Description

Tunnel inverted arch filling drainage tank processing die

Technical Field

The utility model belongs to the technical field of tunnel drainage channels, and particularly relates to a tunnel inverted arch filling drainage channel processing die.

Background

Because the inverted arch of the tunnel is different from the concrete cast on the side wall of the tunnel in terms of the marks, inverted arch concrete is cast after being separated by a filling template, the inverted arch concrete which is just cast is manually extruded by adopting a semicircular groove tool, and then the groove tool is taken out before the concrete is not completely solidified, so that a drainage groove is formed in the inverted arch area near the left side and the right side.

Disclosure of Invention

The utility model aims to provide a tunnel inverted arch filling drainage tank processing die which is smooth in line type and consistent in depth, and solves the problems that the depth of a drainage tank is different, the line type is not smooth and corners are missing due to the fact that inverted arch concrete which is just poured is manually extruded by adopting a semicircular tank and then the tank is taken out to form the drainage tank before the concrete is not solidified completely.

The technical scheme adopted by the utility model is as follows: the utility model provides a drainage tank mold processing is filled to tunnel inverted arch, includes the top surface and fills the face flush fill template, along the base that fills template lateral wall longitudinal interval set up, with the fixed arm of base one-to-one, the drainage tank mold of all fixed arms of longitudinal joint and along the bracing piece that fills template lateral wall longitudinal interval set up, fill the template and separate tunnel inverted arch and tunnel side wall region, base level bottom surface and fill template lateral wall and form little triangle supporting space, the fixed arm is "n" type after upwards exposing the face along filling template lateral wall from the base top and buckles to flush with the face of filling, drainage tank mold top surface flushes with the face of filling, the one end that the template was kept away from to the bracing piece supports the tunnel side wall and forms big triangle supporting space, combines little triangle supporting space to support tunnel inverted arch filling drainage tank mold processing jointly.

As the preference of above-mentioned scheme, water drainage tank mould transversal personally submits the trapezoid structure, and big end down's structure is convenient takes out, also can not collide the corner shape of influence, water drainage tank mould adopts 8mm ~ 10mm thick steel sheet seamless concatenation to form, reasonable in design, the structure is inseparable.

Further preferably, the fixing arm is made of flat steel with the width of 100-110 mm and the thickness of 12-14 mm, and the material selection range is reasonable; the base adopts double-spliced I-steel, and is longitudinally arranged on the outer side wall of the filling template at intervals of 0.8 m-1.2 m, so that the supporting stability of the drainage channel along the longitudinal direction of the tunnel is ensured.

Further preferably, the base, the fixing arm and the filling template are welded and connected, the end part of the fixing arm and the drainage tank mold are welded and connected, welding is firm, and structural connection is tight.

Further preferably, the support rod adopts a screw-nut mechanism to realize length adjustment of the rod body, so that real-time adjustment is performed according to the distance between the tunnel side walls, and the smoothness of the line type of the filling module is ensured.

The utility model has the beneficial effects that:

(1) Compared with the mode that the inverted arch concrete which is just poured is manually extruded by adopting the semicircular groove tool, then the groove tool is taken out to form a drainage groove before the concrete is not completely solidified, fixing arms which are in one-to-one correspondence with bases which are arranged at intervals longitudinally along the outer side wall of the filling template are adopted, the fixing arms are bent to be flush with the filling surface after being upwards exposed out of the filling surface along the outer side wall of the filling template from the top of the bases, and finally the drainage groove mold is longitudinally connected with all the fixing arms, so that the consistency of the depth of the drainage groove, the smoothness of the line type and the integrity of corners can be ensured.

(2) The horizontal bottom surface of base forms little triangle with filling the template lateral wall and supports the space, and the one end that the filling template was kept away from to the bracing piece supports the tunnel side wall and forms big triangle and support the space, combines little triangle to support the tunnel inverted arch to fill water drainage tank mold processing together, consequently need not extra manual auxiliary support, only need settle the position of filling the template, just can realize independently supporting, and whole design conception is ingenious, and the practical condition of tangent tunnel side wall, the structure independently supports stability height.

In conclusion, the structure has the advantages of ensuring consistent depth of the drainage groove, smooth line type, complete corners, high independent structural support stability and the like.

Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in fig. 1, a tunnel inverted arch filling drainage tank processing mold is composed of a filling template 1 with a top surface flush with a filling surface, bases 2 arranged at intervals longitudinally along the outer side wall of the filling template 1, fixing arms 3 in one-to-one correspondence with the bases 2, a drainage tank mold 4 longitudinally connected with all the fixing arms 3, and supporting rods 5 arranged at intervals longitudinally along the outer side wall of the filling template 1.

The filling pattern 1 separates the tunnel invert and the tunnel sidewall area.

The base 2 is preferably made of double-spliced I-steel, and is longitudinally arranged on the outer side wall of the filling template 1 at intervals of 0.8 m-1.2 m.

The horizontal bottom surface of the base 2 and the outer side wall of the filling template 1 form a small triangular supporting space.

The fixing arm 3 is preferably made of flat steel with a width of 100mm to 110mm and a thickness of 12mm to 14 mm.

The fixing arm 3 is bent in an n-shape until being flush with the filling surface after being exposed upwards along the outer side wall of the filling template 1 from the top of the base 2.

The top surface of the drain tank mold 4 is flush with the filling surface.

The cross section of the drainage groove die 4 is of an inverted trapezoid structure, and the drainage groove die 4 is formed by seamless splicing of 8-10 mm thick steel plates.

And one end of the supporting rod 5, which is far away from the filling template 1, is propped against the side wall of the tunnel to form a large triangular supporting space, and the small triangular supporting space is combined to jointly support the processing mould of the inverted arch filling drainage channel of the tunnel.

The base 2, the fixed arm 3 and the filling template 1 are welded and connected, and the end part of the fixed arm 3 and the drain tank mold 4 are welded and connected.

The support rod 5 preferably adopts a screw-nut mechanism to realize the length adjustment of the rod body.

The filling template 1 is initially fixed at a designed position so as to separate a tunnel vault from a tunnel side wall, and then the length of the supporting rod 5 is finely adjusted so that the other end of the supporting rod 5 far away from the filling template 1 abuts against the tunnel side wall.

And a small triangular supporting space is formed by combining the horizontal bottom surface of the base 2 and the outer side wall of the filling template 1, so that the position stability of the filling template is ensured.

Meanwhile, the drainage tank mold 4 can also ensure the constant position of the filling template 1 through the fixing arm 3, so that the linear smoothness of the drainage tank mold 4 is ensured, and the drainage tank mold extends longitudinally along a tunnel.

And finally, vibrating and pouring concrete to the tunnel inverted arch area, and taking out the filling template 1 before the concrete is solidified, so that the drainage channel mold 4 is taken out at the same time, and the drainage channel in the tunnel inverted arch area is manufactured.
