Description

Technical Field

[0001] The invention relates to the field of subway channel support, and in particular to a construction method of a corrugated plate support structure and a subway cross channel. Background Art

[0002] During the construction of subway cross-passages, steel gratings and shotcrete are required for initial support. This type of support method uses electric welders and shotcrete mixtures, which will produce smoke and dust pollution to the surrounding environment. In addition, compared with the prefabricated support method, the traditional initial support method has more processes and low construction efficiency, which affects the construction progress.

[0003] However, the support strength of the prefabricated support method is relatively low because it is a spliced ​​ring structure. Summary of the invention

[0004] The object of the present invention is to provide a construction method of a corrugated plate support structure and a subway cross passage, which can effectively improve the support strength of the assembled support method.

[0005] The embodiment of the present invention is achieved as follows:

[0006] A construction method of a corrugated plate support structure comprises the following steps:

[0008] Step 2: Go up the steps and set up the waist beam;

[0009] Step 3: erect the upper step corrugated plate, erect the upper step circular waist beam, and install the longitudinal channel steel;

[0010] Step 4: After a certain distance of construction on the steps, stop construction;

[0011] Step 5: Remove the steps under the horse head gate;

[0012] Step 6: Go up the steps and set up the waist beam;

[0013] Step 7: erect the upper step corrugated plate, erect the upper step annular waist beam, and install the longitudinal channel steel;

[0014] Step 8: After forming a ring, backfill and inject grout behind the corrugated plate;

[0015] Step nine, repeat steps one to eight.

[0016] In a preferred embodiment of the present invention, in step three, the corrugated plates and the annular waist beams are erected to perform a cyclic construction.

[0017] In a preferred embodiment of the present invention, in step three, after the annular waist beam is erected, the contraction anchor rods are installed.

[0018] In a preferred embodiment of the present invention, when the upper step corrugated board is erected in step three, a temporary support is added to the upper step, and both sides of the temporary support are connected to the annular waist beam.

[0019] In a preferred embodiment of the present invention, the bottom of the temporary support needs to be padded, and the actual height can be adjusted by using a jack.

[0020] In a preferred embodiment of the present invention, in step three, the corrugated plate at the arch line position and the node of the ring waist beam are connected by a three-sided socket method.

[0021] In a preferred embodiment of the present invention, in step 4, the certain distance for the step construction is 2 meters to 5 meters.

[0022] In a preferred embodiment of the present invention, a flange is provided on the corrugated plate. When erecting the upper step corrugated plate or the lower step corrugated plate, the flanges on the adjacent corrugated plates are connected by bolts to realize the erection of the corrugated plates.

[0023] In a preferred embodiment of the present invention, when adjacent corrugated plates are connected, a sealing gasket is arranged between two flanges connected by bolts to prevent water seepage between the corrugated plates.

[0024] A subway cross passage is constructed using any of the above-mentioned construction methods for the corrugated plate support structure.

[0026] By setting up the inner supporting ring belt and the outer supporting ring beam, the overall supporting strength of the transverse channel is greatly improved, ensuring the supporting effect of the transverse channel.

[0027] The setting of the annular plate belt and the annular waist beam of the inner support ring belt ensures that it can carry out large-area support, and does not require a large number of external support ring beams. While ensuring the support strength, the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In the present invention, the construction process of the corrugated plate support structure is as follows:

[0048] 1. Strengthen the horse head door;

[0049] 2. The steps on the horse head gate are removed;

[0050] 3. The circular waist beam of the first step is erected and the foot locking anchor rods are installed;

[0051] 4. The corrugated plate of the upper step is erected, the circular waist beam 6 of the upper step is erected, the circular waist beam 6 is provided with locking anchor rods, and the longitudinal channel steel is installed (the third part is the circular construction);

[0052] 5. Set up temporary supports;

[0053] 6. When the construction progress of the steps reaches about 3m, the cover work will be stopped;

[0054] 7. The steps under the horse head gate are removed;

[0055] 8. The first circular waist beam of the lower step is erected to form a ring with the circular waist beam 6 of the upper step, and the locking foot anchor rods are installed;

[0056] 9. The corrugated plate of the lower step is erected, the annular waist beam 6 of the lower step is erected, the locking anchor rods are set on the annular waist beam 6, and the longitudinal channel steel 25 is installed. After each ring is formed, the back of the initial support is backfilled with grouting;

[0057] 10. Removal of temporary supports;

[0058] 11. Go up and down the steps in a circular motion and proceed forward.

[0059] The construction process of the corrugated plate support structure is simple and the construction efficiency is effectively improved. The main process is: earth excavation + corrugated plate installation (bolt connection) + backfill grouting behind the initial support.

[0060] The use of corrugated plate support structure construction effectively solves the cumbersome problems of traditional construction technology, improves construction efficiency, reduces labor costs, and speeds up production progress.

