Description

Technical Field

[0001] This application belongs to the field of engineering machinery technology. Specifically, this application provides an intelligent formwork vehicle system for pipe gallery construction and its construction technology. Background Technology

[0002] A utility tunnel, also known as an urban integrated utility tunnel, is an underground tunnel project used to accommodate and lay various municipal pipelines such as electricity, communications, water supply, drainage, gas, and heating. The construction of the main structure of a utility tunnel includes steel reinforcement, formwork systems, and concrete pouring.

[0003] When pouring concrete, the main structure of the utility tunnel requires a formwork system for support. Manually constructing the support frame and formwork is time-consuming and labor-intensive, significantly impacting the construction period and cost. With the development of construction machinery, mechanical methods are gradually replacing manual formwork construction. For example, patent application CN 116517593 A mentions a technology related to a self-propelled hydraulic telescopic formwork trolley for underground utility tunnel construction. When using the formwork trolley, rails are first laid, then the trolley enters the site, relying on mechanical equipment to replace manual labor to form the formwork system.

[0004] While using formwork trolleys can replace manual construction of formwork systems, several drawbacks remain. Formwork trolleys weigh tens of tons, requiring a large initial investment, and incurring high costs for processing, transportation, and installation. Initial installation, commissioning, and acceptance are time-consuming, necessitating specialized drivers and hydraulic technicians, resulting in high training costs and strong personnel dependence. Furthermore, formwork trolleys are designed for fixed cross-sections and cannot be used for cross-section changes, limiting their versatility and application to frame, frame-shear wall, and other engineering structures. Additionally, the complex structure of formwork trolleys makes their hydraulic, transmission, and walking mechanisms prone to interference, potentially causing mechanical damage. Their relocation relies on laid tracks, restricting their movement.

[0005] Therefore, the use of formwork trolleys has limitations and cannot be universally applied to various situations in utility tunnel construction. How to provide a mechanical alternative between formwork trolley construction and manual formwork erection, thereby reducing input costs and shortening the construction cycle during utility tunnel construction, has become a key concern in this field.

The trolley system, wall formwork opening and closing system, and formwork system offer flexible and versatile entry methods. It eliminates the need for dedicated personnel, resulting in lower labor costs. Compared to manual formwork systems, it allows for pre-construction of the formwork and enables automatic movement of the top and wall formwork under the control of an intelligent control system. This system intelligently controls the travel of the top and wall formwork. It significantly saves time and reduces construction costs when working between different sections. Therefore, the intelligent formwork trolley system for utility tunnel construction fills the gap between formwork trolley construction and manual formwork systems, addressing the pain points of high labor costs and long construction periods associated with manual formwork systems when trolleys are unsuitable. In addition, the inclined support telescopic components and inclined support drive components of the intelligent formwork vehicle system for utility tunnel construction are designed to provide support and driving force along the inclined direction. This allows the system to meet the tensile force requirements when the wall formwork detaches from the wall surface with a smaller tensile force, while still meeting the displacement requirements of the wall formwork. This ensures that the intelligent formwork vehicle system for utility tunnel construction meets construction requirements despite its light weight and small driving force.

Detailed Implementation

[0045] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0047] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0048] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0049] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0050] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two groups).

[0051] In the description of the embodiments of this application, the technical terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0054] Based on the above considerations, this application provides an intelligent formwork vehicle system for utility tunnel construction and its construction technology, which is beneficial to shorten the construction cycle and reduce investment costs.

[0055] Please refer to Figures 1 to 7 ,in, Figure 1 This is a schematic diagram of the intelligent formwork vehicle system for utility tunnel construction from one perspective, representing some embodiments of this application. Figure 2 This is a structural schematic diagram of the wall formwork opening and closing system of some embodiments of this application from one perspective; Figure 3 For the purposes of this application Figure 1 Enlarged diagram at point I; Figure 4 For the purposes of this application Figure 1 Enlarged schematic diagram at point II; Figure 5 This is a schematic diagram showing the connection of the top support component in some embodiments of this application; Figure 6 This is a schematic diagram of the structure of an intelligent control system according to some embodiments of this application from one perspective; Figure 7 This is a schematic diagram of the construction process of the utility tunnel according to some embodiments of this application.

[0056] Firstly, such as Figure 1 and Figure 6 As shown, this application provides an intelligent formwork vehicle system for pipe gallery construction, including a frame system 1, a wall formwork opening and closing system 2, a template system 3, and an intelligent control system 4. The frame system 1 includes a frame body 11 and a lifting assembly 12, which is installed on the frame body 11 and used for lifting and lowering on the frame body 11. The wall formwork opening and closing system 2 includes an installation component 21, a diagonal brace telescopic component 22, and a diagonal brace drive component 23. The installation component 21 is connected to the frame body 11, and both the diagonal brace telescopic component 22 and the diagonal brace drive component 23 are connected at one end to the installation component 21 and at the other end to the wall formwork opening and closing system 4. The installation component 21 extends diagonally upwards; the template system 3 includes a top template 31 and a wall template 32. The top template 31 is installed on the lifting component 12, and the wall template 32 is connected to the ends of the diagonal brace extension component 22 and the diagonal brace drive component 23 opposite to the installation component 21. The wall template 32 and the top template 31 are used to enclose the inner side of the pipe gallery for pouring templates; the intelligent control system 4 is connected to the lifting component 12 and the diagonal brace drive component 23 respectively, and is used to control the automatic lifting and lowering of the top template 31 and the automatic opening and closing of the wall template 32.

