Description

Technical Field

[0001] The invention relates to the technical field of building foundation pit construction equipment, in particular to an umbrella-shaped grouting recoverable anchor cable foundation pit combined supporting structure and a construction method thereof. Background Art

[0002] With the continuous development of economic construction, the development of underground space is becoming more and more popular, and the number of foundation pits is increasing. The country's awareness of environmental protection is constantly improving, and the problems existing in traditional support projects are gradually exposed. After the support components complete their support functions, they are directly buried in the soil and cannot be recycled, resulting in material waste and soil pollution, which seriously affects the construction of subsequent buildings, especially the construction of urban subways and underground shopping malls. If the traditional support structure is replaced with a recyclable support structure, it will reduce construction costs, save resources, and reduce pollution. The environmental pollution and air pollution caused by the construction of traditional support structures need to be solved urgently. It is necessary to develop a new foundation pit slope combined support structure system to achieve recycling and reuse, and the construction process will not cause environmental pollution.

[0003] The utility model with publication number CN214695652U discloses a novel deep foundation pit slope support structure. By setting an installation mechanism, the second moving block moves downward to push the two groups of trapezoidal blocks to move away from each other, thereby pushing the fixed block to move upward into the honeycomb panel, so that the second spring is no longer subjected to the extrusion force to recover and push the fixed card block to rotate and engage in the card slot of the honeycomb panel to fix the honeycomb panel. Through the cooperation of the above multiple parts, the honeycomb panel can be quickly installed.

[0004] The utility model with publication number CN208039281U discloses a new type of deep foundation pit slope support structure, which ensures the safety of buildings around the foundation pit, and does not harm the buildings due to deformation, subsidence, collapse or displacement of the soil during the excavation of the foundation pit and the construction of underground projects. The water in the original soil enters the drainage pipe after passing through the composite water filter layer, and then is discharged. The composite water filter layer is permeable and prevents soil from entering the drainage pipe, thus ensuring the smooth flow of the drainage pipe.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 11 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problems that most of the recyclable devices proposed in the prior art have complex structures, difficult recycling, unsafe recycling, etc., cannot be safely and reliably used in temporary construction pits, have a small scope of application, and are relatively poor in practicality, the following scheme is disclosed, including that the top and bottom of the slope of the slope body 1 both start to have longitudinal drainage ditches 4, and the slope on both sides of the drainage ditch 4 is 5%. The supporting structure includes transverse steel strips 5 and longitudinal steel strips 6, and the transverse steel strips 5 and the longitudinal steel strips 6 are arranged in a staggered structure, and the intersections of the transverse steel strips 5 and the longitudinal steel strips 6 are provided with assembled recyclable panels 7, and the length × width × height of the assembled recyclable panels 7 is 50cm × 50cm × 3cm.

[0029] First, when the supporting structure needs to be recycled, it is only necessary to remove the recyclable anchor cable 10 from the lower part of the slope main body 1 to the upper part. Then, when all the recyclable anchor cables 10 are removed, the assembled recyclable panel 7 and the transverse steel strips 5 and the longitudinal steel strips 6 are disassembled and recycled from the lower part of the slope main body 1 to the upper part in turn. At the same time, the soil nails 3 at the bottom of the slope are disassembled and then the soil nails 3 at the top of the slope are disassembled. Then, the flexible surface layer 2 can be rolled up, thereby achieving the purpose of recycling the flexible surface layer 2, until all components are recycled.

[0030] Embodiment 2: Different from Embodiment 1, this embodiment can improve the durability and sun protection ability of geotextile, meet the characteristics of drainage, support and durability, and facilitate recycling. For details, please refer to Figure 1-Figure 2, a slope surface body 1 and a flexible surface layer 2 arranged on the surface of the slope surface body 1; it also includes: the flexible surface layer 2 is a flexible surface layer 2 that combines geotextile and sun-proof cloth, and the geotextile is located under the sun-proof cloth and is close to the foundation pit slope, and the sun-proof cloth is combined with the geotextile by sewing; the upper and lower ends of the flexible surface layer 2 are respectively located at the top and bottom of the slope, and at the same time, the upper and lower ends of the flexible surface layer 2 are respectively fixed to the slope surface body 1 by soil nails 3, and a supporting structure is arranged on the front side of the flexible surface layer 2.

[0031] A flexible surface layer 2 is laid on the main body 1 of the slope. The materials used for the flexible surface layer 2 are geotextile and sun-proof cloth. The two are combined by sewing. At the same time, the upper and lower ends of the flexible surface layer 2 are fixed by soil nails 3. The soil nails 3 are nailed into the main body 1 of the slope, so that the upper and lower ends of the flexible surface layer 2 are fixed to the top and bottom of the slope. In addition, drainage ditches 4 are opened at the top and bottom of the slope main body 1 to achieve drainage effect, thereby avoiding direct erosion of rainwater and reducing soil erosion. The surface layer combining geotextile and sun-proof cloth can improve the durability and sun-proof ability of the geotextile, meet the characteristics of drainage, support and durability, and facilitate recycling.

