Description
Technical field
The utility model belongs to Construction for Hydroelectric Project technical field, relates to a kind of gravity retaining wall, specifically relates to a kind of gravity retaining wall ruggedized construction.
Background technology
Gravity retaining wall, refers to the retaining wall that relies on wall body deadweight opposing soil body lateral pressure.Gravity retaining wall available block stone, slabstone, concrete precast block be as masonry, or adopt sheet stone concrete, concrete to carry out monobloc cast.Half gravity retaining wall can adopt concrete or few reinforced concrete to build.Gravity retaining wall can build up with barnacle or concrete, and as shown in Figure 1, gravity retaining wall is generally all made simple trapezium structure.Its advantage is to gather materials on the spot, easy construction, good economical benefit.So gravity retaining wall is widely used in the engineerings such as China railways, highway, water conservancy, bay, mine.
Therefore yet because gravity retaining wall is to maintain balance and stability by deadweight, and volume and weight is larger, there is the defects such as anti-seismic performance, resistance to overturning and resistance to capsizing be poor.For overcoming the existing deficiency of above-mentioned gravity retaining wall, at present, gravity retaining wall or half gravity retaining wall have mostly carried out consolidation process when construction.The Chinese patent that is CN203256771U as publication number discloses a kind of half gravity mainboard associating retaining wall structure, this invention is that corresponding back up is set on wall column, interlaced arrangement and combining as a whole between adjacent wall column and wallboard, described back up is for reinforcing the gravity stone-laying structure of wall column.Although adopt this technical scheme can save constructional materials and resource, guaranteed the safety of protective slope structure and stablized.But retaining wall self stability is poor, during the construction of wall column back up, formwork erection is more difficult, and need to adopt dedicated templates construction, and then increases construction cost, and this retaining wall structure is not suitable in the gravity retaining wall that volume and weight is larger simultaneously.
For another example, the Chinese patent that publication number is CN202380481U discloses a kind of cemented rock and Combined concrete Form Gravity Breast Wall, and this body of wall is by grouting rock layer and layer of concrete forms; Grouting rock layer and layer of concrete adopts the occlusion structure of horse tooth trough shape to be connected as a single entity; Body of wall inside is provided with the gutter of some perforation body of wall medial surfaces and lateral surface.Described body of wall be take concrete as main body, and cemented rock is done inner filling.Or described body of wall be take cemented rock as main body, tension side adopts layer of concrete.The technical program is that bi-material is combined, although simple concrete gravity type retaining wall cost is more saved, can significantly improve the gear soil bearing capacity of cemented rock barricade.But in the technical program, owing to being only interlocked by horse tooth trough shape between masonry block layer and layer of concrete, between seam without any ruggedized construction, As time goes on, easily cause body of wall to occur crack, sink, topple and sliding rupture, thereby affect the safety of building.If gravity retaining wall is removed to reconstruction, invest hugely, waste time and energy.Therefore how gravity retaining wall is reinforced, and is problem demanding prompt solution in current gravity retaining wall work progress.
Utility model content
For addressing the above problem, the utility model provides a kind of gravity retaining wall ruggedized construction.
The utility model is achieved by following technical solution.
A kind of gravity retaining wall ruggedized construction, comprise retaining wall, described retaining wall outside has additional reinforced concrete barricade, and described retaining wall adopts some anchor poles to be connected with the bonding surface of reinforced concrete barricade, and anchor pole is positioned at upwards bending structure of reinforced concrete barricade one end one-tenth.
Described retaining wall is monobloc cast concrete or stone masonry gravity retaining wall.
Described reinforced concrete barricade is monobloc cast concrete retaining wall.
Described anchor pole adopts the reinforcement fabrication of HRB400, and bar diameter is 25mm.
Described anchor pole is evenly distributed on retaining wall.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is by the connection of anchor pole, make original unstable gravity retaining wall and young concrete form integral body, the overturning or slip resistance analysis that has improved former gravity retaining wall, antiskid moves ability, has avoided former gravity retaining wall to remove, the shortcoming of reconstruction and overlapping investment, the utility model has only increased less engineering quantity and investment, just can play the reinforcement effect to former gravity retaining wall, has significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is traditional gravity retaining wall structural representation.
In figure: 1-retaining wall, 2-reinforced concrete barricade, 3-anchor pole.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of gravity retaining wall ruggedized construction described in the utility model, comprise retaining wall 1, described retaining wall 1 outside has additional reinforced concrete barricade 2, described retaining wall 1 adopts some anchor poles 3 to be connected with the bonding surface of reinforced concrete barricade 2, and anchor pole 3 is positioned at upwards bending structure of reinforced concrete barricade 2 one end one-tenth.Adopt the technical program, by the connection of anchor pole, make original unstable gravity retaining wall and young concrete form integral body, the overturning or slip resistance analysis that can greatly improve former gravity retaining wall 1, antiskid moves ability, has avoided retaining wall 1 to remove, rebuild the shortcoming of overlapping investment.The technical program is when construction, first the foundation excavation of needs is completed, again by the surperficial dabbing of retaining wall 1, then at retaining wall 1 external surface, arrange anchor pole 3, anchor pole 3 parts are imbedded in retaining wall 1, and a part exposes, and finally in retaining wall 1 outside, build certain thickness concrete, form reinforced concrete barricade 2, reinforced concrete barricade 2 forms new gravity retaining wall with retaining wall 1 combination.
Described retaining wall 1 is monobloc cast concrete or stone masonry gravity retaining wall.Construction is simple, can gather materials on the spot, and small investment.
Described reinforced concrete barricade 2 is monobloc cast concrete retaining wall.
Described anchor pole 3 adopts the reinforcement fabrication of HRB400, and bar diameter is 25mm.
Described anchor pole 3 is evenly distributed on retaining wall 1.Make it stressed evenly, further increase the stability of gravity retaining wall.
Below in conjunction with accompanying drawing, further illustrate implementation step of the present utility model:
As shown in Figure 1, the utility model is when implementing, and main operational steps step is as follows:
The first step, the thickness of the newly placed concrete (being reinforced concrete barricade 2 in Fig. 1) increasing as required, excavates out the basis needing;
Second step, by the surperficial dabbing of former gravity retaining wall (being retaining wall 1 in Fig. 1);
