DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0036] In the related technology, the guide trough diverts the energy (heat) generated during rocket launch. At present, the guide trough of the launch pad is mainly constructed by cast-in-place method, specifically, the reinforced concrete base 420, the reserved steel bars 422, and the ablation-resistant concrete 122 are cast as a whole. There are mainly the following problems: (1) The construction period is relatively long. The ablation-resistant concrete 122 can only be constructed after the base reinforced concrete reaches a certain strength. The later poured ablation-resistant concrete 122 also needs to solidify and harden and meet the strength requirements before it can be put into use. It can be understood that the diversion trough is cast in layers to form the ablation-resistant concrete 122 layers and the base reinforced concrete, which cannot be disassembled from each other. (2) The reinforced concrete base 420 and the ablation-resistant concrete 122 layers of the side walls, curved walls and other parts need to be supported by secondary formwork and poured separately, which greatly increases the construction cost and also increases the construction period; (3) When the 122 layers of ablation-resistant concrete are damaged after repeated use, it is necessary to repair the grooves, which is labor-intensive and takes a long time to reuse after repair; (4) Multiple pouring construction will cause more site interference factors to the construction site, reduce labor productivity, and increase environmental pollution such as dust, while also generating more construction waste.

[0037] Combine the following Figure 1-Figure 10 The present invention describes the ablation-resistant prefabricated components of the guide trough, the composition and structure of the guide trough, and the construction method of the guide trough. In this embodiment, the guide trough includes a bottom wall, a side wall, and a beam wall spaced above the bottom wall. The ablation-resistant prefabricated components are used to contact the airflow generated when the rocket is launched.

[0038] It should be noted that, in an embodiment of the present invention, the above-mentioned guide trough is applied to a rocket launch pad guide trough. Of course, in some other embodiments, the above-mentioned guide trough can also be applied to other fields, for example, to drainage and diversion buildings, etc.

[0039] It is understandable that, referring to Figures 1 to 4 The present invention provides an ablation-resistant prefabricated component of a guide trough, including a prefabricated body 100 and a connecting structure 200. The prefabricated body 100 is provided with an installation channel 110. The connecting structure 200 is arranged in the installation channel 110 of the prefabricated body 100. The connecting structure 200 is used to detachably install the prefabricated body 100 in a preset area.

[0040] It should be noted that, in this embodiment, the ablation-resistant concrete 122 is poured in advance to form the prefabricated body 100 , and a mounting channel 110 is left for the assembly of the connection structure 200 , thereby forming an ablation-resistant prefabricated component.

[0041] It should also be noted that, in this embodiment, the above-mentioned preset area is a position for forming a guide groove. Figures 4 to 9 In the preset area, a reinforced concrete base 400 and a mounting structure 410 are provided in the preset area. The mounting structure 410 is connected to the reinforced concrete base 400. The connecting structure 200 cooperates with the mounting structure 410 and is detachably connected. After completion, other corresponding construction steps can be carried out.

[0042] The ablation-resistant prefabricated component of the guide trough provided by the present invention can be detachably installed in a preset area by means of a connecting structure 200, so that the fire-resistant layer of the guide trough is replaceable and easy to disassemble and assemble, and can be disassembled as needed, thereby shortening the construction period, reducing the construction cost, and reducing the repair workload, thereby improving the quality and safety of the project.

[0043] It is understandable that, referring to Figures 5 to 10 In an embodiment of the present invention, the connection structure 200 includes a connection member 210, which is disposed in the installation channel 110 and is movably connected to the prefabricated body 100. The connection member 210 can move relative to the installation channel 110 to be installed and connected with a preset area.

[0044] With the above structure, the design of the connector 210 not only makes installation easy, but also makes disassembly of the prefabricated body 100 simple, thus providing convenience for future maintenance or replacement.

[0045] Specifically, refer to Figure 3 and Figure 6 In the embodiment of the present invention, the connecting member 210 is a connecting bolt, which has a simple structure and low cost. The head shape of the connecting bolt is a large flat head hexagon socket.

