Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a diaphragm wall construction protection device. Background Technology

[0002] A diaphragm wall (or simply diaphragm wall) is a continuous reinforced concrete wall constructed underground as a water-cutting, seepage-proof, load-bearing, and water-retaining structure. Diaphragm walls are typically constructed on the ground using a trenching machine. Along the perimeter of the deep excavation project, a narrow, deep trench is excavated under slurry wall protection conditions. After cleaning the trench, a reinforcing cage is placed inside, and then underwater concrete is poured using the tremie method to form a unit trench segment.

[0003] Before constructing the trench for the diaphragm wall, a guide wall must be built. The guide wall is crucial to ensuring the accurate positioning of the diaphragm wall and the quality of the trench. During construction, the guide wall often bears static and dynamic loads from the reinforcing cage, the duct used for pouring concrete, the drilling rig, etc.

[0004] However, during the construction process, the grab bucket of the trenching machine will repeatedly collide with the guide wall. Due to the weight and high strength of the grab bucket, and the limitation of the operator's skill level, the repeated collision of the grab bucket with the guide wall can easily cause damage to the guide wall. In severe cases, it may even cause cracks in the guide wall, affecting the construction quality of the trenching of the ground wall and the construction quality of the diaphragm wall. Utility Model Content

[0005] The purpose of this invention is to provide a protective device for diaphragm wall construction, thereby improving the construction quality of diaphragm walls.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Construction protection device for diaphragm walls, which includes:

[0008] A support frame, comprising a base plate and an inclined plate, the inclined plate being connected to the base plate and forming an angle with the base plate, and an adjustment assembly connecting two support frames to allow the two inclined plates to face each other, the adjustment assembly being able to adjust the distance between the two support frames;

[0009] A limiting plate is disposed on the side of the base plate away from the inclined plate, and the limiting plate is perpendicular to the base plate.

[0010] In some embodiments, the support frame is further provided with a straight support plate, which is vertically mounted on the base plate. One end of the inclined plate is connected to the base plate, and the other end is connected to the straight support plate.

[0011] In some embodiments, the support frame is further provided with a diagonal brace, the diagonal brace being set at an angle to the straight support plate, and the diagonal brace connecting the straight support plate and the diagonal plate.

[0012] In some embodiments, the angle between the inclined plate and the base plate is α, where 50° ≤ α ≤ 70°.

[0013] In some embodiments, a support wheel is provided on the side of the straight support plate opposite to the inclined plate, and the height of the support wheel is adjustable.

[0014] In some embodiments, two support wheels are provided, a driving member is provided on the straight support plate, and a synchronous shaft is provided at the output end of the driving member. The synchronous shaft connects the two support wheels so as to drive the support wheels to rise and fall synchronously.

[0015] In some embodiments, the limiting plate includes a mounting plate and a top plate, the mounting plate being perpendicularly connected to the top plate, and the mounting plate being detachably connected to the base plate.

[0016] In some embodiments, the base plate is provided with a groove, and the mounting plate is embedded in the groove.

[0017] In some embodiments, the bottom wall of the groove is provided with a first mounting hole, the mounting plate is provided with a second mounting hole, and the mounting plate and the bottom plate are connected by a connector passing through the first mounting hole and the second mounting hole.

[0018] In some embodiments, the adjustment assembly includes a first tube, a second tube, and a locking member. The first tube and the second tube are provided with a plurality of perforations spaced apart along their length. The inner diameter of the first tube is larger than the outer diameter of the second tube. The first tube is connected to one of the base plates, and the second tube is connected to the other base plate. The first tube can be inserted into the second tube and locked by inserting the locking member into the perforations.

