Description

Technical Field

[0001] This invention relates to the field of well construction and production technology, specifically to a rooting wall support. Background Technology

[0002] As is generally known, the wall support is part of the shaft structure, an underground structure built along the shaft wall. Its function is to control formation pressure, maintain the stability of the surrounding rock of the shaft, and prevent the shaft from cracking and leaking water.

[0003] During the construction of the wellbore wall, due to the poor cementation properties of the rock strata (for example, in the applicant's actual construction conditions, the rock strata in the Mengxi area have poor cementation properties), wall protection construction must be carried out before using reverse drilling. The construction process is to construct the wellbore using the forward drilling method, and to support the wellbore wall while excavating downwards. The wellbore wall is supported by steel bars both vertically and circumferentially. The vertical steel bars are connected by straight threaded sleeves, and the steel bars are placed in the middle of the poured wellbore wall. After the support construction of the topsoil section and the weathered bedrock section is completed, plain concrete is used to backfill the wellbore, and then the reverse drilling process is used to construct the wellbore to prevent the wellbore wall from falling off and sliding down.

[0004] For example, patent application CN104533425A, published on April 22, 2015, entitled "A Construction Method for an Integral Cast-in-Place Section Wall Support for a Vertical Shaft," provides an integral cast-in-place section wall support for a vertical shaft and a construction method thereof. This invention relates to an integral cast-in-place section wall support. Specifically, it relates to an integral cast-in-place section wall support for a vertical shaft. This invention aims to solve the problem that existing water exploration drilling rigs can only operate on the inner side of the shaft wall, and under a certain drilling angle, the final hole position is difficult to exceed the rough diameter range, resulting in a small curtain radius and poor grouting effect. The integral cast-in-place section wall base of the vertical shaft of the present invention includes an outer wall, an inner wall, a wall base, two water exploration port pipes and a grout stop pad. The two water exploration port pipes are respectively embedded in the grout stop pad, and the wall base is connected to the outer wall. The bottom end face of the wall base is flush with the bottom end face of the inner wall. The inner wall is connected to the outer wall, and the upper end face of the inner wall is flush with the upper end face of the outer wall.

[0005] In the existing technology, the vertical reinforcement connection method of well wall supports mostly adopts straight thread sleeve connection. Construction personnel need to use tools to screw the straight thread sleeve into the previous vertical reinforcement that has been poured, and then screw the next vertical reinforcement to be constructed into the straight thread sleeve to achieve the connection of the two vertical reinforcements. During the construction of the wall support, due to the possibility of being suspended and the narrow space, the construction is inconvenient and requires a long construction time. Summary of the Invention

[0006] The purpose of this invention is to provide a rooting wall support to solve the above-mentioned problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An anchoring wall base includes multiple first vertical reinforcing bars and second vertical reinforcing bars that need to be connected. The first vertical reinforcing bars have been cast in concrete and their bottom ends are exposed. The second vertical reinforcing bars have not yet been cast. The base also includes a connecting unit, which includes an upper plug and a lower plug. The upper plug is fixedly installed at the bottom end of the first vertical reinforcing bar and has a hollow groove. The lower plug is fixedly installed at the top end of the second vertical reinforcing bar and has a movably arranged abutment rod. The two abutment rods are inserted into the hollow groove and their stroke drives the connection between the first and second vertical reinforcing bars.

[0009] The aforementioned upper and lower plug-in are sleeve-shaped cylindrical structures that can be plugged into each other.

[0010] As mentioned above, the hollow groove is T-shaped, meaning that the width of the top of the hollow groove is greater than the width of its bottom, so that it can abut against the rod and cooperate with it.

[0011] As described above, two abutment rods are mounted on the lower plug in a rotatable engagement manner via a positioning shaft, and the two abutment rods initially form an X-shaped cross assembly. Limiting chains are provided on the two abutment rods, and the limiting chains are used to position the abutment rods on the side wall of the lower plug.

[0012] As described above, under the limiting action of the limiting chain, the four ends of the two abutting rods are all located inside the lower plug, which facilitates the smooth insertion of the lower plug into the hollow groove.

[0013] As described above, a slot is provided in the middle of the inner wall of the top of the hollow groove, and a positioning rod is installed in the slot in a sliding fit manner. The top of the positioning rod and the inner wall of the slot are connected by a second elastic member.

