Description

Technical Field

[0001] The invention relates to the field of corrugated plate support, and in particular to a mold bag concrete corrugated plate support structure. Background Art

[0002] Tunnel support structure is a vital part of tunnel engineering. Its design and construction have an important impact on the stability, safety and durability of the tunnel. The existing tunnel support structure usually adopts the method of shield segments combined with concrete tamping. When this method is used, due to the characteristics of the tamping molding process, the cubic specimens of traditional building materials concrete have poor compressive mechanical properties, and the existing shield segments have low strength to withstand surrounding rock deformation. At the same time, the existing shield segments are relatively thick and heavy, which is not convenient for transportation, maintenance and construction.

[0003] For example, the "corrugated plate tunnel initial support structure and tunnel" disclosed in the Chinese invention patent (application number: CN202010422368.2) discloses in its specification: When constructing interval tunnels in urban underground projects, in order to close the excavation surface as soon as possible and effectively reduce surface settlement, an initial support device with greater rigidity should be erected as soon as possible after soil excavation. At present, in the construction of subway interval tunnels using the mining method, the initial support method of spray anchor is adopted, that is, the spray layer, anchor rods and surrounding rock together form a ring-shaped bearing structure, which bears the pressure of the surrounding rock and forms an initial support structure. This type of initial support device is a steel grating formed by welding multiple steel bars or a steel grating structure formed by bending steel sections. In the initial support device of the prior art, each ring of the steel grating steel frame is assembled from several grating units of different shapes. Each frame of the steel grating is welded by main bars, reinforcing bars and connecting angle steels (forming end plates), and the units are connected by high-strength bolts. In actual application, the steel grating after layout will be adjusted and connected according to the pre-designed unit positions. When the grating is erected, the system anchor rods will be driven into the soil to fix the position of the grating. When the system anchor rods are not set, the steel grating can also be positioned by locking anchor rods. After the above-mentioned grating is erected, the concrete is sprayed in layers as soon as possible to form a composite force-bearing structure of the steel grating and sprayed concrete. However, the initial support device used in underground projects in the prior art, because the entire construction process of the initial lining structure of the underground project includes the transportation, installation, connection, and adjustment of the grating steel frame, as well as the two major links of concrete material preparation, air compression equipment, transportation pipelines, and spraying assembly, the installation of the existing initial support device generally requires a long construction time, and it is difficult to truly realize the "quick closure" principle of tunnel excavation support; the above-mentioned patent can prove the defects of the prior art.

[0045] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0046] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0048] Example 1, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A corrugated plate support structure for mold bag concrete, wherein the inner rectangular array of the guard plate 101 has a connecting groove 106, and the connecting groove 106 is connected with the first material transport trough 103, the guard plate 101 is sleeved with the rotating shaft 105 through the connecting groove 106, and the outer side of the rotating shaft 105 has a sealing ring, and the rotating shaft 105 is squeezed and sealed with the guard plate 101 through the sealing ring.

[0049] By rotating the rotating shaft 105 to rotate it to the outside of the guard plate 101, the guard plate 101 can be supported by the rotating shaft 105. By rotating the rotating shaft 105 to completely accommodate it in the connecting groove 106, the connecting groove 106 can also be sealed and connected.

[0050] Further, such as Figure 4 , Figure 5 , Figure 6 and Fig.11 As shown, the internal rectangular array of the guard plate 101 has a connecting groove 106, and the connecting groove 106 is connected to the first material transport trough 103. The guard plate 101 is connected to the rotating shaft 105 through the connecting groove 106. The outer side of the rotating shaft 105 has a sealing ring, and the rotating shaft 105 is squeezed and sealed with the guard plate 101 through the sealing ring.

[0051] By rotating the rotating shaft 105 to rotate it to the outside of the guard plate 101, the guard plate 101 can be supported by the rotating shaft 105. By rotating the rotating shaft 105 to completely accommodate it in the connecting groove 106, the connecting groove 106 can also be sealed and connected.

