Description

Technical Field

[0001] The utility model relates to a pipe gallery construction trolley, belonging to the technical field of steel mold trolleys in pipe gallery construction. Background Art

[0002] At present, steel formwork trolleys are usually used for construction of underground projects such as pipe corridors and tunnels. According to the operation mode of the steel formwork trolley, the steel formwork trolley is mainly divided into three types: integral type, assembled type and separated type. The common separated steel formwork trolley is separated from top to bottom to solve the design and construction of the hole size change, but the curve change section is also limited. Therefore, in the construction method of underground comprehensive pipe corridors, it is necessary to develop a new split hydraulic trolley for the limited application range of the currently used template trolleys and the difficulty of construction in complex environments.

[0003] In addition, the steel formwork trolley process of the pipe gallery is a construction technology that uses an integral mobile formwork frame to cast in place in sections. Compared with the cast-in-place process of scattered templates, in theory, the trolley process can realize the mechanized disassembly, assembly and overall movement of the template, greatly improve work efficiency, reduce personnel input, and improve the quality of structural molding. In theory, it can realize the high-speed construction of linear structures, which has great development prospects. However, the concrete strength of the traditional integral steel formwork trolley must reach 75% when the formwork is removed, while the concrete strength of the structure with a larger span must reach 100%, and the construction period is long. When used for the construction of large-span cabin structures, either the waiting time for demolding is too long, resulting in low overall work efficiency and difficulty in meeting the progress requirements of long-distance linear structure projects; or more trolleys are required to meet the progress requirements, increasing construction costs; the above two results further lead to the current construction of pipe corridors still mostly using scattered templates for construction. Therefore, it is urgent to design a non-stop rapid construction technology to form a fast flow rhythm, combined with a new split trolley construction technology, to achieve the purpose of significantly improving construction efficiency.

[0004] The patent document with publication number CN108005684A proposes a split steel formwork trolley, including a formwork, a gantry, a traction walking part, a support structure and a hydraulic system. The formwork is located on the peripheral side of the gantry. The formwork includes a top formwork and a side formwork connected to the top formwork. The gantry includes an upper longitudinal beam, a cross beam, a vertical support, two cross beams, a walking beam and a column. A lifting cylinder for bearing the pressure of the side formwork is arranged between the upper longitudinal beam and the cross beam; the formwork and the gantry can be separated into two parts longitudinally, and the gantry is connected at the longitudinal separation by a connecting guard plate and a first connecting piece, and the longitudinal separation of the formwork is connected by a first connecting piece. This solution can simply and quickly realize the separation and splicing of the steel formwork trolley in the longitudinal direction, and to a certain extent solves the problem that the steel formwork trolley is difficult to pass due to its long design in the concrete construction of the curved section of the tunnel. However, the construction method corresponding to this structural scheme can only adopt the traditional overall cast-in-place advancement method in stages, and the construction efficiency is not high.

DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figures 1 to 3 As shown, the utility model includes a middle trolley body and side trolleys, and the side trolleys are arranged on both sides of the middle trolley body. The middle trolley body includes a plurality of middle support frames arranged at intervals along its longitudinal direction, and each group of middle support frames includes an upper crossbeam body 1, a lower crossbeam body 2 and a middle column 3, the upper end of the middle column 3 is fixedly connected to the upper crossbeam body 1, and the lower end of the middle column 3 is fixedly connected to the lower crossbeam body 2; the top of the upper crossbeam body 1 is provided with an intermediate top mold 5 through a top mold template support 4. It can be understood that the lateral direction of the middle trolley body corresponds to the width direction of the pipe gallery, and the longitudinal direction of the middle trolley body corresponds to the length direction of the pipe gallery.

[0035] The side trolley includes a plurality of groups of side support frames arranged at intervals along its longitudinal direction, each group of side support frames includes an upper side end cross beam 6, a lower side end cross beam 7 and a side column 8, the upper end of the side column 8 is connected to the upper side end cross beam 6, and the lower end of the side column 8 is connected to the lower side end cross beam 7; the top of the upper side end cross beam 6 or the side column 8 is provided with a side end top mold 10 through a top mold template support 4; the side of the side column 8 facing away from the middle trolley body is connected to a side mold 12 through a transversely arranged second hydraulic telescopic arm 11, and the second hydraulic telescopic arm 11 is mainly used for supporting and demoulding the side mold 12.

