Technical Field

[0001] This utility model belongs to the field of civil engineering technology, specifically, it relates to a composite inclined steel sheet pile support component for soft soil areas. Background Technology

[0002] In the field of building construction, steel sheet pile cofferdams are used for construction in soft soil areas. Soft soil areas usually have low bearing capacity, high compressibility and low shear strength. Therefore, special technology is needed to deal with soil deformation and stability issues when supporting such areas. Thus, steel sheet piles need to be freely combined to form a continuous and compact steel structure for retaining soil or water.

[0003] Existing traditional sheet piles are usually straight and are directly inserted into the soil. Because the contact area between the sheet pile and the soil is small, it is impossible to form a multi-point anchoring structure. Under severe weather conditions such as typhoons, the support components are prone to lateral displacement, which further reduces the stability of the support components. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a composite inclined steel sheet pile support component for soft soil areas that can overcome or at least partially solve the above problems.

The composite inclined pile is installed on a plug-in pile at the end of the installation rod. The inside of the plug-in pile is rotatably connected to a rotating rod through a bearing. Several rotating disks are fixedly connected to the surface of the rotating rod. An extension rod is slidably connected inside the rotating disk. Several through holes are equally spaced on the side wall of the plug-in pile, and the extension rod slides inside the through holes.

[0006] Preferably, the end of the plug is provided with a connector, wherein the connector includes a connecting block that can be detachably installed at the end of the plug, and a tapered head is fixedly connected to the end of the plug.

[0007] Preferably, the surface of the conical head is covered with a protective sleeve, and the surface of the protective sleeve is provided with friction grooves.

[0008] Preferably, the rotating disk has an arc-shaped groove inside, and the end of the extension rod slides inside the arc-shaped groove.

[0009] Preferably, the insert pile has several reinforcing plates fixedly connected inside, the rotating rod passes through to the center of the reinforcing plate, the surface of the reinforcing plate is provided with a guide groove, and the end of the extension rod slides inside the guide groove.

[0010] Preferably, a flange one is fixedly connected to the top of the plug-in pile, and a flange two is fixedly connected to the bottom of the mounting rod, with flange one and flange two being fixedly connected by bolts.

[0011] Preferably, an installation plate is fixedly connected to the top of the installation rod, and an anchor bar is fixedly connected to the top of the installation plate. Both the installation plate and the anchor bar are fixedly connected to the side wall of the cap beam.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Example 1

[0024] Reference Figures 1-5 A composite inclined steel sheet pile support component for soft soil areas includes a steel sheet pile body 1 and a capping beam 2 installed above the steel sheet pile body 1. An installation rod 3 is fixedly connected to the side wall of the capping beam 2, and a composite inclined pile 4 is detachably installed at the end of the installation rod 3. The composite inclined pile 4 is installed on a splice 41 at the end of the installation rod 3. A rotating rod 42 is rotatably connected to the inside of the splice 41 via a bearing. Several rotating disks 43 are fixedly connected to the surface of the rotating rod 42. An extension rod 44 is slidably connected inside the rotating disks 43. Several through holes 45 are equidistantly opened on the side wall of the splice 41, and the extension rod 44 slides inside the through holes 45. An arc-shaped groove 431 is opened inside the rotating disks 43, and the end of the extension rod 44 slides in the arc-shaped groove 431. Inside the groove 431, several reinforcing plates 46 are fixedly connected to the inside of the plug-in pile 41. The rotating rod 42 passes through to the center of the reinforcing plate 46. The surface of the reinforcing plate 46 is provided with a guide groove 461. The end of the extension rod 44 slides inside the guide groove 461. The top of the plug-in pile 41 is fixedly connected to a flange 6. The bottom of the mounting rod 3 is fixedly connected to a flange 7. The flange 6 and the flange 7 are fixedly connected by bolts. The top of the mounting rod 3 is fixedly connected to a mounting plate 31. The top of the mounting plate 31 is fixedly connected to an anchor bar 32. The mounting plate 31 and the anchor bar 32 are both fixedly connected to the side wall of the crown beam 2. The top of the rotating rod 42 is fixedly connected to a rhomboid column 421, which is located in the cavity of the flange 6.

[0025] In this utility model, during use, the sheet pile body 1 is first driven into the soil of the soft soil area by a pile driver. Then, several sheet pile bodies 1 are spliced ​​together to form a barrier to shield the soft soil area. At the same time, the capping beam 2 is connected to the top of the sheet pile body 1. Then, the installation rod 3 supports the other side of the capping beam 2. The composite inclined pile 4 is connected to the end of the installation rod 3, and the end of the composite inclined pile 4 is driven into the soil of the soft soil area. The support strength of the capping beam 2 is ensured by the double support of the sheet pile body 1, the installation rod 3, and the composite inclined pile 4.

[0026] The end of the insert pile 41 is inserted into the soil by a pile driver. Then, by rotating the rotating rod 42 inside the insert pile 41, several rotating disks 43 are rotated. The rotation of the rotating disks 43 can drive the arc-shaped groove 431 to change its angle, thereby moving the extension rod 44 inside the arc-shaped groove 431 outward along the through hole 45. This increases the contact area with the soil, thereby further improving the support performance of the composite inclined pile 4. At the same time, with the reinforcement plate 46 installed, the insert pile 4 can be further strengthened. The strength of the internal cavity is improved, and the displacement guiding performance of the through hole 45 can be further improved by opening the guide groove 461. With the setting of the rhomboid column 421, it is convenient for workers to use tools to rotate the rhomboid column 421, thereby driving the rotating rod 42 to rotate synchronously. After the steel sheet pile body 1, the installation rod 3 and the composite inclined pile 4 are installed, concrete grout is poured in the soft soil area. After the concrete grout solidifies, it can further ensure the firmness between the steel sheet pile body 1, the installation rod 3 and the composite inclined pile 4.

[0027] With the top flange 6 of the plug-in pile 41, it can be stacked with the end flange 7 of the mounting rod 3 and then connected by threaded bolts. The mounting rod 3 and the composite inclined pile 4 are two detachable installations, which can reduce the difficulty of transportation. With the top anchor bar 32 of the mounting plate 31, when the mounting plate 31, the anchor bar 32 and the cap beam 2 are connected, the stress can be distributed, thereby improving the strength between the steel sheet pile body 1 and the mounting rod 3.

The connector 51 is threaded to the end of the plug 41. Then, the conical head 52 is positioned at the end of the plug 41. With the conical head 52, the end of the plug 41 can be better inserted into the soft soil. With the protective sleeve 53 and friction groove 54 on the surface of the conical head 52, when concrete slurry is injected into the soft soil area, the contact area and friction with the solidified slurry can be increased.
