[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] like Figure 1-5As shown, a steel sheet pile support construction auxiliary guide frame includes a steel template 1 and connecting plugs 2 installed on both sides of the steel template 1. When in use, according to the width of the steel template 1 used, two adjacent connecting plugs 2 are inserted around the bottom of the deep foundation pit with the width of the steel template 1 as the spacing. The steel template 1 is lifted by a crane, and the steel template 1 is moved between the two connecting plugs 2 in a manner that fits the bottom of the deep foundation pit, that is, in a low-height lifting manner. Two receiving grooves 11 are provided on one side of the connecting plug 2, and the top and bottom edges of the connecting plug 2 are located An L-shaped guide groove 9 is provided at the position of the storage groove 11, and a baffle 6 for supporting the side of the steel template 1 is inserted in the storage groove 11. The top and bottom edges of the baffle 6 are fixedly connected with two connecting shafts 10 that are slidably connected to the guide groove 9. After the steel template 1 is lifted between the two connecting plugs 2 at a low height, the baffle 6 is pulled out of the storage groove 11 by slidingly connecting the connecting shaft 10 with the guide groove 9, and the angle of the baffle 6 is adjusted to fit the other side of the steel template 1, and one side of the connecting plug 2 extends outward, and A block 7 is plugged into the surface, and limiting plates 18 for resisting the baffle 6 are installed on both sides of the block 7, and a threaded tube 3 is embedded and rotatably connected to the side of the block 7 facing away from the connecting column 2, and a threaded rod 4 is threadedly connected to the threaded tube 3. One end of the threaded rod 4 is movably connected to a ground nail 5. The ground nail 5 is plugged in at a certain distance from the connecting column 2, and then the threaded rod 4 is rotated to realize the threaded rod 4 entering and exiting the threaded tube 3, so as to adjust the distance between the ground nail 5 and the block 7, and then the ground nail 5 and the threaded rod 4 are rotated to connect the block 7 and the connecting column 2. The rotation connection of the threaded tube 3 enables the block 7 to slide partially at the extension of the connecting column 2 to a specified height. After fixing the relative positions of the block 7 and the connecting column 2, the limit plate 18 is rotated. As shown in the figure, the limit plate 18 is L-shaped. Therefore, the two vertical outer walls of the limit plate 18 are respectively attached to the block 7 and the baffle 6. A supporting force can be applied to one side of the baffle 6 to prevent the pressure exerted by the deep foundation pit wall on the steel formwork 1 from being transmitted to the baffle 6, causing the baffle 6 to turn outward and loosen, causing the steel formwork 1 to move loose.

[0026] In order to preliminarily fix the steel template 1 and the connecting column 2: the surface of the baffle 6 is hollowed out, and the two sides of the surface of the steel template 1 and the hollowed-out parts of the connecting column 2 and the baffle 6 are connected by bolts, such as Figure 4 As shown, bolts are passed through the hollowing out of the baffle plate 6 surface and the steel template 1 and then threadedly connected with the connecting plug column 2. The steel template 1 can be installed between the two connecting plug columns 2 and after being fitted by the baffle plate 6, the relative positions of the baffle plate 6, the steel template 1 and the connecting plug column 2 are fixed. A turbine spring shaft 12 is rotatably connected to the block 7. Both ends of the turbine spring shaft 12 extend outwardly through the block 7, and two limit plates 18 are respectively fixed at both ends of the turbine spring shaft 12. The set turbine spring shaft 12 can force the limit plates 18 to rotate to the position shown in FIG. Figure 4 The state shown in the figure, therefore, before installing the clamping block 7, it is necessary to move the limiting plate 18 to a vertical state.

