[0002] The seaside curtain structure is a commonly used engineering structure to prevent wind and seawater infiltration. However, the existing windproof structure safety curtain structure has average strength. It needs to withstand the pressure brought by the complex geological and hydrological environment of the sea. When affected by factors such as wave impact, tidal fluctuations and groundwater level changes, its structure is prone to deformation or even damage. This lack of strength will lead to the gradual loss of anti-seepage function, which will affect the safety and stability of the entire seaside project. In addition, the existing curtain structure does not have a stress support effect. In the seaside environment, the structure needs to withstand stress from all directions, including wind, horizontal The impact of waves in the straight direction and the soil pressure in the vertical direction, etc., due to the lack of an effective stress support structure, the curtain structure cannot effectively disperse and resist these stresses; at the same time, during construction, the steel cages of the existing seaside curtains cannot be well combined and connected, which is inconvenient during construction and requires workers to spend more time and energy to operate, which not only increases the construction cost, but also faces more risks from changes in the marine environment, such as damage to unfinished construction parts due to bad weather, etc., and the construction efficiency is also slow.

[0016] S3. Casting stage: by pouring concrete in the first curtain hole and the second curtain hole, the concrete and the steel wall are solidified into an integral concrete curtain wall, and the land is divided into a front soil foundation and a rear soil foundation. At the same time, a rectangular casting frame is laid on the top of the concrete curtain wall, and the concrete is poured in the rectangular casting frame and solidified together with the concrete curtain wall;

[0017] S4. Stress support stage: At this time, the front soil foundation is excavated downward to expose one side of the concrete curtain wall, and holes are drilled downward along the middle of the concrete curtain wall. When drilling holes, the internal steel cage is staggered, and the drilling edge extends into the rear soil foundation. Then, the supporting steel cylinder of the stress support rod group is inserted through the holes of the concrete curtain wall and inserted into the rear soil foundation, and one side of the supporting steel cylinder is fixed to the concrete curtain wall to form a whole;

[0018] S5. Pulling stage: Since plug-in steel rods are inserted in the supporting steel cylinder, the plug-in steel rods are pulled outwards by an anchor puller and fastened by anchors. During the process of pulling out the plug-in steel rods, each inner movable block slides outwards along the supporting steel cylinder, so that the conical head of the inner movable block gradually pushes each cone nail outwards from the side opening and is inserted laterally into the soil of the rear foundation.

[0019] Based on the above technical solution, the movable plug-in device includes a mobile body and a flap rotatably installed on the front side of the mobile body, flip motors for driving the flap rotation are installed on both sides of the mobile body, and a plurality of first telescopic rods are rotatably installed on the rear side of the flap, and are hinged to the rear side of the flap through the first telescopic rods, a clamping and conveying assembly for clamping and conveying the sliding connecting rod to insert into the sliding slot is installed in the middle of the front side of the flap, and a hammer pressing assembly for pressurizing and hammering the sliding connecting rod is provided on the top of the flap.

[0021] Based on the above technical solution, a plurality of second telescopic rods for pushing the two inner movable splints to relative displacement are installed on both sides of the outer frame plate. A plurality of movable guide rods penetrating the outer frame plate are fixed on the outer sides of the two inner movable splints, and a layer of anti-slip rubber pad is attached to the surface of the roller.

[0022] Based on the above technical solution, the hammer pressing assembly includes an extension plate fixed on the top of the flap, a jack is provided on the top of the extension plate, and the jack is provided directly above the clamping assembly. A winch is installed on one side of the extension plate, and the winch is connected to the jack through a wire rope.

