[0002] The inclined shaft of a tunnel is an auxiliary tunnel connecting the ground and the tunnel at a preset inclination angle, mainly used to solve the problems of long ventilation distance and insufficient operation surface in long tunnel construction. Its core functions include realizing multi-section synchronous construction to shorten the construction period by increasing the operation surface, and being used as a ventilation channel during the construction period and the operation period. The cross partition is an internal support and separation structure applied in the inclined shaft engineering, mainly composed of vertical partitions and horizontal partitions intersecting to form a "cross" layout.

However, when the cross partition is integrally poured, a complex cross formwork needs to be used for pouring, and a full-frame support needs to be built during the process, which consumes a lot of materials, prolongs the construction period, and is low in efficiency. SUMMARY

[0009] In a second aspect, the present invention provides a construction method for an inclined shaft cross diaphragm, used for constructing the inclined shaft cross diaphragm structure described in the present invention, comprising the following steps: S1: Construct the vertical reinforcement cage of the vertical partition along the length of the inclined shaft; S2: The vertical steel reinforcement cage is poured to form the vertical partition; S3: Prefabricate the prefabricated block, and then install the prefabricated block on the vertical partition to form the horizontal partition.

[0010] Preferably, in S1, reinforcement bars are first installed at the top and bottom of the inclined shaft along the centerline of the inclined shaft; After the rebar installation is completed, the vertical rebar cage is tied along the length of the inclined shaft using an operating trolley, and the vertical rebar cage is connected to the rebar installation.

[0011] Preferably, the operating trolley includes a main frame and an operating platform disposed on the main frame, with at least three layers of the operating platform disposed along the height direction of the main frame; The main frame is equipped with a first roller at its bottom.

[0012] Preferably, in S2, a formwork trolley is used to pour the vertical steel reinforcement cage in sections. After pouring one section, the formwork trolley moves to the next section for operation.

[0013] Preferably, the template trolley includes two longitudinally arranged portal frames and two longitudinally arranged first templates, with one first template (202) connected to the inner side of each portal frame. The two first templates can move closer to or further away from each other, and the vertical steel reinforcement cage is located between the two first templates.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0029] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0030] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are set as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," "parallel," or "coaxial" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0031] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0032] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as 2, 3, 4, 5, 6, 7, 8, or 9, and can even exceed nine.

[0033] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0034] Example 1 like Figures 1-5 As shown, this embodiment discloses a cross-shaped partition structure for inclined shafts, comprising: Vertical partition 1 is located inside the inclined shaft 100 and is arranged along the length of the inclined shaft 100; The horizontal partitions 2 are located on both sides of the vertical partition 1. The horizontal partitions 2 include several prefabricated blocks 21. One end of the prefabricated block 21 is connected to the vertical partition 1 through the first snap-fit ​​3, and the other end of the prefabricated block 21 is connected to the side wall of the inclined shaft 100 through the second snap-fit ​​4.

[0035] In the inclined shaft cross diaphragm structure described in this embodiment, the transverse diaphragm 2 is constructed using a prefabricated block splicing method. One end of the prefabricated block 21 is connected to the vertical diaphragm 1 via a first snap-fit ​​3, and the other end of the prefabricated block 21 is connected to the side wall of the inclined shaft 100 via a second snap-fit ​​4. This allows the prefabricated block 21 to be installed on the vertical diaphragm 1 and the side wall of the inclined shaft 100, enabling rapid installation of the transverse diaphragm 2. This effectively reduces the construction difficulty of the cross diaphragm, simplifies the on-site construction process, reduces the difficulty of formwork support, and effectively improves the construction efficiency of the cross diaphragm.

[0036] In this embodiment, the transverse partition 2 is constructed using prefabricated blocks, eliminating the need for formwork within the inclined shaft 100. Only the vertical partition 1 needs to be formworked and poured within the inclined shaft 100. Prefabricated blocks 21, which are prefabricated off-site, are then transported into the inclined shaft 100 and installed on the vertical partition 1 and the side wall of the inclined shaft 100. By installing multiple prefabricated blocks 21, the transverse partition 2 is formed, avoiding the need for formwork to be erected within the inclined shaft 100. This simplifies the formwork construction process, reduces the use of full-span scaffolding, and significantly reduces the number of formwork and scaffolding, effectively saving construction costs and accelerating the construction progress.