[0014] As described above, four insertion holes are symmetrically opened at the top and bottom of both sides of the positioning rod. Two unlocking slots are symmetrically opened on the inner wall of the top of the hollow groove about the slot. The unlocking rod and the active rod are installed in the unlocking slot in a sliding fit. The active rod and the unlocking rod are connected to form an L-shaped rod. The active rod and the inner wall of the unlocking slot are connected by a third elastic member so that the active rod can be inserted into the insertion hole to perform positioning operation on the positioning rod.

[0015] As described above, the active rod has a concave surface on the side wall near the positioning rod, and the concave surface abuts against the abutting rod.

[0016] As described above, a docking mechanism is provided on the side wall of each of the two abutting rods that are close to each other, which is used to dock and lock the two abutting rods when they are parallel to each other.

[0017] As described above, two flat grooves are symmetrically opened on one side wall of the bottom of the hollow groove, and flat rods are installed in the two flat grooves in a sliding fit manner. The flat rods and the inner walls of the flat grooves are connected by a fifth elastic element.

[0018] The beneficial effects of the present invention are as follows: when it is necessary to connect the first vertical steel bar and the second vertical steel bar, the lower plug is inserted into the hollow groove of the upper plug, so that the end of the abutting member is pressed against the side wall of the hollow groove, and the second vertical steel bar is pulled down to realize the connection between the first vertical steel bar and the second vertical steel bar, making the connection between the first vertical steel bar and the second vertical steel bar more convenient and reducing the construction time of the construction personnel.

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 11 As shown, an embodiment of the present invention provides a rooting wall support, including a plurality of first vertical reinforcing bars 1 and second vertical reinforcing bars 2 that need to be connected. The first vertical reinforcing bars 1 have been cast in concrete and one end of their bottom is exposed, while the second vertical reinforcing bars 2 have not yet been cast. The support also includes:

[0035] The connecting unit 3 includes an upper plug 31 and a lower plug 32. The upper plug 31 is fixedly installed at the bottom end of the first vertical reinforcing bar 1. Both the upper plug 31 and the lower plug 32 can be cylindrical structures similar to sleeves in the prior art. The upper plug 31 is provided with a hollow groove 33. The lower plug 32 is fixedly installed at the top end of the second vertical reinforcing bar 2. The lower plug 32 is rotatably provided with abutting rods 34, and the two abutting rods 34 are inserted into the hollow grooves 33 to drive the fixed connection of the first vertical reinforcing bar 1 and the second vertical reinforcing bar 2.

[0036] Specifically, when the upper layer of concrete is poured for the well casing, vertical reinforcing bars are pre-installed at the bottom of the casing. After the vertical reinforcing bars are connected, the circumferential reinforcing bars are connected to form the well casing, and then concrete is poured to support the well wall. The 0-36m section of the well casing consists of topsoil and weathered bedrock, mainly backfill soil, gravelly fine-grained sandstone, fine-grained sandstone, and gravelly coarse-grained sandstone. The cementation properties of this rock strata are poor. During support, after the upper layer of the well casing is poured, the vertical reinforcing bars at its bottom are pre-installed outside the concrete. That is, the first vertical reinforcing bar 1 is pre-embedded after the upper layer is poured. Within the cast concrete, the bottom end of the first vertical reinforcing bar 1 is exposed at the bottom of the concrete. The second vertical reinforcing bar 2 is placed in the middle of the casting well wall. The first vertical reinforcing bar 1 has been cast into the concrete and its bottom end is exposed, allowing the second vertical reinforcing bar 2 to be connected to the first vertical reinforcing bar 1. In the prior art, the connection of the first vertical reinforcing bar 1 and the second vertical reinforcing bar 2 is mostly achieved by welding or using a straight threaded sleeve. However, when using welding, the welding equipment needs to be hoisted into the well, and the welding operation of the first vertical reinforcing bar 1 and the second vertical reinforcing bar 2 inside the well is relatively... To address the inconvenience and the lengthy time required for sequential welding of the first vertical reinforcing bar 1 and the second vertical reinforcing bar 2, using a threaded sleeve to connect them requires first screwing the sleeve into the first vertical reinforcing bar 1, and then screwing the second vertical reinforcing bar 2 into the sleeve. This method is cumbersome and inconvenient due to limited underground space, increasing the labor intensity for construction workers. Furthermore, the inconsistent lengths to which the first and second vertical reinforcing bars 1 and 2 are screwed into the threaded sleeve result in uneven welding of the first vertical reinforcing bar 1... The connection between the first vertical steel bar 1 and the second vertical steel bar 2 is unstable. However, in this embodiment, the construction worker only needs to insert the lower plug 32 on the second vertical steel bar 2 into the hollow groove 33 of the upper plug 31 of the first vertical steel bar 1, so that the end of the abutting rod 34 is pressed against the side wall of the hollow groove 33, causing the abutting rod 34 to rotate. Then, the second vertical steel bar 2 is pulled down so that the abutting rod 34 is pressed against the inner wall of the bottom of the hollow groove 33, thereby realizing the connection between the first vertical steel bar 1 and the second vertical steel bar 2. This makes the connection between the first vertical steel bar 1 and the second vertical steel bar 2 more convenient and reduces the construction time and labor intensity of the construction workers.

