Abstract
The utility model discloses a clamping reed for geogrids, which comprises a clamping base and a clamping block connected with each other. Four raised lug bosses are formed on the upper end surface of the clamping base, a crossed space is formed in the middle of the four lug bosses, clamping holes are formed on the lug bosses, and clamping hooks which can be in tight fit with the clamping holes on the clamping base are arranged on the edges of the clamping block. Two geogrids can be connected by placing the corresponding nodes formed on the edges of the two geogrids into the cross space and then clamping the clamping base with the clamping block. A geogrid composed of two geogrids connected through the utility model is reliable and stable in structure, and can effectively ensure force transfer between the two geogrids.
Description
Technical field
The utility model relates to a kind of geo-grid with blocking reed.
Background technology
Geo-grid has its special status in each series of geotechnological material, in engineerings such as reinforced earth bulkhead, treatment of soft foundation, all kinds of dam foundation roadbed, side slope protection, flexible pavement, the irreplaceable advantage of many other geotechnological materials is arranged, and development prospect is very considerable.Geo-grid has the hot strength height (greater than 200kN/m, elongation per unit length is less than 1.5%), good, corrosion-resistant, the anti-aging (design service life 120 years of dimensional stability, underground), the wide characteristics such as (50 ℃～120 ℃) of serviceability temperature, being widely used in the structure of the protection of slope, danger, soft foundation processing, reinforced earth bulkhead engineering and some high-bearing capacities, is the new material that is with historically new significance in the building trade.For example, geo-grid is used for the railway bed reinforcement protection, and grid and ground surface material merge, and can distribute load effectively, prevents that ballast aggregate runs off and subgrade deformation, improves the stability of roadbed, bears bigger change lotus.Geo-grid developing rapidly at home had benefited from national large-scale basis construction, and more and more stricter road quality requires and environmental protection.The application of geo-grid has significantly reduced the amount of occupying cultivated land and earthwork evacuation amount, and the amount of stone that needs when handling weak soil.Along with the raising of domestic cost of labor and strict more environmental requirement, the economic benefit of geo-grid can be more obvious.
Steel is moulded geo-grid, the plastics geo-grid is present most widely used grid product, wherein steel mould geo-grid with high tensile steel wire (or other fibers) through specially treated, with polyethylene (PE) and add other auxiliary agents, make it to become compound high-strength tension band by extruding, and there is coarse embossing (friction factor can greater than 0.5) on the surface, single thus band is arranged through longitudinal and transverse establishment at a certain distance or clamping, adopts the bonding welding technology of special strengthening to weld its interface point and moulding.After longitudinal and transverse establishment at a certain distance, grid node at high temperature welds, bonds or is formed by injection molding type the plastics geo-grid in length and breadth with plastic strip.Adopt these coupling methods make geo-grid in length and breadth the mechanical property of interface point have significantly and to reduce, be even cause the interface point not prison welding that these all have a strong impact on workmanship again.
In sum, how to make the connection of geo-grid both guarantee the transmission that grid is stressed, guarantee again not cause the problem that mechanical property is declined to become needs solution because of point of attachment.
The utility model content
The purpose of this utility model is to provide a kind of geo-grid with blocking reed.
The technical scheme that realizes the utility model purpose is: a kind of geo-grid is with blocking reed, the deck and the fixture block that comprise mutual clamping, the upper surface of deck is provided with four boss that raise up, form a cross space in the middle of four boss, boss is provided with button hole, and the edge of fixture block is provided with and the close-fitting grab of the button hole of deck.
The draw-in groove that the bottom laterally or longitudinally in the cross space on the described deck is set to sink; The lower surface of described fixture block be provided with two to lower convexity projection, projection is positioned at the top at draw-in groove two ends, height protruding under the projection is identical with the height of boss epirelief.
Described deck and fixture block are square, and boss and grab are arranged at respectively on four angles of deck and fixture block.
Described deck and fixture block are all by the molding disposal molding.
The utlity model has following beneficial effect: form a cross space in the middle of (1) four boss of the present utility model, the respective nodes at the edge of two geo-grid is placed in this cross space, then with deck and fixture block clamping, just can realize two connections between the geo-grid, by the geo-grid after the utility model connection, Stability Analysis of Structures is reliable, can effectively guarantee the transmission that grid is stressed.
(2) bottom laterally or longitudinally in the cross space on the deck of the present utility model draw-in groove that is set to sink, this structure makes the utility model can stably connect the vertical, horizontal rib not in conplane geo-grid, improves workmanship.
(3) deck of the present utility model and fixture block are square, and boss and grab are arranged at respectively on four angles of deck upper surface and fixture block lower surface, and this structure makes the utility model simple in structure, and has saved cost, are convenient to produce.
(4) deck of the present utility model and fixture block are all by the molding disposal molding, and this structure makes the utility model to produce in batches easily, and cost is low, Stability Analysis of Structures.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model deck.
Fig. 3 is the structural representation of the utility model fixture block.
Label is in the accompanying drawing:
The specific embodiment
(embodiment 1)
Present embodiment comprises the deck 1 and the fixture block 2 of mutual clamping.
When geo-grid need connect lengthening, the respective nodes at the edge of two geo-grid is placed in the cross space 12 of deck 1, the vertical, horizontal rib of geo-grid is positioned over respectively in the upper surface and draw-in groove 14 of deck 1, with deck 1 and fixture block 2 clampings, just can stablize the connection that realizes between two geo-grid then.
(embodiment 2)
Present embodiment is substantially the same manner as Example 1, and difference is the draw-in groove 14 that the bottom longitudinally in the cross space 12 on the deck 1 is set to sink.
Should be appreciated that specific embodiment described above only is used to explain the utility model, and be not used in qualification the utility model.Conspicuous variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
