Description

Environment load-reducing type light embankment stone

Technical Field

The utility model relates to an environment off-loading type lightweight embankment stone belongs to embankment construction technical field.

Background

The traditional embankment is a relatively gentle side slope arranged on two sides of a roadbed, is a line building which is filled with soil or stones and has certain compactness, and is formed by filling (filling earthwork or stone layer by layer) or rolling (rolling the embankment with soil and stone layer by layer in a segmented mode, so that the traditional embankment is not only complex in construction process and long in construction time, but also occupies relatively large land area due to the fact that the embankment which is obliquely arranged occupies relatively large land area, and unnecessary land resource waste is caused. In addition, the stability of the traditional embankment is poor, and the embankment is easy to collapse after being corroded and washed by rainwater.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: provided is an environment-relief lightweight embankment stone which can quickly construct an embankment and can reduce the land area occupied by the embankment.

In order to solve the technical problem, the utility model provides a technical scheme is: the utility model provides an environment off-loading type lightweight embankment stone, includes prefabricated base member, the top surface of base member is equipped with the proruption shear force key that makes progress, the bottom surface of base member is equipped with the cell body that matches with shear force key shape, position homogeneous phase, the left and right side of base member all is equipped with the water drainage tank that extends forward from the back.

Preferably, the matrix is made of UHPC or geopolymer.

The utility model discloses when using, form the embankment through piling up the embankment stone, it is convenient fast to be under construction, prevents the embankment stone and vertically slides in the cooperation that transversely passes through shear force key and cell body, makes the tight block of adjacent embankment stone be in the same place under the extrusion force effect of vertical through soil simultaneously, finally forms the embankment. Compared with the traditional embankment, the utility model discloses can reduce the slope of embankment, can make the vertical setting of embankment even, just so can reduce the land area that the embankment occupy, utilize land resource effectively. In addition, the utility model discloses a UHPC or geopolymer make, and the ability of anti rainwater corrosion and erosion improves greatly than traditional embankment, therefore stability also improves greatly than prior art.

In order to facilitate the installation operation, the technical scheme is further improved as follows: and the base body is provided with a lifting hole for lifting. Therefore, the crane can be used for direct hoisting operation.

The technical scheme is further improved as follows: the matrix is provided with lightening holes penetrating through the matrix from top to bottom and a mesh belt penetrating through the lightening holes, the lightening holes are located in the middle of the matrix, and two ends of the mesh belt are anchored into soil when the mesh belt is used. Preferably, the mesh belt is a geogrid steel mesh or a carbon fiber fabric mesh. The civil engineering grid reinforcing mesh and the carbon fiber mesh have the advantages that the composite material is long in durability, corrosion-resistant, resistant to chemical erosion and good in mechanical property, so that when the civil engineering grid reinforcing mesh and the carbon fiber mesh are used, the mesh belt is horizontally anchored into soil behind a matrix to serve as a reinforced retaining wall, and the strength and the stability of the embankment are further improved.

Preferably, the front side surface of the base body is provided with decorative grains. The embankment installed in this way is more beautiful and elegant.

Drawings

The present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a first embodiment of the present invention.

Fig. 2 is a schematic structural diagram of a second embodiment of the present invention.

Reference numerals: the shear connector comprises a base body 1, shear connectors 2, a groove body 3, a drainage groove 4, hanging holes 5, decorative patterns 6, lightening holes 7 and a mesh belt 8.

Detailed Description

Example one

The environment off-loading lightweight embankment stone of this embodiment, as shown in fig. 1, including prefabricated base member 1, the top surface of base member 1 is equipped with the protruding shear force key 2 that makes progress, the bottom surface of base member 1 is equipped with the cell body 3 that matches with shear force key 2 shape, position homogeneous phase, the left and right lateral surface of base member 1 all is equipped with the water drainage tank 4 that extends forward from the back, and water drainage tank 4 can make the infiltration in the soil discharge fast, prevents that the embankment from collapsing.

Preferably, said matrix 1 is made of UHPC or geopolymer. UHPC (Ultra-High Performance concrete) is short for Ultra-High performance concrete, has Ultra-High durability and Ultra-High mechanical property, is the most innovative cement-based engineering material in the last thirty years, and realizes the large span of the performance of the engineering material. The geopolymer is a polymer made of AlO₄And SiO₄The inorganic polymer with three-dimensional net structure formed by tetrahedral structure units has excellent mechanical property, acid and alkali resistance, fire resistance and high temperature resistance.

In this embodiment, the shear key 2 is a hemisphere, and the groove body 3 is a semicircular groove. Of course, the shear key 2 may have other forms, such as a strip shape or a track-like shape, and so on. The number of the shear key 2 can be one or more, and the specific number can be set according to the needs.

In addition, the embankment stone has heavy dead weight, and a hoisting hole 5 for hoisting is arranged on the base body so as to facilitate the direct hoisting operation of a crane. As shown in fig. 1, a through hole or a counter bore is formed in the middle of a base 1, a hanging rib is mounted on the wall of the through hole or the counter bore, and the hanging rib and the wall of the bore are combined to form a hanging hole for hanging operation. Of course, the hanging hole can be in various forms, such as the hanging hole is directly preset on the shear key 2 or the top surface of the base body 1.

Preferably, the front side surface of the base body 1 is provided with decorative veins, so that the installed embankment is more beautiful and elegant.

Example two

The embodiment is an improvement on the first embodiment, and the improvement is as follows: as shown in figure 2, the matrix 1 is provided with lightening holes 7 penetrating through the matrix from top to bottom and a mesh belt 8 penetrating through the lightening holes 7, the lightening holes 7 are positioned in the middle of the matrix 1, and two ends of the mesh belt 8 are anchored into soil when in use. Preferably, the mesh belt 8 is a geogrid steel bar mesh or a carbon fiber fabric mesh. When the reinforced retaining wall is used, the mesh belt 8 is horizontally anchored into soil behind the base body 1 to serve as a reinforced retaining wall, and therefore the strength and the stability of the embankment are further improved.

The embankment stone of this embodiment can directly fill in rubble or soil etc. in the lightening hole after the installation, can help handling building construction rubbish firstly, and secondly the downthehole filler of lightening of adjacent embankment stone can form the column and support, improves the stability and the intensity of embankment.

The present invention is not limited to the specific technical solutions described in the above embodiments, and other embodiments can be provided in addition to the above embodiments.