[0023] By adopting the above technical solution, the present invention has the following advantages:

[0024] The present invention forms a reinforced wall by splicing a plurality of reinforced cages together, and vertical steel plates are arranged on both sides of the reinforced cages, and adjacent reinforced cages are clamped into a whole by using sliding slots and sliding connecting rods. This structural design makes the reinforced wall more integrated, and is more convenient in combined construction compared with the poor assembly of steel bars in the prior art, effectively improving the structural strength of the reinforced wall, and can better maintain the stability of the structure when subjected to various external forces in the coastal environment, providing more reliable internal support for the entire curtain structure;

[0025] In addition, a rectangular casting frame is arranged on the top of the concrete curtain wall, and the vertical steel bars on the upper side of the steel bar wall are arranged inside the rectangular casting frame. At the same time, the inner side of the steel bar wall is connected with the transverse steel bars and the annular steel bars and staggered and tied with the top vertical steel bars, so that the concrete and the steel bars can be better combined during the casting process, so that the rectangular concrete wall is pressed on the top of the concrete curtain wall as a whole, thereby enhancing the overall strength and stability of the top of the concrete curtain wall. This structure can better resist external pressure.

[0026] The setting of the stress support rod group provides effective stress support for the concrete curtain wall. The stress support rod group includes a support steel cylinder and a plug-in steel rod. The support steel cylinder first provides a lateral support for the concrete curtain wall. When the plug-in steel rod is pulled outward by the anchor puller, the conical head of the inner movable block can push the cone nail outward and insert it into the soil of the rear foundation, thereby improving the lateral contact point between the support steel cylinder and the soil and the anti-pulling effect. In addition, this stress support can effectively disperse the stress of the curtain structure to the surrounding soil, thereby solving the problem of the lack of stress support effect of the curtain structure in the prior art and improving the stability of the curtain structure in the complex stress environment near the sea.

[0027] The invention can greatly improve the assembly efficiency of the steel bar wall by using the movable plug-in device. The clamping and conveying components in the movable plug-in device can clamp and convey the sliding connecting rod to insert into the sliding slot, and the flap can be flipped horizontally and vertically. Horizontal placement can quickly load materials, and vertical flipping can adjust the angle of the sliding connecting rod clamped by the clamping and conveying components to better correspond to the sliding slot; and when the flap is placed horizontally, the second telescopic rods arranged on the left and right sides of the outer frame plate can push the inner movable clamping plate to relatively displace to adapt to sliding connecting rods of different sizes, and allow the inner movable clamping plate to effectively clamp the sliding connecting rod, and when the flap is placed vertically, the inner movable clamping plate is adapted to fit with the protrusions on both sides of the sliding connecting rod through the rollers, and the sliding connecting rod adapted to be clamped by the rollers is conveyed downward by providing power through the conveying motor, so that the sliding slots of the two steel cages can be quickly aligned for plugging. Compared with the inconvenient steel bar assembly in the prior art, the splicing of the steel cages can be completed more quickly and accurately, reducing the construction time and labor costs;

[0028] In addition, the hammer pressing assembly of the movable plug-in device can further provide convenience for the installation and use of the sliding connecting rod. The winch of the hammer pressing assembly controls the retraction and extension of the jack, and the jack can hammer the sliding connecting rod clamped by the clamping assembly when it is in a vertical state, thereby preventing the sliding connecting rod from being stuck when inserted into the sliding slot and being unable to go down. Compared with the inconvenience of construction and the need for a large amount of manpower in the prior art, it can improve the construction speed and reduce the difficulty of construction while ensuring the construction quality.

DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0046] like Figure 1-14As shown in the figure, the present invention provides a technical solution for a windproof structural safety building curtain facing the sea, which includes a concrete curtain wall 3 and a steel wall 5 condensed in the middle of the concrete curtain wall 3; the steel wall 5 is composed of a plurality of steel cages 51 spliced ​​together, and vertical steel plates 52 are respectively fixed on both sides of each steel cage 51, and sliding grooves 53 are vertically opened on the outer sides of the vertical steel plates 52, and the sliding grooves 53 on one side of each two adjacent steel cages 51 are arranged oppositely, and the relatively arranged sliding grooves 53 are inserted and slidably arranged from top to bottom, which are used to clamp the plurality of steel cages 51 to each other to form an integral steel wall 5, specifically, the sliding grooves 53 are arc-shaped grooves, and the protrusions on both sides of the sliding connecting rod 54 are adapted to slide and connect with the sliding grooves 53, and the outer sides of the sliding grooves 53 are set to be open The sliding slot 53 can surround not less than half of the area of ​​the side protrusion of the sliding connecting rod 54, thereby realizing sliding connection and splicing the two adjacent steel cages 51 together. When assembling, the sliding connecting rod 54 is adapted and slidably connected with the sliding slots 53 of the two opposite steel cages 51 through the protrusions on both sides thereof. Through this splicing method, the steel wall 5 forms an integral structure. Compared with the poor assembly of steel bars in the prior art, its integrity is greatly enhanced, and there is no need to hang the entire steel wall 5. The steel cages 51 can be assembled and spliced ​​one by one, which is simpler and more convenient to use. In addition, in a coastal environment, it can effectively resist various external forces, such as wave impact, pressure changes caused by tidal fluctuations, etc., and provide more reliable internal support for the entire concrete curtain wall 3.

[0047] Among them, a rectangular casting frame 6 is set on the top of the concrete curtain wall 3, and the vertical steel bars on the upper side of the steel wall 5 are located inside the rectangular casting frame 6. Moreover, a plurality of transverse steel bars 61 and annular steel bars 62 are connected to the inner side of the steel wall 5, and the transverse steel bars 61 and the annular steel bars 62 are staggered and tied with the vertical steel bars on the top of the steel wall 5, respectively. By pouring concrete into the rectangular casting frame 6, a rectangular concrete wall connected to the top of the concrete curtain wall 3 is formed, so that the rectangular concrete wall and the vertical steel bars on the upper side of the steel wall 5 can be better combined during the pouring process, thereby enhancing the overall strength and stability of the top of the concrete curtain wall 3 and better resisting external pressure.

[0048] In addition, two stress support rod groups 7 are downwardly penetrated on one side of the concrete curtain wall 3. The stress support rod group 7 includes a plurality of support steel cylinders 71. The support steel cylinder 71 itself provides a lateral support effect for the concrete curtain wall 3. A plurality of plug-in steel rods 72 are inserted into the inner side of the support steel cylinder 71, and a plurality of inner movable blocks 75 are fixed on the plug-in steel rods 72. The plug-in steel rods 72 and the inner movable blocks 75 can improve the supporting strength of the support steel cylinder 71. A plurality of side openings 73 are provided in an annular array on the surface of the support steel cylinder 71, and a cone nail 732 is movably inserted in each side opening 73, and a spring 731 is sleeved on the cone nail 732. The spring 731 is fixed to the inner wall of the support steel cylinder 71, and is elastically connected to the side opening 73 in the support steel cylinder 71 through the spring 731 on one side of the cone nail 732. A cone head 751 is integrally provided on one side of each inner movable block 75, and the opposite side of each cone nail 732 is in contact with the surface of the cone head 751. When the supporting steel cylinder 71 pulls the inner movable block 75 and the conical head 751 to move outward, the conical head 751 can push each conical nail 732 outward and insert it into the soil bottom. During the installation process, the plug-in steel rod 72 is pulled outward by the anchor rod puller, and the inner movable block 75 on the plug-in steel rod 72 slides outward, and the conical head 751 on one side of the inner movable block 75 will push outward the conical nail 732 that is in contact with the surface of the conical head 751. Under the elastic action of the spring 731, the conical nail 732 is laterally inserted into the soil of the rear soil foundation a2 from the side opening 73 on the surface of the supporting steel cylinder 71. The conical nail 732 is inserted into the soil, which increases the lateral contact points between the supporting steel cylinder 71 and the soil, and improves the anti-pullout effect. This stress support can effectively disperse the stress on the curtain structure to the surrounding soil, solves the problem of lack of stress support effect of the curtain structure in the prior art, and improves the stability of the curtain structure in the complex stress environment near the sea.