[0037] In one or more implementations, such as Figure 3 As shown, the first snap-fit ​​component 3 includes a first bending plate 31, and the first bending plate 31 is provided with the top and bottom surfaces of the precast block 21; One end of the first bent plate 31 is connected to the vertical partition 1, and the other end of the first bent plate 31 is connected to the precast block 21.

[0038] The precast block 21 is fixed by the first bending plate 31 being symmetrically arranged on the top and bottom surfaces of the precast block 21 to form a double fixation, so that the precast block 21 is connected to the vertical partition 1. Specifically, the first bent plate 31 includes two interconnected first side plates. One first side plate abuts against the top or bottom surface of the precast block 21 and is then fixed by bolts. The other first side plate abuts against the side of the vertical partition 1 and is also fixed by bolts. During construction, one end of the precast block 21 is first abutted against the side of the vertical partition 1, and the other end of the precast block 21 is abutted against the side wall of the inclined shaft 100. Then, the first snap-fit ​​component 3 is installed at the junction of the precast block 21 and the vertical partition 1, specifically as follows: A first bending plate 31 is provided on both the top and bottom surfaces of the precast block 21. The first bending plate 31 is composed of two first side plates, and the included angle between the first side plates is equal to the included angle between the precast block 21 and the vertical partition 1. On the top surface of the precast block 21, one first side plate of the first bending plate 31 abuts against the top surface of the precast block 21 and is then fixed with bolts, while the other first side plate abuts against the side wall of the vertical partition 1 and is then fixed with bolts. On the bottom surface of the precast block 21, one first side plate of the first bending plate 31 abuts against the bottom surface of the precast block 21 and is then fixed with bolts, while the other first side plate abuts against the side wall of the vertical partition 1 and is then fixed with bolts.

[0039] In one or more implementations, such as Figure 4 As shown, the second snap-fit ​​component 4 includes a second bending plate 41, which is disposed on the top and bottom surfaces of the precast block 21. One side of the second bent plate 41 is connected to the end of the precast block 21 away from the first snap-fit ​​3, and the other side of the second bent plate 41 is connected to the side wall of the inclined shaft 100. The precast block 21 is fixed by symmetrically setting the second bending plate 41 on the top and bottom surfaces of the precast block 21 to form a double fixation, so that the precast block 21 is connected to the side wall of the inclined shaft 100. Specifically, the second bending plate 41 includes two interconnected second side plates. One second side plate abuts against the top or bottom surface of the precast block 21 and is then fixed by bolts. The other second side plate abuts against the side wall of the inclined shaft 100 and is also fixed by bolts. During construction, one end of the precast block 21 is first abutted against the side of the vertical partition 1, and the other end of the precast block 21 is abutted against the side wall of the inclined shaft 100. Then, the second fastener 4 is installed at the junction of the precast block 21 and the side wall of the inclined shaft 100. Specifically: A second bending plate 41 is provided on both the top and bottom surfaces of the precast block 21. The second bending plate 41 consists of two second side plates, and the included angle between the second side plates is equal to the included angle between the precast block 21 and the side wall of the inclined shaft 100. On the top surface of the precast block 21, one second side plate of the second bending plate 41 abuts against the top surface of the precast block 21 and is then fixed with bolts, while the other second side plate abuts against the side wall of the inclined shaft 100 and is then fixed with bolts. On the bottom surface of the precast block 21, one second side plate of the second bending plate 41 abuts against the bottom surface of the precast block 21 and is then fixed with bolts, while the other second side plate abuts against the side wall of the inclined shaft 100 and is then fixed with bolts.

[0040] In an embodiment, such as Figure 5As shown, one end face of the precast block 21 is flat so that it can fit tightly against the side of the vertical partition 1, and the other end face of the precast block 21 is curved, which is adapted to the side wall of the inclined shaft 100 so that it can fit tightly against the side wall of the inclined shaft 100.

[0041] In an optional embodiment, the precast block 21 is a reinforced concrete slab with multiple lifting rings on its top surface. When installing the precast block 21 in the inclined shaft 100, the precast block 21 is lifted by a truck crane from bottom to top, keeping the precast block 21 in a horizontal position until the precast block 21 abuts against the side of the vertical partition 1 and the side wall of the inclined shaft 100 respectively. Then, the first snap-fit ​​3 and the second snap-fit ​​4 are installed to fix the precast block 21. Multiple precast blocks 21 are lifted in sequence, with the sides of adjacent precast blocks 21 abutting against each other.

