Description

Technical Field

[0001] The utility model relates to slope treatment, in particular to a temporary slope support system integrating retaining and protection, belonging to the technical field of slope treatment equipment. Background Art

[0002] In the expressway expansion project, in order to meet the need of road widening, the existing high slopes that have been in a relatively stable state have to face major renovations - that is, the existing support structures need to be removed, and comprehensive cross-section slope cutting operations need to be carried out. Moreover, during the slope cutting operation, rock fragmentation and excavation are also required. That is, with the official start of the secondary construction, the original stress balance state of the high slope begins to be broken, and its internal stress field then enters a stage of dynamic adjustment. It should be noted that during the critical period of slope stress field adjustment and remodeling, the stability of the slope becomes particularly vulnerable. At this time, if affected by adverse natural factors such as rainfall, the soil and gravel on the surface layer of the slope are extremely likely to reduce their shear strength due to water infiltration, and then slide or collapse along the slope surface under the action of gravity. Such slope instability phenomena not only seriously threaten the safety of the construction site, but may also directly interfere with the normal operation of the existing expressway, leading to a series of chain reactions such as traffic delays and increased accident risks, posing a major challenge to the safety of public travel and the smooth operation of the regional traffic network.

[0003] To address the above problems, when carrying out secondary excavation operations on current expressway slopes, it is generally necessary to take measures to build temporary retaining structures. The commonly used temporary retaining measures generally rely on the bent structure built by wooden boards. Its installation process is relatively cumbersome and requires a large amount of manpower and time; especially when facing high and steep rock slopes with complex geological conditions and limited construction space, its assembly and disassembly are extremely difficult, seriously hindering the progress of the construction. In addition, the existing bent structure is also difficult to effectively block the flying stones generated during slope excavation, and there is a situation where flying stones fall into the operating road surface and affect road safety. Furthermore, the existing temporary retaining system has obvious deficiencies in intelligent monitoring. Due to the lack of necessary monitoring equipment and means, it is difficult for construction personnel to timely and accurately master the stress state and deformation of the retaining structure, and thus unable to take targeted maintenance and reinforcement measures in a timely manner. This state of information deficiency undoubtedly increases the safety risks of highway slopes during excavation, which is not conducive to ensuring the long-term stable operation of the highway and the safe passage of passing vehicles. Content of the Utility Model

[0004] Aiming at the problems that existing temporary retaining structures are difficult to effectively prevent soil landslides and flying rocks from scattering, time-consuming and laborious to build, and lack of real-time monitoring mechanisms, the utility model provides a temporary slope support system with integrated retaining and protection. In view of the characteristics of existing slope renovation, through structural optimization, the active retaining and the passive protection net are coupled together to form a temporary retaining and protection system with an integrated retaining and protection structure. On the one hand, it can effectively prevent the landslide of slope soil and passively protect flying rocks at the same time. At the same time, the prefabricated structure design is adopted, which is convenient for erection and disassembly and can be recycled. On the other hand, cable traction reinforcement is added to further improve the support effect of the retaining and protection system and facilitate the installation of a tension sensor with real-time monitoring function, so as to realize the integration of retaining, protection and real-time monitoring, and truly ensure the safety of road operation.

[0005] To achieve the above technical objectives, the technical solutions adopted by the utility model are as follows:

[0008] Preferably, a vertical connection hole is opened on the top end surface of the retaining column, and internal threads are provided in the vertical connection hole. External threads are provided on the bottom end side wall of the protection net column, and the bottom end of the protection net column is installed in the vertical connection hole through the external threads and the internal threads.

[0009] Preferably, the slope temporary support system further includes a fixed cross beam. A vertical connection hole is opened on the top end surface of the retaining column, and a through horizontal connection hole is opened on the top end side wall of the retaining column, and the vertical connection hole and the horizontal connection hole are connected. A through connection hole with the same size and orientation as the horizontal connection hole is opened on the bottom end side wall of the protection net column. The bottom end of the protection net column is inserted into the vertical connection hole so that the horizontal connection hole and the through connection hole are connected. The fixed cross beam is located between any two adjacent retaining columns, and both ends of the fixed cross beam pass through the horizontal connection hole and the through connection hole at the top of the two retaining columns in sequence along the horizontal direction.

