Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to fig. 1 to 5 and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The embodiment of the application discloses a tunnel construction plan generation method.
Referring to fig. 1, a tunnel construction plan generation method includes:
step S101, geological condition data of a current face pile number are obtained; the geological condition data comprise surrounding rock types, specific geological condition monitoring data and harmful gas monitoring data;
the tunnel face is a construction face which is gradually pushed to the outlet direction from the inlet in the tunnel construction process according to a certain working procedure and a construction method. The location of a face is typically determined by a pile number, which is a numbering system used to identify the location in an engineering such as a tunnel or road. And the constructor determines the current construction position according to the pile number of the face, and accordingly evaluates geological conditions, determines a construction method, controls construction progress and the like.
It should be noted that the pushing and construction of the tunnel face are a cyclic process, and are repeated until the exit position of the tunnel design is reached. On the tunnel face, constructors perform working procedures such as tunneling, supporting, drainage, ventilation and the like, and work is performed according to construction technology and design requirements. Once the current working procedure and operation of the face is completed, the face will advance a certain distance into the next face. By grasping the position and the progress of the tunnel face, the tunnel construction can be effectively managed and controlled, and the smooth progress of the construction quality and the progress is ensured.
The geological condition data can be obtained through advanced geological forecast data or construction design data; in the process of acquiring the geological condition data, if the advanced geological forecast data exists, the advanced geological forecast data is directly acquired, and if the advanced geological forecast data does not exist, the geological condition data in the construction design data is used as the reference. In one embodiment of the present application, the construction design data is the result of geological survey at the time of design, including surrounding rock category of a certain pile number range (start pile number-end pile number), specific geological condition (such as water gushing or not), and harmful gas condition (such as gas, etc.), and these data are gradually replaced by advanced geological forecast data as the tunnel construction is developed.
In some embodiments, advanced geological forecast data refers to data for predicting and evaluating surrounding rock and stratum conditions in front of a tunnel face before construction by using modern geological exploration technology and analysis methods in the tunnel construction process, wherein the data comprises information such as surrounding rock types, geological structures, groundwater conditions, harmful gas conditions, engineering geological conditions and the like, so as to help constructors know and predict possible bad geological disasters, and accordingly, corresponding construction plans and safety guarantee measures are formulated.
Step S102, determining a corresponding construction method according to the category of surrounding rock based on a preset construction method library;
in some embodiments, tunnel surrounding rock categories may be classified into six classes according to rock hardness, integrity, stability, internal construction, etc., as specified in the highway tunnel engineering construction and quality acceptance Specification; wherein, the first-stage surrounding rock is best, basically a whole hard stone, the sixth-stage surrounding rock is worst, and basically broken loose soft soil mass. The construction methods to be used are different according to the types of surrounding rocks, for example, a common construction method is a two-step method, a three-step method, an up-down-step method, a full-section method and the like.
In one embodiment of the present application, a preset construction method library is established by standardizing and standardizing the construction methods corresponding to each surrounding rock category, where the preset construction method library includes preset mapping relations between multiple groups of surrounding rock categories and construction methods, and each surrounding rock category is configured with a corresponding construction method.
Step S103, corresponding specific construction measures are determined according to the specific geological condition monitoring data and the harmful gas monitoring data;
the special geological conditions such as water burst, fault or weak interlayer and the like; in the embodiment of the application, each specific geological condition and the condition that the harmful gas exceeds the standard are correspondingly configured with corresponding specific construction measures, for example, when water gushing occurs, measures such as dewatering and drainage, water blocking curtains, reinforcing supports and the like are needed to be adopted; when faults or weak interlayers and the like occur, measures such as reinforcing support and the like are needed; when detecting that harmful gases such as gas exceeds standard, ventilation, sealing, fire prevention, explosion prevention measures and the like are needed, so that the safety of tunnel construction is ensured.
Step S104, performing procedure operation adjustment on the construction method according to specific construction measures to generate corresponding construction procedures;
it can be appreciated that, since each standardized construction method further includes a plurality of working procedures, for example, a two-step method includes working procedures of upper step excavation, primary support, lower step excavation, two lining, etc., each working procedure is formed by a series of steps, and the steps are operations; after the corresponding specific construction measures are determined, the construction method can be adjusted in terms of the working procedures, for example, the specific working procedures or the working procedures are added or subtracted, so that the adjusted construction working procedures can be generated.
Step S105, determining a preset circulating footage of the face pile number according to the surrounding rock category and the construction method;
the circulating footage refers to the forward pushing distance of the pile number of the face after each blasting or tunneling in the tunnel excavation process;
in some embodiments, a plurality of circulating footage historical data corresponding to the surrounding rock category and the construction method can be obtained according to the historical construction database, and an average value is calculated through the plurality of circulating footage historical data, so that the average value can be used as a preset circulating footage corresponding to the surrounding rock category.
Step S106, determining the corresponding construction operation prediction duration according to the surrounding rock category, the construction procedure and the preset cyclic footage;
in some embodiments, according to surrounding rock types, construction procedures, preset cyclic feeding rules and other influencing factors influencing the tunnel construction operation duration, prediction of the construction operation duration can be performed through historical data moving average, neural network model prediction and other modes, so that the predicted operation duration of each operation in the construction procedures can be determined.
Step S107, receiving construction organization information input by a user, and generating a corresponding tunnel construction plan by combining a construction procedure and a construction operation prediction duration.
The construction organization information includes equipment arrangement information such as division of construction work areas, construction groups of each work area, the number of persons at each post, and the type and number of construction equipment.
In the above embodiment, the geological condition data such as the surrounding rock category of the current face pile number, the specific geological condition monitoring data, the harmful gas monitoring data and the like are obtained from the advanced geological forecast data or the construction design data, so that the geological condition of the construction area can be comprehensively known, wherein the corresponding standard construction method can be obtained according to the surrounding rock category, so as to ensure that the construction method is matched with the geological condition; corresponding specific construction measures can be obtained according to the specific geological condition monitoring data and the harmful gas monitoring data so as to reduce construction risks; and (3) performing procedure adjustment on the construction method according to specific construction measures to ensure smooth construction process, determining a preset cyclic footage of the face pile number and a corresponding construction operation prediction duration according to surrounding rock types and the construction method, and generating a corresponding tunnel construction plan by combining the construction operation prediction duration, construction organization information input by a user and the adjusted construction procedure.
In the method, the geological condition data are accurately acquired, the construction method is flexibly selected according to the actual geological condition of a construction site, specific construction measures are adopted to adjust working procedures, meanwhile, the circulating footage and the predicted duration of construction operation are reasonably determined, and the tunnel construction plan is generated by combining construction organization information, so that the construction efficiency is improved, the construction risk is reduced, and the smooth progress of tunnel construction is ensured.
In the process of generating the tunnel construction plan, the tunnel face pile number needs to be continuously cycled from the entrance pile number of the tunnel design to the tunnel construction plan generating step of the step S101 to the step S107 until reaching the exit pile number of the tunnel design, so as to effectively control the progress period of the whole tunnel construction and improve the accuracy of the construction plan.
