[0002] There is a sealed cylinder around the target station of the neutron bombardment station, and its structure is as follows: figure 1 and figure 2 As shown, the center of the sealing cylinder 0 is located in the center of the target station. The sealing cylinder 0 is a reinforced concrete structure with multiple anchors inside. The bombardment station has high requirements on the accuracy of the anchors. The bolt adjustment and positioning method is in the process of adjusting the bolt unknown. When adjusting the rear bolt, it is easy to cause the position of the previously adjusted bolt to change, thereby affecting its position accuracy, and it is difficult to guarantee the position accuracy of the bolt.

Embodiment 1
[0027] A method for accurately installing the anchor rod of the sealing cylinder of a target station, comprising the following steps:
[0028] a. Make the base positioning sleeve 5: as Figure 5 As shown, the base positioning sleeve frame 5 is annular and is assembled from eight (or other number of) annular steel plates 51, and nine (or other number of) annular steel plates 51 are drilled on each annular steel plate 51. a plurality of) anchor rod positioning holes 53;
[0029] b. Pre-embedding of base positioning sleeve steel bar diagonal brace 10 and anchor angle steel 11: if image 3 As shown, the base positioning sleeve steel bar diagonal brace 10 forms an angle of 65° with the horizontal plane (it can also be any angle between 60° and 70°), and is arranged in equal parts along the circumference of the ring where the sealing cylinder 0 is located, extending into The bottom concrete 12 is pre-embedded; anchor rod angle steel 11 is pre-embedded four around the pre-determine...

The invention relates to the field of construction and concretely relates to an accurate installation method for a target station sealing chamber anchor rod. The installation method comprises preparing a pedestal positioning sleeve rack (5), pre-burying a pedestal positioning sleeve rack reinforced steel bar inclined support (10) and anchor rod angle steel (11), casting base layer concrete, installing the pedestal positioning sleeve rack (5) and the anchor rod (7), lofting the lower end of the anchor rod, welding round steel having a flange and adjusting a plane position of the anchor rods (7) till an accurate position. By the use of the accurate installation method, the pedestal positioning sleeve rack can be conveniently installed and installation precision can be adjusted; and the anchor rod can be easily adjusted and the plane position of anchor rods can be guaranteed.
Description
technical field [0001] The invention relates to the field of construction, and more particularly to a method for accurately installing a bolt of a sealing cylinder of a target station. Background technique [0002] There is a sealed cylinder around the target station of the neutron bombardment station, and its structure is as follows: figure 1 with figure 2 As shown, the center of the sealing cylinder 0 is located in the center of the target station. The sealing cylinder 0 is a reinforced concrete structure with multiple anchors inside. The bombardment station has high requirements on the accuracy of the anchors. The adjustment and positioning method of the anchor rod is in the unknown process of adjusting the anchor rod. When adjusting the rear anchor rod, it is easy to cause the position change of the previously adjusted anchor rod, which affects its position accuracy, and it is difficult to guarantee the position accuracy of the anchor rod.
