37、table water and store it at ( 10 1) C for at least 20 h. Smooth off any uneven surface of the ice. 5.2.3.2 Type 2: Fill the ice container alternately 50 mm deep with layers of ice grains with a maximum diameter of 10 mm and 250 ml of cold potable water and store it at ( 8 2) C, for at least 20 h. Wh
38、en the ice container is full, load the ice for (5 0,5) min with a steel plate of mass (100 2) kg, the clearance between the steel plate and the side walls of the container not exceeding 10 mm. The ice block shall be used immediately for testing according to 5.2.4.3.1. The block of ice type 2 can be

Drive the ice piton into an ice block of type 1, us
41、ing a vertically guided falling body. Ensure that the ice surface is horizontal and that the ice piton is within 1 of vertical before the first drop. For the first impact, fix the drop height at (375 5) mm above the impact surface of the ice piton. For each successive impact, increase the drop heigh
42、t by the amount the piton has penetrated the ice. Hammer in the ice piton until the lower edge of the eye is in contact with the surface of the ice. Repeat the procedure, inserting and pulling out the piton slowly from the ice 100 times, without removing the ice core between the individual placement
43、s. The piton may be placed in the same ice block several times, providing the placements are at least 75 mm apart from each other and from the edges. 5.2.4.2 Determination of screwability of ice screws Fix the ice screw concentrically to the shaft of the holding device by means of the clamp. Store t
44、he ice screw and test device at ( 10 1) C for a minimum of 4 h. Place the ice screw on the surface of a type 1 ice block and adjust the holding device to keep the ice screw at right angle to the ice surface. Screw in the ice screw with a continuous contact force of (120 3) N. After a maximum of 10 t
45、urns check that the requirements specified in 4.3 are met. Complete the test within 5 min of removal from the conditioning atmosphere. 5.2.4.3 Determination of holding strength of ice anchors 5.2.4.3.1 Testing in radial direction Testing shall be carried out at a room temperature of (23 5) C. Insert
46、 the ice anchor as specified in the information supplied by the manufacturer, in the middle of the surface of a type 2 ice container prepared as described in 5.2.3.2 at an angle of (90 5). If the ice block is used smooth the ice surface around the anchor and store the ice block and test sample at (
47、18 1) C for 20 h. Apply a load by means of a (10 0,1) mm steel bar placed in the eye of the hanger of the ice anchor, as specified in the information supplied by the manufacturer, parallel to the ice surface (see Figure 4), at a rate of (100 10) mm/s until the ice anchor fails or is pulled out of th
48、e ice block or cellular concrete block. Complete the test within 3 min of removal from the conditioning atmosphere.