[0057] In the wall formwork opening and closing system 2, the mounting component 21 is installed on the frame 11, thereby realizing the connection between the wall formwork opening and closing system 2 and the frame 11. The mounting component 21 can be any component that enables the frame 11 to be firmly connected to the diagonal brace telescopic component 22 and the diagonal brace drive component 23. Exemplarily, the mounting component 21 can be permanently fixedly connected to the frame 11 (e.g., by welding, riveting, etc.) or detachably connected to the frame 11 (e.g., by bolt connection, by fasteners, etc.). On the frame 11, the wall formwork opening and closing system 2 can be installed on one side of the frame 11 or on both sides of the frame 11.

[0058] The diagonal expansion joint 22 can extend and retract in its own extension direction, connecting the wall formwork 32 and the mounting component 21, providing support and guidance for the wall formwork 32. The diagonal expansion joint 22 only needs to fulfill its function, and its composition is not limited to rods, pipes, plates, etc. For example, the diagonal expansion joint 22 may include multi-stage sleeved rods that are extendable and retractable in its own length direction; the diagonal expansion joint 22 may also include guiding components and sliding components, with the two components slidingly engaging to achieve the extension and retraction of the diagonal expansion joint 22. The diagonal expansion joint 22 may also be provided with a snap-fit ​​structure to achieve a self-locking function. Multiple diagonal expansion joints 22 can be present at the same height, or multiple can be installed at different heights.

[0059] The driving direction of the diagonal brace drive component 23 is consistent with the extension direction of the diagonal brace telescopic component 22, and both form an angle with the horizontal plane. Specifically, both the diagonal brace drive component 23 and the diagonal brace telescopic component 22 are inclined upwards along the direction away from the frame 11. That is, the angle θ between the axis of the diagonal brace telescopic component 22 and the vertical direction of the frame 11 satisfies the following range: 0° < θ < 90°. For example, the diagonal brace drive component 23 can be a linear motor, a worm gear screw jack, a hydraulic rod, or other components capable of linear drive.

[0060] In the frame system 1, the frame 11 is the main structure, providing support and transportation functions for the lifting assembly 12, the wall formwork opening and closing system 2, and the template system 3. For example, the frame 11 can be a support structure formed by connecting multiple vertical and horizontal members. The vertical members can be fitted with disc buckles, and the horizontal members can be connected to the vertical members (the horizontal members can also be hinged to each other), thereby enabling the frame 11 to be fixed, detachable, and foldable. To facilitate movement of the frame 11, the bottom of the frame 11 can be equipped with casters, electric drive wheels, and a multi-member walking mechanism to achieve movement.

[0061] The lifting assembly 12 is installed on the top of the frame 11 and can drive the top mold template 31 to rise and fall. Exemplarily, the lifting assembly 12 may include a power element and a guide rod. The guide rod is slidably engaged with the frame 11. The power element provides power to drive the top mold template 31 to rise and fall. Multiple locking holes may be provided on the guide rod. By inserting locking pins into the locking holes, the guide rod can be prevented from moving downwards, thus providing support for the top mold template 31. The power element can be a linear motor, a worm gear screw jack, a hydraulic rod, etc. The power element can be the same as the inclined brace drive component 23 to improve interchangeability, or different components can be used to achieve linear drive.

[0062] Both the top formwork 31 and the wall formwork 32 include a keel frame, panels, and connecting fittings. The keel frame forms the framework, the panels are installed on the keel frame, and the connecting fittings connect to the panels and / or the keel frame, providing external connection points. For example, the top formwork 31 can be a flat plate, an arc-shaped plate, or a plate with a recessed center (the recessed center is used for pouring the top beams of the pipe gallery). The wall formwork 32 can be a flat plate, an arc-shaped plate, or a plate with an inclined structure at the top (the inclined structure is used for pouring the chamfered corners of the pipe gallery). The top formwork 31 and / or the wall formwork 32 are not limited to steel formwork, aluminum formwork, plastic formwork, or wooden formwork.

[0063] For example, the frame 11, lifting component 12 and top mold template 31 of this application can be implemented using the above-described scheme. Alternatively, the corresponding structure can be referred to in the patent application document filed by the applicant on January 29, 2026 and published on March 3, 2026, with publication number CN121591139A. These will not be elaborated upon here.

