Description

Point type direction prevention of seepage concrete pile and river course shore protection

Technical Field

The utility model belongs to the technical field of the pile foundation engineering of all kinds of building structure systems, especially, relate to a point type direction prevention of seepage concrete pile.

Background

The protective wall formed by splicing the precast concrete piles is widely applied to the renovation of the quay walls of ports and docks and river revetment, for example, the Chinese utility model patent with the patent number of ZL201220102189.1 (the publication number of CN 202543900U) discloses a U-shaped sheet pile with a rib groove inserting structure, and the improvement point is that rubber or plastic caulking sealing materials are filled in the gap of the rib groove inserting structure. For example, as a U-shaped sheet pile with a prefabricated steel concrete mixed structure, which is disclosed in the invention patent No. ZL201210069105.3 (publication No. CN 102650127B) of china, a U-shaped sheet pile with a T-shaped through groove formed in the lower flange of one side is combined with an I-shaped steel, half of the I-shaped steel is left outside the pile body structure and half of the I-shaped steel is embedded into the pile body structure, and when the sheet pile is sunk for construction, adjacent sheet piles are assembled with the T-shaped through groove into a whole through the I-shaped steel, and then the pile is sunk mechanically. Insert the diaphragm wall that joins in marriage concrete pile concatenation formation of structure through the muscle groove, it is very high to the required precision of piling, need guarantee that pile back muscle groove structure will correspond each other and insert each other, then in actual work progress, both hardly correspond and insert each other and join in marriage, the junction has certain gap, run into the rainwater day, earth is under rivers wash, easily run off the river course through the gap, long-time bank dyke soil and water can run off, consequently, need additionally do the prevention of seepage and pass through the processing, still need set up the rubber strip in the junction and seal, the rubber strip easily wears and influences the prevention of seepage and pass through the effect, if two adjacent dislocation are more, the rubber strip also can not form better blocking. The waterproof wall formed by connecting the H-shaped steel is required to be assembled into a whole by the H-shaped steel and the T-shaped through groove, the T-shaped through groove gap is very small, the concrete pile is very heavy, the H-shaped steel on the other concrete pile is ensured to be inserted into the insertion groove when the concrete pile is lifted, the H-shaped steel or the concrete pile is very difficult to damage, and the H-shaped steel or the concrete pile is inevitably deviated a bit in the piling process if the two adjacent piles are dislocated a bit during piling, so the scheme is not a feasible scheme in practice.

Therefore, the applicant applies for a water stopping structure between two concrete piles according to the Chinese utility model patent with the patent number ZL202020040562.X (with the publication number CN 211898319U), the water stopping structure is inserted into an embedded pipe on one side of an adjacent concrete pile through a water stopping film belt on one side of the concrete pile, an anti-seepage surface is formed between two splicing surfaces of a concrete pile body through grouting, the water stopping film belt is a flexible belt body, if a fire fighting belt can be adopted, the water stopping film belt is a flexible tubular part and can be randomly deformed, even if the two adjacent piles have large gaps or are mutually staggered, the other end of the water stopping film belt enters the embedded pipe through the gap. But this design has a pain point yet, because of the sealing membrane area is flexible, can not form rigid connection with the embedded pipe after the pile driving, leads to the interval between two adjacent piles can be great after the pile driving, also easily makes the sealing membrane area probably can not fully get into in the embedded pipe.

In summary, the existing method for constructing the spliced continuous impermeable revetment needs to be further improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the first technical problem that a point type direction prevention of seepage concrete pile is provided to above-mentioned prior art current situation, can form good prevention of seepage effect between the protecting wall that adopts this concrete pile concatenation to form, also can guarantee simultaneously that two piles can better mutual opposite insertion when the concatenation, it is firm to splice, even there is great dislocation in the work progress for two adjacent concrete piles, also can conveniently form seepage prevention structure between two concrete piles, do benefit to the construction.

The anti-seepage film belt is divided into multiple sections, so that the phenomenon that a single-section anti-seepage film belt is too long (the part of the single-section anti-seepage film belt which is too long and is filled with the filler is too soft) is avoided, and the anti-seepage film belt filled with the filler is favorably inserted into the second cavity of the embedded pipe.

The seepage prevention mainly plays a role in the bank, namely the seepage prevention is needed to be carried out on the part of the concrete pile exposed out of the river bed, the part inserted into the ground is not needed to be designed for seepage prevention, so that the seepage prevention film belt and the embedded pipe preferably extend downwards from the top surface of the pile head of the concrete pile body.

Preferably, the first splicing surface is provided with a protrusion along the length direction of the concrete pile body, the impermeable film strip exposes out of the protrusion, the second splicing surface is provided with a groove matched with the protrusion along the length direction of the concrete pile body, and the gap of the embedded pipe exposes out of the bottom surface of the groove. Because the bulge or the groove is of a standard design on the concrete pile, if the bulge or the groove needs to be arranged on the concrete pile, the impermeable membrane belt and the embedded pipe are arranged at the optimal position.

The following two types of pile types are suitable for the concrete pile, but the pile type is not limited to the following two types of pile types, and may be a pile for a bank protection impermeable water stop wall such as a T-shaped pile, a concrete slab pile, a centrifugal pile, or the like.