[0046] It is understandable that, referring to Figure 2 , Figure 3 and Figure 6 In an embodiment of the present invention, the connection structure 200 further includes a limiter 220, which is disposed in the mounting hole 110 and connected to the prefabricated body 100 to limit the relative positions of the connection member 210 and the prefabricated body 100 and to preliminarily position the connection member 210.

[0047] It should be noted that, refer to Figure 2 , Figure 3 and Figure 6 In this embodiment, the above-mentioned limit member 220 is a first threaded sleeve connected to the connecting bolt. The installation channel 110 includes an installation channel 111 reserved during the casting process of the prefabricated body 100, a blocking hole 112 located at the upper end of the installation channel 111, and a first sleeve connecting hole 113 located at the lower end of the installation channel 111. The connecting bolt is inserted into the installation channel 111 and threadedly connected with the first threaded sleeve. The blocking hole 112 is adapted to the connecting bolt, so as to limit the movement of the connecting bolt along the thickness direction of the prefabricated body 100 and improve the assembly stability.

[0048] Of course, in some other embodiments, the above-mentioned connecting member 210 can also be a pin shaft, etc., which is not limited here. Of course, in some embodiments, the above-mentioned limiting member 220 can also be a retaining ring, a bayonet, etc., which can limit the connecting member 210 from being separated from the prefabricated body 100 when not operated, which is not limited here.

[0049] It should be noted that, in the embodiment of the present invention, the blocking hole 112 is adapted to the connecting bolt. Of course, the connecting bolt may also be in other shapes, which is not limited here.

[0050] It is understandable that during the construction process, the first threaded sleeve is embedded in the casting process of the prefabricated body 100, and when the connector 210 is assembled with the prefabricated body 100, the connector 210 passes through the installation channel 111 and is screwed and fixedly connected with the stopper 220, i.e., the first threaded sleeve. Of course, in some embodiments, the stopper 220 may also be a retaining ring, a bayonet, etc., which can limit the connector 210 from being separated from the prefabricated body 100 when not operated, and this is not limited here.

[0051] It should be noted that, refer to Figure 5 , Figure 6 and Fig. 9In this embodiment, the ablation-resistant prefabricated component can be hoisted to the preset area by hoisting. Specifically, the connecting member 210, i.e., the connecting bolt, can be connected with an installation ring to perform temporary hoisting operations to install and disassemble the ablation-resistant prefabricated component. Of course, when the prefabricated body 100 is cast, a quick-release threaded sleeve 150 can also be pre-embedded, so that the prefabricated body 100 can be used for wall sidewall construction for easy disassembly and assembly.

[0052] It is understandable that, referring to Figure 5 , Figure 6 , Fig. 9 and Fig.10 In an embodiment of the present invention, the prefabricated body 100 is provided with a first blocking structure filled between the outer wall of the connecting structure 200 and the inner wall of the mounting channel 110 to limit the movement of the connecting structure 200. It can be understood that the first blocking structure can limit the movement of the connecting member 210 and the limiting member 220, and the mounting channel 110 can also be sealed by the first blocking structure to improve the airtightness.

[0053] Specifically, refer to Figure 5 , Figure 6 , Fig. 9 and Fig.10 In this embodiment, the first blocking structure includes a flexible fireproof material blocking layer 310 and a first refractory material blocking layer 320. It can be understood that a flexible fireproof material is installed in the hexagonal recess of the head of the connecting bolt to form a flexible fireproof material blocking layer 310; and then a refractory material blocking material is poured into the blocking hole 112 to form a first refractory material blocking layer 320 to block the blocking hole 112. Of course, in some embodiments, a flexible fireproof material may also be provided in the installation channel 111, which is not limited here.

[0054] It is understood that in the embodiment of the present invention, at least one of a shear key groove and a rough surface is provided on the inner wall of the installation channel 110. Specifically, a shear key groove or a rough groove surface is formed on the side wall of the plugging hole 112, or a shear key groove and a rough groove surface are formed on the side wall of the plugging hole 112, which can increase the shear resistance of the cross section and improve stability.