[0042] In optional implementations, such as Figure 3 As shown, the two first bent plates 31 located on the top and bottom surfaces of the precast block 21 are connected by a first fixing bolt 32, wherein the first fixing bolt 32 passes through the precast block 21 and is connected to the two first bent plates 31. Furthermore, such as Figure 4 As shown, the two second bent plates 41 located on the top and bottom surfaces of the precast block 21 are connected by a second fixing bolt 42, wherein the second fixing bolt 42 passes through the precast block 21 and is connected to the two second bent plates 41. Furthermore, such as Figure 3 As shown, the first bent plates 31 located at the same height on both sides of the vertical partition 1 are connected by a third fixing bolt 33. The first fixing bolt 32 passes through the vertical partition 1 and is connected to the two first bent plates 31.

[0043] Example 2 like Figures 1-9 As shown, this embodiment discloses a construction method for an inclined shaft cross diaphragm, used for constructing the inclined shaft cross diaphragm structure described in Embodiment 1, including the following steps: S1: Construct a vertical steel reinforcement cage 11 for the vertical partition 1 along the length of the inclined shaft 100; S2: The vertical steel cage 11 is poured to form the vertical partition 1; S3: Prefabricate horizontal slab prefabricated blocks 21, and then install the horizontal slab prefabricated blocks 21 on the vertical partition 1 to form a horizontal partition 2.

[0044] The construction method described in this implementation involves first constructing a vertical steel cage 11, then pouring concrete to form a vertical partition 1, and finally installing precast blocks 21 to form a horizontal partition 2 on the vertical partition 1, thus completing the cross partition work of the inclined shaft 100. Compared with the traditional method of pouring the cross partition as a whole by using formwork, the method of first constructing the vertical partition 1 and then installing precast blocks 21 to form the horizontal partition 2, which combines prefabrication and cast-in-place construction, not only improves the construction efficiency of the cross partition but also reduces the formwork materials required for construction and lowers the difficulty of formwork support, thereby greatly improving construction efficiency.

[0045] In one or more embodiments, in S1, reinforcement bars are first installed at the top and bottom of the inclined shaft 100 along the centerline of the inclined shaft 100. After the rebar installation is completed, the vertical rebar cage 11 is tied along the length of the inclined shaft 100 using the operating trolley 10, and the vertical rebar cage 11 is connected to the rebar installation.

[0046] Rebars are installed at the top and bottom of the inclined shaft 100 and connected to the vertical steel cage 11, providing connection points for the vertical steel cage 11 and ensuring its stability. Furthermore, the connection method between the rebars and the vertical steel cage 11 enhances the connection strength between the vertical partition 1 and the inclined shaft 100, improving the stability of the vertical partition 1. Among these measures, the vertical steel cage 11 is tied using an operating trolley 2 to accelerate the construction efficiency of tying the vertical steel cage 11.

[0047] Specifically, the rebar installation is carried out using an impact drill. The drill bit diameter should be 4-8 mm larger than the rebar diameter. The rebar diameter is φ16 / φ14, and a φ22 alloy drill bit is used. The drilling depth should be no less than 20d (d is the rebar diameter) and meet the design requirements. The drill bit should always be kept perpendicular to the concrete surface where the rebar is installed.

[0048] In optional implementations, such as Figure 6 , Figure 7 As shown, the operating trolley 10 includes a main frame 101 and an operating platform 102 mounted on the main frame 101, with at least three layers of operating platforms 102 arranged along the height direction of the main frame 101; The bottom of the main frame 101 is provided with a first roller 103.

[0049] The operating trolley 10 is equipped with three operating platforms 102 to meet the operational needs at different heights during the binding of the vertical steel cage 11, thereby improving the convenience of construction. The first roller 103 at the bottom of the main frame 101 facilitates the operation of the operating trolley 10 along the length of the inclined shaft 100, which makes it easier to carry out the binding of the vertical steel cage 11 of the vertical partition 1 section by section, thereby improving the construction efficiency.

[0050] Preferably, the vertical steel cage 11 is installed using an operating trolley 10. There are two operating trolleys 10, each with a three-layer operating platform 102, and edge protection and ladders for workers to go up and down.

