Description
Technical Field
The invention relates to an engineering construction tool, in particular to a tunnel advance small guide pipe positioning tool.
Background
In the past, the construction of a tunnel (tunnel) advance small guide pipe is generally carried out by field visual inspection or ruler quantity of constructors for angle control, and the angle deviation is larger. Particularly in weak surrounding rock sections, if the angles of the leading small guide pipes of the same ring are inconsistent (larger deviation from the design angle), a 'shed frame' effect cannot be formed, and sliding collapse is easy to cause, so that the problem can be solved by designing an angle positioning device of the leading small guide pipes.
Chinese patent CN 207377581U discloses a leading small pipe location frock, and it is through fixed buckle and bracket as locating platform on the tunnel steelframe, and its bracket is semicircular inclined channel, can regard the bracket as the benchmark and throw into the drilling rod, and this frock adheres to the tunnel steelframe, utilizes the steelframe as walking track, removes in a flexible way, easy operation, has solved the problem that the angle control is difficult is implemented to the leading small pipe of tunnel. But this structure has two problems: 1. the fixing mode has certain defects, the fixture is mainly used for fixing the clamping plate on the lower edge of the steel frame by two screws, and meanwhile, the upper edge of the steel frame is buckled by the buckling plate, so that the stability of the structure is insufficient, and the buckling plate and the clamping plate can deform. 2. The bracket is a semicircular groove, so that the bracket can only support the drill rod for the next time, the constraint is lacking above the drill rod, a certain degree of deflection can occur in the drilling process, and accurate angle positioning cannot be realized. Both of these problems may affect the penetration angle of the drill rod, and if created at the same time, may further enlarge the angle error of the drill rod.
Disclosure of Invention
The invention aims to solve the technical problems that: aiming at the problem of inaccurate positioning of the existing small catheter positioning tool, the positioning tool with better stability and accuracy is provided.
The technical scheme of the invention is as follows: an angle positioning device for an advanced small catheter comprises a positioning seat, wherein the positioning seat is of a box-type structure, a guide tube is arranged on a front panel of the positioning seat, a hole is formed in a rear panel of the positioning seat, and the guide tube has an inclination angle.
Mounting holes with the same cross-sectional shape as the tunnel steel frame are formed in the left side and the right side of the positioning seat.
The positioning seat is composed of two clamping plates, and the lower ends of the two clamping plates are connected through a hinged support.
The top of the positioning seat is provided with a movable buckle for locking the upper ends of the two clamping plates.
Or alternatively: the locating seat is composed of two clamping plates, the lower ends of the two clamping plates are hinged through the hinged support, two vertical limiting plates are respectively arranged on two sides of the two clamping plates, and the limiting plates are matched with the middle part of the tunnel steel frame.
Two clamping plates are perforated and bolts are arranged between the two clamping plates.
The invention has the beneficial effects that: the angle positioning device of the advance small conduit adopts a buckle fixing and sleeve guiding structure, before the advance small conduit is applied, the movable buckle is firstly broken off to enable the positioning seat to be overturned and separated, then the positioning seat is mounted on a tunnel (tunnel) steel frame, and the movable buckle can be locked for use. And (3) drilling by adopting an air drill, penetrating a drill bit into a drilling directional sleeve, and starting a drilling machine to drill to a designed depth. After one hole site is bored, the movable buckle is unlocked to enable the whole device to move to the next hole site along a tunnel (tunnel) steel frame for continuous construction, and the device is convenient to convert and easy to operate.
The invention successfully solves the technical problem of directional control of the small conduit design angle in the advance support process of the tunnel (tunnel). The positioning device is reasonable in design and can accurately position the drilling angle of the small guide pipe.

Detailed Description
Example 1: the angle positioning device of the advance small guide pipe adopts a positioning seat fixing and directional sleeve guiding structure, and consists of a positioning seat 1, a hinged seat 2, a movable buckle 3 and a guiding pipe 4 for drilling and directional drilling, wherein the positioning seat 1 is box-shaped, can be installed and fixed on a tunnel (tunnel) steel frame, and can move along the annular direction of the steel frame, and the steel frame in the embodiment is I-shaped channel steel. The lower surface portion of the positioning seat 1 is provided with a hinged seat 2, two clamping plates are connected to the hinged seat 2, the positioning seat 1 is formed after the two clamping plates are closed, the upper surface of the positioning seat 1 is provided with a movable buckle 3, the movable buckle 3 can realize quick locking and quick unlocking of the two clamping plates, slotted holes with the same cross section shape as the steel frame are formed in the left side and the right side of the two clamping plates, and the slotted holes are matched with the steel frame. The clamping plate at the front side of the positioning seat 1 is provided with a guide tube 4 for drilling and orientation, and the guide tube 4 has a certain inclination angle (5-45 degrees and is determined according to design requirements). The guide pipe 4 can make the drill rod directionally drill, so as to realize the angle positioning of the advance small guide pipe. The clamping plate at the rear side of the positioning seat 1 is provided with a through hole.
The operation steps used are: 1. before the leading small catheter is applied, the movable buckle 3 is unlocked firstly, so that the positioning seat 1 is turned over and separated; 2. installing the positioning seat 1 to a design position on a tunnel (tunnel) steel frame, and locking the movable buckle 3; 3. drilling by adopting an air drill, penetrating a drill bit into the guide pipe 4, and starting the drill to the designed depth; 4. after the current hole site is drilled, the movable buckle 3 is unlocked, and the positioning device is moved to the next hole site along the steel frame to continue construction. Thus completing one cycle of directional drilling of the advance small guide pipe.
Example 2: the positioning seat 1 in the embodiment is formed by hinging two clamping plates through the hinged seat 2, two vertical limiting plates are respectively arranged on two sides of the two clamping plates, the shape of the limiting plates is identical with that of the middle part of the channel steel, and the middle part of the channel steel of the tunnel steel frame can be clamped through the limiting plates. And punching holes on the two clamping plates, installing bolts, and locking and opening the clamping plates by using the bolts. One of the clamping plates is used as a front panel of the positioning seat 1 and is provided with a guide pipe 4, and the other clamping plate is perforated at a position corresponding to the axial direction of the guide pipe.