[0055] It is understandable that, referring to Figure 2 , Figure 3 and Figure 8 In the embodiment of the present invention, the prefabricated body 100 includes an integrally formed ablation-resistant concrete body 120 and a reinforcement structure 130, wherein the reinforcement structure 130 is disposed inside the ablation-resistant concrete body 120; wherein the reinforcement structure 130 is disposed around the mounting hole 110. Through the above arrangement, the reinforcement structure 130 can improve the structural strength at the mounting hole 110, and facilitate the assembly of the connection structure 200.

[0056] It should be noted that, in this embodiment, the reinforcing structure 130 is a reinforcing rib arranged around the mounting hole 110, that is, the reinforcing rib surrounds the connecting piece 210 (connecting bolt). Of course, in some embodiments, the reinforcing structure 130 can also be a reinforcing plate, which is not limited here.

[0057] It should also be noted that, referring to Figure 2 , Figure 3 and Figure 8 In this embodiment, the ablation-resistant concrete body 120 is constructed by pouring a steel mesh 121 and ablation-resistant concrete 122, and the steel mesh 121 can avoid the installation channel 110. In this embodiment, the steel mesh 121 is set as a double layer. Of course, it can also be set as a single-layer steel mesh 121, a three-layer steel mesh 121, etc., which is not limited here.

[0058] It is understandable that, referring to Figures 1 to 10 In the embodiment of the present invention, the composition structure of the guide trough includes the ablation-resistant prefabricated components of the guide trough and a reinforced concrete base 400. The reinforced concrete base 400 is provided with a mounting structure 410, and the connection structure 200 cooperates with the mounting structure 410 and is detachably connected.

[0059] Through the above structure, the connection structure 200 and the mounting structure 410 are matched and detachably connected, so that the ablation-resistant prefabricated components of the launch pad guide trough and the reinforced concrete matrix 400 structural layer are connected by dry node technology, and a series of assembled ablation-resistant precast concrete parts are developed to form an assembled ablation-resistant precast concrete dry connection technology that is replaceable, easy to disassemble, safe and reliable for the fire-resistant layer of the rocket launch pad guide trough, shorten the construction period of chiseling and replacing the fire-resistant layer of the rocket launch pad guide trough, reduce construction costs, reduce environmental pollution, reduce site interference, save water, electricity, materials and other resources and energy, and improve project quality and safety.

[0060] Specifically, refer to Figure 4 In this embodiment, the mounting structure 410 is a second threaded sleeve, which is threadedly connected to the connector 210 and the connecting bolt through the second threaded sleeve. It can be understood that the first threaded sleeve and the second threaded sleeve are aligned by hoisting, and the connecting bolt is threadedly connected to the second bolt sleeve by screwing the connecting bolt. It can be understood that the above connection method is a dry connection.

[0061] It is understandable that, referring to Figure 4 In the embodiment of the present invention, the reinforced concrete base 400 includes a reinforced concrete base 420 and a positioning plate 430, and the positioning plate 430 is arranged on a side facing the prefabricated body 100; wherein the positioning plate 430 is provided with a positioning portion 431 for positioning and cooperating with the mounting structure 410. Through the above, the mounting structure 410 can be pre-positioned.

[0062] It should be noted that in this embodiment, the reinforced concrete base 420 is formed by pouring the base concrete 421 and cooperating with the reserved steel bars 422, and when the base concrete 421 is poured, it can be integrally cast with the positioning plate 430 and the mounting structure 410 to fix the position and form the reinforced concrete matrix 400; the positioning plate 430 is a steel plate with a positioning portion 431, and of course it can also be other plates, which are not limited here. Through the above structure, a "pre-installed" effect is formed to ensure the accurate positioning of the embedded part of the base concrete 421, namely the second threaded sleeve, and improve the subsequent installation efficiency and installation accuracy of the ablation-resistant prefabricated components.

[0063] It should also be noted that, referring to Figure 4 In this embodiment, the reinforced concrete base 400 is reserved with a second sleeve connecting hole 423, and the second threaded sleeve is reliably fixed in the second sleeve connecting hole 423; the reserved steel bars 422 are arranged corresponding to the second threaded sleeve, thereby improving the structural strength of the reinforced concrete base 400 and the stability of the second threaded sleeve.

