Abstract

The utility model discloses an existing embankment heightening structure for a limited using land area, and aims at effectively avoiding occupation of important existing buildings, a river channel and the like on the side of an existing embankment. The existing embankment heightening structure for the limited using land area comprises the existing embankment (10) and an existing roadbed (11), wherein L-shaped reinforced concrete retaining walls (20) which are symmetrical about the central line of the existing embankment (10) are arranged on the existing embankment (10) after the existing roadbed (11) is dug up, and a broken stone hardcore (22) is paved between the bottom face of each L-shaped reinforced concrete retaining wall (20) and the top face of the existing embankment (10).

Description

The existing embankment of land used restricted area increases structure
Technical field
The utility model relates to the Road embankment structure, and particularly the existing embankment of a kind of land used restricted area increases structure.
Background technology
The reconstruction of existing road often will be raised to existing road surface increases rear road surface, usually carries out the embankment embankment by the side slope line after increasing.But at the land used restricted area, be subjected to the restriction of embankment both sides existing buildings or geographical conditions, if carry out the embankment embankment by the side slope line after increasing then can occupy existing building, river course, therefore need a kind of new existing embankment increase structure.
The utility model content
Technical problem to be solved in the utility model provides the existing embankment of a kind of land used restricted area and increases structure, effectively to avoid occupying existing building that existing embankment stresses to want and river course etc.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
The existing embankment of land used restricted area of the present utility model increases structure, comprise existing embankment and existing roadbed, it is characterized in that: on existing embankment, be symmetrical arranged the L-type reinforced concrete retaining wall with respect to its center line after described existing roadbed is excavated, lay hardcore bed between the bottom surface of L-type reinforced concrete retaining wall and the existing embankment end face.
The beneficial effects of the utility model are, utilize L-type reinforced concrete retaining wall 20 closing slopes, can effectively avoid occupying existing building that existing embankment 10 stresses to want and river course etc., and simple in structure, applicability is strong.
Description of drawings
This manual comprises such as next width of cloth accompanying drawing:
Fig. 1 is the cross-section structure that the existing embankment of the utility model land used restricted area increases structure.
Member shown in the figure, toponym and corresponding mark: existing embankment 10, existing roadbed 11, L-type reinforced concrete retaining wall 20, hardcore bed 22, mortar flag stone protection body 22, reinforcing pile 30.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, the existing embankment of land used restricted area of the present utility model increases structure, comprises existing embankment 10 and existing roadbed 11.On existing embankment 10, be symmetrical arranged L-type reinforced concrete retaining wall 20 with respect to its center line after described existing roadbed 11 is excavated, lay hardcore bed 22 between the bottom surface of L-type reinforced concrete retaining wall 20 and existing embankment 10 end faces.Adopt L-type reinforced concrete retaining wall 20 closing slopes, effectively avoid occupying existing building that existing embankment 10 stresses to want and river course etc.
With reference to Fig. 1, described hardcore bed 22 following intervals arrange reinforcing pile 30.If be the soft shape silty clay of moulding under embankment 10 substrates, its bearing capacity and intensity are all lower, after roadbed increases, must take reinforcing pile 30 to come consolidation process to guarantee its stability and requirement for bearing capacity, reinforcing pile 30 is controlled the effect of sedimentation in addition simultaneously, guarantees that roadbed is smooth-going.Can adopt CFG, cement mixing pile or rotary churning pile according to the described reinforcing pile 30 of base matter condition differently.
With reference to Fig. 1, the bottom outside of L-type reinforced concrete retaining wall 20 is built mortar flag stone protection body 22 by laying bricks or stones, hardcore bed 22 by upper macadam, geo-grid, lower macadam is compound consists of.
The above existing embankment of the utility model land used restricted area that just explains through diagrams increases some principles of structure, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
