Abstract
The utility model discloses a novel hasp steel pipe cofferdam structure, include the steel -tube framework who constitutes by a plurality of main steel pipes the pipe wall of main steel pipe has a I -steel along the welding of pipe diameter orientation, and it has the steel pipe of connection to weld in another pipe wall department that corresponds the main steel pipe of side with the I -steel, connect and to be provided with a longitudinal opening groove on the lateral surface of steel pipe corresponding to the face of weld, arbitrary main steel pipe pass through on I -steel and another main steel pipe be connected the steel pipe connect fixed, the I -steel with be connected the packing of steel pipe junction and have a packing material, the utility model discloses simple structure, convenient for material collection, through welding and the I -steel of main steel pipe both sides and is connected steel pipe interconnect and forms steel -tube framework, the I -steel with be connected the packing of steel pipe junction and have the saw -dust, can play the fine effect of blocking water, seal effectually, steel pipe convenient to detach can reuse.
Description
Technical field
This utility model relates to foundation engineering and the hydraulic engineering technical field of science of bridge building, is specifically related to a kind of Novel lock catch steel pipe cofferdam structure.
Background technology
Cofferdam refers in the foundation engineering and hydraulic engineering construction of bridge, for building permanent water conservancy projects, and the provisional building enclosure built.Its effect is to prevent what water and soil from entering building to build position, in order at cofferdam internal drainage, and excavation pit builds building.Generally being mainly used in foundation engineering and the waterwork of bridge, except the part as formal building, cofferdam is removed after being typically in being finished.
The effect that prior art prevention moisture enters cofferdam is bad, it is necessary to water pump is a large amount of drainings from cofferdam, and working security is not high.
Utility model content
(1) to solve the technical problem that
In order to overcome prior art not enough, it is proposed that a kind of Novel lock catch steel pipe cofferdam structure, inflow is greatly reduced, and water pump displacement from cofferdam is greatly decreased, and working security is higher, makes simple, draws materials conveniently.
(2) technical scheme
Of the present utility model it is achieved through the following technical solutions: the utility model proposes a kind of Novel lock catch steel pipe cofferdam structure, including the steel pipe frame being made up of some main steel pipes, tube wall at described main steel pipe is welded with an I-steel along caliber direction, it is welded with a joint steel pipe at another tube wall place with the main steel pipe of I-steel respective side, described joint steel pipe is corresponding to being provided with a longitudinal opening groove on the lateral surface of solder side, arbitrary main steel pipe is connected fixing by I-steel with the joint steel pipe on another main steel pipe, it is filled with fill material in I-steel and joint steel pipe junction.
As further improvement, described longitudinal opening well width is slightly larger than the perpendicular rib width of I-steel.
As further improvement, described fill material is wood flour.
(3) beneficial effect
This utility model, relative to prior art, has the advantages that
A kind of Novel lock catch steel pipe cofferdam structure that this utility model is mentioned, its simple in construction, draw materials conveniently, it is interconnected to form steel pipe frame by the I-steel of welding and main steel pipe both sides and joint steel pipe, it is filled with wood flour, it is possible to play good resistance effect, good sealing effect in I-steel and joint steel pipe junction, steel pipe is readily accessible, it is possible to recycling.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
The main steel pipe of 1-；2-I-steel；3-joint steel pipe；4-fill material；31-longitudinal opening groove.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
A kind of Novel lock catch steel pipe cofferdam structure as shown in Figure 1, including the steel pipe frame being made up of some main steel pipes 1, an I-steel 2 it is welded with along caliber direction at the tube wall of described main steel pipe 1, it is welded with a joint steel pipe 3 at another tube wall place with the main steel pipe 1 of I-steel 2 respective side, described joint steel pipe 3 is corresponding to being provided with a longitudinal opening groove 31 on the lateral surface of solder side, arbitrary main steel pipe 1 is connected fixing by I-steel 2 with the joint steel pipe 3 on another main steel pipe 1, is filled with fill material 4 in I-steel 2 and joint steel pipe 3 junction.
Wherein, described longitudinal opening groove 31 width erects rib width slightly larger than I-steel 2；Described fill material 4 is wood flour.
A kind of Novel lock catch steel pipe cofferdam structure that this utility model is mentioned, it is when specifically used, and each main steel pipe 1 opposite sides is respectively welded a joint steel pipe 3 and an I-steel 2, and this is one and connects unit；The joint steel pipe 3 that one connects on unit is sheathed on another and connects on the cross rib of I-steel 2 lateral surface on unit, longitudinal opening groove 31 card on joint steel pipe 3 is embedded in the perpendicular rib place in the middle part of I-steel 2, it is cross-linked successively, some connection unit form steel pipe frame, effective Fence structure can be formed in water conservancy construction process, joint steel pipe 3 is at the wood flour filled with I-steel 2 joint gap place, can play, after the wet water soaking of wood flour, the sealing effectiveness that well blocks water, most importantly wood flour is drawn materials relatively wide, and low price.
This utility model simple in construction, facilitates installing/dismounting, it is possible to recycling, construction effect is good, it is ensured that underwater construction safety.
Embodiment described above is only that preferred implementation of the present utility model is described, and not design of the present utility model and scope is defined.Under the premise without departing from this utility model design concept; various modification that the technical solution of the utility model is made by this area ordinary person and improvement; protection domain of the present utility model all should be dropped into, the technology contents that this utility model is claimed, all record in detail in the claims.
