Embodiment Construction

[0030] The present invention will be further described in detail in conjunction with a certain bridge engineering project using lock steel pipe pile cofferdam waterstop construction as an example.

[0031] The bridge auxiliary pier cap is 37m long, 10.5m wide and 4m high, and the total square capacity of the cap is 1372m 3 , Locked steel pipe piles are used as water-stop cofferdams during construction. The water-stopping construction process of lock steel pipe piles is as follows: design and process TC type lock steel pipe piles → insert and drive lock steel pipe piles → lock cleaning → insert waterproof cloth belt and grouting pipe into the lock → adjust low strength and high strength Mortar→mortar injected into the lock→health preservation

[0032] 1. During construction, design the lock as a TC-type lock for insertion and punching. The steel pipe adopts a diameter of Φ800*10mm, the T-shaped male port of the lock is cut in half with I16 I-shaped steel, and the C-shaped fem...

Abstract

The invention relates to a deepwater foundation construction technology for bridges, discloses a water-retaining construction technology for locked steel pipe piles and belongs to the field of engineering construction. The water-retaining construction technology specifically comprises the steps of machining, inserting and driving the TC type locked steel pipe piles, cleaning locking openings, inserting waterproof cloth belts and grouting pipes into the locking openings, preparing mud, injecting the mud into the locking openings and curing the mud. According to the invention, for overcoming the shortcomings and constraints in the prior art, the TC type locking openings are designed for being matched with mortar, constructing, inserting and driving are convenient, the water-retaining performance is good, the construction efficiency is high, and the effect is good in construction of deepwater locked cofferdams. The TC type locking openings formed by combining H-shaped steel and steel pipes are adopted and have the advantages that embedding is convenient, the strength is high and the water-retaining effect is good. The low-strength slight-expansion mud is poured into waterproof geotextile in the middle of the locking openings for retaining water.

Description

technical field [0001] The invention relates to a bridge deep-water foundation construction technology, in particular to a water-stop construction technology for a locking steel pipe pile cofferdam, which belongs to the field of engineering construction. Background technique [0002] With the development of my country's engineering construction field, the deep-water construction technology of interlock steel pipe pile cofferdam will be applied and promoted to a certain extent. The locking cofferdam has the advantages of fast construction speed, high cofferdam rigidity, and the steel pipe column can be turned over many times. [0003] But the water-stop problem of the lock is still an important factor restricting its technical promotion. At present, the use of interlock steel pipe pile cofferdams for foundations in water is less restricted due to the difficulty of water stop, and after water stop, it is necessary to consider that the steel pipe piles can be pulled out smooth...
