Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
A novel deep foundation pit side slope supporting structure is shown in figures 1-4, a plurality of anchor rod holes are formed in a side slope 100, an I-shaped steel 102 is inserted into one side, far away from a deep foundation pit, of the side slope 100, and a plurality of rectangular holes 109 are formed in the I-shaped steel 102. Each i-section steel 102 corresponds to a row of anchor openings, and each rectangular opening 109 in i-section steel 102 corresponds to an anchor opening. Preferably, the distance between adjacent I-shaped steel 102 is 1.2 m or 2.4 m, and the distance between corresponding anchor rod holes of each row is also 1.2 m or 2.4 m; the distance between the adjacent rectangular holes 109 on each I-shaped steel 102 is 1-1.2 m, and the distance between the corresponding upper and lower adjacent anchor rod holes is also 1-1.2 m.
The anchor rod 101 is obliquely inserted into the anchor rod hole, and the anchor rod hole into which the anchor rod 101 is inserted is filled with expansion mortar. Slope 100 is stretched out to stock 101 one end, the other end of stock 101 is provided with V type trip 103, V type trip 103 is used for catching on the worker's shaped steel 102, consequently, V type trip 103's opening distance will be less than the long limit of rectangle hole 109 on the one hand, be convenient for V type trip 103 stretch into in the rectangle hole 109, on the other hand V type trip 103's opening distance will be greater than the minor face of rectangle hole 109, so after V type trip 103 stretches into rectangle hole 109, rotatory stock 101 makes V type trip 103 rotatory, thereby catch on the worker's shaped steel 102, make it unable shake out from rectangle hole 109.
Preferably, the surface of the anchor rod 101 is uniformly provided with the burrs 110, and the burrs 110 are fish-bone type, as shown in fig. 4, so that the anchor rod 101 can be more firmly fixed in the slope 100.
The steel pipe 107 is welded between the adjacent tip of the anchor rod 101 one end that stretches out side slope 100, and the end connection of anchor rod 101 is in the same place through steel pipe 107, and the anchor rod 101 tip that stretches out side slope 100 upwards fixed connection baffle 108, baffle 108 can the lug weld in anchor rod 101 tip upper end, also can be connected with anchor rod 101 tip upper end through the bolt.
A plurality of vertical steel pipes 104 are inserted into the side lines of the lower end of the slope 100 corresponding to the upper anchor rods 101, and steel pipes 107 are connected between the vertical steel pipes 104 and the ends of the upward adjacent anchor rods 101.
Preferably, the upper end and the bottom end of the side slope 100 are both provided with waterproof grooves 105, and the distance between the waterproof grooves 105 and the side slope 100 is 1-2 meters; the slope 100 is provided with hardened cement surfaces 106 at both the upper and lower ends. The waterproof groove 105 can prevent water at the upper end of the side slope 100 from flowing to the side slope 100 on one hand, and can prevent rainwater flowing down along the side slope 100 in rainy days from being accumulated at the bottom end of the side slope 100 to cause certain potential safety hazards on the other hand. Meanwhile, the hardened cement surface 106 can also protect the edge of the slope 100 to a certain extent.
The working principle is as follows: according to the structure, when the anchor rod 101 is inserted into an anchor rod hole, the V-shaped clamping hook 103 penetrates through the I-shaped steel 102 along the long edge of the rectangular hole 109 of the I-shaped steel 102, the anchor rod 101 is rotated by 90 degrees at the moment, then the anchor rod 101 is pulled to ensure that the anchor rod 101 and the I-shaped steel 102 are clamped together, and then expansion mortar is poured into the anchor rod hole. The arrangement of the burrs 110 on the anchor rod 101 and the pouring of the expansion mortar enable the anchor rod 101 to be firmly fastened in the slope 100 and finally form an integrated structure with the I-shaped steel 102, and the stability of the whole structure is improved. The anchor rods 101 are also connected to each other by the steel pipes 107. Simultaneously, pack the cured layer in the space between baffle 108 and side slope 100, the cured layer can be the concrete, and vertical steel pipe 104 passes through steel pipe 107 to be connected with stock 101 and fixes together, also can make side slope 100 and its bottom integrated into one piece for overall structure is more firm.
