Description

Technical Field [0001] The present invention relates to a construction method for a sidewalk enlargement installation using an inclined retaining wall,

The present invention relates to an extended cargo structure installed on a slope which is difficult to install on a river side or a roadside, such as India or bicycle roads, and more particularly, to an extended cargo structure which is separated from the ground using a retaining wall So that the extension guide can be fixedly installed in the form of a bi-directional protrusion from the end of the retaining wall, thereby maximizing the usable area of the extended guide while allowing the simple and quick construction of the extended guide structure will be.

In general, a bridge means a facility where a vehicle or a person can cross the terrain with a high or low altitude such as a river, a stream or a valley. The bridge may be constructed in various ways depending on the surrounding environment, . ≪ / RTI >

Among these bridges, recently constructed bridges have been constructed with both sides of the roadway, but there is no built-in bridge that allows people to pass through the bridges built for the main purpose of vehicle movement.

In addition, as bicycles, which have been widely popularly used as eco-friendly transportation means as well as the development of leisure culture, have been popularly used, many bicycle roads have been installed in many places where bicycles can be safely ridden. In most bridges, Since the delivery can not be narrowed or changed, the bicycle road is inevitably temporarily disconnected at the bridge portion as described above.

Accordingly, Korean Patent Registration No. 432594 discloses that a rail is provided at both ends in the width direction of the bridge top plate, and a bridging bridge is installed outside the rail. The bridge bracket is installed at both sides or one end of the bridge top plate by a fastening means at a predetermined interval. The bridge bracket is welded to the base plate and extends in the width direction of the bridge top plate. A foot plate fixed on the beam bracket, and a pedestrian guardrail fastened and fixed to an outer upper end of the beam bracket.

In addition, the beam bracket is composed of an upper flange and a lower flange and a web so as to increase the structural characteristics.

Particularly, in addition to the side of a bridge and a road in the nearest vicinity, there is a slope such as a river side or a road side adjacent to the slope side to form a terrain which is difficult to construct an Indian or bicycle road. Extension India and Extension Device for slope such as Patent No. 10-1202609, Method of installing Extension Device for Slope such as Patent No. 10-1202608, respectively, have been enacted and registered.

These inclined extension devices or methods are provided with an extension guide by using a retaining wall to prevent slope and so on at a slope while separating slopes and roads. By using the top surface of the retaining wall or the front end surface of the retaining wall A cantilever beam in the form of a cantilever beam is fixed along the longitudinal direction of the retaining wall, a support pipe and a bottom material are fixed on the upper surface of the cantilever, and if necessary, India to be installed.

Accordingly, when the extension guide for the inclined land using the above-described retaining wall can not be installed on the ground, it can be easily and safely walked by the person or the bicycle by installing the extended guide separated upward from the ground by using the retaining wall .

However, since the extension guide using the existing retaining wall of the inclined land uses the upper surface or the side surface of the retaining wall to fix and extend the cantilever, it is necessary to install the extension guide in one side only, And the cantilever itself is highly weighted. Therefore, the use of excessive materials and the supplementary reinforcement and the reinforcement work are complicated by the safety design standard.

That is, in the case of the extended delivery using the cantilever type cantilever, the moment becomes larger toward the end of the cantilever, so that a considerable amount of stress will be continuously applied to the cantilever. When the pedestrian and the bicycle are concentrated, And the load between the retaining walls will be maximized. Accordingly, the cantilever-type cantilever can not be enlarged in size but can be installed only in a limited area according to the universal design standard. Thus, when the extension guide is completed by such a design standard, It is practically impossible to make an area sufficient for pedestrians to use.

In addition, due to the concentrated stress caused by the unloading, frequent breakage of the retaining wall joint or cantilever fixation occurs frequently. Therefore, it has to be checked and repaired and supplemented frequently. Due to the structural blind spot having such weakness, The excessive use of the cantilever connection and the excessive security and safety construction of the fixing part increases the amount of steel including the cantilever and increases the complexity of the work process and thus the construction period becomes very long and it is extremely uneconomical and inefficient .