[0019] The beneficial effects of this utility model are:

[0020] By adjusting the distance between the two support frames using the adjusting component, the distance between the two limiting plates is made smaller than the distance between the two guide walls, so that the two limiting plates are positioned between the two guide walls and the base plate is placed on the guide walls. Then, the adjusting component is adjusted in the opposite direction so that the limiting plates abut against the side of the guide wall and are fixed in place. Subsequently, when trenching the diaphragm wall, the grab bucket of the trenching machine will be blocked by the inclined plate when it approaches the guide wall and guided by the inclined plate to be between the two support frames, thereby reducing the possibility of damage to the guide wall and improving the construction quality of the diaphragm wall.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] like Figures 1 to 3 As shown, this application provides a diaphragm wall construction protection device, which protects the guide wall during diaphragm wall construction. The diaphragm wall construction protection device includes a support frame 1 and a limiting plate 3. The support frame 1 includes a base plate 11 and an inclined plate 12. The inclined plate 12 is connected to the base plate 11 and is set at an angle to the base plate 11. An adjustment component 2 is connected between the two support frames 1 so that the two inclined plates 12 can face each other. The adjustment component 2 can adjust the distance between the two support frames 1. The limiting plate 3 is set on the side of the base plate 11 away from the inclined plate 12 and is set perpendicular to the base plate 11.

[0037] First, adjust the distance between the two support frames 1 by adjusting component 2 so that the distance between the two limiting plates 3 is less than the distance between the two guide walls, so that the two limiting plates 3 are located between the two guide walls and the bottom plate 11 is placed on the guide wall. Then, adjust the adjusting component 2 in the opposite direction so that the limiting plates 3 abut against the side of the guide wall and are fixed. Then, when the diaphragm wall is trenched, the grab bucket of the trenching machine will be blocked by the inclined plate 12 when it approaches the guide wall and guided by the inclined plate 12 to be between the two support frames 1, thereby reducing the possibility of damage to the guide wall and improving the construction quality of the diaphragm wall.

[0038] like Figure 3 As shown, in some embodiments, the included angle between the inclined plate 12 and the base plate 11 is α, 50°≤α≤70°. This angle allows the grab bucket to descend as quickly as possible after contacting the inclined plate 12, minimizing the force exerted on the inclined plate 12 and extending its service life. Furthermore, to further extend the service life of the inclined plate 12, such as... Figure 1 and Figure 3 As shown, the support frame 1 also includes a straight support plate 13, which is vertically disposed on the base plate 11. One end of the inclined plate 12 is connected to the base plate 11, and the other end is connected to the straight support plate 13, thereby forming a stable triangular structure with the base plate 11, the inclined plate 12, and the straight support plate 13, ensuring overall stability and improving service life. For example, the base plate 11, the inclined plate 12, and the straight support plate 13 can be integrally formed.

[0039] like Figure 1As shown, in some embodiments, the support frame 1 further includes a diagonal brace 14, which is connected between the straight support plate 13 and the inclined plate 12. The diagonal brace 14 is set at an angle to the straight support plate 13, thereby further supporting the inclined plate 12, further improving the stability of the inclined plate 12, and increasing its service life.

[0040] It should be noted that, due to the relatively long length of the guide wall, the base plate 11 and the inclined plate 12 are made of steel plates with a length of 2m-5m and a thickness of 10mm. Based on the aforementioned lengths of the base plate 11 and the inclined plate 12, multiple diagonal braces 14 are provided, and the multiple diagonal braces 14 are spaced apart along the length direction of the base plate 11.

[0041] like Figure 3 As shown, in some embodiments, the limiting plate 3 includes a mounting plate 31 and a top plate 32. The mounting plate 31 and the top plate 32 are vertically connected. The mounting plate 31 is detachably connected to the base plate 11, so that when not in use, the limiting plate 3 can be removed from the base plate 11 and the base plate 11 can be placed directly on the ground for easy placement. Since the mounting plate 31 is installed on the side of the base plate 11 away from the inclined plate 12, that is, on the lower end face of the base plate 11, and the lower end face of the base plate 11 is placed on the ground during use, in order to ensure the stability of the overall device, in some embodiments, the base plate 11 is provided with a groove 111, and the mounting plate 31 is embedded in the groove 111, so that the mounting plate 31 does not protrude from the groove 111, avoiding instability caused by protrusion.

