Description

The invention relates to the technical field of civil engineering basic engineering informatization, in particular to a prestressed pipe pile matching system and a pile matching method applied to the technical field of prestressed pile engineering informatization, and specifically relates to a BIM technology-based prestressed pipe pile matching system and a pile matching method.
Background
BIM (building Information modeling), which is a building informatization model, is a new tool for architecture, engineering and civil engineering. The term building information model or building information model was created by Autodesk. It is used to describe the computer aided design mainly based on three-dimensional figure, object guide and building engineering. The auxiliary tool is mainly used for assisting the design, construction and operation maintenance of projects in the field of civil engineering, and is an auxiliary tool capable of realizing the full life cycle management of a project.
The BIM (building Information modeling) technology is proposed first in 2002 by Autodesk company, is widely recognized in the world at present, can help to realize the integration of building Information, and all kinds of Information are always integrated in a three-dimensional model Information database from the design, construction and operation of a building to the end of the whole life cycle of the building, and personnel of design teams, construction units, facility operation departments, owners and the like can perform cooperative work based on the BIM, thereby effectively improving the working efficiency, saving resources, reducing the cost and realizing sustainable development.
The core of BIM is to provide a complete building engineering information base consistent with the actual situation for a virtual building engineering three-dimensional model by establishing the model and utilizing the digital technology. The information base not only contains geometrical information, professional attributes and state information describing building components, but also contains state information of non-component objects (such as space, motion behaviors and the like). By means of the three-dimensional model containing the construction engineering information, the information integration degree of the construction engineering is greatly improved, and therefore a platform for engineering information exchange and sharing is provided for related interest parties of the construction engineering project.
BIM has the following characteristics: the method can be applied to design and can also be applied to the whole life cycle of construction engineering projects; the design by BIM belongs to digital design; the BIM database is dynamically changed and is continuously updated, enriched and enriched in the application process; and a collaborative platform is provided for all parties participating in the project.
The existing BIM technology has the characteristics of visualization, coordination, simulation, optimization, charting and the like; and the method has the characteristics of parameterization, precision, digitalization and automatic modeling in the design process.
The PHC pipe pile is a prestressed high-strength concrete pipe pile. The hollow cylindrical precast concrete component is prepared by adopting a pre-tensioned prestressing centrifugal forming process and steam curing at about 180 ℃ under 10 atmospheric pressures (about 1.0 Mpa), the standard section length is 10m, the diameter is 300-800 mm, and the concrete strength grade is more than or equal to C80; the PC pile, namely the prestressed concrete pipe pile, is one of pipe piles, the concrete strength grade is not lower than C60, normal-pressure steam curing is generally adopted, and the pile is moved into a water pool after being demoulded and is soaked in water for curing, and the pile can be used generally after 28 days; the PTC pile is a prestressed concrete thin-wall pipe pile.
The construction of prestressed pipe piles is an important construction method in the foundation treatment technology, and the principle of the construction method is that the load generated by an upper main body structure is transmitted to a pipe pile foundation through a foundation bearing platform structure and further transmitted to a bottom rock stratum by pouring precast piles. The existing pre-stressed pile relevant specifications stipulate that the pre-stressed pile needs to be poured into a weathered rock stratum for at least 1.5 meters. As is well known, the curved surface of the original rock stratum is not absolutely flat, and the rock stratum altitudes corresponding to different coordinates are different. At present, geological exploration relevant specifications also have relevant regulations on geological exploration holes, and geological exploration units comprehensively consider factors such as ground environment, cost and the like, and do not drill holes on each pile position, so that the technical problem of uncertainty of geological conditions corresponding to the pile positions in non-drilling areas is caused.
The existing prestressed pile construction mainly adopts the methods of hammering method, static pressure method, vibration method, water jetting method, pre-drilling method and middle digging method. No matter which method is adopted for construction, piles must be matched. The existing common pile matching technology is mainly divided into an empirical method and an auxiliary technical method;
1. empirical method
The method comprises the following steps that a designer, a manager, a constructor or a pile driver operator manually pre-judges the pile length required by a pile driving position by means of materials such as geological survey results, the pile matching length of peripheral pile driving positions, original basement rock geomorphology data and the like, wherein the pile matching method adopts a conservative pile matching principle, namely length matching is preferred and length matching is not short; it is better to match the size with the big one and not with the small one. Although the pile matching scheme effectively solves the pile matching problem, the technical problems of inaccurate pile matching, inaccurate and inaccurate pile matching, informatization pile matching, surplus pile matching and the like are caused.
2. Auxiliary technical method
The auxiliary technical method for pile matching mainly comprises two main directions:
A. two-dimensional method
The two-dimensional pile matching scheme is mainly characterized in that each pile position is pre-estimated according to relevant data such as geological survey reports by means of two-dimensional design software (such as AUTOCAD (AUTO computer aided design), two-dimensional rock design software and the like), and further the approximate pile length required by each pile position is obtained.
B. Three-dimensional method
The three-dimensional pile matching scheme is that a rough geological model in a coverage area of a exploration hole is established according to geological exploration reports and other data by means of related three-dimensional design software (such as AUTO DESK related three-dimensional design software, MIDAS geological module three-dimensional design software, Bently related three-dimensional design software, Dasuo series products and the like), and further geological layers of each pile position are pre-judged by sectioning the geology of the area where the axis of the pile position is located or other technical means, so that pile matching is further guided.
The current geological exploration mode is to arrange the exploratory hole of the area to be piled and start drilling according to the design data, and obtain the geological data of the position of the exploratory hole, and to presume the geological condition of the area to be piled according to all the exploratory hole data of the area, which results in that the result is not absolute.
In the above scheme, although the problem of pile length judgment of pile matching is solved, the geological survey result obtained is not very accurate because a geological survey unit does not drill holes in each pile position in the geological survey process, so that the pile matching scheme still has the technical problem of inaccurate pile matching.
In addition, for example, in the hydraulic hammer piling process, the number of hammering and the pile penetration cannot be effectively controlled in the piling process because the geological formation condition corresponding to each pile position is unknown, and the pile is broken or broken as a result of the defect.
As known from the above, the technical problems existing in the existing pile-matching scheme are:
1. pile matching is inaccurate and piles suitable for each pile position cannot be matched;
2. the technical problem of excessive pile matching or insufficient pile matching exists;
3. there is no accurate data effort to guide the placement of each stake site.
The inaccurate pile matching means that the pile type and the pile type suitable for each load-carrying structure are not scientifically matched, and in the existing pile matching scheme, the pile type is matched according to related data given by a design unit in a field. The geological strata strength, thickness, geological stratum characteristics and other data corresponding to different pile positions are different, and in the piling process, the precast pile needs to penetrate through geological strata with different characteristics, so that the technical defect that the precast pile can be broken or broken in the pouring process is generated.
If the pile is excessive, the part exceeding the designed pile top elevation needs to be cut off, which not only wastes the pile, but also reduces the design service life of the pile; when the pile is not enough, pile splicing is needed, the pile top elevation is usually below the actual ground of the pile position, so that the pile top below the actual ground needs to be dug out, manual pile splicing is facilitated, safety risks are increased, and cost is increased.