SUMMARY OF THE INVENTION The present invention has been made to solve the problems as described above, and it is an object of the present invention to provide a support beam installation part by reinforcing a support beam installation part by machining a front end surface of a retaining wall facing a tilter of a slope and a slope, And the installation of the cross bar and the floor material and the railing are performed on the support beam,

It is possible to provide an extended guide for securing a maximum available area on the upper side of the retaining wall, and the support beams in the form of two arms can be more excellent in structural stability than the conventional cantilever beams, It is an object of the present invention to provide an extended delivery method using an inclined retaining wall which is capable of significantly reducing the amount of steel material and greatly improving the stability of construction by the support beam installation part.

According to an aspect of the present invention, there is provided a method of manufacturing a semiconductor device, the method including: a trenching process for a work groove formed on an upper portion of a slope adjacent to a retaining wall to be extended; A retaining wall cutting step of forming a cut-out portion with respect to a rear end of the retaining wall; A horizontal drilling process for forming a transverse fixing hole between existing reinforcing bars exposed by the cut-out portion; A reinforcing steel reinforcing step of forming a reinforcing steel to be engaged with the existing reinforcing steel while being inserted into the fixing hole; A reinforcement step of reinforcing the reinforcing bar and the reinforced concrete part to form a concrete reinforcing part at the rear end of the retaining wall including the cut part; A vertical drilling step of forming vertical fastening holes on the upper surface of the existing retaining wall and the upper surface of the reinforcing part; Anchor fixing step of fixing a fastening anchor to the fastening hole; A beam clamping step of fixing a support beam protruding in both directions from above the retaining wall using the fastening anchor; And an indispensable assembly process for sequentially joining a cross bar, a floor material and a railing to the upper part of the support beam.

The present invention can provide excellent structural stability compared to a cantilever beam of a conventional cantilever type due to the support beam structure of both the arms, thereby greatly reducing the maintenance and repair cost for the extended guide, Since both sides can be used, it is possible to maximize the available floor area of the expanded cargo, so that the pedestrian can be freely interchanged or traveled. In addition, the reinforced installation using the existing retaining wall allows the support beam to be firmly and stably engaged and fixed, The amount of steel material used for constructing the steel pipe, and the additional reinforcement and the supplementary work can be simplified, which is very reasonable because it is possible to shorten the construction period while having excellent economic effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which FIG. 1 to FIG.

1, the retaining wall 100 has a shape of a slope 200, and the other side of the retaining wall 100 is formed as a river or a road, as shown in FIG. The construction method of the present invention can be applied to a place where a river or a road is not formed, or a place where the road or the like is not made, or the road is made very narrowly.

In the present invention, as shown in FIG. 2, the retaining wall 100 to which the extended guide is to be installed is subjected to a trench construction to remove the upper soil of the inclined sheet 200 contacting the retaining wall 100, The working groove 201 corresponds to a space portion for reinforcing the rear end of the retaining wall 100. [

When the working groove 201 for the slope 200 is formed as described above, the process of cutting the retaining wall with respect to the rear end of the retaining wall 100 may be performed. In the process of cutting the retaining wall, Is formed by removing a part of the back surface of the retaining wall 100 according to the installation position of the support beam necessary for installation of the extended guide.

The cutting process of the retaining wall 101 is performed at regular intervals along the retaining wall 100 so that the cutout portions 101 and 101 'are formed on the retaining wall 100. The cut portions 101 and 101' ', The existing reinforcing bars 102 disposed inside the retaining wall 100 remain exposed.

In this state, as shown in FIG. 3, a horizontal drilling process for drilling a plurality of fixing holes 103 in the transverse direction with respect to the cutouts 101 (101 ') may be performed. Is formed for the purpose of supporting a reinforcing portion newly formed by using the cutouts 101 and 101 '. When the fixing hole 103 is made, a reinforcing bar 104 (see FIG. 4) Is inserted and fixed in the fixing hole 103 and the reinforcing steel reinforcing process for firmly connecting the existing reinforcing bars 102 and the reinforcing reinforcing bars 104 is performed.

The reinforcement reinforcement 104 is added to secure the rigidity of the reinforcement 300 to be formed on the upper rear surface of the retaining wall 100. In the reinforcement reinforcement process, The reinforcing bars 104 are inserted into the fixing holes 103 and the reinforcing bars 104 are inserted into the fixing holes 103 by inserting an anchor or the like, Or a hardening resin) may be injected into the retaining wall 100 so that the reinforcing bar 104 can be firmly fixed to the retaining wall 100.

