Abstract
The invention discloses a construction method of a foundation slag, which comprises the steps: firstly, constructing an under layer; secondarily, constructing a reinforcing layer of a later casting zone, a waterproof layer, a waterproof protection layer, concrete structures at two sides of the later casting zone and a concrete structure of the later casting zone in sequence, wherein the reinforcing layer of the later casting zone is positioned below the later casting zone and of an integral structure formed by steel plates laid in the length direction of the later casting zone, two sides of the steel plates both exceed the later casting zone in the width direction of the later casting zone, and the adjacent steel plates are welded in the length direction of the later casting zone. In the invention, the integral steel plate structure is used as the reinforcing layer of the later casting zone and used for substituting for a reinforced concrete structure, thus the structure and construction procedures of the reinforcing layer of the later casting zone can be simplified, and the work amount and labor force can be reduced. After the under layer is constructed, the steel plates are placed at the designed positions, thus the construction is convenient, the work amount is reduced greatly, the working efficiency is improved, the construction time is reduced, the project cost is decreased and the economic benefits and the social benefits are remarkable.
Description
Technical field
The present invention relates to a kind of job practices of sole plate.
Background technology
At present, the sole plate Structural Engineering can be provided with the ater-casting for solving differential settlement or reducing temperature shrinkage crack problem.The ater-casting is meant in cast-in-place whole reinforced concrete structure, only the provisional band shape seam of retaining in construction period plays the effect of digestion sedimentation shrinkage strain, according to requirement of engineering, after keeping certain hour, again with the closely knit structure that becomes continuous integral body of concreting.At present, adopt the engineering that the ater-casting is set generally enhancement Layer to be set at the position, ater-casting.Enhancement Layer generally adopts reinforced concrete structure, and the earthwork of enhancement Layer position needs the local subsidence excavation, assembling reinforcement, and concreting, maintenance, time-consuming.Especially grade beam sinking position, the operation exception complexity.
Summary of the invention
The present invention provides a kind of job practices of sole plate for solving the technical problem that exists in the known technology, this job practices easy construction, and speed is fast, the efficient height, cost is low.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of job practices of sole plate; elder generation's construction cushion coat; the ater-casting enhancement Layer of constructing successively again; waterproofing course; fish tail and waterproof layer; the concrete structure of both sides, ater-casting and the concrete structure of ater-casting; described ater-casting enhancement Layer is positioned at the below of ater-casting; the integrative-structure that described ater-casting enhancement Layer is served as reasons and formed along the steel plate of ater-casting length direction laying; on the width of ater-casting; the both sides of described steel plate all exceed the ater-casting; on the length direction of ater-casting, adjacent described steel plate welding.
On the width of ater-casting, the every side of described steel plate exceeds the equal in length of ater-casting, and all more than or equal to 500mm.
Advantage and good effect that the present invention has are: the ater-casting enhancement Layer adopts the steel plate structure that forms one to replace reinforced concrete structure, has simplified the structure and the working procedure of ater-casting enhancement Layer, has reduced engineering quantity and labour; After cushion construction finishes, only need that steel plate is pressed the design attitude placement and get final product, easy construction, the workload that can lighten one's labor is greatly increased work efficiency, and reduces the engineering time, reduces engineering cost, economic benefit and obvious social benefit.
Description of drawings
The structural representation that Fig. 1 uses for the present invention.
Among the figure: 1, plain soil, 2, bed course, 3, the ater-casting enhancement Layer, 4, waterproofing course, 5, fish tail and waterproof layer, 6, the concrete structure of both sides, ater-casting, 7, the ater-casting.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of job practices of sole plate may further comprise the steps:
One) after being excavated at the bottom of the foundation ditch, the plain soil 1 of labor cleaning's foundation ditch, behind the check of foundation subsoil, construction cushion coat 2; After the construction of bed course 2 is finished, it is carried out maintenance; Measure the position of determining ater-casting 7, after the concrete for the treatment of bed course 2 reaches the intensity of designing requirement, 7 length direction is laid on the below of ater-casting 7 to the thick steel plate 3 of 5～20mm that width is wideer a meter than the ater-casting along the ater-casting, makes that steel plate 3 every sides are wide to go out ater-casting 500mm at least; 7 the length direction along the ater-casting adopts 45 ° of groove welding between the adjacent steel plate 3;
Two) concrete structure 6 of construction waterproof layer 4, fish tail and waterproof layer 5 and both sides, ater-casting successively, the concrete structure of the ater-casting 7 of constructing at last.
Although in conjunction with the accompanying drawings the preferred embodiments of the present invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
Claims (2)
1. the job practices of a sole plate; elder generation's construction cushion coat; construct the successively again concrete structure of ater-casting enhancement Layer, waterproofing course, fish tail and waterproof layer, both sides, ater-casting and the concrete structure of ater-casting; described ater-casting enhancement Layer is positioned at the below of ater-casting; it is characterized in that; the integrative-structure that described ater-casting enhancement Layer is served as reasons and formed along the steel plate of ater-casting length direction laying; on the width of ater-casting; the both sides of described steel plate all exceed the ater-casting; on the length direction of ater-casting, adjacent described steel plate welding.
2. the job practices of sole plate according to claim 1 is characterized in that, on the width of ater-casting, the every side of described steel plate exceeds the equal in length of ater-casting, and all more than or equal to 500mm.