[0027] In order to further fix the position of the limit plate 18 and the limit shaft 8: the block 7 is located on one side of the limit plate 18 and is embedded with an insertion strip 16, and the insertion strip 16 is located on the side outside the block 7 and is fixedly connected with a latch 17 for penetrating the limit plate 18. The insertion strip 16 is used to ensure that the latch 17 can only slide in one direction, and the position of the limit plate 18 can be further fixed by passing the latch 17 through the limit plate 18 to prevent the limit plate 18 from rotating due to force. The limit shaft 8 is penetrated by the extension part of the block 7 and the connecting plug column 2. After the block 7 moves to the corresponding position on the connecting plug column 2, the block 7 can be fixed on the connecting plug column 2 by passing the limit shaft 8 through the block 7 and the connecting plug column 2:

[0028] In addition, a manual switch is provided between the limit shaft 8 and the insertion strip 16 and the block 7. The manual switch comprises a spring rod 14 fixed to the block 7 and a connecting plate 15 fixed to the telescopic end of the spring rod 14. The connecting plate 15 is used to realize the synchronous connection of the insertion strip 16 or the limit shaft 8 with the corresponding spring rod 14, that is, the relative position of the limit shaft 8 or the insertion strip 16 and the block 7 is fixed by the elastic extension of the spring rod 14. Figure 4 and Figure 5 As shown, at this time, the spring rod 14 is in a normal state, and by applying a pulling force to the connecting plate 15 to overcome the spring rod 14, the spring rod 14 and the connecting plate 15 are forced to move, thereby realizing that the limit shaft 8 is separated from the connecting column 2 or the latch 17 is separated from the limit plate 18, and the block 7 can slide on the connecting column 2 or the limit plate 18 can rotate:

[0029] In addition, the connecting plates 15 in the two manual switch parts are respectively fixed on the insertion strip 16 and the limit shaft 8, and the two spring rods 14 are respectively arranged parallel to the insertion strip 16 and the limit shaft 8. The manual switch part also includes a pull rope 13 with one end fixed on the connecting plate 15 and the other end moving along the length direction of the spring rod 14 and passing through the block 7. The pull rope 13 passing through the block 7 is also installed at a position near the turbine spring shaft 12 on the limit plate 18. Figure 4 and Figure 5 As shown, three pull ropes 13 are provided, and the three pull ropes 13 all pass through the block 7. The difference is that the pull rope 13 located at the limit shaft 8 and the limit plate 18 first moves a distance in the direction parallel to the spring rod 14 and then passes through the raised L-shaped part on the block 7. Therefore, by pulling one end of the pull rope 13, the connection plate 15 can be moved or the limit plate 18 can be rotated. In addition, before the block 7 is installed, one end of the pull rope 13 is tied to the end of the threaded barrel 3, that is, at this time the limit plate 18 is vertical, the limit shaft 8 is displaced, and the pin 17 is not in contact with the limit plate 18.

[0030] Working principle: according to the width of the steel formwork 1, several connecting posts 2 are respectively inserted around the bottom of the deep foundation pit, and the steel formwork 1 is hoisted between two connecting posts 2 by a crane at a low height. The baffle 6 is first pulled, and then the relative positions of the baffle 6, the steel formwork 1 and the connecting posts 2 are pre-fixed with bolts, and then the distance between the ground nail 5 and the block 7 is adjusted, and the ground nail 5 is inserted into the bottom of the deep foundation pit, and the block 7 is stuck in the extension part of the connecting post 2, and the connecting plate 15 connecting the limit shaft 8 is loosened. The pull rope 13 of the connecting plate 15 is released, and the spring rod 14 at the corresponding position elastically contracts, so that the limit shaft 8 passes through the block 7 and the connecting column 2. Then, the pull rope 13 of the connecting limit plate 18 is released, and the limit plate 18 is rotated to fit the baffle 6 and the block 7 under the elastic rotation and reset action of the turbine spring shaft 12. Finally, the pull rope 13 of the connecting plate 15 on the connecting strip 16 is released, and the spring rod 14 at the corresponding position elastically contracts and resets, so that the strip 16 drives the latch 17 to move through the limit plate 18.