When the binding operation is performed on the reinforcing bar 104, the reinforcing bar 104 is reinforced by concrete so that the reinforcing bars 104 are embedded in the reinforcing bars 104, including the cutouts 101 and 101 ' The upper surface of the reinforcing part 300 is formed to be equal to or similar to the upper surface of the retaining wall 100 so that the reinforcing part 300 can be fastened to the reinforcing part 300. [ So that the beam 400 can be placed and fixed with a large area.

6, when the reinforcing part 300 is fully cured and cured, the molds are removed. Then, as shown in FIG. 6, the upper surface of the existing retaining wall 100 and the insertion holes 105 ', As shown in FIG. 7, when the insertion holes 105 and 105' are completed, a separate hole 105 'or 105' is formed in each of the insertion holes 105 and 105 ' The anchor fixing process for inserting and fixing the anchors 106 and 106 'is performed.

At this time, the fastening anchors 106 and 106 'are inserted into the insertion holes 105 and 105' while injecting the hardened mortar into the inside of the fastening anchor 106 'and 106' Can be firmly fixed to the insertion holes 105 and 105 ', thereby forming a strong sense of solidarity with the retaining wall 100 and the reinforcing part 300.

As shown in FIG. 8, the buffer pad 500 may further be formed in close contact with the upper surface of the retaining wall 100 in the present invention. The cushioning pad 500 may be formed in a manner such that the upper surface of the retaining wall 100 and the reinforcing portion 300 are exposed to the outside through the fastening anchors 106 and 106 ' And the buffer pad 500 may be securely adhered and fixed using an adhesive if necessary.

9, when the fixing pads 500 and the fastening anchors 106 and 106 'are fixed to each other, the support beam 400, which is separately provided on the upper portion of the retaining wall 100, A beam clamping process may be performed to securely fasten the retaining wall 100 and the reinforcing portion 300 and the support beam 400 to each other by bolts, nuts, or the like.

The support beams 400 are continuously extended from the upper portion of the retaining wall 100 at predetermined intervals according to the intervals between the cutouts 101 and 101 'and the corresponding reinforcement portions 300 formed at a predetermined interval in the process of cutting the retaining wall. The support beam 400 is fixedly formed in the form of two arms from above the retaining wall 100.

10, a fastening support part 403 is formed so that the support beam 400 is deflected to the lower side of the upper plate 400 at one side, and a fastening anchor (not shown) is fastened to the bottom surface of the fastening support part 403. [ The reinforcing bars 404 and 404 'welded to both sides of the fastening support portion 403 so as to be orthogonal to the upper plate 401 are vertically penetrated through the fastening holes 402' Is formed.

The supporting beam 400 is supported on the upper side of the retaining wall 100 so that one side of the supporting beam 400 is protruded toward the sloping sheet 200 which is one side of the retaining wall 100 And one side of the support beam 400 protrudes from the other side.

Accordingly, since the cantilever beams are not cantilever-shaped but cantilevered beams that protrude only to one side of the retaining wall 100 as in the conventional construction method, the available space on the retaining wall 100 is maximized, Since the moments due to the two arms are applied to the retaining walls between the retaining walls as well as the moment due to the conventional cantilevers, the load or stress acting on the retaining wall 100 is remarkably reduced, which is very advantageous in maintaining the durability of the retaining walls or the retaining walls.

When the beam clamping process is finished, a cross bar 410 connecting adjacent supporting beams 400 to the upper portion of the support beam 400 is fastened to the support beam 400 at regular intervals as shown in FIG. 12 and fixing the railing 430 to both ends of the supporting and supporting beam 400 of the floor material 420 such as a deck plate or a wooden scaffold on the cross bar 410 as shown in FIG. The construction of the extended guide according to the present invention can be terminated.

As a result, the load applied to the fastening portion between the retaining wall and the support beam and the stress are reduced as compared with the conventional method, The support beams 400 fastened to the retaining wall 100 from the upper side in the form of both arms can be constructed in a wider area than in the prior art, And it is a very significant point in terms of space creation because the extension guide is formed to a part of the lower part of the slope and the efficiency and construction rationality can be greatly improved by securing the structural stability and the wide usable area.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as defined by the appended claims.