[0010] Preferably, the temporary slope support system further includes fixing blocks. The fixing blocks are provided at both ends of the fixing cross beam after it passes through the transverse connection holes and the through connection holes in sequence.

[0011] Preferably, the fixing block is a rectangular block structure. Through notches are formed on a pair of side walls of the fixing block. Through threaded holes communicating with the notches are formed on the other pair of side walls of the fixing block where no notches are provided. Through fixing threaded holes are formed on the side walls at both ends of the fixing cross beam after it passes through the transverse connection holes and the through connection holes in sequence. The fixing block is sleeved on the end of the fixing cross beam through the notches so that the through threaded holes communicate with the fixing threaded holes. The through threaded holes and the fixing threaded holes are connected by bolts.

[0012] Preferably, a plurality of baffle mounting grooves are formed from top to bottom on the opposite two side walls of any adjacent two retaining columns, and both ends of the baffle are respectively inserted into the baffle mounting grooves at the same height of the adjacent two retaining columns.

[0013] Preferably, a plurality of net retaining fasteners are arranged on the net retaining column from top to bottom. The protective net is installed between any adjacent two net retaining columns through the net retaining fasteners.

[0014] Preferably, the net retaining fastener is one or more of a metal nail, a metal ring, a metal hook, and a perforated metal sheet.

[0015] Preferably, a threaded column extending along its axis is provided on the net retaining column, a plurality of threaded collar rings are sleeved on the threaded column from top to bottom, and the net retaining fasteners are arranged on each threaded collar ring. The protective net is installed between any adjacent two threaded columns through the net retaining fasteners and the threaded collar rings, and the height of the protective net is adjusted by moving the threaded collar rings on the threaded column. Preferably, the threaded column is detachably connected to the net retaining column through a clamping member.

[0016] Preferably, one end of the steel cable is connected to the slope soil body through an anchor rod, and its other end passes through the tops of all the net retaining columns in sequence and is then connected to the slope soil body through an anchor rod. Preferably, pulleys are provided at the tops of the two outermost net retaining columns, and the steel cable is deflected through the pulleys. The tension sensor is arranged on the steel cable at the top of the net retaining column.

[0017] In the prior art, during the process of reconstructing and excavating an existing slope, it is generally necessary to set up retaining measures to prevent the slope from collapsing and affecting the operating road. Existing temporary retaining structures are usually simple scaffolding structures made of wooden boards. Not only is it difficult to ensure the retaining effect, but the construction process is relatively cumbersome, and it is unable to effectively intercept flying rocks generated during construction (flying rocks entering the operating road and posing potential safety hazards). At the same time, the later demolition of the retaining structure is difficult and it is basically impossible to be reused, easily causing waste of resources. To address this problem, the present utility model provides a temporary slope support system that combines retaining and protection functions. The lower part of the system is an active retaining structure composed of assembled retaining columns and retaining boards, which can effectively inhibit the collapse of the slope. The upper part of the system is a passive protection structure composed of assembled protection net columns and protection nets, which can effectively intercept flying rocks generated during construction. The lower active retaining structure provides support for the upper passive protection structure, expanding the protection range of the passive protection structure. In addition, steel cables are used to further strengthen the integrated active retaining structure and passive protection structure, improving the active and passive protection capabilities of the system. At the same time, it facilitates the installation of force sensors with real-time monitoring functions, thereby enhancing the real-time monitoring mechanism of the system and effectively evaluating and judging the actual situation of the current support system. It should be noted that the present utility model cleverly connects the originally scattered structural components into a closely connected whole, successfully enhancing the overall stiffness and stability of the structure. This integrated design not only improves the load-bearing capacity of the structure but also significantly enhances its ability to resist external loads and deformations, providing strong protection for the safety and stability of the slope. In addition, by adopting the design scheme of integral installation and disassembly, the convenience and efficiency of the construction process can be significantly improved. It not only simplifies the installation steps, reduces manual intervention, but also greatly shortens the construction period, thus effectively improving the overall project progress. At the same time, the integral design is also convenient for later maintenance and disassembly, bringing great convenience to the construction team.