[0061] Installation of the upper step of the first frame: set 1 point on the upper part of the arch, and set 1 point each above the arch foot of the upper steps on both sides, and determine the position of the first frame ring waist beam through the downward return values ​​of these three points.

[0062] In the present invention, during the installation of the corrugated plate, temporary supports 24 can be added on the upper step to consider the sinking of the arch. Figure 8 and Fig.10 As shown, node plates are provided on both sides of the temporary support 24 and are bolted to the node plates of the ring beam. The corrugated plate arch foot and the bottom of the temporary support need to be padded. After the corrugated plate of the lower step is formed into a ring, the temporary support is removed and used alternately.

[0063] By setting up temporary supports, the construction accuracy can be improved and settlement can be reduced.

[0064] Specifically, Figure 8 As shown, the temporary support includes a transverse support 14 and a vertical support 13. The transverse support 14 is located on the core soil 15. A pressure relief groove 16 is arranged below the core soil 15. The vertical support 13 is erected on the transverse support 14. Bases 11 are arranged on both sides of the transverse support 14 and on the top of the vertical support 13. The base 11 supports the corrugated plate 5.

[0065] Temporary support is only applied when the structure has not formed a ring. In order to facilitate reuse, an adjustment device 12 is set between the base 11 and the steel support to adjust the support length by hand-tightening.

[0066] Specifically, Fig. 9 As shown, the adjusting device 12 includes an upper plate 17 , a lower plate 20 , a fixing sleeve 19 , a fixing rod 18 , an upper adjusting rod 23 , a lower adjusting rod 22 and an adjusting sleeve 22 .

[0067] The upper plate 17 and the lower plate 20 are arranged parallel to each other, a plurality of fixed rods 18 are arranged on the upper plate 17, a plurality of fixed sleeves 19 are arranged on the lower plate 20, and the fixed sleeves 19 are sleeved on the fixed rods 18; the upper adjusting rod 23 is fixedly arranged on the upper plate 17, and the lower adjusting rod 22 is fixedly arranged on the lower plate 20, the upper end of the adjusting sleeve 22 is threadedly connected to the upper adjusting rod 23, and the lower end of the adjusting sleeve 22 is rotatably connected to the lower adjusting rod 22, and the spacing between the upper plate 17 and the lower plate 20 is adjusted by means of a threaded screw, so that the disassembly and fixation of the steel support can be facilitated, and it can be reused.

[0068] More specifically, a rotary hoop 24 is provided on the lower adjusting rod 22 , the outer portion of the rotary hoop 24 is convex, and a steel ball is provided on the rotary hoop 24 , which not only ensures the rotation effect of the adjusting sleeve 22 , but also enables axial positioning of the adjusting sleeve 22 .

[0069] The corrugated plate at the arch line position and the ring waist beam node are connected by three-sided socket method; the corrugated plate and the ring waist beam nodes in other parts are staggered, and the bolt holes are appropriately increased and adjusted at the ring waist beam joints.

[0070] The construction of corrugated plate support structure is controlled from the processing of corrugated plate. The corrugated plate is processed by factory-style CNC machine tools, which mechanically control the cutting of raw materials, rolling of plates into waves, laser cutting of flanges, and laser cutting of reserved holes. The accuracy of CNC processing control parameters is higher than that of grille arch processing. The high accuracy of corrugated plate reduces the chance of errors during installation.

[0071] The corrugated plate is installed and connected using flanges and bolts, which makes it easier to determine the installation dimensions and improves construction accuracy.

[0072] During the construction of the corrugated plate support structure, the corrugated plates are processed in the factory according to the design drawings and backfill grouting joints are reserved. The corrugated plates are installed according to the drawings. When the mileage of backfill grouting is reached, the backfill grouting pipe joints can be directly connected on site to carry out backfill grouting behind the initial support, thereby improving construction efficiency, accuracy and standardization.

[0073] During the construction of the corrugated plate support structure, in order to solve the problem of groundwater seeping from the joints of the corrugated plate flanges, waterproof rubber pads are added to the joints of the corrugated plate flanges, and initial backfill grouting is carried out in time during the construction of the corrugated plate. At the same time, longitudinal channel steel is installed on the inside of the corrugated plate to prevent uneven settlement of the corrugated plate, which causes water seepage at the flange joints and ensures the safety of tunnel construction.

[0074] The following is combined with Figure 2-Figure 7 , the structures used in some embodiments of the present invention are described in detail. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other, or the above embodiments and features in the embodiments can be combined with each other.

[0075] A corrugated plate support structure includes an inner support ring belt 3 and an outer support ring beam; the inner support ring belt 3 is arranged in the outer support ring beam, and the inner wall of the inner support ring belt 3 is tangent to the inner wall of the outer support ring beam; the inner support ring belt 3 includes n support plate belts and n+1 annular waist beams 6, and the support plate belts are arranged between two adjacent annular waist beams 6; the annular waist beams 6 at both ends of the inner support ring belt 3 are connected to the outer support ring beam.

