Description

Technical Field

[0001] The invention relates to the technical field of track segments, and in particular to a track concrete high-strength segment structure and processing equipment thereof. Background Art

[0002] In modern urban transportation, as ground space planning has become increasingly perfect, how to use underground space to improve the carrying capacity of the transportation system is an important development direction. The planning of urban subway tunnels has greatly alleviated the traffic pressure in the city. The construction process of underground tunnels is mainly shield construction. During the shield construction process, the tunnel behind the shield needs to be supported and installed by segments. At this stage, the tunnel segments are mainly made of concrete materials. In order to increase the support, steel bars are often embedded inside the tunnel segments.

[0003] The current production of tunnel segments mainly goes through the following production processes: first, suitable concrete needs to be selected, mixed and tested for concrete performance, and then suitable steel cages need to be made according to the shape of the segment, and then concrete is poured through molds. After pouring, demolding and maintenance are carried out. From the above process, the structural strength of the tunnel segment is mainly reflected in the high hardness, high bearing capacity and high toughness imparted by high-strength concrete and steel skeleton.

[0004] At present, the structural strength of the main body of the tunnel segment can be guaranteed by high-strength concrete and steel mesh, but the current segment connection positions are often connected by pre-embedded rods supplemented by sockets, mortise and tenon joints, etc. However, this connection method has a small force surface at the socket position and the connection point is easily affected by problems such as water seepage, resulting in a reduction in the overall structural strength of the pipe ring formed by the tunnel segment.

[0005] In the current production process of tunnel segments, the steel skeleton often needs to be welded. Firstly, the welding connection method has too many connection points, and the structural strength of each welding point needs to be fully verified, which takes a long construction period. Secondly, the welding connection method has poor structural integrity, and the connection position of the welding point is prone to stress cracking, which affects the overall structural strength of the segment.

[0006] Moreover, in the current production process of tunnel segments, molds are mainly used to cast tunnel segments. However, in order to avoid bubbles mixed into the concrete and uneven distribution of materials during casting, vibration is required during casting. However, the current vibration is mainly performed manually using a vibrator. However, manual vibration is labor-intensive and long-term labor affects the health of workers. Secondly, since manual operation is not precise, it brings about the problem of uneven distribution of the vibration effect, which easily leads to insufficient discharge of local bubbles. Furthermore, the current processing equipment still has the problem of low processing efficiency. Not only does the vibration require manual assistance, but the scraping is also performed manually, so the efficiency is low. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was created. Summary of the invention

The steel main structure is simple to produce and welded quickly, which effectively reduces the welding workload, improves the production efficiency of the pipe segment, and ensures the integration and structural strength of the pipe segment. It also has the following specific advantages;

[0038] 1. The steel frame uses a pair of parallel arc-shaped positioning plates to form the upper and lower welding bodies of the steel frame. When used, the steel frame is formed by adding transverse ribs, reinforcement components and reinforcement ribs to improve the overall structural strength of the steel frame. A pair of positioning plates can be integrally formed, which not only reduces the workload during welding, but also makes the integrally formed structure stronger;

[0039] 2. Matching connection components are set on both sides of the steel frame. The connection components are composed of side reinforcement ribs and connecting side plates.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] See also Figure 1-12The present invention provides an implementation scheme: in the application process of track concrete segments, the segments are mainly processed by casting, and the structural strength of the segments is improved by cooperating with steel skeletons. However, the current track concrete segments have the following problems: first, the transverse connection structure of the segments is mainly connected by socket or riveting, and the connection of the segments is not sufficient, which easily leads to insufficient structural strength of the segment track; second, the steel skeleton of the segments has many welding points, and auxiliary equipment is required for alignment and fixation, which is inconvenient to operate; third, manual auxiliary vibration is required during casting, and since the range of vibration is limited and the vibration rate is low, the operation is inconvenient and bubbles are easily retained, and manual scraping is required, and the low production efficiency affects the quality of the segments.