[0064] In the technical solution of this application embodiment, the intelligent formwork vehicle system for utility tunnel construction is lighter and simpler in structure than the formwork trolley, making it easier to move and adjust, and offering advantages in terms of low investment and transportation costs. The frame system 1 and the wall formwork opening and closing system 2 can be assembled as a finished product before entering the site, or they can be assembled as semi-finished products after entering the site. This allows for adaptive adjustment of the top formwork 31 and wall formwork 32 according to the actual construction conditions of the utility tunnel, making it highly versatile. Construction personnel can skillfully operate the lifting and lowering of the top formwork 31 and the opening and closing of the wall formwork 32 after pre-job training, eliminating the need for dedicated personnel and also offering advantages in terms of personnel costs. Compared to manually erected formwork systems, the intelligent formwork vehicle system for utility tunnel construction allows for pre-assembly (i.e., pre-assembly or partial assembly of the intelligent formwork vehicle system before it enters the site) and enables the movement of the top formwork 31 and wall formwork 32. When working between different sections, the entire intelligent formwork vehicle system can be moved simply by moving the top formwork 31 and wall formwork 32. Compared to the complete dismantling and reassembly of manually erected formwork systems, this significantly saves time and reduces construction costs. The lifting assembly 12 and the diagonal brace drive component 23 are both connected to the intelligent control system 4. The intelligent control system 4 accurately controls the stroke of the lifting assembly 12 and the diagonal brace drive component 23, thereby controlling the lifting of the top formwork 31 and the opening and closing of the wall formwork 32. This improves the intelligence of mechanical operation, enhances operational reliability, and reduces operating costs.

[0065] Therefore, the intelligent formwork vehicle system for utility tunnel construction can fill the gap in engineering machinery between formwork trolley construction and manual formwork system construction. In cases where formwork trolleys are not applicable (such as some utility tunnels with complex cross-sections that are inconvenient for formwork trolleys to enter, and some small and medium-sized utility tunnels), it solves the pain points of high labor costs and long construction cycles associated with manual formwork system construction. It is not only suitable for utility tunnel construction, but also applicable to residential projects, factories, underground garages and other projects.

[0066] Furthermore, in the wall formwork opening and closing system 2 of the intelligent formwork vehicle system for utility tunnel construction, the inclined brace telescopic component 22 and the inclined brace drive component 23 are designed to provide support and driving force along the inclined direction, so that the wall formwork 32 moves along the inclined direction (neither parallel to the wall surface of the utility tunnel nor perpendicular to the wall surface of the utility tunnel). It can meet the tensile force requirement when the wall formwork 32 detaches from the wall surface with a small amount of tension while meeting the displacement requirement of the wall formwork 32. Thus, the construction requirements are met under the premise that the intelligent formwork vehicle system for utility tunnel construction is lightweight and has a small driving force.

[0067] like Figure 2As shown, according to some embodiments of this application, optionally, the diagonal brace telescopic member 22 includes a lower diagonal brace 221 and an upper diagonal brace 222. One end of the lower diagonal brace 221 is connected to the mounting member 21, and the other end of the lower diagonal brace 221 is provided with a rotatable support wheel 2211. The lower diagonal brace 221 is provided with a slide rail along its own length direction. One end of the upper diagonal brace 222 is connected to the wall formwork template 32, and the other end of the upper diagonal brace 222 is provided with a rotatable roller 2221. The roller 2221 rolls with the slide rail, and the support wheel 2211 rolls with the upper diagonal brace 222.

[0068] For example, the lower brace 221 can be integrally formed with the mounting part 21, for example, by welding; the lower brace 221 can also be detachably connected to the mounting part 21, for example, by snap-fit ​​or bolt connection.

[0069] For example, the lower inclined support 221 can be a tube, such as a square tube; the support wheel 2211 can be a bearing mounted on the lower inclined support 221; and the roller 2221 can be a pulley mounted on the upper inclined support 222.

[0070] For example, the upper inclined support 222 can be sleeved with the lower inclined support 221. For example, the upper inclined support 222 extends outward from the lower inclined support 221 or retracts into the lower inclined support 221. The upper inclined support 222 can also be located parallel to the axis of the lower inclined support 221. That is, the part where the upper inclined support 222 connects with the lower inclined support 221 can be located above the lower inclined support 221 or below the lower inclined support 221 (in this case, the roller 2221 needs to be set inside the lower inclined support 221, or the lower inclined support 221 is equipped with a support member to bear the weight of the wall formwork template 32 and the upper inclined support 222).

[0071] In the technical solution of this application embodiment, the lower inclined support 221 is in rolling engagement with the upper inclined support 222 through the support wheel 2211, and the upper inclined support 222 is in rolling engagement with the lower inclined support 221 through the roller 2221. Firstly, the sliding friction is changed to rolling friction, which can reduce the resistance when the upper inclined support 222 moves; secondly, the support wheel 2211 can provide a limit for the roller 2221, preventing the upper inclined support 222 from slipping off and improving reliability.

[0072] like Figure 2 As shown, according to some embodiments of this application, optionally, the diagonal brace telescopic member 22 further includes a guide member 223. The guide members 223 are arranged in pairs, connected to both sides of the lower diagonal brace member 221, and located at the end of the lower diagonal brace member 221 away from the mounting member 21, for providing sliding guidance for the upper diagonal brace member 222.