[0018] In the present utility model, multiple retaining columns are arranged in rows along the bottom of the slope, and a standard baffle is installed between any two adjacent retaining columns through a prefabricated baffle installation groove, thus forming the bottom active retaining structure. It should be noted that the specific number of retaining columns is designed according to actual needs. Generally, the more the number of retaining columns and the smaller the distance between two adjacent retaining columns, the stronger the protection effect of the formed retaining structure. Among them, as the core component of the retaining structure, in order to improve its performance against external forces, the retaining column is generally made of a rigid material with a certain strength, such as a rectangular steel column. For the retaining board, it can be made of a rigid material or directly use a template, which is selected according to actual needs.

[0019] Furthermore, in order to further improve the speed and stability of the installation of the retaining column, vertical threaded holes are preset on the bottom end surface of the retaining column. At the same time, reinforcing nails are provided. The top end of the reinforcing nail is provided with a threaded section for quick connection with the vertical threaded hole. The bottom end of the reinforcing nail is generally a tapered structure that gradually tapers from top to bottom, so that it can be quickly anchored in the soil body. It should be noted that according to the actual situation of the slope soil body and the different system installation specifications, the length of the reinforcing nail can be long or short (both are standard designs, and the corresponding length can be directly selected according to needs), so as to effectively ensure the stability of the retaining column.

[0020] In the present utility model, a vertical connection hole for installing the protective retaining column is opened at the top end of the retaining column. The bottom end of the protective net column is detachably connected to the vertical connection hole, for example, by means of threaded connection or clamping (such as the cooperation of a fixed cross beam and a fixed clamping block) through a structure similar to a mortise and tenon structure. A standard protective net is installed between any two adjacent protective net columns through a protective net buckle, thereby forming an upper passive protection structure. By adopting a detachable assembled structure for the retaining column and the protective net column, combinations of active retaining structures and passive protection structures of any specifications can be realized, thereby improving the secondary utilization efficiency of the system structure components while increasing the applicable range and scenarios of the system.

[0021] Furthermore, a threaded column (i.e., an external thread is provided on the cylinder, and the external thread is an uninterrupted whole thread from top to bottom on the cylinder surface or is divided into multiple spaced threaded sections from top to bottom) is detachably installed on the protective net column along its axis through a clamping member (i.e., one end of the clamping member is fixed to the protective net column, and the other end has a clamping portion for clamping the threaded column. The clamping portion can be a round hole with threads, or can be an openable claw or clamping plate, or can be any existing device with a clamping and fixing function such as a clamp or a tie strap). The height of the threaded column is generally higher than the height of the protective net column, that is, the top end of the threaded column extends upward above the top end of the protective net column. A plurality of threaded sleeve rings (round tubes or nuts with internal threads) are sleeved on the threaded column, and a protective net buckle for connecting the protective net is installed on the side wall of the threaded sleeve ring. That is to say, by rotating the threaded sleeve ring, the height of the threaded sleeve ring on the threaded column can be adjusted, thereby realizing the adjustment of the height of the protective net buckle. That is to say, by adjusting the height of the protective net buckle and selecting an appropriate protective height of the protective net, it is beneficial to broaden the applicable scenarios and application range of the support system.

