Description
Technical Field
The utility model belongs to the technical field of pile foundation engineering of various building structure systems, and particularly relates to a concrete pile and a continuous seepage-proofing water-stop wall spliced by the concrete pile.
Background
And the large underground buildings, side slopes, tunnels, port and dock walls, river bank protection and the like are treated, and temporary or permanent enclosure is carried out on the foundations of the buildings or the surrounding buildings during construction of the buildings.
The enclosures commonly used at present have the following forms: the first method is to insert a plurality of reinforced concrete circular piles into soil to form a retaining wall after combining cement stirring piles, and the second method is to insert a plurality of T-shaped piles or cement stirring piles manufactured by an SMW construction method into soil to form a retaining wall.
The second is to use steel sheet piles and the combination wall mode, the structure of which is like that of the protection wall disclosed in Chinese patent application No. CN200680009749.6 (bulletin No. CN 101146960A) and Chinese patent application No. CN200480018307.9 (bulletin No. CN 1813108A). The carrier elements used in both of these published patent applications are hot rail manufactured, and the expensive roll set is prohibitively expensive to manufacture by rough rolling, finish rolling, and the like, to form such a head-shaped connecting tail.
The third is a bank protection wall formed by adopting rectangular piles, H-shaped supporting piles or U-shaped sheet piles (also called as a U-shaped sheet pile) which are sequentially connected through a rib groove inserting structure, wherein the pile body is provided with two opposite splicing surfaces for splicing, the rectangular piles are taken as an example, the splicing surfaces are two opposite side surfaces, the U-shaped sheet piles are taken as an example, and the splicing surfaces are the side surfaces of two opposite flanges. For example, a Chinese patent of the utility model, "H-shaped support pile connection structure" with the patent number ZL201320461012.5 (bulletin number CN 203559411U) discloses an H-shaped pile for use in a maintenance wall. For example, chinese patent No. ZL201220102189.1 (bulletin No. CN 202543900U) discloses a U-shaped sheet pile with a rib groove insertion structure, which is mainly improved by filling rubber or plastic caulking sealing materials in the gaps of the rib groove insertion structure. For example, chinese patent No. ZL201210069105.3 (bulletin No. CN 102650127B) discloses a U-shaped sheet pile with a T-shaped through groove formed on a lower flange of one side, wherein the lower flange of the other side is combined with i-steel, half of the i-steel is left outside the pile body structure, and half of the i-steel is embedded into the pile body structure, and when the sheet pile is under construction, adjacent sheet piles are assembled into a whole through the i-steel and the T-shaped through groove, and then are mechanically driven.
The continuous wall formed by splicing the concrete piles through the inserting and matching structure of the rib grooves has very high requirement on pile driving precision, the rib groove structures are required to be mutually corresponding and mutually inserted after pile driving, but in the actual construction process, the rib groove structures and the pile driving structure are difficult to be mutually corresponding and mutually inserted and matched, in order to ensure good water stop, rubber strips are required to be arranged at the joint for sealing, the rubber strips are easy to wear and influence the water stop effect, and if the adjacent two piles are staggered more, the rubber strips cannot form good sealing. The waterproof wall formed by the I-shaped steel connection mode has the advantages that adjacent sheet piles are assembled into a whole through the I-shaped steel and the T-shaped through groove, the T-shaped through groove is small in clearance, the concrete pile is heavy, the I-shaped steel on the other concrete pile is ensured to be inserted into the groove during lifting, the I-shaped steel is very difficult to be inserted into the groove, when piling, if the adjacent two piles are dislocated, the I-shaped steel or the concrete pile is damaged, and a bit of deviation is unavoidable in the piling process, so that the scheme is not a feasible scheme in practice.
In view of the above, the existing manner for constructing the spliced continuous impermeable water stop wall needs to be further improved.
