This utility model discloses a positioning pillow in the field of medical pillow technology that can support a medical neck brace. It includes a headrest, a neck pillow, a raised cushion, a shoulder rest, and a neck brace. Addressing the needs of patients after cervical spine surgery, it adds an adjustable headrest, neck pillow, and shoulder rest. The headrest and neck pillow can be individually adjusted in height to suit the patient's head comfort and provide a more comfortable sleeping posture. A positioning groove is also added to fit the medical neck brace, making it more comfortable for patients to sleep with the neck brace while preventing it from sliding up and down. It does not restrict the patient's left and right head turning movements, providing a certain level of comfort while ensuring the neck brace limits the patient's neck in a set position. Even after the neck brace is removed, the device still provides neck restraint, preventing the patient from nodding or tilting their head back while sleeping, avoiding adverse neck movements during sleep, and protecting patients who have removed the neck brace while sleeping.

The application provides a single-hole double-line tunnel station integrated structure based on a variable-diameter shield, which comprises a shield tunnel and a track line, further comprises a shield station, the shield tunnel and the shield station are communicated and coaxial, a partition wall is arranged on the axis, and the track line is double-line and respectively arranged on the two sides of the partition wall; a construction method is further provided to realize the integrated structure. In the application, the double-layer station and the interval are constructed by using the variable-diameter shield method, so that the road occupation, pipeline relocation caused by the traditional open excavation method can be avoided, the pre-construction engineering such as traffic relief and green migration can be eliminated, the road zero-land occupation construction can be realized, compared with the open excavation method for constructing the station, the construction efficiency can be effectively improved and the construction period can be shortened by using the variable-diameter shield method for constructing the whole line.
