Abstract

PURPOSE:To make easier the construction work of slope frame structures as well as raise their strength for protecting the slope of the ground by a method in which a specific shape of slope frames having holes through which cement mortar is to be poured are fixed to the slope and then cement mortar or the like is placed into the hollow parts of the slope frames. CONSTITUTION:Slope frames 1 having cement mortar-pouring holes 2 drilled at a given interval in the longitudinal direction as well as anchor inserting holes 3 in place on their upside faces, with a tubular or U-shaped cross section, are fixed to the slope by means of anchors 5. Then, cement mortar or the like is orderly poured into the hollow part A of the slope frames 1 through the holes 2 and the upper end of the slope frames 1. By this, the construction period can be shortened due to the simplified assembly of the formwork and cement mortar 6 can be poured through the holes 2, making the placement of cement mortar into the slope frames 1 exacter and easier.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a book about a method of constructing a slope structure that protects slopes.

As one of the slope protection methods, it is known to install a frame-like structure, ie, a slope frame, on the slope. This construction method often involves constructing reinforced concrete frames on slopes, but the drawback is that the assembly of the forms is difficult and requires a lot of labor and time. Additionally, a construction method has been implemented in which a steel plate is used in the formwork and the steel plate is embedded by spraying mortar, but this method has the drawback of insufficient rigidity and strength.

This invention is an attempt to eliminate the drawbacks of the conventional method of constructing a horizontal frame as described above, and is to form a tube-shaped frame or a cross-sectional mouth shape, and to apply mortar to the upper surface of the seven-frame frame at required intervals in the longitudinal direction. Open an inlet hole, install these 7 lanes on the slope and fix them to the slope with anchors, then install the mortar inlet and the upper end of the slope frame into the 9th part of the 7 lanes. The method is characterized by pouring mortar into the structure, thereby creating a slope structure that is easy to construct and has great strength, thereby stabilizing and protecting the slope.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows a metal legal framework frame 1 used as the skeleton of the legal framework in this invention.This legal framework frame 1 is formed into a tubular shape with a rectangular cross section, and its upper surface is covered with concrete or mortar cape. Inflow ports 2 through which so-called mortar flows in are provided at required intervals in the longitudinal direction of the slope frame 1, and at appropriate positions there are inlets 2 for fixing the slope frame 1 to the slope. A through hole 3 is provided through which the anchor is pushed.

Furthermore, the slope frame 1 is not limited to a tubular frame as shown in FIG. 1, but may also be a cross-sectional type with an open bottom that touches the slope, as shown in FIG. 2, for example. can.

In this invention, the above-mentioned legal framework frame IK is installed on a slope as a framework for the structure, but if the slope is extremely uneven, the ground is leveled in advance. The legal frame frame 1 is tubular (
In the case of Fig. 1), mortar can be placed on top of the slope after it has been constructed. If the legal frame frame 1 is required to have even greater strength, reinforcing reinforcing bars 4 are arranged within the legal frame 7 rays ^1. The reinforcing reinforcing bars 4 can be easily arranged by assembling several longitudinal main bars in advance so that they can be inserted into the legal framework frame 1, and inserting them from the opening at the upper end of the legal framework frame 1. Then, the anchor 5 is inserted into the through hole 3 of the slope frame 1 and driven into the ground to be identified with the slope surface.

After fixing the frame 7 frame 1, as shown in Fig. 3, mortar 6 is poured from the lowest inflow hole 2 in the direction of arrow A, and then from the upper inflow hole 2 in the direction of arrow A. 4, and then from the inlet hole 2 above it, pour it sequentially as shown by arrow C, and finally, from the opening at the upper end of frame 7 frame 1, as shown by arrow 2, The frame 1 is filled with mortar.

And, on the outer surface of the legal frame 7 frame 1 configured as described above, there is a must! ! Corresponding to this, mortar 7 is sprayed (FIG. 8) to protect the frame 1 from rust. Furthermore, this mortar 7
When spraying, wire mesh 8 is placed on the outer surface of the legal frame 1.
The adhesion of one mortar 7 will be good if it is kept uniform.

In this invention, the above-mentioned structure does not have to be applied to all structures formed in a lattice shape as a legal frame. For example, as shown in Fig. 8, only the slope of the slope in one direction of the slope is constructed using the structure according to the present invention, and the slope of the slope in the direction that intersects with the slope is constructed using the conventional structure. It can also be constructed by assembling the frame 9, arranging reinforcing bars 10, and pouring mortar. However, even in a slope that is long in the direction that crosses the slope line of the slope, it is possible to pour 6 full concrete into the slope frame 1 by opening the inlet hole 2, so that all of the slopes can be filled with concrete. Needless to say, even more effects can be achieved by applying the construction according to the present invention.

As explained above, the present invention provides inflow holes for mortar at required intervals in the longitudinal direction on the upper surface of the slope frame formed into a tubular or cross-sectional shape, and the slope frame is attached to the slope. It was installed and fixed to the slope with anchors, and then mortar was poured into the hollow part of the 7-frame slope from the mortar inlet and from the upper end of the 7-frame slope, so it was easy to assemble the formwork. This saves labor and significantly shortens the construction period, and since the mortar is poured into the slope frame, it is more efficient than the mortar spraying method. Since it is possible to pour inflow (through the inflow holes opened at various places on the soil surface of the similar method frame), it is possible to ensure that the inside of the method frame is fully filled.
It is easy to use, and can be applied to construction on gently sloped slopes and slope construction across slopes, and is excellent in slope stability and film preservation. It is capable of producing many excellent effects.
