Description

Technical Field

[0001] The present application relates to the technical field of foundation pit support, and in particular to a three-axis mixing pile water-stop curtain structure. Background Art

[0002] The triaxial mixing pile water-stop curtain is a deep foundation reinforcement and water-stop technology, which is often used in underground projects such as subways, tunnels, and basements to provide groundwater isolation and increase the stability of foundation pit support. This technology is achieved by forming a continuous cement-soil wall underground, which can effectively prevent groundwater infiltration and soil sliding; as the depth increases, the pressure of the soil and the moisture in the soil on the cement-soil wall will continue to increase, causing the cement-soil wall to have the risk of rollover; it is necessary to add a reinforcement structure to the cement-soil wall to prevent the cement-soil wall from rolling over.

[0003] For example, a Chinese patent (CN221072701 U) discloses a foundation pit water-stop curtain structure, which includes continuous fixed piles arranged on the inner wall of the foundation pit, and is characterized in that the fixed piles are arranged vertically, and a gap is opened between two adjacent fixed piles, and embedded piles are arranged in the gap, and a cross beam is arranged on the inner wall of the fixed pile around the circumference of the foundation pit, and connecting nails are arranged on the cross beam, and the connecting nails extend into the fixed piles or are embedded in the piles for fixing, and the cross beam is obliquely connected to the ground with an oblique support rod.

[0004] In the above structure, the fixed piles are supported by beams and oblique support rods. The oblique support rods can contact the soil at the bottom of the foundation pit to provide lateral support force to the beams. However, since construction is required inside the foundation pit, the setting of the oblique support rods will hinder the construction.

[0005] In view of this, the purpose of the utility model is to provide a three-axis mixing pile water-stop curtain which has a stable structure and does not hinder the construction inside the foundation pit. Utility Model Content

[0006] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0007] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a three-axis mixing pile water-stop curtain structure, including: a plurality of mutually interlocking water-stop piles arranged on the inner wall of the foundation pit, angle plates are arranged at the inner corners of the water-stop piles, the angle plates are fixed on the water-stop piles by continuous nails, two adjacent angle plates are connected by a reinforcing plate group fixed on the water-stop piles, and the reinforcing plate groups on both sides of the angle plates are fixedly connected by main cross braces, so that the main cross braces can provide lateral support force to the reinforcing plate group.

[0008] During the working process, the setting of the angle plates and the reinforcement plate groups can connect the water stop piles to each other to prevent the water piles from tipping over. Due to the setting of the main cross brace plate, the main cross brace plate and the two adjacent reinforcement plate groups form a stable triangular structure. When the reinforcement plate group is subjected to the lateral pressure of the water stop piles, the main cross brace plate can give the reinforcement plate group a lateral thrust to further prevent the water piles from tipping over. The main cross brace plate is set at the corner, which occupies less space inside the foundation pit and will not hinder the construction inside the foundation pit.

[0009] Furthermore, the main transverse bracing plate and the reinforcement plate group are fixedly connected via the auxiliary transverse bracing plate, and a stable triangular structure is formed between the auxiliary transverse bracing plate, the reinforcement plate group and the main transverse bracing plate.

[0010] Furthermore, the reinforcing plate group is composed of a side plate and a middle plate connected to each other, one end of the side plate is inserted into the angle plate, and the other end of the side plate is fixedly connected to the middle plate through a connecting piece.

[0011] Furthermore, the connecting member is a plug plate with a U-shaped cross-section, two connecting screws are fixed in the plug plate, a connecting hole is set at one end of the side plate away from the angle plate, and connecting holes are set at both ends of the middle plate. The side plate and the middle plate are inserted in the plug plate, and the two connecting screws on the plug plate are respectively inserted in the connecting holes of the side plate and the middle plate, and fixed by nuts.

[0012] Furthermore, a pulling piece is inserted into the reinforcing plate group, and one end of the pulling piece away from the reinforcing plate group is inserted through the water stop pile and inserted into the soil.

[0013] Furthermore, the surface portion of the reinforcing plate group is concave and penetrates into the soil to form a pulling hole, a plurality of reinforcing ribs are inserted into the pulling hole, and the reinforcing ribs form a bent portion near one end of the reinforcing plate group, and concrete is poured in the pulling hole.

[0014] Furthermore, an anti-slip cylinder is fixedly arranged on the reinforcing plate group, the bending portion is arranged in the anti-slip cylinder, and concrete is poured in the anti-slip cylinder.

[0015] Furthermore, an anti-falling plate is fixedly arranged on the top of the angle plate, and the anti-falling plate is fixedly arranged on the top of the water-stop pile by continuous nails.

[0016] The beneficial effects of this application are:

[0017] 1. The setting of the main cross brace and the auxiliary cross brace can provide lateral support for the reinforcement plate group to prevent the water pile from tipping over. The main cross brace and the auxiliary cross brace are both set at the corners of the foundation pit, occupying less space inside the foundation pit and will not hinder the construction inside the foundation pit.

[0018] Second, the setting of the plug plate and the connecting screw rod can connect the side plate and the middle plate longitudinally, so as to avoid the influence of the firmness of the connection between the side plate and the middle plate on the squeezing of the water stop pile.

[0019] 3. The pulling piece can fix the reinforcing plate group on the water stop pile and give the water stop pile a lateral pulling force to resist the squeezing of the water stop pile by the soil and groundwater. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] A three-axis mixing pile water-stop curtain structure, comprising a plurality of mutually interlocking water-stop piles 1 arranged on the inner wall of a foundation pit, an angle plate 2 is arranged at the inner corner of the water-stop pile 1, the top of the angle plate 2 is integrally formed with the angle plate 2 to form an anti-drop plate 3, the angle plate 2 is fixedly arranged on the water-stop pile 1 by a plurality of continuous nails 4, the anti-drop plate 3 on the top of the angle plate 2 is fixedly arranged on the top surface of the water-stop pile 1 by the continuous nails 4, and the setting of the anti-drop plate 3 can prevent the angle plate 2 from sinking downward under the action of gravity;

[0037] Two adjacent angle plates 2 are fixedly connected by a reinforcing plate group 5 fixedly arranged on the water stop pile 1. The reinforcing plate group 5 is composed of a side plate 6 and a middle plate 7 connected to each other. The side plate 6 and the middle plate 7 are fixedly connected by a connecting piece 8. Specifically, one end of the side plate 6 is inserted on the angle plate 2, and a connecting hole 9 is arranged at the end of the side plate 6 away from the angle plate 2. Both ends of the middle plate 7 are provided with connecting holes 9. The connecting piece 8 is a plug plate 10 with a U-shaped cross section. The side plate 6 and the middle plate 7 are both inserted in the plug plate 10. Two connecting screws 11 are fixedly arranged on the plug plate 10. The two connecting screws 11 are respectively inserted in the connecting holes 9 of the side plate 6 and the middle plate 7, and are fixed by nuts 20. The setting of the plug plate 10 and the connecting screw 11 can prevent the connection between the side plate 6 and the middle plate 7 from being affected by the lateral pressure of the water stop pile 1.

[0038] Pulling pieces 12 are inserted into the side plates 6 and the middle plates 7, and the pulling pieces 12 can tightly fix the reinforcing plate group 5 on the water stop pile 1.
