Abstract
The utility model discloses a steel plate pile fore shaft structure which belongs to the technical field of the building engineering. A lock catch structure disclosed by the utility model comprises a male lock catch and a female lock catch which are mutually buckled, wherein an end part on the male lock catch, which is near the female lock catch, is connected with a round pipe used for grouting, and one end of the round pipe is sealed. The steel plate pile fore shaft structure has the advantages of simple structure and good waterstop effect, the problem that a water-proof material is difficult to fill can be favorably solved, and the construction quality is guaranteed.
Description
Technical field
The utility model relates to the locking notch structure of steel sheet pile, belongs to the technical field of construction work.
Background technology
Steel sheet pile often is used to building foundation pit, tunnel, side slope, dock, harbour, river levee, and field such as bridge pier cofferdam.Because steel sheet pile is green, rapid construction, steel sheet pile is used for protection such as cofferdam more, engineering blocks water.Therefore, in this case, waterproof becomes higher requirement.In the middle of existing steel sheet pile waterproof measure, mainly contain following several kinds of forms:
1, filled and process agent, cost is higher.
2, paste the magnetic sealing rod.This type construction rapidly, and is easy to operate, but expense is higher.
3, smear pitch, play waterproof action.This type operation is that one deck pitch is respectively brushed in both sides in the steel sheet pile fore shaft, and its surface can not done soon, needs nature, slowly solidifies.
4, the filling film plays waterproof action.
5, the way that the steel sheet pile leak stopping is general is with fillers such as cotton-wool, butter filling seam in steel sheet pile injection process.
More than several kinds of waterproof measures or expense is very high, or waterproof effect is not ideal, perhaps construction is inconvenient.Particularly when steel sheet pile does not have free face, can't accomplish choke material especially at steel sheet pile fore shaft place.Present steel sheet pile mainly is to solve through smearing waterproofing materials in order to overcome the problem of sealing, but the waterproofing materials of in the piling process, smearing is very easily owing to the friction between pile body or stake soil comes off the waterproof effect reduction.And the good waterproof of adhesion property is smeared material, and like polyurethane, magnetic sealing rod etc., its price is very expensive again.Therefore, present steel sheet pile sealing is mostly in piling, the materials such as filling cotton-wool, butter toward the fore shaft place.All can there be certain influence in this to safety of construction quality and technician etc.
Summary of the invention
The utility model purpose provides a kind of simple in structure, and stagnant water effect is good, can be good at solving waterproofing materials and fills difficult problem, guarantees the steel sheet pile locking notch structure of construction quality.
A kind of steel sheet pile locking notch structure, said locking notch structure are pin thread, the box of mutual snapping, and the end near box on the pin thread connects the pipe that is used for slip casting, the end sealing of pipe.
Arrange several circular holes on the sidewall of the utility model pipe.
Distance between the utility model circular hole is 0.5m.
The utility model adopts technique scheme, compared with prior art has following advantage: the utility model can effectively solve the problem that the waterproofing materials that when the steel sheet pile waterproof, runs into is filled difficulty.In general, steel sheet pile will reach good waterproof effect, just should carry out particular processing at the fore shaft place.The utility model straight forming pours into waterproofing materials toward pipe the inside again after piling finishes.The range of choice of the waterproofing materials of this moment wants much extensive, can select some expansion characters good and the less demanding product of adhesiveness needn't be worried the problem that material comes off in the piling process.In addition, the perfusion waterproofing materials carries out after piling finishes, and in the safety that has guaranteed operating personnel, has also guaranteed the quality and the efficient of piling to a certain extent.For nonvolatil steel sheet pile construction, then can carry out slip casting at the fore shaft place, reach the purpose of " forever " sealing.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model:
As shown in Figure 1, a kind of steel sheet pile locking notch structure, said locking notch structure are pin thread 1, the box 2 of mutual snapping, and the end near box 2 on the pin thread 1 connects the pipe 3 that is used for slip casting, the end sealing of pipe 3.
Arrange several circular holes on the pipe 3 of the utility model.
Distance between the circular hole of the utility model is 0.5m.
Cleared up the steel sheet pile surface before the utility model construction, steel sheet pile is tested and proofreaied and correct.The place coats sliding agent at the steel sheet pile fore shaft, the convenient connection.To the different model steel sheet pile, adopt the mode of singles or two doubles, steel sheet pile is squeezed into.Stake is poured into waterproofing materials, perhaps slip casting after squeezing into and finishing in pipe.Treat that perfusion reaches when necessarily requiring, piling finishes.When secondary uses, after steel sheet pile extracted, can the bottom of pipe be cut, clean steel stake surface and fore shaft carry out the check and the correction of steel sheet pile again.
Claims (3)
1. a steel sheet pile locking notch structure is characterized in that said locking notch structure is pin thread (1), the box (2) of mutual snapping, and the end that pin thread (1) is gone up near box (2) connects the pipe (3) that is used for slip casting, the end sealing of pipe (3).
2. steel sheet pile locking notch structure according to claim 1 is characterized in that arranging on the sidewall of above-mentioned pipe (3) several circular holes.