[0064] It is understandable that, referring to Figure 1 , Figures 7 to 9 In the embodiment of the present invention, the number of ablation-resistant prefabricated components of the guide groove is multiple, and a second plugging structure is provided between the opposite end side walls of adjacent prefabricated bodies 100. Specifically, in the present embodiment, the second plugging structure is a second refractory material plugging layer 330, which is formed by pouring refractory material plugging material in the gap between adjacent prefabricated bodies 100 to improve airtightness and integrity.

[0065] It should be noted that, refer to Figure 1 and Figure 2 In the embodiment of the present invention, the circumferential side surface of the prefabricated body 100 is configured as an inclined surface 140, and the working surface of the prefabricated body 100 in the up-down direction, i.e., the thickness direction, is a plane. Therefore, the inclined surface 140 is inclined to the plane, and therefore, the opposite end surfaces of adjacent prefabricated bodies 100 are configured to have an angle with the working surface of the prefabricated body 100. The gaps between adjacent prefabricated bodies 100 are sealed by the second blocking structure to improve airtightness and integrity.

[0066] In this embodiment, since the opposite end sides of the adjacent prefabricated bodies 100 are arranged in an inclined manner to form an oblique gap, the stability of the assembly between the adjacent prefabricated bodies 100 is increased, which is convenient for production and manufacturing. Figure 8, arrow a points to the direction of airflow, and there is an angle between the direction of airflow and the oblique gaps on the opposite side surfaces of the adjacent prefabricated bodies 100. When the airflow acts on the working surface of the prefabricated bodies 100, the oblique gaps between the adjacent prefabricated bodies 100 and the second blocking structure improve the connection performance of the adjacent prefabricated bodies 100, which is conducive to preventing the prefabricated bodies 100 from being lifted by the airflow and improving stability. Of course, the opposite side surfaces of the adjacent prefabricated bodies 100 can also be curved, which is not limited here.

[0067] Reference Figure 4 In the embodiment of the present invention, one end of the mounting structure 410 protrudes from the side of the reinforced concrete base 400 facing the prefabricated body 100, and the protruding portion of the mounting structure 410 is used for plugging and matching with the installation channel 110. With the above structure, the mounting structure 410, i.e., the second threaded sleeve, is protrudingly arranged and can be plugged and matched with the installation channel 110 to achieve the preliminary positioning of the ablation-resistant prefabricated component and improve the installation efficiency. In addition, a shear groove can be formed after installation to improve the shear resistance between the ablation-resistant prefabricated component and the reinforced concrete base 400, and prevent the ablation-resistant prefabricated component from sliding horizontally.

[0068] It should be noted that, in the embodiment of the present invention, the positioning portion 431 is a positioning hole, and the positioning hole is inserted and positioned with the protruding portion of the second threaded sleeve. Of course, in some embodiments, the positioning portion 431 can also be a clamping structure that is clamped with the second threaded sleeve, which is not limited here; the second threaded sleeve protrudes 10mm to 20mm from the surface of the reinforced concrete base 400, and of course, it can be other values, which are not limited here.

[0069] It is understandable that, referring to Figures 1 to 10 In an embodiment of the present invention, a construction method of a guide trough uses the composition structure of the above-mentioned guide trough, and the construction method includes the following steps: based on the shape of the guide trough, determining the assembly parameters of the ablation-resistant prefabricated components and the reinforced concrete matrix 400, transporting the required materials to the construction area, and performing construction to form the guide trough, wherein the assembly parameters of the ablation-resistant prefabricated components include at least the assembly position and the number of assemblies.

[0070] Through the above method, the bottom wall, side wall and beam wall of the guide channel are constructed. Different ablation-resistant prefabricated components and reinforced concrete matrix 400 can be constructed according to the needs and the ablation-resistant prefabricated components can be replaced according to the positions.