[0049] In the above technical solution, one side of the concrete curtain wall 3 and the supporting steel cylinder 71 is provided with an anchor 74 for fixing the plug-in steel rod 72, and the middle of the inner movable block 75 and the conical head 751 is provided with a grouting hole 752 connected to the inner side of the supporting steel cylinder 71. Therefore, after pulling out the plug-in steel rod 72, concrete can be poured into the supporting steel cylinder 71, and the concrete can flow down along the grouting hole 752 into the inner bottom of each supporting steel cylinder 71 in turn. In this way, after solidification in the later stage, not only the quality strength of the supporting steel cylinder 71 can be further strengthened, but also the internal plug-in steel rod can be 72 and the inner movable block 75 are bonded and fixed, so that even if the external anchor 74 of the plug-in steel rod 72 is damaged, it can still support the plug-in steel rod 72 and the inner movable block 75, ensuring that the cone nail 732 is not elastically retracted to the inner side of the supporting steel cylinder 71 by the spring 731, thereby improving the strength and increasing the stability of use. In addition, a connecting plate 701 is provided on one side of each anchor 74, and is locked to one side of the concrete curtain wall 3 through the connecting plate 701. The connecting plate 701 can fix the entire supporting steel cylinder 71 to the concrete curtain wall 3, thereby improving the connection effect between them.

[0050] Among them, after the rectangular concrete wall in the rectangular casting frame 6 is solidified and formed, the outer plate of the rectangular casting frame 6 is removed, and one of the stress support rod groups 7 is obliquely penetrated by the middle of the rectangular concrete wall, that is, the supporting steel cylinder 71 of the stress support rod group 7 is obliquely penetrated by the middle of the rectangular concrete wall, and is staggered between the transverse steel bars 61, so that the transverse steel bars 61 can provide the effect of upper and lower clamping, thereby improving the overall support strength.

[0051] In this embodiment, the movable plug-in device includes a mobile body 9 and a flap 91 rotatably mounted on the front side of the mobile body 9. Flip motors 911 for driving the flap 91 to rotate are mounted on both sides of the mobile body 9. Therefore, the flap 91 can be placed horizontally or vertically under the rotation of the flip motor 911, and two first telescopic rods 912 are rotatably mounted on the rear side of the flap 91, and are hinged to the rear side of the flap 91 through the first telescopic rods. In this way, the extension and retraction of the first telescopic rods 912 can also push and pull to control the angle of the flap 91, which can be used together with the flip motor 911 to ensure the stable flipping action of the flap 91.

[0052] The front middle part of the flap 91 is provided with a clamping and conveying assembly 92 for clamping and conveying the sliding connecting rod 54 to insert into the sliding slot 53. The clamping and conveying assembly 92 includes an outer frame plate 921 installed in the middle of the flap 91. Two inner movable clamping plates 923 are relatively movable on the inner side of the outer frame plate 921, and a connecting frame 922 is fixed on one side of the inner movable clamping plate 923. Three rollers 924 are rotatably installed on the opposite sides of the two inner movable clamping plates 923 through a rotating shaft, and a close-fitting groove 9241 is provided in the middle of the roller 924 to fit the raised portions on both sides of the sliding connecting rod 54. The close-fitting groove 9241 is arc-shaped, thereby increasing the force-bearing area of ​​the raised portion of the sliding connecting rod 54 and improving the friction force. A layer of anti-skid rubber pad is attached to the surface of the roller 924, which contacts the raised portion of the sliding connecting rod 54 through the anti-skid rubber pad to further improve the anti-skid effect and clamping effect. A conveying motor 925 is installed on one side, and the conveying motor 925 is respectively connected to the rotating shaft on one side of each roller 924 through a transmission chain. When the flap 91 is placed vertically, the conveying motor 925 on the connecting frame 922 drives the roller 924 to rotate through the transmission chain, and the inner movable splint 923 fits with the protrusions on both sides of the sliding connecting rod 54 through the roller 924. The conveying motor 925 provides power to allow the sliding connecting rod 54 that is adapted and clamped by the roller 924 to be transported downward. In addition, an upper cross plate 55 with a larger diameter can be fixed on the top of the sliding connecting rod 54. In this way, when the sliding connecting rod 54 is inserted downward into the sliding slot 53, the upper cross plate 55 can be clamped on the upper side of the upper cross plate 55 so as not to be completely immersed in the sliding slot 53. The increased area of ​​the upper cross plate 55 can also increase the contact surface with the jack sinker 932, allowing the jack sinker 932 to hammer more accurately onto the upper side of the upper cross plate 55.