[0037] Furthermore, the upper plug-in 31 and the lower plug-in 32 are sleeve-shaped cylindrical structures that can be plugged into each other. Specifically, through the plugging and matching of the upper plug-in 31 and the lower plug-in 32, the first vertical steel bar 1 and the second vertical steel bar 2 can be connected relatively quickly, thereby improving the connection efficiency of the first vertical steel bar 1 and the second vertical steel bar 2.

[0038] Furthermore, the hollow groove 33 is T-shaped, meaning the width at the top of the hollow groove 33 is greater than its width at the bottom, so that the abutment member 34 can cooperate with it. Specifically, during the process of the construction personnel inserting the lower insert 32 on the second vertical steel bar 2 and the upper insert 31 of the first vertical steel bar 1 into the hollow groove 33, the abutment member 34 first enters vertically from the narrower bottom part of the hollow groove 33 to the wider top part, so that the end of the abutment member 34 is pressed tightly against the hollow groove 33. The abutment member 34 is forced to rotate on the inner wall of the top of the hollow groove 33, and then the second vertical steel bar 2 is pulled down. This causes the two ends of the abutment member 34 to slide from the wider part of the top of the hollow groove 33 to the bottom. Since the abutment member 34 is horizontal, it cannot slide out from the narrower part of the bottom of the hollow groove 33. As a result, the abutment member 34 remains inside the hollow groove 33 and abuts against the inner wall of the bottom of the hollow groove 33, so as to realize the connection between the first vertical steel bar 1 and the second vertical steel bar 2.

[0039] Furthermore, two abutment rods 34 are mounted on the lower plug 32 via a positioning shaft 35 in a rotatable engagement manner. The two abutment rods 34 initially form an X-shaped intersecting assembly. Limiting chains 4 are provided on the two abutment rods 34 to position them against the sidewalls of the lower plug 32. Each limiting chain 4 includes a limiting member 41 and a first elastic member 42. An arcuate groove 36 is provided on each of the two sidewalls of the lower plug 32. The sidewalls where the abutment rods 34 abut against the lower plug 32... The upper part is provided with a insertion groove 43, and a limiting member 41 is provided in the insertion groove 43 in a sliding fit manner. The limiting member 41 and the arc-shaped groove 36 are mutually abutting and fit together. The limiting member 41 and the inner wall of the insertion groove 43 are connected by a first elastic member 42. Specifically, before the lower insert 32 enters the hollow groove 33 of the upper insert 31, the arc-shaped end of the limiting member 41 on the abutting rod 34 is located in the arc-shaped groove 36. Under the pressing action of the first elastic member 42 (the first elastic member 42 is a component that can extend and retract and reset, preferably a spring), the limiting member 41 is abutted and fits together. 1. The abutment is pressed against the curved groove 36, so that the limiting member 41 positions the abutment member 34 on the lower plug 32, preventing the abutment member 34 from rotating without force. This ensures that the abutment member 34 is located inside the lower plug 32 (that is, both the top and bottom ends of the abutment member 34 are inside the lower plug 32, and the distance between the two top and bottom ends of the two abutment members 34 is less than the width of the lower plug 32 and also less than the width of the bottom of the hollow groove 33). This facilitates a more stable insertion of the lower plug 32 into the hollow groove 33. When the abutting rod 34 is pressed against the inner wall of the top of the hollow groove 33, under the squeezing force of the inner wall of the hollow groove 33, the abutting rod 34 is forced to rotate around the positioning shaft 35, so that the two top ends of the abutting rod 34 slide to both sides on the inner wall of the top of the hollow groove 33 until the two abutting rods 34 rotate to a position parallel to each other. When the abutting rod 34 rotates around the positioning shaft 35, the abutting rod 34 drives the limiting member 41 to slide out of the arc groove 36, so that the limiting member 41 no longer performs positioning operation on the abutting rod 34.