[0071] It is understandable that, referring to Figure 5 In an embodiment of the present invention, the bottom wall construction method of the guide groove includes the following steps: Performing the forming construction of the reinforced concrete base 400 and the mounting structure 410; After the construction of the reinforced concrete base 400 and the mounting structure 410 is completed, the ablation-resistant prefabricated components are driven to align the mounting structure 410 and the connection structure 200, and the connection structure 200 is driven to cooperate with the mounting structure 410 and be detachably connected; After the connection structure 200 and the mounting structure 410 are connected, a plugging material is poured into the installation channel 110 and between a plurality of adjacent prefabricated bodies 100 .

[0072] Specifically, refer to Figure 5 After the construction of the reinforced concrete base 400 is completed, the second threaded sleeve pre-embedded in the reinforced concrete base 420 protrudes from the surface of the reinforced concrete base 400, and the large flat head hexagonal connecting bolt is screwed to the first threaded sleeve pre-embedded in the erosion-resistant prefabricated component as a lifting point, and the reserved first sleeve connecting hole 113, the second sleeve connecting hole 423 and the second pre-embedded threaded sleeve of the erosion-resistant prefabricated component are aligned, and the connecting bolt is continued to be screwed until it is connected with the second threaded sleeve, and the hexagonal recess of the head of the connecting bolt is sealed with an internal flexible fireproof material, and then the sealing hole 112 is sealed with a post-cast refractory material. The oblique gaps between the prefabricated bodies 100 of multiple erosion-resistant prefabricated components are sealed with post-cast refractory materials. Through the above construction method, the "preliminary positioning" of the erosion-resistant prefabricated components can be facilitated, the installation efficiency can be improved, the shear resistance of the cross section of the erosion-resistant prefabricated components and the base concrete 421 can be improved, and the horizontal slip of the erosion-resistant prefabricated components can be prevented.

[0073] It should be noted that, refer to Fig. 9 , plugging materials are poured in the installation channel 110 and between multiple adjacent prefabricated bodies 100. The wet connection can improve the integrity of the ablation-resistant prefabricated components. When removing and replacing, it is only necessary to chisel out the first refractory material plugging layer 320 of the sealing hole 112, the corresponding flexible fireproof material, and the second refractory material plugging layer 330 poured later in the oblique gap. After removal and replacement, the flexible fireproof material can be reused, reducing the cost of removal and replacement.

[0074] It can be understood that in this embodiment, the end face of the prefabricated body 100 is processed into a bevel, the end faces of adjacent prefabricated bodies 100 are inclined to form a staggered fit, and the connection between adjacent prefabricated bodies 100 is formed by pouring refractory materials to form a wet connection method, which can improve the integrity of the ablation-resistant prefabricated components and reduce the impact of the staggered laying of the ablation-resistant prefabricated components on dismantling and lifting.

[0075] It should be noted that the pre-embedded and reserved ablation-resistant prefabricated components are produced by the corresponding factories and do not need to be cast during the construction of the diversion trough; the size, quantity and material selection of the above-mentioned ablation-resistant prefabricated components can be set accordingly according to needs, and the selection of suitable ablation-resistant materials depends on the working environment, temperature requirements, chemical properties and required wear resistance, corrosion resistance and other properties of the diversion trough. When selecting refractory materials, these factors need to be comprehensively considered to ensure the stability and performance of the diversion trough.

[0076] It is understandable that, referring to Figure 6 and Figure 7 In an embodiment of the present invention, the construction method of the side wall of the guide groove includes the following steps: Tie the wall reinforcement cage to the vertical position of the preset area. After the wall reinforcement cage is tied, embed the installation structure into the wall reinforcement. Spray a mold release agent on the side of the prefabricated body 100 of the ablation-resistant prefabricated component facing the wall reinforcement, match the connection structure 200 with the installation structure and detachably connect them, and support the prefabricated body 100 on the side facing away from the wall reinforcement; Cast the side wall concrete to form a reinforced concrete matrix 400. After casting is completed until the preset strength is met, remove the side formwork support and reconnect the connector 210. A plugging material is poured in the installation channel 110 and between a plurality of adjacent prefabricated bodies 100 .