[0036] The two ends of the lower cross beam body 2 are connected to the lower side end cross beam 7 through the first detachable connection structure; the two ends of the upper cross beam body 1 are connected to the upper side end cross beam 6 through the second detachable connection structure; the side end top mold 10 has a first state of being connected to the middle top mold 5 and a second state of being separated. When the middle trolley body and the side trolleys on both sides are fixedly connected to form a whole, the side end top mold 10 and the middle top mold 5 together form the top mold template of the pipe gallery.

[0037] The bottom of the lower cross beam body 2 and the bottom of the lower side end cross beam 7 are respectively provided with hydraulic telescopic lower columns 13, and a walking mechanism 14 is provided at the bottom of the hydraulic telescopic lower columns 13. When the lower cross beam body 2 is separated from the lower side end cross beam 7, and the upper cross beam body 1 is separated from the upper side end cross beam 6 at the same time, the side trolleys on both sides are completely separated from the middle trolley body, and the side trolleys and the middle trolley body can walk independently, and the height of the trolley can be adjusted by using the hydraulic telescopic lower columns 13. The hydraulic telescopic lower columns 13 can also be used for supporting and demoulding the top mold.

[0038] It is understandable that there are various detachable connection structures of the crossbeam, such as end surface connection plates with bolts, connection tongues and grooves with bolts, connection tongues and grooves with latches, etc. In order to make the structure simple, reliable, and easy to disassemble and assemble, the utility model preferably adopts the following scheme: the first detachable connecting structure includes a first L-shaped groove arranged on the upper surface of the lower crossbeam body 2 and a second L-shaped groove arranged on the lower surface of the lower side end crossbeam 7, and the transverse seam surface of the first L-shaped groove and the second L-shaped groove are connected by a vertical tongue 15; the second detachable connecting structure includes a third L-shaped groove arranged on the lower surface of the upper crossbeam body 1 and a fourth L-shaped groove arranged on the upper surface of the upper side end crossbeam 6, and the transverse seam surface of the third L-shaped groove and the fourth L-shaped groove are connected by a vertical tongue 15, and the vertical seam surface of the third L-shaped groove and the fourth L-shaped groove are connected by a transverse tongue 16; the lower end of the side column 8 is connected to the lower side end crossbeam 7 through a vertically arranged first hydraulic telescopic arm 9; the middle part of the upper side end crossbeam 6 is provided with a third hydraulic telescopic arm 17 for adjusting its overall axial length. Among them, the docking of the first L-shaped tongue and the second L-shaped tongue is mainly achieved by the lifting and lowering of the hydraulic telescopic lower column 13, and the docking of the third L-shaped tongue and the fourth L-shaped tongue is achieved by the coordinated cooperation of the first hydraulic telescopic arm 9 and the third hydraulic telescopic arm 17. The reverse design of the upper and lower beam tongues and the tongue pressing design inside the beam effectively improve the safety performance of the equipment. It can be understood that for the connection structure at the third L-shaped tongue and the fourth L-shaped tongue, the coordination design of the vertical tongue 15 and the horizontal tongue 16 should not interfere with the normal operation of the first hydraulic telescopic arm 9 and the third hydraulic telescopic arm 17. For example, at least one of the tongues can be designed as a pluggable structure or in the form of a spring latch.

[0039] To further ensure the reliability of the connection, pressure sensors 18 are respectively provided between the transverse seam surfaces of the first L-shaped groove and the second L-shaped groove, between the transverse seam surfaces of the third L-shaped groove and the fourth L-shaped groove, and between the vertical seam surfaces of the third L-shaped groove and the fourth L-shaped groove. The pressure sensors 18 are mainly used to detect the contact stress at the seam surfaces.

[0040] In order to improve the stability of the side trolley when walking independently, the utility model can adopt the following preferred solution: the side end top mold 10 is fixedly set on the upper side end cross beam 6 through the top mold template support 4, and one end of the upper side end cross beam 6 is rotated relative to the top of the side column 8. The upper side end cross beam 6 has a first state pointing horizontally to the middle trolley body and a second state pointing vertically downward. The first state of the upper side end cross beam 6 corresponds to the state that it can be normally connected to the middle trolley body, see Figure 1 The second state of the upper side end cross beam 6 corresponds to the state of independent walking, see Figure 2 . It can be understood that the upper side end cross beam 6 defined here has a first state and a second state respectively, which means that it can be stably maintained in the first state and the second state. For the rotation adjustment of the upper side end cross beam 6, a conventional electric drive mechanism (such as a rotary motor, a rotary cylinder, a hydraulic gate opener, etc.) can be used, or it can be adjusted manually. For the electric drive mechanism, it generally has a travel locking device, and there is no need to consider the fixing mechanism when the upper side end cross beam 6 is in the first state and the second state. For the manual adjustment method, additional national fixed mechanisms must be considered. The preferred solution adopted by the utility model is that when the upper side end cross beam 6 is in the first state, the side column 8 is connected to the upper side end cross beam 6 through a first diagonal brace 19, and at least one end of the first diagonal brace 19 is provided by a detachable connection structure, and the detachable connection structure here can be of various types, such as bolts, latches, hooks, etc.; when the upper side end cross beam 6 is in the second state, the side column 8 is connected to the upper side end cross beam 6 through a pluggable lock pin.

