Abstract
The utility model relates to a spiral stock of special non - grout glass fiber in soil ruins, an organic whole is become to the pole head of the spiral stock of glass fiber, and body of rod top spin is threaded. The pole head of the spiral stock of glass fiber is the hilllock hilltop or for the close crop or for the coiled hair, has the cross to detain the line on the pole head surface, and the pole tail is 15-30 closed angles, the utility model discloses a ruins body is got into to the spiral glass fibre bar body to an effect that frictional resistance that is stronger builds the ruins protection in the civil engineering and has exert actively in consolidating the engineering practice is provided.
Description
Technical field
The utility model relates to earthen ruins protection test research and protection field of reinforcement, belongs to a kind of glass fiber spiral anchoring-bolt that earthen ruins small blocks suspension area reinforces, especially more convenient practicality in wet environment.Also the association areas such as geotechnical engineering can be applied to.
Background technology
The Xinjiang in NORTHWEST CHINA area, Gansu, the many ancient soil Architecture sites of the domestic remnants in Ningxia and Shaanxi, northern Great Wall of wriggling, the city, pass on vast Gobi desert, northwest, beacon flint, the friendship river in Xinjiang, Gao Chang, Lou Lan, Niya Ruins, be upper and lower Wan Nian, ten thousand li in length and breadth, spread all over China.These earth construction sites are with a long history, and what have is classified as world cultural heritage, have very high archaeology and historical value, but over the past thousands of years, serious wind erosion and heavy showers destroy, and large quantities of earthen ruins is under root undercutting, and large area is caved in and even be suffer from destructive destruction.But, traditional grouted anchor bar is in the body reinforcing process of ruins, because the difference of slurry material, proportioning and environment affects its anchored force comparatively significantly, and affect the compatibility of ruins body, especially its intensity of grouted anchor bar in wet condition improve speed compared with slow, slip casting difficulty large, slurries be difficult to solidify wait difficult.Therefore, research and development are a kind of compatible strong, it is little to intervene, intensity improves very fast, and the anchor pole being applicable to the anchoring of particular surroundings earthen ruins is very urgent task for protection earthen ruins.
Earth construction site is one of early stage typical traditional architecture construction mode of China, it is due to sheerly soil property building, under long-term nature and human factor impact, ruins body highlights dissimilar disease, especially under external force, ruins body grows crack, and it is one of main Types of ruins body fall damage that rainwater pours into corrosion function.Often through the anchor rod anchored resistance to overturning improving ruins body, for independent block provides certain support and pulling force, ordinary circumstance all adopts grouting formula anchor pole.But, ruins bulk environment, material and the build process anchor pole that often demand is dissimilar, for this reason, a kind of anchored force and supporting role are reliably provided, strong for compatibility, intervene little, intensity and improve very fast, the anchor pole being suitable for the ruins body anchorage support power of relative humidity environment is necessary.
Summary of the invention
In view of above-mentioned, the purpose of this utility model is to provide a kind of earthen ruins special non-grouting glass fiber spiral anchoring-bolt, reinforce in use procedure to overcome existing grouting formula anchor pole at earthen ruins, poor compatibility, anchored force is because of grouting agent, proportioning difference, comparatively large on the ruins bodies impact of wet environment, intensity is lower, and inapplicable with the reinforcing of relative humidity environment earthen ruins etc. defect.
The purpose of this utility model is achieved in that
The special non-grouting glass fiber spiral anchoring-bolt of a kind of earthen ruins, is characterized in that the bar head of glass fiber spiral anchoring-bolt becames one, the body of rod is rotary with screw thread.The hilltop, Gan Touwei hilllock of glass fiber spiral anchoring-bolt or be close crop or be coiled hair, bar head has cross buckle line, bar tail is 15 ° ~ 30 ° wedge angles.
the beneficial effect of advantage of the present utility model and generation is:
(1) warded off out single conventional grout formula Soil Anchor Design theory, got into mode by spiral and body of rod frictional force is effectively provided, greatly improve anchor-holding force of anchor bolt.
(2) conveniently, easily install.Get into the spiral glass fiber body of rod by cross buckle line on swingle head, increase the frictional force of the body of rod and ruins body, improve rapidly the bulk strength of ruins body, instead of conventional grout bonding mode, avoid wet environment slurries to be not easy the difficulty of solidifying.
(3) this rock-bolt length is no more than 1m, diameter be not more than 20mm, the spiral expansion anchor rod of non-grouting, has good pull resistance and corrosion resistance.
((4) the utility model anchor structure is simple, and easy for installation, cost is low, simplifies construction technology, reinforces in earth construction site suspension area, Arid and semiarid area, and wet environment ruins body reinforces the scene that is widely used.
Accompanying drawing explanation
Fig. 1 is the utility model sectional schematic diagram;
Fig. 2 is Fig. 1 bar head schematic diagram;
Fig. 3 is Fig. 2 bar head surface cross buckle line schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described again:
As Figure 1-3, the special non-grouting glass fiber spiral anchoring-bolt of a kind of earthen ruins, the bar head 2 of glass fiber spiral anchoring-bolt 1 becames one, and the body of rod is rotary with screw thread.The bar head 2 of the spiral glass fiber body of rod 1 is close crop, and bar head 2 has cross buckle line 3 on the surface, and bar tail is the wedge angle of 25 °.
The spiral expansion anchor rod of non-grouting that the utility model provides, its anchored force is determined according to the condition of earthen ruins.Anchor-holding force of anchor bolt all considers the influence factor such as moisture content, void ratio, soil condition in the body of each ruins.Its operation sequence is as follows:
(1) manual pore-forming, by being less than the drill bit pore-forming of bolt diameter, gets into ruins body by directly spiral for non-grouting formula glass fiber anchor pole, is improved the resistance to overturning of ruins body by anchor-holding force of anchor bolt.
(2) or adopt not pore-forming, spiral fiberglass pole is directly screwed in and gets into ruins body.
(3) cap holes, and do surfacing.
Screw in fiberglass pole, good endurance in clayey ancient site body, securely clayey ancient site is became one, improve the end anchorage power of anchor pole, for protection ancient soil Architecture site has played effect.
Claims (1)
1. the special non-grouting glass fiber spiral anchoring-bolt of earthen ruins, the bar head (2) of glass fiber spiral anchoring-bolt (1) becames one, the body of rod is rotary with screw thread, it is characterized in that the bar head (2) of glass fiber spiral anchoring-bolt (1) is for the hilltop, hilllock or for close crop or for coiled hair, bar head (2) has cross buckle line (3), bar tail is 15 ° ~ 30 ° wedge angles.
