Description

Technical Field

[0001] This utility model belongs to the field of steel sheet pile support technology in building engineering, specifically a steel sheet pile support anti-displacement device for building engineering. Background Technology

[0002] A foundation pit is a deep pit dug by humans, typically used for building construction, underground engineering, or quarrying. Steel sheet pile support in building construction refers to the construction process of using steel sheet piles to achieve foundation pit support. The steel sheet piles and support sheets are directly erected on both sides of the foundation pit. During steel sheet pile support construction, preventing displacement is paramount for the safety of steel sheet pile foundation pit construction. With increasing emphasis on building safety, various types of steel sheet pile support and displacement prevention devices for building construction have emerged on the market.

[0003] However, the sheet pile support and anti-displacement devices currently available in the market have poor overall stability during the construction of sheet piles and support plates. During use, the sheet piles and support plates may shift or deviate from the foundation pit. The sheet piles and support plates are also susceptible to contact wear and bearing wear, which affects the service life of the sheet piles and support plates, impacts the construction safety of sheet pile support, and is detrimental to the use of sheet pile support and anti-displacement devices in construction projects. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a steel sheet pile support anti-displacement device for building engineering is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The steel sheet pile support anti-displacement device for building engineering of this utility model includes steel sheet piles installed on both sides of the foundation pit, and a first support plate and a second support plate correspondingly arranged on the inner side of the steel sheet piles. The steel sheet piles are fixed to the foundation of the foundation pit by reinforcing bars. The reinforcing bars are inclined downward through the steel sheet piles and extend into the foundation of the foundation pit, and the reinforcing bars are used to tightly connect the steel sheet piles with the side of the foundation pit. The bottom ends of the first support plate and the second support plate are vertically inserted into the foundation at the bottom of the foundation pit. A transverse brace is provided between the first support plate and the second support plate, and the top of the first support plate and the second support plate extending out of the foundation pit are laterally connected to the anchor rod. The left end of the anchor rod extends laterally out of the outer side of the support plate and is provided with an anchor pile. The anchor pile is inclinedly buried in the foundation on both sides of the top of the foundation pit, and the anchor pile and the anchor rod are used to press the support plate tightly against the inner side of the steel sheet pile at the corresponding position.

[0006] Furthermore, at least one set of buffer sections is arranged between the first support plate and the left sheet pile, and between the second support plate and the right sheet pile. Each set of buffer sections consists of a crossbeam and a wooden wedge placed on the crossbeam, and the crossbeam is arranged along the length of the foundation pit.

[0007] Furthermore, the vertical height of the first and second support plates exceeds the depth of the pit, and both the first and second support plates are made of steel plates.

[0008] Furthermore, the cross bracing is provided in at least one set, and each set of cross bracing is composed of steel beams, with the ends of the cross bracing fixed to the corresponding support plate surface by fasteners.