[0053] In addition, a plurality of second telescopic rods 926 for pushing the two inner movable splints 923 for relative displacement are respectively installed on both sides of the outer frame plate 921. The first telescopic rod 912 and the second telescopic rod 926 can adopt the cylinder, hydraulic cylinder or electric telescopic rod in the prior art to realize the telescopic action. Therefore, the second telescopic rod 926 can push the two inner movable splints 923 for relative displacement to adapt to sliding connecting rods 54 of different sizes, and provide the inner movable splints 923 with a tightening force on the sliding connecting rod 54, so as to make the rolling conveying of the roller 924 more stable. Two movable guide rods 927 that penetrate the outer frame plate 921 are fixed on the outer sides of the two inner movable splints 923, which can provide effective guidance for the relative movement of the inner movable splints 923.

[0054] A hammer pressing assembly 93 for pressurizing and hammering the sliding connecting rod 54 is provided on the top of the flap 91. The hammer pressing assembly 93 includes an extension plate 931 fixed on the top of the flap 91. A jack head 932 is provided on the top of the extension plate 931. The jack head 932 is arranged just above the clamping assembly 92. A winch 933 is installed on one side of the extension plate 931. The winch 933 is connected to the jack head 932 through a wire rope. The winch 933 controls the retraction and extension of the jack head 932 through the wire rope. When the flap 91 is placed vertically and the clamping assembly 92 clamps the sliding connecting rod 54, the jack head 932 is located directly above the sliding connecting rod 54. The free fall of the jack sinker 932 can hammer the sliding connecting rod 54 to prevent the sliding connecting rod 54 from being stuck in the middle of the sliding slot 53 due to the influence of sand and gravel, so that the sliding connecting rod 54 can be inserted into the sliding slot 53 more quickly and accurately, thereby improving the splicing efficiency of the steel cage 51. In addition, the diameter of the jack sinker 932 is smaller than the distance between the rollers 924 on the two inner movable splints 923. In this way, when the rollers 924 of the two inner movable splints 923 are opened, the jack sinker 932 will not hit the rollers 924 when falling, thereby reducing the impact of its use.

[0055] A construction method for a windproof structure safety building curtain near the sea, comprising the following construction steps:

[0056] S1. Drilling stage: First, the axis and outline of the curtain are laid out on the ground to determine the position and range of the curtain. According to the position of the laid-out line, the trench of the curtain is excavated by a mixing drill to drill the first curtain hole b1 and the second curtain hole b2, and drainage is performed. Then, the steel cage 51 is placed in the first curtain hole b1 and the second curtain hole b2 respectively, so that the vertical steel plates 52 and the sliding slots 53 of the two steel cages 51 are arranged opposite to each other. This step lays the foundation for the subsequent assembly of the steel wall 5 and the pouring of the concrete curtain wall 3;