[0073] For example, the guide member 223 can be a plate installed on the lower inclined support member 221, or it can be a pipe installed on the lower inclined support member 221. Preferably, the guide member 223 is a square tube welded to the lower inclined support member 221, which is convenient to obtain materials and has high structural strength.

[0074] In the technical solution of this application embodiment, the lower inclined support 221 is equipped with a pair of guide members 223 at the end away from the mounting member 21. This not only regulates the displacement of the upper inclined support 222 and provides guidance for the upper inclined support 222, but also provides support on the side of the upper inclined support 222 to prevent the upper inclined support 222 from swaying to the side.

[0075] like Figure 2 As shown, according to some embodiments of this application, optionally, the diagonal brace telescopic member 22 further includes a diagonal brace limiting member 224, which is detachably installed on the upper diagonal brace member 222 and is used to abut against the lower diagonal brace member 221 to limit the downward movement of the upper diagonal brace member 222.

[0076] For example, the upper diagonal brace 222 may have multiple mounting holes along its length to mark different extension lengths of the upper diagonal brace 222. The diagonal brace limiting member 224 may be installed on different mounting holes of the upper diagonal brace 222 to abut against the lower diagonal brace 221.

[0077] For example, the mounting hole can be a threaded hole; the diagonal brace limiting member 224 can be provided with a through hole and a bolt, and the bolt passes through the through hole and is threadedly connected to the mounting hole to fix the diagonal brace limiting member 224 on the upper diagonal brace member 222. Furthermore, the diagonal brace limiting member 224 can also be provided with multiple through holes, one to improve the connection strength and the other to reduce the adjustment distance.

[0078] For example, the diagonal brace limiting member 224 can be any of the following: square tube, metal block, polymer material block, etc., or any combination thereof (e.g., a polymer material block is provided at the end of the metal block to reduce rigid contact, a metal block or metal plate is provided at the end of the square tube to improve structural strength, etc.).

[0079] In the technical solution of this application embodiment, the diagonal brace telescopic member 22 provides support for the wall formwork template 32. When in use, it bears pressure along the extension direction. The diagonal brace limiting member 224 provides displacement restriction for the upper diagonal brace member 222, which not only facilitates adjustment, but also meets the connection strength requirements under pressure.

[0080] like Figure 2As shown, according to some embodiments of this application, optionally, along the extending direction of the diagonal brace telescopic member 22, the slide is located on the upper surface of the inner cavity of the lower diagonal brace member 221, the top of the support wheel 2211 is higher than the upper surface of the lower diagonal brace member 221, the top of the roller 2221 is lower than the lower surface of the upper diagonal brace member 222, the roller 2221 is located in the inner cavity of the lower diagonal brace member 221, and the outer diameter of the roller 2221 is smaller than the cross-sectional depth of the inner cavity of the lower diagonal brace member 221.

[0081] For example, the lower inclined support 221 is a square tube with a groove at its top. The groove width is less than the axial width of the roller 2221, and the top surface of the inner cavity of the square tube is a slide.

[0082] In the technical solution of this application embodiment, at the connection between the upper inclined support 222 and the lower inclined support 221, the upper inclined support 222 is located above the lower inclined support 221. The roller 2221 of the upper inclined support 222 rolls and rubs against the upper surface of the inner cavity of the lower inclined support 221, and the support wheel 2211 of the lower inclined support 221 rolls and rubs against the bottom surface of the upper inclined support 222. By setting the stress-bearing parts at the upper part of the lower inclined support 221 and the lower part of the upper inclined support 222, not only can the cross-sectional blunting of the lower inclined support 221 be reduced, but fatigue deformation on the lower inclined support 221 can also be detected in time, reducing the potential failure risk.

[0083] like Figure 2 As shown, according to some embodiments of this application, optionally, there are multiple rollers 2221, and the multiple rollers 2221 are spaced apart along the extension direction of the upper inclined support 222.

[0084] For example, along the extending direction of the upper inclined support 222, the roller 2221 can be in one column and multiple rows, or in multiple columns and multiple rows. Preferably, the roller 2221 is arranged in one column and multiple rows, with each row spaced apart (spaced apart along the extending direction of the upper inclined support 222).

[0085] In the technical solution of this application embodiment, the upper inclined support 222 forms a roller 2221 group by setting multiple rollers 2221, which can disperse the compressive stress on the lower inclined support 221, thereby avoiding stress concentration and improving the service life of the lower inclined support 221.

[0086] like Figure 2As shown, according to some embodiments of this application, optionally, the diagonal brace drive member 23 includes a linear drive element 231 and a diagonal brace transmission member 232. The linear drive element 231 is connected to the mounting member 21. The diagonal brace transmission member 232 includes a first transmission member 2321 and a second transmission member 2322. The first transmission member 2321 and the second transmission member 2322 are sleeved together. The first transmission member 2321 is provided with a strip-shaped hole along the extension direction. The second transmission member 2322 is provided with a through hole. A connector is inserted into the strip-shaped hole and the through hole. One end of the first transmission member 2321 is connected to the wall formwork template 32. The second transmission member 2322 is connected to the linear drive element 231.

