If you position the block so there's a little space between it and the wall, as shown above, then you won't have to move it again.

Pick up the wooden pole, climb onto the block, step to the edge and press Interact to place the pole in the socket.

Lara's weight pulls the pole down, raising the gate, which is just to the left. Turn so Lara is facing that way. Swing around the pole and jump forward to land near the gate. Quickly run or roll through before it closes.
