Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to a construction method for a quickly installed communication tower base and a quickly constructed communication base station. Background Art

[0002] Communication towers are mainly affected by wind loads, so the design of towers and foundations should mainly consider the anti-overturning under wind loads. Conventional communication towers have two anti-overturning design ideas: guyed type and self-supporting type. The foundation scheme of self-supporting towers is generally divided into two categories, one is cast-in-place concrete foundation, and the other is prefabricated counterweight foundation.

[0003] The guyed tower uses steel hinges distributed in three or four directions on the plane to fix the tower body and play a role in anti-overturning. Because the guyed wires are limited in angle, they generally occupy a large area. At the same time, the guyed wires are flexible cable structures, and prestressing needs to be applied during construction. After long-term use, they are prone to loosening, rusting and other problems. Therefore, the guyed tower is more difficult to coordinate the site, and more frequent maintenance and replacement of the guyed steel hinges are required during later use.

[0004] The cast-in-place concrete foundation is constructed by pouring a cast-in-place concrete foundation after excavating a foundation pit and then backfilling. This form of foundation is safe and reliable, but it requires a long concrete curing period. The upper tower body can only be installed after the concrete has reached the required strength. The construction period is particularly long, generally taking more than 1 month, and in many cases it cannot meet customers' delivery needs. In addition, the cast-in-place concrete foundation is limited by temperature conditions during winter construction. When the temperature is too low, the hydration reaction and strength of the concrete cannot be guaranteed. At low temperatures, the internal free water freezes and expands in volume, causing damage to the internal structure of the concrete, reducing the ultimate strength and durability, and resulting in unqualified foundation quality. In addition, the cast-in-place concrete foundation requires a large amount of foundation materials to be transported from other places or manually transported to the site location, which brings great difficulties to the construction of sites in mountainous, remote, border, plateau and other areas with inconvenient transportation conditions. In winter in cold areas, the temperature is too low to meet the concrete curing conditions, so basically the work has to be stopped.

[0005] Prefabricated counterweight foundation is a concrete foundation that is cast and cured in the factory in advance. When construction is underway, the blocks are transported to the site for installation by crane, and the blocks are connected into an integral foundation form through some connectors of the steel structure. This type of foundation solves the construction period and winter construction problems to a certain extent, but it requires good traffic and site conditions for the crane to pass and operate, and it takes a long time in advance to clarify the demand and prepare the factory. In many cases, mountainous, remote, border, plateau and other areas do not have the conditions for crane access, and the distance for manual secondary transportation is long, making it impossible to carry out manual transportation of large items.

[0006] Therefore, the existing communication tower infrastructure and construction methods cannot adapt to the rapid construction in mountainous, remote, border, plateau and other areas with inconvenient transportation. The sites in such areas are far away from towns, with poor transportation conditions and long secondary transportation distances. A large amount of materials required for the foundation need to be manually transported to the site, and the manual secondary transportation fee accounts for a large part of the construction cost. At the same time, since the cast-in-place concrete foundation requires a long time of maintenance to reach the required strength, the overall construction period is too long, generally requiring more than 30 days. The conventional method of building a station requires multiple types of work to go to the station for construction multiple times, and the labor and road tolls occupy too high a construction cost. At the same time, the inconvenient transportation conditions make it difficult for even manual entry, and it is even more inconvenient to use conventional prefabricated counterweight foundations that require the use of cranes. Therefore, there is an urgent need for a construction method that requires less material to be transported, can go to the station at one time, and can quickly complete all work content within a few days to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a communication tower base that can be quickly installed. It has a novel structure, is easy to operate, and has few constituent materials. It uses the weight of natural soil that is locally sourced to resist overturning, greatly reducing the materials used for the foundation. The bottom only needs to be poured with a minimum of 100 mm thick concrete, with a total volume of 1.35 cubic meters. The foundation material is only 1 / 10 of the foundation of a conventional small communication tower. After the bottom concrete strength reaches 1.2 MPa, the backfill construction of the upper covering soil can be carried out. If the construction period needs to be further compressed, a layer of isolation pieces can be laid on the surface of the bottom concrete after the initial setting, and the backfill construction of the upper covering soil can be carried out. The installation of the base and the backfilling of the covering soil can be completed within one day. The structure has a high degree of modularization, the upper tower structure can be serialized, all the components are simplified and lightweight, easy to install and manually transported for the second time, and can be transported for the second time by drones and other means. It is particularly suitable for the rapid construction of communication base stations in areas with inconvenient transportation. Under normal circumstances, the construction goal of overall completion in about 2 days can be achieved, and it can provide safe, reliable and fast solutions for universal service projects, network blind spot filling projects in difficult areas, border defense and other communication base station construction projects.