[0087] When the diagonal brace drive member 23 drives the wall formwork template 32 to move outward (and upward), the plug-in member abuts against the end of the strip hole near the wall formwork template 32. After the template system is formed, the wall formwork template 32 is located in the predetermined position. At this time, the diagonal brace telescopic member 22 plays a supporting role and can control the separation of the plug-in member from the end of the strip hole.

[0088] For example, the linear drive element 231 is a worm gear screw jack, and the inclined support transmission element 232 is provided with a transmission nut that drives the worm gear screw jack. The worm gear screw jack is mounted on the mounting part 21 by bolt connection, and the transmission nut is welded to the second transmission element 2322.

[0089] For example, the first transmission component 2321 is sleeved on the outside of the second transmission component 2322, and the second transmission component 2322 is sleeved on the outside of part of the screw of the worm gear screw jack. Both the first transmission component 2321 and the second transmission component 2322 are square tubes.

[0090] For example, the diagonal brace drive member 23 can be detachably connected to the mounting member 21 by means of bolt connection, which is convenient for disassembly and assembly; the diagonal brace drive member 23 is hinged to the wall formwork template 32, which can reduce or even eliminate the torque between the diagonal brace drive member 23 and the wall formwork template 32.

[0091] For example, the connector can be a bolt and a nut, with the bolt inserted into a slotted hole and a through hole, and the nut connected to the end of the bolt away from the head.

[0092] In the technical solution of this application embodiment, the strip hole of the first transmission member 2321 and the through hole of the second transmission member 2322 are connected by a plug-in member. After the template system is formed, the plug-in member is located between the two ends of the strip hole. At this time, a buffer distance can be provided for the linear drive element 231 to avoid the linear drive element 231 being subjected to the force from the wall formwork template 32, thereby effectively protecting the linear drive element 231.

[0093] like Figure 1As shown, according to some embodiments of this application, optionally, there are multiple diagonal bracing telescopic members 22 and multiple diagonal bracing driving members 23, and the multiple diagonal bracing telescopic members 22 and multiple diagonal bracing driving members 23 are arranged in parallel; the multiple diagonal bracing telescopic members 22 and multiple diagonal bracing driving members 23 are distributed in a rectangular array, and in the height direction and at the same height, the diagonal bracing telescopic member 22 is located between two diagonal bracing driving members 23, and / or the diagonal bracing driving member 23 is located between two diagonal bracing telescopic members 22.

[0094] At the same height, the diagonal brace telescopic component 22 and the diagonal brace drive component 23 are staggered; in the height direction, the diagonal brace telescopic component 22 and the diagonal brace drive component 23 are staggered.

[0095] For example, the rectangular array formed by multiple diagonal bracing telescopic members 22 and multiple diagonal bracing drive members 23, with the same height as the rows and the height direction as the columns, is at least two rows and three columns.

[0096] In the technical solution of this application embodiment, multiple diagonal bracing telescopic members 22 and multiple diagonal bracing driving members 23 are distributed in a rectangular array, which can optimize the force distribution, make the wall formwork 32 bear the force evenly, and reduce the lateral force on the diagonal bracing telescopic members 22 and the diagonal bracing driving members 23. Furthermore, in the height direction and at the same height, the diagonal bracing telescopic members 22 and the diagonal bracing driving members 23 are staggered, which can distribute multiple diagonal bracing driving members 23 around the diagonal bracing telescopic members 22, so that the diagonal bracing telescopic members 22 bear the force evenly, and avoid the diagonal bracing telescopic members 22 from being blocked due to unilateral force, thereby improving the smoothness of the operation of the wall formwork opening and closing system 2.

[0097] like Figure 1 As shown, according to some embodiments of this application, optionally, the angle between the diagonal brace telescopic member 22 and the height direction of the frame 11 is in the range of 30° to 60°.

[0098] For example, the angle θ between the diagonal brace extension member 22 (or diagonal brace drive member 23) and the height direction of the frame 11 can be any value among 30°, 32°, 34°, 36°, 38°, 40°, 42°, 44°, 46°, 48°, 50°, 52°, 54°, 56°, 58°, and 60°, or any intermediate value between any two of the aforementioned values.

[0099] In the technical solution of this application embodiment, the angle between the diagonal bracing telescopic member 22 (or diagonal bracing driving member 23) and the height direction of the frame 11 is designed to be between 30° and 60°, which can take into account both the stroke requirements of the wall formwork template 32 and the force requirements of the diagonal bracing driving member 23.

[0100] Furthermore, the angle between the diagonal brace expansion member 22 and the height direction of the frame 11 is 45°. When the wall formwork 32 detaches from the pipe gallery wall, the diagonal brace drive member 23 pulls the wall formwork 32 along the 45° direction, achieving optimal tension and stroke. At the 45° angle, both the smoothness of the diagonal brace expansion member 22 and the load-bearing requirements of the diagonal brace expansion member 22 are improved, thus reducing friction and preventing the wall formwork 32 from falling off (preventing the wall formwork 32 from being unable to be pulled down).

