[0002] With the rapid development of China's economy and urban infrastructure construction, underground structures have become an important direction for current urban development and construction. As a common retaining structure, diaphragm walls are widely used in urban construction. The guide wall is one of the important structures of the diaphragm wall. Usually, during the excavation process, it will affect the inner soil of the guide wall, causing some soil to collapse. In response to this situation, the common treatment method is to directly backfill these parts with concrete during the pouring of the guide wall; if the collapsed part is large, double-sided formwork is used to complete the pouring of the guide wall, and then the collapsed part is backfilled and the slab section on the guide wall is constructed. The first treatment method will consume a large amount of concrete, resulting in a large waste; the second treatment method will have a great impact on the construction period and seriously hinder the subsequent construction.

[0027] The present application will now be described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0028] like Figures 1-5 As shown, an inner soil protection device suitable for guide wall construction includes a wire mesh 5 and a side formwork 3; the wire mesh 5 is arranged between the collapse area 1 and the guide wall casting area, and the side formwork 3 is arranged on the side of the guide wall casting area facing away from the wire mesh 5; a limit frame 4 is slidably provided between the collapse area 1 and the wire mesh 5.

[0029] The collapse zone 1 is usually located on the inner side of the guide wall 2, that is, on the inner side of the guide wall 2 before it is formed (cast).

[0030] The guide wall casting area is subsequently the area for pouring concrete. In this embodiment, a wire mesh 5 is arranged between the guide wall casting area and the collapse area 1. The wire mesh 5 can block the flow of concrete to the collapse area 1 to a certain extent. At the same time, the wire mesh 5 can also be "integrated" with the solidified concrete to play the role of a skeleton to ensure the firmness and stability of the guide wall 2.

[0031] The side formwork 3 is used to enclose together with the wire mesh 5 to form a guide wall casting area; in some other embodiments, the guide walls 2 often appear in parallel and at intervals, such as the forming of a certain ditch side wall. For such cases, abutment rods are often provided between the side formworks 3 corresponding to the two guide walls 2 to abut the two formworks.

[0032] The wire mesh 5 can be a mesh structure in which a number of steel wires are densely arranged and interlaced; and the smaller the distance between the steel wires in the wire mesh 5 is, the lower the probability of concrete passing through the wire mesh 5 is, that is, the waste caused by concrete flowing to the collapse area 1 can be avoided.

[0033] In order to ensure the support strength of the wire mesh 5 during the concrete pouring process, a limit frame 4 is specially provided. Specifically, the limit frame 4 is located between the collapse area 1 and the wire mesh 5, and plays a certain role in supporting and fixing the wire mesh 5.

[0034] The function of the limit frame 4 is to fix the wire mesh 5. In the actual process, after the guide wall 2 is poured and formed, the limit frame 4 can be withdrawn by sliding, that is, the limit frame 4 is pulled out, so as to be reused and reduce certain costs.

[0035] Under the action of the limit frame 4 and the wire mesh 5, a certain protection can be well formed for the guide wall pouring area, so as to avoid a large amount of concrete flowing into the collapse area 1 during the pouring process, further avoiding waste. At the same time, the wire mesh 5 can finally be directly embedded in the solidified guide wall 2, thereby increasing the strength of the guide wall 2.

[0036] In some further embodiments, the limit frame 4 includes a cross bar 41 and a plurality of vertical bars 40. The plurality of vertical bars 40 are arranged at intervals along the length direction of the cross bar 41, and a lifting handle is provided on the cross bar 41.

[0037] Specifically, the limit frame 4 includes a cross bar 41 and vertical bars 40. The number of vertical bars 40 is provided with a plurality to form sufficient support for the wire mesh 5.

[0038] A lifting handle is provided on the cross bar 41 for lifting the limit frame 4 upward after the guide pouring is completed or solidified.

[0039] Such as Figures 6-7 As shown, in some further embodiments, a fixing plate 30 is provided on the side of the side formwork 3 facing away from the guide wall pouring area.