[0051] In one or more embodiments, in S2, a formwork trolley 20 is used to pour vertical steel cage 11 in sections. After pouring one section, the formwork trolley 20 moves to the next section for operation.

[0052] The use of a formwork trolley 20 for segmented casting of the vertical steel cage 11 reduces the difficulty of single-span casting and facilitates quality control. After segmented casting is completed, the formwork trolley 20 moves to the next segment, realizing segmented construction and improving construction efficiency.

[0053] Specifically, after the concrete for vertical partition 1 is poured on the first day, the formwork is removed on the second day, and the formwork trolley 20 moves to the next segment. After the formwork is removed, the vertical partition 1 is sprayed with water using a high-pressure water gun and a mist cannon, and geotextile is used to cover and fix it to keep it warm and moist, thus achieving the curing conditions.

[0054] In optional implementations, such as Figure 8 , Figure 9 As shown, the template trolley 20 includes two longitudinally arranged portal frames 201 and two longitudinally arranged first templates 202. One portal frame 201 is connected to a first template 202 on the side close to the other portal frame 201. The two first templates 202 can move closer or further away from each other. The vertical steel cage 11 is located between the two first templates 202. Each portal frame 201 has a second roller 203 at its bottom.

[0055] The portal frame 201 provides stable support for the formwork trolley 20, ensuring stability during the pouring process, and also facilitating the passage of other vehicles or personnel through the cavity of the portal frame 201. Two first templates 202 are set between two portal frames 201. Each first template 202 is installed on its nearest portal frame 201. The first templates 202 can be close to or far from each other, which can adapt to the casting requirements of vertical partitions 1 of different thicknesses. It also facilitates demolding after casting, thus enhancing the versatility of the equipment. Furthermore, the second roller at the bottom of the portal frame 201 allows the template trolley 20 to move smoothly, facilitating the adjustment of the working position within the inclined shaft 100 so as to carry out the pouring operation of the vertical partition 1 section by section.

[0056] In optional implementations, such as Figure 8As shown, it also includes a transverse hydraulic cylinder 204, which is horizontally arranged on the top of the portal frame 201 and is connected to the first template 202.

[0057] The transverse hydraulic cylinder 204 is connected to the first template 202. The transverse hydraulic cylinder 204 drives the first template 202 to move, so that the two first templates 202 move closer or further apart.

[0058] Furthermore, the transverse hydraulic cylinder 204 can provide sufficient support to prevent deformation of the upper part of the template during the pouring process, ensuring the accuracy of the dimensions of the vertical partition plate 1.

[0059] In optional implementations, such as Figure 8 As shown, it also includes a lower mold cylinder 205, one end of which is connected to the side of the portal frame 201, and the other end of which is connected to the lower part of the first template 202.

[0060] The lower mold cylinder 205 connects the portal frame 201 and the lower part of the first template 202, providing reliable support for the lower part of the first template 202 and preventing bulging during casting. Furthermore, the lower mold cylinder 205 adjusts the position of the lower part of the first template 202, ensuring the forming quality of the lower part of the vertical partition 1. In optional implementations, such as Figure 8 As shown, it also includes a top lateral hydraulic cylinder 207. One end of the top lateral hydraulic cylinder 207 is connected to the upper part of the first template 202, and the other end of the top lateral hydraulic cylinder 207 is fixed to the top of the portal frame 201. The position of the upper part of the first template 202 is controlled by the top lateral hydraulic cylinder 207 to ensure the flatness of the top of the first template 202 and to provide effective support for the top of the first template 202. During the concrete pouring process, the support of the top lateral hydraulic cylinder 207 helps to prevent the top of the first template 202 from bulging or deforming.

[0061] In optional implementations, such as Figure 8 As shown, it also includes tie rods 206, which are spaced apart along the height of the first template 202; The tie rod 206 is used to connect the two first templates 202 and fix the two first templates 202 together.

[0062] Specifically, the first template 202 is made of 6mm thick steel plate, through which φ25 tie rods 206 are inserted, with a spacing of 1m between the tie rods 206.

[0063] In an optional embodiment, the first template 202 is provided with vibration holes, wherein the positions of the vibration holes are arranged in a quincunx pattern of 2m×2m.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
