JPH05321265A - Method for constructing slope face with precast concrete block - Google Patents

Abstract

PURPOSE:To shorten operations with a construction method which uses concrete blocks for stabilizing a slope face by making very perfect the relation between a reinforcing netting and the ground, and also making safe and certain the relation to blocks. CONSTITUTION:A detention part 4 to be coupled with reinforcing netting is formed on the back upper surface of a reinforcing retaining wall part 2 of a concrete block 1, and such blocks are laid in line one stage over another, followed by back fill, laying of a reinforcing netting, forming a detention part 7 at its foremost extremity, and detaining with the detention part of concrete block. Further the tail of the netting is folded to form a weight accommodation part 5 in cylindrical form, which is filled with weights 6, and they are laid in line on the first stage blocks where concrete blocks are laid in line, followed by back fill. Reinforcing netting is detained with the detention part of the block and laid, and its tail is filled with weights. This cycle of operations is repeated, and the intended slope face is constructed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a slope with a precast concorre block.

[0002]

2. Description of the Related Art Various kinds of precast concorrelate blocks have been developed. In particular, regarding the large precast concord block, which was developed by the applicant of the present application and had an industrial property right, when performing work by combining this type of block and a reinforcing net, The relationship with the blocks and the ground was somewhat unsatisfactory. For example, after the reinforcement net was installed, it was fixed to the ground with a kind of pile, and it was stopped at a point when a little big force was applied, so the reinforcement net might break. The relation with the block was also incomplete.

[0003]

SUMMARY OF THE INVENTION According to the present invention, the relationship between the reinforcing net and the ground is extremely complete, and the relationship with the block is a safe and reliable structure, and the work process of the construction method is shortened. The purpose is to provide a possible construction method.

[0004]

According to the present invention, there is provided a large precast concorte block having an engaging portion for engaging a reinforcing net on the rear upper surface of a reinforcing ridge wall portion, and an engaging portion of the block at the front end portion. First, the large-scale precast concorre block is embedded side by side on the slope surface of the ground to be stabilized, one by one, by means of the reinforcing mesh having the cylindrical weight accommodating portion formed in the rear portion. It is returned, the engaging portion of the reinforcing mesh is engaged with the engaging portion of the block, and the weight is laid in the weight storing portion at the rear end of the reinforcing mesh located in the stable portion of the ground. Then, the precast concorte blocks are placed side by side on the first-stage blocks arranged side by side to backfill them, and the engaging portion of the front end portion of the reinforcing net is engaged with the engaging portion of the block. Laying a reinforcing net and storing the weight of the rear end of the reinforcing net Min filled with weight, it constitutes a conducted slopes repeated sequentially such work.

[0005]

Since the present invention is the construction method as described above, the relationship between the reinforcing net and the ground is completely assured, and the relationship with the large precast concorre block is also a safe and reliable structure, and is safe. The construction period is shortened. In addition, the blocks can be made as much as the conventional blocks, and the reinforcing net only needs to form the engaging part at its end, which is extremely safe compared to the conventional method of this type. In addition, the construction period can be shortened.
In this case, the effect is further improved by forming a drainage structure in the reinforcing net.

EXAMPLES Next, examples of the present invention will be described. Large precast concorre block 1 that composes the slope
Is formed on the rear upper surface of the reinforcing retaining wall portion 2 of the above, and the large precast concorreate blocks 1 are juxtaposed one by one for backfilling, and the reinforcing net 3 is attached. The block 1 is installed at the front end of the reinforcing net 3.
After forming an engaging portion 7 that engages with the engaging portion 4 of the block 1, the engaging portion 7 is engaged with the engaging portion 4 of the block 1, and is further positioned at the stable portion A of the ground of the reinforcing net 3. The end portion is bent to form a cylindrical weight storage portion 5, and the weight storage portion 5 has a weight 6 ...
And then the precast concorte blocks 1 are juxtaposed on the juxtaposed first-stage blocks 1 to perform backfilling, and the engaging portion 7 at the front end of the reinforcing net 3 is engaged with the block 1. The reinforcing net 3 is laid by engaging the joint portion 4, and the weight storage portion 5 at the rear end portion of the reinforcing net 3 is filled with the weight 6, and such a work is sequentially repeated to obtain a desired weight. It constitutes the slope. In this case, contrary to the case where the weight storage portion 5 is formed so as to be embedded from the backfilled soil surface,
The case where it is formed so as to project above the surface and the case where both are formed are considered.

The present invention is carried out by stacking the large precast concorte blocks 1 in several stages by the above-mentioned construction method, but of course, it may be sufficient to simply arrange the large precast concorre blocks 1 in a row. . Further, the effect is further improved by forming the reinforcing net 3 in a water-removing configuration. For example, by constructing the reinforcing net 3 having a material or shape that causes a capillary phenomenon, the effect can be improved. can get. Further, various forms of the engaging portion 4 of the block 1 and the engaging portion 7 of the front end portion of the reinforcing net 3 are conceivable, and are conventionally used for engaging with the upper block formed in this type of block. The recess can be used as it is.

The weight 6 may have any shape,
Although pebbles and aggregates are easy to use, it is more preferable to use a concrete block having a shape that matches the weight storage portion 5, which contributes to labor saving in construction.

The shape of the large-sized precast concorre block 1 can be sufficiently utilized in the conventional shape, and the hook wall 2 has a connecting hole used for connecting with the adjacent block 1 and a large size for the bottom slab. A through hole is provided or a water drain hole is formed below the front wall.

[0010]

EFFECTS OF THE INVENTION Since the present invention has the construction method as described above, the relationship between the reinforcing net and the ground is completely ensured, and the relationship with the large precast concorre block is also a safe and reliable structure, and is safe. Therefore, the construction period is shortened.

Further, the block can be manufactured as much as the conventional block, and the reinforcing net only needs to form the engaging portion at its end, which is more than the conventional method of this type. It is extremely safe and the construction period can be shortened.