[0052] Further, such as Figure 7 , Figure 8 , Fig.11 and Fig.12 As shown, a telescopic shaft 107 is provided at one end of the rotating shaft 105, and the guard plate 101 is sleeved with the telescopic shaft 107 through the first material transport groove 103. A compression spring 108 is fixedly installed at one end of the telescopic shaft 107 away from the rotating shaft 105, and a ring plate 109 is fixedly installed at the other end of the compression spring 108. The ring plate 109 is located at one end of the first material transport groove 103.

[0053] When the rotating shaft 105 rotates, the compression spring 108 will be squeezed through the telescopic shaft 107, and the telescopic shaft 107 will move along the first material transport trough 103. When the rotating shaft 105 is completely retracted to the inside of the guard plate 101, the telescopic shaft 107 will penetrate the rotating shaft 105 and extend into the inside under the action of the compression spring 108, thereby connecting the first material transport trough 103 through the telescopic shaft 107.

[0054] Further, such as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a connecting tube 110 is provided at the other end of the rotating shaft 105, and the guard plate 101 is sleeved with the connecting tube 110 through the first material transport trough 103. A side groove 113 is opened on the inner side of the connecting tube 110, and the extrusion block 111 passes through the side groove 113 and extends to the inside of the connecting tube 110, and the bottom of the extrusion block 111 is inclined, the size of the middle part of the extrusion block 111 is the same as the size of the side groove 113, and the outer side of the extrusion block 111 has a sealing ring.

[0055] The extrusion block 111 is clamped by the clamping assembly, thereby driving the entire guard plate 101 to move and push the extrusion block 111, so that the extrusion block 111 passes through the side groove 113 and continuously extends into the interior of the connecting tube 110 until the side wall of the extrusion block 111 is in full contact with the side groove 113, thereby sealing the side groove 113 through the sealing ring sleeved in the middle of the extrusion block 111.

[0056] Further, such as Fig.10 As shown, a spring piece 114 is fixedly mounted on the inner side of the connecting tube 110 , and the spring piece 114 is arranged obliquely. The spring piece 114 is located at one side of the side groove 113 .

[0057] Further, such as Figure 7 , Figure 8 and Fig. 9 As shown, a clamping plate 115 is symmetrically installed at one end of the spring piece 114 away from the side groove 113, and the clamping plate 115 is arc-shaped. A limiting shaft 112 is symmetrically installed on the outer side of the extrusion block 111. The limiting shaft 112 is located inside the connecting tube 110, and the limiting shaft 112 matches the clamping plate 115.

[0058] By moving the extrusion block 111, the spring sheet 114 is squeezed. The spring sheet 114 is deformed when being squeezed, and the extrusion block 111 is continuously moved. The side groove 113 can also continuously push the connecting tube 110 to move, so that the connecting tube 110 passes through one end of the rotating shaft 105 and extends to the inner side thereof. The extrusion block 111 is continuously moved until the limiting shaft 112 is engaged with the clamping plate 115, thereby fixing the extrusion block 111 and the connecting tube 110.

[0059] Further, such as Figure 3 and Figure 4 As shown, the outer array of the guard plate 101 is provided with a first discharge chute 104 , one end of the first discharge chute 104 is connected to the first material transport chute 103 , and the other end of the first discharge chute 104 is connected to the first mold bag 102 .

[0060] Example 2, please refer to Fig.13 and Fig.14 A mold bag concrete corrugated plate support structure, specifically, the top cover assembly 2 includes a top plate 201 arranged above the protective pipe assembly 1, the top plate 201 is arc-shaped, and the top plate 201 is made of steel corrugated pipe, and the two ends of the top plate 201 are respectively in contact with the two groups of protective plates 101.

[0061] Furthermore, Fig.13 and Fig.14 A second mold bag 202 is fixedly installed on the outer side of the top plate 201, a second material transport trough 204 is symmetrically opened inside the top plate 201, and the second material transport trough 204 is connected to the first material transport trough 103, and a second discharge trough 205 is symmetrically opened on the outer side of the top plate 201, one end of the second discharge trough 205 is connected to the second material transport trough 204, and the other end of the second discharge trough 205 is connected to the second mold bag 202.

[0062] Furthermore, Fig.13 and Fig.14 A feed pipe 203 is symmetrically installed on the inner side of the top plate 201 , and one end of the feed pipe 203 is connected to the second material transport trough 204 .

