Abstract
The utility model discloses a construction joint structure of a concrete wall. The concrete wall comprises a plurality of concrete wall sections poured successively. Two adjacent concrete wall sections comprise a concrete wall section poured first and a concrete wall section poured later. The construction joint structure comprises a water-stopping steel plate embedded in the concrete wall section poured first, and the water-stopping steel plate is located in the middle of the position of a construction joint of two adjacent concrete wall sections. Part of the water-stopping steel plate is embedded in the concrete wall section poured first, and the other part of the water-stopping steel plate is poured in the concrete wall section poured later. The water-stopping steel plate is adopted in the construction joint and poured on the concrete wall section poured later by adopting a corbel-shaped sprue. The construction joint is compact in structure, good in water-stopping performance and free of leakage. Besides, the construction joint structure is simple and convenient to construct and low in cost.
Description
Technical field
The utility model relates to a kind of constuction joint structure, particularly relates to a kind of concrete wall constuction joint structure.
Background technology
Wen Feng mountains and rivers, Tangshan wheel hub Co., Ltd 4300 special heavy plate engineering-cyclone wells are circular underground structure, mainly by inside and outside tube; Platform, compositions such as slag runner, urceolus external diameter ￠ 14m; Urceolus wall thickness 1m, inner core external diameter ￠ 4.1m, inner core wall thickness 300mm; Absolute altitude-25.750m at the bottom of the base plate plate, base plate thickness 2m.Bed course C10 concrete, the cyclone well main body adopts the C30.P8 waterproof concrete, and back-grouting adopts C35.
The cyclone well urceolus adopts the reverse construction order, all skirt piles of construction earlier, treat its reach design strength after soil excavation to being preced with the beam absolute altitude, construction ring beam and first segment outer tube wall.Treat that intensity reaches the second joint earthwork of continued excavation, carries out the construction of second joint.The treatment of construction joints of the first segment barrel and the second joint barrel link position is to guarantee the whether key of seepage of outer tube wall during this sequence construction.
The utility model content
The utility model provides a kind of non-leakage concrete wall constuction joint structure for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of concrete wall constuction joint structure; This concrete wall comprises some joint concrete wall joints of first after-pouring; Adjacent two joint concrete walls joints comprise the concrete wall joint of formerly building and at the concrete wall joint of after-pouring; This constuction joint structure is included in pre-buried steel plate for sealing water in the said concrete wall joint of formerly building, and said steel plate for sealing water is positioned at the centre position at the constuction joint place of said adjacent two joint concrete walls joints; The part of said steel plate for sealing water is embedded in the said concrete wall joint of formerly building, and another part is cast in said in the concrete wall joint of after-pouring.
The concrete body that any side of the constuction joint that said two adjacent joint concrete walls save is coated with bracket shape.
Advantage and the good effect that the utlity model has are: through in constuction joint, adopting steel plate for sealing water and adopting bracket shape cast gate to be cast in the concrete wall joint of after-pouring, the structure of constuction joint is closely knit, and sealing property is good, and is non-leakage.And easy construction, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the concrete wall of 1, formerly building joint, 2, steel plate for sealing water, 3, at the concrete wall joint of after-pouring, 4, cast gate.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; A kind of concrete wall constuction joint structure; This concrete wall comprises some joint concrete wall joints of first after-pouring; Adjacent two joint concrete walls joints comprise the concrete wall joint 1 of formerly building and at the concrete wall joint 3 of after-pouring, this constuction joint structure is included in pre-buried steel plate for sealing water 2 in the concrete wall joint 1 of formerly building, and steel plate for sealing water 2 is positioned at the centre position at the constuction joint place of two adjacent joint concrete walls joints; The part of steel plate for sealing water 2 is embedded in the concrete wall joint 1 of formerly building, and another part is cast in the concrete wall joint 3 of after-pouring.
In order further to improve anti-permeability performance, the concrete body that any side of the constuction joint of two adjacent joint concrete wall joints is coated with bracket shape.
Above-mentioned concrete wall treatment of construction joints method, first pre-buried steel plate for sealing water 2 in the concrete wall joint 1 of formerly building makes steel plate for sealing water 2 be positioned at the centre position at the constuction joint place of above-mentioned adjacent two joint concrete walls joints; Save 3 tops at the concrete wall at after-pouring and install the cast gate 4 that facade is bracket shape, cast gate 4 is higher than the constuction joint that above-mentioned two adjacent joint concrete walls save; Build concrete from cast gate 4, being formed on the concrete wall joint 3 of after-pouring and in cast gate, forming facade is the concrete body of bracket shape, and the concrete body protrudes outside above-mentioned two adjacent joint concrete walls joints, and covers the constuction joint between them; The part of steel plate for sealing water 2 is embedded in the concrete wall joint 1 of formerly building, and another part is cast in the concrete wall joint 3 of after-pouring.
In the present embodiment, the concrete wall is a barrel, and cast gate 4 is an annular; Width is 200mm, is higher than constuction joint 300mm, is used to be cast in the concrete wall joint that the back forms; Make the concrete of building be easy to be filled into after the steel plate for sealing water 2 and be convenient to vibrate, thereby make concrete closely knit, guarantee the quality of constuction joint.After treating that concrete strength reaches designing requirement, the facade that will in cast gate, form is that the concrete body of bracket shape cuts, and with 1: 2 cement sand plaster.
If the concrete body that the above-mentioned facade that in cast gate, forms is a bracket shape does not influence the structure and the function of use of cyclone well, can it not cut, can save a large amount of people, material resources, speed up the work, can be used as the impervious reserve safeguard measure of constuction joint again.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the utility model.