[0058] Embodiment 1: According to the specification sheet Figure 1 -Attached Figure 6 It can be seen that in response to the above problems, the present application discloses a rail concrete high-strength segment structure, including a concrete segment body 1 and a steel frame 2, the steel frame 2 serving as the skeleton of the concrete segment body 1, the concrete segment body 1 being a main structure cast by concrete, the concrete segment body 1 being wrapped outside the steel frame 2, the concrete segment body 1 being an arc-deficient annular plate of a concrete structure, and multiple concrete segment bodies 1 being enclosed to form a tube-shaped body when in use, mutually matching connecting components 27 being arranged on both sides of the concrete segment body 1, and the connecting components 27 can play a role in radial connection of adjacent concrete segment bodies 1, and then the steel frame 2 is an arched frame, the arched structure of the steel frame 2 matches the shape of the concrete segment body 1, and plays a role in strengthening the concrete segment body 1, the concrete segment body 1 is cast and wrapped outside the steel frame 2, the compressive strength of the concrete used for the concrete segment body 1 is at least 30MPa, the concrete waterproof grade of the concrete segment body 1 is not less than the anti-seepage grade of P10, and the concrete and steel selection of the concrete segment body 1 need to meet the strength and waterproof requirements;

[0059] Furthermore, according to the instructions attached Figure 1 -Attached Figure 6 It can be seen that the steel frame 2 includes a pair of symmetrical positioning plates 21, the pair of positioning plates 21 are arranged opposite to each other, one positioning plate 21 is provided with four positioning sleeves 22, and the other positioning plate 21 is provided with four positioning rods 23, and the positioning rods 23 are assembled in the positioning sleeves 22;

[0060] In the specific implementation process, the four positioning sleeves 22 on one positioning plate 21 correspond to the four positioning rods 23 on another positioning plate 21. When welding, the positioning plate 21 provided with the positioning rods 23 is first matched with the positioning sleeves 22 on the other positioning plate 21, so that the positioning rods 23 are inserted into the positioning sleeves 22, and then the pair of positioning plates 21 are fixed, which is convenient for welding the steel frame 2 and improves the convenience of welding;

[0061] Furthermore, a pair of positioning plates 21 is a pair of arc-shaped plates, and the curvatures of the pair of positioning plates 21 match each other. The pair of positioning plates 21 are arranged relative to each other to form a pair of steel bar structure bodies on the radial outer side and inner side of the pipe segment of the steel frame 2. A plurality of pairs of transverse ribs 24 are welded on opposite sides of the pair of positioning plates 21 to strengthen the structure of the positioning plates 21. The plurality of pairs of transverse ribs 24 are evenly distributed on the positioning plates 21 in a fan shape and are welded to the positioning plates 21. A plurality of casting channels 29 are provided at intervals corresponding to the plurality of transverse ribs 24 on the positioning plates 21. The casting channels 29 are used for passing through during the casting and forming process of the concrete pipe segment body 1, and reduce the structural weight of the positioning plates 21, so that the steel frame 2 and the pipe segment are more fully combined. Moreover, the positioning plates 21 are an integrated structure, which is convenient for manufacturing during production.

[0062] The reinforcement between the pair of positioning plates 21 cannot effectively play a supporting role only by the cooperation of the positioning sleeve 22 and the positioning rod 23, and the degree of integration with the concrete pipe segment body 1 is insufficient. Therefore, a plurality of reinforcing ribs 25 are arranged between the pair of positioning plates 21 in a matrix, and the two ends of the plurality of reinforcing ribs 25 are welded to the plurality of transverse ribs 24 of the pair of positioning plates 21;

[0063] Furthermore, a plurality of reinforcing components 26 are evenly arranged along the axial direction on the transverse rib 24, and the ends of the reinforcing components 26 are connected to the ends of the reinforcing ribs 25. The reinforcing components 26 are welded to the positioning plate 21 and the ends of the reinforcing ribs 25 to improve the connection effect between the reinforcing ribs 25 and the positioning plate 21, and the reinforcing components 26 also play a role in radially reinforcing the positioning plate 21.