[0076] In this embodiment, by providing the inner supporting ring belt 3 and the outer supporting ring beam, the inside and the outside are combined, which can effectively increase the stability and support strength of the corrugated plate support structure.

[0077] Specifically, in this embodiment, the inner support ring belt 3 includes a support plate belt and an annular waist beam 6. The support plate belt mainly plays a role of large-area support, and the annular waist beam 6 is equivalent to the skeleton of the inner support ring belt 3, which can play a role in improving the supporting force and stability.

[0078] During the specific installation process, both ends of each support plate belt are fixedly connected to the annular waist beam 6, that is, the installation sequence is the structure of annular waist beam 6, support plate belt, annular waist beam 6, support plate belt, and annular waist beam 6, that is, the two ends of the inner support ring belt 3 are annular waist beams 6, which are fixedly connected to the outer support ring beam through the annular waist beam 6, thereby ensuring the strength and stability of the connection.

[0079] In this embodiment, the number of annular waist beams 6 contained in each inner supporting ring band 3 is not necessarily the same, but the number of annular waist beams 6 in each inner supporting ring band 3 is one more than the number of supporting plate bands to ensure the connection strength and connection stability between the supporting plate band and the outer supporting ring beam.

[0080] When in use, after the outer supporting ring beam and the inner supporting ring belt 3 are installed on the outer wall, grouting is performed to the outer side of the overall corrugated plate support structure through the opening on the inner supporting ring belt 3 to form a grouting layer 4. At this time, the mortar of the grouting layer 4 will fix the outer supporting ring beam as a whole, and due to the fixed connection between the inner supporting ring belt 3 and the outer supporting ring beam, the stability of the inner supporting ring belt 3 is greatly improved, thereby greatly improving the support strength and support effect of the cross channel.

[0081] In a preferred embodiment of the present invention, the support plate belt includes a plurality of corrugated plates 5, and the corrugated plates 5 are sequentially connected to form a ring.

[0082] In this embodiment, the support plate belt is an annular belt structure formed by connecting a plurality of corrugated plates 5 in sequence.

[0083] The initial corrugated plate support structure system with the corrugated plate 5 as the main load-bearing member has a unique structural advantage. Its axial and radial bidirectional load-bearing increases the radial stiffness of the structure. The longitudinal corrugations can also play a role in displacement compensation, better adapting to the uneven deformation of the surrounding rock. Especially for underground tunnels, the greater deformation of the surrounding rock can give play to the advantages of the annular and longitudinal bidirectional load-bearing of the corrugated plate 5, dispersing the load effect of the vertical earth pressure. The overall flexible load-bearing greatly improves the seismic resistance and fatigue performance of the structure, and gives full play to the isotropic characteristics of steel. When using the corrugated plate 5 as a plate support structure, it can be adjusted to a cross-sectional type with different cross-sectional forms (horseshoe-shaped, pear-shaped, tubular, box-shaped, circular, etc.) according to the characteristics of the stratum and the use requirements.

[0084] In a preferred embodiment of the present invention, an axial fixing beam is further provided on the inner wall of the inner supporting ring belt 3 , and the axial fixing beam is fixedly connected to the annular waist beam 6 .

[0085] By setting the axial fixed beam, the adjacent annular waist beams 6 are connected together to form a complete skeleton structure, which can effectively increase the support strength and support stability of the inner support ring belt 3.

[0086] Specifically, there are two ways to set the axial fixed beam. One way is that the two ends of the axial fixed beam are respectively fixedly connected to the side walls of the annular waist beam 6 that are connected to the corrugated plate 5. The other way is that the length of the axial fixed beam is the same as the width of the inner support ring belt 3, and it is fixedly set on the inner side of the annular waist beam 6 and connected to all the annular waist beams 6.

[0087] More specifically, in this embodiment, the fixed connection method between the axial fixed beam and the annular waist beam 6 can be bolt connection, or it can be welding, riveting, etc., as long as it can achieve the fixed setting of the axial fixed beam on the annular waist beam 6.

[0088] In a preferred embodiment of the present invention, the length direction of the axial fixed beam is parallel to the axis of the support ring belt, that is, the axial fixed beam is perpendicular to the annular waist beam 6, thereby ensuring the strength and stability of the entire inner support ring belt 3 to the greatest extent.

[0089] It should be pointed out that the axial fixed beam and the annular waist beam 6 can be vertical or non-vertical. It can be set according to the specific conditions of the transverse channel as long as the support strength of the inner support ring belt 3 can be guaranteed.

