[0002] The collapsible soil structure is loose, and the structural stability is poor, and the construction work is often difficult in the building engineering construction in the soil area, and any mistake can cause a dangerous accident. Therefore, we need to use professional methods to deal with collapsible soil, which can effectively avoid the structure collapse.

[0003] When the collapsible soil foundation is treated by the compaction pile method, the pile hole is excavated, and the soil or lime soil is filled in the pile hole according to the requirements, and the foundation is efficiently rammed to improve the stability.

[0004] At present, when the pile hole is backfilled, the backfill material is usually poured into the pile hole by the shovel, and part of the backfill material is scattered around the pile hole due to the large shovel of the shovel, and the backfill material needs to be cleaned by the shovel, which is not only troublesome, but also easy to cause the hole collapse due to the high water content of the collapsible soil and the unstable soil structure.

[0005] Therefore, we propose a pile hole mouth support blanking device for collapsible soil foundation construction to solve the above problems. UTILITY MODEL CONTENTS

[0006] In view of the problem that the backfill material is usually poured into the pile hole by the shovel at present, and part of the backfill material is scattered around the pile hole due to the large shovel of the shovel, and the backfill material needs to be cleaned by the shovel, the utility model provides a pile hole mouth support blanking device for collapsible soil foundation construction.

[0007] The utility model adopts the scheme to solve the technical problem: a pile hole mouth support blanking device for collapsible soil foundation construction, including base plate, hopper and the protection cylinder for protecting the pile hole mouth and the surrounding soil structure in the backfill process,

[0008] The protection cylinder is fixedly installed in the reserved hole of the base plate, and the upper end extends out of the base plate, and the lower end extends into the pile hole;

[0009] The hopper has an open end for adding backfill material inside, and a bottom discharge port, and the bottom discharge port of the hopper is integrally connected with a hopper box;

[0010] The hopper box is installed on the upper surface of the base plate, and the side surface has a discharge channel communicated with the upper section of the protection cylinder.

[0011] Preferably, a plurality of lifting rings are fixedly installed on the upper surface of the base plate.

[0012] Preferably, the bottom discharge section of the hopper is provided with a notch, and the gate is a plug plate arranged in the notch.

[0013] Preferably, the bottom discharge section of the hopper is provided with a notch, and the gate is a plug plate arranged in the notch.

[0014] Preferably, the inside of the hopper box is provided with a guide plate.

[0015] Compared with the prior art, the utility model has the beneficial effects that:

[0016] 1、The utility model discloses a pile hole mouth supporting and discharging device for collapsible soil foundation construction, which comprises a base plate, a hopper and a casing. BRIEF DESCRIPTION OF DRAWINGS

[0017] Figure 1 It is a three-dimensional structure schematic diagram of the utility model;

[0018] Figure 2 It is a three-dimensional structure schematic diagram of the utility model.

[0019] In the drawing: 1 base plate, 2 casing, 3 hopper, 4 hopper box, 5 lifting ring, 6 plug plate, 7 guide plate. DETAILED DESCRIPTION

[0020] The utility model will be further explained in connection with the drawings and examples.

[0021] Please refer to Figures 1-2 The utility model provides a pile hole mouth supporting and discharging device for collapsible soil foundation construction technical scheme:

[0022] Example one:

[0023] According to Figure 1 And Figure 2 As shown in the drawing, it comprises a base plate 1, a hopper 3 and a casing 2 for protecting the pile hole mouth and the surrounding soil structure during backfilling.

[0024] The casing 2 is fixedly installed in the reserved hole of the base plate 1, and the upper end extends out of the base plate 1 and the lower end extends into the pile hole.

[0025] The hopper 3 has an open end for adding backfill into the interior, and a bottom discharge port. An adjustable gate is provided at the bottom discharge port of the hopper 3.

[0026] The bottom discharge section of the hopper 3 is provided with a slot, and the gate is a plug plate 6 provided in the slot. By pulling and pulling the plug plate 6, the speed and amount of the backfill material flowing out are controlled.

[0027] The bottom discharge port of the hopper 3 is integrally connected with a material box 4, which is installed on the upper surface of the base plate 1. Its side has a discharge channel connected to the upper section of the casing 2, so that the backfill material in the hopper 3 slides into the casing 2 through the material box 4.

[0028] A material guide plate 7 is installed inside the material box 4 to prevent the backfill material from being blocked or retained during the sliding process.

[0029] During specific use, the utility model is a pile hole support and feeding device for the construction of collapsible soil foundation. First, the base plate 1 is placed on the ground, and the lower section of the casing 2 is inserted into the pile hole. Then, a forklift pours the backfill material into the hopper 3. The backfill material in the hopper 3 slides into the casing 2 through the material box 4 and falls into the pile hole through the casing 2. Finally, after the backfilling is completed, the insert plate 6 is operated to stop the hopper 3 from feeding.

[0030] Example 2:

[0031] Based on the first embodiment, Figure 1 As shown, a plurality of lifting rings 5 ​​are fixedly mounted on the upper surface of the base plate 1 so that the hook of a lifting device can be connected to the lifting rings 5 ​​to lift the device.