[0042] Specifically, to fix the mounting plate 31, a first mounting hole is provided on the bottom wall of the recess 111, and a second mounting hole is provided on the mounting plate 31. The mounting plate 31 and the base plate 11 are connected by a connector 7 passing through the first and second mounting holes. Exemplarily, one of the first and second mounting holes is a through hole, and the other is a screw hole; the connector 7 is a bolt. In the current embodiment, for ease of installation, the first mounting hole is a screw hole, and the second mounting hole is a through hole.

[0043] Based on the length of the base plate 11, in some embodiments, multiple limiting plates 3 are provided, and the multiple limiting plates 3 are spaced apart along the length direction of the base plate 11. Similarly, multiple slots 111 are also provided on the base plate 11. Providing multiple limiting plates 3 facilitates installation and disassembly.

[0044] like Figure 1As shown, in some embodiments, a support wheel 4 is provided on the side of the straight support plate 13 away from the inclined plate 12. The height of the support wheel 4 is adjustable. When it is necessary to change the placement position or adjust the distance between the two support frames 1, the height of the support wheel 4 is lowered to support the base plate 11, so that the support wheel 4 supports the ground. The entire device can then be moved with the assistance of personnel or a crane for easy movement. In the current embodiment, two support wheels 4 form a group. The number of support wheels 4 can be set differently depending on the length of the base plate 11, and no specific limitation is made here. To improve automation, a drive component 5 is also provided on the straight support plate 13. The output end of the drive component 5 is provided with a synchronous shaft 6. The synchronous shaft 6 connects the two support wheels 4 in the same group, thereby driving the two support wheels 4 to rise and fall synchronously through the drive component 5. The synchronous shaft 6 is a commonly used component in the prior art, and its connection relationship is also a conventional technical means, such as a bevel gear connection. After moving into position, the support wheels 4 can be adjusted to rise, so that the base plate 11 contacts the ground.

[0045] It is understood that in some alternative embodiments, the height of the support wheel 4 can also be adjusted manually. For example, a threaded sleeve is provided on the straight support plate 13, and a screw is provided on the support wheel 4. The screw is screwed onto the threaded sleeve, and the height of the support wheel 4 is adjusted by rotating the screw. Both of the above adjustment methods can provide space for the adjustment of the support wheel 4 by adding shims under the base plate 11 using a crane or by the operator.

[0046] like Figure 1 and Figure 2 As shown, in some embodiments, the adjusting assembly 2 includes a first tube 21, a second tube 22, and a locking member 24. The first tube 21 is connected to one of the base plates 11, and the second tube 22 is connected to the other base plate 11. The first tube 21 and the second tube 22 extend away from the inclined plate 12. The inner diameter of the first tube 21 is larger than the outer diameter of the second tube 22, allowing the second tube 22 to be inserted into the first tube 21. Both the first tube 21 and the second tube 22 have a plurality of through holes 23 along their length. When the second tube 22 is inserted into the first tube 21, the first tube 21... The perforation 23 on the first tube 21 can be aligned with the perforation 23 on the second tube 22. At this time, the locking member 24 can be inserted into the perforation 23 to lock the first tube 21 and the second tube 22. That is to say, by adjusting the length of the mutual insertion of the first tube 21 and the second tube 22, the distance between the two inclined plates 12 can be adjusted. On the one hand, it is suitable for guide walls of different distances. On the other hand, when the fixed ground connection wall construction protection device is used, the distance between the two inclined plates 12 can be reduced first, so that the two abutting plates 32 are first located between the two guide walls. Then the distance between the two inclined plates 12 can be increased so that the abutting plates 32 abut against the guide wall.

[0047] For example, locking member 24 may be, but is not limited to, a pin or a combination of bolt and nut.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