[0063] Concrete is poured into the second transport chute 204 under pressure through the feed pipe 203 , and the concrete is transported to the second mold bag 202 through the second discharge chute 205 .

[0064] The use process of the mold bag concrete corrugated plate support structure provided by the present invention is as follows:

[0065] When in use, since the guard plates 101 are in a stacked state, the rotating shaft 105 sleeved inside the bottom guard plate 101 is tilted and contacts the stacking surface, thereby supporting the stacked guard plates 101, and the bottom of the tilted rotating shaft 105 inside the upper guard plate 101 extends to the inside of the connecting groove 106 provided in the guard plate 101 below it, and at the same time, the rotating shaft 105 is directly engaged with the connecting groove 106, thereby achieving one-time stacking;

[0066] When in use, first take out a set of guard plates 101, and clamp the extrusion blocks 111 that penetrate the array inside the guard plates 101 through the clamping device, and place the guard plates 101 in an appropriate position. At this time, the rotating shaft 105 is still in an inclined state, but as the guard plates 101 are constantly in contact with the inner wall of the tunnel, the rotating shaft 105 is constantly squeezed during the movement, so that it is constantly reset until the first mold bag 102 outside the guard plates 101 is fully in contact with the inner wall of the tunnel and is squeezed, so that the rotating shaft 105 is squeezed by the first mold bag 102 that is squeezed and deformed, so that the rotating shaft 105 is completely retracted to the inner wall of the guard plates 101;

[0067] When the rotating shaft 105 is continuously squeezed and rotated, the telescopic shaft 107 set at one end thereof will be continuously squeezed under the action of rotation, and the telescopic shaft 107 will squeeze the compression spring 108 and move along the first material transport groove 103 until the telescopic shaft 107 is completely rotated to the guard plate 101. At this time, the central channel of the telescopic shaft 107 is connected with the first material transport groove 103. At this time, the telescopic shaft 107 rebounds and passes through one end of the rotating shaft 105 under the action of the compression spring 108, extending to the inside thereof, thereby limiting the rotating shaft 105 until the guard plate 101 is placed. At this time, the clamping device is released and the squeezing block 111 is pushed. The squeezing block 111 When moving toward the inner wall of the guard plate 101, it moves toward the inside of the connecting tube 110 through the side groove 113 at its bottom and squeezes the spring sheet 114. At this time, the squeezing block 111 squeezes the spring sheet 114 and, under the action of the reaction force, pushes the connecting tube 110 to move until the limiting shaft 112 is engaged with the clamping plate 115, thereby limiting the connecting tube 110 and the squeezing block 111. At this time, the squeezing block 111 is in full contact with the connecting tube 110 through the side groove 113, thereby sealing the connecting tube 110. At this time, the connecting tube 110 is fully moved and extends through the other end of the rotating shaft 105 to the inside thereof, thereby sealing and penetrating the rotating shaft 105.

[0068] At this time, two sets of guard plates 101 are taken out again, and the above steps are repeated to splice them at the two ends of the guard plates 101, and at the same time, the first material transport troughs 103 symmetrically opened inside the three sets of guard plates 101 are connected;

[0069] Finally, take out the top plate 201, clamp the feed pipe 203 symmetrically arranged on the inner side of the top plate 201 through the clamping device, and place it on the top of the inner side of the tunnel, so that the two sides of the top plate 201 are spliced ​​with the two groups of guard plates 101, and ensure that the first material transport trough 103 is connected to the second material transport trough 204. At this time, concrete is pressurized and poured into the interior of the second material transport trough 204 through the feed pipe 203, and concrete is pressurized and poured into the interior of the second mold bag 202 through the second discharge trough 205. At the same time, the concrete inside the second discharge trough 205 is pressurized and poured into the interior of the first mold bag 102 through the first material transport trough 103 connected to it and the first discharge trough 104 that penetrates the first material transport trough 103, until the interior of the first mold bag 102 and the second mold bag 202 as well as the first material transport trough 103 and the second material transport trough 204 are fully filled with concrete. At this point, a set of support structures is spliced.
