Description
Technical field
The invention belongs to building materials technical field, more particularly to a kind of L-type concrete guard wall.
Background technology
Concrete guard wall is widely used retaining structure in water conservancy civil engineering, and concrete guard wall is that a kind of place is banketed
Or the structure of soil deformation unstability, it is frequently utilized in the engineerings such as slope treatment, the improvement of slag field.In engineering construction, due to place
The needs of smooth and absolute altitude control, often use Reinforced Concrete Retaining Walls.The wall of traditional concrete guard wall structure is
One piece of one-piece casting wall, the barricade generally poured using plank sheathing formwork, making the method for concrete guard wall is：First existing
Foundation trench is excavated, then lay bed course, formwork reinforcement placing on the spot after bed course is completed, finally with concreting wall.Due to
The wall of concrete guard wall structure is that a monoblock pours wall, when making wall, to wait until that reinforcing bar can just be opened after setting up
Beginning pours, and whole construction period is longer, and wall pours the more site operation personnel of needs, and manual labor amount is larger, construction
Human cost is high, and template can not be reused, and one side material compares waste, and another aspect efficiency of construction is not high.Secondly,
The structure of barricade is main and wall carries on the back the filling body material of backfill and level of ground water and has close relationship, particularly runs into heavy showers
When, the level of ground water that filling body is carried on the back with wall rises sharply, and larger threat be present to the stability of barricade.
The content of the invention
The purpose of the present invention is that to solve the above problems and provides a kind of L-type concrete guard wall.
The present invention be achieved through the following technical solutions above-mentioned purpose, a kind of L-type concrete guard wall, including main part and
Tenon part, the main part include bottom plate, main floor, riser, side rib plate and framework of steel reinforcement, and the bottom plate is provided with vertical
Plate, main floor and side rib plate, the main floor are located at the centre position of plate upper surface, and the side rib plate has two, the side
Floor is located at the left and right sides of main floor, and the lateral surface of the side rib plate is overlapped with the left and right side of bottom plate, set on the riser
There are four water seepage holes, the side rib plate is provided with a water seepage hole, and the Tenon part includes the first tenon, the first tongue-and-groove, the
Two tenons and the second tongue-and-groove, first tenon and the first tongue-and-groove are respectively provided on the side of left and right two of riser, and described second
Tenon and the second tongue-and-groove are respectively provided on the side of left and right two of bottom plate.
Preferably, the riser, bottom plate, main floor and side rib plate are frameworks of steel reinforcement in a mold by concreting
Integrally formed structure.
Preferably, the main floor pours using cable-stayed type framework of steel reinforcement as framework, and the section of framework of steel reinforcement is two
Triangle sets are into " L " shape.
Preferably, the riser, bottom plate, main floor and side rib intralamellar part are provided with framework of steel reinforcement, the outside of the side rib plate
Face is provided with four reinforcing bar end upsets.
Preferably, main floor and the side rib plate is for " L " shape, and the riser is perpendicular to bottom plate, the side rib plate two
Individual right-angle side is connected with riser and bottom plate respectively, and described two right-angle sides of main floor are connected with riser and bottom plate respectively.
Preferably, four water seepage holes on the riser are respectively between main floor and two side rib plates.
Preferably, the first tongue-and-groove of first tenon of a L-type concrete guard wall and another L-type concrete guard wall
Between can form gap cooperation, the of second tenon of a L-type concrete guard wall and another L-type concrete guard wall
Gap cooperation can be formed between two tongue-and-grooves.
Compared with prior art, the present invention has the advantages that：A kind of L-type concrete guard wall, it is pre- to carry out modularization
System, small volume, transhipment is convenient, is easy to combine, is compared to traditional reinforcement placing of formwork at the construction field (site) and pours wall again, this
Invention uses more convenient.Secondly, smart structural design of the present invention, triangle skeleton structure are meeting the feelings of same intensity requirement
More save concrete material than traditional wall that pours under condition, and on side rib plate lateral surface reinforcing bar end upset design, reinforcing bar can be made
Connection effect between skeleton and concrete is more preferable.Also, due to being equipped with water seepage hole on riser and side rib plate, when running into strong drop
During rain, draining can be played a part of, the level of ground water for reducing wall back of the body filling body rises sharply, the threat to the stability of barricade.And
And the present invention sets joinery and its construction so that the first tenon that multiple L-type concrete guard walls pass through a barricade in practice of construction
Second tongue-and-groove phase of the second tenon and next barricade of the mutual cooperation of the first tongue-and-groove and a barricade with next barricade
Mutually coordinate to cause each concrete guard wall to be connected, so that barricade is overall more stable.
