Preferably, the number of the bamboo strips is several, and the bamboo strips are distributed in a crossed manner.

Preferably, the top surface of the cement is rammed to the bottom surface of the rammed soil.

Preferably, the rammed soil comprises 0.05% of wheat straw and 5% of cement, and the balance of soil.

Preferably, a pouring hopper is arranged above the rectangular template, and the top surface of the pouring hopper is sunken.

Preferably, the surface of the material pouring hopper is provided with nylon cloth or plastic cloth.

The technical scheme of the utility model has the following beneficial effects:

in the scheme, from the aspect of practical application, a construction method which is environment-friendly and economical and can effectively improve the earthquake-resistant performance of a raw soil building is needed, and the requirement can be met by doping wheat straws and cement into a wall body and arranging a bamboo fence in the bottom.

In the scheme, the bamboo wood has good heat absorption and moisture absorption performances, is a fiber material with good tensile strength, compressive strength and bending strength, can be well combined with a rammed earth wall in mechanism, and can accelerate cement hardening through heat absorption.

In the scheme, the strength of the wall body can be improved by adding cement, the ductility of the wall body can be improved by adding wheat straws, and the shear resistance of the bottom can be further improved by arranging the bamboo fence in the bottom. The combination of the three can improve the bearing capacity and the energy consumption capability of the wall body.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments, the description of which is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention in any way.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

Example one

As shown in fig. 1-4, an embodiment of the present invention provides a bamboo fence rammed earth wall with a built-in bottom, including a rubble 1, a rectangular groove 2 is formed on a top surface of the rubble 1, cement 3 is filled in the rectangular groove 2, bamboo strips 4 are arranged inside the cement 3, a rectangular template 5 is arranged on the top surface of the rubble 1, a ramming groove 6 is formed inside the rectangular template 5, ramming earth 7 is arranged inside the ramming groove 6, a top surface of the cement 3 is connected with a bottom surface of the ramming earth 7, and the ramming earth 7 covers the bamboo strips 4.

Wherein, the number of the bamboo splints 4 is a plurality, and the bamboo splints are distributed in a cross way.

Wherein the top surface of the cement 3 and the bottom surface of the rammed soil 7 are rammed with each other.

Specifically, the depth of the rectangular groove 2 can be 6-15 cm, the interval between the bamboo strips 4 is 3 cm, the height of the bamboo strips 4 is about 80 cm, and the cement 3 and the rammed soil 7 are finally rammed into a rammed soil wall with the length of 480 cm, the width of 60 cm and the height of 350 cm.