[0040] In addition to being able to connect and fix the component units of the plurality of side formworks 3 together, the fixing plate 30 can also play the role of a reinforcing rib, that is, increasing the strength of the entire side formwork 3.

[0041] In some further embodiments, a clamping groove 31 is provided on the fixing plate 30 to facilitate the clamping of the abutting rod.

[0042] The clamping groove 31 can be specifically provided on the upper edge of the fixing plate 30, that is, the clamping groove 31 opens on the upper side wall of the fixing plate 30 and the side away from the guide wall 2 to facilitate the clamping or lapping of the abutting rod.

[0043] In some further embodiments, along the axial direction of the vertical bar 40 and away from the cross bar 41, the diameter of the vertical bar 40 gradually becomes smaller.

[0044] The diameter of the vertical bar 40 gradually decreases, which is beneficial to the subsequent lifting of the entire limit frame 4.

[0045] As shown Figures 8-10 In some further embodiments, the vertical rod 40 is hollow, and a relief notch 400 is provided at one end of the vertical rod 40 away from the cross bar 41. The relief notch 400 is formed on the peripheral wall of the cross bar 41. A rotating shaft 7 is provided inside the cross bar 41, and a rotating lever is rotatably provided on the rotating shaft 7. The rotating lever includes a supporting section 80 and a connecting section 81. One end of the supporting section 80 away from the rotating shaft 7 is hinged with a control rod 401, and one end of the control rod 401 away from the supporting section 80 penetrates the cross bar 41 along the axial direction of the vertical rod 40.

[0046] Specifically, the inside of the vertical rod 40 can also be hollow and can be a component such as a hollow tube.

[0047] The structure of the rotating lever is similar to that of a traditional lever. Among them, the connecting section 81 is the power arm, and the supporting section 80 is the resistance arm. When the control rod 401 is pressed down, under the action of the similar fulcrum of the rotating shaft 7, the supporting section 80 moves towards the inside of the vertical rod 40 and abuts against the inner wall of the vertical rod 40. When the control rod 401 is pulled up, the supporting section 80 will move towards the relief notch 400 and rotate out of the outside of the vertical rod 40. The purpose of this design is to increase the stability of the limiting frame 4 by adjusting the position of the supporting section 80, thereby increasing its supporting effect on the wire mesh 5 and concrete to a certain extent.

[0048] In some further embodiments, a plug hole 82 is provided on the connecting section 81, and a torsion spring is sleeved on the rotating shaft 7. One end of the torsion spring is inserted into the plug hole 82, and the other end of the torsion spring abuts against the inner wall of the vertical rod 40, so as to make the supporting section 80 tend to rotate out of the inside of the vertical rod 40 towards the relief notch 400.

[0049] In order to make the connecting section 81 always "actively" have the tendency to support the limiting frame 4, a torsion spring is sleeved on the rotating shaft 7. Under the action of the torsion spring, the rotating rod has a certain "self-driving force", so that the supporting section 80 is always located outside the vertical rod 40, that is, it supports the limiting frame 4 at a certain angle with the vertical rod 40. When the control rod 401 is pressed down, the elastic potential energy of the torsion spring is not enough to block the rotation of the rotating rod, so that the supporting section 80 rotates back into the inside of the vertical rod 40 to facilitate the extraction of the entire limiting frame 4.

[0050] In some further embodiments, a slot 410 corresponding to the vertical rod 40 is provided on the cross bar 41, and the control rod 401 passes through the cross bar 41 through the slot 410.

[0051] The position of the end of the connecting section 81 hinged with the control rod 401 will change with the up and down movement of the control rod 401. Therefore, by providing a slot 410 with the thickness direction length of the guide wall 2 on the cross bar 41, the interference between the cross bar 41 and the control rod 401 can be avoided.

[0052] In some further embodiments, a pressing rod 6 is further included, and one ends of a plurality of control rods 401 away from the connecting section 81 are connected to the pressing rod 6.

[0053] In order to uniformly control the movement of the rotating rods in a plurality of vertical rods 40, one ends of the control rods 401 passing through the cross bar 41 are uniformly connected to the same pressing rod 6 for easy operation.

[0054] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
