Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arch-type shelter construction device for constructing an arch-type shelter mainly for roads, railways, etc., which is constructed in preparation for avalanches and landslides.

[0002]

2. Description of the Related Art Generally, a shelter may be constructed on a road or railway running in a mountainous area in preparation for an avalanche or a landslide, but most of them are constructed by cast-in-place concrete.

[0003]

However, a shelter made of cast-in-place concrete requires a large amount of manpower and construction materials, and it not only complicates the on-site work but also prolongs the construction period. .

The present invention has been made to solve the above problems, and an object of the present invention is to provide an arch-type shelter construction apparatus that enables labor-saving construction and a significant reduction in construction period.

[0005]

An arch-type shelter construction apparatus according to the present invention comprises a crawler crane which travels in a continuous direction of the arch-type shelter to suspend a segment, a work scaffold capable of moving up and down and laterally, And a guide roller that slides on a guide rail attached to the segment to prevent shaking and the like during work and running, and runs in the continuous direction of the arched shelter to temporarily support the segment from below and the segment A support cart for working on the inner side, and a guide roller for sliding along the side of the segment to prevent shaking during work and running, and running in the continuous direction of the arch-shaped shelter to outside the segment And a work carriage for carrying out the work.

[0006]

1 to 7 show an embodiment of an arch-type shelter construction apparatus according to the present invention. In the drawings, reference numeral 1 is a segment 2 for constructing an arch-type shelter.
A crawler crane for suspending and suspending the suspended segment 2 on the road 3 temporarily supports the suspended segment 2 from below and at the inner side of the segment 2, for example, the segment 2,2.
A support carriage for performing work such as tightening bolts for joining the two, and a work carriage 5 for performing work on the outer side of the segment 2.

The support truck 4 is provided on both sides of the road 3 with wheels 8,8 sliding on rails 7,7 on foundations 6,6 formed along the road 3 and inside the segment 2. The guide rails 9 and 9 are attached to the guide rails 10 and 10, and the work scaffold 11 and the like for performing the work on the inner side of the segment 2 are provided.

The guide rails 9 and the guide rollers 10 are attached to prevent the support carriage 4 from swaying or the like to travel safely and to prevent the support dolly 4 from swaying during work. The work platform 11 is supported by a lifting jack 12 so that it can be laterally moved freely left and right according to the work place and can be freely raised and lowered according to the work place height.

The work trolley 5 carries out the work of the wheels 8,8 running on the left and right foundations 6,6, the guide rollers 13,13 sliding on the side of the suspended segment 2 and the outer part of the segment 2. It is configured with a work scaffolding 14 and the like.

The guide rollers 13 and 13 are mounted to allow the work carriage 5 to travel safely and to prevent the work carriage 5 from swinging during work.

Next, a method for constructing an arch-type shelter by the arch-type shelter constructing apparatus according to the present invention will be described step by step.

(1) First, before suspending the segment 2, the foundations 6, 6 for erecting the segment 2 along the road 3 on both sides of the road 3 are constructed by reinforced concrete (see FIG. 6).

A recess 15 is formed in the foundation 6 so that the column base of the segment 2 can be set up, and a positioning member 16 made of an angle member or the like is used for positioning the column base of the segment 2 at the bottom of the recess 15. Attached along the road 3,
Apply level adjustment mortar 17 to adjust the height of segment 2 (see FIG. 7).

Further, a lower fixing bolt 18 for fixing the column base of the segment 2 is horizontally provided inside the recess 15 (see FIG. 7). The lower fixing bolt 18 is projected by dividing it into a plurality of pieces per one segment 2, and is also projected by being screwed into, for example, an insert nut embedded in the concrete of the foundation 6 so as to have a protruding length. To be freely adjustable (see FIG. 7).

Further, rails 7,7 are laid on the left and right foundations 6,6, and the support carriage 4 is installed on the rails 7,7. Also,
The work cart 5 is installed on the outside thereof. Further, the crawler crane 1 is installed on the road 3.

The support carriage 4 and the work carriage 5 may be constructed so that they can be driven by their own power by being loaded with power, but as shown in the figure, they may be simple ones that are pulled by a winch 19 to travel.

(2) Next, the crawler crane 1 hangs the segments 2 one by one and hangs them on both sides of the road 3, and the support truck 4 temporarily supports them from below.

At this time, the column base of the segment 2 is erected on the level adjusting mortar 17 in the recess 15 of the foundation 6, and the upper end thereof is abutted with the opposing segment 2 just above the road 3.

(3) Next, the upper ends of the left and right segments 2 are integrally joined by the upper connecting bolts 20, and the column bases are fixed by being strongly sandwiched between the lower fixing bolts 18 and the positioning member 16 from both sides. To do. An elastic sealing material (not shown) for stopping water is interposed between the abutting portions of the left and right segments 2,2.

(4) Next, attach this segment 2 to the front side of the segment 2 that has just been suspended, and suspend a new segment 2 in exactly the same manner as the work of
The already installed segment 2 is integrally bolted with an elastic sealing material (not shown) for stopping water. The tightening of the bolts at that time is performed on the work platform of the support carriage 4 and the work carriage 5.

The recess 15 may be filled with concrete or the like after the segment 2 is erected.

In the same manner, the suspension of the segment 2 and the tightening of the bolts are alternately repeated in the same manner to construct the entire length of the arch-shaped tunnel, and after the construction is completed, the crawler crane 1, the supporting carriage 4, and the working carriage 5 are carried out. Remove the equipment.

In the embodiment, the construction method of the arch-type shelter installed on the road has been described, but it can be applied to the construction of the railway shelter, and the construction of the tunnel for the waterway constructed under the ground surface. Can also be applied to.

Needless to say, both concrete and steel segments can be used as the segment 2.

[0025]

The arch shelter construction apparatus according to the present invention is configured as described above, and is a crawler crane that travels in the continuous direction of the arch shelter to suspend the segments and a work that can be moved vertically and horizontally. Scaffolding,
And a guide roller that slides on a guide rail attached to the segment to prevent shaking and the like during work and running, and runs in the continuous direction of the arched shelter to temporarily support the segment from below. It is equipped with a support carriage that works on the inside of the segment and a guide roller that slides on the side of the segment to prevent shaking during work and running, and runs in the continuous direction of the arched shelter to outside the segment. Since it is configured with a work trolley for performing part work, hanging of the segment,
There is an effect that the temporary support of the segments and the joining of the segments can be constructed very safely and efficiently without waste in the process.