[0064] According to the instruction manual Figure 1 -Attached Figure 6 It can be seen that the connection assembly 27 includes a socket wing 11, one side of the concrete segment body 1 extends out of the socket wing 11, the other side of the concrete segment body 1 is recessed with a socket 12, the structure of the socket wing 11 matches the socket 12, and the socket wing 11 is provided with a side reinforcing rib 271 which is welded to one side of the positioning plate 21;

[0065] In the specific implementation process, the cross section of the socket side wing 11 is a trapezoidal structure, the cross section of the side reinforcement rib 271 is a trapezoidal cavity structure, one end of the side reinforcement rib 271 is welded to the side of a pair of positioning plates 21, so that the side reinforcement rib 271 is connected to the positioning plate 21, and the socket side wing 11 is strengthened by the side reinforcement rib 271, thereby improving the integrity and bonding of the socket side wing 11 and the concrete pipe body 1, and the socket slot 12 is a through groove matching the socket side wing 11. When in use, the socket side wing 11 is inserted from one side of the socket slot 12. Since the shapes of the socket 12 and the socket wing 11 match, they play a guiding role in the installation of the concrete pipe segment body 1, and then a connecting side plate 272 corresponding to the shape of the side reinforcing rib 271 is buried on the inner side of the socket 12, and a plurality of through holes are opened on the connecting side plate 272, and a plurality of through sleeves 273 extend from both sides of the plurality of through holes, and the plurality of through sleeves 273 pass through both sides of the socket 12. The connecting side plate 272 arranged on the inner side of the socket 12 supports and strengthens the socket 12, and serves as an anchor point when connecting the pipe segments.

[0066] According to the instruction manual Figure 1 -Attached Figure 6 It can be seen that the above-mentioned concrete pipe segment body 1 is pre-embedded with an embedded component 28, and the embedded component 28 is connected with the steel frame 2 to play a role in connecting and locking with other pipe segment structures. Specifically, the embedded component 28 is arranged on the side reinforcing rib 271 and the connecting side plate 272. When a pair of adjacent concrete pipe segment bodies 1 are plugged and matched, the socket side wing 11 of one concrete pipe segment body 1 is inserted into the socket 12 of the other concrete pipe segment body 1. When the socket side wing 11 on one concrete pipe segment body 1 is inserted into the socket 12, the large-volume trapezoidal block structure of the single socket side wing 11 effectively improves the connection contact area and bearing capacity between the socket side wing 11 and the socket 12, and the embedded side reinforcing rib 271 and the connecting side plate 272 play a further reinforcing role.

[0067] Specifically, the embedded component 28 includes a plurality of threaded seats 281, and a plurality of threaded seats 281 are arranged in a linear array on one side of the side reinforcement rib 271. A plurality of embedded pipes 282 are threadedly connected to the plurality of threaded seats 281. The positions of the plurality of embedded pipes 282 correspond to the positions of the plurality of through sleeves 273 and penetrate the socket 12.

[0068] During the specific implementation process, the embedded component 28 also includes a plurality of fastening bolts 283. When the socket side wing 11 is connected to the socket socket 12, the fastening bolts 283 pass through the sleeve 273 and are threadedly connected in the embedded pipe 282, so that the fastening bolts 283 are pulled back through the sleeve 273 and are threadedly connected to the embedded pipe 282, thereby strengthening the connection between the socket socket 12 and the socket side wing 11, and during pouring, they are connected to the anchor point in the pouring mold through the embedded pipe 282, thereby fixing the steel frame 2.

[0069] Furthermore, the reinforcing component 26 includes a reverse pull ring 261, which is wrapped around the outside of the transverse rib 24 and welded to the positioning plate 21 at both ends. The middle section of the reverse pull ring 261 is welded to the side of the reinforcing rib 25. The reverse pull ring 261 is a semi-annular reverse buckle structure that wraps around the outside of the transverse rib 24, thereby strengthening the fixed connection between the positioning plate 21 and the reinforcing rib 25.

[0070] Embodiment 2: According to the specification sheet Figure 7 -Attached Fig.12 It can be seen that in order to cooperate with the above-mentioned pipe segment processing, the present application also discloses a processing equipment for rail concrete high-strength pipe segments, including a casting platform 3 and a mold base 4, the casting platform 3 is arranged above the mold base 4, and a pair of guide rails are arranged at the bottom of the mold base 4; during the casting process of the concrete pipe segment body 1, the casting assembly is integrated using the casting platform 3, a casting shell 5 is arranged on the mold base 4, and the casting shell 5 is supported by the mold base 4, and the mold base 4 can be transported and moved between different processing stations using a pair of guide rails, so as to facilitate the casting and molding of the concrete pipe segment body 1;

The mold clamp 6 is used to close the top surface opening of the casting shell 5. The closing effect of the casting shell 5 is achieved by controlling the switch of the mold clamp 6. This facilitates the shaping of the pipeline during casting and facilitates maintenance operations after the casting is completed. The casting shell 5 is an arc-shaped groove with an opening on the top. A casting inlet 61 is provided on the top of the mold clamp 6. The casting inlet 61 corresponds to the casting platform 3, which facilitates the concrete to fall accurately from the casting inlet 61 into the casting shell 5 during the casting process.

