Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the utility model discloses a soil nail locator, soil nail locator is whole to be the cylinder and then has top surface, lower bottom surface and be used for the lateral wall face of laminating mutually with the pore wall of reinforcing hole.
The soil nail positioner is provided with a soil nail through hole 1, a grouting through hole 2 and a grout returning through hole 3 which are communicated with the upper top surface and the lower bottom surface.
The soil nail through hole 1 is arranged along the axis of the soil nail positioner and is used for enabling the soil nail to penetrate through, and the aperture of the soil nail through hole 1 is matched with the soil nail. When the soil nails pass through the soil nail through holes 1, the soil nail through holes 11 provide support for the soil nails.
The grouting through holes 2 and the grout returning through holes 3 are all provided with four and evenly distributed around the axis of the soil nail positioner. The grouting through holes 2 and the grout returning through holes 3 are alternately arranged. The grouting through hole 2 is circular and is punched through the side wall surface of the soil nail positioner. The slurry return through hole 3 is in a waist-shaped hole shape and extends along the radial direction of the soil nail positioner, and the width of the slurry return through hole 3 is gradually increased along with the distance from the soil nail through hole 1.
The grouting through hole 2 is used for the grouting pipe to pass through. After the grouting pipe is used for grouting into the reinforcing hole, concrete can overflow from the grouting through hole 2 and the grout returning through hole 3 until the reinforcing hole is filled. A gap is reserved between the grouting through hole 2 and the grouting pipe, the grout return through hole 3 is in a waist-shaped hole shape and extends along the radial direction of the soil nail positioner, and the width of the grout return through hole 3 is gradually increased along with the distance from the soil nail through hole 1. The arrangement avoids the occurrence of a particularly thin position between the grouting through hole 2 and the grout returning through hole 3, the weight reducing effect can be fully exerted, and the overflow flow of the concrete from the grout returning through hole 3 can be larger.
The soil nail positioner is provided with an opening 4, and the opening 4 is communicated with the soil nail through hole 1 and one of the grouting through holes 2.
The soil nail positioner is provided with two pairs of first bulges 5, and the two pairs of first bulges 5 are respectively positioned on the upper top surface and the lower bottom surface and extend out towards two directions of the axis of the soil nail positioner. Two first protrusions 5 located on the same side are located on both sides of the opening 4, respectively.
The first protruding parts 5 are provided with through holes, bolts 7 penetrate through the two through holes on the two first protruding parts 5, and the bolts 7 are connected with nuts 72 in a matching mode. The nut 72 is screwed to deform the soil nail positioner, and the two first protruding parts 5 move towards each other, so that the distance between the openings 4 is reduced, the soil nail through hole 1 is contracted, and the soil nail through hole 1 can clamp the soil nail positioned in the soil nail through hole, so that the relative movement of the soil nail and the soil nail positioner is limited.
The soil nail locator still is provided with two second bulge 6, and two second bulge 6 are located top surface and lower bottom surface respectively, and two second bulge 6 stretch out towards two directions of the axis of soil nail locator along the edge of soil nail through-hole 1, and second bulge 6 covers the edge of soil nail through-hole 1 completely. The second projecting portions 6 projecting toward the same side are integrally connected to the corresponding two first projecting portions 5. The second protruding part 6 can increase the contact area of the soil nail positioner and the soil nail, so that the soil nail is fixed more stably.
The specific implementation principle of the embodiment is as follows: the soil nails penetrate through the soil nail through holes 1, and the soil nail positioner is used for clamping the soil nails by using the bolts 7 and the nuts 72. The soil nail positioner is used for being placed in a reinforcing hole formed in a side slope or a hillside of a foundation pit, and the soil nail positioner can provide support for soil nails. And (3) penetrating the grouting pipe through the grouting through hole 2 to perform grouting in the reinforcing hole, and enabling the concrete to continuously flow through the grouting through hole and the grout returning through hole 3 until the reinforcing hole is filled with the concrete. The use of the soil nail positioner can shorten the time for fixing the soil nails in the reinforcing holes, and the fixed position is accurate, thereby saving the labor cost.
The soil nail positioner can be formed by injection molding of hard plastics, and is convenient for batch production.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
