Example 1

As shown in fig. 1-3, the utility model provides a be close to subway's ground even wall soil body reinforcing apparatus, be equipped with open-ended stake bucket 1 including the upside, be equipped with three vertical square groove 2 of arranging of group on the stake bucket 1, three square groove 2 of group are parallel arrangement each other, and every square groove 2 of group is four, and four square groove 2 use the axis of stake bucket 1 evenly to set up at stake bucket 1 outer wall as the center. The tank bottom of every square groove 2 all is equipped with the through-hole, every through-hole all with stake bucket 1 is linked together, equal sliding connection round bar 3 in every through-hole, and every round bar 3 stretches into the circular shape fixture block 31 of the equal fixed connection of one end in stake bucket 1, and every round bar 3 stretches out the equal fixed connection push pedal 32 of the outer one end of stake bucket 1, all cup joints spring 33 on every round bar 3, and every spring 33 all cup joints between fixture block 31 and 1 inner wall of stake bucket. In a free state, the spring 33 can pull the push plate 32 corresponding to the end of the round rod 3 to be attached to the bottom of the square groove 2, so that each push plate 32 cannot stretch out of the square groove 2. All fixed connection slider 7 on every through-hole inner wall, every the outer wall of round bar 3 all is equipped with spiral spout 71, slider 7 and spiral spout 71 one-to-one set up, every slider 7 all can slide in the spiral spout 71 that corresponds. Four guide grooves 6 which are vertically arranged are arranged between the upper side and the lower side of the pile barrel 1, and the four guide grooves 6 are evenly arranged on the outer wall of the pile barrel 1 in an annular array mode. The bottom of the pile barrel 1 is fixedly connected with a guide block 5 with a sharp thorn at the lower end, and the sharp thorn at the lower end of the guide block 5 can enable the pile barrel 1 to be pressed into a soil body more easily. Pile barrel 1 internally sliding connects with vertically arranged pile 4, and pile 4 can be pressed into the bottom of pile barrel 1 from the opening on the upper side of pile barrel 1. The side of each push plate 32 remote from the pile barrel 1 is triangular. The outer wall of the pile 4 is provided with three groups of vertically arranged clamping grooves 41, each group of clamping grooves 41 is four, the clamping grooves 41 and the clamping blocks 31 are arranged in a one-to-one correspondence mode, and each clamping block 31 is connected with the corresponding clamping groove 41 in a clamping and matching mode. Each fixture block 31 is an arc-shaped block, and the arc surfaces of the fixture blocks 31 on the same horizontal plane are opposite to each other. Stake 4 is pressing in the in-process of stake bucket 1 bottom from the opening of stake bucket 1 upside, can contact with the hypotenuse of every fixture block 31, then stretches into stake bucket 1 bottom gradually along the cambered surface, and after stake 4 stretched into stake bucket 1 bottom, every fixture block 31 all can block in the draw-in groove 41 that corresponds for stake 4 keeps fixed in stake bucket 1.

Use the utility model discloses during the underground wall soil body reinforcing apparatus of next-door neighbour's subway that embodiment 1 provided, earlier with in digging into the soil body from ground stake bucket 1, at the in-process of squeezing into of stake bucket 1, through the guide way 6 injection mud to stake bucket 1 outer wall, can accelerate the speed that stake bucket 1 was beaten into the soil body. Pile barrel 1 is from the internal back of ground driving into earth, pile 4 is pressed into pile barrel 1 bottom from the opening of pile barrel 1 upside again, the in-process of pile 4 pressing into pile barrel 1 bottom, the outer wall of pile 4 can with in proper order with the cambered surface contact of four fixture blocks 31 of three group square groove 2 one sides, pile 4 can promote four fixture blocks 31 on same horizontal plane and keep away from each other, make round bar 3 promote push pedal 32 and stretch out square groove 2 gradually, then constantly extrude peripheral soil body, make the soil body around pile barrel 1 closely knit, fasten, and also can improve the reinforcement scope of pile barrel 1 to the soil body on every side. When the push plate 32 extrudes the soil body, the contact surface with the soil body is triangular, so that the soil body can be extruded to two sides of the push plate 32, and the extrusion area of the push plate 32 to the soil body is increased. When the round rod 3 pushes the push plate 32 to gradually extend out of the square groove 2, the sliding block 7 in the through hole continuously slides along the spiral sliding groove 71 on the outer wall of the round rod 3, so that the round rod 3 can continuously rotate in the through hole in the process of pushing the push plate 32 to horizontally move, the triangular push plate 32 can advance in a soil body in a continuous rotating mode, and the protruding speed of the push plate 32 in the soil body is improved; and through the rotation of push pedal 32 in the soil body, further improve by the area that push pedal 32 can extrude peripheral soil body for the soil body around stake bucket 1 is compacter, fastens. After pile 4 is pressed into the bottom of pile barrel 1, each clamping block 31 is clamped in the corresponding clamping groove 41, so that pile 4 is kept fixed in pile barrel 1. And when the soil around the pile barrel 1 frequently shakes, the spring 33 sleeved on each round rod 3 in the pile barrel 1 can play the roles of buffering and shock absorption, so that the stability of the pile barrel 1 in the soil is improved.

To sum up, the utility model provides a ground of next-door neighbour subway is wall soil body reinforcing apparatus even, squeeze into the soil body through earlier with stake bucket 1, then impress stake 4 in 1 bottoms of stake bucket, make push pedal 32 in the stake bucket 1 can stretch out square groove 2 gradually, and extrude peripheral soil body gradually through the mode that rotates to advance, make the soil body around stake bucket 1 more closely knit, the fastening, also can improve the reinforcement scope of stake bucket 1 to the soil body around simultaneously, thereby realize consolidating the soil body and reducing the effect of the quantity of squeezing into the stake bucket.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
