TRENCH/PIT LAYOUT 挖沟/坑布局

Overview 概述

Use this section to define the number of trenches and the trench characteristics. This system works equally well with both trenches and pits. In the case of a pit installation, think of each trench as a row of pipe in the pit and then define the row layout.
使用本节中定义的管沟数量和管沟属性,同时适用于挖沟和挖坑布局。在挖坑安装的情况下,我们将每个坑看作是一行管沟进行布局设计。

PIPE CONFIGURATION IN TRENCH/PIT 管沟/坑中的管道配置

Overview: 概述

Now that you have entered the general trench configuration (or row configuration, in the case of a pit installation), this section enables you to focus on defining the pipes in the trench/pit rows.
此时你已经输入了总的管沟配置(或在挖坑安装中的行配置),本节专注于管沟中的管道定义。

Details for each configuration: 配置详情:

In this arrangement, the user creates a single column of pipes. The number of pipes chosen defines how many layers will be included. Each pipe is separated from its neighbor by the given vertical separation [Y], starting from the bottom of the trench. If the ‘Offset’ box is checked, each pipe layer will be shifted from the pipe layer below by the given horizontal separation [X]. Use this arrangement for pipe rows in a pit system.

用户使用单列管道,管道数量与层数相同。相邻管道的垂直间距为[Y],从管沟部开始计算。如果“偏移”选项框选中的话,每层管道与下层管道的水平方向间距为[X]。此配置适用于挖坑系统。

In this arrangement, the user creates two-pipe layers. The number of pipes chosen defines how many layers will be included ( 2 , 4, 6, etc.). Each vertical layer is separated from the one above or below by the given vertical separation [Y]. If the ‘Offset’ box is checked, each pipe layer will be shifted from the pipe layer below by one-half the given horizontal separation [X/ 2 ].

用户使用双列管道布局。管道数量(2/4/6等)决定了层数,每层与相邻层的垂直间距为[Y]。如果“偏移”选项框选中的话,每层管道与下层管道的水平方向间距为[X/2]。

In this arrangement, the user defines three pipe layers. The number of pipes chosen defines how many layers will be included (3, 6, 9, etc.). Each vertical layer is separated from the one above or below by the given vertical separation [Y]. If the ‘Offset’ box is checked, every layer will be shifted from the layer below by one-half the given horizontal separation [X/ 2 ].

用户使用三列管道布局。选择管道的数量定义将包括多少层(3,6,9,等)。管道数量(3/6/9等)决定了管道层数,每层与相邻层的垂直间距为[Y]。如果“偏移”选项框选中的话,每层管道与下层管道的水平方向间距为[X/2]。

In this arrangement, the slinky is placed vertically within a trench and is resting at the bottom. The trench may be as narrow as the pipe and soil allow.

本配置为在管沟底部垂直放置一组螺旋管,此时挖沟宽度可以窄到与管道尺寸接近。

In this arrangement, the slinky is placed horizontally at the bottom of the trench. The minimum trench width depends on the slinky diameter. Use this arrangement for slinky rows in a pit system. 本配置为在管沟底部水平放置一组螺旋管,此时挖沟宽度取决于螺旋直径。

EXAMPLES: 示例:

Pit System 1 挖坑系统 1

The design calls for an 8 foot deep excavated pit with 6 rows of horizontal slinkies. The center-to-center distance/separation between slinky rows is 8 feet. Because the slinky diameter is 36 inches, the trench/row width is also 36 inches. Input data should look like this:

坑深度8英尺,水平放置6行螺旋管,螺旋直径为36英寸(坑的宽度也为36英寸),螺旋管间的中心间距为8英尺。

Pit System 2 挖坑系统 2

The design calls for an 8 foot deep excavated pit with 6 rows of horizontal slinkies. The edge of one slinky row needs to be 8 feet away from the edge of the next slinky row (in Pit System 1, there is an 8 ft separation from center to center and in this example, there is an 8 ft separation between the edges of slinky rows. Input data should look like this:

坑深度8英尺,水平放置6行螺旋管,螺旋管间的边缘间距为8英尺(上例挖坑系统 1为相邻螺旋管中心间距为8英尺)。数据输入如下图:

Notice that in this case, the separation is 11 feet! This is because the separation (as defined by the program) measures the center-to-center distance between rows. However, the input specification we have in this example is distance between the edges of the slinkies in the rows. Since the slinky diameter is 36 inches, the slinky radius is 18 inches. From center to center, we therefore have 8 feet (as per the spec) + 18 inches (for the distance from the center of the slinky to the edge of the slinky) + 18 inches (for the distance from the center of the next slinky to the edge of the next slinky) = 8 feet + 36 inches = 11 feet.

值得注意的是,此例中的间距为11英尺!这是因为间距参数被程序定义为相邻螺旋管行的中心间距。但本例要求的是相邻螺旋管行的边缘间距为8英尺,而螺旋管螺旋直径为36英寸(即36/12=3英尺),计算可得中心间距为11英尺。

Trench System 1 挖沟系统 1

The design calls for 10 trenches that are 8 feet deep and that are separated from one another by 6 feet (6 feet separation from trench center to trench center). Two layers of double pipes will be placed in each trench. In each trench, the pipes will have a 12 inch horizontal separation and a 12 inch vertical separation. Each trench will be 12 inches wide. Input data should look like this:

10条管沟,8英尺深,相邻管沟中心间距6英尺。每管沟2层双管道布置。每条管沟内,管道的水平间距为12英寸,垂直间距为12英寸,管沟宽度为12英寸。数据输入如下图:
