Abstract

The invention discloses a construction method for a composite pile. The method comprises the following steps: drilling a hole in a preset pile position to a set depth by using a drilling machine, and filling a gripping material into the drilled hole in a pressure filling way; inserting a precast pile into the drilled hole to finish construction of the composite pile, wherein the gripping material consists of one or more of cement, soil cement, cement mortar, fine stone concrete and a cement coal ash mixture meeting a pumping requirement, and the gripping material is in a liquid state; the pressure filling amount of the gripping material is 40-60 percent of the volume of the drilled hole. The construction method for the composite pile disclosed by the invention is easy, convenient and feasible, has the advantages of high quality, low construction cost and short construction period, and is very suitable to be applied to coastal engineering geology which has high underwater level and is soft on the upper part and hard on the lower part.

Description

A kind of construction method of composite pile
Technical field
The present invention relates to the pile foundation field in civil engineering, particularly a kind of construction method of composite pile.
Background technology
Due to the aspects such as soil nature, Processes and apparatus reason, belong to prefabricated (solid or hollow) stake of Squeezing Soil Pile, often there will be the not in place and long problem that differs greatly of stake of irregular pile body, have a strong impact on workmanship and there is great potential safety hazard.
In prior art, common composite pile is cement earth pile, after particularly adopting powder pressure spray process to complete, insert preformed pile again, form stiff composite pile, its follow-up construction of prefabricated piles difficulty is larger, theoretic composite pile high-bearing capacity, is but difficult to guarantee in practice.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides a kind of construction method of composite pile, this construction method is simple and easy to do, and quality is good, and cost is low, duration is short, is suitable for very much using in the engineering geology of coastal " phreatic high ", " upper soft lower hard ".
In order to solve above technical problem, the invention provides a kind of construction method of composite pile, comprising the steps:
1., in pre-fixed pile, utilize drill hole of drilling machine to set depth and press filling to bond material in boring;
preformed pile is inserted the construction namely completing composite pile in above-mentioned boring.
Technique effect: the present invention is combined with the advantage of two kinds of different process technology, can guarantee that construction of prefabricated piles puts in place, improves the supporting capacity of foundation pile, guarantees workmanship; Meanwhile, the present invention is simple and easy to do, and quality is good, and cost is low, and the duration is short, is suitable for very much using in the engineering geology of coastal " phreatic high ", " upper soft lower hard ".
The technical scheme that the present invention limits further is:
Further, the construction method of aforesaid composite pile, step 1. in, adopt long auger pressure fill with technique complete bond material pressure fill with, concrete operations are, complete boring back upwards carry the pumping of drilling rod limit bond material to boring in;
The present invention is first in the boring of default stake position, and limit is upwards proposed the pumping of drilling rod limit and bonded material in boring, has both eliminated soil compaction impact, and has also prevented the soil body collapse hole around stake holes, conveniently implants preformed pile pile body, and what improve preformed pile can application property; After engineering material coagulates firmly around preformed pile pile body, add the contact area of a side and surrounding soil, improve pile bearing capacity, ensure that workmanship, improve cost performance.
The construction method of aforesaid composite pile, it is liquid for bonding that material forms by one or more meeting in the cement of pumping requirements, cement-soil, cement mortar, fine-stone concrete and cement & fly ash mixture and bonded material; The present invention selects and commonly in pile foundation construction bonds material, and construction cost is effectively controlled, and cost performance is high.
The construction method of aforesaid composite pile, the pressure filling amount bonding material is the 40%-60% of borehole volume; The pressure filling amount bonding material is controlled in the present invention, not only avoid the material that bonds too much when pile body is put into and overflow boring, thus cause the waste of engineering material, that can not cause again the pile body whole body bonds material usage deficiency simultaneously, the compacted degree of pile peripheral earth is not up to standard, thus have impact on the quality of construction.
The construction method of aforesaid composite pile, step in, insertion that the inserted mode of preformed pile is hammering insertion, static pressure inserts or the vibrating hammer of employing band hydraulically operated fixture shakes, preformed pile bottom is inserted into boring bottommost.
The construction method of aforesaid composite pile, drilling depth is greater than preformed pile length 30-50CM, and fully contacting and fully extruding of pile body and pile peripheral earth, lower than boring surface 30-50CM, is guaranteed in pile body top, the compacted degree of pile peripheral earth reaches the requirement of design, and construction quality is guaranteed.
The construction method of aforesaid composite pile, preformed pile can select square pile, pile tube or Bamboo-shaped stake.
Accompanying drawing explanation
The structural representation of the composite pile of Fig. 1 designed by the present invention.
Detailed description of the invention
As shown in Figure 1, the construction method of a kind of composite pile that the present embodiment provides, comprises the steps: structure
in pre-fixed pile, utilize drill hole of drilling machine to set depth and press filling to bond material in boring, in practical operation, adopting long auger pressure to fill with technique and complete the pressure filling bonding material, concrete operations are, complete boring back upwards carry the pumping of drilling rod limit bond material to boring in;
It is liquid for bonding that material forms by one or more meeting in the cement of pumping requirements, cement-soil, cement mortar, fine-stone concrete and cement & fly ash mixture and bonded material, and the pressure filling amount bonding material is the 40%-60% of borehole volume;
preformed pile is inserted the construction namely completing composite pile in above-mentioned boring, in practice of construction, the inserted mode of preformed pile is hammering insertion, static pressure inserts or adopt the vibrating hammer of band hydraulically operated fixture to shake insertion, preformed pile bottom is inserted into boring bottommost;
In practice of construction, the predetermined depth of boring is greater than preformed pile length 30-50CM;
Utilize the construction method of the composite pile designed by the present invention, can complete in the construction of reality based on the construction of the composite pile of square pile, pile tube or Bamboo-shaped stake, substantially increase the efficiency in practice of construction, simultaneously, ensure that workmanship, improve cost performance.
Above embodiment is only and technological thought of the present invention is described, can not limit protection scope of the present invention with this, and every technological thought proposed according to the present invention, any change that technical scheme basis is done, all falls within scope.
