Abstract

(57) [Summary] (Modifications required) [Problem] The present invention relates to a retaining wall structure using a conventional block, and especially in the case of construction on a river or lake shore. Provided is a sling block having a function of being able to escape or grab from anywhere when it falls. SOLUTION: The shape of a block front portion (surface exposed portion) is such that a concave portion 1 (step function hole) or a convex portion 4 is kept substantially horizontal after construction of a block retaining wall.
(Step function part) or by building a retaining wall with a knowledge block composed of both, if you fall accidentally,
By adopting a structure that can escape relatively easily from any block surface, this reduces man-made disasters and also has a vegetation function.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention can be applied to block retaining walls such as river revetments, lake revetments and road retaining walls. It is related to the improvement of the knowledge block.

[0002]

[Prior art]

  Conventionally, for the majority of public works, as a construction work for river bank protection and road slope protection. In terms of workability and cost, a block that is commonly used as a knowledge block is used. There are many slopes, but especially when used for river bank protection, a steep slope of about 1: 0.5 is common. Therefore, if you fall, you can escape without moving to the stairs or ladder. In addition, since there is almost no place to grab, it is dangerous to be swept or drowned. There was steepness.

[0003]   Also, in recent years, due to the consideration for the environment, adopting environmental conservation type knowledge block. Although various types have been developed and various types have been developed, a special molding form is required. Or a large production device for bonding various materials to the surface of the block And changes in the process are required, and the cost is inevitably high, so we have to wait for adoption. It was often done.

[0004]

[Problems to be solved by the device]

  The problem to be solved by the present invention is the surface shape of the conventional general knowledge block. Has been slightly modified to improve the structure with clues and pedestals on the surface, It was devised for the purpose of contributing to the prevention of human accidents.

[0005]

[Means for Solving the Problems]

  Machi block product is a public product, if it is not specified in the design document, it is a valley product. It is supposed to be done (see FIGS. 13 and 15). When the work is done, the central part of the front (surface) of the Machi-miko block will be almost horizontal. Recessed portion (step function hole) 1 that functions as a grip and a foothold, or the same function With a convex portion (step function portion) 4 or a concave portion with the same function (step machine) Nouchi-buu, which is characterized by being composed of a function hole 1 and a convex portion (step function portion) 4. It's a lock.

[0006]

[Embodiment of device]

  Regarding Claim 1, as shown in FIGS. 1 to 5, the front portion (exposed surface) of the Machi block. When a valley as shown in Fig. 13 is made near the center, it is almost , A structure that functions as a step by providing recesses on the top and bottom so as to be kept parallel This is the block block for retaining walls.   As for the reason why it is provided above and below, the same effect can be obtained by rotating the product. By adopting a unique structure, we aim to reduce the types of products and improve manufacturing and workability. It is a target.

[0007]   Regarding claim 2, as shown in FIGS. 7 to 11, an obelisk having the same function as above. It has a convex shape so that you can crawl from anywhere on the slope. Therefore, it is a problem in terms of strength calculation as a retaining wall of a product that a recess as in claim 1 is provided. It was taken into consideration as a countermeasure against such a situation, and the vegetation function described below has been considerably lost. However, it is a knowledge block that can achieve the first purpose of preventing human disasters with the simplest structure. It is ku. The obelisk shape makes it easy to remove the mold during the manufacturing process. This was done in consideration of being able to do it, and it will affect the function. Not of.

[0008]   As for claim 3, as shown in FIGS. 13 to 18, both of claim 1 and claim 2 are combined. The depth of the recess (step function hole) 1 according to claim 1 is made shallower. In addition, the convex portion having the obelisk shape according to claim 2 is provided, which is a drawback of claim 1. It is a wisdom block that solves the strength problem, and can be expected to be effective as the vegetation function part 5. It is something.

[0009]

【Example】

  In the case of Tanizumi, the leaning direction of the intelligent block changes for each stage. 4, combining two types of blocks as shown in FIG. 8 and FIG. 10 or FIG. 14 and FIG. If steps are performed, steps with intervals of about 30 cm will be formed on the entire surface of the block, It can be used as a clue and a foothold for the work, and can contribute to the prevention of human accidents.

[00010]

[Effect of device]

  Due to the above shape, the convex portion (step function portion) or the concave portion (step function portion) Hole) became a clue and a foothold for escape when falling, especially when it increased water As it can crawl up, it has the effect of reducing human disasters.   Further, regarding the intelligence block of claim 1 and claim 3 as an added value, the upper part The concave part of the part functions as the vegetation function part 5, and contributes to greening with accumulated sediment. The intelligence block can be realized with the minimum improvement of the conventional product.
