[0002] In the field of construction engineering, especially in foundation pit excavation projects, when the soil conditions are poor, pile support is a commonly used support method, and its main purpose is to prevent earthwork collapse and ensure the safety and stability of foundation pit construction. In this type of foundation pit excavation operation, steel support structures are usually used in conjunction, that is, steel beams on both sides and support columns in the middle are used to support and reinforce the piles on both sides to enhance the bearing capacity and stability of the entire support system.

[0003] In the support link of steel beams, it is often necessary to install a tripod for placing the supporting beams. For concrete piles, due to their large thickness, it is relatively convenient to install the tripod, and they can be fixed by drilling holes. However, when steel piles are used as supporting piles, they face many challenges. Steel piles are hard and difficult to perform complex fixing operations such as drilling holes like concrete piles. In addition, considering that steel piles have high requirements for installation convenience during construction, special installation components are generally not pre-set on steel piles. Most of them are installed by welding and other methods, which is relatively cumbersome. For this reason, we propose a composite pile for construction engineering. Utility Model Content

[0022] like Figure 1-Figure 4 As shown, a composite pile for construction engineering includes a Larsen steel sheet pile group, an I-beam 3 and a triangular support frame 6. The Larsen steel sheet pile group is a publicly available technology and will not be described in detail here. The Larsen steel sheet pile group is arranged in two rows, and the area between the two rows of Larsen steel sheet pile groups is the foundation pit location.

[0023] In this embodiment, by inserting two rows of Larsen steel sheet pile groups into the ground and then excavating the area between the two rows of Larsen steel sheet pile groups, the Larsen steel sheet pile groups can effectively support both sides of the foundation pit to prevent soil collapse and the like.

[0024] Furthermore, the Larsen steel sheet pile group includes a connecting pile plate 1 and a fixed pile plate 2. Both ends of the connecting pile plate 1 and the fixed pile plate 2 are provided with U-shaped grooves that can be snapped into each other. The snap-connection method of the connecting pile plate 1 and the fixed pile plate 2 is a public technology and will not be repeated here.

[0025] Furthermore, the I-beam 3 is arranged at a corresponding position on one side of two rows of fixed pile plates 2 away from each other, and baffles 4 are fixedly installed at both ends of the two corresponding rows of fixed pile plates 2 away from each other. The spacing between the baffle 4 and the inner end of the concave surface of the fixed pile plate 2 is adapted to the thickness of one end of the I-beam 3, and the I-beam 3 is snap-connected with the fixed pile plate 2 through the baffle 4.

[0026] In this embodiment, the plug-in buckle between the I-beam 3 and the fixed pile plate 2 can effectively enhance the overall stability of the combined pile. At the same time, the I-beam 3 can effectively share the vertical load of the Larsen steel sheet pile group.

[0027] Furthermore, the triangular support frame 6 is arranged at a corresponding position on one side where two rows of fixed pile plates 2 are close to each other, and a plug-in component is arranged on the fixed pile plate 2 at a position corresponding to the triangular support frame 6 .

[0028] In this embodiment, the triangular support frame 6 can be quickly installed through the plug-in assembly, and the plug-in assembly can further improve the overall connection correlation between the Larsen steel sheet pile group, the I-beam 3 and the triangular support frame 6, thereby further improving the overall stability of the combined pile.

[0029] Furthermore, the plug-in assembly includes a sliding card plate 5, a connecting card column 7 and a sliding card block 8. The sliding card plate 5 is arranged on the side wall of the fixed pile plate 2. The sliding card plate 5 is a hollow U-shaped plate. The sliding card plate 5 is arranged on the outer side wall of the fixed pile plate 2. The side walls of the triangular support frame 6 are both obliquely fixedly installed on the connecting card column 7. The connecting card column 7 and the outer side wall of the fixed pile plate 2 fit each other. The connecting card column 7 is fixedly installed on the sliding card block 8 at one end away from the triangular support frame 6. The position of the sliding card block 8 corresponds to the bottom position of the sliding card plate 5, and the sliding card block 8 is buckled at the inner bottom of the sliding card plate 5.

[0030] In this embodiment, by connecting the card column 7 and the sliding card block 8 connected to the triangular support frame 6, the triangular support frame 6 can be snapped into the corresponding position on the sliding card plate 5 along the corresponding position wall surface of the fixed pile plate 2 during installation, thereby completing the quick installation of the triangular support frame 6.

[0031] Furthermore, the plug-in assembly also includes a socket 9 and a column 10. The socket 9 is obliquely opened on the top wall of the sliding block 8, and the socket 9 is obliquely penetrated through the corresponding wall surfaces of the sliding card plate 5 and the I-beam 3 in turn, and there are two groups of sockets 9 on the I-beam 3, and the two groups of sockets 9 are vertically arranged. The column 10 is obliquely slidably plugged into the socket 9, and the bottom of the column 10 extends to the inside of the socket 9 on the I-beam 3.

[0032] In this embodiment, by obliquely inserting the plug column 10, the triangular support frame 6 can be limited by connecting the clamping column 7 and the sliding block 8, and the stability between the fixed pile plate 2 and the I-beam 3 can be further improved by the pressure of the soil.

[0033] Furthermore, the length of the sliding card plate 5 set on the left side of the fixed pile plate 2 is smaller than the length of the sliding card plate 5 set on the right side, and the connecting posts 7 on both sides of the triangular support frame 6 are installed on the side walls of the triangular support frame 6 in a displaced manner corresponding to the position of the sliding card plate 5 .

[0034] Furthermore, the height difference between the two groups of insertion holes 9 on the I-beam 3 is the same as the height difference between the sliding clamping plates 5 on the left and right sides of the fixed pile plate 2 .

[0035] In this embodiment, the two groups of columns 10 are staggered so that they are in a cross shape after installation. At the same time, each group of columns 10 and the fixed pile plates 2 and I-beams 3 at the corresponding positions form a triangle, thereby increasing the support points and stability points, further improving the stability and support effects.

[0036] The working principle and use process of this utility model:

[0037] When in use, two rows of Larsen steel sheet pile groups are inserted into the designated position by a pile driver, and then the I-beam 3 is inserted into the corresponding baffle 4 position on the fixed pile plate 2 by the pile driver until the top of the I-beam 3 and the top of the fixed pile plate 2 are in the same plane. Then, the area between the two rows of Larsen steel sheet pile groups is excavated by excavating equipment such as an excavator until the pre-excavation depth is reached. At this time, the triangular support frame 6 is slidably buckled in the sliding card plate 5 on the fixed pile plate 2 through the connecting card column 7 and the sliding card block 8. After the steel support beam is installed on the triangular support frame 6 by bolts or other connecting methods, the beams on both sides are supported by the support beams. After the support is stable, the foundation pit is excavated for the second time.