[0041] To further improve the overall reliability of the device, preferably, when the upper side end cross beam 6 is in the first state, the end of the side end top mold 10 is connected to the upper end of the side mold 12 by a third detachable connecting structure. To facilitate quick disassembly and assembly, the third detachable connecting structure preferably includes a hinge, and one rotating plate of the hinge is connected to the side end top mold 10 by a screw, and the other rotating plate is connected to the side mold 12 by a screw.

[0042] In order to improve the stability of the side trolley when walking independently, the utility model can adopt the following preferred scheme: the side column 8 is connected to the lower side end beam 7 by a second diagonal brace 20, and at least one end of the second diagonal brace 20 is provided with a detachable connection structure. There can also be multiple detachable connection structures here, such as bolts, latches, hooks, etc.

First, excavate the foundation pit, and then carry out the construction of the cushion layer, the tying of the steel bars, the installation of the U-shaped guide wall formwork, and the pouring and curing of the concrete according to the design. The formwork used for the guide wall construction is an integral formwork, which is divided into an inner formwork, an outer formwork, screws connecting the inner and outer forms, and an intermediate support rod.

[0045] Step 2: Installation of side wall and top plate reinforcement. This step can be implemented with reference to the prior art, and the reinforcement binding of the side wall and top plate of the construction section is completed before the template trolley enters.

[0047] Step 4: Support the trolley side molds and top molds in place: According to the design and construction requirements, the hydraulic telescopic lower column 13 and the second hydraulic telescopic arms 11 on both sides are controlled by the hydraulic control system to support the trolley side molds and top molds in place.

[0048] Step 5: Installation of the outer formwork, end formwork and water stop. This step can be implemented with reference to the existing technology. After the trolley formwork is completed, the outer formwork, end formwork and water stop are installed.

[0049] Step 6: Concrete pouring of the first section. This step can be implemented with reference to the prior art. After the steel bars, formwork, water stop and other embedded parts are installed and accepted, the concrete pouring operation is carried out.

[0050] Step seven, the trolley side formwork and the side end top formworks at both ends are shrunk and demoulded: 4 hours after the concrete pouring is completed, the top plate should be sprinkled with water and covered with film for maintenance. After the concrete pouring of the first section is completed and maintained to 50%±2% of the strength requirement, the side formwork 12 can be removed. Remove the outer formwork of the side wall, and at the same time completely separate the upper and lower beams of the trolley, which is equivalent to completely separating the middle trolley body and the side trolley. Finally, the side trolley moves forward relying on the walking mechanism 14 at the bottom. The middle trolley body remains in place, and the early dismantling support system is moved to the original position of the side trolley. The early dismantling support system is connected and fixed to provide auxiliary support for the top formwork. Refer to Figure 4and Figure 5 The early dismantling support system includes support columns 21 with self-adjusting screw rods 22. At least one group of support columns 21 is arranged on both sides of the corridor in the horizontal direction. Each group of support columns 21 is arranged at intervals along the longitudinal direction of the corridor. Support top supports 23 are arranged at the top of the support columns 21. The support top supports 23 located in the same horizontal direction are connected by transverse ribs 24, and the support top supports 23 located in the same longitudinal direction are connected by longitudinal ribs 25.

[0052] Step nine, concrete pouring and curing of the second section: After the entire trolley is locked in place, concrete pouring and curing are carried out.

[0053] Step 10. After the concrete of the second section is poured and cured to 50%±2% of the required strength, the side trolley of the second section is separated from the main body of the middle trolley, and the side trolley is moved forward to the third section; the early-dismantling support system of the first section is dismantled and moved forward to the original position of the side trolley of the second section, and the early-dismantling support system is connected and fixed to provide auxiliary support for the top formwork.

[0054] Step 11: The concrete of the second section is further cured until it meets the conditions for removing the middle top form 5. The middle trolley body is moved forward to the third section. The middle trolley body and the side trolley are fixed as a whole, and then the formwork is put in place.

[0055] Step 12, refer to the above steps 9 to 11, and repeat the construction repeatedly.
