Abstract
The utility model belongs to the field of construction engineering, and discloses a novel cofferdam fore shaft steel sheet pile. The novel cofferdam fore shaft steel sheet pile comprises a side board panel, a large side board rib, a small side board rib, a guiding ring and an internal supporting frame. The novel cofferdam fore shaft steel sheet pile is characterized in that the side board panel is composed of a plurality of partitioning block side plates, and the partitioning block side plates are in bolted connection and fore-shaft connection to be used in an alternative mode. The fore-shaft connection is the connection of a son lock and a master lock in a matching mode, the son lock is connected with the side board panel through a stiffening plate and a connecting plate, the master lock is connected with the side board panel through the stiffening plate, and a son lock buckle and a master lock buckle are respectively made of seamless steel pipes of two different models. The novel cofferdam fore shaft steel sheet pile is simple and easy to splice and install, accurate in positioning controlling, good in stability, convenient and fast to fold and good in water-sealing effects.
Description
Technical field
The utility model belongs to building engineering field, particularly a kind of novel cofferdam fore shaft steel sheet pile, assembly unit and simple installation, positioning control is accurate, good stability, close up convenient and water sealing effect good.
Background technology
Steel sheet-pile cofferdam is the building and the temporary structure of bridge foundation construction, and still shared status is quite important really in foundation construction.It provides waterproof, anti-native effect for the construction on basis, also will prevent from sometimes to wash away and come down.
Cofferdam construction technology in the present water is used more end double-walled steel bushing box technology and the Larsen steel sheet-pile cofferdam technology of having or not.Wherein the main constructing operation of steel sheet pile cofferdam construction technology has that steel sheet pile sets, support in the cofferdam, concrete back cover, steel sheet pile pull out etc.Different construction technologies can be different on the order of concrete construction.Because steel sheet-pile cofferdam is simple in structure, construction is simple and easy, the duration is short, cost is low and quality is easy to advantages such as control.It is very extensive to make that steel sheet-pile cofferdam uses in silt, clay and mucky soil.
No end double-walled steel bushing case required precision when casing is transferred commonly used is higher, and the difficulty of correction is big.And the Larsen steel sheet-pile cofferdam needs monolithic to insert to beat, and it is bigger to close up difficulty.
Summary of the invention
In order to overcome above-mentioned defective of the prior art, that the utility model provides a kind of and can make the assembly unit of steel sheet pile easy, transferred is simple, close up novel cofferdam fore shaft steel sheet pile convenient and that water sealing effect is good.
A kind of novel cofferdam fore shaft steel sheet pile comprises side plate panel, the big riblet of side plate, lead ring, inner support frame, it is characterized in that described side plate panel is made up of a plurality of piecemeal side plates, connects to be connected with fore shaft by bolt between the piecemeal side plate to be used alternatingly.
Further, described fore shaft is connected to the son lock and female lock is connected, be connected with junction plate by stiffener between son lock and side plate panel, be connected by stiffener between female lock and side plate panel, son lock snap close and mother lock snap close and are made by the seamless steel pipe of two kinds of models respectively.
Reliable for guaranteeing fore shaft lock water, described son lock snap close closely links to each other with female lock snap close, and son lock and the junction design of female lock have water shutoff storehouse, the tonerde shutoff of water shutoff storehouse.
Side plate panel of the present utility model is consistent with the conventional sleeve cofferdam on structure and size, and the piecemeal side plate connects by fore shaft at the scene.For making things convenient for the dismounting in cofferdam, the cofferdam side plate can be divided into two joints up and down, the degree of depth that meets water of two joints needs to decide according to concrete engineering properties, connects by bolt between two joints up and down, during dismounting, unclamps bolt, will go up the joint side plate and remove.
The key position of novel cofferdam fore shaft steel sheet pile technology is a fore shaft.Son lock snap close and female lock snap close are made by the seamless steel pipe of two kinds of models respectively.Steel pipe is all elongated setting on every joint cofferdam.During construction, can adjust verticality, the plan-position of side plate, and play important sealing effect by fore shaft.
The beneficial effects of the utility model: side plate assembly unit and simple installation, positioning control is accurate, good stability, close up convenient and water sealing effect good.
Description of drawings
Fig. 1 is the piecemeal side plate schematic diagram of the side plate panel of the utility model specific embodiment.
Fig. 2 is sub-lock construction schematic diagram.
Fig. 3 is female lock construction schematic diagram.
Fig. 4 is the fore shaft connection diagram.
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Novel cofferdam of the present utility model fore shaft steel sheet pile comprises side plate panel 1, the big riblet of side plate, lead ring, inner support frame.
Shown in Fig. 2-4, fore shaft between the side plate panel is connected to son lock 2 and female lock 3 is connected, be connected with junction plate 22 by stiffener 21 between son lock 2 and side plate panel, be connected by stiffener 31 between female lock 3 and side plate panel, son lock snap close 23 and female snap close 32 of locking are made by the seamless steel pipe of two kinds of models respectively.
Reliable for guaranteeing fore shaft lock water, described son lock snap close 23 closely links to each other with female lock snap close 32, and son lock and the junction design of female lock have water shutoff storehouse 4, the tonerde shutoff of water shutoff storehouse.
Side plate panel of the present utility model is consistent with the conventional sleeve cofferdam on structure and size, and the piecemeal side plate connects by fore shaft at the scene.For making things convenient for the dismounting in cofferdam, the cofferdam side plate can be divided into two joints up and down, the degree of depth that meets water of two joints needs to decide according to concrete engineering properties, connects by bolt between two joints up and down, during dismounting, unclamps bolt, will go up the joint side plate and remove.
The key position of novel cofferdam fore shaft steel sheet pile technology is a fore shaft.Son lock snap close and female lock snap close are made by the seamless steel pipe of two kinds of models respectively.Steel pipe is all elongated setting on every joint cofferdam.During construction, can adjust verticality, the plan-position of side plate, and play important sealing effect by fore shaft.
The beneficial effects of the utility model: side plate assembly unit and simple installation, positioning control is accurate, good stability, close up convenient and water sealing effect good.
