Description

Drilling, guiding and hammering integrated machine in PHC (prestressed high-strength concrete) pipe pile

Technical Field

The invention relates to the technical field of pile foundation construction equipment, in particular to a drilling, guiding and hammering integrated machine for a PHC pipe pile.

Background

The existing pile foundation construction generally comprises a steel pile, a cast-in-situ bored pile and a PHC (prestressed high-strength concrete) pipe pile.

The steel pile adopts steel materials, so that the hardness and the toughness of the steel pile are good, the pile materials cannot be damaged by large hammering force, meanwhile, the steel material has high strength and small section, the penetrating capability of the steel pile to a soil layer is good, and the quality of the steel pile penetrating through a thick sandy soil layer is guaranteed. However, the steel piles are expensive in manufacturing cost, so that more expensive steel materials are driven under the ground, which is difficult to bear by general owners, and the steel piles are less and less adopted in the current engineering foundation treatment.

The cast-in-situ bored pile can penetrate through most soil layers, and is a solution scheme which is most used for penetrating through thick sandy soil layers and the like at present. However, the cast-in-situ bored pile has the following disadvantages:

1) and because the soil squeezing effect is not generated, the bearing capacity of a single pile with the same diameter is lower compared with that of a PHC pile.

2) The pile sinking quality is restricted by the site construction conditions, the site pore-forming, the reinforcement cage manufacturing and the concrete pouring procedures are complex, the construction is complicated, and the pile-forming quality control is difficult.

3) The construction cost is lower than that of a steel pipe pile and is obviously higher than that of a PHC pile.

4) The construction speed is limited by equipment, and the pile sinking speed of each pile to each pile foundation is slower than that of a PHC pile.

5) The dirty condition of mud full flow can appear in drilling bored concrete pile building site, and the building site is drawn water everywhere and the busy scene of mound fortune soil.

6) If a karst cave or an underground river and the like appear in a pile foundation soil layer, a large amount of concrete is over-poured, and great economic loss is caused.

Compared with the traditional concrete cast-in-place pile, the PHC tubular pile has the advantages of visual quality, convenience in inspection, low manufacturing cost, easiness in ensuring of pile forming process quality, short construction period, environmental friendliness and the like, and becomes the main force and development direction of the existing pile for construction.

In practical engineering, a soft soil layer (weak subjacent layer) exists in a soil layer, and because the engineering has high requirements on settlement control, a soil layer below the soft soil layer is required to be used as a bearing layer, so that the PHC pipe pile generally needs to penetrate through a soft soil layer and a hard soil layer above the soft soil layer, and is generally a sandy soil layer. When the thickness of the sandy soil layer is large (generally more than 10m), particularly for the PHC tubular pile with a large diameter (generally more than 120 cm), due to the soil plug effect, pile sinking of the PHC tubular pile with the large diameter is very difficult no matter hammering and static pressure pile sinking processes are adopted. For projects which generally need to penetrate through thicker sandy soil layers (generally more than 10m) and have longer pile lengths (generally more than 40m), most of the traditional foundation treatment methods adopt steel piles or cast-in-situ bored piles.

The invention patent with application number of CN200710156471.1 in the prior art discloses a construction process for hammering a PHC tubular pile into rock through whole process pre-leading holes, which adopts a rotary pile machine with a long spiral drill rod, firstly pre-leading holes on the pile foundation in the whole process, then injecting yellow mud into the pre-leading holes, forming a mud protective wall in the holes, and finally hammering the PHC tubular pile to a designed depth by using a hammering pile machine; in practical engineering, in particular large-scale railway bridge engineering, a single-pier bearing platform pile group pile foundation is mostly adopted, a plurality of piles are arranged below a bearing platform, and some piles have inclination (inclined piles), and the method has the following defects:

1) because two equipment of rotation type stake machine, hammering stake machine are adopted, accomplish the lead hole of PHC tubular pile and the construction of hammering respectively, it is difficult to guarantee its same gradient, and the construction precision is relatively poor.

2) Due to the fact that a site for pile group construction is narrow, a rotary pile driver and a hammering pile driver are adopted, the coordination difficulty of the two devices is high, and influences on construction cost, quality, safety, progress and the like are large.

Therefore, it is necessary to design a new PHC pile construction equipment to solve the above problems.