[0072] According to the instruction manual Figure 7 -Attached Fig.12 It can be seen that the pouring platform 3 is provided with a pouring controller, which includes a pouring bucket 31. A pouring pipe 32 extends from the bottom of the pouring bucket 31. A control gate 33 is provided on the pouring pipe 32.

A casting scraper 9 is arranged on the positioning guide frame 8, and the casting scraper 9 can move along the positioning guide frame 8. Through the function of the positioning guide frame 8, the cast concrete pipe segment body 1 can be scraped and leveled.

[0074] In order to avoid bubbles in the concrete during the pouring process, a vibrating structure 7 is provided on the mold base 4.

The two pairs of lifting rails 82 are connected to the guide frame 83. The lifting rails 82 are used to connect the guide frame 83 and the fixed frame 81. When the guide frame 83 is lifted or lowered, the lifting rails 82 are used to guide and limit the guide frame 83, so as to prevent the guide frame 83 from shaking during the lifting process.

[0077] According to the instruction manual Figure 7 -Attached Fig.12It can be known that a horizontal screw rod module 84 is provided on the guide frame 83, and a pair of guide seats 85 are provided on the pair of screw rod modules 84. The pair of guide seats 85 can be controlled to move horizontally through the pair of horizontal screw rod modules 84. A pair of lifting sleeves 91 are provided on the pair of guide seats 85. The pair of guide seats 85 can drive the pair of lifting sleeves 91 to move. The movement range of the pair of guide seats 85 covers the upper part of the entire casting shell 5. A pair of lifting rods 92 are inserted in the pair of lifting sleeves 91. The bottom of the pair of lifting rods 92 is connected to a guide wheel 93. A pair of arc grooves 94 are provided on both sides of the casting shell 5 corresponding to the pair of guide wheels 93. A scraper 95 is connected between the pair of lifting rods 92. The scraper 95 is parallel to the curvature of the casting shell 5. The bottom end of the scraper 95 penetrates 5-10mm below the top surface of the casting shell 5. When scraping flat, the mold clamp 6 is opened and the pair of lifting rods 92 are moved. The pair of lifting rods 92 are connected by a cross bar, and a pair of lifting rods 92 move horizontally with the pair of lifting sleeves 91, and the pair of lifting rods 92 always have a tendency to move downward under the action of the lifting spring in the lifting sleeve 91. When scraping, the pair of guide wheels 93 at the bottom ends of the pair of lifting rods 92 contact the pair of arc grooves 94, and the pair of arc grooves 94 guide the pair of guide wheels 93, so that the pair of guide wheels 93 can move horizontally and match the height change of the casting shell 5, so that the pair of lifting rods 92 can be lifted and lowered in the lifting sleeve 91, and then the scraper 95 between the pair of lifting rods 92 moves synchronously with the pair of lifting rods 92. Since the guide wheel 93 can move with the curvature of the casting shell 5, the scraper 95 is always kept at a fixed height from the top surface of the casting shell 5, and the scraper 95 passes through the top surface of the concrete pipe segment body 1 to complete the scraping construction of the top surface of the concrete pipe segment body 1.

[0078] According to the instruction manual Figure 7 -Attached Fig.12 It can be seen that a mounting groove is provided on the mold base 4, and the mounting groove matches the structure of the casting shell 5. A number of fixing holes are provided on the mounting groove. A number of fixing rods are provided on the bottom surface of the casting shell 5. The number of fixing rods pass through the number of fixing holes. The bottom ends of the number of fixing rods are provided with horizontal detachable bolts connected to the mold base 4. In the specific implementation process, the mounting groove serves as a space for installing equipment in the mold base 4. Through the corresponding action of the fixing rods and the fixing holes, it plays a supporting and limiting role when the casting shell 5 is placed in the mold base 4.