[0028] First embodiment This embodiment provides a communication tower base 100 for quick installation. Figure 1 and Figure 2 As shown, it includes an outer frame 111 formed by splicing a plurality of identical side trusses 110 end to end. According to the number of side trusses, the outer frame 111 is formed as follows Figure 1 The regular triangle, regular quadrilateral, regular pentagon, regular hexagon, etc. are shown. In this embodiment, a regular quadrilateral is taken as an example.

[0029] like Figure 2 and Figure 3As shown, one corner of the outer frame 111 is the first fixed angle 112, and the first fixed angle 112 can be connected to the first vertical height-increasing rod 113 through the top flange, and the top of the first vertical height-increasing rod 113 can be connected to the main rod 210 of the tower mast 200 through the flange. The two corners adjacent to the first fixed angle 112 are the second fixed angles 114, and the second fixed angle 114 is connected to the second vertical height-increasing rod 115 through the top flange, and the top of the second vertical height-increasing rod 115 can be connected to the diagonal brace 220 of the tower mast 200 through the flange. The communication tower is mainly subjected to wind loads, and the design of the tower and foundation should mainly consider the anti-overturning ability under wind loads. Since the communication tower base 100 uses backfill soil as a counterweight, the strength of its anti-overturning ability is directly related to the weight of the backfill soil. Therefore, when installing the communication tower base 100, it is necessary to determine the excavation depth of the foundation pit 300 according to the amount of backfill soil, and the length of the first vertical heightening rod 113 and the second vertical heightening rod 115 is determined according to the thickness of the backfill soil, so that the top of the first vertical heightening rod 113 and the second vertical heightening rod 115 can be exposed from the soil layer, which is convenient for connection and installation with the tower mast 200. Among them, the first vertical heightening rod 113 and the second vertical heightening rod 115 can be made of long rods of the same size, which is convenient for unified processing. The first and second here only represent the distinction in position. In addition, the connection between the first fixed angle 112, the second fixed angle 114 and the first vertical heightening rod 113, the second vertical heightening rod 115 adopts a universal standard connection, and the position can be exchanged arbitrarily, which is convenient for rapid installation on site.

[0030] In addition, flanges are provided at the tops of the four corners of the outer frame 111, which can be connected to the first vertical height-increasing rod 113 and the second vertical height-increasing rod 115. Through such a setting, there is no requirement for the orientation of the outer frame 111 during installation, and it is also more convenient to perform unified processing.

[0031] Furthermore, if Figure 3 and Figure 4 As shown, the midpoint of the side frame truss 110 forms a middle fixed point 116 by connecting the node plate, and the upper end of each second vertical heightening rod 115 is connected to two adjacent middle fixed points 116 through a heightening rod diagonal brace 117. Since the top end of the second vertical heightening rod 115 is used to connect with the diagonal brace 220 of the tower mast 200, it is subject to lateral tension in addition to the gravity of the tower mast 200. Therefore, by providing two heightening rod diagonal braces 117, the diagonal support of the second vertical heightening rod 115 can be strengthened to prevent the second vertical heightening rod 115 from tilting and deforming. In contrast, the top end of the first vertical heightening rod 113 is used to connect with the main rod 210 of the tower mast 200, and the two are in a straight line. The second vertical rod is mainly subject to the gravity of the tower mast 200, so there is no need to add additional heightening rod diagonal braces 117.

[0032] Each side truss 110 is composed of two sub-trusses 118 of equal length, and the joint of the two sub-trusses 118 is the middle fixing point 116. This design can, on the one hand, disassemble the side truss 110 into smaller units, making it easier to transport; on the other hand, the joint of the two sub-trusses 118 coincides with the fixing point of the heightening rod diagonal brace 117, so only one connection structure needs to be designed, and this connection structure is universal, and can be adapted even if the length of the sub-truss 118 needs to be adjusted.

[0033] like Figure 1 and Figure 2 As shown, the communication tower base 100 also includes a plurality of first intermediate trusses 120, each of which connects the midpoints of two adjacent side trusses 110 through a connecting node plate, and the plurality of first intermediate trusses 120 form an inner frame 121. In addition, the communication tower base 100 also includes a plurality of second intermediate trusses 130, each of which connects the middle fixed point 116 with a connecting node plate set at the geometric center of the outer frame 111, and the plurality of second intermediate trusses 130 form a radial structure with the connecting node plate as the core. The first intermediate truss 120 and the plurality of second intermediate trusses 130 can both reinforce the outer frame, and the plurality of first intermediate trusses 120 and the plurality of second intermediate trusses 130 divide the inner part of the outer frame 111 into a plurality of triangular structures, and the triangle has stability, which greatly enhances the overall strength.

[0034] like Figure 2 and Figure 5 As shown, the side frame truss 110, the first middle frame truss 120, and the second middle frame truss 130 are all composed of two angle steels as the upper chord 1101 and the lower chord 1102, and then the angle steel is used as the middle diagonal web 1103 to connect the upper chord 1101 and the lower chord 1102, and welded into an integral component. Angle steel not only has better strength, but also is cheap and easy to obtain, which can reduce material costs. At the same time, the structure is not only lightweight, the weight of a single piece can be controlled within 15kg, so as to meet the load requirements of drone hoisting; and it is modular, with the sub-truss 118, the first middle frame truss 120, and the second middle frame truss 130 as the smallest unit, and various connection node plate structures are used to achieve the purpose of rapid installation, which provides excellent convenience for the transportation and secondary handling of components.

