AI Technical Summary
In the Xigeda Formation, the vent holes of the drill bit and the ventilation holes inside the drill rod were blocked by soft plastic Xigeda clay rock during drilling, which prevented high-pressure air from being delivered and drill cuttings from being discharged from the hole, making hole formation difficult and grouting impossible. In addition, traditional mortar anchors have low pull-out force, making construction difficult and prolonging the construction period.
An anchor bolt body with oblique threads and hexagonal connectors are used. They are directly installed using a hand drill or other tools. The anchor bolt tip assists in drilling into the strata. The oblique threads cooperate with the soft plastic clay rock of the strata to achieve smooth hole formation and improve pull-out force.
Successful drilling was achieved in the Xigeda Formation, ensuring construction quality, improving the pull-out force of anchor bolts, simplifying the construction process, and shortening the construction period.

Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of anchor rod suitable for Xigeda group stratum construction, belong to anchor rod technical field. BACKGROUND
[0002] Anchor rod construction is applied very much in engineering construction field, and most tunnels and slopes use mortar anchor rod, usually first using hand drill to drive drill bit to drill, then using cement mortar to fill into hole, finally inserting mortar anchor rod, and after cement mortar solidifies, mortar anchor rod is fixed. However, Xigeda group stratum has special engineering properties, and the air hole of drill bit and the air hole in drill rod are blocked by soft plastic Xigeda clay rock when drilling, high-pressure air cannot be sent in, and drill slag in hole cannot be smoothly discharged, leading to drilling cannot continue, and hole forming is particularly difficult, thus leading to the problem that grouting cannot be carried out. Therefore, using traditional mortar anchor rod in Xigeda group stratum often has very small pulling force and cannot meet design requirements, and construction is difficult and delays construction period. How to reasonably construct anchor rod in Xigeda group stratum, which can facilitate construction, ensure construction quality, and make anchor rod play its due role, is an important problem that must be considered in construction process. SUMMARY
[0003] The utility model aims at overcoming the shortcomings of prior art, and provides a kind of anchor rod suitable for Xigeda group stratum construction, which is convenient for hole forming, ensures construction quality, facilitates construction, and makes construction operable.
[0004] The technical scheme of the utility model one kind suitable for Xigeda group stratum construction's anchor rod is as follows: including anchor rod main part, the anchor rod main part lower head is provided with conical anchor rod tip, and inclined thread is arranged on the outer wall of anchor rod main part and anchor rod tip, and connector is arranged on the upper head of anchor rod main part.
[0005] Further, the connector is hexagonal.
[0006] Further, the pitch P of the inclined thread is 20-30mm.
[0007] Further, the height H of the inclined thread is 10-20mm.
[0008] Further, the thickness T of the inclined thread is 2-5mm.
[0009] The utility model one kind suitable for Xigeda group stratum construction's anchor rod has the beneficial effects that the engineering property characteristics of Xigeda group stratum are fully considered, the anchor rod main part with inclined thread is used, the hexagonal connector is directly connected with hand drill or other construction tools for installation, hole forming is convenient, construction quality is ensured, construction is facilitated, construction is operable, a new idea is provided for tunnel and slope support in Xigeda group stratum area, and has certain popularization and application prospect.

[0013] This utility model relates to an anchor bolt suitable for construction in the Xigeda Formation, such as... Figure 1 — Figure 3 As shown, it includes an anchor bolt body 1, with a tapered anchor bolt tip 2 at the lower end of the anchor bolt body 1, and oblique threads 3 on the outer walls of the anchor bolt body 1 and the anchor bolt tip 2. A connector 4 is provided at the upper end of the anchor bolt body 1.
[0014] Furthermore, the connector 4 is hexagonal.
[0015] Furthermore, the pitch P of the herniated thread 3 is 20-30 mm.
[0016] Furthermore, the height H of the herniated thread 3 is 10-20mm.
[0017] Furthermore, the thickness T of the herniated thread 3 is 2-5 mm.
[0018] This utility model discloses an anchor rod suitable for construction in the Xigeda Formation. In use, the hexagonal connector 4 on the main body 1 is first connected to a hand drill or other construction tool, essentially using the main body 1 as a drill bit. The anchor tip 4 is aligned with the construction location, and the hand drill is started to rotate the anchor body 2, thereby rotating the inclined thread 3. The anchor tip 4 assists in drilling into the soil. After the main body 1 is drilled into place, the connector 4 is removed from the hand drill or other construction tool. The inclined thread 3 on its outer wall engages with the soft plastic Xigeda clay rock in the Xigeda Formation (similar to the working principle of a screw), allowing the pull-out force to meet design requirements, thus drilling the entire anchor rod into the soil to achieve the designed anchor rod function. This solution presents an anchor bolt suitable for construction in the Xigeda Formation. It fully considers the engineering characteristics of the Xigeda Formation and adopts an anchor bolt body 1 with inclined threads 3. It is directly connected and installed with a hand drill or other construction tools using a hexagonal connector 4. This facilitates hole formation, ensures construction quality, and makes construction easy and operable. It provides a new approach for tunnel and slope support in the Xigeda Formation area and has certain prospects for promotion and application.