[0101] like Figure 2 As shown, according to some embodiments of this application, optionally, the mounting part 21 includes a mounting part 211 and a reinforcing part 212. The mounting part 211 is detachably connected to the frame 11, and the reinforcing part 212 is connected to the mounting part 211 and at least a pair of guides 223 located at the top of the rectangular array.

[0102] For example, the mounting part 211 can be a longitudinal bar arranged along the height direction of the frame 11, and the reinforcing part 212 can be a horizontal bar arranged perpendicular to the mounting part 211 (in other embodiments, the reinforcing part 212 and the mounting part 211 can be arranged at an acute angle). The mounting part 211 and the reinforcing part 212 can be integrally formed by welding, or they can be detached by bolting. The mounting part 211 and the frame 11 are preferably detachably connected by a disc buckle and a lock, and the reinforcing part 212 and the guide member 223 are preferably connected by bolts.

[0103] In the technical solution of this application embodiment, the mounting component 21 is detachably connected to the frame 11, which enables the rapid disassembly and assembly of the frame system 1 and the wall formwork opening and closing system 2, thereby improving construction efficiency. Furthermore, the diagonal brace drive component 23 and the diagonal brace telescopic component 22 are both mounted on the mounting component 21 (instead of being connected to the frame 11 separately), which can improve the structural strength of the wall formwork opening and closing system 2 and improve the installation accuracy of the diagonal brace drive component 23 and the diagonal brace telescopic component 22. In addition, the guide component 223 not only plays a guiding role but also provides a connection position for the reinforcing part 212, connecting the lower diagonal brace component 221, the reinforcing part 212, and the mounting part 211 into a triangular stable structure, further improving structural stability.

[0104] like Figure 2 As shown, according to some embodiments of this application, optionally, the diagonal brace expansion member 22 is detachably connected to the mounting part 211, and the diagonal brace expansion member 22 is hingedly connected to the wall formwork template 32.

[0105] For example, the diagonal brace expansion member 22 is bolted to achieve a detachable connection with the mounting part 211.

[0106] In the technical solution of this application embodiment, the diagonal brace expansion member 22 is flexibly connected to the mounting part 211, which is convenient for disassembly and assembly; the diagonal brace expansion member 22 is hinged to the wall formwork template 32, which can reduce the local stress at the connection and make the connection only subject to the axial force of the diagonal brace expansion member 22.

[0107] like Figure 6 As shown, according to some embodiments of this application, optionally, the intelligent control system 4 includes a gate box 41, a control circuit module 42, and a timing module 43. The gate box 41 is provided with an external interface 411, which is used to connect to the lifting assembly 12 and the inclined support drive 23. The control circuit module 42 and the timing module 43 are both installed inside the gate box 41. The control circuit module 42 is connected to the external interface 411, and the timing module 43 is connected to the control circuit module 42. The timing module 43 is used to provide the control circuit module 42 with stroke control for the lifting assembly 12 and the inclined support drive 23.

[0108] In the intelligent control system 4, the lifting assembly 12 and the inclined support drive component 23 are connected to the external interface 411 on the gate box 41, thereby realizing intelligent control of the lifting assembly 12 and the inclined support drive component 23. When multiple intelligent formwork vehicle systems for pipe gallery construction need to work together, multiple lifting assemblies 12 and multiple inclined support drive components 23 are connected in parallel to the external interface 411 on the gate box 41, which can also realize the synchronous operation of multiple lifting assemblies 12 and multiple inclined support drive components 23 controlled by one intelligent control system 4. Specifically, the control circuit module 42 is used to control the lifting assembly 12 and the inclined support drive component 23, and the timing module 43 is used for timing. When the intelligent control system 4 is running, after setting the time, the control circuit module 42 can control the operation of the lifting assembly 12 and the inclined support drive component 23, and the timing module 43 measures the running time of the lifting assembly 12 and the inclined support drive component 23, thereby enabling the control circuit module 42 to intelligently control the stroke of the top formwork template 31 and the wall formwork template 32 according to the time.

[0109] It is worth emphasizing that when controlling the operation of the lifting assembly 12 and the inclined support drive 23, it is crucial that the top formwork 31 and the wall formwork 32 have reached their predetermined positions. Typically, position sensors are used to obtain position signals; for example, a linear position sensor can be used to obtain position feedback signals. However, this application does not employ a control scheme using position sensors.

[0110] In the technical solution of this application embodiment, the timing operation time is used as the control scheme, which has advantages over the position sensor feedback control scheme. First, it reduces the installation of sensors in the working environment, optimizes the structural layout, and avoids sensor failure due to harsh working conditions, thereby improving operational reliability. Second, it reduces costs and the number of parts (sensors need to be installed one by one, while only one timing module 43 needs to be installed), which is conducive to the transformation of intellectual property and product production.

