Embodiment Construction

[0072] This embodiment is a kind of soil ruins reinforced anchor rod, as attached figure 1 As shown in , it includes a plurality of connecting screw rods 1 , a multi-section bakelite rod 2 , a plurality of resistance bars 3 and a bakelite nut 4 . Among them: each bakelite rod 2 is equipped with a connecting screw 1 on one end face, and the center of the other end face of each bakelite rod has a blind hole matched with the connecting screw 1. When in use, each section of bakelite rod 2 is passed through The connecting screws are joined end to end to form a reinforced anchor. Two sets of resistance rod mounting holes are distributed on the circumferential surface of the reinforced anchor rod through the body of the reinforced anchor rod, and are respectively used for installing the first group of resistance rods 3 and the second group of resistance rods 5 . The plurality of resistance bars are divided into two groups, installed in the installation holes of the resistance bars, ...

Abstract

The invention discloses an earthen ruin reinforcing anchor rod and a design method of the earthen ruin reinforcing anchor rod. According to the structure, the anchor rod comprises multiple connecting threaded rods, multiple sections of bakelite rods, multiple resistance bars and multiple bakelite nuts, and a traditional single bar-shaped design concept is abandoned. The resistance bars intersect by 90 degrees and are evenly distributed on the bakelite rods, so that the formed resistance structure is more beneficial to reinforcement of anchoring force. According to the anchoring length, the bakelite rods are connected into the anchor rod through the connecting threaded rods, so that the anchor rod is suitable for anchoring operation of ruin soil bodies of various lengths. The bakelite rods are selected as an anchor rod material so that the anchor rod can be applied to arid, semi-arid and damp earthen ruin reinforcing environments. Structure parameters of the anchor rod are determined according to the conditions of earthen ruins and different earth conditions determine the anchor rods with different parameters. By the adoption of the method, the proper anchor rod can be designed according to the specific conditions of different earthen ruins.

Description

technical field [0001] The invention relates to the field of protection of ancient earth relics, in particular to an earth relic reinforcing anchor and a design method thereof. Background technique [0002] There are many ancient earthen building sites left in Northwest my country, such as the Hanguangmen earthen site of the Tang Emperor's city wall in Xi'an, Shaanxi, the Dadiwan human settlement site in Qin'an County, Gansu, and the Western Xia king's mausoleum earthen site. These earthen building sites have a long history, and some have been listed as world cultural heritage, with high archaeological and historical value. Due to the long history, the soil of ancient earthen sites is loose, low in strength, and large in porosity, and most of them have severe cracks, which eventually lead to collapse and damage. Soil's physical and mechanical properties and construction techniques determine the vulnerability of earthen sites, so many factors need to be considered comprehens...
