Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction, in particular to a pipeline inspection well. Background Art

[0002] The riding well is a special inspection well built on the pipeline, which is mainly used to facilitate the maintenance and installation of urban underground infrastructure such as power supply, water supply, drainage, sewage, communication, cable TV, gas pipes, street light lines, etc. During the construction process, it is only necessary to drill a hole on the top of the main pipe and add a well without taking any flow interruption measures.

[0003] The construction principle of the riding well is mainly based on the construction principle of manually dug piles, combined with the relevant provisions of the "Drainage Inspection Well Atlas". The upper part (well wall and well shaft) adopts the construction principle of manually dug piles, digging holes and then pouring reinforced concrete retaining walls. The lower part (well chamber) is constructed in accordance with the provisions of the "Drainage Inspection Well Atlas". The size design of the wellhead, well shaft and well chamber should be convenient for maintenance and repair, and the size and position of the ladder and footrest should also be convenient for maintenance and safety.

[0004] The horse-riding well is a common inspection well method in the pipe-jacking construction process. After the pipe-jacking is completed, a concrete sinking pipe with saddle-shaped ends is dug next to the location of the inspection well, and then the concrete sinking pipe is slowly lowered. When the concrete sinking pipe descends to the position where it connects to the pipe-jacking, it looks like sitting on a saddle, hence the name horse-riding well. In general, the design and construction of the horse-riding well fully considers practicality and convenience, and provides effective support for the maintenance and management of urban underground pipe networks.

[0005] Although the riding well has many advantages mentioned above, there are still the following shortcomings in actual use: the riding well chamber is generally a prefabricated concrete casting, which is large in size and heavy in weight, greatly increases the difficulty of construction, requires a lot of manpower and material resources, has low work efficiency and high construction cost. Utility Model Content

[0007] The utility model is realized through the following technical scheme: a pipeline inspection well, including a riding well chamber installed on an underground water pipe, the riding well chamber including an upper well chamber and a lower well chamber, the upper well chamber and the lower well chamber are butted up and down to form a complete riding well chamber; a well cover is arranged at the top of the upper well chamber, a storage groove is opened at the bottom end of the upper well chamber, a sealing rubber bag is arranged inside the storage groove; a protrusion corresponding to the storage groove is arranged at the top end of the lower well chamber, the protrusion is inserted in the storage groove and can break the sealing rubber bag, and a semicircular opening corresponding to the underground water pipe is arranged at the bottom end of the lower well chamber.

[0008] A further improvement of the utility model is that the storage groove is arranged along the bottom periphery of the upper well chamber, thereby forming a closed annular groove; and the protrusion is arranged along the top periphery of the lower well chamber, thereby forming a closed annular convex strip.

[0009] A further improvement of the utility model is that the cross sections of the storage groove and the protrusion are both conical structures.

[0010] A further improvement of the utility model is that positioning slots are arranged on both sides of the upper well chamber, and positioning plug plates corresponding to the positioning slots are arranged on both sides of the lower well chamber.

[0011] A further improvement of the utility model is that the positioning slot is arranged on the outside of the storage groove, and the outer side surface of the positioning slot is an open structure.

[0012] A further improvement of the utility model is that the top end of the positioning plug plate is an arc structure.

[0013] From the above technical scheme, it can be seen that the beneficial effects of the utility model are: the design of the inspection well is reasonable, the structure is simple and ingenious, the riding well chamber adopts a split structure, which is easy to install, greatly reduces the difficulty of construction, has high work efficiency, saves manpower and material resources, and is suitable for promotion.

[0019] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in conjunction with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0020] Please refer to the attached Figure 1 —3, combined with a specific embodiment, it is explained as follows: A pipeline inspection well described in the utility model includes a riding well chamber installed on an underground water pipe 4, and the riding well chamber includes an upper well chamber 1 and a lower well chamber 2, and the upper well chamber 1 and the lower well chamber 2 are connected up and down to form a complete riding well chamber; a well cover 3 is provided at the top of the upper well chamber 1, and a storage groove 6 is opened at the bottom end of the upper well chamber 1, and a sealing rubber bag is provided inside the storage groove 6; specifically, the storage groove 6 is arranged along the periphery of the bottom end of the upper well chamber 1 to form a closed annular groove; a protrusion 8 corresponding to the storage groove 6 is provided at the top of the lower well chamber 2, that is, the protrusion 8 is arranged along the periphery of the top end of the lower well chamber 2 to form a closed annular convex strip; the protrusion 8 is inserted in the storage groove 6 and can break the sealing rubber bag, and the bottom end of the lower well chamber 2 is provided with a semicircular opening corresponding to the underground water pipe 4.

[0021] The use principle of the utility model: an underground water pipe 4 is set with reference to the existing construction process, and a concrete layer 5 for installing the riding well chamber is set at the bottom of the underground water pipe 4. The staff uses the lifting equipment to first install the lower well chamber 2 on the prefabricated lower well chamber 2, and then uses the lifting equipment to dock the upper well chamber 1 with the lower well chamber 2. During the docking process, the protrusion 8 is inserted into the storage groove 6, and the protrusion 8 will also break the sealant bag. After the sealant bag is broken, the concrete joint glue in the sealant bag is squeezed out under the action of the protrusion 8, and the concrete joint glue can seal the joint between the upper well chamber 1 and the lower well chamber 2. After the docking is completed, the staff installs the manhole cover 3 on the top of the upper well chamber 1, that is, the riding well chamber is installed. It can be seen that the riding well chamber is divided into two, which is a split splicing structure. This structure effectively reduces the volume and weight of the components, thereby reducing the difficulty of construction.

[0022] In one embodiment, the cross-sections of the storage groove 6 and the protrusion 8 are both conical structures. With the above structure, the protrusion 8 can better break the sealant bag; at the same time, the protrusion 8 can also better squeeze out the concrete sealant in the sealant bag and squeeze the concrete sealant out of the storage groove 6.

[0023] In one embodiment, positioning slots 7 are provided on both sides of the upper well chamber 1, and positioning plugs 9 corresponding to the positioning slots 7 are provided on both sides of the lower well chamber 2. With the above structure, it is convenient for the staff to dock the upper well chamber 1 with the lower well chamber 2.

[0024] In one embodiment, the positioning slot 7 is arranged outside the storage groove 6, and the outer side of the positioning slot 7 is an open structure; the top of the positioning plug plate 9 is an arc structure. Through the above structure, the positioning plug plate 9 can be easily inserted into the positioning slot 7.