[0077] Specifically, refer to Figure 6 and Figure 7 After the wall reinforcement cage is tied, the second threaded sleeve is embedded in the reserved reinforcement 422 concrete, and the release agent is sprayed on the inner side of the prefabricated body 100 of the ablation-resistant prefabricated component of the wall side wall to form a release agent layer 500. After it is hoisted to the designated position, a side mold cross keel 160 is provided on the outer side of the prefabricated body 100 of the ablation-resistant prefabricated component. A large flat head hexagon socket connecting bolt is used to pass through the side mold cross keel 160 and screwed to connect with the embedded second threaded sleeve, and then fixed by an oblique support as the wall side wall. After the erosion-resistant prefabricated components are assembled, the side wall concrete is poured to form a reinforced concrete matrix 400. After the side wall concrete meets the strength requirements, the side formwork support is removed, and the connecting bolts are screwed to the second threaded sleeve of the reinforced concrete matrix 400 to be tightened. The hexagonal recess of the head of the connecting bolt is sealed with an internal flexible fireproof material, and then the sealing hole 112 is sealed with a post-cast refractory material. The oblique gaps between the prefabricated bodies 100 of the multiple erosion-resistant prefabricated components are sealed with post-cast refractory materials. Through the above construction method, the "preliminary positioning" of the erosion-resistant prefabricated components can be facilitated, the installation efficiency can be improved, the shear resistance of the interface between the erosion-resistant prefabricated components and the base concrete 421 can be improved, and the vertical slip of the erosion-resistant prefabricated components can be prevented.

[0078] It should be noted that when forming the wall side wall of the guide groove, the side formwork cross keel 160 can be connected to the quick-release threaded sleeve 150 of the prefabricated body 100 through the connecting piece 210 of the connecting structure 200. Some threaded sleeves are reserved inside both the ablation-resistant prefabricated component of the wall side wall and the unpoured concrete area. A connection system integrating the side formwork cross keel 160, the ablation-resistant prefabricated component and the base wall steel cage can be formed, which is convenient for pouring concrete and facilitating the installation of the ablation-resistant prefabricated component as a side panel, while taking into account the lifting of the embedded lifting points.

[0079] It should also be noted that, referring to Figure 6 and Figure 7 The quick-release threaded sleeve 150, the first threaded sleeve, the connecting bolts and the temporary long screw tool can be used for temporary fastening of the steel cage composed of the reserved steel bars 422 of the erosion-resistant prefabricated components, the reinforced concrete base 420 and the side formwork cross keel 160, so as to prevent the erosion-resistant prefabricated components from tipping inward or outward during the construction of the wall side wall, thereby forming an integrated connection system of the side formwork-the side plate of the erosion-resistant prefabricated component-the steel cage of the base wall; at the same time, the quick-release threaded sleeve 150 of the internal reserved part can be used for temporary lifting, avoiding the need for pre-embedded lifting parts for the lifting operation.

[0080] It can be understood that, in the embodiment of the present invention, the beam wall construction method of the guide groove includes the following steps: Supporting and installing the ablation-resistant prefabricated component at a certain height from the bottom wall of the guide trough; After the ablation-resistant prefabricated components are installed, the steel bars are tied, and the assembly structure 410 is matched with the connection structure 200 and detachably connected; A plugging material is poured in the installation channel 110 and between a plurality of adjacent prefabricated bodies 100 .

[0081] Specifically, the ablation-resistant prefabricated component at the bottom of the beam wall is installed first, and when the second threaded sleeve is reserved for steel bar binding, it is connected to the second threaded sleeve through the connecting bolts on the prefabricated body 100 as the beam wall, and then concrete is poured.

[0082] It should be noted that, refer to Figure 8 In the embodiment of the present invention, a staggered oblique gap is reserved between two adjacent prefabricated bodies 100, the oblique gap and the plugging hole 112 are plugged with refractory materials, and the hexagonal recess of the connecting bolt is plugged with a flexible fireproof material, so that the staggered paved erosion-resistant prefabricated components can be smoothly removed. Through the above method, the refractory plugging material in the plugging hole 112 cooperates with the flexible fireproof material to form a combination of wet connection and flexible connection, thereby improving the integrity of the erosion-resistant prefabricated components and enhancing the convenience of disassembly and replacement.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