[0090] In a preferred embodiment of the present invention, the outer supporting ring beam comprises a horizontal beam 1 and a vertical beam 2, and the horizontal beam 1 and the vertical beam 2 are connected in sequence to form a square ring beam.

[0091] Specifically, the outer support ring beam retains two horizontal beams 1 and two vertical beams 2. During the specific installation, Figure 3 As shown, the cross beam 1 and the vertical beam 2 are both fixedly connected to the annular waist beam 6 at the end of the inner supporting ring belt 3.

[0092] In this embodiment, the specific fixing connection method is bolt connection.

[0093] It should be pointed out that the fixed connection between the cross beam 1 and the annular waist beam 6 and between the vertical beam 2 and the annular waist beam 6 can be bolted, or can be other fixed connection methods such as riveting and welding.

[0094] More specifically, after the inner support ring belt 3 and the outer support ring beam are installed, since the annular waist beam 6 is arc-shaped and the horizontal beam 1 and the vertical beam 2 are straight, after the two are fixedly connected, a gap will be formed between the two annular waist beams 6, making some positions unable to be supported.

[0095] To avoid the above situation, in the present embodiment, a special-shaped annular waist beam 6 is arranged between two adjacent annular waist beams 6 at this position, that is, part of the overall annular waist beam 6 is cut off to form an arc-shaped waist beam for supplementary support, and the two ends of the arc-shaped waist beam are respectively fixedly connected to the inner walls of the horizontal beam 1 and the vertical beam 2, and the two opposite side walls of the arc-shaped waist beam are respectively fixedly connected to the annular waist beam 6, thereby ensuring the complete support of the horizontal channel.

[0096] In a preferred embodiment of the present invention, both the cross beam 1 and the vertical beam 2 include an inner profile and an outer connecting plate 7; the outer connecting plate 7 is arranged on two opposite sides of the inner profile.

[0097] In this embodiment, both the cross beam 1 and the vertical beam 2 include internal forming and external connecting plates 7. Through the provision of the external connecting plates 7, a plurality of internal profiles can be formed into a whole, thereby ensuring the overall supporting strength.

[0098] Specifically, a plurality of internal profiles are arranged side by side and then connected through external connection plates 7 arranged on opposite sides to form a complete whole.

[0099] In this embodiment, in order to facilitate the installation between the horizontal beam 1 and the vertical beam 2, an end plate 9 is provided at the end of the internal profile, and the external connecting plate 7, the end plate 9, and the external connecting plate 7 are connected in sequence to form a U-shaped structure, which can better ensure the strength and stability between the multiple internal profiles.

[0100] like Figure 7 As shown, when the cross beam 1 and the vertical beam 2 are fixedly connected, the end plate 9 of the cross beam 1 can be abutted against the outer connection plate 7 of the vertical beam 2 and then fixedly connected by bolts.

[0101] More specifically, in a preferred embodiment of the present invention, the internal profile is a double-jointed I-beam 8 .

[0102] In this embodiment, the strength of the I-beam 8 is relatively high, and it can meet the support requirements of the transverse passage after being arranged in pairs.

[0103] Specifically, in this embodiment, the upper and lower end surfaces of the I-beam 8 are fixedly connected to the outer connecting plate 7 .

[0104] More specifically, in a preferred embodiment of the present invention, the outer connecting plate 7 is provided with a mounting hole 10 for cooperating with a bolt to achieve connection with the inner support.

[0105] In order to reduce the number of mounting holes 10 on the outer connecting plate 7, in this embodiment, when the horizontal beam 1 or the vertical beam 2 is connected to the annular waist beam 6, the mounting holes 10 at the connection position are arranged corresponding to the mounting holes 10 on the annular waist beam 6, and the installation can be achieved using the same bolt.

[0106] In a preferred embodiment of the present invention, the vertical beam 2 is formed by splicing multiple beams.

[0107] In a normal transverse passage, generally, the height is relatively high, and thus the required length of the vertical beam 2 is also longer. In order to facilitate transportation, in this embodiment, the vertical beam 2 is configured to be spliced ​​together.

[0108] Specifically, the shorter vertical beams 2 are prefabricated in a factory, transported to a construction site, and then spliced ​​to reach a preset height.

[0109] Since the cross beam 1 requires a relatively large support force, in this embodiment, it is generally not recommended to splice multiple cross beams 1 .

[0110] A subway cross passage is constructed using any of the construction methods described above.

[0111] The beneficial effects of the embodiments of the present invention are:

[0112] By setting the inner supporting ring belt 3 and the outer supporting ring beam, the overall supporting strength of the transverse channel is greatly improved, ensuring the supporting effect of the transverse channel.

[0113] The arrangement of the annular plate belt and the annular waist beam 6 of the inner supporting ring belt 3 ensures that it can carry out large-area support without the need for a large number of outer supporting ring beams, thereby reducing costs while ensuring the support strength.

[0114] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