[0040] Furthermore, under the limiting action of the limiting branch chain 4, the four ends of the two abutting rods 34 are all located inside the lower plug 32, facilitating the smooth insertion of the lower plug 32 into the hollow groove 33. Specifically, under the pressing action of the first elastic member 42, the limiting member 41 on the abutting rod 34 is located in the arc groove 36, so that the limiting member 41 positions the abutting rod 34 on the lower plug 32, and the four ends of the abutting rod 34 are all located inside the lower plug 32 (that is, the width of the rectangle formed by the four ends of the two abutting rods 34 is less than that of the lower plug). The width of component 32 and the width of hollow groove 33 are designed to facilitate the smooth insertion of the lower plug-in 32 into the hollow groove 33. However, if all four ends of the two abutting rods 34 are located outside the lower plug-in 32, when inserting the lower plug-in 32 into the hollow groove 33, the abutting rods 34 on the lower plug-in 32 will prevent the lower plug-in 32 from entering the hollow groove 33 because the length of the abutting rods 34 is greater than the width of the bottom part of the hollow groove 33. The abutting rods 34 on the lower plug-in 32 will then prevent the lower plug-in 32 from entering the hollow groove 33. The construction personnel need to rotate the abutting rods 34 to insert the abutting rods 34 and the lower plug-in 32 into the hollow groove 33, which increases the work process of the construction personnel.

[0041] Furthermore, a slot 37 is provided in the middle of the inner wall of the top of the hollow groove 33. A positioning rod 38 is installed in the slot 37 in a sliding fit. The top of the positioning rod 38 and the inner wall of the slot 37 are connected by a second elastic member 39. Four insertion holes 310 are symmetrically opened on the top and bottom of the two side walls of the positioning rod 38 (that is, two insertion holes 310 are symmetrically opened on the top of the positioning rod 38, and two insertion holes 310 are symmetrically opened on the bottom of the positioning rod 38). Two unlocking slots 311 are symmetrically opened on the inner wall of the top of the hollow groove 33 about the slot 37. An unlocking rod 312 and an active rod 313 are installed in the unlocking slot 311 in a sliding fit. The active rod 313 and the unlocking rod 312 are connected to form a... The L-shaped rod, the active rod 313, and the inner wall of the unlocking groove 311 are connected by a third elastic element 314, so that the active rod 313 is inserted into the insertion hole 310 to position the positioning rod 38. Specifically, initially (that is, when the lower plug-in 32 is not inserted into the upper plug-in 31), the second elastic element 39 (the second elastic element 39 is a retractable and resetting element, preferably a spring) is in a compressed state. Since the unlocking rod 312 is inserted into the insertion hole 310 at the top of the positioning rod 38, the unlocking rod 312 positions the positioning rod 38, and the second elastic element 39 cannot rebound, so that the positioning rod 38 and the second elastic element 39 are both located in the slot 37. When the construction worker inserts the lower plug-in 32 into the slot 311, the second elastic element 39 cannot rebound, so that the positioning rod 38 and the second elastic element 39 are both located in the slot 37. When the lower insert 32 is inside the hollow groove 33, the abutment rod 34 is pressed against the inner wall of the top of the hollow groove 33. The abutment rod 34 rotates around the positioning shaft 35, causing the two top ends of the abutment rod 34 to slide to both sides on the inner wall of the top of the hollow groove 33. During the sliding of the abutment rod 34 to both sides on the inner wall of the top of the hollow groove 33, the abutment rod 34 pushes the active rod 313 and the unlocking rod 312 to slide away from the positioning rod 38 in the unlocking groove 311. This causes the unlocking rod 312 to slide out of the insertion hole 310 at the top of the positioning rod 38, releasing the positioning operation of the positioning rod 38. At the same time, the active rod 313 engages with the third elastic element 314 (the third elastic element 314 is a component capable of telescopic reset, preferably a spring). The spring compresses the third elastic element 314, putting it in a compressed state. Under the rebound of the second elastic element 39, the second elastic element 39 drives the positioning rod 38 to slide towards the outside of the slot 37 (that is, the second elastic element 39 drives the positioning rod 38 to slide towards the bottom of the hollow groove 33). This causes the positioning rod 38 to push the two abutting rods 34 towards the bottom of the hollow groove 33. The two abutting rods 34 slide until they are pressed against the inner wall of the bottom of the hollow groove 33 and then stop sliding. At this point, the two abutting rods 34 are parallel to each other. Through the rebound of the second elastic element 39, the abutting rods 34 quickly slide from the top to the bottom of the hollow groove 33, and the elastic force of the second elastic element 39 presses the abutting rods 34 firmly against the inner wall of the bottom of the hollow groove 33.After the abutting rods 34 cease sliding and the two abutting rods 34 disengage from the driving rod 313, under the rebound action of the third elastic element 314, the driving rod 313 and the unlocking rod 312 slide towards the end closer to the positioning rod 38. This causes the unlocking rod 312 to press against the positioning rod 38 and gradually slide into the insertion hole 310 at its top. The unlocking rod 312 then inserts into the insertion hole 310 at its top to position the positioning rod 38, preventing it from sliding further and thus stopping the abutting rods 34 from rotating.