[0111] like Figure 6 As shown, according to some embodiments of this application, optionally, the intelligent control system 4 further includes a remote control receiving module 44 and a remote controller. The remote control receiving module 44 is connected to the control circuit module 42, and the remote controller is signal-connected to the remote control receiving module 44.

[0112] The remote control receiver module 44 is installed inside the gate box 41 to receive signals from the remote control. The operator holds the remote control in his hand and can remotely (away from the working area of ​​the intelligent formwork vehicle system for pipe gallery construction) control the lifting and lowering of the top formwork 31 and the opening and closing of the wall formwork 32.

[0113] In the technical solution of this application embodiment, the intelligent control system 4 can realize remote one-button control through the remote control receiving module 44 and the remote controller, thereby avoiding the risk of accidental injury to personnel and improving the level of intelligence and safety.

[0114] Furthermore, the intelligent control system 4 also includes a residual current device (RCD), an overload protector, and a socket, which are connected to the control circuit module 42. The RCD provides leakage protection; the overload protector provides overload protection; and the socket can be connected to an external power source to power the intelligent formwork vehicle system for pipe gallery construction.

[0115] like Figure 6 As shown, according to some embodiments of this application, optionally, the external interface 411 includes a first interface 4111 and a second interface 4112. The first interface 4111 is used to connect with the lifting assembly 12, and the second interface 4112 is used to connect with the inclined support drive member 23. The first interface 4111 and / or the second interface 4112 are provided with a label layer and / or a foolproof stop.

[0116] When the intelligent formwork vehicle system for utility tunnel construction is in operation, multiple intelligent formwork vehicle systems often need to be used in coordination. In this case, the wiring of multiple lifting components 12 can be connected in parallel via cables to form a connector, which is inserted into the first interface 4111; the wiring of multiple diagonal brace drive components 23 can also be connected in parallel via cables to form a connector, which is inserted into the second interface 4112. The intelligent control system 4 controls the synchronous displacement of all top formwork blocks and all wall formwork 32, achieving one-button control.

[0117] For example, the outer surface of the first interface 4111 can be set to red, and the outer surface of the second interface 4112 can be set to blue. Using different colors as a marking layer reminds the operator to insert the connector into the corresponding interface.

[0118] For example, a stop can be provided on the first interface 4111 to allow the connector of the lifting assembly 12 to be inserted while blocking the connector of the inclined brace drive member 23 from being inserted; the stop can also be provided on the second interface 4112; or the first interface 4111 and the second interface 4112 can both be provided with stop blocks of different shapes; even, the stop can be formed on the outer contour of the first interface 4111 and / or the second interface 4112, so that the sizes of the first interface 4111 and the second interface 4112 are different.

[0119] In the technical solution of this application embodiment, the external interface 411 forms only two interfaces: one for connecting the external lifting component 12 and the other for connecting the external inclined support drive component 23, which simplifies the connection and facilitates operation. Furthermore, the first interface 4111 and the second interface 4112 are designed to prevent operator error.

[0120] like Figure 4 As shown, according to some embodiments of this application, optionally, the wall formwork template 32 is provided with a plurality of hinge members 324. The hinge member 324 includes a hinge part 3241 and a pair of horizontal parts 3242. The plurality of hinge parts 3241 are hinged to the diagonal brace telescopic member 22 and the diagonal brace drive member 23 respectively. The horizontal parts 3242 are connected to the hinge parts 3241. The main keel of the wall formwork template 32 is connected between two horizontal parts 3242 that are spaced apart vertically. The horizontal parts 3242 are provided with insertion holes for inserting pins to fix the main keel.

[0121] The number of hinges 324 is equal to the total number of diagonal brace telescopic members 22 and diagonal brace drive members 23, and they are connected one-to-one. Each hinge 324 includes a hinge part 3241 and two horizontal parts 3242. The two horizontal parts 3242 are attached to the main keel above and below the main keel, respectively. The pin passes through the insertion hole of the horizontal part 3242 (multiple elongated holes are provided on the main keel, and the pin passes through the elongated holes) to realize the detachable connection between the hinge 324 and the main keel of the wall formwork template 32.

[0122] In the technical solution of this application embodiment, the wall formwork template 32 is detachably connected to the main keel through the hinge 324. When the pin is inserted and fixed, it is inserted along the height direction, which can avoid affecting the working surface of the wall formwork template 32.

[0123] like Figure 3As shown, according to some embodiments of this application, optionally, the template system 3 further includes a joint template 33, which is connected between the wall template 32 and the top template 31; the top template 31 is provided with a first support member 311 at one end facing the wall template 32, and the wall template 32 is provided with a second support member 323 at one end facing the top template 31, with the top surface of the first support member 311 and the top surface of the second support member 323 respectively supporting the two ends of the joint template 33.

[0124] When dealing with pipe racks of different widths, if there is a gap between the wall formwork 32 and the top formwork 31, it can be filled by the joint formwork 33, so that the joint formwork 33 can work together with the wall formwork 32 and the top formwork 31 to adapt to different pipe rack widths.