[0079] Furthermore, a plurality of pairs of reinforcing sealers are symmetrically arranged on both sides of the mold base 4, and the plurality of pairs of reinforcing sealers are connected to both sides of the mold clamp 6 by pulling;

[0080] According to the instruction manual Figure 7 -Attached Fig.12It can be seen that the above-mentioned reinforcement sealer includes a reinforcement groove 42, which is arranged on a side wall of the mold base 4, and a threaded hole is opened on the reinforcement groove 42, and an adjusting bolt 43 is threadedly connected to the threaded hole, and the end of the adjusting bolt 43 is connected to a clamping block 44 through a chain, and a plurality of pairs of clamping grooves 62 are symmetrically arranged on both sides of the mold clamp 6. After the clamping block 44 at the corresponding position is placed in the clamping groove 62, the clamping block 44 is reversely pulled and locked by the adjusting bolt 43;

[0081] In the specific implementation process, the threaded hole on the reinforcement groove 42 is threadedly connected with the adjusting bolt 43, so that the adjusting bolt 43 can move linearly in the reinforcement groove 42. When the mold clamp 6 is closed, the clamping block 44 is clamped into the clamping groove 62, and then the adjusting bolt 43 is rotated to engage with the threaded hole, so that the adjusting bolt 43 moves linearly to tighten the chain, and the clamping block 44 is fully matched with the clamping groove 62, so that the mold clamp 6 is buckled on the casting shell 5, ensuring that the mold clamp 6 is closed more tightly.

[0082] According to the instruction manual Figure 7 -Attached Fig.12 It can be known that the above-mentioned vibration structure 7 includes a vibration chute 71, a vibration chute 71 is arranged on the mold base 4 along the curvature of the casting shell 5, a sliding arc plate 72 is arranged on the vibration chute 71, and the sliding arc plate 72 is assembled in the vibration chute 71. A vibration guide control assembly 73 is arranged in the mold base 4 and connected to the sliding arc plate 72. At least three vibrators 74 are arranged on the sliding arc plate 72 corresponding to the center line of the casting shell 5 and on both sides.

[0083] In the specific implementation process, the vibration chute 71 matches the curvature of the casting shell 5, and the sliding arc plate 72 is assembled in the vibration chute 71. The sliding arc plate 72 can be controlled to move by using the vibration guide control component 73, so that the sliding arc plate 72 drives the vibrator 74 to move. The movement range of the vibrator 74 covers most of the bottom surface of the casting shell 5, and the vibrating end of the vibrator 74 is arranged in contact with the bottom surface of the casting shell 5. During casting, the vibrator 74 is driven by the sliding arc plate 72 to move at a uniform speed within the coverage range of the bottom surface of the casting shell 5. Since the vibrator 74 contacts the bottom surface of the casting shell 5, the vibration effect of the vibrator 74 is transmitted to the casting shell 5, and the vibration is transmitted to the concrete, causing the concrete to vibrate slightly, so that the bubbles therein are discharged and the concrete is distributed more evenly in the casting shell 5.

[0084] Further, according to the instructions attached Figure 7 -Attached Fig.12It can be seen that the above-mentioned vibration guide control assembly 73 includes an arc guide rail 731, the inner side of the mold base 4 is provided with an arc guide rail 731, the bottom surface of the sliding arc plate 72 extends out a power control board 732, the power control board 732 is provided with a guide control motor 733, the driving end of the guide control motor 733 is connected to a guide gear set 734, and the arc guide rail 731 is provided with an arc tooth groove 735 corresponding to the guide gear set 734, and the arc tooth groove 735 is meshed with the guide gear set 734;

[0085] During the specific implementation process, the curvature of the arc guide rail 731 matches the curvature of the casting shell 5, and the power control board 732 is used to install the guide control motor 733. The guide control motor 733 drives the guide gear set 734 to move, thereby making the guide gear set 734 engage with the arc tooth groove 735, and the sliding arc plate 72 is pushed to move under the reverse thrust of the arc tooth groove 735. The sliding arc plate 72 can only move along a fixed path due to the limitation of the vibrating groove 71. By controlling the forward and reverse rotation of the guide control motor 733, the movement direction of the sliding arc plate 72 is controlled, thereby making the sliding arc plate 72 drive the vibrator 74 thereon to move at a uniform speed.
