Stratigraphic merger.
For the excavated pile, because some quotas require that the hole pile with soil and stone is calculated separately according to the different depths of the soil layer and the rock, the calculation object of the formation calculation is no longer the specific component attribute of the hole pile, but becomes the stratum category one level lower than the component attribute;The calculation carrier is no longer the component arranged in the engineering model, but becomes the formation set on the hole pile component, which is reflected as the depth of one of the distinguishing conditions of the formation excavation engineering quantity, and the depth of the formation should not only be taken from the hole depth attribute of the component, but the formation depth should be selected according to the specific requirements. In order to take into account the needs of hole pile calculation in different regions, the software designs a special processing method for the hole engineering quantity from definition, setting, analysis, statistics to output, including the following contents:
1) The method of determining the depth of the excavated pile is controlled by parameter rules. As shown in the figure, the "pile foundation" component below the calculation rule parameter rule is provided with the [method for determining the depth of the excavated pile] parameter rule on the takeoff setting calculation rule, except for method 1 and method 2 for individual areas, most of the applicable method 3 does not consider the depth of the formation, that is, the hole depth attribute of the component is taken from the component when the depth condition is specified in the quota.
2) Set the conditions for distinguishing the engineering quantity of the stratum by the earthwork definition of the engineering characteristics. As shown in Figure 4-17, there is "Ground Quantity Discrimination Condition" under the Engineering Characteristics Definition of Engineering Settings. From the dialog box that opens, you can see the criteria for distinguishing the formation quantities, in addition to the depth, there are also "diameter" (which should be understood as the aperture or side length) and "dry and wet soil". Click the Help button at the bottom of the dialog box to see the description of the settings for distinguishing conditions.
3) What you see is what you get in the component check interface. As shown in the figure, after the excavated pile is processed by the original parameter method and changed to the graphic method, what the user sees when checking the engineering quantity means what the software calculates.
4) the quantity output is not provided with the amount of ground excavation quantity project, as shown in the figure, the amount of formation excavation project of the excavated pile is no longer like other output items of the hole pile, set in the quantity of calculation setting quantity output page. Therefore, the user's habit of hooking the hole quantity from the number or component needs to be changed, and the hooking practice can only be done after the result of the statistical preview interface or the physical quantity result is obtained.
Volumizing treatment. The filling problem of the amount of excavated pile pouring engineering can be summarized into two categories:
1) According to the design pile (or wall) section expansion of a certain size, the volume of the increase in filling is reflected in the engineering quantity. In this regard, the software provides two parameter rules of [calculation method of excavated pile wall protection] [calculation method of pile core in section without wall protection section of excavated pile] on the "pile foundation" component under the calculation rule parameter rule of takeoff setting, so as to carry out differential calculation, as shown in the figure. The previous hole pile parameter [filling expansion value] belongs to this category.
2) According to the calculation of the cross-section of the designed pile (or wall), the increase in the amount of pouring material caused by filling is reflected in the quota consumption. In this regard, the software divides the core volume of the pile core into the volume of the core with the wall and the volume of the core without the wall, so as to compensate for the expansion of the consumption through the quota conversion.

After the pit grading function is executed, select the edge line that needs to be graded or modify the step height and walkway width on the large base drawing according to the prompts on the command bar. The edge line of the foundation pit has been arranged by the direction of the serial number in the system, and the selected edge serial number is displayed in the dialog box that is clicked. If you define the pit walkway order and walkway width when defining the pit number, you can see the corresponding data in the corresponding column in the dialog box. The default walkway order is 1, that is, there is no walkway in a single-stage large foundation pit, and the walkway order is not less than 2 large foundation pits, which can be edited and modified in the corresponding column.
In the dialog box, the three contents of [Excavation Depth], [Walkway Width] and [Grading Factor] can be modified as needed.
Apply All Edges] Clicking this button will match the parameters set in the dialog box to all edges of the pit.
Apply Current Edge] Click this button to modify only the selected edge order.
Cancel] Do nothing about the foundation pit and return to the original state.
Scope of construction. Function description: The building scope is mainly used for backfill deduction after the excavation of the large foundation pit in the basement. Because the basement is a space body, if the large foundation pit backfill earthwork follows the ordinary deduction of components, only the solid deduction of walls, beams, plates, columns and other components without deducting the space part, which is equivalent to filling the basement, and the result obtained is absurd. The scope of the building is to consider the area within the outer edge of the basement as a component to consider the deduction, so as to deal with the backfill calculation problem of large foundation pit with basement.