[0022] In the present utility model, one end of the steel cable is connected to the top of the protective net post, and the other end of the steel cable is connected to the soil mass of the slope (usually fixed in the soil mass of the slope through an anchor rod). The steel cable can strengthen the pulling of the integrated active retaining structure and passive protection structure, further improving the active retaining and passive protection effects of the active retaining structure and passive protection structure. In addition, a tension sensor is installed on the cable body of the steel cable (for example, Bengbu Gaoling CFBHPJ side pressure type tension sensor or any other existing mature sensor product with real-time tension monitoring and information transmission functions). The tension sensor monitors the stress condition of the steel cable in real time and transmits it to the monitoring terminal of the safety officer (such as a mobile device like a notebook or a mobile phone) in real time. The monitoring equipment (tension sensor, monitoring terminal, etc.) can collect and analyze the key data of the structure in real time. Once any abnormality or potential risk is detected, the system will immediately send out a warning signal, providing a timely and accurate decision-making basis for the construction team. The introduction of this intelligent monitoring and warning system not only improves the construction safety but also provides a strong guarantee for the long-term stable operation of the slope. It enables the construction team to master the integrity and safety status of the retaining structure in real time and accurately, and then timely discover and respond to the possible risks of system structure damage or failure.

[0023] Furthermore, in the present utility model, an independent steel cable and a supporting tension sensor can be provided between each protective net post or any one or more protective net posts and the soil mass of the slope. While significantly improving the active and passive protection effects, it can more accurately and conveniently master the stress condition of the system, thereby ensuring the safety of the system. For example, pulleys (which can play a role in deflecting the steel cable) are provided at the tops of the two outermost protective net posts. One end of the steel cable is connected to the soil mass of the slope through an anchor rod, and the other end passes through the tops of the two pulleys and all the intermediate protective net posts and is then connected to the soil mass of the slope through an anchor rod. Independent tension sensors are provided on the cable body between the two ends of the steel cable and the two pulleys, or the tension sensor is provided on the cable body between the two pulleys.

[0024] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0025] 1: The present utility model combines the active retaining structure and the passive protection structure using an assembly process. While improving the protection effect of the slope temporary support system, it greatly reduces the installation difficulty of the support system and improves the installation efficiency. Further, the adjustment of the height of the protective net buckle is realized by adding a threaded post and a threaded sleeve ring, expanding the applicable scenarios and scope of the support system; in addition, the support system also has good secondary recyclability, significantly reducing material consumption and production costs.

[0026] 2: By adding steel cables and tension sensors, the utility model significantly improves the retaining and protection effects of the support system. At the same time, it also greatly enhances the real-time monitoring ability of the support system, thereby facilitating the real-time and accurate grasp of the stress state, deformation trend, and potential safety hazards of the support system, and escorting the safety of slopes and road traffic.

[0027] 3: The overall structure of the integrated retaining and protecting temporary slope support system of the utility model is simple. All components are of assembled design, which is convenient for installation, disassembly, and maintenance, has strong practicability and applicability, and can also be recycled repeatedly, thereby reducing material consumption and costs.

Finally, pass the bolt 903 through the through screw hole 902 and the fixed screw hole 801 in sequence to fix the fixed block 9 at the end of the fixed cross beam 8 to prevent the fixed cross beam 8 from sliding out of the horizontal connection hole 103 and the through connection hole 201 (or directly connect the guard net column 2 with the vertical connection hole 102 through threads). By analogy, install multiple combinations of retaining columns 1 and guard net columns 2 at the bottom of the slope. Then, install the retaining board 3 between any two adjacent retaining columns 1 through the corresponding baffle installation grooves 104 in pairs, and install the protective net 4 between any two adjacent guard net columns 2 through the corresponding guard net buckles 202 in pairs (when there is a threaded column 203 on the guard net column 2, adjust the installation height of the threaded column 203 through the clamping member 205, then adjust the height of each guard net buckle 202 by rotating the threaded sleeve ring 204, and finally install the protective net 4). Next, fix one end of the steel cable 5 in the slope soil through an anchor rod (which can be a newly installed anchor rod or an existing anchor rod on the slope). Pass the other end of the steel cable 5 through the tops of all the guard net columns 2 in sequence (there is a through hole for the steel cable 5 to pass through at the top of the guard net column 2. In a further solution, a fixed pulley for the steel cable 5 to turn can be provided at the tops of the two outermost guard net columns 2), and then fix it in the slope soil on the other side through an anchor rod. Finally, set at least one tension sensor 6 on the steel cable 5.