[0032] Embodiment 3: Different from Embodiment 2, this embodiment not only saves costs, but also reduces waste of resources, avoids irreversible pollution of underground space by unrecovered anchor cables, and reduces the impact on the environment. Figure 2-Figure 6 The assembled recyclable panel 7 is fixed by connecting screws 8 and the transverse steel strips 5 and the longitudinal steel strips 6. At the same time, an anchor hole 9 is opened on the surface of the assembled recyclable panel 7. The diameter of the anchor hole 9 is 35 mm, and a recyclable anchor 10 is fixed inside the anchor hole 9, and the rear end of the recyclable anchor 10 extends to the inside of the slope body 1. The recyclable anchor 10 adopts the second-generation extruded anchor type recyclable anchor 10, and the recyclable anchor 10 has a nominal diameter of 32 mm, and the full free section is grouted, and concrete mortar and fluidized solidified loess can be used as grouting materials.

[0033] Fluidized solid loess material is made of loess, coal gangue, carbide slag, slag and alkali activator. It has a good bonding effect with steel bars and soil, replacing traditional concrete grouting and is more environmentally friendly. Because its material is composed of loess and various solid wastes, it will not cause pollution if it remains inside the soil after the anchor cable is recovered.

[0034] Then, the transverse steel strips 5 and the longitudinal steel strips 6 are staggeredly installed on the surface of the flexible surface layer 2, and then the assembled recyclable panel 7 is installed at the intersection of each group of transverse steel strips 5 and longitudinal steel strips 6, so as to achieve the effect of fixing the transverse steel strips 5 and the longitudinal steel strips 6. At the same time, an anchor hole 9 is opened in the middle of the assembled recyclable panel 7, and the anchor hole 9 can be used for the recyclable anchor 10 to penetrate into the slope body 1. Through the setting of the recyclable anchor 10, the rock and soil body is reinforced and the structure is fixed. The recyclable anchor 10 not only saves costs and reduces the waste of resources, but also avoids the irreversible pollution of the underground space caused by the unrecovered anchor, and reduces the impact on the environment. After the transverse steel strips 5, the longitudinal steel strips 6 and the recyclable anchor 10 are recycled, they only need to be inspected, repaired and maintained before they can be used again.

[0035] Embodiment 4: Different from Embodiment 3, the recyclable anchor cable 10 in this embodiment is fixedly installed inside the slope main body 1 to ensure the stability of the connection and the loosening and falling off caused by soil erosion. The rear end of the recyclable anchor cable 10 is fixedly provided with a positioning connecting rod 11, and the rear end of the positioning connecting rod 11 is fixedly connected to the front end of the elastic telescopic rod 12, and the rear end of the elastic telescopic rod 12 is fixedly connected to the middle part of the positioning disk body 13, and the rear end of the positioning disk body 13 is fixedly installed with a lifting threaded rod 14, and the rear end of the lifting threaded rod 14 is threadedly connected to the inside of the abutment limit head 15.

[0036] The outside of the positioning disc body 13 is hingedly connected to the rear end of the flip positioning frame 16 at equal angles, and the inner side of the front end of the flip positioning frame 16 set at equal angles is hingedly connected to the outer end of the flip limiting rod 17, and the inner end of the flip limiting rod 17 set at equal angles is hingedly connected to the outside of the support disc body 18, and the support disc body 18 is fixedly installed on the front end outside of the elastic telescopic rod 12; the outside of the flip positioning frame 16 set at equal angles is fitted and installed on the inside of the interference limit head 15, and after the interference limit head 15 connected by a rotating thread approaches the positioning connecting rod 11, the interference limit head 15 drives the flip positioning frame 16 to flip inward for storage, and after the flip positioning frame 16 is flipped outward, the recyclable anchor cable 10 is fixedly installed on the inside of the slope body 1.

[0037] like Figure 7-10 As shown, when the retrievable anchor cable 10 needs to be fixedly installed with the slope main body 1, the flip positioning frame 16 and the flip limit rod 17 at the rear end of the retrievable anchor cable 10 are in a storage state, and then the retrievable anchor cable 10 and the positioning connecting rod 11 at the rear end thereof and the interference limit head 15 are inserted into the interior of the slope main body 1, so that the interference limit head 15 is locked inside the slope main body 1.

[0038] By manually rotating the retractable anchor cable 10, the positioning disc body 13 at its rear end drives the fixedly connected lifting threaded rod 14 to rotate, and the locked interference limit head 15 does not follow the rotation, so that the positioning disc body 13 gradually moves to the outside of the interference limit head 15, and then the positioning disc body 13 drives the flip positioning frame 16 hinged at the outer end to follow the movement and is not interfered by the interference limit head 15, so that the flip positioning frame 16 flips outward and is supported by the flip limit rod 17 hinged by the support disc body 18, thereby ensuring the stability of the flip positioning frame 16 installed inside the slope body 1.

[0039] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