[0057] S2. Assembly stage: The sliding connecting rod 54 is placed on the movable plug-in device, and the clamping and conveying assembly 92 in the movable plug-in device will clamp the sliding connecting rod 54, wherein the inner movable clamping plate 923 on the inner side of the outer frame plate 921 can adjust the relative position through the second telescopic rod 926 to adapt to the sliding connecting rods 54 of different sizes, and the sliding connecting rod 54 is conveyed to a suitable position under the rotation of the roller 924 driven by the conveying motor 925, and the flap 91 can be adjusted by horizontal and vertical flipping of the flipping motor 911 and the first telescopic rod 912 to adjust the angle. After vertical flipping, it can better align with the sliding card slots 53 on the opposite side of the two steel cages 51, so that the anti-slip rubber pad of the sliding card slot 53 contacts and clamps the sliding connecting rod 54, and the conveying motor 925 provides power The roller 924 is adapted to the clamped sliding connecting rod 54 and transported downward, so that the adapted protrusions on both sides of the sliding connecting rod 54 are respectively slidably inserted into the sliding slots 53 of the two steel cages 51. After the transportation is completed, the rollers 924 of the two inner movable clamps 923 are opened, and the top of the sliding connecting rod 54 will be partially exposed above the sliding slot 53. If the sliding slot 53 slides smoothly, it can slide down freely under the action of its own weight. If there is sand and gravel inside the sliding slot 53 or it is not positioned and stuck, the winch 933 controls the jack head 932 to fall freely through the wire rope. The jack head 932 is lowered to hammer the stuck sliding connecting rod 54 downward, so that the two steel cages 51 can be connected and assembled to form an integral steel wall 5.

Casting stage: Concrete is cast into the first curtain hole b1 and the second curtain hole b2, so that the concrete and the steel wall 5 are solidified into an integral concrete curtain wall 3, thereby dividing the land into a front soil base a1 and a rear soil base a2. At the same time, a rectangular casting frame 6 is laid on the top of the concrete curtain wall 3, and concrete is cast into the rectangular casting frame 6 so that it is solidified together with the concrete curtain wall 3. In this process, the vertical steel bars on the upper side of the steel wall 5 are located inside the rectangular casting frame 6, and the transverse steel bars 61 and the annular steel bars 62 on the inside are staggered and tied with the top vertical steel bars. This layout allows the concrete and the steel bars to be better combined, thereby enhancing the strength of the concrete curtain wall 3;

[0059] S4. Stress support stage: At this time, the front soil foundation a1 is excavated downward to expose one side of the concrete curtain wall 3, and holes are drilled obliquely downward along the middle of the concrete curtain wall 3, and the holes are extended into the rear soil foundation a2. Then, the support steel cylinder 71 of the stress support rod group 7 is inserted through the holes of the concrete curtain wall 3 and inserted into the rear soil foundation a2, and then one side of the support steel cylinder 71 is fixed to the concrete curtain wall 3 to form a whole, and the support steel cylinder 71 provides lateral support for the concrete curtain wall 3;

[0060] S5. Pulling stage: Since the support steel cylinder 71 is interspersed with the plug-in steel rod 72, after the plug-in steel rod 72 is pulled outward by the anchor rod pulling instrument, concrete can be poured into the support steel cylinder 71, and the concrete can enter the inner bottom of each support steel cylinder 71 in sequence along the leakage hole 752. In this way, after solidification in the later stage, not only can the quality strength of the support steel cylinder 71 be further strengthened, but the internal plug-in steel rod 72 and the internal movable block 75 can also be bonded and fixed, and the plug-in steel rod 72 and the support steel cylinder 71 are fastened to one side of the concrete curtain wall 3 by the anchor 74. In the process of pulling out the above-mentioned plug-in steel rod 72, each internal movable block 75 slides outward along the support steel cylinder 71, and the conical head 751 on one side of the internal movable block 75 gradually pushes each cone nail 732 outward from the side opening 73, and inserts it laterally into the land of the rear soil foundation a2. This increases the lateral contact points between the supporting steel cylinder 71 and the ground and the anti-pulling effect, and effectively disperses the stress of the curtain structure into the surrounding soil.