[0042] Furthermore, the active rod 313 has a concave surface on the side wall near the positioning rod 38, and the concave surface abuts against the abutting rod 34. Specifically, when the active rod 313 and the abutting rod 34 abut against each other, the abutting rod 34 presses against the concave surface on the active rod 313, so that the abutting rod 34 can provide sliding power to the active rod 313 more stably, so that the active rod 313 can stably drive the unlocking rod 312 to slide in the unlocking groove 311, so that the unlocking rod 312 slides out of the insertion hole 310 at the top of the positioning rod 38 to release the positioning operation of the positioning rod 38.

[0043] Furthermore, a docking mechanism 5 is provided on the sidewall of each of the two abutting rods 34 on their adjacent sides. This mechanism is used to lock the two abutting rods 34 together when they are parallel. The docking mechanism 5 includes an auxiliary member 51 and a fourth elastic member 52. One end of each abutting rod 34 has a first groove 53, and the other end has a second groove 54. The auxiliary member 51 is slidably installed in the first groove 53. The auxiliary member 51 and the second groove 54 abut and lock together. The auxiliary member 51 and the inner wall of the first groove 53 are connected by the fourth elastic member 52. The other abutting rod 34 is positioned opposite to the first groove 53 and the second groove 54 on the locking rod (i.e., the two abutting rods 34...). The first groove 53 on the hollow groove 33 is provided at its top or bottom, and the second groove 54 on the two abutting rods 34 is provided at its bottom or top. Specifically, when the positioning rod 38 pushes the two abutting rods 34 to slide towards the bottom end of the hollow groove 33, when the two abutting rods 34 rotate to a position parallel to each other, the auxiliary part 51 on one abutting rod 34 slides into the second groove 54 on the other abutting rod 34, so that the auxiliary parts 51 on both abutting rods 34 slide into the second groove 54. Under the rebound and pressing action of the fourth elastic member 52, the auxiliary part 51 positions the two abutting rods 34, so that the two abutting rods 34 are more stably pressed against the inner wall of the bottom side of the hollow groove 33, preventing the abutting rods 34 from rotating.

[0044] Furthermore, two flat grooves 21 are symmetrically formed on one side wall of the bottom of the hollow groove 33. Flat rods 22 are installed in the two flat grooves 21 in a sliding fit. The flat rods 22 and the inner walls of the flat grooves 21 are connected by a fifth elastic member 23. Specifically, when the abutting rods 34 are parallel to each other and slide to abut against the side wall at one end of the bottom of the hollow groove 33, the second elastic member 39 and the positioning rod 38 abut against the abutting rods 34, causing the abutting rods 34 to compress the flat rods 22 and the fifth elastic member 23. This causes the fifth elastic member 23 and the flat rod 22 to provide a rebound force for the abutting rods 34, increasing the abutting force between the abutting rods 34 and the positioning rod 38. In addition, the fifth elastic member 23 and the flat rod 22 can provide a certain buffering effect on the compressive force applied by the second elastic member 39 and the positioning rod 38 to the abutting rods 34, preventing the abutting rods 34 from being damaged by excessive force.