[0009] Furthermore, the reinforcing ribs are provided in at least two sets, each set of reinforcing ribs consisting of a tension post, an insertion cone installed at the bottom of the tension post, and a fixing block installed at the top of the tension post.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model utilizes the combination of reinforcing ribs, cross bracing, anchor rods, and anchor piles to horizontally and vertically limit the steel sheet piles and two sets of retaining plates. This ensures that the steel sheet piles and two sets of retaining plates remain stable during use, significantly improving the overall stability and preventing displacement. Furthermore, the buffer section provides toughness between the steel sheet piles and retaining plates, reducing contact and pressure wear during use and effectively lowering the probability of breakage. This provides effective protection for the steel sheet piles and retaining plates, extending their service life and facilitating the widespread use of this anti-displacement device for steel sheet pile support in construction projects.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] like Figure 1-4 As shown in the embodiment of this utility model, a steel sheet pile support anti-displacement device for building engineering includes steel sheet piles 2 installed on both sides of a foundation pit 1, and a first support plate 4 and a second support plate 9 correspondingly arranged inside the steel sheet piles 2. The steel sheet piles 2 are fixed to the foundation of the foundation pit 1 by reinforcing ribs 8. The reinforcing ribs 8 obliquely pass through the steel sheet piles 2 and extend into the foundation of the foundation pit 1, and the reinforcing ribs 8 are used to tightly connect the steel sheet piles 2 to the side of the foundation pit 1. Among them, the reinforcing ribs 8 are provided in at least two sets. Each set of reinforcing ribs 8 consists of a tension column 801, an insertion cone 803 installed at the bottom of the tension column 801, and a fixing block 802 installed at the top of the tension column 801. The tension column 801 and the insertion cone 803 can extend into the foundation of the side of the foundation pit 1. When the reinforcing ribs 8 are in use, the fixing block 802 is located on the inner side of the steel sheet pile 2. The fixing block 802, the tension column 801 and the insertion cone 803 are integrated connection structures. The lateral width of 2 exceeds the lateral diameter of the support column 801; the bottom ends of the first support plate 4 and the second support plate 9 are both vertically inserted into the foundation at the bottom of the pit 1. A horizontal brace 7 is provided between the first support plate 4 and the second support plate 9. There is at least one set of horizontal braces 7. Each set of horizontal braces 7 is composed of steel beams. The ends of the horizontal braces 7 are fixed to the corresponding support plate surface by fasteners, which are not limited to screws or bolts. The top of the first support plate 4 and the second support plate 9 are connected laterally to the portion extending out of the pit 1 by anchor rods 5. The left end of the anchor rod 5 extends laterally out of the outer side of the support plate and is provided with an anchor pile 6. The anchor pile 6 is obliquely buried in the foundation on both sides of the top of the pit 1. The anchor pile 6 and the anchor rod 5 are used to press the support plate against the inner side of the corresponding steel sheet pile 2. The steel sheet pile 2, the anchor pile 6 and the anchor rod 5 are existing technologies, and their structural principles are well-known technologies on the market, so they will not be described in detail here.

[0022] In this embodiment, at least one set of buffer sections 3 are arranged between the first support plate 4 and the left sheet pile 2, and between the second support plate 9 and the right sheet pile 2. Each set of buffer sections 3 consists of a horizontal beam 301 and a wooden wedge 302 placed on the horizontal beam 301, and the horizontal beam 301 is arranged along the length of the pit 1. The vertical height of the first support plate 4 and the second support plate 9 exceeds the depth of the pit 1. The first support plate 4 and the second support plate 9 are both made of steel plates. The wooden wedge 302 is placed on the horizontal beam 301. When the first support plate 4 is subjected to external force, it will move towards the steel plate. When the sheet pile 2 is displaced in the direction, the wooden wedge 302 will produce a certain degree of elastic deformation on the crossbeam 301, which can offset the external pressure between the first support plate 4 and the sheet pile 2, thereby reducing the contact wear between the first support plate 4 and the sheet pile 2. The second support plate 9 is also placed on the crossbeam 301 by the wooden wedge 302 to reduce the contact wear between the second support plate 9 and the sheet pile 2. The crossbeam 301 is a horizontally placed piece of wood with a rectangular cross-section. The rectangular wood pieces are arranged horizontally.

[0023] Working principle: This sheet pile support anti-displacement device for construction projects, before assembly, pre-installs the sheet piles 2 on the side of the foundation pit 1 with reinforcing ribs 8. A buffer section 3, consisting of horizontal timbers 301 and wooden wedges 302, is installed inside the sheet piles 2. Then, a first support plate 4 or a second support plate 9 is installed inside the buffer section 3. The bottom end of the first support plate 4 or the second support plate 9 is vertically inserted into the foundation at the bottom of the foundation pit 1. Anchor piles 6 and anchor rods 5 are used to hold the top surface of the first support plate 4 or the second support plate 9 on the top surface of the foundation pit 1. Finally, the horizontal bracing section 7 pushes the first support plate 4 and the second support plate 9 outwards, allowing the sheet piles 2, the first support plate 4, and the second support plate 9 to move together. Sheet 9 provides stable support to both sides of the foundation pit. The combination of anchor piles 6 and anchor rods 5, along with the horizontal bracing 7, enables horizontal positioning of sheet piles 2, the first support plate 4, and the second support plate 9. The reinforcing ribs 8 provide vertical positioning of sheet piles 2, the first support plate 4, and the second support plate 9. The buffer 3 provides toughness between sheet piles 2 and the support plate, reducing contact wear and bearing wear when sheet piles 2 and the support plate come into contact. This ensures that sheet piles 2, the first support plate 4, and the second support plate 9 remain stable during use, improving the overall stability and integrity of sheet pile support and effectively preventing displacement or deviation of sheet pile support.