[0125] For example, both the first support member 311 and the second support member 323 can be angle steel. Furthermore, in order to improve the structural strength of the first support member 311 and the second support member 323, ribs can also be provided on the angle steel, that is, multiple ribs can be provided at intervals along the length of the angle steel.

[0126] For example, the top surface of the first support member 311 is coplanar with the top surface of the second support member 323; the top surface of the first support member 311 is lower than the top surface of the top mold template 31, and the height difference between the two is in the range of 10mm to 20mm, for example, it can be any value among 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, and 20mm, or any intermediate value between any two of the above values, so as to reserve a position for the splicing template 33, so that the splicing template 33 is coplanar with the top surface template.

[0127] In related technologies, the joint panels that serve to fill the gaps are nailed together piece by piece, and then need to be chiseled off piece by piece later, which is difficult to operate and requires a lot of work.

[0128] In the technical solution of this application embodiment, the first support 311 and the second support 323 can work together to support the joint template 33, thereby filling the gap between the wall template 32 and the top template 31, so as to adapt to the cross-section of different widths of the pipe gallery, avoid grout leakage, and reduce the workload of disassembling and assembling the joint template 33.

[0129] like Figure 1 As shown, according to some embodiments of this application, optionally, the wall formwork template 32 includes an integrated wall formwork 321 and a corner formwork 322, the bottom of the corner formwork 322 is detachably connected to the top of the integrated wall formwork 321, and a second support member 323 is disposed on the corner formwork 322.

[0130] For example, the top of the integrated wall mold 321 and the bottom of the corner mold 322 can be detachably connected by bolts.

[0131] In the technical solution of this application embodiment, the wall formwork template 32 includes an integrated wall formwork 321 and a corner formwork 322 that is detachably installed on the integrated wall formwork 321. The corner formwork 322 can be replaced according to different corner requirements of the pipe gallery, thereby expanding the applicability, reducing template idleness and improving turnover rate.

[0132] like Figure 1 As shown, according to some embodiments of this application, optionally, the frame system 1 further includes an extension support member 13, which is connected to the top end of the lifting assembly 12, and is connected to the top mold template 31 below the top mold template 31. The end of the extension support member 13 extends to the bottom of the second support member 323, and the extension support member 13 is used to provide support for the wall mold template 32, the joint template 33, and the top mold template 31.

[0133] For example, the extended support member 13 can be a plate, a pipe, or a frame formed by welding pipes. In the width direction of the pipe gallery, the size of the extended support member 13 is larger than the size of the top formwork 31.

[0134] In the technical solution of this application embodiment, the extended support member 13 extends to the bottom of the second support member 323, which can simultaneously provide support for the corner mold 322, the joint template 33 and the top mold template 31, thereby improving the structural strength and the surface quality after casting.

[0135] like Figure 5 As shown, according to some embodiments of this application, optionally, the frame system 1 further includes a top support assembly 14, which replaces the extension carrier 13 in supporting the joint template 33. Specifically, the top support assembly 14 includes a top carrier 141 and a top support 142. The top carrier 141 is connected to the lifting assembly 12, and the top support 142 is connected to the top carrier 141. The top support 142 is located below the first support 311 and the second support 323. The top support 142 is used to provide support for the wall template 32, the joint template 33, and the top template 31.

[0136] For example, the top support member 141 can be a connection structure formed by one or more rods to support the top support member 142; the top support member 142 can be a rod, plate, etc., and is supported between the top formwork template 31, the joint template 33 and the wall formwork template 32 (corner template 322).

[0137] In the technical solution of this application embodiment, the top support component 14 is connected to the lifting component 12 through the top bearing component 141 and can rise and fall synchronously with the lifting component 12; the top support component 14 is supported under the top formwork template 31, the joint template 33 and the wall formwork template 32, which can improve the structural strength of the connection and provide a reference for the first support component 311 and the second support component 323, avoid warping, and make the top surfaces of the top formwork template 31, the joint template 33 and the wall formwork template 32 coplanar.

[0138] like Figure 5 As shown, according to some embodiments of this application, optionally, the top support member 141 includes a first support member, a second support member, and a third support member.

The second and third support members are connected at one end to the lifting assembly 12 and at the other end to the first support member. The second support member is arranged parallel to the top support member 142. The third support member is located below the second support member and gradually extends from the lifting assembly 12 to the first support member towards the second support member.

[0139] For example, the second carrier and the lifting assembly 12 are detachably connected by a lock and a buckle, and the end of the third carrier is provided with a channel steel that abuts against the lifting assembly 12.

[0140] For example, the top support 142 is a square tube, the first support member is a square tube, the third support member is a square tube, and the second support member is a round tube.

[0141] In the technical solution of this application embodiment, the second bearing member is arranged parallel to the top support member 142, which makes it easy to find the reference of the top support assembly 14; the third bearing member is arranged at an angle to the second bearing member, so that the third bearing member is only subjected to pressure along the extension direction, which can improve the support capacity and reduce bending deformation.
