module and the rock formation. The grouting is full, dense, and the surface is smooth. After grouting, the surface is left to stand for 2-3 hours to allow the grout to reach early stable strength. No standard curing period is required; the drilling rig installation process can proceed directly. S4. Drill Rig Installation and Leveling: Using the pre-set elongated hole bolt seats on the top surface of the foundation, the raise boring machine base is installed. The horizontal position of the drilling rig is finely adjusted left and right and forward and backward through the elongated holes. With the help of a high-precision level, the horizontal error of the drilling rig is controlled within ±0.5mm, and the verticality error is controlled within 0.1%, ensuring that the drilling accuracy meets the standards. S5. Post-Construction Dismantling and Relocation: After the raise boring is completed, the entire drilling rig is dismantled within 4 hours. Then, all expansion bolts are loosened, and the steel structure foundation module is hoisted and moved away. The entire process takes 6 hours. The 10cm shallow pit is backfilled and compacted with original rock and gravel to completely restore the original appearance of the site. The component recovery rate of this construction is 98%. All core components are undeformed and undamaged, and can be directly used for the next construction site in hard rock strata.

[0035] The overall construction period of this embodiment is 1 day, which is more than 90% shorter than the traditional construction period of more than 10 days for concrete foundations, and the construction efficiency is greatly improved.

[0036] Example 2: Construction in conventional sites for medium-hardness formations (mixed sandstone and mudstone formations)

[0037] This embodiment is applied to the construction of a mine riser drilling project. The construction site is regular, and the strata are a medium-hardness mixed sandstone and mudstone strata with moderate bearing capacity and no significant risk of settlement. The specific construction steps are as follows: S1. Site preparation: Mechanical and manual removal of surface soil and loose rock layers is carried out to precisely level the site. A medium burial depth design is adopted, with the shallow pit depth controlled at 20-25cm. An 8-10cm conventional sand and gravel cushion layer is laid and compacted to ensure uniform stress on the base surface. S2. Foundation prefabrication: A segmented assembly quick-assembly foundation module is selected. Four steel structure components are assembled on-site into an integral base using high-strength bolts. During the assembly process, the flatness is calibrated to ensure that there is no warping. Twelve sets of anchoring holes are designed according to the drilling pressure parameters of a medium-sized drilling rig and are evenly distributed. The anchoring devices adopt a combination of expansion bolts and wedges to improve the anchoring stability of the medium-hardness strata and prevent slight slippage of the foundation. After assembly, side reinforcement plates and top reinforcement plates are installed to strengthen the overall bearing structure of the foundation. S3. Secondary Grouting and Shallow Burial Fixation: Fast-setting micro-expansion concrete is used for grouting to fill the gaps at the bottom and around the foundation. The concrete sets quickly and exhibits no shrinkage deformation, effectively ensuring the integrity of the foundation and subgrade. After grouting, the rig can be installed after 4 hours of settling, requiring no long-term maintenance. S4. Drill Rig Installation and Leveling: The drilling rig's installation position is fine-tuned using the foundation's elongated hole bolt seats. Multiple checks and calibrations of levelness and stability are performed to eliminate installation errors caused by assembly gaps, ensuring the drilling rig fully meets the accuracy requirements for drilling operations. S5. Post-Construction Dismantling and Relocation: After drilling operations are completed, the drilling rig is dismantled, anchors are removed, and foundation modules are disassembled and hoisted within 7 hours, achieving a component recovery rate of 95%. The shallow pits are backfilled and compacted in layers, completely restoring the site's flatness and topography to their original state. The overall construction cycle of this embodiment is 1.5 days, significantly higher than traditional methods.

[0038] Example 3: Construction in narrow sites with weak strata (silty clay, loose and broken strata)

[0039] This embodiment is applied to the construction of shallow mine chute raise boring. The construction site is narrow, and the stratum is a loose and weak silty clay layer with low bearing capacity, easy settlement and deformation, making construction difficult. The specific construction steps are as follows: S1, Site treatment: Thoroughly remove the surface soft loose soil and unstable soil layers; adopt a deep burial design, with the shallow pit depth controlled at 30-35cm, and lay a 15cm thick graded sand and gravel cushion layer, compacting it in layers to improve the overall bearing capacity and anti-settlement capacity of the site base. S2, Foundation prefabrication component placement: Due to the limited hoisting space in the narrow site, segmented assembly quick-assembly foundation modules are selected, and the assembly operation can be completed by small on-site equipment; according to the bearing characteristics of the weak stratum, the anchoring hole layout is densified, with 16 sets of anchoring holes set and the spacing between them reduced; the anchoring components adopt a composite anchoring structure of steel sleeve + expansion bolt, which greatly improves the anchoring depth and anchoring tension, preventing foundation settlement and displacement; reinforced plates are installed in all directions to strengthen the foundation's resistance to deformation and vibration. S3. Secondary Grouting and Shallow Burial Fixation: High-strength, fast-hardening grout is used for full-filling operations, completely filling the bottom, perimeter, and anchor hole gaps of the foundation. The integral structure formed after the grout has solidified disperses the stress load on the soft stratum and inhibits foundation settlement and deformation. S4. Drilling Rig Installation and Leveling: High-precision fine-tuning is performed using an elongated hole structure, and the horizontal and vertical alignment of the drilling rig is calibrated multiple times to offset the effects of slight stress deformation in the soft stratum, ensuring stable accuracy throughout the drilling process. S5. Post-Construction Dismantling and Relocation: All dismantling and hoisting operations are completed within 8 hours after construction, with a component recovery rate of 92%. For deep excavations and shallow pits, layered backfilling with lime-soil and layered compaction are used to avoid later site settlement problems and fully restore the site's usability. The overall construction cycle of this embodiment is 2 days, solving the technical problems of traditional foundations being unable to be stably constructed in soft strata and being prone to failure.

[0040] Example 4: Construction under special conditions in permafrost regions

[0041] This embodiment is applied to the construction of mine ventilation shafts in high-altitude permafrost areas. The strata are characterized by freeze-thaw cycles, loose soil, and unstable bearing capacity. The core optimization scheme for the specific construction is as follows: during the site treatment stage, a moderate burial depth is maintained, and an antifreeze sand and gravel cushion layer is laid; the anchors adopt a steel sleeve extended anchoring structure to penetrate deep into the permafrost stable layer; the foundation module adopts an anti-corrosion steel structure to avoid freeze-thaw corrosion; the grouting uses an antifreeze fast-hardening grouting material that is suitable for low-temperature curing environment. The remaining construction steps are consistent with those for conventional strata, which can realize rapid construction, stable operation, and cyclic reuse of drilling rig foundations in permafrost areas, filling the gap in the adaptation of existing technologies to permafrost conditions.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
