[0047] 如图 3所示，本发明的塑钢缠绕管网检査井包括井体 8、井盖 11、承压圈 10、短管 4 和短管 7。
[0048] 井体 8可以采用包括但不限于如图 4、图 5、图 6所示的在其塑胶管管壁 83上设置 直立螺旋缠绕钢带 82的带材制成的塑钢缠绕管制造。其中，在带材一侧设置折弯的搭接边 84，在钢带 82外侧覆盖塑胶保护层 81。钢带 82可以如图 4所示设置在塑胶管管壁 83的两 侧，也可以如图 6所示设置在塑胶管管壁 83的一侧，也可以如图 5所示，在图 4所示带材结 构基础上，设置内层管壁 85，并在带材未设置搭接折边一侧设置连接外层塑胶管壁 83和内 层塑胶管壁 85的塑胶加强筋 86。
[0049] 承压圈 10成环状，其中心孔孔径小丁 '井体 8的卜.端口孔径。 安装检査井时，承压 圈 10位于井体 8的上端口上方，并与井体 8的上端口保持一个安装距离 h，井盖 1 1与承压 圈 10的中心孔配合，井盖 11与地面 1平齐。
[0050] 承压圈 10的重量和其承受的压力由井体 8周围的填充土壤 9支撑。 当承压圈 10 受到路面上重物压迫时，能够均匀地将载荷传递到填充土壤 9上。
[0051 ] 为了防止填充土壤 9掉入井体 8内，在填充土壤 9和井体 8上端口之间，设置环套 在井体 8上端 U上的挡圈 200，挡圈 200的上侧与承压圈 10的下表面接触，挡圈 200与井体 8直接设置间隙 210，并采用填塞材料如沥青、麻丝等填塞，使挡圈 200既可以上下移动，又 可避免碎土进入井内。
[0052] 短管 4和短管 7沿井体竖直轴线的横向相对连接在井体 8的下端。 短管 4和短管 7的塑胶管外径小于井体 8的塑胶管外径，短管 4和短管 7插入井体 8的塑胶管壁开孔内与 井体 8密封连接。
[0053] 短管 4、短管 Ί可以采用与管网的塑钢缠绕管相同的管材，也可以采用不带缠绕加
■jffiwi '巾' trj ux's， ik^- ff u H m。
[0054] 当短管 4和短管 7采用塑钢缠绕管管材时，短管 4和短管 7的插入端可以采用两 种结构：一种是：将短管 4和短管 7插入端的缠绕加强钢带切除，在井体 8的管壁上切割 ¾ 短管 4和短管 7的塑胶管外壁相配合的孔，将短管 4的塑胶管和短管 7的塑胶管分别插入 井体 8的相应配合孔中，与井体 8的塑胶管融合密封连接。另一种是：在井体 8的管壁上切 割与短管 4和短管 7的缠绕加强钢带外径相配合的孔，将短管 4的插入端和短管 7的插入 端分别插入井体 8的相应配合孔中，釆用塑料堆焊或填充物加塑料堆焊等方法，连接和封 堵短管 4插入端和短管 7插入端与井体 8的相应配合孔。 短管 4和短管 7上的缠绕钢带也 可以采用连接钢板与井体 8上的缠绕钢带连接起来，以增强连接强度。
[0055] 短管 4和短管 7用于连接管网中的塑钢缠绕管，使管网中的塑钢缠绕管与检查井 的连接成为管道的对接连接。短管 4和短管 7的管径根据需要确定，两短管管径可以相同、 也可以不同。
[0056] 在其他实施例中，短管 4和短管 7与井体 8的连接可以采用如下结构：短管 4和短 管 7的塑胶管端部与井体 8的塑胶管壁相贯融合密封连接。
[0057] 在短管 '1和短管 7连接井体 8的端口之间，设置导流槽 6，将两端口连接起来。 导 流槽 6可以采用混凝土材料制作，也可以如图 3所示，在井体 8的底部封板 5 (为保证强度， 底部封板 5可以采用如图 7所示的带有直立设置的钢带加强肋的带材 51制作，当然，底部 封板 5不设置直立设置的钢带加强肋，不影响本发明目的的实现） 卜.设置支撑件 61，支撑采 用塑胶材料制作的导流槽 6。
[0058] 在导流槽 6的两侧，设置操作下台（图中未示出），以便对管路的维修检查。 操作 平台可以与 流槽 6的上侧平齐，也可以不平齐。 操作平台可以采用混凝土材料在检查井 底部构筑^成，也可以采用带有直立设置的钢带加强肋的带材 51制作（连接在井体 8的钢 带加强肋上和）采用塑胶材料制作的导流槽 6上，也可以直接以检査井 8的底部封板 5作 为操作平台。
[0059] 在其他实施例中，塑钢缠绕管网检查井可以不设置短管 4和短管 7，而将管网中的 塑钢缠绕管（管网中的塑钢缠绕管管径需小于井体 8的塑胶管外径）直接与井体 8的塑胶 管壁插入融合密封连接或相贯融合密封连接，检查井内设置导流槽 6连接与井体 8连接的 两塑钢缠绕管的端口。 虽然管网塑钢缠绕管与检查井井体 8的连接在现场施 T.时难度较 大，但不影响本发明目的的实现。
[0060] 如图 8所示，在短管 4、短管 7的管端与管道连接部位切割后，增强钢带的切断端面 12去锐边，裸露钢带切口 13采用与管道相同的热塑材料挤出焊接包覆。管端连接部位的螺 旋槽内设置不少于两个焊接的塑料密封块 14，密封块 14的高度与增强钢带的高度相同。

[0062] 当管网中的塑钢缠绕管管径大于等于井体 8的塑胶管外径时，检查井井体 8与管 网塑钢缠绕管的连接结构采用如图 9所示的结构：将井体 8的塑胶管下端与短管 100的塑 胶管壁相贯连接。 检查井通过短管 100与管网塑钢缠绕管连接。
[0063] 在本实施例中，短管 100采用设置直立螺旋缠绕钢带的塑钢缠绕管。 在其他实施 例中，短管 100采用不设置直立螺旋缠绕钢带的塑胶管，也能够实现本发明目的。
[0064] 在其他实施例中，井休 8的塑胶管下端可以直接与管径大于等于井休 8的塑胶管 外径的管网塑钢缠绕管的塑胶管壁相贯连接。
[0065] 当检查井采用如下结构时：
[0066] 1、短管 4、短管 7采用设置直立螺旋缠绕钢带的塑钢缠绕管，短管 4、短管 7的端部 与井体 8相贯连接；
[0067] 2、短管 4、短管 7采用设置直立螺旋缠绕钢带的塑钢缠绕管，切除短管 4、短管 7插 入端部的加强钢带，将短管 4和短管 7插入端的塑胶管插入井体 8的相应配合孔中，与井体 8的塑胶管融合密封连接；
[0068] 3、短管 100采用设置直立螺旋缠绕钢带的塑钢缠绕管,将井体 8的塑胶管下端与 管径大于等于井体 8的塑胶管外径的短管 100的塑胶管壁相贯连接 ·'