[0035] Furthermore, a plurality of U-shaped grooves 1104 are arranged at intervals on the upper surface of the lower chord 1102. The U-shaped grooves 1104 can be used to fix steel bars, and the steel bars are used to form a staggered network between the side trusses 110, and then the strength of the concrete layer 310 is increased after the concrete is poured. Figure 5As shown, the four corners of the outer frame 111 all form extensions 1111 downward, and the extensions 1111 can ensure that there is a distance of 50 mm between the lower chord 1102 of the outer frame 111 and the bottom surface of the foundation pit during installation, so that the concrete pouring at the bottom can pour the underlying cushion layer at one time and completely wrap the lower chord 1102 in the concrete to improve the overall strength.

[0036] Second embodiment This embodiment provides a construction method for quickly constructing a communication base station, which uses the communication tower base 100 of the first embodiment. Figure 6 As shown, including: S1. Dig a 300m foundation pit at the construction site.

[0037] Furthermore, the depth of the foundation pit 300 is calculated based on the actual conditions of the construction site, such as wind intensity, soil conditions, area of ​​the construction area and other factors, and a communication tower base 100 of appropriate size is selected. The foundation pit 300 is arranged as an inverted step as a whole, and the length and width of the bottom are slightly larger than the length and width of the outer frame 111.

[0038] S2. The communication tower base 100 is placed in the foundation pit 300 , and concrete is poured to submerge the lower half of the communication tower base 100 to form a concrete layer 310 .

[0039] Furthermore, the distance between the surface of the concrete layer 310 and the bottom surface of the communication tower base 100 (ie, the lower chord 1102) is not less than 100 mm. The lower chords 1102 of the side trusses 110, the first intermediate trusses 120, and the second intermediate trusses 130 need to be completely submerged.

[0040] In addition, in step S2, bidirectional steel bars are first arranged in the outer frame 111, and the bidirectional steel bars form a mesh structure between the side trusses 110; then concrete is poured to form a concrete layer 310. A plurality of U-shaped grooves 1104 are arranged at intervals on the upper surface of the lower chord 1102. Steel bars can be placed in the U-shaped grooves 1104 to fix the relative positions between the steel bars.

[0041] S3. After the concrete is finally set and the strength reaches about 1.2 MPa, spacers are laid on the concrete layer 310 , the original soil is backfilled to cover the spacers, and the foundation pit 300 is filled to form an original soil backfill layer 320 .

[0042] Among them, the isolation piece can be a wooden board, a plastic board, a plastic sheet, etc. In the traditional construction method, it is necessary to wait until the concrete is completely solidified and reaches the strength required by the design before the upper tower body can be installed. In the construction method of the present invention, the concrete layer 310 fixes the multiple side trusses 110 on the one hand, and constitutes the base of the outer frame 111 on the other hand, and forms a box-like structure together with the communication tower base 100, thereby supporting the soil above and transmitting the gravity of the soil to the communication tower base 100. The backfill soil above the concrete layer 310 actually plays the role of counterweight. The concrete layer only needs to act as a simple tray to support the soil above without leaking. Therefore, in the present invention, it is not necessary to wait until the concrete is solidified before the original soil backfill operation can be carried out, and the isolation piece can play a role of buffering and dispersing stress during the backfilling process, and keep the shape of the initial setting concrete layer 310 stable. Compared with the traditional method, the construction method of the present invention has a shorter construction period, greatly reduces the amount of concrete, and saves material costs and labor costs for transporting concrete.

[0043] In summary, an embodiment of the present invention provides a quickly installed communication tower base 100, which utilizes an outer frame 111 formed by splicing a plurality of identical side frame trusses 110 end to end, and a first heightening rod and a second heightening rod are arranged at the corners of the outer frame 111, which are respectively used to connect the main pole 210 and the diagonal brace 220 of the communication tower mast 200. The communication tower base 100 has the advantages of being lightweight, modular, and can be quickly installed. In addition, an embodiment of the present invention also provides a construction method for quickly constructing a communication base station, which uses the communication tower base 100, pours a small amount of concrete to form the base of the outer frame 111, and backfills the soil for compaction and fixation. On the one hand, the concrete layer 310 fixes the plurality of side frame trusses 110, and on the other hand, the base of the outer frame 111 supports the soil above, and transmits the gravity of the soil to the communication tower base 100, thereby playing a role in fixing and resisting lodging of the entire communication tower. This construction method occupies a small area, has a short construction period and low labor costs, and is better suited for the construction of communication base stations in areas with inconvenient transportation.