[0045] In another embodiment of the present invention, the bottom end of the positioning rod 38 is provided with an inclined sleeve 26. An inclined through hole 27 is provided on each of the inner walls of the upper insert 31 near the two ends of the inclined sleeve 26, and the inclined through hole 27 communicates with the hollow groove 33. The inclined through hole 27 and the inclined sleeve 26 have the same inclination angle. Specifically, the inclination angle between the inclined sleeve 26 and the inclined through hole 27 (that is, the angle between the inclined sleeve 26 and the lower insert 32) is preferably 10-20 degrees, with the optimal inclination angle being 15 degrees. When the positioning rod 38 pushes the two abutting rods 34 to slide towards the bottom end of the hollow groove 33, the inclined... The inclined sleeve 26 abuts against the middle of the two abutting rods 34, causing the inclined sleeve 26 to push the two abutting rods 34 to the bottom inner wall of the hollow groove 33. At this time, the inclined sleeve 26 and the two inclined holes 27 are connected to each other. The construction personnel insert the anchor rod 25 into the inclined holes 27 and the inclined sleeve 26, so that the anchor rod 25 positions the inclined sleeve 26 and the positioning rod 38, so that the positioning rod 38 will not move, improving the stability of the connection between the first vertical steel bar 1 and the second vertical steel bar 2. At this time, the anchor rod 25 and the first vertical steel bar 1 and the second vertical steel bar 2 are mutually limited, greatly improving the stability.

[0046] In the prior art, the anchor bolt 25 and the inclined sleeve 26 are installed by drilling holes again after the well shaft construction is completed. In this embodiment, they are pre-cast, and the inclined sleeve 26 of the anchor bolt 25 is used as part of the whole mechanism. In this embodiment, the upper plug and the lower plug are prefabricated in the factory, and they can be directly connected to the first vertical steel bar 1 and the second vertical steel bar 2 by means of existing connection methods such as sleeve, welding, binding, screwing, etc.

[0047] The rooting wall bases provided in the various embodiments of the present invention not only greatly reduce the difficulty of binding work before construction, but also can be adapted and adjusted to a certain extent for situations that may be encountered on the construction site that are inconsistent with the actual detection situation or the actual operation situation is inconsistent with the design situation. More importantly, the strength of the connection is improved under such circumstances.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

The lower plug is equipped with two abutting rods in a rotatable engagement via a positioning shaft, and the two abutting rods are initially combined to form an X-shaped cross assembly. Limiting branches are provided on the two abutting rods, and the limiting branches are used to position the abutting rods on the side wall of the lower plug. Under the limiting action of the limiting chain, the four ends of the two abutting rods are all located inside the lower plug, which facilitates the smooth insertion of the lower plug into the hollow groove. A slot is provided in the middle of the inner wall of the top of the hollow groove. A positioning rod is installed in the slot in a sliding fit manner. The top of the positioning rod and the inner wall of the slot are connected by a second elastic member. The positioning rod has four symmetrical insertion holes on the top and bottom of both side walls. The hollow groove has two unlocking slots on the inner wall of the top, symmetrical about the slot. The unlocking slots are fitted with an unlocking rod and an active rod in a sliding fit. The active rod and the unlocking rod are connected to form an L-shaped rod. The active rod and the inner wall of the unlocking slot are connected by a third elastic element so that the active rod can be inserted into the insertion hole to position the positioning rod. The active rod has a concave surface on the side wall near the positioning rod, and the concave surface abuts against the abutting rod.

2. The rooting wall support according to claim 1, characterized in that, Each of the two abutting rods has a docking mechanism on its sidewall that is close to each other, which is used to lock the two abutting rods together when they are parallel to each other.

3. The rooting wall support according to claim 1, characterized in that, Two flat grooves are symmetrically formed on one side wall of the bottom of the hollow groove. Flat rods are installed in the two flat grooves in a sliding fit manner. The flat rods and the inner walls of the flat grooves are connected by a fifth elastic element.
